[Guide][Tutorial] Root TWRP LG G5 using Autorecowvery[H830 & V20A only][Noobfriendly]
This is guide to root and install twrp on lg g5 T-Mobile using recowvery method.
Read 4th post before proceeding​This method is to root & install TWRP on only T-Mobile LG G5 running Nougat 20a software. If your phone isn't on 20a then first downgrade/upgrade to 20a software.
Before asking a question, first, see FAQ in 3rd post. In that way you can save a lot of time.
For Video Guide refer to 5th Post
You need to disable antivirus before extracting files. Because we are using DirtyCow vulnerability here. Which is technically a virus (It's not dangerous for pc but for exploiting android to get root access). If you can't disable AV then don't proceed because process will not work
Download:​1: Recowvery (2nd post)
2: Minimal adb (2nd post)
3: TWRP
A: H830 | For H850 (Refer to this Post and read carefully)
[Download TWRP 3.0.2 as 3.1.0 is having some little issues with flashing with autorecowvery] Always download latest TWRP available for your device to avoid most issues.
(rename it to recovery.img)

Procedure:​Drivers should be installed. Also install minimal ADB and fastboot.
1: Make sure to unlock bootloader. Backup internal data because it will be erased.
A: First enable developer options and toggle “Enable OEM unlock” to ON. Also enable “USB Debugging”.
B: Run Minimal ADB and Fastboot. Enter Command
Code:
adb devices
C: You will see permission dialogue on phone. Tick “Always allow” and ok.
D: Now enter.
Code:
adb reboot bootloader
E: Now phone be in fastboot mode. Enter
Code:
fastboot oem unlock
F: This will wipe all data on internal storage. Now Enter
Code:
fastboot reboot
G: Now OS will get booted. Bootloader will be unlocked but phone should be in factory reset condition. So again enable “USB Debugging”.
THEN​
2: Connect phone with pc in MTP mode and copy recovery.img to phone’s internal storage (Make sure to select MTP as always to avoid problem during procedure). Extract recowvery software. (If it causes permission problems extract it to USB device and perform process from there)
3: Run “EasyRecowvery.cmd”. Press “5” -->Enter then press “7” -->Enter to disable integrity check. Then enter “0” to go back. Skip it if you are using Recowvery G5 modified.
4: Now press “2” and wait until it says warning. Press “y” -->Enter. (It won't say warning in Recowvery G5 modified)
5: It will do rest process. After Flashing TWRP it will flash “no-opt-encrypt” (This is most important to save twrp from being removed by OS)
6: Phone will boot into TWRP. Here on phone it will ask for decrypt code. Cancel it. Swipe to allow modification.
7: On pc press any key, the flashing process on phone will automatically get started. Then it will reboot into OS.
8: To flash supersu, select option 3 from recowvery windows and phone will boot into twrp. Same as step 5-6 it will automatically flash supersu.
Now Your rooted and have twrp install.
Note: For removing Encryption.
To flash a custom rom and remove encryption in twrp, you need to once format data in twrp else you won’t be able to wipe and install any custom rom in your phone.

Recowvery G5 modified is fully working, so you can try it.
I'm still keeping easyrecowvery 1.3 in this thread as a backup plan.
Read Read Read Before using This
Test Version --> Ricksy-Recowvery | Mirror
(Ricksy Recowvery is streamlined, checks free version of EasyRecowvery. It has no unlock checks, no model verification so use it only if you're fully sured about what you're doing. It includes but isn't limited to unlocked bootloader, USB Debugging Enabled, Being on V20a firmware, LG Drivers installed, PC allowed as Trusted in USB Debugging as always)
Remember to copy latest TWRP to root of internal storage as recovery.img before proceeding.
Old Test
There is also Addition of Recowvery G5 modified 2.0 Test version as well (This script has some additional features)
(I have also turned off most security checks, so you should have an more easy rooting experience. However, this increase risk of bricking device if you do not read things properly). If you can provide your experience of using this script please share your knowledge.

FAQ​
Recowvery tool is causing permission errors when I run it through computer's internal HDD storage. What shall I do?
Ans: There are possibly 2 workarounds for that.
A: Extract the zip to external USB storage and Run the tool.
B: Change the name of folder, in which recowvery tool is, to "1" and copy to root of storage e.g. "Computer:\D:\1".
Can I re-lock my bootloader after rooting and TWRP flashing?
Ans: No, as recovery partition modified now, this will brick your device.
Can I use V20C or later on my phone after rooting and flashing TWRP?
And: You can't take OTA after rooting as this might create a brick but fortunately @autoprime created TWRP flashable zips of firmwares e.g 20c,20f,20i and he might create newer builds too. Anyways here's the Auto Prime's thread, Go to "LG G5 Files" link and download file as per your variant and choice.
I bricked my phone after following this guide and now I can access only download mode, what shall I do now?
I'm on other version than 20a, What shall I do?
Ans: Really? It seems like you're kidding because this guide can never harm your device, It can either do it's work or not but there is no way for it to brick a device (Unless you don't read carefully).
Ans: You can take your phone back to v20a by using the following guide.
Anyways​You can always bring your phone back to life by following this Back to Life thread.
How to remove encryption in TWRP? or I'm unable to access my phone's internal storage from TWRP, What shall I do?
Ans: So for this process.
a: Boot into twrp.
(you can boot to TWRP by any app or by vol- and power button combination or from option “5” --> “5” in recowvery toolkit (command window).
b: In TWRP, cancel code Windows, Swipe to allow modification then
Click -->Wipe-->Format Data-->type “yes”-->enter.
You need to do this only once. After that you can flash roms and zips unlimited times.
Will this root method work on 20c/d/e/f or others?
Well, it shouldn't. Because I tried this on 20c and it never worked, so I believe it will not work on any software other than 20a because LG removed that exploit to root after 20a. But you can try your luck and tell me if you succeed.
a: Thanks a lot i have one lg g5 h830 and i have some fear to lose the unlocking and i want to modify the phone.
b: Same i have anyone please answer it will i lost the UNLOCKING (Modified by shopkeeper) if i FLASH another ROM?
What are you people trying to ask here?
Bootloader Unlock:
Bootloader can be locked and unlocked anytime you can to do so just by typing commands in fastboot mode. In T-Mobile G5 the fastboot mode do not accept flash command that's why we can only lock and unlock bootloader.
TWRP:
As commands are limited in fastboot mode of T-Mobile G5, we are unable to flash twrp through fastboot mode. So, for this process we rely vulnerability found in G5 firmware. The only currently found method for doing so is by using dirtycow exploit to flash TWRP on H830. Only V20a contains this vulnerability to do so.
Summary:
So to flash TWRP and enjoy freedom of using custom rom (Which I suppose you refer as Unlock to) you need to be on V20a. Which can be flashed easily through LGUP with Uppercut or use my LG FlashTool method (Link in FAQ section). When on V20a firmware simply use this or your preferred method for flashing TWRP.
If you want to go back to stock, simply flash any stock KDZ and lock bootloader. If you want to get TWRP again, simply unlock bootloader and flash V20a kdz (or flash V20a kdz and unlock bootloader) then instal TWRP by using the process.
Important:
Currently our stock firmwares are running Anti-Rollback (ARB 01), LG can increment this whenever they want, whenever LG increase ARB to 02 or upper then you won't be able to get back to ARB 01 firmwares (e.g V20a ) again. Which means you can unlock bootloader but won't be able to flash TWRP as dirtycow is patched after 20a. So you will lose the ability to flash TWRP which means unlocked bootloader is useless unless someone finds another method of flashing TWRP.
So, if you want to stay unlocked, then make sure to install TWRP as described above and flash latest TWRP flashable stock base zips or use other roms like Fulmics or AOSP based. It's very simple and easy .

Nougat v20a only as the thread title says.

I had to extract to a USB device to get recowvery to work but it went smoothly from there, until I got to TWRP to flash the no verity zip. It hung on hit any key to continue, it didn't dawn on me till later I should have mounted USB storage (derp), but I already had the no verity zip and SuperSU on my external SD so I just flashed them manually, booted, and had root. Then I formatted data, lost root, and flashed SuperSU again to get it back. I later flashed @autoprime 20c zip with SuperSU and now I'm rooted with TWRP on 20c, tyvm for the tutorial

First of all you welcome, 2nd thanks for writing about your experience.
I am not completely assured but to make recowvery work in internal hard drive you need to change the name of recowvery folder to "1". Next time whenever you root try this method and let me know wether it worked...
And as you mentioned about having difficulty in flashing no verity. I think this issue is happening only on TWRP 3.1.0, on TWRP 3.0.1 it works fine, i think .

Does this method work with the latest update to 20f? Can I just try it without bricking my phone?

Thanks, I'll try that next time. I did use TWRP 3.0.1 though, but I'm thinking that without mounting USB storage, perhaps the verity zip couldn't be found to be flashed.

This worked perfectly!! Thank you so much again! I had to extract the recowvery to a usb stick and run it from there (it wouldn't run properly from the computer hd) and at first I got an error as I had put the recovery.img on the external phone sd. My bad. Anyway... I just copied it over to the phone sd and started over, and it worked exactly as explained in the OP.
AWESOME effort by everyone involved. XDA rules!
Btw... can I relock the bootloader now? And one more thing... I turned off "automatic system updates" in developer mode. I assume if I update to v20c or newer I will lose root? And I guess I should not update the supersu either?
Thanks again! You rock!!

As you installed TWRP, so recovery partition is modified which means if you relock bootloader, you will brick your device.
Also if you want to use V20c check @autoprime's thread for the TWRP flashable zip of V20c or later (if there any).
And if you want to update supersu you can do it either by newest supersu zip to flash it through TWRP or by updating it through playstore then update binary through supersu it self, but I think updating supersu mostly changes nothing.

Ok. Thanks for all the info. I think I will keep the v20a with the current supersu. It works perfectly! Hopefully it will not "automatically update between 23:00 and 04:00" as it says in "about phone/update center/system updates". From what I understand, it shouldn't as long as I have the "automatic system updates" set to OFF in developer options.
How can I boot into TWRP? When I reboot and try to enter TWRP I always end up in the hard reset menu where it asks if I want to wipe the phone... Do I have to boot into TWRP through ADB fastboot?

When you boot to recovery through hardware key combination, say yes through hardware keys twice (as you want to reset), it will take you to TWRP, thats the logic from lg g2

He is absolutely correct. That's exactly what I did on my H830 yesterday.
Keep up the great work people......

Got it after a few attempts
Thanks for the step by step. It is a good walkthrough for a tough device. With all the previous complicated, and sometimes confusing/conflicting, instructions in other (older) threads for the H830 I was nervous to try.
I struggled a little getting it to work; 1) .cmd returned "don't have permission to create log or backup files..." when running from my "documents" directory, had to run it in a root folder. 2) I got the wrong TWRP version at first and the process said success, but never made it to TWRP.
It was the most challenging of any device I have owned to get root, but happy to crack it. Thanks!

Well, it shouldn't. Because I tried this on 20c and it never worked, so I believe it will not work on any software other than 20a. But you can try your luck and tell me if you succeed.

Salam bro,I followed your method and rooted the phone,after rooting I wiped system, data and cache so I could flash fulmics 2(based on v20c) which I had already downloaded,it flashed successfully but after booting on startup screen there's this popup error"settings keep closing " because of which I can't do anything so can u please tell me where did I go wrong,should I have wiped the system or not?

[FRP Lock] Need help to unbrick honor 7X (SOLVED)

Hi
After updating to EMUI 8.0 from this tutorial everything went well. Got Oreo working fine, so started to root with magisk = Ok; Xposed=Nok... Bootloop.
First - clean Data and Cache+Dalvik, still Bootloop
Entered to fastboot and tried to flash this file to rollback to 8.0, but...
I nottest that it said on the screen:
Bootloader UNLOCKED (in RED) and FRP Locked (In Green)
Confusing colors, cause it seems that i can't flash anything with unlocking the FRP... but i don´t have access the the system....
Also cant format System partition cause its read only, unable to flash other recovery files thought fastboot....
It s a f*cking MESS....
Can anyone please advice on this?
What can i do to recover this piece of sh*t??
Please........
Thank you, people

Long story short, i've solved it but have to pay for it.
Went to HUAWEI Service Center here in Portugal, and they told me that they couldn't do anything since the phone was not marketed for Europe (??????) [ASS Os]
I've discovered this service, and as with any other service online, i get suspicious for a while, asked a lot of questions and decided:
Bought a Month Pass for 50 EUD (45 Euros), and voila, in the first try unbricked the phone
Now i have the rest of the month to play with it...
Thanks for the people of FunkyHuawei for the kind attention (mostly pacience) they had with me.
I recommend it :good::good::good::good::good:

Do you still have access to twrp?
It could be only hope.
I had frp lock problem after unlocking bootloader. I had hit reset to default setting while inside developer options menu. That flipped the oem unlock switch.
I had to use twrp to flash back the stock boot.img and stock recovery.img then i was able to oem relock (my code).
And boot into room and reflip oem unlock toggle

thanks for replying
Not sure that i can access TWRP cause every time i force the recovery it appears the EMUI recovery (probably the NoCheck version that i used to update to Oreo)
Isn't it possible to reverte back to EMUI 5.1? Maybe with the 'dload' methode??
Is there any way to reset/unlock FRP from fastboot? I tried to relock bootloader with my own key but got an error (can't remember now what...)
I can't access the ROM itself...
This was because i installed Xposed....
If i could access TWRP again, perhaps i could delete the xposed files (in a recovery with the system as read-only)...
But i just dont know what to look for....
In older systems i knew that was the app_process file... Now i just dont know....
Thanks again for your reply!

Please can you explain that in detail?
Cause that might be the only way to save this (#"))&%&(/)&....
So, here is my situation:
- No TWRP access (recovery_ramdisk might be empty or damage... hopefully just empty)
- Bootloader Unlocked but FRP Locked
- eRecovery only presents 3 choices: Shutdown, Reboot and "Download latest version and recovery"*
- The System it self it's messed up after trying to install xposed.... just when its about to start, it reboots...
So.......
Still 3 ways that i can resolv this:
1 - the dload method (already tried, it updates until 5%, then error:" Install update failed" (Use the update.app file from the OTA, FullOTA, just the app file, all files in the update.zip... ) Not sure if i'm missing the right app file or if the eRecovery (maybe the NoCkeck version used to update initially) is screwed-up...
2 - Unlocking the FRP (Factory Reset Protection) this means that the "Allow OEM unlocking" is Off
Hopping to find a way to unlock it via fastboot
3 - The *Download latest version and recovery method allows to connect to wifi and download the firmware...
Not much sucess, but i know that i'm missing something (just dont know what it is...)
It seems that the router requires a certain configuration which i have no idea....
Suggestions are always welcome!
Thanks

What I'm trying to understand , is how were you trying to install exposed.
I assume it was with twrp, no.

theres not much to understand there....
i flashed it with twrp and the phone never booted again...
yes, had access to the twrp for a while, but then, trying to run again the update process to flash the wrong recovery to recovery_ramdisk partition.... (another shot in the foot)
now i dont have twrp anymore and i'm unable to flash it cause th frp lock keeps telling thats not allowed...
the most clean way to solve this is to erase/unlock the FRP without accessing the ROM...
I'm already thinking about buy some credits with one of those online services that might unlock it...
Can you suggest to me some serious and honest services?
I'm desperate....

Hi,

Honorable mod, I guess this thread belongs to Honor 7X Q&A forum. Please relocate.
Cheers

you cant downgrade from emui 8 you need to extract update.app of emui 8 an flash the ramdisk boot img so it will boot for that you need to download indian firmware mannual update given in other forum and extract the zip file update22 and data file extract both zip files and download the multi tool version 8 install all drivers boot your phone into bootloader now go to multi tool and click on unbreak and open huawie update extractor and extract update.app of data or update 22 make sure to check the mark on top emui 8 and when you click on update make sure to uncheck the verify the headder for that you go to settings in extracting update and follow the procedure of flashing for that you can google how to use multi tool i cant explain more i am not a developer but i phase the same problem and i got fixed hope i helped you

After updating to EMUI 8.0 from this tutorial everything went well. Got Oreo working fine, so started to root with magisk = Ok; Xposed=Nok... Bootloop.
First - clean Data and Cache+Dalvik, still Bootloop
Entered to fastboot and tried to flash this file to rollback to 8.0, but...
I nottest that it said on the screen:
Bootloader UNLOCKED (in RED) and FRP Locked (In Green)
Confusing colors, cause it seems that i can't flash anything with unlocking the FRP... but i don´t have access the the system....
Also cant format System partition cause its read only, unable to flash other recovery files thought fastboot....
It s a f*cking MESS....
Can anyone please advice on this?
What can i do to recover this piece of sh*t??
Please........
Thank you, people

Tried that but the only response that fastboot gives me is "Command not allowed" .
I just can´t flash anything in fastboot. I think i can thought adb shell dd (at least that how i manage to screw twrp partition), but i just can´t get ADB connection.
Just got fastboot connection with HiSuite drivers...
How can i get ADB access? It just installs an USB Storage Device...
Also i can try update via fastboot but it saying that it misses android-info.txt file.... whatever that means...
If i could boot once into the ROM, i would enable "Allow OEM Unlocking" and do exactly that.... btut i junt can´t... not yet...

you cant downgrade from emui 8 you need to extract update.app of emui 8 an flash the ramdisk boot img so it will boot for that you need to download indian firmware mannual update given in other forum and extract the zip file update22 and data file extract both zip files and download the multi tool version 8 install all drivers boot your phone into bootloader now go to multi tool and click on unbreak and open huawie update extractor and extract update.app of data or update 22 make sure to check the mark on top emui 8 and when you click on update make sure to uncheck the verify the headder for that you go to settings in extracting update and follow the procedure of flashing for that you can google how to use multi tool i cant explain more i am not a developer but i phase the same problem and i got fixed hope i helped you

That was my plan... but even that is screwed-up.....
Here is my Recovery Status, without the possibility to flash any img via fastboot:
recovery_ramdisk (empty or in-error)
erecovery_ramdisk ( BND-RECOVERY-NoCheck.img flashed to update into EMUI 8.0)
With the software now, whats failling me is the ****ing recovery, that flash only 5% before it shows this error : "Install update failed!"
Dont have ADB support, maybe because i dont have the "USB Debbuging" option enable...
It seems that i will spend 15 euros to unlock this &%/())(/&%$######()/=?(/%&$#

Just thought I'd post here in case you are still in need. I believe that there are two different recovery modes - one that is triggered by holding power, up vol, and down vol, and another that is triggered by holding just power and up vol. Are you sure twrp is gone? I thought I had lost twrp when in fact it was in the other recovery.

RSGI said:
Please can you explain that in detail?
Cause that might be the only way to save this (#"))&%&(/)&....
So, here is my situation:
- No TWRP access (recovery_ramdisk might be empty or damage... hopefully just empty)
- Bootloader Unlocked but FRP Locked
- eRecovery only presents 3 choices: Shutdown, Reboot and "Download latest version and recovery"*
- The System it self it's messed up after trying to install xposed.... just when its about to start, it reboots...
So.......
Still 3 ways that i can resolv this:
1 - the dload method (already tried, it updates until 5%, then error:" Install update failed" (Use the update.app file from the OTA, FullOTA, just the app file, all files in the update.zip... ) Not sure if i'm missing the right app file or if the eRecovery (maybe the NoCkeck version used to update initially) is screwed-up...
2 - Unlocking the FRP (Factory Reset Protection) this means that the "Allow OEM unlocking" is Off
Hopping to find a way to unlock it via fastboot
3 - The *Download latest version and recovery method allows to connect to wifi and download the firmware...
Not much sucess, but i know that i'm missing something (just dont know what it is...)
It seems that the router requires a certain configuration which i have no idea....
Suggestions are always welcome!
Thanks

Not even that i can do....
Let's update:
State
OS: Bootloop
System: No "recovery_ramdisk" partition (no stock / no twrp)
Bootloader: Unlocked
*FRP: Locked
So can't flash in fastboot, *Already got the unlock code for the FRP but without the "recovery_ramdisk" recovery the system wont reset....
(Weird!) No adb access in recovery mode (which would help A LOT....)
The dload method, whatever the update.app only updates until 5% , then error updating...
The eRecovery Wireless method might work, but i just dont know how to do it.
Tried with a usb pen inserted on the router with all the ROMs all together, in separated folders, whatever, no rom detected... there must be a way to do it right... i just dont know how...
Just need one of two things to happend:
Flash the stock recovery - still dont know how to do it...
Fix the bootloop and access the SO Rom - also, without adb access just dont know how...
Out of the box thinking required...
About UPDATE.APP
Can't we make a update.app much like o do it for zip files?
Would it be possible to make um UPDATE.APP just to flash/restore recovery partition?
The updates with zip files must also be inside a dload folder?
About Bootloop and SD Card
Is there a way, using the sd card, to stop the reboot, maybe enable the Safe Mode...
Something that would allowed me to access the Settings...
Any apk, any script that could be loaded from the SD card....
Not an easy plan... i know...
Maybe something very basic and easy is escaping me....

I just read through the fastboot partition from my backup using "strings" to find the available "oem" commands.
I think i found possible solution for you.
careful useing these commands as I do not know for sure if they work and what they do.
Code:
fastboot oem frp-unlock
also not sure about the dashes or underscores.

Hi
Thank you for replying.
Already tried that.... Actually the command should be:
Code:
fastboot oem frp-unlock (unlock frp key)
Bought the unlock code from an online unlock store.
Spent 10 euros. The code is correct cause i got the message that the device will reboot and do a factory reset.
Than it reboots into an error screen, cause i screwed up the "recovery_ramdisk" partition earlier and its not working now. So, no factory reset, no changing the Frp status... Still locked.
Still no flashing img files from recovery... Still got the reply oficial Command Not Allowed...
But:
I'm trying to gain adb access while on eRecovery.
Than i could try to flash the stock recovery with the code dd command. From there i would unlock the Frp with the code and the Factory Reset might be enought to fix the bootloop.
Also the bootloop it self...
I wonder if there's a way to force the boot even with FC errors....
Access to the ROM software would allow me to flash the stock recovery and then make a factory reset, by changing the OEM Unlocking status
Thanks for your reply, maybe you can give me some tips on this 2 ways that i'm exploring right now.
Or some other ways that i haven't consider yet... please....

BlackView BV9600 Pro + LineageOS?

Hi! Could you please explain if this ROM will be compatible with my smartphone? I'm not sure, I don't found it on the list on LineageOS website.

simply follow this guide -> LINK
- allow OEM unlock in the dev-settings (hit 5 times build number to see)
- allow usb debugging
- reboot to fastboot
- send "fastboot devices" command
- send "fastboot oem unlock" -> acknowledge
- send "fastboot flashing unlock" -> acknowledge
- flash the twrp image "fastboot flash recovery name_of_the_image.img"
- reboot into twrp by power of the device
- after that press vol+ up and power button (if i remember correct.. ) to get into twrp
- now u need a sd-card (micro) put no verity opt encrypt on it and magisk
- Backup all partitions u find.
- format data partition to get the size
- install magisk
- install no verity opt...
reboot
BV9600 should be rooted. Took me serveral times to get it working, because u need directly after "Flashing unlock command" to get the twrp stuff done.

First u need to go to fastboot mode, to unlock "OEM UNLOCK"
This is easy via adb
-> reboot fastboot
Did u install the correct driver? (ADB driver) is ur device listed?

i tried repacking it myself but with no luck so far, also tried various treble GSI, all booting on my BV9600Pro and basically working but mobile data and phone are broken so that's not an option for now

I don’t understand why unblock the bootloader at all if everything is installed on the MTK platform using the SP Flash Tool !?
Why these dances with adb and fastboot? if a everything is done much easier ...
You do not install the factory software using adb ? not ?? so why can't TWRP be installed and installed using the SP Flash Tool!? Why complicate things?

Root with sp Flash tool
Hi please Anyone could explain this procedure with Sp Flash Tool and post it?

Because the vendor (Blackview) locks the bootloader (like any other brand does) and does not allow installing any other recovery without it.!?

Is this a statement or a question? Sorry, I do not know English and I use a translator ..
II repeat once again, in order to install TWRP you do not need to unlock the bootloader!
it installs without problems using the SP Flash Tool
and this is not an assumption but a statement!
My first copy of the smartphone received TWRP. It was on my copy that all the first tests of TWRP and ROOT were conducted.

I'm glad to hear that it works that way to you. But that doesn't worked for me. So i wrote the way i took, to root. Let the others choose, wich way works for them. :fingers-crossed::good:

I am using another MTK device and SP FlashTool is great it lets you recover from any software brick. So I will advice people to use this method.
I am planning on buying bv9600 pro and having twrp ported and root is a good start to custom roms.
The touch driver issue on twrp should be easily solved with the good kernel module for the twrp. And official twrp support would be nice.
Subscribed to the thread will see where it goes.

hi guys, can you share a clean system twrp backup of bv9600? because my USB is damaged and i can not use sp flash tool to clean restore. thanks!

Hi, i try to root my bv9600 pro, but all i end up is on reboot the system restores to factory no TWRP or anything on it. I connected it to MTKdroidtools and it complains about a file /system/recovery-from-boot.p which restores recovery and obviously after it the system too.
Thanks for any help
edit: LOL nevermind, working fine now, don't know what was going wrong, in a last try just downloaded the latest stable magisk again. Thanks AMDFenics for the howto
Just one thing, can i get rid of this 5 sec. warning that the mobile is unlocked?

Stuck in Bootloader Fastboot Mode

Dear All,
I was trying to install a customer ROM in my Asus Zenfone 5z. I was able to unlock the bootloader using official asus app. Then i managed to install a TWRP recovery. there was some partition issue so i flashed recovery in both partitions. the recovery worked fine and i managed to install the pixel rom. after that i wiped dalvik cach and some other items throgh recovery and restarted the phone.
After restart, it is stuck in bootloader. If i select start, recovery mode or power off, it gets rebooted and come back to bootloader again. Seems like a brick scenario.
So i tried the following:
1. Downloaded AFT tool and tried to flash the latest firmware version.. It gave a FPT error and then error on unable to load into recovery mode
2. Tried to run flashall_aft.cmd in directory containing latest firmware.. it said to internal/external command exists
3. Sideload using adb sideload command.. the error was could not read the file..
I am not sure what i can try next.. could you please help.. The details on bootloader screen are:
Fastboot mode
Product name _ ZS620KL
Bootloader version - WW_user_90.10.138.157
Secure Boot - yes
Active Slot A
Device State Unlocked

Help Required - Soft brick - Stuck in bootloader

Download qfil,
Scrap fz*.mbn from CSC_8.02 and put to raw file of your interest. Ifu don't do so, it will throw error as that file is required and only available in CSC_eng_8.02 version. Never ever touch any other file in CSC 8.02 , it will make it impossible to run any fastboot and adb command and entering EDL is a bit tricky.
Extract the firmware, make sure to have system,vendor,userdata in root path as if u don't remove last few line of Python extraction code it will be deleted.
Go to TWRP Recovery, and reboot to EDL from there.
select all raw program XML and Patch xml and begin Image download.
Doesn't matter whether anything is accessible or not u get new image of ur choice.
If u get sahara error you are not immediately beginning download as ur phone enters into EDL.
Suggestion: Once u get back image sell the [email protected] quarter of cost as it's impossible to run the device in the way you want. The tools are not supported for open source development. The device is fragile, a little tweak and you lose IMEI,SN and soforth your phone network. This is not a device to temper, if u still do so, you will never come out from situation your stuck now.

Iam able to flash latest firmware by connecting to PC in fastboot, all files are able to flash and after restart, a message is appearing with red exclamatory symbol that my device is no longer boot, its not trustable etc and after few seconds restated to fastboot mode. I have tried this in both active slot A and B. I tried to flash android q image too. same error popping up. and iam struck in fastboot now, no recovery nothing, phone doest even switched off, if i longpress power key, restarts again to fastboot.

Your bootloader is relocked, and vertified boot is enabled, if I had not misunderstanded the information you have given. Try unlocking your bootloader first.

Your bootloader is relocked, and vertified boot is enabled, if I had not misunderstanded the information you have given. Try unlocking your bootloader first.

Installing Custom ROM on Cubot KingKong Mini

UPDATE 2021
The original post was for the first King Kong Mini, for instructions for the King Kong Mini 2 go to page 9 in this thread:
https://forum.xda-developers.com/t/...-on-cubot-kingkong-mini.4050815/post-84445303
======================
The Cubot King Kong Mini was released in Q4 2019. It is one of the smallest Android phones on the market with a 4" screen. Like many cheap Mediatek devices, one cannot be sure of how "safe" or "secure" these devices are, so the security/privacy conscious may want to consider installing a custom ROM. Here are the instructions for installing Android AOSP on the Cubot King Kong Mini. Note: I am not responsible for any bricked devices.
Download the Stock Rom from here and SP Flash Tool just in case you need to reinstall Stock. Download a system image, note you need to use an A/B arm32 image with 64 bindings. For example AOSP 9 is here.
This process probably can be done with SP Flash Tool but I wasn't able to manage it due to the disable-verification flag required.
Unzip the stock ROM and reboot the device to bootloader, connect via USB and unlock via:
Code:
sudo fastboot flashing unlock
Note this will erase all data. Then on your computer navigate to the folder with the unzipped ROM (for me was NA_mt6761p_d936p_9101cmp_chuanqi_cc_256gbitp24d3_p_lte_3m-fdd-cs_mul_20191121-210020_songlixin_PC) and type
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
If you do not do this it seems to work without it but then it will bootloop when you try to switch it on. From here on it's standard.
Code:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
Unzip the .xz image file you wish to use and type:
Code:
fastboot flash system SYSTEM.img
where SYSTEM is the name of whatever image downloaded.
Root
For root install magisk manager and you have to patch the recovery to get root (not just boot as flashing boot alone doesn't give you root). So in magisk get it to patch you boot and recovery images and then put those on your computer, go to bootloader and use:
Code:
fastboot flash boot magisk_patched_boot.img
fastboot flash recovery magisk_patched_recovery.img
You can read more about magisk from recovery here.
To get root then you need to reboot to recovery, hold power button + volume up and select Recovery. This will appear to boot as normal but you will have root when you do it this way and not when you boot normally. Unfortunately I do not have reception when I do this but do have root, other users have this problem but I have not found a solution.
Note that I thought I bricked my phone a few times before getting this as nothing would happen after a failed boot and I couldn't switch it on, however what happens is you can't do anything until the battery has almost completely discharged, then when you hit the power button you'll get the no battery sign and when you plug in you can get to Recovery again. This is quite annoying if you've charged it quite high as you'll have to wait a long time to discharge and be tapping on the power button a lot!!
What doesn't work
Battery usage doesn't work, this can probably be fixed following this guide. If I get time I will attempt this.
Other things to note, there is no TWRP yet so I don't have decent recovery options, this also makes it harder to use certain ROMS as you can't flash things like gapps if you install a ROM without it.
The battery life is definitely worse using AOSP GSI than stock, maybe that vendor overlay would help with that though.
I hope that helps others.

TWRP+Encryption Disabling+Magisk Root
Actually there is TWRP for this model ported from alcatel by NickyNS. You can pick up it from here.
You can flash it with fastboot along with the patched lk which is to disable the "Orange state" message. After flashing it you should enter TWRP right with the next step (without booting to OS). On this stage you might want to disable encryption in order to have full-fledged backup-recovery option in TWRP next time you use it. To do so you will have to format data partition. After that step you will loose all you applications and user data for them, so you should backup it previously. After you format the data, flash Magisk first, then flash encryption disabling script from this post. Now you can boot to OS.
Note, that attached TWRP is only valid for firmware CUBOT_KINGKONG_MINI_9101C_V06_20191121. Cubot has released a new one and you can try to use the TWRP with it, but there is no guarantee it will work correctly.

well well, finally and serranoltexx successor?
i ordered one yesterday and am looking forward to get an suiteable replacement for my S4 MiNi [serranoltexx]

I saw 2 places talking about TWRP in King Kong Mini but I don't know if is safe:

Based on the second poster here and someone else who sent me a pm, I believe the TWRP is safe, I haven't tested it myself yet but I plan to at some point and will post here when I do. When I'm using it as my primary device and everything is working okay it's hard to justify messing with it more at the moment!

I did it to replacement my old Samsung J1 ace, very similar of S4 Mini, and I'm not regretful for that.

I understood but the point is if the TWRP source is confiable. I asked the official TWRP Team about the unofficials TWRP on websites in my last post, and they answer: "Hello, we do not run that site, so I cannot confirm the validity of their images."
So, I wonder how safe the unofficial TWRP images are.

This is a very important information. When I did a update firmware the usb cable disconnected and the mobile died. Black screen. The side buttons died too. Only blue led turn on when the usb cable is connected on PC. The windows 10 only recognized the mobile as "unknown usb device (device descriptor request failed)". I thought that had lose the mobile. A few days later when I connect the mobile in the PC, the battery image was showed on screen with 18% of charge and I saw in that moment that I could flash the firmware again.
I flashed official firmware and the mobile worked again but now it died again... because I did a wrong recovery boot. I will wait discharge the battery again. :crying:

Yes, indeed there were three times I thought I had totally bricked and each time I was so annoyed with myself! The key is to not charge it much until you are happy with the ROM you put on.
The amount of drivers I tried to use for different OS' when I got that "unknown USB device" on Windows and Linux didn't detect it was all a waste of time!

Well... the battery image appeared again and I uploaded firmware again. I installed the Magisk in the boot recovery, because this only way to install the Magisk on devices that are using system-as-root, but the Magisk disable my 2 SIM cards. When I boot without Magisk, all back to normal.
I serched for any solution for that but I didn't find.
So, my conclusion is that the Magisk not works to Cubot King Kong Mini. How can I stay with a phone with no SIM card?
I give up.

For me I can only get root when I patched Magisk to Recovery and then boot to Recovery and it doesn't see my SIM card but I have root, so I reboot every time I need root which is a bit annoying...

It is very complicated everytime when need "root", to have power off and on the mobile in recovery boot mode. Besides that, run out of SIM card working is not an option.
I will try to get support of this issue with Magisk Team.
Thank you for share your experience.

Hello,
Does anybody can confirm, that this is working with the new firmware?

I tried the TWRP a few days ago and was able to boot to it but I couldn't mount it to see my files, it asked for a password and I tried "default_password" and creating a password for the phone but that also didn't work. A possibility is to change the file format to ext2 and then to ext4 but I didn't want to try it when I couldn't back it up.

You will not be able to mount and/or use the backup feature of the TWRP until you disable an encryption by formating the data partition and running the script (just press "Cancel" in the TWRP to be able to do that when it asks for the password). Read my original post very carefully. There is a complete sequence of steps in it. Have you tried the TWRP with the last firmware? How did the rest of the system work?

I'm using treble AOSP Android 9 so not the latest firmware. I thought disabling the verification when installing that would be enough but maybe I do need to do those other steps. I can see the /system directory through TWRP so that's probably because that's the one I flashed, but I can't see the internal storage otherwise.

You need to put the "Disable_Dm-Verity_ForceEncrypt_02.04.2019.zip" file into SD card or internal memory to install by TWRP. This file disable the asking of password. Worked for me.

Thanks, I'll check it out!

Anyone else having problems with sensors on this phone? Rotating and compass do not work for me. That's what you get for buying a cheap Chinese phone, I guess.
EDIT: Downgrading firmware back to CUBOT_KINGKONG_MINI_9101C_V06_20191121 seems to fix some problems, rotation works, but compass is still buggy.

Never tried compass but haven't had any problems with rotation.

Tried to install root on a friends kkm but I can't get it working in the os. Is there any chance to get it working there? I am only able to get root access in twrp. Maybe an gsi with root is that possible?
