How to rollback from beta 7.0 with no bootloader. - Mate 8 General

Well I installed 7.0 but then tried to put twrp for 6.0 on my phone so now I've got no working bootloader looking to put 6.0 or full release 7.0 on my phone however now in settings it doesn't say my phone is l29xxxxxx it says something totally different.

I think you must unlock bootloader than with srk tool install stock recovery than dload to emui 4.1

Root with Ver. NRD90M test-keys

I have a Huawei VNS-L31 and got the update to Emui 5.0. I have now the Ver. NRD90M test-keys. Is it possible to root with the same method that I used before on Android Marshmallow? I also noted that some people say that they're stuck on this version. Is this one somehow bad?
Thanks!

I have nouget too you can easily downgrade if you do it right most people just get it wrong and you can root with a PC look in the guides section of the p9 lite fourms and you should find it there if not look.uo a guide on google it uses a pc but there is no way to do it on the device its self after you've flashed AND booted into nouget as twrp is not supported yet you had to flash nouget and then flash an elite kernel to get root after updating you'll have to either use a PC or wait.

No, I know how to root on MM, but I can't downgrade cause my NRD90M test-keys version is not official.
I did not use the classic TWPR.
I have the same version as you and I put on the recovery Revolution with the root revolution and everything works very well ...
You have to flash the recovery.img in fastboot and here you go!
If you can not root I think you can change Rom without problem

Can't remember off the top of my head because my mate 8 is not with me but I think L29 firmware should be compatible with your firmware also.

[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...

Yeah, downgrading to B160 should be a good choise..
Use then stock updater to look forward

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

Update P9 Lite from Android 6 to 7

Hello everyone, I have a P9 Lite which was issued from Vodafone Europe (originally VNS-L21C02B128), and I'd like to update it to Android 7.
Since none of the stock ROMs I tried would pass the verification when updating via the Project Menu, I found and flashed a newer Android 6 which works fine apparently - build number is currently VNS-L21C900B170.
Trouble is all of the newer ROMs are still not working. During the verification phase, it says they are not compatible with the phone.
Any ideas what is the simplest safest way to get to Android 7 ? Thanks for the help.

Have you tried Service ROMs?

- Unlock the bootloader
- on android 6 rebrand to C432 global
- in TWRP install fullOTA-MF-PV VNS-L21C432B370
- then you can upgrade to a higher version by installing a Service ROM via dload method (it will lock your BL again).
The problem is probably with your current build number - the C900 is fake firmware, incomplete or incompatible. I'm afraid you won't be able to unlock the bootloader or rebrand the phone with this build.
Hello Alf, I did try VNS-L21C02B346 but it didn't work, both with the original and the newer ROM. I also tried the "SERVICE Full Repair VNS-L21 C432B381" from here, also with no luck.
The current B170 ROM was labeled as "VNS-L21C432B170" on the site I got it from, but now it shows as C900. This one updated with no problems via the Project Menu upgrade command, the only one to work so far...
I will see later about unlocking the bootloader thanks.

You can't install C432 on C02 and vice versa without changing oeminfo, that's why you now have a C900 region and failed verification.
Thanks but I don't know hot to change oeminfo. Can I use SRK Tool ?
Also is there a free way to unlock the bootloader ? Is it this one ?
Does the phone have to be dissasembled, or is there a software method as well ?
Is dc-unlocker free for phones with android 6 and 7 ?
