[Solved] FRP locked in bootloader after update to N an Rollback to MM - Mate 8 Q&A, Help & Troubleshooting

Hi guys..
I was with my L29 on KANG Vip Slim 368 and updated it to N ( http://www.carbontesla.com/2016/11/download-huawei-mate-8-b520-nougat-update-beta-middle-east/ ) with TWRP. The update finished, phone started, EMUI started, but when i checked the phone informations i saw that nothing changed.
So i decided to use the rollback file ( http://www.carbontesla.com/2016/11/download-mate-8-official-nougat-rollback-downgrade-package/ ) and go back to MM. I used the dload way. After the rollback finished, the phone restarted and from that point it stucked at the boot screen.
Ok, no problem i said to myself, I will reinstall TWRP and restore my backup. But it wasnt possible to use ADB to flash TWRP.
So i booted into the bootloader mode. And there i saw that my bootloader is still unlocked but FRP lock.
The problem is now:
Phone doesn't boot.
No more Stock recovery on the phone.
Not possible to flash TWRP or something else via ADB or SRK Tool because of RFP Lock
Not possible to lock bootloader because of RFP Lock
dload method doesn't work
I read all i can find here in XDA and on other sides, but i didn't found a solution to unlock FRP
Is there any solution or is my loved Mate8 dead forever?

I think just you need to flash user data file of your stock mm

How to flash? ADB commands don't work cause of FRP Lock in bootloader mode.

I tried the following command with fastboot:
fastboot oem frp-unlock
But i need a password, tried the bootloader unlock-code and my PIN. Both didn't work.
Any idea wich password is necessary for that command?

Can you enter stock recovery?

No, see OP.

My Mate is alive again !
After i tried to flash firmwares or TWRP in fastboot without success ( FRP Lock in Bootloader) in gave DC Phoenix a try.
I charged 15 credits ( 15 € ) and got 72 hours to flash FW.
After flashing the first FW (Nougat) Bootloader FRP was gone. In Phonesettings (Developer) i set OEM Unlocking and USB Debugging "ON"
The Nougat FW didnt work proper (no Keyboard and a lot of other bugs). But i wanted anyway to go back to my Kangvip Slim (TWRP Backup).
It tooks me many tries with different Rollback- and Stockfiles and TWRP Versions.
But finally i managed to flash TWRP with fastboot and restore my Backup.
Meanwhile i bought am Mate 9, but i will give it away and keep my loved Mate 8.

Well, so your bootloader is locked and OEM Unlocking is off.
No, i need some infos.
1. Which Mate 8 version do you have?
2. Did you unlock your bootloader before?
3. Which Nougat update did you use?
4. Which Rollback version did you try?
5. What happend after rollback?
6. Can you start erecovery?

Thanks for your help

Ok, what happens when you try:

?

It shows command : remote not allowed or something like that

The following is the way i would take, but i can't promise that it'll work. Maybe you try it and it won't work for you.
Google for DC-Phoenix
download the software, create account as "new user", buy 15 credits (number 21 in the list) for (Huawei MTK phone FRP Erase (Unlock factory reset protection) 15), remeber it's for 72 hours
Start DC Unlocker
Put your phone in fastboot mode (connected to your pc), flash the Nougat update.app
when it finished reboot your phone
enable developer mode, enable USB debbuging, enable OEM Unlocking (must be on)
If you made it to this point, you made big step to bring your Mate back to live.
We continue than...
And remember, no promise that it will work that way, maybe you lose your money.

I Would like try this option but the only Pc at home run on windows Xp and DC Phoenix don't want to work on it. Every time I try to login in my account this show an error message after a moment.
The others computers at home are all under OSX so I don't know if exist a solution using it.
May be do you have any other solution? Like force the unlock with fastboot commands?
Thank you very much for your help

Thats sound bad dude. That's the trick with DC-Phoenix, it has a way to use a backdoor. (It shows when you flash, first it tries the normal way, give fail, than it use the backdoor)
I searched for hours and the only thing that helped was DC-Phoenix.

hi, dc pheonix can unlock bootloader even frp is locked.
Only flash update.app still can't boot into system,
So I saved my p9lite with a trick.
It seems twrp damaged oeminfo and made dload flashing not work, while I flashing emui5. So while DC phoenix flashing update.app and phone unlocked, I used process explorer suspend DC pheonix process, then use flashboot flash oeminfo. Like:
Code:
fastboot flash oeminfo oeminfo.img
And after that dload flashing is okey.

Frp locked

Ok, here is the deal, i was being impatient, i flashed nougat yesterday on my phone, after flashing it there was no keyboard to enter my email to login, so i stupidly but unknowingly so changed my gmail password to an easier one cause the only input method i had was voice commands, anyways, i got helped out by another xda member, and i got FRP locked for changing my password, then i attempted to rollback to MM, now my bootloader is relocked and it says FRP LOCKED, the thing is i did a nandroid full backup with twrp of everything on my phone before starting all this and every step along the way when something went wrong i went to twrp to recover but the restore did not appear despite having it on my sd card so idk if it have to be on internal memory or there is something wrong with twrp, currently my phone is bricked and i need help recovering it since i am broke these days and i can't afford another phone and it's out of warranty, if the backup can be restored somehow or any other methods, please guys let me know, any help is greatly appreciated
i flashed rollback package, then b320, then black screen, then flashed b200 failed at 5%, b162 also failed at 5%, then flashed the rollback package one more time, now i am stuck with the huawei logo, can't flash anything else, any long press just shuts the phone for a second then takes me back to the huawei logo, i can only access the bootloader and it is FRP locked

Help with Bricked Honor 8

Hello everyone,
I bought a brand new FDR-L14 in the US and brought it to my country Argentina. After a few days the phone's WiFi died while i was downloading Nougat via regular EMUI updater. I finished downloading the remaining 5% using the data package and booted with the new android version with no issues aside from still not having WiFi. This is not a wifi signal issue since i just cannot turn it on. I read in a forum that maybe if i downgraded back to MM the Wifi issue could be solved. So this is what i did:
1. Downloaded the Rollback Package from the Honor site
2. Downloaded an full MM from Firmware Finder for the FDR-L14 version. The one listed in the support section of the Honor US site is for the L04 version.
3. Successfully ran the rollback package via DLOAD method (SD Card + 3 button method)
4. Successfully installed the MM version via DLOAD method (SD Card + 3 button method)
After this i booted normally but still no Wifi and this is where i messed up:
Instead of updating to Nougat using HICare (since i didn't have Wifi) i tried to force another update using DLOAD with Nougat. The update failed at 5% and i started to panic, so i also ran the rollback package successfully via DLOAD with no issues. After that, the phone just bricked : it stays at the blue screen with the logo forever.
So this is the current situation:
- No debugging enabled so i cannot unlock via fastboot.
- Both FRP and Bootloader Locked
- 3 button method doesn't work: Tried to activate it with the rollback package and 3 other update packages. It just doesn't work anymore.
- Fastboot works fine and I'm able to list the device while connected to a PC by running "fastboot devices" in CMD. The only problem is that since everything is locked i cannot flash any images or recovery.
- Recovery doesn't work either (Power and Volume Up)
- The cost of sending the phone back to the US is probably half the phone's price
- The warranty isn't valid here.
Is there something i can do to unbrick it? Ive been browsing the forums for 3 days and couldn't find anything aside from maybe trying to reflash an image using DC-Phoenix.
Any help is greatly appreciated!
vaya faena amigo, ya es mala suerte
what a mess
Any ideas? Im in a dead end here

You said your fastboot works, did you try to flash the update.app using adb?

ADB Commands are not allowed and cannot even Flash using flashboot because USB Debugging was disabled when it bricked.

You said you can boot your device to fastboot mode then why aren't you allowed to flash anything in fastboot using ADB? As Much as I know you don't in fastboot mode it doesn't matter if USB debugging is turned on or off.

With Bootloader and FRP Locked and no debug mode you cannot run any fastboot commands that will alter the system. It gives an error saying "Remote: Command not allowed".

I can't lock the bootloader. HELP!!!

Hi guys, I need help, because I can't relock my bootloader. I have Honor 8 L09C432
I was on Carbon ROM and I had TWRP installed, and I wanted to go back to stock ROM, so I followed a procedure that I found in a comment on some thread.
( This is a screenshot of a comment that I followed, if that means anything to you ) https://forum.xda-developers.com/attachment.php?attachmentid=4385584&stc=1&d=1515621906
I successfully returned to EMUI 5.0 and I'm currently on B360, and I wanted to update to B381. I got an OTA, I downloaded it, but installation failed, and that's, I guess, because the bootloader is unlocked.
I tried to lock the bootloader with some adb commands:
-adb devices ( my device would appear )
-adb reboot bootloader
-fastboot oem lock * Bootloader code *
and then I would get a message that says " FAILED (remote: Command not allowed) "
( Here's also a screenshot of that too ) https://dl.xda-developers.com/4/3/8/5/5/8/5/Capture2.PNG?key=L_OuO3DslYw7HJaIJW-mGw&ts=1515622403
I enabled USB Debugging and OEM unlock options in Developer options, but it still doesn't work...
If someone's knows why this is happening, or how can I update the phone without even locking, I would really appreciate that, thank you in advance, and If I didn't mention something that may be important, please tell me, so I can help you to help me
Use fastboot oem relock instead of lock.
Note that relocking isn't the same as locking, for that you'd have to flash something like MM via dload which automatically locks the bootloader. Some other official packages might work, too
Edit: Also you need to be in fastboot mode to actually use the fasboot commands. (power+vol. down)
I'm not sure if an unlocked bootloader should actually break the OTA but it's been a while.
You can just download the flashable (for TWRP) versions from FF ( the full ota mf-pv) and use those otherwise
Sent from my OnePlus5 using XDA Labs
I tried Fastboot oem relock too, but that also didn't work, and I was in fastboot mode when I typed in the commands. I don't have TWRP since I installed stock ROM ( EMUI ). I guess you are suggesting that I should downgrade to MM, so then the bootloader will be locked? Still, thank you for your time and help!
You don't need to lock the bootloader in order to take an update. However, you must have the stock boot and recovery .img loaded for it to work. Here is a link for instructions on how to do this. Keep in mind that my instructions only talk about extracting the boot.img, but in your case it is probably best to extract both the boot and recovery.img just like the video shows. Use the B360 firmware to extract the files from. This will ensure all of your partitions are stock and that will hopefully allow you to take the update OTA.

I messed up with Huawei Mate 9. Please Help.

Guys i have a really really big problem with mate 9 (MHA-L29). I broke both twrp and system same time (please don't ask why.)
Now, my phone don't open, just fastboot&rescue mode, useless huawei recovery (which can't format data neither install stock rom). Besides, i can't install stock rom because i tried once, and i downloaded wrong system file, and i can't format the phone now. Because of that, stock rom that i download sd card not working too. Because there is a dload file in phone.
worst of all, i can't install twrp again, because my fastboot screen tell me that: "Phone Unloced" (with red) "FRP Lock" (with green). When i try to install twrp, adb says "Failed, remote command not allowed"
Now, if can install the twrp, all my problems will be solve. There is 1 custom rom (RomAur) and 1 system backup.
How can i install twrp with this situation?
Please someone help me i spend 2 days and still nothing! How can i open this phone? Stock rom, with/without root, custom rom whatever, just tell me how can i open this phone
up
You get that command when trying to flash the wrong recovery partition, was your room nougat or Oreo based?? If nougat it's fastboot flash recovery recovery.img and Oreo fastboot flash recovery_ramdisk recovery.img I think you are trying to flash the wrong partition

With FRP lock you'll have to use DC-Phoenix.
But it costs €19 (For 3 days usage).
Simply put you can bypass FRP with it by force closing DC-Phoenix when it has activated the backdoor, after this you can flash anything from fastboot (until you reboot).
So you could use it to flash back TWRP.
Or you can use it to install stock firmware

Special Request
Hey ante . Is it possible to help me ? I rooted my phone 2 days back and messed it up while downloading a framework app which ended me up in a bootloop. I have been reading and following your posts of you helping others. I don't really get the steps what I should follow.
My phone is unlocked. FRP shows Unlock.
Rooted on oreo and I tried e-recovery and fastboot steps you mentioned in other threads using kernel and ramdisk etc. ( After this I have lost access to TWRP and I am simply getting EMUI Screen with options for Factory Data Reset and Wipe Cache Partition. I don't know where it is going to lead me next :-/.
Also downloaded Huawei Extractor and tried to extracted specific files but the firmware file I have doesn't have CUST.img file.
Also the site link you mentioned for download firmware is in some other language and I am unable to search for my firmware.
I also tried the placing update file in the dload on my sd card but fails at 5%. The file was correct and I am sure I did'n download the wrong firmware.
Currently it shows this on the fastboot screen.
Andorid reboot reason
: AP_S_ABNORMAL 32

Just don't know what I should be doing ? PLEASE HELP BRO?

What's your firmware now?
You can get that info in Fastboot using
Code:
fastboot oem get-product-model
fastboot oem get-build-number
Since your recovery and fastboot still functions you probably will only need to use HWOTA to get back to stock.
It can be found here: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-oreo-update-package-t3699522
But post your cust/build before proceeding.
Also cust.img is found in UPDATE.APP in the hw data zip.
Problem Solved - Somewhat
Hey ante. Thanks for the promt reply. I got it solved by using CHIMERA tool.
Would like to suggest others also stuck with same issue to use CHIMERA.
Note - It is a paid tool and 100% legit and it can help with all problems related to FRP, Bootloader Lock / Unlock & also flashes back to factory firmware.
However what I am facing now I have flashed another version of firmware which isn't my region and some features of my phone like fingerprint scanner and other things are not working but phone is back to live. So Im glad and looking forward to searching for clean Oreo Firmware for my region to flash using CHIMERA Again.
Also, the sick and stupid part of it. I went to the service center and a person non-technical told me straight that you lost your device and it's of no use now. We cannot fix such issues 99% but I'll still ask my team and let you know after 3 days.
Thank God I didn give them and wasted my time and money.
As soon as I returned, I followed up to things and got it done myself. :good:
Anybody can possibly suggest a official firmware Oreo EMUI for Middle East Region!? If not which one can be flashed instead and where to download from?

LOSQ/LiR - LineageOS 17.1/18.1-UNOFFICIAL-GSI

For those who want to try LineageOS 17.1/18.1-UNOFFICIAL-GSI . IMO stable enough to be used as your daily driver.
LOSQ/LiR is not developed nor maintained by me!
Credits: @eremitein
Requirements: basically full stock EMUI 9.1, with stock recovery_ramdisk.
Note: I prefer to install in fastboot mode, it's quick, easy and most importantly, safe.
IMPORTANT! Before booting up the ROM, you will need to perform a factory reset in stock recovery!
Install arm64-b.. only!
1. LOSQ - LineageOS 17.1-[10]-unofficial-GSI
with the GAPPS
GAPPS
without GAPPS
Vanilla
-----------------------
LiR- LineageOS 18.1-unofficial-[11]-GSI
Download
2. Extract the ROM .img file from the compressed file.
3. Flash extracted losq/lir... .img from fastboot , use command
fastboot flash system (file_name).img
4. Run command fastboot reboot, unplug your phone, when appears on screen yellow warning, press and hold for 3 sec Volume Up . In eRecovery select 'Wipe data/factory reset'.Reboot .

Magisk root (23.0):
(Note: If you don't plan to use TWRP, simply install patched Recovery_ramdisk in fastboot mode. Run command
fastboot flash recovery_ramdisk magisk_patched-23.img ),
- download and install Magisk manager-23.apk:
https://mega.nz/file/go0m2RiR#M5UTv6FPjWPtDaGPr-u2tpJMCwdf8uwnniZg69LiGfw
- Install TWRP-9.1
https://mega.nz/#!tkcTlATI!A8UJGPBGtxJbLcUOJoxCGJj5PFZXzCnjbb3OkwqKTP8
over eRecovery (it's necessary on EMUI 9.1):
- copy TWRP file to the SD card, and also copy to the SD card patched Recovery_ramdisk:
https://mega.nz/file/lp1kHLxJ#htCMaPjSsg_dy0w_jNOft-t_DZRAPwhOvwy_Wr2cjX8
- flash TWRP - run command
fastboot flash recovery_ramdisk (TWRP's_name).img
- boot into TWRP, select storage - SD Card, select "Install image", find TWRP-9.1.img file and mark eRecovery, swipe. Go back, find magisk_patched-23.img file, mark Recovery, swipe. Go back to the TWRP's main menu, select Reboot > Recovery. Done.
Note: you then need to boot your phone every time via Recovery. It'll boot into android as normal but with root.
( Note: for those who want keep the erecovery as a fail-safe:
https://forum.xda-developers.com/t/...-erecovery-with-twrp-installed-on-it.4357127/ )
To remove Magisk reinstall stock recovery_ramdisk via TWRP or fastboot , download Here
How to boot into TWRP:
- Turn off your phone, connect to the PC (or charger), then press and hold Power + Volume Up, device will reboot into eRecovery (= TWRP).
How to boot into patched Recovery :
- Restart your phone, when appears the yellow warning on the screen, press and hold Volume Up for ~ 2 sec,
release the button and immediately press and hold again for ~ 2 sec. Repeat it 6-7 times, the device will reboot into Stock Recovery (you can perform Wipe cache or Factory reset).

I have tried this rom - but without the magisk as I don't really care for root.. However.. This rom still has one big missing feature.. Fingerprint unlock. I can go to register fingerprint. Add the finger multible times to complete the circle.. however.. every time it misses just the last part - it will fail. If anyone has a fix for this I would be happy to use this as my daily driver as it works just fine.

I'm afraid you're wrong... It works perfectly for me.
Can confirm that so far everything works flawless. Fingerprint sensor is working on the phone too.
Thank you Alf.
Just two additional questions:
How will updates be perform in future?
How to switch from LOS 16 to this rom - the other P20 lite we have is still on v.16?
Cheers

Install Service ROM using dload method (9.1.0.132 recomm.) , then you can safely flash 17.1 GSI. Dload method will erase all your data and will lock the BL again!

Ugh, is there a way to install emui 9 without it locking my bootloader? I unlocked my bootloader via the @huaweihax method.

OTA update, via HiSuite, you can try also through eRecovery ...
make sure to have the stock recovery flash.

Idk how huaweihax method works, but the BL unlock
code is permanent, it wont expire, you use the same bootloader code to unlock if your device is relocked.
Btw, with EMUI 8 installed with May 2018 security patch you should be able to use DC-Unlocker or hcu-client to get BL unlock code for 4euros.
Or, you can also unlock BL for free using
PotatoNV method

There's no way I'm paying for unlocking!
The huaweihax method works this way: you give some information about your device and you flash a slock file to the ramdisk. It unlocks your phone.
To prevent EMUI 9 from re-locking your device, you can flash a zip file to have a custom bootloader unlock code.
Btw, I have hyperlinked the thread that describes this in the "thingy" word.
I guess that custom code should work even if my device is re-locked.

Sorry, this is not the DC-Phoenix support chat, let's please remember to keep conversations and comments in this thread about LOSQ - LineageOS 17.1, thanks...
Thanks @-Alf-
I followed all your advice in the LOS 16 thread to get 16 installed, but couldn't get gapps to work. So I thought lemme give LOS 17 a shot since it includes gapps, and it works great! However I get the same issue with fingerprint as @whitetigerdk. During fingerprint enrolment it works up until the last time you have to finger it, after which I get popup "Enrolment was not completed: Fingerprint enrolment didn't work. Try again or use a different finger". I can provide a screenshot but it's literally just that text.
Apart from that everything seems to work fine. Haven't installed magisk yet, will do that next.

Most of custom ROMs require lower build number, on latest build number may or may not work correctly.
If you have followed this guide to the letter and it didn't work, i'm afraid I cant help you .
I've not had any major issue with this LineageOS.
P.S.:
If all this has worked on my device, it does not mean that it goes with everyone else, and vice versa (we are talking about Huawei devices ).
@-Alf- Thanks, that might be it. I'm on firmware 9.1.0.200(C185E4R1P8T8) as that was the recommended one for LOS 16. Let me give it a shot with 132, will update with results.
Edit: With "Clean OS" I assume you mean a clean install of the stock ROM? My approach is to install 132 via dload, unlock bootloader, then follow your installation steps.

Yes, but I'm afraid there's no .132 build number for region C185 on androidhost.ru
IMO you can get it via paid service only, for 17euros , hm...look here
.132
The difference between .132 and .200 is google patch - may 2019 vs. july 2019.

What about this one? http://huawei-firmware.com/rom/huawei-p20-lite/ane-lx1/42056
It doesn't have a dload folder, it's just the update.zip basically, so I'm not sure how to flash it only unlocked my phone yesterday, not used to huawei roms yet.
Edit: they explain how here, you create the dload folder manually.

This guide is valid for Android 6 . Huawei-firmware is a really reliable website .

What do you mean really reliable when the guide is for Android 6? Is there a way to flash the 132 ROM from huawei-firmware?
Also, magisk installation worked perfectly by following your instructions. I can pass safety net with the universal safetynet fix module and got google play certification with the props module.
Is there a way to now boot into TWRP (erecovery)? Currently when booting it doesn't show the option to hold volume up to enter erecovery, it immediately says your phone is booting now. The only way to get into TWRP is to fastboot flash recovery twrp, do stuff there, then flash magisk_patched-ane-v21 over recovery and reboot.
Edit: I captured a logcat while getting the fingerprint enrollment error, there are some exceptions about the enrollment, not sure if that could mean something to the devs to help fix it?

Oops I thought I mentioned it in my post, mea culpa.
You have two options:
1. Turn off phone, connect to PC (or charger), then pres and hold Power + Volume Up, device will reboot into eRecovery (= TWRP).
2. Restart phone, when appears the yellow warning on screen, press Volume up, hold for ~ 2 sec,
release the button and immediately press and hold again for 2 sec, repeat it 6-7 times, the device will reboot into Stock Recovery , then you can do normal restart - Reboot system now.
