Need help to downgrade from Nougat to Stock Rom

Hi all, i've been trying to fix this for 2 days and still failed to get it working.
I regret that i quickly jump into the nougat build and would like to get back to stock rom for now.
I tried downloading all the ROMs at stock rom thread and keep on encountering error when update reached 51% with software package/update failed error message.
I'm using P9-L19 and hopefully can revert back to C636 roms.
Thanks.:crying:

have you try this?

As someone new to this, this seems kinda complicated.
I'll give it a try. Just have to follow the instruction in the video?

Download the stock rom to external memory card in dload folder and use this code in phone dialer
*#*#2846579#*#*
And select update system

Flash update in dload don't work
Please help

Is your bootloader unlocked? Do you have a twrp backup?
I don't know if that's a good idea, but you could wipe system partition in twrp then flash stock recovery and try stock rom again? Going by the assumption that your current system is causing the update to fail.
Maybe nougat beta has a new recovery that won't flash old firmware? So maybe try an old recovery?
I'm just brainstorming though, no idea if any of this works. So try at your own risk.

Hello, my P9 is 100% origin.

I managed to use an OTG cable and put the firmware (update.app) on a flash drive under the dload folder. then powered the phone off and pressed both the volume keys + power and the flashing started

you need to download full stock rom the same version as you have before upgrade to N. then try to flash via project menu (*#*#2846579#*#*)
if this method doesn't work you may need to goto recovery menu and wipe data/factory reset. then you might lost all your theme and system apps.
but you will be back to to stable stock rom. if you need to use theme and need the stock system app again to have to Root your device. and install data/hw_init via SRKTool
Hope this help.

Do you have the full stock rom link available? I tried to wipe data/factory reset and it still remains at 7.0.

After wipe data you need to dload stock rom again though
What is your build number before goto 7.0?

First unlock your bootloader - then use Huawei Update extractor to extract ( I suggest the C636B168 Rom) from the Update.App the recovery.img - after flash from an adb folder the recovery.img through fastboot - use the three button to install the Rom and you're ready.
Warning.. everything in your internal storage will be erased so make a backup first.

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"
7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)
8. Unlock your bootloader again (important!) And make a factory reset
9. Your phone reboot (please wait ) and done!
Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..
P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone

In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...

You have a VNS-L31C432?
Your phone does not enter at dload mode?
Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.

What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.

I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)

Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.
I did format all partitions as told using a proper twrp this time.
What's next step, system says NO OS INSTALLED?

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...

Honor 5C can't flash nougat

Hi guys.
I'm having problem with flashing nougat on my NEM-L21C432B132. I'm on 6.0 at the moment and I used both dload folder on sdcard method and Firmware Finder. Tried different versions and I keep getting warning saying "incompatibility with current version". How do I solve this ?
I have no root, stock recovery, unlocked bootloader. I thought it could be because of unlocked BL, but I cannot seem to lock it as "fastboot oem lock" doesn't work for me.

Like I said it doesn't work for me as I keep getting "incompatibility with current version" error. I tried using the dialpad code and going to "Software Update" and tried the 3 buttons (VOL UP, DOWN and POWER ON ) method and I get the same error. Can I just install TWRP and flash the .zips I get from extracting the update.app file ?
EDIT: Just tried TWRP. I get error 7 and the flashing procedure doesn't even start

Hello,
I have extracted the update.app from the 6.0 version, flashed boot.img and recovery.img through fastboot, and my phone found the update even without using the Firmware Finder..strange but I have downloaded it and flashed without problems. My bootloader didn't even lock after flashing which happens from what I've read. Anyway I'm on the newest firmware ATM and also it's rooted. Maybe someone can explain that in case anyone had a similar problem in the future ?

Currently you have TWRP installed which is not stock recovery so dload method doesnt work.
Inorder to dload method work you need to have stock recovery.
Follow the procedure.
1. Take a nandroid back of the current system,boot, and other partitions, make sure the backup is not corrupt.
2.Now wipe all partitions through TWRP.
3.Now extract stock recovery.img from update.app of the version you like to downgrade using update extractor tool.
4.Now flash the the stock recovery.img using adb.
5.Now place the update.app in root dload folder of SD card and use there buttons to boot the system.
6.Wait the process to complete and you will have downgraded version.
Note the above method will work but proceed with caution.

(Help) My P8 Lite 2017 (PRA-LX1) is bricked

Hello,
I was trying to install a custom ROM from TWRP to my P8 Lite 2017 and I wiped all partitions except MicroSD.
The installation failed and I got the stock ROM and then I discovered that my bootloader is locked. I can access TWRP and when I flashed the stock ROM the phone just boots to TWRP Recovery. And I can't even unlock the bootloader because the phone doesn‘t have any OS and I can‘t enable OEM unlocking from the system settings. And because I have TWRP, I can’t access Huawei Recovery. So my phone is basically bricked.
Any help will be appreciated

You need to flash this 2 times,once for the firmware and second time for vendor,and the firmware UPDATE.APP can be found in the update_sd.zip and the vendor UPDATE.APP can be found in the PRA-L31 or PRA-L11 folders (most likely you will have PRA-L31,you can find this in the engineering menu by going into the dialer and typing this: *#*#2846579#*#*,and then going to Veneer Informations and Version Info,but since you cannot boot flash PRA-L31 vendor).
http://androidhost.ru/6uc - this is latest firmware,but takes a very very long time to download

If you don't know how to use dload you can look it up on forums.

Dload works no matter what,at least I was able to enter it when I bricked my phone,even when I completely screwed up my recovery partition,so you should be good. Try using it with the service firmware I left you.

Now I have downloaded the service firmware so how I am going to flash it now? Like do I extract the UPDATE.APP and flash it in TWRP or what? You said that flash UPDATE.APP, but am I going to do that in dload mode or TWRP?

In dload,make sure you make a folder in the root of your sdcard called dload and put that in there.

Hm,make sure you used the service firmware I left you,but if you are sure you did,your last resort is DC Phoenix which you will need to pay 20 euros.

Hello,
I was trying to install a custom ROM from TWRP to my P8 Lite 2017 and I wiped all partitions except MicroSD.
The installation failed and I got the stock ROM and then I discovered that my bootloader is locked. I can access TWRP and when I flashed the stock ROM the phone just boots to TWRP Recovery. And I can't even unlock the bootloader because the phone doesn‘t have any OS and I can‘t enable OEM unlocking from the system settings. And because I have TWRP, I can’t access Huawei Recovery. So my phone is basically bricked.
Any help will be appreciated

if you have TWRP installed could you make a backup of your oeminfo partition so we could provide you the right firmware to recover your device

Ok, but does it provide the right info if I have flashed different oeminfo.img?

I've tried a different firmware for my device and now I can't get to dload anymore so does it mean that I've chosen the wrong firmware? And by the way I read somewhere that if the dload says error it can depend on the microsd card.

I tried it again with the service firmware and I got to dload and it didn't have error anymore and now I've got everything worked and my phone is unbricked

great

I was stuck with a similar problem. Device bricked and flashing TWRP and restoring backups, then stock recovery and stock roms, but nothing worked until I found this post. Thanks a lot dinoderda for your help.

Hello again, I've been using the older service firmware for few months now and now I decided to install the latest service firmware after I had no success with flashing the firmware through TWRP and I downloaded the service firmware put the necessary files to the dload folder and installed it via the software update in the dialer and typing *#*#2846579#*#* and going to dload that way. It installed to 100% and then when it restarted it goes to Error Mode and it says to update the firmware again but it just loops to error mode and I cannot do anything so I think I accidentally removed some neccessary files in the dload folder but now I would need to fix the error mode loop.
