[Q] Installed the wrong root System File

Hi there, first topic on XdaDev, as I really need some help here.
I flashed the wrong system file on my Zenfone 2, I installed the 550ML version instead of the 551 one, at first I had a black screen but managed to get a clean install and the phone seem to work fine. But it is also running at the settings of the 550ML, which means 720p resolution and lower CPU frequency, and I would like to roll back to the original settings of the 551ML with the stock firmware if possible.
My issue is that I cannot load the System.img anymore. I follow these steps :
In CMD:
"Adb reboot-bootloader"
Daemon started successfully - The phone reboots in fastboot mode
Then I enter:
"fastboot flash system system.img"
but I encounter the "cannot load system.img" issue
What am I supposed to do now ?
Thanks for any advice you can provide guys.
PS : The system file is inside my fastboot folder and this file is a rooted one, I also downloaded the firmware from Asus but I have no idea how to use it.
EDIT : So I finally managed to go back to the correct rooted system, which is the 551ML, thanks to this topic : http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596
But I have another question, as it is my first android phone : If I want to update my system, will I encounter issues with the rooting ? What if I want to roll back to the stock system, how do I proceed ? Thank you guys, amazing forum you have there.

you can't go back right now,a file need another compatible file so you just have to reflash all the stuff from the beginning.
enter bootloader.wipe cache.in bootloader.ABSOLUTELY DONT SHUT DOWN.it can takes 15-20 minutes too.download latest firmware (2.19.40) for 551ml from here mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw check if your device is ww or cn.unzip the file and move the files in the adb/fastboot folder.these are the sizes of the files you should have in the adb/fastboot folder
droidboot.img should be ~ 13MB
recovery.img should be ~ 11MB
boot.img should be ~ 11MB
system.img shuld be ~ 2GB
connect to pc.enter bootloader again.type ' fastboot devices ' to see if your device is recognized
flash files in this order.at the end of each line type enter
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
then choose normal boot in bootloader.after all,wipe cache again
you will have a rooted firmware.good luck man

[551ml] flashboot FAILD (remote: flash_cmds error!) Im stuck in fastboot

HW_Version -
Bootloader Version - unknown
IFWI Version - 0094 - 1069
Serial Number - my #
Signing - ?
Secure_boot - ?
RESULT: FAILD (remote: flash_cmds error!)
Thats what my bootloader looks like. What happened was I tried to update from Stock .184 to the new MM build. I downloaded the file and got prompted the update in my phone. It installed or did something and when it rebooted I was stuck in a bootloop with no screen.
I ended up using xFSTK Downloader everything went fine, my phone turned on with 4 colored bars and brought me in to the bootloader. I proceed to use Asus Flash Tool to flash the raw file of .194 and that's where my problem started.
It was taking soo long so I took my dog out for a good 15-20 min walk came back and the flash tool was still doing its thing and the green bar was still moving and on my phone it said RESULT OKAY.
I ended up closing the Flash Tool because it was taking soo long. I rebooted my phone then it goes in a bootloop with the 4 colored bars on the screen. Then I just keep repeating these steps and can't get anywhere.
When I am able to get in the bootloader after using xFSTK Downloader I cant use some flashboot commands. I cant flash twrp because I get FAILD (remote: flash_cmds error!) .
I was going by this guide here. http://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
EDIT: I just noticed that my phone doesnt come up as MOOREFIELD in device manager. when it turns on and goes in to the bootloader it shows for a second and goes away.
I'm very thankful for anyone that responds. Thx for reading.

I just had this problem after a bad flash~
The instructions of unbricking the phone was lacking some infos.
So I tried a lot of experiments just to unbrick this piece of crap XD
If you are successful on xFSTK procedure you'll end up on "fastboot" mode.
Then you'll proceed with the flashing tool. According to your description everything is just normal my mate~
Now this is the REAL DEAL.
You may notice an ENDLESS "Flash Image" on your flash tool.
Now look on your phone in the Fastboot mode. If you see that the "RESULT: OKAY" seems got stuck, its ok my friend its normal (it will take about 10-30mins depending on your PC).
• Unplug your phone, re-plug it in
• Close AFT
• End process "a500cgfastboot.exe" in the task manager"
Then do the FASTBOOT commands:
• fastboot flash splashimage splashimage.img
• fastboot fastboot flash droidboot.img
• fastboot flash boot boot.img
• fastboot flash recovery recovery.img
AND! you can now proceed on your recovery menu.
You may ADB Sideload the stock firmware by doing
• adb sideload UL-Z00A-WW-X.XX.XX.XX-user.zip (replace the "X" of what file version you want to flash)
And wait for it to reboot. I really hope this helps you mate~
#cheers!

Reflash in xfstk, press dload ...power plus vol + together till phone recycles and flash begins , check my signature below for tutorial, read whole thread and watch video.
You may need to flash an earlier raw too from which the ifwi and fwr dnx and pos bin are made.

Just so you know why it happened. You HAVE to be at version 194 before you update to MM! Otherwise... Boom

This is not so, I sideloaded MM fine straight on .184
No problem sideloading

well lot of people facing problem. as you told that you are able to get into fastboot after xFSTK process. and you are unable to flash raw firmware file!!!! well perform xFSTK again. get into fastboot and perform following steps:
very first of all. rename .raw firmware file to .zip file and extract all files in there.. now place all files in adb and fastboot folder. open command window here. ( where you places files from raw firmware and adb and fast boot tool folder) perform the following commands
1. fastboot devices ( see if it is recognized: else plug out usb and plugin again)
2. fastboot oem erase_osip_header
3. fastboot oem erase_token
4. fastboot oem start_partitioning
5. fastboot flash /tmp/partition.tbl partition.tbl
6. fastboot oem partition /tmp/partition.tbl
7. fastboot erase system
8. fastboot erase cache
9. fastboot erase data
10. fastboot erase APD
11. fastboot erase ADF
12. fastboot oem wipe splashscreen
13. fastboot oem stop_partitioning
14. fastboot flash fastboot droidboot_sign.bin
15. fastboot flash token PROD_BOM_Full.bin
16. fastboot flash ifwi ifwi-prod.bin
17. fastboot flash splashscreen splash_sign.bin
18. fastboot flash boot boot_sign.bin
19. fastboot flash recovery recovery_sign.bin
20. fastboot flash APD APD.img

Thx for the detailed post.. I got in to my phone finally after messing with it all day yesterday and I close to throwing it against the wall lol. It worked like a charm.. I wonder why the flash tool wouldnt work.
Now how would I go about side loading .194 and installing a recovery like twrp again so I can back this thing up once i get to mm.

you can side load 194... works well... after 194 you can also install latest official marshmallow. but do not install custom recovery if you want to install lates MM. first install 194 then latest MM. then custom recovery

opps my bad. what you helped me with put .194 on my phone already. I ment am I able to download the MM rom and do the system update with it again. Or should I side load it? Im not sure how to side load. After I do get MM on what recovery do you recommend. I did have the latest TRWP before all this happend, Is that what caused this brick? because when it flashed mm before I think it brought me into trwp.

posting new thread. do not update to official MM if you have custom recovery or you have rooted phone. though after install MM you can install custom Recovery afterwards. not tried but i think will not cause any issue
yes cause of brick is custom recovery

I have no recovery installed I tried to get to bootloader with adb and it showed the android guy with a error. How do I go about flashing the new MM build. I really dont want to mess up my phone again lol. Only thing I have on its is .194 atm.
Is it ok to put the MM build on my internal storage and apply the system update from there?

Im sure what you mean sorry. I have .194 on my phone with the help of your steps in fastboot. It booted and im in my phone and its updating all my apps and stuff..
Do you mean factory restore in bootloader? If so I tried adb reboot recovery the phone restarts and goes to a screen with https://i.ytimg.com/vi/wuixmZ11Kyc/maxresdefault.jpg Im guessing if i cant get in to recovery I cant do a factory restore?
in fastboot my bootloader doesnt have a version number it just says unknown
EDIT when the picture above showed up I held the power button and vol + to get into recovery and its performing a factory reset atm.

Anyone else bricked ?
Unbrick and into system with correct serial and imei numbers in 20 mins ..see my signature for zubes ..
PS, save yourself days of pain , after xfstk , flash an earlier raw ..

Stuck on splash screen "Your device has been unlocked and can't be trusted."

Stuck on splash screen "Your device has been unlocked and can't be trusted."
Hello, first I apologize for my English.
After a factory reset of my Honor 7X ((BND-L21), and a failed flashing of TWRP, my device stuck on "Your device has been unlocked and can't be trusted...Your device is booting now..." at every boot.
I tried to re-flash TWRP recovery through fastboot (PHONE Unlocked, FRP Unlock). At every time the process on the command window works but when I want to boot into TWRP, nothing appears, the device reboot and got stuck on the same splash screen.
I can't boot into eRecovery (I think I deleted it...).
I can't use dload method (I tried but when I hold both volume buttons + power, nothing happens, it reboots into the same screen as usual.
I tried to unbrick the device with Huawei Multi-Tool, the process works but nothing new on the device.
I tried to drain the battery, without results.
If you want any precisions in order to help me, don't hesitate.
Thank you all very much, any help will be really appreciated.

There must be more to the story of what goes on to the device.
You only say factory reset and failed twrp install.
But also say the fastboot screen show successful flash of twrp.
So how did you flash it? What command?
Also say you cannot boot erecovery , think it erased. How, when?
I think maybe you flashed wrong partition, but need your input as to what command you used.

Thank you for your answer.
I flashed TWRP with the command "fastboot flash recovery_ramdisk twrp_7x.img".
Yes, at the beginning I would like to install a custom rom, but it failed so I did a factory reset with twrp. After that I tried to install the original firmware and unbrick the device with Huawei Multi-Tool (by following an other thread).
Everything goes well on Huawei MT screen, but not on the device (bootloop after rebooting).
I tried to force original firmware installation using Fastboot commands (fastboot erase name of partition and fastboot flash name of the partition file.img). I flashed system.img, cust.img, product.img, vendor.img, ramdisk.img.

Oooooh. Sounds like it's possible you have mixed Oreo and nougat partitions somehow
This I have seen before when using multi tool. When not correctly setup
Try from fastboot to get the prop file.
"Fastboot get prop"
I think is correct command.
I will check in my notes, when I can to see.
Interested in seeing what build number is shown if any .
And if possible to get a partition layout, but I don't think you can from fastboot alone.

Thank you but "fastboot get prop" is not the right command. If anybody has a solution it will be awesome.

Download the latest full ota package for your device (around 2gb)
Extract the contents of the update. App using huawei firmware extractor and
Flash
kernel
Ramdisk
Recover ramdisk
System and cust images using fastboot
After that flash the correct version of twrp for your device and then install images of version and vendor(found in update. App file) partitions using twrp.
.
This method worked for me

It didn't worked for me... Do you know any other method?

I tried many TWRP versions but the phone doesn't boot into TWRP...

Mixed Nougat/Oreo partitions

My Honor 7x (BND-L21) is totally bricked for the moment. I think there is Nougat and Oreo partitions at the same time because of Huawei Multi-Tool. Now I can't boot into recovery/eRecovery and the device stucks in the splash screen (bootloader unlocked). I think I have to rewrite all the partitions but I don't know how to do it... If anybody has a solution it will be greatly appreciated, I tried for 1 week!

If your device has a locked bootloader or frp follow these steps
First of charge your device for 1 hour in whatever mode it is..
https://www.androidfilehost.com/?fid=11050483647474828964
Then download the service rom from the above link
Extract the contents of the downloaded file. Copy the dload folder from the extracted files to a sdcard.. (Directly to it not on any directory)
Insert the sd card..
Press all the buttons until the emui logo comes.
After the flashing reaches 100 percent.. Reboot the device unlock the oem in developer option..
Step-2 (Computer)
Download adb drivers and fastboot and install them.
Download complete ota package for your device (make sure you have the correct build number because service rom has a different build number ) (download size will be above 2gb)
Extract all downloaded zip files. Then using huawei firmware extractor extract all contents of the update. app files.. (one update. App file in each zip files)
Copy
kernel. Img
Ramdisk. Img
System. Img
Cust. Img
Version. Img
Vendor. Img
And version. Img to the folder having adb files. And version and vendor files to sd card
//Make sure that the complete ota package you downloaded matches the os before the software brick(noughat or oreo) //
Open the adb folder and do shift plus right click to open command window there and connect your device in fastboot mode to pc
Use the below commands one by one each after completion
Fastboot devices(show your device if its connected)
Fastboot oem unlock (code obtained from huawei unlock page)
#factory rest occur
After tha enter fastboot mode again
Step-3
Fastboot flash ramdisk ramdisk.img
Fastboot flash recovery_ramdisk recovery_ramdisk. Img
Fastboot flash system system. Img
Fastboot flash cust cust.img
Flash twrp using
Fastboot flash recovery_ramdisk twrp. img
Boot your device to recovery mode.( Volume up plus power)
Flash version. Img to version partition and vendor. Img to vendor partition
If you want stock recovery back
Boot into fastboot mode
Enter the command
fastboot flash recovery_ramdisk recovery_ramdisk. Img
And do a reboot
Relock bootloader upto your wish..
Better keep oem unlocked in developer options
If you have both unlocked bootloader and frp follow from step 2
I heard huawei discontinued the unlock page
In that case use dc unlocker to find the code
It will cost some money

Thank you I will try this but the dload method didn't worked when I tried 4 days ago...

I can't go into dload update mode (when I hold all the physical buttons the phone restarts and this appears (picture 1) and got stuck on this screen).
Also I don't know why but the phone doesn't charge, when I unplug it after 1h of charge, it shows the critical battery screen (picture 2) and it goes off...
Any help is reaaly appreciated!

If battery is not charging, then it will not take a flash.
You can maybe try remove back cover and unplug battery, then reconnect see if it will take a charge.
As for your question about resetting with fastboot. You can wipe data, and maybe format system also. But I don't think that will help you.

My friend is asking help. His situation is similar. The phone is honor 6x.
My opinion is that something wrong with boot partition. you can ask some body extract the boot image from another phone. Then run "fastboot flash boot_ramdisk boot.img".
Hope it helps

Thank you for your answer.

I try to help again.
Describe problem please
As I recall it is as follows
** Phone working,
** Attempts some backup or restore using multi-tool
** This made phone no longer boot
**Possible that nougat images flashes to Oreo partition tanle (or visa- versa)
**Now no recovery or erecovery will even boot.
**Also phone shuts off with low battery as soon as cable unplugged.
If this is the case, I see no way forward. Because the battery needs to hold something in order for flashing to complete

Question Rooting - anyone successful?

I've been trying to root my Note 9T. The bootloader has been unlocked, and I've followed a guide from here: https://unofficialtwrp.com/twrp-3-4-2-root-redmi-note-9-5g-cannon/
I'm now stuck in a bootloop.
Anyone been successful?
I additionally tried using a different version of TWRP, which wiped the "misc" partition. Can anyone provide an image dump of the misc partition so I can flash it back on? I can't find a copy of misc in the stock firmware file.
UPDATE 1:
I put the full stock image back on and am back to having a working unrooted phone, so I don't need the misc image. Would really like to get this thing rooted though.
I've installed the Magisk APK, patched the boot image, and flashed it. But this also results in a boot loop. If I flash the stock image back it works again. Any ideas what's going on here?
UPDATE 2:
I got it working! The key was to flash the stock vbmeta.img with fastboot functions to disable it.
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Hiya. I've tried that and managed to get to the twrp page. However, when I go to install magisk via twrp, it just reboots into a bootloop. Any ideas?
Update: This seems to have worked.
[SOLVED] Phone gets stuck in bootloop if I try to install Magisk ZIP!
From the forum I followed these step to install magisk: - Patched my boot.img of my current rom using Magisk Manager and flashed via fastboot - After rebooting from fastboot it got stuck in recovery so had to wipe all data and it booted finally...
forum.xda-developers.com

Did you manage to get Magisk working after the reinstall of stock firmware, or you've just resolved the bootloop?

I've been trying to root my Note 9T. The bootloader has been unlocked, and I've followed a guide from here: https://unofficialtwrp.com/twrp-3-4-2-root-redmi-note-9-5g-cannon/
I'm now stuck in a bootloop.
Anyone been successful?
I additionally tried using a different version of TWRP, which wiped the "misc" partition. Can anyone provide an image dump of the misc partition so I can flash it back on? I can't find a copy of misc in the stock firmware file.
UPDATE 1:
I put the full stock image back on and am back to having a working unrooted phone, so I don't need the misc image. Would really like to get this thing rooted though.
I've installed the Magisk APK, patched the boot image, and flashed it. But this also results in a boot loop. If I flash the stock image back it works again. Any ideas what's going on here?

I'm interesting in at least rooting and if possible install TWRP .
Can you post i complete procedure to root the note 9 T ?
Thanks

I can have a go. But I'm not 100% sure what exact steps I took that got it working, as I flashed and re-flashed several times. Give this a try and let me know if it works or not?
WARNING: EXPECT TO LOSE ALL THE DATA ON YOUR PHONE!
Step 1
Obviously you need to unlock the bootloader first: https://en.miui.com/unlock/
If you haven't done this already, after your application it's likely you might have to wait 7 days before Xiaomi actually let you unlock.
Unlocking wipes your data.
Step 2
Start the phone normally. Copy the latest magisk apk (https://github.com/topjohnwu/Magisk/releases) over to the phone and install it.
Step 3
Find the correct original ROM for your device (https://xiaomifirmwareupdater.com/miui/cannong/). You'll need the full image. From the ROM extract the boot.img and vbmeta.img. Copy the boot.img over to your phone.
Step 4
In magisk choose the option to install and select "Select and Patch a File" (should be the only option anyway). Select the boot.img you copied over. This will produce a new file called something like "magisk_patched-22100_XXXXX.img". Copy this file off your phone and onto your computer.
Step 5
Boot your phone to fastboot mode (you should already know how to do this, as you would have had to have done it to unlock your phone in the first place - Hold down Volume Down and the Power button at the same time).
Step 6
Run the following commands (obviously replace the boot image with the correct magisk image, and use the vbmeta.img you took from the ROM):
Code:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot flash boot magisk_patched-22100_XXXXX.img
Hopefully this will work. But I can't be 100% sure, as the disabling of "verity" could mean that your encrypted user data now can't be read (if you've only just unlocked the bootloader then you're not going to have any data anyway, so not too much of an issue). If this is the case it's likely you'll now need to factory reset the phone. Hold down Volume Up and Power on start to reach the stock recovery menu, and there's a selection for factory reset. You can also install TWRP at this point, and could then use it's factory reset function instead. I downloaded this version of TWRP: https://www.mediafire.com/file/ou8553psro9yyt2/3.4.2_redmi_note_9_5G.rar/file, which came from the other rooting guide (https://unofficialtwrp.com/twrp-3-4-2-root-redmi-note-9-5g-cannon/ - which didn't work). Just flash that version of TWRP to the recovery partition (fastboot flash recovery recovery.img), and ignore all the steps given in the guide it came from.
Let me know how you get on.

sorry for the answer delay.
Adding my 2 cents about unlocking the bootlader .
In order to do it .
FIRST - do not try it from a virtual PC . It does not work (at least it did not work for me)
SECOND , before to run the xiaomi batch_unlock bootlader , don't forget to update google usb drivers
I hard some hard time to just connect the unlocker to my phone . Now i have to wait 167 hours to complete the process .

should I be on the latest version of Miui...12.5 android 11? for me to be able to install twrp. i downgraded back to Miui 12.0.8.0 android 10 as i didnt like my data folder been blocked in android folder. My device is global cannong redmi 9T 5g with diminsity 800u soc, can you please help if you can. thanks in advance

Android 10 is fine. You need to fastboot flash recovery recovery.img
To boot into it you need to turn the phone off, then hold vol up and power until you feel a buzz, then let go.

I have the same Problem as HighEndGamer:
if I enter 'fastboot flash recovery recovery.img', it sayes that everything worked OK in just a few seconds. But nothing realy happend!
If I enter 'fastboot boot recovery.img', phone boot just as normal.
If I enter 'fastboot oem device-info', it sayes "FAILED (remote: unknown command)'.
If I enter 'fastboot oem lock', it works and I have to start from the beginning..
I have MIUI Global 12.0.2.0{QJEEUMX)

I confirm it does not work from a VM (and the need for latest drivers). There is something funky going on with the USB communication when running from a VM: the first call of the fastboot executable from the windows VM generally works fine, but any other call hang. So the batch_unlock tool cannot work (since it does call fastboot several times).
