Dear Esteemed XDA members,
I have spent literally days of testing and researching to try and unbrick my phone. Friends and family have seen my obsession with trying to fix this, some even offering to buy me a new phone!!!! But this ain't about money - this is about having control of my damn device!!! I'm usually pretty good with trying to solve this kind of stuff, but this time I'm truly stumped (and desperate, and obsessed!). I have come to the conclusion that it's directly related to ARM Trusted Firmware. Here are the details of my "journey" to date... please read it, and if you know how to fix it, please share!!! then I can get my life back!!!! Before I go any further, I am certain that my problem was initially triggered by doing an official update on a rooted phone. So to avoid experiencing the same problem I'm about to describe, it's best to unroot and relock your device before loading new official firmware.
I have a Huawei Honor 4x (Che2-UL00, with Kirin 620 chipset) with an unlocked bootloader. Recently, I tried to manually upgrade from Kitkat (emui3.0) to Lollipop (emui3.1), using the official update.app from huawei's website (image was good - I checked the hash). To load the update.app, I used the official huawei recovery. The progress bar went to roughly 90% and then hung. Upon restarting my phone, it went into rescue mode with the following error: Func NO : 15 (bl31 image) Error NO : 1 (security verify failed).
Interestingly, I looked closely at the fastboot.img files for kitkat Vs lollipop (I got the image files by using HuaweiUpdateExtractor). I noticed that only the lollipop fastboot image contains this error message text. Also, bl31 is related to ARM trusted firmware, for more info search for BL31 (Secure Monitor) on google, or see bl31_main.c in the Trusted Firmware source code. So it seems that the lollipop image is using the full ARM trusted firmware, an extra layer of security which is preventing the (unlocked) bootloader from allowing me to load into recovery. I think this is the core problem, and I think there is a way to solve it but I just don't have a deep enough understanding to get there. Below I'll explain each step I went though and provide some additional diagnostic info:
1. First step was to access recovery mode (Vol UP + power). This failed and resulted in same bl31 error message.
2. Second step was to try and update again using the three-button force update (Vol Up + Vol Down + Power). It vibrates once after a few seconds, and freezes with the logo screen with the red light flashing. As an experiment, I tried this without the SDCARD and noticed it vibrated almost instantly, which suggests that it does try to load something from the SDCARD when inserted. I didn't get any further in this mode.
3. Final step I tried was to load into fastboot (Vol Down + Power). This worked and I got into a special "Rescue&Fastboot" mode. First thing I tried was to manually downgrade to kitkat by flashing the kitkat images using the fastboot flash command. The images boot.img, system.img, recovery.img flashed successfully. cust.img simply failed. I desperately wanted to flash the kitkat fastboot.img which doesn't contain the trusted firmware bl31 image stuff, but fastboot replied: FAILED (remote: Command not allowed). In fact, many of the fastboot commands fail with this same error message, even though there is the "PHONE unlocked" writing in red on my phone screen. With the limited command set available (even fastboot oem device-info is not allowed!), here is the diagnostic info I was able to get:
a) fastboot oem check-rootinfo
(bootloader) old_stat: RISK
(bootloader) now_stat: SAFE
(bootloader) change_time: 1452356543
I think this change from RISK to SAFE is the core of my problem. the change_time is from several days ago when I attempted to update. I think it reflects the trusted firmware state (I'm guessing here, as I can't find documentation for these commands).
b) fastboot oem backdoor info
(bootloader) FB LockState: LOCKED
(bootloader) USER LockState: UNLOCKED
I think that FB LockState: LOCKED means that fastboot is locked (guessing again, can't find documentation!), which explains why many of the commands fail.
c) fastboot oem check-image
(bootloader) secure image verify successfully
I think this checks the recovery image, because when I flash a different recovery, this signature check fails
d) fastboot getvar rescue_phoneinfo
rescue_phoneinfo: Che2-UL00 V100R001CHNC00B365
This appears to be the ROM version at the time of purchase.
e) fastboot oem get-build-number
(bootloader): Che2-UL00 V100R001CHNC00B384
This actually corresponds to the build number of kitkat I was using just before the failed upgrade to lollipop.
f) fastboot oem relock mycode
FAILED (remote: root type not allowed).
I tried this just to see if it wold relock. I'm not sure what the error means, but I do not that this command failed with signature verify fail if i change the recovery image.
Here are the questions I want to ask:
1. Can I force the device to flash a new image? I can't get into recovery or have full access to fastboot commands due to the trusted firmware stuff. And as I mentioned earlier the three button trick fails with a freeze at the logo screen. It appears that I need to do this using a means other than fastboot. The only interface I have is Android Sooner ADB Interface. adb devices renders nothing. Only fastboot finds a device.
2. Can I somehow make the "security verify check" pass so that I don't get that bl31 error? I'm not sure exactly which images this bl31 thing is trying to verify! Perhaps some combination of images from the new lollipop stuff I tried to flash and the kitkat build I had running previously?
3. Can somehow disable all this Trusted Firmware stuff??
4. Any other suggestions???
This is driving me to the brink on insanity!!! Gotta figure it out!! Thanks for reading and trying to help!
Hi,
Did anyone solve this problem?
I'm facing the exact same situation.
Che2-UL00 too.
Thanks in advance!

I still find it hard to believe this problem absolutely cannot be solved. However, I took it to a Huawei service center and they weren't able to unbrick it either. They had to replace the mainboard, which seems like a complete waste. Cost around $50, so not the end of the world but still annoying.
Anyway, screw this whole "trusted firmware" rubbish. I'm the owner of the device, yet I'm not "trusted".
hello, i have exactly the same problem!
---------- Post added at 10:58 PM ---------- Previous post was at 10:41 PM ----------
Where do i get the replacement mainboard from?
Me too, upgrading kitkat to lollipop. Now facing that rescue error.
My Honor 4X is unlock bootloader and root before upgrading lollipop,
Im on the Oct 1 security update.
I ran the Nokia unlock apt I side loaded. There app gives me a error message of device not supported.
When I got into Developer Options turn on OEM unlocking Allow the boot loader to be unlocked I still get the message Device not supported, When I run there app
I know the boot loader is still locked because when I try to flash TWRP recovery I get this message
fastboot boot twrp.img
Sending 'boot.img' (38732 KB) OKAY [ 0.902s]
Booting FAILED (remote: 'unlock device to use this command')
fastboot: error: Command failed
So it very much seems like the boot loader is still locked.
Any suggestion thanks

Sigh,
1. There is absolutely no official bootloader unlock for this phone.
2. Though there is no official bootloader unlock, you can still Bloader unlock your phone using a paid service by TechMesto @Singhsk ...

I did see a tread about that thanks for the info.
my guess is its most likely not worth doing I dont see very many roms listed for the phone.
I guess its not very popular for that reason. Its a shame it seems like a nice phone. But the market is flooded with phones I dont see any thing that makes this one stand out
thanks for answer my question

Yeah, not much dev for this device. Probably because of no official bootloader unlocks and popularity of the device.
I followed the instructions here to unlock the A3 bootloader and these instructions to install TWRP and Magisk.
After toying around with things, losing Google Play certification and having push notifications in doze/app standby mode stop working, I decided to revert things back to stock and relock the bootloader.
Before modifying things, my phone was running the EU ROM with the November security patch: V10.3.12.0.PFQEUXM. I went here and downloaded the stock image archive for that version.
I use Linux, so I ran the flash_all_lock.sh script and everything seemed to work without any issues. There were no error messages and all the images seemed to be flashed successfully. At the end of the steps, the script locked the bootloader and the phone rebooted. It then showed the Android One logo for a second then immediately went into fastboot mode. I rebooted it again and this cycle repeated. If I tell fastboot to continue, I get this error:
Code:
$ fastboot continue
resuming boot...
FAILED (remote: Failed to load image from partition: Load Error)
finished. total time: 0.001s
I tried to reflash the images again, but I understandably get an error because the bootloader is locked now. Naturally, I tried to run the fastboot commands to unlock it again, but that also fails, presumably because I can't boot into the OS to toggle the developer option's "Allow OEM unlocking" switch:
Code:
$ fastboot flashing unlock
...
FAILED (remote: Flashing Unlock is not allowed
)
finished. total time: 0.000s
At this stage, I throw up my hands in failure and presume the device is now totally bricked. After taking a few days to relax about it, I figured I would ask on here if anyone has any thoughts that could help. I fully expect the handset to need replaced and will accept the responsibility for breaking it, although I don't know how I managed to break it.
Is there some way to unlock the bootloader now when I'm not able to actually boot into Android to toggle the option to allow unlocking it? Is the device just FUBAR at this stage? I feel like there would be some way to fix this, but I'm at a loss as to how without some help.

I am new to this, my phone also seemed unusable and with the application "miflash" through windows, I put the official rom and came back to life.
It also happened to me that I had to change the USB port on the PC so that it didn't fail me ...

Thanks for the reply. I actually tried this as well but it did not work. MiFlash just appears to be running the flash_all_lock.bat script on Windows and it failed because the bootloader was not already unlocked according to its debug logs when I ran it. I should have mentioned that above.
Not sure if it will help but did you try a factory reset?
Press and hold the Power+Volume Down buttons untill you see the android with the no command. Press and hold the Power button. Press and release the Volume Up button once then release the Power button. Then you should see some recovery options.
In can't get the phone to boot into recovery. Holding power and volume down just speedily reboots the phone into fastboot over and over. Using the volume up button instead just reboots the phone very fast. I never see the no command android.

Try
Code:
$ fastboot set_active a
. This is an issue with the flashing script. Before the line fastboot $* flashing lock command it should have fastboot $* set_active a. Your phone is not booting to system partition because the bootloader wasn't told which partition (a/b) to boot from.

The issue is caused by fastboot rom containing dummy system_b image and flashing script "forgetting" to force partition A as active. If a phone has B as an active partition and someone uses flash_all_lock.bat script, the phone's screwed. No idea what brought Xiaomi to this "brilliant" idea, not only there is a higher chance to brick the phone, but the zip file is also unnecessarily larger.
With locked bootloader it isn't possible to switch active partition anymore, so the phone is a (semi)brick. EDL mode is usually used to reflash locked bootloaders.
Idk, but I was flashing stock again after failed attemp to flash pixel experiance.Partition was set to B, after flash it wont boot, but I dont know why fastboot set_active b wouldnt work so I had to flash TWRP get into twrp set partitoin to A and flash stock rom again. Try that

There are two commands for setting active partition, depending on the fastboot version. It's either old
fastboot set_active a
or newer
fastboot --set-active=a

if you open flashing script file (.bat or .sh) in a text editor, you will see that fastboot is flashing system.img to system_a partition and system_other.img to system_b partition. That system_other.img is a dummy image and is not bootable. You either:
Option 1: Set active partition to A before running any stock flashing script.
Option 2: Replace system_other.img to system.img in the script.
Option 3: Force partition A after flashing userdata.img and before any lock or reboot command.

Stock rom was flashed in slot B instead of A and "flash all lock option" was checked off in mi flash (default setting). If I didnt know any better i'd think Xiaomi does this on purpose. I will never buy another Xiaomi.

You can't blame xiaomi for your negligence.
If you don't know what you are doing then either don't do it or ask people here on the forums or do some research yourself.
Of course xiaomi are going to have the flash all lock option enabled by default because the only time people would really use mi flash is to completely revert back to stock.
All information on miflash online will tell you make slot a active slot before flashing in mi flash.
Most manufacturers are the same nowadays anyway it's not just xiaomi.
All relevant information is there you just didn't read it/weren't careful when you flashed.
Don't ever be afraid to ask a question here on the forums if your not sure, you will get help even if you think the question is too noob or stupid.
You can always try get your system up and going through edl mode but you will need someone with a verified xiaomi account to help you.
Always read the relevant information before trying anything on your device.
To say you won't buy xiaomi again is silly seeing as it was a mistake on your behalf, "I cut my finger so that means all knives are crap" is kinda how it sounds

Theres always a fanboy in the crowd. Whoever programmed the batch file at Xiaomi made an error on wich slot it shouldve been flashed to. I've flashed devices a 100 times and never had an issue like this until i got a Xiaomi.
Now did I miss I needed to be on slot A? Yes I did. Still its Xiaomi's error for releasing botched firmware. How exactly do I find someone with EDL authorized account in US? If you have one, or if you can point me to someone who has one i'd be happy as a clam.
As a side note, my mother is from Cork.

Not a fanboy by any stretch of the imagination I just don't see it as an error on there behalf. They gave all relevant information on how to flash.
Someone already pointed out in a different thread of a guy that has the account here on XDA but I can't remember where I seen it. @_mysiak_ can you please let this guy know who has the verified mi account.
I hope you can get your device up and going and I do understand how frustrating this must be but it is fixable.
Hey maybe you can come visit Ireland with your mother and we can sort out the device then :laugh: joke

Ya I wouldn't go trusting some random Russian site either. I don't think there is anything you can do without either
A) going into edl and using a verified mi account
B) bringing it to a service centre (which nobody wants to do)
In fastboot you can't get any commands to work now right? Your device is fully locked again?

That Russian site is run by the XDA guy from what I understood. There are other paid services which have Xiaomi service accounts, I only pointed you to the cheapest "verified" eshop. Just Google another one if you don't trust Russians. All of them will need to connect to your PC over Teamviewer and do the flashing, you will just follow the instructions (connect the phone, reboot it etc.).
Greetings all,
I am having trouble attempting to root or even unlock the bootloader on my V60 (LM-V600TM), Android V11. Many guides online seem to gloss over needing the bootloader unlocked before root. TMALSS; I'm not sure if the non-international version can be bootloader unlocked and/or if I can root without needing this. Long version of what I've tried is below:
When following this guide on xda using KDZ,
I am getting stuck at Section 11.1.2:
Code:
C:\adb-platform-tools>fastboot flash frp frp.img
Sending 'frp' (512 KB) FAILED (remote: 'Download is not allowed on locked devices')
fastboot: error: Command failed
Thus to unlock the bootloader, I am following a guide from TWRPupdate:
It says to perform 'adb reboot bootloader' and then 'fastboot oem device-id':
Code:
C:\adb-platform-tools>fastboot device-id
fastboot: usage: unknown command device-id
My phone only reboots into normal mode whenever running reboot bootloader command within ADB.
I can run fastboot commands when I run 'adb reboot fastmode' but I don't believe this is true fastmode. As I have tried everything mentioned here, such as cables or different computers. Essentially most fastboot commands I've tried do not work except for showing my device as listed / connected.
I have also tried the drivers from LG / Google / ADB separately. And on 2 computers.
Is it possible that I don't have rescue mode or a bootloader still? As I get a black screen when entering recovery mode (but my computer recognizes A device), but adb nor fastboot does. I used to see the recovery screen logo, but I stopped seeing this screen either after updating to Android V11 or reading/backing-up the partitions in QFIL.
In last resort, I have tried rooting via patching the boot image using Magisk v23. I downloaded the firmware for my carrier, converted the KDZ to DZ via Python, and extracted the boot.img_117638 file. Given the file is 0 bytes with nothing in text edit, I still converted it to an img file. But in the kdztools android app, when I select this image file and run, I get:
Code:
!Invalid input file
!Installation failed
I'm guessing the boot.img file should have some data in it. But I'm not sure this method would even work due to the fastboot issues, especially with 'download to device' errors.
-------
I'm just at a standstill on what to even try next. I don't see many people having this much trouble unlocking/rooting their v60. Did the OTA Android v.11 break the root-ability?!
PS: Debugging and OEM unlock are both set in developer options. I can also list drivers used if need.
Thanks for the help in advance!
While digging I also found a post by alexenferman whom managed to use QFIL to root many older ZTE smartphones. They state it may but likely won't work on newer flagship phones. It's a great tutorial I'll have to try soon, but is there a reason it likely won't work here?

Why are you even in section 11.1? You have a v600TM ... a TMobile version. Not a Verizon version. Stop. Just stop. Jump to 11.2.
If you have gotten the engineering bootloader in place, you should be good to go with 11.2.

Haha, I remember reading that and still continued
I am on Verizon myself using this TM model. I know the phone was unlocked to the point where I could use it with Verizon. I even got 5g using my old 4g sim card.
Anyhow.. I have tried using that command already, and get the same 'command not supported issue'.
Code:
C:\adb-platform-tools>fastboot devices
LMV600TMc40cxxxx fastboot
C:\adb-platform-tools>fastboot oem unlock
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
Again have tried different computers and cables as I've read fastboot can be pretty picky too.
Did you select/enable OEM unlock within the Developer Options under Settings/System?

Yes I do, I have turned it off and back on as well.
Well then at this point, I'm tapped out. Smarter folks than me will need to step in and take up the mantle.

I ended up posting a form to reddit where about 10 people insisted I did something wrong, and with little surprise -- I did.
I did not flash the engineering bootloader after saving a copy.
Makes a lot more sense since it seemed like a lot of steps to backup without actually doing anything
Thanks NG for the help too!
are you success to unlock bootloader yet. if no i will show you
adb reboot fastboot> select reboot bootloader on your phone> fastboot oem unlock
ahsvanz
try
C:\ADB >fastboot devices
C:\ADB >fastboot OEM device-info
etc
replacing
C:\ADB with where ever you fastboot file is located
I too am having the same issue.
I recently wanted to try Android 12, I took a chinnese version of it and my phone is unusable, literally all chinnese.
I want to downgrade, I enabled Debugging and Oeam Unlock in Dev options but I get the ''remote: 'Flashing Unlock is not allowed"" when I try to fastboot oem unlock, I tried different USB ports, I keep updating all my drivers for ADB but nothing is working. I'm panicking a bit cause I don't have a phone to use, and not many people work with ONEPLUS in my country.
If someone has an answer, please save me lol

have you tried the code above ??
cant you just download the official original firmware and flash that ? im not familiar with the oneplus flashing techniques, ive always had samsungs except for the htc evo 3d back in the day
I tried them all, nothing seems to work
I'm stuck at 'Flashing unlock is not allowed'. I've set up everything I need to in Developer Options, I made sure they're all enabled.
It's really weird, could it potentially be a software issue? The software itself will not allow me to unlock OEM even though the check is turned on?

how does the one plus flash firmware ? for samsung we use a tool called odin, do you not have a similar tool for your device ?
I don't recall having any toolkit like that, but in order for the toolkit to work.. do you need to have an unlocked bootloader?
Cause the main issue is that I can't unlock it.
i dont think so, if your flashing an official firmware, but for your device i cant be sure of that
?
did you try running your commands as an su , is your device rooted ? you could try sideloading an update.zip maybe
what does it say when you flash this command ? true, true false ?
C:\ADB>fastboot OEM device-info
maybe this will help https://forum.xda-developers.com/t/...us-2-back-to-stock-100.3269543/#post-64279667

OK try
c:\adb
Adb fastboot oem device-info
Replacing
C:\adb
With where ever your fastboot is located
Just to check if your device is showing is oem locked or unlocked, it will display with a true or false option. I can't really advise to much as I don't have experience with that device
You could also try
fastboot oem unlock_critical
Not sure if that will work for your device though
Idk what else to recommend, are you stuck at boot ? Can u boot into recovery mode ? Do u have an ext sd card slot

Have youlooked at that
if you can confirm your phone has a mtk chipset use mtkclient to bootloader unlock it https://github.com/bkerler/mtkclient
otherwise youre out of luck

im not stuck at boot, i want to flash gsi but it says device is in locked state even with oem unlocked in dev options, adb debugging enabled etc , and just wont let me flash.. its starts flashing and then fails due to locked state

If the flashing starts, and fails, the os would be overwritten and you wouldn't be able to boot. So what you mean is the process trys to start but fails, right yh then I don't know what else I can say to try and help, let's hope mtkclient is an avenue you can pursue
