Rooting Blackview A20 - Upgrading, Modifying and Unlocking

I have a blackview A20 which is a low spec phone running android oreo go.
I would like to use this phone for experimentation with android development and learning about android on a cheap device without risk of breaking my main phone. To do this I would like it rooted and as a bonus with a custom recovery so I can test custom ROMs.
State of device:
Unlocked bootloader
Unchanged ROM
Unchanged Recovery
OEM unlocking enabled
USB debugging enabled
What I have tried:
Flashing recovery images with fastboot
Using fastboot flash recovery recovery.img with some TWRP and CWM recovery images all yield:
target reported max download size of 134217728 bytes
sending 'recovery' (4690 KB)...
OKAY [ 0.169s]
writing 'recovery'...
OKAY [ 0.276s]
Click to expand...
Click to collapse
finished. total time: 0.448s
or similar. Then I restart phone and select boot into recovery mode. The phone hangs for a small while before restarting and booting into the normal OS. On restart into recovery the unchanged recovery is there still.​
Various 'one-tap' methods
All of which were unsuccessful. If needed I can give details.​
Installing SuperSU zip from recovery
In a futile attempt I tried to use the android recovery to push a SuperSU zip with its update from zip option. I knew this wouldn't work but I found something interesting. On the Apply update from SD card option I get an error saying couldn't mount /sdcard​
Booting recovery images with fastboot
I have tried the fastboot boot recovery.img command to try to boot directly into the images. I get this
downloading 'boot.img'...
OKAY [ 0.211s]
booting...
OKAY [ 0.047s]
finished. total time: 0.261s
Click to expand...
Click to collapse
output but the device just restarts and boots normally into the normal OS.​
What I would like from this question (In order of importance):
A way to root the device
A way to access a custom recovery (even if temporary)
Ability to install custom ROMs
A permanent custom recovery

I don't have this device but, you may find the following threads helpful because they, apparently, are compatible with your specific device. Don't be afraid to ask for some member guidance within one of them too.

Hello,
I'm also trying to root the Blackview A20 with no success. Where you able to find a way?
Thanks!!

I'm afraid I still haven't found a way. Other than TWRP or something making a custom recovery specifically for this phone I don't see a way to root it at all. Sorry

I have a Blackview A20 Pro (note this is probably different in specification to the A20) - Here is how I rooted it by using Magisk on a boot image read and written using SPFlash tools. I had previously unlocked the bootloader on the phone by using the Developer option for OEM unlock and then fastboot unlocking as standard.
- Obtain the MT6739_Android_Scatter file from an archive of the a20 stock rom available by googling
- Install Magisk manager apk on the phone
- Run the latest version of SP Flash tools on the PC with the associated drivers. Load the scatter file in to it.
- Work out the size of the boot partition by subtracting the start value of the next partition (Logo) from the start position of (Boot)
- I did using Windows calculator in programmer mode - set to hex, subtract the two values. Note the start position of the boot partition
- Go to the Read Back page, add an item to read back, enter a filename to save it like a20-stock-boot-image.img and then enter the start position of the boot partition and the size you calculated. Make sure to get them exactly correct and avoid changing the number of digits in the entry box as I don't know how fussy sp-flash tools is.
- Unplug the phone from PC if it is plugged in and remove the battery.
- Tell SP Flash tools to start the read-back
- Plug the phone in, within a few seconds it should read and save the boot partition from the phone. Keep this backed up. File should be something between 8-25mb I would expect.
- Put the battery in the phone and power it up and unplug/plug it in to the PC via usb and then in the notification area on the phone select "Transfer Files" from the very bottom so it appears to your PC as a drive.
- Drag over the stock boot image from your PC somewhere on the phone - like the Downloads folder.
- On the phone open magisk and select install - when prompted select to use local boot image, select the stock boot image file you transferred
- Magisk should now patch this file - make sure the text it outputs looks like it recognized the boot image and is working.
- Now unplug and replug the phone to PC as I found PC doesn't seem to see new files on the phone. Pull over the patched boot image Magisk has made. Don't worry if this is smaller than the original file. The extra bytes were likely just zeros.
- Using SP Flash tool, go back to the Download screen and select the patched boot image for the boot partition. This will write the new boot image to your phone.
- Power down the phone and remove the battery.
- Tell SP flash tool to start and then plug the phone in with no battery. It should then flash the patched boot image.
- Put the battery back in and boot the phone. When you open magisk app on the phone now it should say you are rooted.
Enjoy!
If it doesn't work, repeat the download process with the stock boot image you saved and that should restore things to how they were before. I assume if it doesn't work it will just be because you need to unlock the bootloader or because your phone is different to the scatter file, but in that case I would expect Magisk to fail to patch it before you get to that stage.

How do you remove the battery? Have I missed something?
Sorry, wrong phone!!

Stuck on installing ROM

So as a fan of Android and ICT literate I decided to root, new recovery and install a new ROM to get my favourite MediaPad M2 8.0 LTE as stock Android as possible.
I unlocked the bootloader, installed TWRP successfully and it works.
However on my haste I messed up my android ROM install. No problem: got TWRP, just find a new stock ROM to install except unlike my phone it seems it's not that simple with this tablet?
I'm picking up that you cannot install a true stock Huawei ROM without losing TWRP. Not great but okay.
Downloaded a stock ROM, used Huawei extracter to pull the recovery IMG and flashed via TWRP.
Booted up and it goes straight to Huawei's own fastboot screen and Huawei's own software won't recover.
I've flashed TWRP back again for now.
So I basically need a ROM I can install from fresh which will install via TWRP.
Am I right that the official Roms are out due to the recovery requirements?
Have I missed something obvious to get this tablet alive again?

First of all, I'm not sure whether flashing the official Huawei partition images will work if they are flashed from TWRP (I've never tried it). However, I do know that it works without problems when flashed in fastboot mode. Secondly, if TWRP was flashed as the recovery and you chose the TWRP inbuilt root option, it would have replaced your BOOT partition as well. So to repair this, you'd have to flash the official Huawei BOOT partition as well. BTW, I was in a similar state (bootloop/no boot) a couple of times (see my post here) and both times was able to recover by flashing the official Huawei BOOT.img and RECOVERY.img partitions to my device.
So, to get your device back into a decent shape, try flashing the BOOT.img as well as the RECOVERY.img from the official Huawei ROM for your device, performing the flashing in fastboot mode. I have written a guide which details extracting and flashing official Huawei partitions. Best of luck
It is obvious that I am missing something very simle here and I'm very interested in finding out what it is I'm doing wrong
So I have a TWRP booting tablet.
I downloaded the latest image from the roms thread on this forum which gives me a zip file called "M2-801LC100B205.zip".
I extract this and open it in Huawei extracter tool.
I extract the BOOT, RECOVERY, SYSTEM and CUST to separate .img files.
I flash all 4, one after the other using the commands listed in your guide:
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
They all flash okay (it seems), an exmaple of the flash is:
C:\platform-tools>fastboot flash system SYSTEM.img

C:\platform-tools>
But still I have a tablet that is stuck on the boot screen. I can still get back to the fastboot recovery so I can still flash but I seem to be missing WHAT to flash?
Surely there must be a complete .img file some where I can flash in flash boot which will just get the thing back and working?
It seems like I'm flashing lots of small simple things when I just want a complete image from some where to flash?
I cant flash the downloaded zip files via fast boot it seems?
Does one exist of have I missed some thing?
Update:
I downloaded a ZIP file of a full rom as detailed above, installed TWRP and tried to flash the zip: it fails stating it could not mount the system partition and radio firmware does not exist. I assume this is because the file downloaded is an update and not a complete rom?
I used TWRP to format and resize the system partition and it reports 0mb in size and fails.
I really think I just need a plain original simple complete rom to flash, in a ZIP format for TWRP: the updates all seem to assume its being flashed onto a working system as an update and I don't have a full base install.
Surely this base simple rom must exist some where?
Any one?
Next step for this tablet is to return it unfortunately as I'm totally beat
Does any one have a TWRP backup I can flash for a media pad m2 lte 8.0?

Hmmm... I expected you to only flash the boot and recovery images as mentioned in my previous reply (and not other partition images, the example text in my guide was just that - an example) from your original ROM version, not from a downloaded ROM version. If your original ROM was a lollipop ROM and not marshmallow, B205 is a mm ROM and would require a full ROM flash, and in this case a bits-and-pieces flash would not work, and cause a non-booting device. A bits-and-pieces flash especially of any device partition other than BOOT and RECOVERY should ideally be done only with the ROM version which is currently installed and (previously known to be) working.
If you can connect the phone to your computer long enough to transfer over the full ROM image to the device, you should be able to flash that using the original Huawei recovery. The instructions are present on the forum thread where you found the ROM. Alternatively, if you know what version the original ROM was on your device, you can flash its SYSTEM and CUST over.
Yes, that's what I would like to do and I can do that, fast boot still works, but it's where do I get a FULL ROM from? Everything on this forum I have found is an update and relies on another working ROM to be present.
Where do I get the full ROM from, do we know the name of one which is not an upgrade ROM?
It's this full ROM I've been looking for to no avail
Please confirm your device model and I'll try to find a full ROM image download (Marshmallow) for you.
EDIT: by full I mean a ROM which is a complete image (about 2-3GB) instead of a partial OTA update. Also, I'm not certain that you can flash a full Huawei official ROM image from fastboot; it requires booting into the recovery. AFAIK Booting into the recovery does not need a working ROM system partition.
Thanks for this! So as I cannot get into android, I've looked on the physical back of the device and it says it's a m2-801L. I purchased a Huawei MediaPad 8.0 LTE. I can flash the Huawei standard recovery and boot fine, I can flash from that and have tried to flash parts of Roms from that so I assume a full ROM is a similar process?
Also would a full TWRP backup also not work?
Thanks again for all your help however, I'm happy to buy you a beer (or non alcoholic beverage of your choice!l
Sorry to bug but have you, or any one else, had any luck in finding a full rom?
Any one have a twrp backup of a basic fulll booting rom I could try?
I do appreciate all the help!

Sorry for the delayed reply, I've been pretty ill for the last few days.
Here are links to what I'm pretty certain are the OEM Lollipop full ROMs for the 801L. All those links are 1.4GB zipped, which means that they should unzip to about 2.5-3GB, which indicates that it is a full ROM:
801L B006 on Huawei Malaysian support site: http://download-c.huawei.com/download/downloadCenter?downloadId=57706&version=181649&siteCode=my
801L B007 on Huawei Malaysian support site: http://download-c.huawei.com/download/downloadCenter?downloadId=71503&version=254039&siteCode=my
801L B003 on Huawei Russian support site (): http://download-c.huawei.com/download/downloadCenter?downloadId=71523&version=254048&siteCode=ru
You'll need to get the unzipped ROM folder onto your external SD card somehow, to be able to flash it with the Huawei recovery.
Here are some steps you can follow:
Part 1: Download ROM, extract it and then copy extracted ROM directory to sdcard on phone
In this part, we will download the ROM, extract it, and transfer the extracted ROM to your M2 using TWRP and ADB. Make sure that you have the Mediapad drivers installed, and adb and fastboot installed and available.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.
On Linux, just install the Android Command Line tools from Google.
For the phone drivers, just install HiSuite from Huawei - this will install the Mediapad device drivers. You can then uninstall HiSuite - the drivers will still continue to remain installed even if HiSuite is uninstalled, and this way you won't clutter up your computer with the useless HiSuite.
Now download one of the ROMs listed above (I suggest starting with B007. If that doesn't work, try B003 and then B006).
Unzip the downloaded ROM onto some location on your computer's hard drive. Let's say that on Windows, you unzip it to D:\MYROM
In D:\MYROM, you should find a directory called dload
Make sure that you have TWRP as the recovery on the phone. Flash TWRP onto the phone if you need to (since you already know how to do this, I won't go into more detail).
Boot into the TWRP recovery on the phone (since you already know how to do this, I won't go into more detail).
In TWRP, make sure that MTP mode is off. To do this, in the TWRP main menu, press "Mount". In the "Mount" screen, check whether the second (right-hand-side) button on the bottom reads "Enable MTP". If it says "Enable MTP", then you do not need to do anything else here, go back to the main TWRP screen. If the button says "Disable MTP", press it so that the button now reads as "Enable MTP". Setting MTP mode off will ensure that you can connect via ADB to your phone.
Now open a terminal/command-prompt window on your computer (Run->"cmd" or search for "cmd" on Windows).
In the terminal window, navigate to the directory where the unzipped ROM is present. On Windows, using the above example ROM unzip location, you would type
Code:
d:
cd D:\MYROM
Type the following ADB command to make sure that your phone is recognized by ADB:
Code:
adb devices
If it works, you should see something like
Code:
List of devices attached
ABCD1234567890 recovery
where "ABCD1234567890" will actually be your device ID string, and not literally "ABCD1234567890"
If you see a string like the above, good news, it means that your phone is recognized by ADB, and we can now transfer the unzipped ROM to your SD card. If you do not see anything after the "List of devices attached" string, make sure that you have turned off MTP mode in TWRP as detailed above. If you still don't get anything, you will have to transfer the unzipped ROM to your sdcard by some other means - perhaps by putting the SD card in another phone. Skip the rest of the steps here and see Part 1.5 below.
Now type the following command in your computer's terminal window (command below is for Windows; on Linux, replace "D:\dload" with the appropriate path to the dload directory):
Code:
adb push D:\MYROM\dload /sdcard
This will copy the extracted ROM's "dload" directory to the root of your internal SD card. To copy it to the root of your external SD card, replace "/sdcard" in the above command with "/external_sd".
If all went well with the above command, then at this point your extracted ROM's "dload" directory should have been copied over from your computer to your phone (either on the root of the internal SD if you used "/sdcard" in the "adb push" command, or on the root of the external SD if you used "/external_sd" in the "adb push" command. Go to Part 2 below.
Part 1.5: Copy extracted ROM directory to external sdcard on phone using another phone.
SKIP THIS PART IF YOU SUCCESSFULLY COMPLETED ALL STEPS IN PART 1 ABOVE, AND GO TO PART 2 BELOW!
Remove the external SD card from your M2.
Insert the external SD from the M2 into some other phone/device.
Connect that phone to your computer via USB.
Transfer the unzipped ROM's "dload" folder to the root of the SD card.
Remove the SD card from the other phone and put it back into your M2.
Part 2: Flash official Huawei BOOT.img and RECOVERY.img and installed extracted ROM using official Huawei Recovery
In this part, we will replace TWRP with the official Huawei recovery and boot partitions, and use the official Huawei recovery to flash the ROM on the phone.
From the ROM you downloaded in Part 1 above, extract BOOT.img and RECOVERY.img using the Huawei Update Extractor. Since you already know how to do this, no further details will be given.
Flash the official Huawei BOOT.img and RECOVERY.img partitions (for safety, do not flash any other partitions) onto your M2. to refresh your memory on how to do this, see my guide.
After successfully flashing the official Huawei BOOT.img and RECOVERY.img partitions to your M2, you can flash the downloaded ROM as an update by booting into the Huawei recovery which you just flashed onto your M2. After booting into the Huawei recovery, it should automatically detect and start installing the downloaded ROM.
Hope this helps. Good luck!

Hello, "different customer" here
I came into the same situation, a while ago I wiped a lot of things (through TWRP) making my tablet unbootable, I was trying to recover from a bootloop.
I followed this well written guide but the stock recovery won't detect the new ROM (I have a dload folder with META-INF directory inside and UPDATE.APP).
I flashed the BOOT.img and the SYSTEM.img while at fastboot mode. At the sdcard there is a folder dload with the rest.
Booting up with pressed + and - is starting to "Installing update" but hangs at 5%
What should I do
Well finally I managed to fix it, twice! here is the story.
After I left it for half an hour saying "Installing update 5%" I decided to reboot.
Tablet booted ok but there was problem with WiFi, couldn't switch to On.
I decided to reflash http://update.hicloud.com:8180/TDS/d...1LC100B206.zip once again but still nothing, I tried B002, B005 but no success with the WiFi (this wifi problem is something I did when I was fing around at the bootloader with fastboot).
Then I decided to flash the SimplyGoogle, that got me in a bootloop.
Ok I said now I will fix it once and for all.
Then I entered TWRP, wiped EVERYTHING and I got this http://update.hicloud.com:8180/TDS/d...1LC100B206.zip uploaded to the /sdcard/dload.
Next step was fastboot mode, flashed BOOT.img, System.img and recovery.img from the extracted UPDATE.APP of the M2-802L once again (keep in mind I have the M2-801L).
Now it was time to poweron with + and - pressed so the recovery to understand I need a system update/flash.
Again it was stuck at 5% but now I knew just left it hanging for an hour and rebooted.
And it worked.
At this point I want to give a big thanx to beast.in.black for his awesome instructions for how to recover a dead tablet.

You're welcome, glad I could be of assistance
Your posting of your experiences may help someone else who runs into a similar issue, so thank you for taking the trouble to post in detail :good:
Im afraid I am not quite as advanced as your self, I dont know what a 'META-INF directory inside and UPDATE.APP' is so please bear with me, especially if im preaching to the converted.
My problem was that I had a, basically, blank device.
The only thing that remained was the boot and recovery.
The first thing I got wrong is that the device is partitioned into multiple parts, its not one rom image for it all thus flashing a update rom wont write over all the partitions to recover the device, it will only flash the ones its updating thus you need an image that has alll the partitions to recover from a wiped device.
Second problem I has was that the TWRP recovery will not allow flashing of complete roms and I didnt have a backup of a complete rom.
Third problem I had was getting a hold of a 'complete image'.
So the link above allow you to download a complete image. part1 done.
then extract the boot partition from the complete image as the complete rom will only install/boot from its own boot partition: you cant install a complte from from a TWRP partition.
flash the bootimage from the complete rom.
copy it to the SD card, install it from there.
Then, once you have your system up and running, install your updates ot get the unit back.
Hope that makes sense and ive not just repeated things you already know, but thats as far as my knowledge goes

Blackview BV9000 Pro-F ROOT SUCCESS [TWRP + Magisk v16 + Stock Rom]

EDIT: included rough procedures for OEM unlocking, and updated link to recovery-verified.img (Sorry for uploading the wrong file ><)
Hi all bv9000 pro Users!
Recently I went on a journey to root this awesome rugged phone with one purspose: to remove that F*@(#&$ god awful loud annoying sound triggered by the OS when you use a camera app to take a picture + the boot startup sound (A bug blackview hasn't gotten around to fixing).
I successfully managed to port TWRP 3.1.1 from the Blackview bv8000 Pro and run it on the Blackview bv9000 Pro-f!
I've then managed to flash in Magisk to gain root access.
DISCLAIMER: I do not take responsibility for any bricked phones caused by the process, do so at your own risk (yadayadayada).
NOTE 1: Although I've got it running on the bv9000 Pro-F, this image should also work for the non-fullHD version, if someone can test this I'd be happy.
The link to the stock ROM (with the modified recovery img) can be found in the post below.
NOTE 2: No need to download anything other than what I've listed, Magisk is included in my custom recovery to circumvent the need to load the devices encrypted storage (or any other external storage) nothing stops you from mounting external usb storage.
What you'll need:
- USB Mouse (As there is no touchscreen input support, your device should have come with a usb-c otg cable so there's no problem here!)
- MediaTek SP Flash tools (I'd recommend the latest version) https://spflashtool.com/
- unlocked bootloader (You should be able to do this via the developer settings -> unlock OEM Bootloader)
EDIT: To unlock the boot loader, do the following:
1) Go to settings -> unlock OEM Bootloader (tick)
2) plug your device in (assuming you have ADB installed), use adb to access fastboot via. command prompt:
"adb reboot bootloader"
Then once the device is rebooted into fastboot mode
"fastboot oem unlock"
KEEP IN MIND THIS WILL REMOVE ANY FILES, so back them up
- I've done this with windows, but you should be able to repeat with linux no problems!
- A little patience
Pre-preparation:
First install any updates and back up your data (it's just easiest to use the google cloud backup as restoring becomes easy as pie, updating also fixes the setup wizard crashing on first setup). This is necessary because OTA updates cannot be performed with TWRP recovery, and flashing TWRP before doing OTA updates will flick the device into a recovery boot loop.
Install the SP Flash tools, and the MediaTek VCOM Drivers
(I won't link the specifics here, a quick google search should be able to help you, just note you might need to disable driver signature enforcement)
Two options for flashing:
1)
My Full Stock ROM already pre-prepared for flashing:
Patched ROM
No need for extra prep here! you should just be able to load the scatter
2)
My custom patched TWRP stock rom: recovery-verified.img
Blackiew's stock rom: stock rom
- Download the stock rom, backup the recovery-verified.img in the R06 folder, and then replace it with my custom patched TWRP stock rom (file name should be the same).
- Run "CheckSum_Gen.exe" once you replaced the file, it will generate the necessary checksum to allow SP flash tools to successfully flash recovery.
Once you've done with the pre-prep, switch off your device, take a deep breath and you're ready to go!
Steps!
1) Load up SP Flash Tools, select the android scatter file you've downloaded in the R06 folder
2) Select Download Only (I MEAN IT, FORMATTING WILL REMOVE YOUR IMEI AND RENDER THE PHONE USELESS)
3) Deselect everything but recovery (You only want to flash this)
4) Hit download
https://pasteboard.co/HkufwZZ.png
5) Hold volume up + power and plug in your phone, keep the volume up button held
6) very quickly the flash should be complete, and you should be greeted with a big ol' green tick to verify
https://pasteboard.co/HkuiTBB.png
7) Once you're done, remove your USB cable, plug in the OTG then we proceed to flash magisk
8) Hold power + volume up until you reach the bootloader, then use the menu to select recovery
9) You *should* be greeted with the TWRP recovery screen (Which is great success! )
DON'T PANIC IF YOU CANNOT USE THE TOUCH SCREEN, the kernel I've patched is missing this, seems the driver is different between touch screens, just plug in your OTG mouse to continue from here!
10) Use your mouse to first hit cancel, we don't need to decrypt the user data storage.
11) But oh no! it's all in Russian (no problem, Next step sorts that)
12) Use your mouse to navigate the menus as shown here to change to English! (or your preferred language) Change Language
13) Click install, then navigate up folder levels until you are in the root directory
14) scroll down and click on Magisk.zip, install it, allow it to install any apps as system apps (because this will then install to the system image, not the userdata)
15) reboot the phone (if it hasn't rebooted already)
16) You should be able to boot into your usual phones OS, if you don't see Magisk listed in your phone apps, just download it from here:
Magisk Manager
17) Congratulations! You should have complete root access :laugh::laugh::laugh:
Feel free to express your thanks, or list any problems you have, but keep in mind my studies take all my life, so I may not be able to help with all the problems you have
Congrats! Would it work on the BV9000 HD version?
Hi!
From what I've seen they both run the helio p25 chip
(Just a difference in RAM size) so it should.
You're more than welcome to try.
Just keep a backup of the original ROMs recovery. If something goes wrong during the boot to recovery you can easily re flash
hi i tried both optinos but they didn't work for me
I tried the first and the second options and it was showed me same error:
ERROR: STATUS INSUFFICIENT_BUFFER(0XC0010007)
I tried download only, format all and download, if i install original ROM its installing without problems!
In settings-> developer options -> OEM unlocking is enabled
can someone give me tips if I'm doing something wrong. thanks
My phone is Blackview BV9000PRO-F
Hello,
i have the blackview 9000 pro Hd (not full hd)
i first tried your prepared patched rom = not working (get erorrers in step 6)
then i chose step 2 and i was thinking to use the stock rom from the NOT full hd rom
now i get a green screen from the flashing: but after rebooting in recovery nothing happens, just normal reboot then
perhaps this is not so clair for me:
- Download the stock rom, backup the recovery-verified.img in the R06 folder, and then replace it with my custom patched TWRP stock rom (file name should be the same).
- Run "CheckSum_Gen.exe" once you replaced the file, it will generate the necessary checksum to allow SP flash tools to successfully flash recovery.
the file name you posted here " My custom patched TWRP stock rom: recovery-verified.img" is ramdisk-recovery.img
i replaced the ramdisk-recovery.img... it is not clair need to replace recovery-verified.img to?

Hi, you need to unlock the OEM bootloader, if this is still locked it will prevent the flashing of custom ROMS.
I might've missed this step, will update post as necessary.

Hi,
I've uploaded the wrong file, the uploaded file should be recovery-verified.img.
I'm uploading a new file and will correct the link now,
Please accept my apologies ><

I already did this step:
Enable developer options-> OEM unlocking is enabled
Is that enough for this MTK phone to be unlocked the bootloader ?
And tried the both options but the results are same.
I have been unlocking bootloaders on many phones but first time MTK phones. If i try with adb commands it recognize when is in the android with command adb devices and show my device but if I try reboot bootloader and check in device manager in windows its show its connected and drives are correct but if i try to show the devices, it doesn't show any device connected
Hi,
You need to install fastboot drivers once it's in bootloader mode,
then use fastboot, not adb.
"fastboot oem unlock"
Then follow instructions.
simply doing settings -> oem unlock won't unlock the bootloader, it allows you to do so later via. fastboot
Check the original post, I've added the extra instructions sorry about the confusion!
Thanks a lot. I finally succeeded to unlock the bootloader and root my phone and install the magisk.. I did without use your rom just I unlocked the bootloader and install your twrp file and after in the recovery mode i format the data and istall magic and i still have the last updated android.
I hope this it ill help to other people. Cheers

Congratulations .... I need a tip,.
And, brother, thank you very much. Worked perfectly.
But first I would like to get you a tip ..
One of the main reasons I have done all this complicated process was to be able to disable the crap of the loud music that plays when the device is started.
I want complete silence at startup.
How do I disable this ****?

Hi guys, lemme apologize for disappearing, life and whatnot!
For those stuck in a TWRP boot loop, simply restoring the original recovery then restarting the phone will be enough to fix the problem.
(Actually you really don't need TWRP after the phone is rooted, maybe I should update the guide?)
Many Thanks
First off, thank you for your hard work. Loved the "**** it we have an OTG cable let's use it" haha. It works fine for me.
Second, do you happen to know if someone has ported Oreo on our bv9000 ? Or do you know of any ETA ?
Thanks again,
Cheers
Anyone tried on the BV9000 Pro? Don't think mine is 'F' OR 'Fhd'.... I must have first model brought out...
Ugh.. Windows and Drivers?!?!
I keep getting Driver not Recognized in Windows 7 Pro X86.
I installed the latest vcom/usb drivers, in legacy also. No Go.
I installed from several other sources the drivers, including the Automatic Mediatek driver install. No Go.
So if anyone has a tip for me, please let me know because once more Windows is proving itself ridiculous. I can't even get to the storage of my phone. Did something change with a Windows Update that it's not allowed anymore?
I put my BV9000 Pro in OEM Unlock and USB Debugging. I backupped everything. My phone is ready for it. It's as ready as Amy having coitus with Sheldon for the first time.

Doing the update second time is fine, and best way to restore full stock. But you needed to use Oreo version of no-check recovery and the Oreo partition to flash it to.
So if still able to get into twrp, can try with correct no-check recovery and correct partition it's flashed to.
Also
With multi tool , make sure you put check mark on emui 8. Up in upper right corner. That way it uses Oreo partition names and file not nougat.
The partition length over message usually means nougat file or partition name used on Oreo system

On the extractor app. On options tab uncheck the verify header option, it should extract then.
Then perhaps first do these three partitions.
Kernel.img
Ramdisk.img
Then
twrp_ramdisk or for stock use recovery_ramdisk

adb devices
adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1
adb shell am start -n com.google.android.gsf.login/
adb shell am start -n com.google.android.gsf.login.LoginActivity
pause
in fastboot type:
fastboot -w
after all it's works to me to bypass google account verification
and if now your problem is

So now is locked frp. Does phone have twrp or stock now.?
I think when you tried to install the oreo update for second time, you followed same tutorial as the first time. And that made you problem worse. The tutorial has you flash no-check recovery to 2 partition by block number. 22 & 29. On nougat that is "recovery" and "recovery2". On Oreo partion table it is "reserved2" & "erecovery_vendor"
I don't know how to fix imei. Have hope that if to ucan have a full ota install , maybe can be fixed.
There is available a "service rom" (used to fix most all problem) for Europe region with l21.
I can share link to site with service rom if you want , but I have not used it myself so not gonna be much help with it.
Link is to rusian language page. Google should translate for you.

in summery. because i have been going back and forth in multiple different groups, multiple problem, i cant remember it all.
you have broken system, from failed root attempt, followed by failed update.
device condition is as follows.
--system not booting
--stock recovery loads
--fastboot/bootloader loads, but is in frp lock status
options are limited, at best.
I think "dload" method with service rom is best.
other option is maybe paid service like dc-unlock. But I can recall some note on there service about frp-unlock, that can only be used on device with working system. (of course if was working system, wouldn't need dc-unlock)

what about the "about phone" screen
what does it show for version?
If is all stock you should be able to go into deveolper options and enable "oem unlock". If it is greyed out and cannot switch it. Try First to remove google account (all accounts ). and reboot. See if can change then. If not, try Second to do "fastboot oem relock [enter your bootloader code here]
after relock and rebooted oem switch should be enabled again.
****RELOCK IS ONLY ADVISED IF 100% STOCK ROM****
otherwise relock could make more trouble.
Still not sure how to get IMEI back even if unlocked frp though.

Hello I have a Huawei Mate-SE (with bootloader unlocked and rooted with magisk v16). I have been using the android custom rom RRO v6 (RR-O-v6.0.0-20180401-bnd-OpenKirin) for around a month now. I got this exact same problem about the White Screen saying "ERROR MODE Attention...." since I updated the Magisk to latest version (from the installed application) and rebooted my phone. SInce I rebooted I am getting that same error which makes the phone loops into it for a few times and then it loads the Huawei eRecovery that offers me some options that I am not sure what would do to my phone.
I have been trying to connect to adb tools/fastboot but it doesn't detect the phone and im pretty sure I have the device drivers installed on my computer since nothing have changed in my pc for a month now since I flashed RRO on it.
Is there any other mode besides recovery that would allow me to connect adb/fastboot to it? Or does anyone knows how should I proceed?

I have seen where the magisk update screwed up and patches the kernel intead of the ramdisk.
Power off , long press power button.
Hold volume down and plug in USB from PC.
This should cause it to boot into fastboot mode.
Then flash the stock kernel. And the stock or first patched ramdisk. (From earlier root)

Hi thank you I was able to finally detect the device now. I am unsure about the kernel is that the recovery.img or system.img files I downloaded (i saved every file i used when I installed the rom) or do I need to look for the kernel somewhere else? I do have the complete_twrp_ramdisk.img file though.
Edit, I did more research and found the stock kernel is withing the boot.img file which I dont have so I looked up for the official BND-L34 oreo update and im currently downloading to extract the stock boot.img from the update.zip and flash it. Since that download was going to take me a while anyway i tried flashing the twrp recovery file without success (didn't changed anything) so i guess I should follow the instructions you gave me by flashing the kernel first then the twrp recovery.

if you were on oreo. then there is not a boot.img, instaed there is seperate ramdisk.img and kernel.img.
i have all the files already extracted for oreo and a backup from nougat as well.
https://androidfilehost.com/?w=files&flid=265998
make sure you know what you are doing before flashing.
for example. on oreo the boot and recovery share one kernel image. SO if kernel is messed up you will not be able to boot "boot" or "recovery"

GUIDE: How to unbrick your Zenfone 6 (ZS630KL)

Hello.
This guide will help you unbrick your device in case your devices hangs as it boots, and always boots into fastboot mode and recovery is unavailable and the like.
Note: Unlocked bootloader is not required to do any of the actions described in this guide.
Disclaimer: I'm in no way responsible for the actions you perform and whatever happens to your device due to these actions. Proceed at your own risk.
Prerequisites:
Service firmware. Can be downloaded here. It's an older build, but it will do the trick and it's the only one I could find freely available at the time of writing. Only for WW SKU
Zip for your desired build. Can be found here.
- Note: For this guide, my desired build will be WW-17.1810.1910.63, which is a special case, as you will need to flash in the following order: Service Firmware -> WW-16.1220.1909.194 -> WW-17.1810.1910.63. In other cases, unless noted otherwise in a description of the build on the ASUS website, Service Firmware -> Desired build will suffice.
Platform tools of Android SDK. Latest package can be downloaded from: Windows | Linux. Somewhat optional but good to have.
Step 1 - Preparing the environment
This is not required but for the sake of simplicity and keeping everything in one place, create a folder and name it whatever you like, for example ASUS or Unbrick
Create a sub-folder inside the folder you've created in the previous step, call it service_firmware, download and unzip service firmware into this folder
Download files for the desired builds from the above link. For this specific case, WW-16.1220.1909.194 and WW-17.1810.1910.63.
3.a If you have microSD card, transfer zip file for the desired build into its root and insert the card into the phone.
3.b. If you do not have a microSD card, download and unzip platform tools mentioned in the prerequisites as you will need adb to flash firmware/s via sideload
Step 2 - Flashing service firmware
Connect your phone via USB
Enter fastboot mode via one of the methods:
1.1. Turn off your device, then turn it on while holding down the power and volume up buttons at the same time. Release the power button when it powers up (keep holding the volume up button)
1.2. If you have platform tools, you can do adb reboot fastboot
Open CMD (windows) | Terminal (unix)
CD into the folder with service firmware from item #2 from the step above.
Make sure your phone is detected by typing fastboot devices
Ensure battery is at least 20% charged. Aside from normal means, it's possible to check the battery charge via fastboot oem get-batcap.
Sample output: (bootloader) bat cap = 35, which means that the battery is 35% charged.
IMPORTANT NOTE BEFORE CONTINUING:
By default, flashing with one of the scripts wipes your userdata, in other words, it performs a factory reset.
It is possible to avoid userdata wipe (although not encouraged) but keep in mind, unless you flash your current build after flashing service firmware, your phone will not boot up.
If you absolutely would like to preserve your userdata, even if for the sake of backing it up before doing a factory reset, you have to edit the flashall script in the following way:
Windows: Open flashall.cmd in your favorite text editor, go to line #298 and change it from fastboot -w to REM fastboot -wand save the changes.
Unix: Open flashall.sh in your favorite text editor, go to line #275 and change it from $fastbootcmd -w to #$fastbootcmd -w and save the changes.
Once again, this is not encouraged as it can potentially cause issues later on. You've been warned.
Run the script
1. 1. Windows: In the CMD you opened earlier, type flashall.cmd
1. 2. Unix: In the Terminal you opened earlier, type ./flashall.sh
Note: An obvious note, do not disconnect your device from your PC while flashall script is running. Your device will reboot a few times during the execution.
Once script outputs format logdump... and the phone reboots, service firmware will be flashed.
Step 3 - Upgrade to your desired build
Enter Recovery mode via one of the following methods:
1.1. If your phone is turned on and USB debugging is enabled, use command adb reboot recovery
1.2. While in fastboot mode, navigate to Recovery Mode using Volume Up/Down buttons and select with a single press of a Power button
1.3. While in fastboot mode, issue one of the following commands : fastboot reboot recovery or fastboot oem reboot-recovery
Once in Recovery Mode, you have 2 ways to proceed:
A: Update from SD card
A.1. Select Apply update from SD card option
A.2. Navigate your SD card and select UL-ASUS_I01WD-ASUS-16.1220.1909.194-1.1.1-user.zip
A.3. Confirm your choice with a single press of the Power button
A.4. Once you're back to the menu of Recovery Mode, reboot by selecting Reboot system now and enter Recovery Mode once again via any of the above methods
A.5. Select Apply update from SD card option again
A.6. Navigate your SD card and select UL-ASUS_I01WD-ASUS-17.1810.1910.63-1.1.1-user.zip
A.7. Confirm your choice with a single press of the Power button
A.8. Once you're back to the menu of Recovery Mode, select Reboot system now
B: Update through ADB Sideload
B.1. Select Apply update from ADB option
B.2. In your CMD/ Terminal, issue command adb sideload "UL-ASUS_I01WD-ASUS-16.1220.1909.194-1.1.1-user.zip"
B.3. Once you're back to the menu of Recovery Mode, reboot by selecting Reboot system now and enter Recovery Mode once again via any of the above methods
B.4. Select Apply update from ADB again
B.5. In your CMD/ Terminal, issue command adb sideload "UL-ASUS_I01WD-ASUS-17.1810.1910.63-1.1.1-user.zip"
B.6. Once you're back to the menu of Recovery Mode, select Reboot system now
Note: Like I've mentioned earlier, these steps are specifically for build WW-17.1810.1910.63. If your target build does not require another build for an update, you can skip steps A.4 to A.7 or B3 to B5
That's pretty much it. If you followed the steps above correctly, you should once again have a running phone with your desired build of firmware.
If you have any questions, do not hesitate to ask.
Cheers.

Thanks a lot mate, you made my day!
Please, one question: can you tell me, if both slots (A & B) are flashed by this method?
Thanks!
Thank you so much!
I've wanted to go back to stock for so long, but I haven't been able to find a stock ROM. I've even contacted ASUS support and they couldn't even get it! Thank you so much for the download and for the guide, you've made my week. I'll be smiling every time I use my phone thanks to you!
Great guide. I have a soft bricked device after flashing Lineage 16.0 recovery. Have a boot loop and can't get to recovery. I realise the mistake was flashing the recovery as should have just booted it.
Has anyone else had success with this on a Zenfone 6?
For those who need it; managed to resolve by downloading the stock firmware from Asus, extracting the boot.img and flashing it. Back working.
Didn't try the guide but this is quicker in this scenario if you have flashed a custom recovery to the boot partition. There is no separate recovery partition so this soft bricked the device, overwriting boot with recovery (I followed the guide here for LineageOS which is ill advised) . Should be booting the recovery rather than flashing, or booting into stock recovery and using the installer zip for your custom recovery.
Steps to recover:
1. Download stock firmware from Asus - make sure you use the same firmware version installed on the device or you may find it will boot but some hardware such as WiFi or others may not work.
2. Extract the archive and then you need to extract the boot.img from payload.bin - see this article and use the payload dumper
3. Flash your boot.img with fastboot flash boot boot.img
4. Reboot
Device should restart and boot up. Now to see why TWRP and LineageOS custom recoveries won't boot.
Hi, I followed your tutorial down to the letter, but when trying to install the ROM from stock recovery, I'm getting this error
"Eackage is for product ASUS_I01WD but expected WW_I01WD
Installation aborted"
Any fix? I'm trying to flash the latest Android 10 rom, but no luck.
This worked for me, but I'm still in CSC FastBoot Mode and when Android boots, I'm asked to insert a previous pin, which nothing works. Any advice?

Try flashing latest image of Android 9 and then flash Android 10
Can somebody please help me with my problem?
So I was able to get my hands on a new 8gb/512gb matte black version of this. Was setting up the phone, updated to Android 10 first before transfering sms, call logs and updating apps. Went to turn off the phone to insert my SIM card and now the phone won't turn on. It vibrates every time I press the power button but then nothing. Currently it's connected to the supplied charger with the LED light lit red. It was already charging while I was using it, had about 70% battery before I switched it off. I've tried volume down + power button for 10 seconds, LED light turns off and it vibrates, and it keeps vibrating every 10 seconds when it's connected to the charger (doesn't keep vibrating when it's not connected). Can feel the area between the fingerprint reader and camera pretty hot during this. Volume up + power doesn't work either. Any ideas?

Also, the phone gets detected when I connect it to my laptop but I can't do an "adb reboot" or "adb reboot fastboot" as it says the "error: device is not found."
I left it on charge overnight and the LED changed from red to green too.
Any help would be greatly appreciated.

When you connect it to your laptop, go to device manager and check what it is detected as.

I thought it would've been listed in the Ports section but it's right at the top under "Android Device" as "Android ADB Interface". I believe I have the correct Qualcomm drivers installed.
Attached screenie also shows device not found when I try an "adb reboot" in command prompt.

Hmm, I half expected it to be listed as QDLoader 9008, but then it would be under serial ports.
Try fastboot commands instead of adb and also try holding power + vol down for 10-15 seconds
Great guide @_Kuroi_ , I will be trying it out soon. The service rom you are using is pretty old. So I grabbed the last P update service firmware (WW-16.1220.1909.194) and the latest Q build I could get currently (WW-17.1810.2002.133). I have a subscription to one of the paid firmware sites for reasons like this. This way people have more options and it will simplify most people's updating because they can go from the new P service rom to any Q ota. Q firmware doesn't really make sense until it's not being updated anymore but it's here just in case someone finds it useful. If there is some incompatibility in the future or something that requires a newer update I will grab it then. If there isn't I will grab the last firmware once Q is stopped being updated.
WW-16.1220.1909.194
Here
WW-17.1810.2002.133
Here
WW-17.1810.2009.176

Feel free to update your guide to incorporate these all I ask is a credit in the OP for providing it.
After running ./flashall.sh I get the following output:

I don't seem to have a recovery partition by the end of it and "adb devices" doesn't show me anything.
Does anyone know what might have gone wrong?

unbrick Nokia 3.2

Hello together,
after many tries to get my nokia 3.2 rooted, i end up now with a black screen.
Only the Qulacomm mode is working.
Get anyone managed to flash the stock firmware with QFIL provided from the rooting thread?
I always end up with "sahara fails".
Every help is welcome!
Thanks!!!!
After many tries I have finally put my phone back to life.
My instructions how to do it will come soon!

please do, i encountered a similar problem.
HowTo Flash STOCK 00WW
1. Trigger nokia 3.2 to edl-mode (https://forum.xda-developers.com/nokia-3-2/how-to/guide-how-to-trigger-nokia-3-2-to-edl-t3962841)
2. Flash the given image from this thread (https://forum.xda-developers.com/nokia-3-2/how-to/rooted-nokia-3-2-t3945206)
- This was the main problem. I never managed it to flash the image with the Windows Programmer QFIL. After more research in Internet, i found finally a Linux application called QDL that work directly without any problems. This application can be found here https://www.96boards.org/documentation/consumer/guides/qdl.md.html .
- Flashing the software ends up into a bootloop. Also i got a message on startup that the bootloader could not be trusted anymore. After a software-update, this message disappears.
3. Flash all the user images again manually with fastboot.
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash system system.img
fastboot flash vendor vendor.img
flastboot flash vbmeta vbmeta.img
Whyever you have to flash this partitions only to the active partitions without the suffix _a or _b.
Then the bootloop is finished.
The phone boots normally to Android ONE.
The next problem which occurs on my phone is now that it is not able to connect to GSM network. I guess this happens because i deleted all the necessary partitions for the modem (modemst1, modemst2, fsg).
I get it managed to restore the imei, but still no service available.
In original my phone had the software 00EEA. Perhaps they use different drivers. My luck is that i got a cheap damaged phone from ebay with that firmware.
My next step is to modify the code from QDL that it can read the partitions from the damaged phone and save the software to computer.
Then i will flash this software to my phone and look if this software will run on my phone!

Thank you for your reply, it seems that your problem is more complicated than mine.
I have a global variant with 00WW software and i attempt to root the phone. I successfully flash the patched boot.img and had root access. However wi-fi didn't work after that.
Since before flashing the patched boot.img my phone was running on a different firmware from the one that boot.img was extracted from, so i think that was the problem.
I attempted to use QFIL to flash my phone back to 00WW_15 and it failed half way, bricked my phone.
Normally you can use the EDL Mode every time.
My phone only showed black screen and it was always possible to connect in EDL Mode and flash again.
Did you try to flash again? What happens then?
Flash the given image from this thread (https://forum.xda-developers.com/nokia-3-2/how-to/rooted-nokia-3-2-t3945206)

What did you mean by Flash the given image ? Was it flash the firmware package with QFIL ?
My main problem is flashing, it always failed half-way and the error log reported that needed files were missing from the package.
Okay. I used the linux program QDL for flashing.
But i saw, that in the xml file rawprogram0.xml a few files are missing.
The linux programm jump over these files but perhaps QFIL do not.
For example is there a picture.img listed which is not available..
Try to remove them manually from the rawfile and test again.

Hello,
my nokia 3.2 europe variant wont boot up its stuck in fastboot mode. What can i do to bring it back?
I get this: FAILED (remote: partition table doesn't exist)
P.S. if i do a fastboot reboot it boots back into bootloader
I also had this problems for many many times and don't know what went wrong when this happens.
The only thing that helped was flashing the complete firmware again in EDL-mode.
You can try first to flash only the 5 user-images with fastboot, which i mentioned before in this thread.
I uploaded this files for you, because you don't will find the europe files in internet yet.
Here is the link:
https://transfernow.net/81iti7q21s0s
Good luck!
Hi,
Thank you very much. Is this the complete Firmware? (All Images from Device) Another question: I couldnt Access the recovery System. Did you have the same Problem when your Nokia didnt boot up and was stuck in Bootloader? So is this normal that the recovery is unaccessible?
Yes, that also happens sometimes with my phone.
No, that are not all firmware files, which you need to do a full EDL-Flash.
But with this files you can first try a fastboot flash!
If it does not work, you can take all the other files from the Global-Stock-Firmware, given in the thread https://forum.xda-developers.com/nokia-3-2/how-to/rooted-nokia-3-2-t3945206.
Delete the 5 files with the same names, flash the Global-Stock-Firmware in EDL-Mode, with QFIL or QDL, (without the 5 files) and in the following flash the 5 europe-image files with fastboot.
Thanks, ive sent it in and got Friday a 00WW Variant of the device back. I will upload those User images for 00EEA to my Google drive so that anyone who needs those files can download them
