You can try flashing oeminfo and then stock UPDATE.app via force EMUI update, but data might get deleted

I can probably see right now, you've done it wrong... Download stock rom from huawei.consumer... For some reason i thought it's gonna be android MM, but it was android N, so no problem here, just download stock rom and you will have newest android.
You probably downloader rom from xda, rom it's in .zip right? And you tried to flash it with TWRP?

Yesterday I had this issue, it's more easy than it seems. In Revolution Recovery for Nougat, flash the update.app ZIP with 6.0 , it will show you a lot of errors, but don't worry, it's ok. After this flash than DUALSIMOEM.zip and after that shutdown your phone and use the 3 buttons method to automatically ,,update" to B161.

That's because u don t have the bootloader unlocked Also, verify in Developer Options to have Enable OEM on, that's why you have an error in CMD

hello
i unlocked bootloader and rooted my p8lite, twrp is installed. im on 6.0 marshmallow and want to downgrade to 170, when i bought it it was on 171,but i want dual sim. the problem is how to unroot it and install stock recovery,than install b300. i tried already but it said no update.app found. what could be the problem. i had supersu on my homescreen could not delete it after unroot. i searched all xda and google for it but cant figure out what to do next. i realy need this badly to do,because i cant open anything on my phone its like a tablet. if anyone can help me wth steps to try. i will try again to unroot,install stock recovery nad try again to force update b300 "UPDATE.APP".
can i install 170 on b300 or it must go, b300-b190-b170 and than b534 6.0?
pls help and thanks
Make sure the name is "update.app" and not "UPDATE.APP" for me b170 worked just fine after that last night.
Also b300 does not visibly change anything. And install the b170 from the dload by boothing the phone while holding all the three buttons on the right side and release when you see huawei logo.
you need to flash stock recovery. Then flash v052 via fastboot commands. (info and links you can find here on xda). Then you can do upgrade through EMUI updater (by local update files) - info about upgrade to dual sim you can find here, on xda, again). Those are my steps, tried few times. Good luck.
Probably you need unroot the phone.
i fixed it. thanks anyways.

I will try your method but firsr I have a question: If i restart my phone I get a message on my screen that my phone is unlocked and can't be trusted. So that means my bootloader is already unlocked and I don't have to unlock it again? So I only have to flash revolution recovery and find the file in firnware finder?
Is there a instruction how to install revolution recovery and where to find the file...?

Hi everyone, today I will be telling you all how to get back to stock as long as your bootloader states "PHONE Unlocked" and "FRP Unlock"
You will need to install this, this is super duper important! https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279
When installing, you will see the error: "E: Unknown command []]"
DO NOT BE AFRAID!
That is supposed to happen lol.
Installation procedure -
1. Flash this TWRP: https://drive.google.com/file/d/18uHjW73Th8iYKIs5m_QgwleMIOjsZd7S/view?usp=sharing
2. Wipe everything except SD card, then choose "Format data" to decrypt device
3. Reboot once again into TWRP (NOTE: If you are using USB OTG cable, make sure to plug it in AFTER TWRP is fully booted and ready to go, if you do it early, you get an error, which is weird lol. EDIT: Not sure if this error is still present in the new twrp, but it's never bad to play it safe.)
4. Flash HuRUpdater, make sure the file names are correct!
5. Reboot into stock recovery
6. Factory reset and wipe cache partition
7. Reboot
This method also enables themes to work again, so no need to worry about that!
Lots of thanks to @zxz0O0 to providing this awesome tool
And more thanks to the OpenKirin community for helping me out when flashing this! :good::good::good:
hello crayonicle, hehe im on the dot os for now, im interested going back to stock. will i get official updates backs from honor if i go back to stock using this method?

Yes, after flashing this via twrp, if you reboot once again to recovery, it is stock recovery, not twrp.

Hi guys!
I've installed a custom ROM on my device and now I want to switch back to the stock ROM, I don't have a nandroid backup, what can I do? I've tried some RUU's but when I boot in Download Mode, it doesn't read anything.

Just do a clean install (wipe internal memory also) and install the ruu
Also you can find multiple ruu files from the link thread below

So your phone have 8.0 firmware. If you want stock 8.0, just enter my post from link below and download stock zip flash by TWRP. If you want stock RUU, you need follow DOWNGRADE to Nougat post.

Your CID is rare for single sim variant
First you need a Ruu for ur specific CID
then the rest of the steps are pretty much the same.
