From (Med)Rom to stockrom need some advice/guidelines - Huawei P9 Lite Questions & Answers

Hi!
A while ago i managed to install medrom v3 on my phone. It worked well except for the play store. I read that this is caused by a version mismatch and i could be solved by flashing certain .img files.
Life happened and i didn't use the p9 lite for a while.
At the moment i got a phone with a unlocked bootloader and i want to go full stock with a locked bootloader.
I tried several things, like rollback files, 3 button method with a update.app and so on and i keep getting the : Software Install Failed error, indicating that the versions are mismatching.
It's a EU dual sim phone and the previous version before i medrommed it was stock: VNS-L31C432B130
And hints and guidelines on what to do ?
Thanks in advance!

Simo, thanks for your reply. I checked again and it was MEDRomV2 (your work ) not V3. Sorry the misinformation.
before reading your post i flashed 161 on it through 3-button. It said software install has failed, but MEDROM dissappeared, seems to be 'stock' atm. Playstore doesn't work and bootloader is still locked tho ?
Could you give me some guidelines on (which) oeminfo (and how) to flash ? And can i revert to unrooted/(re)locked bootloader/stock rom if i follow the instruction you gave me in the quoted post?
sorry for the late reply i don't have much time lately I appreciate your effort and time.

How's the camera on Medrom v2?

Hi friends,
I managed to solve my issue.
somehow i went from Medrom to Nougat 'test-keys'. From there i installed Revolution recovery, fixed the file system format to fat and back to ext4, then i installed the beta 336 Nougat, then i Rolled back to MM B160 and from there on i did the OTA to 370 and 380.
I am running a full stock (locked bootloader) L31C432B380 Rom now. Thanks for all the input.

Twrp for nougat

Hi everyone my device is huawei p9 lite L31 and I installed the unofficial update, after that I found out some apps are missing and the TWRP aswell so I can't flash nothing.
I would like someone to tell me which TWRP I can install and how please.
Thank you!
TWRP for Nougat doesn't support mounting of the /data partition at the moment, so there is nothing you can do about it. You should have flashed the update + data in the first place. All you can do now is unlock the bootloader, flash the oeminfo for your device and downgrade via the 3 buttons method. Next time, in TWRP for MM (which does support /data mounting), you will flash update + data for Nougat which I still can't understand nobody does.

Btw when I wanted to update I flashed both files and I think that the update wasn't complete with all files and system apps already.
Something went wrong, then. You should be able to find oeminfos in some thread here on XDA, otherwise google is your friend. Just be careful what you flash because you MUST flash the correct one for your device and locale

Use the same unlock code you've used before, get it again.
And why are you using that build B300, you could have at leasT tried B336, which in my opinion isn't having any problems noticeable, battery drain also good...people complain about this, but if you know what you're doing this will never be an issue.

Thanks for the response, I'll try tomorrow, i've already forgotten and deleted the code. Actually, it's all misunderstanding on why i flashed this build lol. I am planning to revert to MM stock and i'm still looking for some guide on how to. I tried other methods and didn't get luck. If you have any ideas would you mind helping me again? Thanks!

Yeah I've already seen this and i'm not sure on what to download, i tried once but it says
"software install failed!"
"Incompatibility with the current version.
Please download the correct update package."
and i can't still unlock my bootloader, the website is new, and it won't redirect me to unlocking SITE from this thread LINK.
also just wondering, in this method, is it require to unlock the bootloader ? thank you so much for helping me.

This method don't require unlocked bootloader, don't require TWRP.
Just get the rollback file and full MM update file.
Install rollback first then MM file after, put the extracted update.app files In the dload folder on root of sdcard, one by one after each install
Or
If you don't want to use rollback file, unlock bootloader, then flash patched oeminfo file via:
1.fastboot using this command: fastboot flash oeminfo xxx (xxx= name of oemifo zip you have, ie. fastboot flash oeminfo C432oeminfoDual.zip)
Or
2.while In fastboot flash revolution nougat recovery, then boot into it by "vol up + power" then flash the patched oeminfo,
Then once flashed OEMINFO then install via 3 buttons mode the update.app of your firmware, this must be in dload folder on sdcard as above.if asked for password then use "reset"

I was able to revert to MM using this HUAWEI P9 Lite Firmware i don't know how, but it worked today. LOL, lastly, i just have a question to revolutionaryTWRP, i tried it once when i was having problem with ROM, and it couldn't even mount internal storage, but for other people i saw here in xda, they can even flash zip files from it. just wondering if there are other Revolutionary TWRP versions or it's all about the tutorial on using RevolutionaryTWRP? anyways, thank you so much again. and how can i tag this thread as solved by the way?

Edit title to solved.
The current TWRP by Revolution for nougat can't mount /data partition, and if you need flash anything there, you've got to change filesystem as advised In the tutorials, but you can flash mods or apps to system partition without problems....this problem is In nougat TWRP only currently, MM TWRP has no issues at all...anyways good to hear your sorted!

HUAWEI P9 LITE NRD90M(test-keys) TO MM HELP Urgent

Plzzz help im stuck I want to rollback my huawei p9 lite VNS-L31 where its build number is NRD90M(test keys) to marshmallow 6.0 help don't know what to do . Plz if you can explain step by step what can i do because i'm not good in these things , My bluetooth not workng , there no calculator , no software updater , i am not able to check if got update or not and so on......, im stuck plz help
Well hey.. first download this rollback package from this link:
http://download-c1.huawei.com/download/downloadCenter?downloadId=93645&version=371484&siteCode=np
Extract and move all the files to dload folder on your external SD Card then install it with the 3 button method. If there's no dload folder then create one.
So the phone will reboot and now you can downgrade to any mm rom
Now just download this mm rom from this link:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66015/f1/full/update.zip
And again extract and move the files to dload folder on your sd card.. Install with 3 button method.
Done! Everything should work now!
In case If you don't know what the 3 button method is..lol
•Power the phone off ?
•Just press and hold on POWER + VOLUME UP + VOLUME DOWN buttons
The phone will start installing the rom and that's the 3 button method ?❤
this is not working for me. it says incompatibility with current version and to download the correct version.

Man, you have to do entire procedure: unlock bootloader, install twrp for Nougat and flash oeminfo for your phone. Before that you have to put in dload folder MM firmware (B130/B131),
because after flashing oeminfo phone try to repair firmware from dload folder. If repair do not start, power off phone and power on with 3 keys combination.
Hi All,
I'm having a similar issue as lennie27 however I think I might have strayed down an incorrect path during the process of upgrading to Nougat. My device shipped with VNS-L31C16B120 with no updates available through the stock updater. I tried the Firmware Finder guides which listed options for VNS-L31C169B13x and VNS-L31C432B13x however none of these updates would work, updater would say it's incompatible with current version. I also tried manually downloading the VNS-L31C432B160 firmware and installing that with the 3 button method as well as the EngineerMenu option with the same result (found guides that stated needing to be on B160 or B161 before making the jump to Nougat). Eventually I decided to unlock the bootloader and install Nougat through TWRP and followed the obeygeekupdate-huawei-p9-lite-to-android-7-0-nougat-manually guide (can't post links ) on manually installing Nougat (stupidly never paying attention to the fact that it's a beta build guide). I've installed TWRP to the device again using the P9 Lite Toolkit v0.0.0.11 found here on XDA (used this when on MM however the upgrade seemed to restore the stock recovery) with the idea of downloading the build from the ministryofsolutions huawei-p9-lite-vns-l31-nougat-b371-update-stable-europe page and pushing that to the device instead (however now the device doesn't want to boot into recovery)
Now my only concern is, will this work? I've noticed a bit of commenting going back and forth on the ministryofsolutions site which essentially boiled down to the need for debranding the phone (apparently C19 is MTN South Africa specific and I need to debrand it and get it onto C432 Europe before mucking about with Nougat, but alas to late) which seemed to be something I should have done while on MM still. If I can find a full firmware link for VNS-L31C16B120 can I flash that through TWRP without needing to follow any prerequisite steps? So far nothing that I've tried to flash using the three button method has worked, I'd just like to get back onto an official stable firmware again.
Any advice will be appreciated

you need to install nougat recovery, not the one from the toolkit. then twrp will work and the device will boot.
to go back to 120 you need to install oeminfo, and then the update.app

Thank you for the reply, managed to come right a few hours after posting. Turned out the copy of TWRP that I had on hand was more outdated than I thought, downloaded the newest copy and that worked on the device. Additionally I managed to find a website listing just about every firmware for the phone (Including my original MTN ZA specific variant) so I downloaded that and managed to restore the phone using the three button method. Phone is back to stock now and even the unlocked bootloader nag screen is gone so I'm guessing the bootloader is locked again as well One day when I'm brave enough to attempt this again I'll look at debranding the phone and getting it onto a C432 based ROM before getting it onto Nougat again.

Hello,
Search for the Huawei Recovery Updater thread,
download the .zip and your rom.
The guide is within the thread.
Pay attention and choose the correct rom, they are three files (FULL OTA - MF)
If you have any doubts about the rom let me know.
Neither the developers of HuRU nor I will take any responsibility
for what you do with your device.
Cheers

Thanks for the reply! but I have to download all three files (and what's the difference between the three)?
Then it's better if you install a previous version and then update or can I directly download the latest (of stock roms)?
I tried to download the B389 . I put the files in a folder in the SD (renaming them as they should) but after flashing i need to restore my phone. i try by twrp but it gives me an error "Failed to mount '/data (invalid argument)", Unable to mount storage

Well dude here i am.
Let's have to say and apologize for this....
before any attempt of flashing you should have done a full nandroid backup
and also know how to go back to stock. Maybe it's not your case.
So, i suggest you a method but you never wrote the firmware you had before
installing EliteRom.
The difference between the roms are ( obviously ) security patches and various fix, etc..,
as well as different versions for single and dual sim.
I wish ask you two questions:
What was the latest stock firmware your device was on and
are your DATA filesystem EXT4 ? (check into the TWRP )
HERE i wrote how i managed to install stock firmware and correctly relocked
the bootloader. ( depend what you want to do )

P8Lite stuck on huawei logo - had access to TWRP

Hello, it is my first post on this forum and it of course has to be problem. I am not expert in mobile phone hacking/flashing and this issue is too big for me to handle.
So like 6 hours ago i had working p8lite L21 with official android 6.0 and locked bootloader. I really wanted install costum rom due to performance issue, so i downgrade it back to 5.0 lolipop, than I root it with kingroot and successful extract key and unlock it using this tutorial: https://forum.xda-developers.com/newthread.php?do=newthread&f=4627
Than I flash recovery and install TWRP 3.0.2-0 and it all just worked. I was so happy that i manage to pull this off and I forgot that now i have EMUI 3.1 (ALE-L21C432B170) and i flashed phone with this:
https://forum.xda-developers.com/p8lite/development/rom-lineageos-14-1-p8-lite-t3824247
Of course it bricked because I missed that part with special version of TWRP. After that i tried to install something older just to get phone to work again:
https://forum.xda-developers.com/p8lite/development/rom-cyanogenmod-13-0-ale-l21-t3708835
And surprise, surprise, it did not work either and now I am stuck with huawei boot logo.
I did some research how to fix this issue, but i found so many different problems and solutions, I thought that at this point I really should ask for help because I just have no idea what i am doing now At this stage, can i just flash some costum rom (idc what exactly, just wanna to be lightweight) or i have to somehow restore original firmware? And if so how to do it? As i mentioned, i had access to TWRP.
Thanks a lot for your help in advance.
can someone help me with unbricking this phone? ?
@edit ok nevermind, i thought that this phone is cheap anyways so why not risk and just flashed boot/recovery/system from stock rom with fastboot. I did it and it works again, i needed just this simple hint to do it but i guess p8lite forum is dead.

Yea, i had access to twrp and fastboot. I already fixed it by flashing stock rom with fastboot. But maybe you can help me with other issue, currently i have android 5.0.1 emui 3.1 build c432b170 and i wanna install this rom:

I believe I can help you... Check the First Comment of that post... you'll see two additional firmwares... Only those firmwares have EMUI 4.1... b896 is for dual sim and b895 is for single sim... use any of those as per your requirements... after that download the LineageOS firmware and then proceed as per the Thread's recommended way... Also, before installing LineageOS, make sure you don't have any lockscreen lock...
feel free to ask if you have any more questions...

No worries, im happy that someone reply to me
So yea, i noticed those two softwares, i have two imei number so i picked b896 version for dual sim, but when i extract it and place in dload folder and try to update it via holding power button + -, i get software installation failed message. So I am not rly sure how to install this firmware, do i have to extract update.app and flash recovery/boot/system with fastboot, or i need to install it using some twrp? I look for guide but everyone are using this powerbutt + - methode to do this

Do you mean Vol +, Vol - and Power Button by powerbutton +- ? That's one way of flashing it, if you get error by that method, try it once again. If it doesn't work at all, then yes extract the update.app and go for the hard way...

Yea, i mean that i holding all three buttons (power vol+ vol-) and than it just says that installation failed. To flash it with fastboot i need to just flash recovery/boot/system or more files? I am asking because currently i have android 5 and this firmware is android 7 and I am just not sure if i can just simply flash those files and it will works.
Thanks for helping me

Which one are you trying to flash??? b896?? or simply LineageOS??
If it's b896, then I did read that it can only be flashed on ALE-L21C02xxx, but i am unsure about it... I did installed LineageOS and Resurrection Remix back in the days but I don't think I ever used C02 ROM for B896...
Also if you have the latest TWRP, you can simply flash with it... Try it...
