I have updated my Huawei P10 ( VTR-L29C185B172) to Oreo From Nougat using Firmware Finder. After Upgrading to Oreo, I thought Nougat was better. So, I decided to downgrade to Nougat.
So, using same formula I used firmware finder to install VTR-L29C185B172 update. It downloaded successfully. But, during installation process, It said that it
failed to check to update files, please download the package again.
Now every time I reboot or power off my phone It says that
Your device has failed verification and may not work properly.
I tried other updates of VTR-L29C185 but, nothing worked.
Then I follow some blog to downgrade my phone to nougat, but every time it stop at 6% and says that failed to check to update files, please download the package again.
I want to downgrade my phone to Nougat. Please Help me to downgrade my phone and take thanks in advance.
By the way my phone is not rooted.
I unlocked the bootloader using adb fastboot.
But last time i locked it using fastboot,

Hello.
I need a help with my Honor 8, it's been bricked and I honestly don't know if there is much to do in my current situation.
So the phone has locked bootloader and stock recovery.
Fastboot always returns 'Command not allowed'
What exactly happened:
I was running Stock ROM, rooted, TWRP Recovery with unlocked bootloader.
An official OTA update popped-up on my phone, I was in a rush and I missclicked (don't even ask lol) and the update started installing, I knew I'm screwed.
So I was about to play with fastboot, but it always returned 'Command not allowed'.
And probably the worst mistake happened a few minutes ago (6:00 am trying to fix it half a sleep), I was reading some posts about the dload method, >>FASTFORWARD I installed an official update using the dload method and locked my bootloader by doing this.
QUICK SUMMARY:
So I'm stuck on a bootloop.
The 3 button combo works.
Stock Recovery works as well.
Fastboot does NOT work. (I tried flashing, unlocking, temp-booting.. but nothing)
adb always returns error:
Code:
device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
Is there ANYTHING I can do in my current situation? :crying:
Thanks in advance for any help.
Have a nice day.
Hello, as long as you have an official recovery, a proper BOOT.IMG and the dload method is working there is still a chance( i hope), the only thing you need to know is that if the firmware is the wrong for your phone it will deny it. It means that is if you try to install an android 6.0 based stock ROM over a 7.0 ROM , it will say software upgrade failed or something like that.
You need to know under which Android version you were and install the same or maybe a more recent one but not to far away from your actual ROM, try the next one. You can also try to downgrade USING a rollback package that you can download on honor official site. Make sure that's the the correct file for your phone.
Hope you'll make it bro, let me know how the situation evolve

Hi Ryan,
Thank you so much for responding.
I could see two ROM in the official site http://www.hihonor.com/in/support/
HONOR 8 Firmware (FRD-L02, C675B130CUSTC675D002, India)
HONOR 8 Firmware (FRD-L02, Android 6.0, EMUI 4.1, C675B160, India Channel)
I tried with both the ROMs but no luck
I placed the update.APP file inside sdcard but the update stops at 5% showing that it has failed.
I also tried flashing the recovery.IMG in fastboot mode.
I have lost all the hopes in my new phone
In the rescue mode it says UNLOCKED.
Please guide me with some detailed steps.
Thanks
Flash the stock recovery of the ROM that was previously installed on your phone , then with dload method flash the rollback package downloaded from honor site , and finally flash one of the two ROM, it may resolve your issue because the phone won't accept a lower firmware without flashing the rollback package first. As long as you can use dload method it should be fine.
If it doesn't work try to flash boot.img , recovery.img, cust.img, vendor.img and system.img extracted from a clean firmware downloaded on honor official site
Let us know how the situation evolve
Hi guys, can someone help me out? I've relocked Phone and FRP unlocked. After factory reset, I still couldn't get OTA update on my phone. The security patch is 1st December 2016. I actually downgraded from custom rom to stock OS via Dload method. Now I couldn't get official OTA update.
I suggest to you to make a rollback for locked (not just relocked) device following my GUIDE and then make all the otas updates. If you can't recevie B399 you can follow my guide HERE.

So I tried your guide. With both FRP and Bootloader Unlocked from B386. First I flashed rollback package (Honor 8_Rollback Package_FRD-L09_from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1_C900B300_UK) then follow with firmware (Honor 8_Rollback Package_FRD-L09_from Android 7.0 EMUI 5.0 to Android 6.0 EMUI 4.1_C900B300_UK). Still didn't lock my back my phone to factory and still couldn't get OTA update. Anything I did wrong or missed out? I'm currently on B300.
Update 1: Next I'll try your second guide to force update on my device
Update 2: Successfully locked back my phone, currently on 1st December 2017 Security update, EMUI 5.0.1. However, I failed to install update2.zip update file though. Will that be a problem? I even wiped cache and low level factory reset my phone(from setting which I only managed to do so after I force reset from recovery beforehand).

Directly from @PalakMi
https://forum.xda-developers.com/honor-8/how-to/b399-flash-via-dload-mode-t3716885/post74814828
It took me 2 full days to finally successfully upgraded my ancient firmware (L09C16B170) to the updated version (L09C432B397). There are a lot pieces of information that I gathered from this forum and all over the internet that collectively helped me navigate this ordeal. Just want to share it with anyone who is in the same boat, although I know that P9 won't last for too long since P10 has been out for a while. However, if you still want to revive your P9, keep reading.
Requirement
Before reading, you need to understand ways of entering different modes of your P9 phone, which will be used many many times during your upgrade:
Enter recovery mode (also how you enter TWRP) - see this GUIDE
Enter fastboot mode - see this GUIDE
Enter manual upgrade mode (also called dload method; This is NOT TWRP method) - see this GUIDE. Please IGNORE any software or download information in this guide. I want you to refer to this guide for how to do it, NOT what to use or download!
You also need to download and know how to use ADB tool which is quite simple. Search the forum or google and you will find plenty of information and the download links. If you hate command lines, you can even use the GUI version from here.
You will probably also need to use Firmware Finder for Huawei (HWFF) to download firmware of interest for manual update during this process. HWFF is an app that can be installed for free via your phone Google Play Store. The downloaded firmware is saved under the HWFF folder in the internal memory. You might need to unzip these files for upgrade via dload method or directly via TWRP method without unzipping. However TWRP method requires you to unlock the bootloader and install TWRP in the phone (see below for details).
First step - debranding
If you are already on C432xxxx, you might just skip this step. I followed this thread partially (Debranding Guide by Z-Blade), since the whole thing doesn't work for me 100%.
Z-Blade did a fantastic job describing how to debrand his C34 firmware to C342B361. My original version is C16B170 which is a South Africa branded firmware. But I found certain steps in this guide could be omitted and certain steps didn't work in my case. Here is my modified version based on Z-Blade's version:
1. Unlock your bootloader and install TWRP
How to unlock bootloader? Follow this GUIDE. Even though it's for Huawei Ascend XT. It works for P9 as well. You only need to complete Part 1.
After you unlock the bootloader, install TWRP. Depending on which firmware version you're on, the version of TWRP that might work for your device changes. I encountered numerous booting loops due to incorrect version of TWRP. Finally I found that these three versions work for me (3.1.0-0, 3.1.1-0, 3.1.1-1). Always go with the highest version first (3.1.1-1). If you find yourself stuck in the booting screen, long press your power button until you get out of it and install another version of TWRP. Please go to TWRP official website to download TWRP for Huawei P9. Follow this GUIDE to install TWRP recovery on your phone.
2. Flash OEM info file for C432
After you unlock the bootloader and install TWRP recovery, download oeminfo-huawei-p9-eval09-c432.zip from this THREAD and flash it via TWRP method.
3. Flash C432B136 firmware
Download and flash the dload-huawei-p9-eval09-eva-b136.zip via dload method from this thread. After flashing and rebooting your phone, you should be on the L09C432B136 firmware. NOTE: If it boots up to a white screen asking you to enter password, reboot into recovery by holding volume up when you powering up your phone, do a wipe partition and factory reset. You may need to reboot your phone a number times before the phone boots up correctly.
Up to this stage, you have debranded your phone to an european version.
Second step - stepwise firmware upgrade
1. Update from B136 to B166 or B182
As mentioned in Z-Blade's original post, many people will not be able to directly update from B136 to B182. I am one of them. Go into the updater in the phone setting, refresh "check for update". If you can receive B182 update, by all means go for it. If you only receive B166 update, go for it as well. After B166 update and rebooting your phone, check updater again to see if you receive B182 update in the Settings menu. If this method does not work, manually update to B182 by following the steps here via dload method.
2. Update firmware from B182 to B360/361/378 and also upgrade OS from Android 6.0/EMUI 4.1.x to Android 7.0/EMUI 5.0
According to Z-Blade, "After your phone has rebooted and you are on the B182 firmware, you need to now update the firmware to B361 via Huawei Updater 2.0". However, in my case, I tried many times and always failed at this step. I found a workaround by updating to B360 instead of B361. Please follow this GUIDE to update to B360 or B361, whichever works for you. However, please pay attention to following change that I found critical:
- The version of Huawei HiSuite is critical for the success in this step. The GUIDE provided Hisuite download link (version 5.0.0.301_OVE). However, it does not work together with Huawei Updater 2.0 in my hands. This error has wasted me almost half day. Instead, I finally found out the problem and went to HERE to download the version 5.0.1.300 and it finally worked
- However, if even after HiSuite and Updater both work together fine the update does not proceed successfully (the updater might get stuck), you need to update it manually via dload method. Search EVA-L09C432B360 or EVA-L09C432B361 in Firmware Finder for Huawei as mentioned above and download the Full-OTA version (~2G). After download, move the corresponding folder containing firmware zip files under "HWFF" folder in the internal memory to the external SD card. Unzip the firmware file and update your phone using dload method. You may also try TWRP method which can install zip files directly, but at this point, you bootloader will be re-locked and TWRP will be gone. You need to unlock the bootloader and re-install TWRP again as mentioned above.
After you successfully update the firmware to B360 or B361, now you should have Android 7.0 and EMUI 5.0 on your phone. Now go to the updater in your phone setting. You should receive B378 OTA update. Proceed with the update...
You might not need to strictly follow following steps to update your phone to any firmware beyond B378. However, since a lot of new ROMs are based on B380+ or even B390+, if you want to use those, you might need to further update your firmware first.
2. Update firmware from B378 to B383
After updating to B378 and rebooting your phone, check if your phone receives B383 update OTA. If yes, proceed. If not, go to HWFF, download B383 Full-OTA firmware and update via either dload or TWRP method.
3. Update firmware from B383 to whatever later version
After successfully updating your phone to B383, you basically can flash your phone with anything firmware and ROMs built on B380+. I find it unnecessary to update to B386. What I did was that I directly updated from B383 to B394 by following this GUIDE. Since I wanted to try BlueWei 5.7 which is based off B397, I also followed the same guide to update my firmware to B397 before flashing BlueWei ROM.
Now please enjoy all kinds of new ROMs and the fast, revived P9. After this update, my P9 is super smooth (the original firmware and OS was utterly slow and sluggish) and I think I will keep using this phone until it really can't keep up with the hardware requirement of new apps etc.
Hope my guide is helpful!
Nice job to update things and summarize all together. Few comments, though
- Not necessary to go back to c432 b136, to b182 is enough:

https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
- For Nougat, please use Huawei P9 Nougat TWRP:
https://forum.xda-developers.com/p9/development/twrp-t3565703
- For DLOAD method, FullOTA-MF-PV versions should be used
- Besides the two methods listed to initiate DLOAD update, there is also a third one:

Hi guys,
I am currently trying to figure out how to reinstall a clean version of the B385 for my FRD-L04. I have downloaded these two files from the Nougat Update for FRD-L04 Honor 8 (USA):
Full ROM – http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1585/g104/v83098/f1/full/update.zip
Data File – http://update.hicloud.com:8180/TDS/...FRD-L04_hw_usa/update_full_FRD-L04_hw_usa.zip
I have tried to flash them both from TWRP, but I always get the error: Updater process ended error 7
Can anyone please guide me through the process and let me know what I'm doing wrong?
I have look for a guide or post where this is detailed, but without luck. Can anyone link me to a guide on how to reinstall the stock firmware in my Honor 8 FRD-L04?
Thanks! :good:
The best way (if you don't want to unlock bootloader) is to flash a downgrade package first, then dload the Marshmallow update and finally your preferred Nougat update though Firmware Finder.

Thanks for the response. In my case, my phone is rooted, so I don't mind unlocking the bootloader. Would you please elaborate on how to do it that way?

Unlock your bootloader and follow this guide:https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306/
Choose the B385 firmware or any newer firmware available for your region.
So I decided to finally reinstall the stock firmware in my Honor 8 FRD-L04 in B389, and this is where the nightmare began.
- I made a full backup with TWRP just in case and I decided I wanted to start from the earliest firmware possible available.
- I started unrooting my phone using the UnSU zip by Osmosis.
- Then I flash via bootloader the recovery and boot image of the firmware B360.
- I flashed the rollback package from the Huawei official site with the B122 firmware also available at the same place. I saved the rollback package in my root directory in the dload folder, and loaded it with the 3-button method. After this I wasn't able to boot my phone normally, I was stuck in a boot loop. I still continue with the next firmware, the B122, and it was successfully loaded (this also relocked my bootloader).
- It is important to say I clear many times the cache and wipe/erase data through stock recovery options, and also tried to erecover but I wans't able to connect to the WiFi. I guess something was missing (at this point I was already going crazy).
- I was still stucked at a boot loop after loading the B122, so I decided to unlock my bootloader and flash the twrp 3.1.1-1-frd.img
- From there I tried to wipe data and cache and system and everything, but I wasn't able because an error saying unable to mount always appeared.
- After rebooting, since I already had unlocked the bootloader, the initial message prompting: "press power to continue, press for 3 seconds for erecovery, etc..." appeared.
- I enter the erecovery options with the hope it will do something... and it did!!! I could connect this time through WiFi and the system asked to update the firmware and many other things it said at that moment. This was the first time I felt relieved through the night.
- The phone updated perfectly, it started at the firmware B122 and I kept updating it until I reached the B389.
- I unlocked the bootloader again and rooted the phone. And everything is running smooth as silk!
I know this is a very long story, but I just want to get it out there in case anyone is facing the same problem I just passed. Hope this helps someone and brings peace to them! =) Good luck!
I believe B385 is not functional with TWRP. Flash B360 and reboot to recovery. This should go to stock recovery, where you will have to do a factory reset. I got EMUI working, but it refuses to update to any newer version (it does show B380 but doesn't update). Also there should be updates after making that update. The updates did work for other people, so you may be able to have it working.

Greetings Everyone.
Am facing a problem with my 6X .. yesterday (and I don't know why) updated Magisk to the latest version and am not sure why I checked the DM-Verify option.
the phone rebooted and stuck with "your device is booting..".
I think it's something related to userdata and system encryption.
I can enter eRecovery and Fastboot,
am unable to flash anything due to FRP lock.
Am running debranded GR5 2017 to BLN 6x
OS is Oreo 8.0.0.510 (C675)
The bootloader is Unlocked.
am in thankful to everyone who will help.
Edit :
I can enter TWRP recovery (I think it still exists since debranding to BLN 6X).
Edit 15/02/2022:
I was able to fix my device by doing Board Factory Method Link, Then I did FRP by test points, after that flash using SDCard the EMUI 4.1 and EMUI 5 Firmware reaching official Nought firmware, last but not least, I did rebranding using this method Link and updated to Oreo 8.0.0.510.
now am facing a bit of lagging or slowness in the firmware while doing stuff. I think am going to update to firmware version 520 to see if the problem exists.
