HELP PLS! downgrade p8lite fail. - P8lite Q&A, Help & Troubleshooting

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.

Upgrading to EMUI 4.0 via HiSuite ROM Installing option

Hello XDA!
My current build number is C636B170 and i want to install C432B550 Marshmallow update. I tried the "Local Update" option but it fails everytime.
The ROM Flashing option in HiSuite, can i install the update with that option? I would be happy if someone gave me an answer for my problem.
Thanks
You can't, either you wait for an official update for your Custc or you change your Custc (c636) to (c432) by
First: unlocking your bootloader
Second: download (c432b052) firmware and flash it.
Then download the b170 and local update it then you can download and update to b550
All the tutorial can be found in xda by little search

Ok. Thanks. I will try that out.
Unlocking bootloader means only my warranty is void, yes?
And after is there anything else i should know before doing so?

You have been a good help for me till now. Can you please help me with this too?
I flashed a ROM which is based to C432B052 but it kinda made my sim unusable for that ROM. And i was unable to local update either.
I want to know
1. A site where i can download official firmware for my phone
2. How to properly install it with fastboot (i can do it but i feel like i am missing something very important)
Thanks

you may lose your imei after flashing b052 but you will be able to restore it after updating to b170
btw your phone is dual sim or single sim ? from the build number you gave before it should be a dual sim, if it is then continue.
after flashing b052 download b170 and extract it then take the update.app and make a folder in the root of your device named (dload) and put it there. you should find the update in the local update.

C432 OTA changed build number to NRD90M test-keys

Hello,
I was on build C432B192 and got C432B560 OTA in the updater. All went good and I have EMUI 5.0 Android 7. But my build number now shows NRD90M test-keys.
Will it cause any problems? How is it possible that official OTA update changed my build number to test-keys?
Before OTA, don't you had a problem with phone themes? You were root?

Hello. I have the same problem. And many others, no gboard. I am root witn TWRP. When i reboot the bootloader is red with error. What is the solution. Thanks.
Download the rollback package on the forum.Then Flash B192 and upgrade to B560 . rollback will delete the dataļ¼ŒBack up the data first.

To fix the themes, just download SRK Tools. There's an option to push the themes back but of course you need to be rooted first.

You need bootloader code to unlock your bootloader. There's a HOW-TO get bootloader code in mate 8 thread. You can search for it. Good luck

Glad it work for you. Don't forget to hit the like button
how did you fix it ? because I cant solve the problem. cant run rollback, 3 button flash doesnt work, no more root , no more trwp installed , no adb access, this is crazy. you would suspect that with an OTA update you would not get stuck like this. now got no keyboard, no bluetooth, phone NXT-L29 unstable. anybody got a sollution for this huawei hickup?

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.

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...?
