Hi, I have a P9 Plus with firmware VIE-AL10C00B183 and unlocked bootloader. I have TWRP installed.
I'd like to upgrade the phone to nougat. I don't care if TWRP is removed and the phone locked again in the process.
How can I do that?
Thank for your help

Hi everyone!. I purchased my Huawei P9 dual sim (Chinese Version- AL00) 2 weeks ago. I unlocked its bootloader and changed OEM to EVA-AL19C636 and flashed Nougat Beta. Then I reflashed back to EMUI 4.1 (AL19C636B190) but I forgot to flash HUAWEI P9 Rollback Package (EVA-L19, from EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0, C900B300). Everything flashed OK, the phone restarted but there is a bootloop at Huawei logo. It cannot be turned off. No recovery,no download mode, cannot force updat, nothing except fastboot. Bootloader is locked again and I cannot unlock it (though I have unlock code). I tried many times but no success. There is always an error:
"FAILED: Remote: Command not allowed"
I can't flash anything using fastboot.
Anybody helps me!. I really need help. Plz!

As I said, I changed it into EVA-AL19C636 then updated to Nougat, not AL00 updated to Nougat.
There is no problems with EMUI 5.0 but I want to have rooted firmware so I returned to EMUI 4.1. But .....I'm facing with my problem
Anyone can help me?

You have to change the oem.info into Al19 (using SRK tool) then flash Al19 rom.
hi ledinhbac
I experienced the similar issue with you. I rollback to EMUI 4.1 (AL19C636B190) directly from (L19C636B190) by flashing a HUAWEI P9 Rollback Package (EVA-L19, from EMUI5.0+Android7.0 rollback to EMUI4.1+Android 6.0, C900B300) instead of updating to L19C636B361. [ wrong SD card inserted].
My phone restarted but there is a bootloop at Huawei logo. It cannot be turned off. It can only go into fastboot mode. Bootloader is locked and I cannot unlock it (though I havent unlock code). I tried
There is always an error:
"FAILED: Remote: Command not allowed"
Could you solve the above situation?
Hello guys! it's possible? there's a safe method to do this without restore phone or unlock bootloader?
I have VTR-L29-C636-B120 and there's no OTA updates u.u I want that B151 firmware from C432. Thanks in advance and have a nice day!.
Hi there,
Same here have also C636B120 firmware and no OTA. Any tips or advices?
Thanks
Tom
You can only rebrand your phone with TWRP. For this you need an unlocked bootloader and the unlock progress causes a factory reset.
So, without factory reset you can't rebrand your phone to C432.
If you installed a C432 firmware you can relock you bootloader, but I don't know if the OTA Updater recognize a different between locked and relocked.
You can try this. It worked for me as Updater very good, because I can't OTA update because, I rooted. But this tool has also a rebrand option. If you need any help using this, reply or send me a message.

There are different custs, different builds. How could people help you if you don't provide crucial info, what exactly is your firmware - like EVA-L09 c432 b394 or what
Hi All,
As you know they already released the Official Android 9.0 Pie for Huawei P20 Pro in EU.
I have the previous version of Android 8.1 CLT-L29.
My devices is:
-Rooted
-Bootloader unlocked.
Can I update via OTA to Android 9.0?
Is there any problem during the upgrade?
Will be still rooted and bootloader will be still unlocked?
If not what is method to do upgrade and still have a Root?
Thanks for your help!
You need to flash stock recovery first.
You will not continue to rooted.
Your bootloader will remain unlocked
Thanks for your kind answer.
Do you think should I update to 9.0 or should I stay with the previous version?
I am not that sure about the root process at the moment and I don't want to loose it.
I don't think there are that many new noticeable features. EMUI looks and behaves pretty much the same.
Hello everyone,
I recently wanted to upgrade my Stock P9 Plus from Android 6.0 EMUI 4.1.1 to at least Android 8. I unlocked the Bootloader with DC-Unlocker, installed TWRP and tried Openkirin. It didn't work and now my Phone doesn't boot because there is no valid OS installed.
Im searching for a stock ROM for my VIE-L09 that returns my phone to the factory version.
I'd also be interested in installing a custom ROM, but i didn't find anything that works.
Please help me.
