Question: upgrading to Nougat while keeping root/twrp - Huawei P9 Lite Questions & Answers

My updater app keeps bothering me all the time that it has downloaded the new nougat upgrade (L31C432B371 and 1.25 GB in size in my case). Now I really want to do the update but my phone is rooted and TWRP is installed. My questions:
1) Should I install the update via TWRP or does the stock upater app (OTA) also work on a rooted phone?
2) Will I be able to keep root/TWRP and if not can I reinstall that in nougat?
Thank you guys and girls for any help.

Just don't update. The 1.25 is only the rom without the data. If you want to upgrade do it via Firmware finder . ( you will loose root and twrp if you update via ota or via firwmare finder. )

Thanks for the help. In firmware finder I can choose between FullOTA-MF (1.64 GB) and FullOTA-MF-PV (1.99 GB). I would go the latter one, right (1.99 GB)?
There is also a even newer version (B381) but looking here at xda that version seems to have some problems.

Thanks! So the the update mostly worked. All apps are there & bluetooth works.
However, my build is now NRD90M test-keys. Is that a problem and if it is, how could I fix it?
EDIT: nervermin, fixed it by flashing the upate_data_full_zip from this post: https://forum.xda-developers.com/hu...b360-links-t3565117/post71688774#post71688774

How can I restore brand firmware without twrp backup ?

Hi
I instaled the lastest firmware VNS-L31C432B161, but now need to revert back due to issues. Is this possible with the stock bootloader?
My Area code is now C900
thanks in advance
Download the rom you like and onstall it with the dload method
If you flash firmware VNS-L31C432B161 you can not return to any previous firmware that works ok...
You must have hope that Huawei launch another update that works ok again...

So it means once we flash B161 we can't downgrade (even with wipes ?) ?
Yes, it's corect. I realy want to hear from someone that can flash any firmware (less than B161)
after update to B161 (VNS-L21 or 31)...

That is not entirely true, you can install B160, which has the same problem ahah
But yeah, just hope for another firmware update from huawei..
Ok, starting from that 160 is less then 161, you have right...
But when i make update from B130 to B150 device updated ok, at version number is write right, B150 - this is ok.
But when i make update from B130 to B131 or from B150 to B151, version number is not changed at device properties...
Update procedure work ok, device restart, but version not changed...
I am curios in case of B160/B161 if firmware version is change...
What kind of bug do u have?

Install firmware finder and adjust setting to view last firmware
If it can't find nougat update , you can unlock bootloader and update via twrp method

I found the b563 fw but when i tried to update it it stopped at 1 % and the phone rebooted. What can cause the problem ?
Keep checking! Older firmwares have some small optimization to be done. So these guys r releasing slowly

On the firmware finder app, disable OTA, and you'll see that the ones that say FULL/OTA will disappear,
and the only FULL that shows up are the older (EMUI 4x) ones. At least that's what happens on
mine. L29C185B321
I just manage to update to b563 by first flash b211 using the dload method, and then i could update to b563 with firmware finder . Thanks for the help everybody !

Tried to do that 10 times still the same size
Hi,
Same issue for me. It's only 1.25GB update when I perform update request.
Already done the rollback to go back to MM with the B160 version. But when ask again for a new update request using HiCare, it's always the same update of 1.25GB and not the 1.99GB one.
My device is L31 too and no root or other thinks.
I have downloaded last last HiCare app but same issue, I really do not understand why an original stock device do not get the appropriat update...
Perform reset 3 or 4 times but always the same issue...
****ing "NRD90M test keys" version...
Other people are in the same case ? Any official help or tips for Huawei Service ?
Thanks
according to me i should try with back to mm> twrp and root> flash N
You need to be on B160 then go to HiCare app ( the one from playstore ) then update from there.

I had the same issue. This worked for me: Rollback to B160 via Rollback Image provided by Huawei. Then updated to B161 & then updated to B371, both steps via Firmware Finder and Firmware Finder Proxy. Now all seems to be working fine, no more 'NRD90M test keys' nonsense and missing stuff. Bluetooth is working fine which is my main requirement as this device is used for app testing, involving a lot of Bluetooth.

Hello!
First, let me tell you that you don't need to make X same threads or posts to get attention. One is enough. You just need to be patient.
You better wait for OTA.
The latest firmware is B350. I've used it on my CAN-L11 and I've found it better than B340, which was laggy a bit. The battery backup seems to be as EMUI 4.1, more or less (according to my usage).
The bug of Themes app can be fixed if you're rooted. Here's a guide about how to fix it.
In this post I've wrote the steps I've used to update to B350, through Firmware Finder. Just "click to show content". If you have locked bootloader, then skip the steps 3-->6.

It's said that firmwares from Firmware Finder are official ones, but I have no proof about that. I think B340 is a beta and prolly B350 too, not sure.
As I've said in my previous post, I've experienced some lags with B340 on my CAN-L11 and I can't recommend it. I didn't have any issues with B350 though.
There wasn't B350 neither when I've updated it. I installed B340 and then updated to B350 through Settings > System update.

As far as I know, you can't. You have to install C02 over C02 and C432 over C432. Someone correct me if I'm wrong.

[Firmware] Which firmware should i use to update to emui 5.xx with VNS-L31 C432 B226?

My phone had to be repaired last week, and the Huawei repair service changed everything in the phone except for the backplate.
However, I am now stuck with emui 4.1.2 in firmware VNS-L31 C432 B226, and i can't find a replacement firmware for the system.
The phone shows no update available in stock.
I have TWRP and magisk installed atm, just so i could try and get a different firmware with emui 5.1 or 5.0 at least, which I did to no avail.
Is there any way to find the correct firmware compatible with this phone?
Googling this firmware gives me no clues as to the correct path to updating this phone.
Should i use an adb/fastboot command prompt to update it, or use the dload method, or even the extract the SYSTEM.img from UPDATE.app method?
I just don't want to revert to an "earlier" version of the firmware with the dload method just to have my phone bricked.
These are the firmware i tried already:
[TO BE UPDATED]
TL/DR:
I have a Huawei P9 Lite repaired to a stock:
Firmware: VNS-L31 C432 B226
EMUI: 4.1.2
in Portugal.
I want to know a compatible firmware or series of firmware patches so i can get
Firmware: VNS-L31 C432 Bxxx
EMUI: 5.xx
Thank you for your time.
Hello,
it's strange that with an unbranded european firmware your phone didn't upgraded to android 7....
Anyhow i never done a forced upgrade but if i were you i wil try with HWOTA update, like explained in this thread.
So first make all your necessary backups, then unroot and finally follow the guide to upgrade.
P.S.: If your phone is dual sim try install B370, if single sim try with B371.
All the best

I tried a bunch of firmwares for emui 5.1 that didn't work, or which had NFC and bluetooth not working. I ended up downgrading to B160, and am now reupgrading to B370 after checking that both of the previously mentioned are working properly. I will update on this issue asap.
Also, it seems like the firmware I originally had was updated in march 2018, so it was really an updated official firmware with emui 4.1. What a weird setup. Could it be to make sure the NFC and bluetooth would be working? I just don't know...

I did it and it worked, however i flashed the recovery partition of version VNS-L31C432B380 with TWRP and now can't do a OTA update to B388.
Should I extract the recovery img from a b380 FULLOTA update and flash it to my recovery partition with fastboot?

Hey,
surely without stock recovery OTA updates won't work,
so yes try flash it with fastboot, then update to the latest/wanted firmware and finally unlock bootloader,
flash custom recovery and root (even if wanted).
Best regards
