i have huawei p8 model number GRACE GRA-C900B370 marshmallow and i have been trying to downgrade with no luck, the battery life is horrible on this android version.
i downloaded the OS and extracted the dload file and all and when it starts updating it doesn't go past 5%.
any help would be appreciated.
Apparently, 'great battery improvement' with the latest B380 (can update from B370): [Firmware][Leak]Huawei P8 B380 - GRA-L09C432B380
Have you tried it?
Hi, what have you decided to do in the end?
If you still want to downgrade, what have you tried so far? To which version & build number do you want to downgrade?
When you say "i downloaded the OS", which version & build number are you referring to & where did you download it from?
Hello,
I want to roll back from B161 to B160, so I can receive the beta Nougat update OTA. Is there any way to do this? I can't find any tutorial about rolling back B161 :-/
Hello,
I tried to install it via Huawei Firmware Finder (b360 from b150) but it ended up on nrdm-test key and missing lots of apps. Should I try to do it first with b331 and then b360 or?
Edit: b331 via Firmware Finder doesn't work as well, NDRM-Test keys and missing apps again.
Please someone write how to update to b360 or b331
Edit 2: Is there datafull for b331 or b360 so i can flash it via TWRP?

you better wait, im with your version too, wait for ota, for our reghion there is still no stable official update
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
