Hi all
I picked up a second hand Huawei P9, (EVA-L19) my intention was to unlock the bootloader & flash a custom version of Android 9 or 10 on it.
I unlocked the bootloader via the DC method, and loaded TWRP, and wiped the previous firmware...
Only during the process, I realised I needed to update the phone to the latest stock version of Nougat first, and then upgrade it to Oreo, and then load the custom firmware... I have struggled to find stock software that works. I have used TWRP, the multi tool, and other programs such as firmware extractor, the HUR updater and I just cannot find anything 100% working. On top of that, there seems to be a problem with the battery, not sure if it is firmware related, or I need to get a new battery. The phone stays on for 2 minutes before the battery dies.
I have managed with the HUR updater & huawei-firmware.com to get a version of Nougat installed, it seems to boot, but the keyboard doesn't work, and any attempt to reset it gives me the explanation mark in the recovery menu.
The phone is a South African version of the L19.
My intention would be to get the phone back to working version of stock, then follow the correct proceedures, and update to Oreo, and then custom again. If the battery still gives issues, I will replace it.
Please help, running out of patience.
Thanks

I recently upgraded to EMUI 5.0 but it was a little buggy so I decided to downgrade.
I found this website that I can't show because this website won't let me put it in, that 'showed' me how to downgrade back to Marshmallow but as I was doing it my device for soft-bricked and now I am in a boot loop and none of the recovery options work. Also cannot erase all data (it fails every time I try)
I would be really happy if I could get my phone back to how it use to be.
P.S. I have a backup of all my files so I don't mind what happens to my data on the phone.
Hello, I have a huawei p9 L-19 and the problem is that after i attempted to unlock and root my device the phone stayed on firmware B360 whatever i do. And i can't install any software which is not related to android 7 otherwise it fails.
This problem occurred when i tried to install twrp . After installing the phone was blocked into now booting or something like that.However after a couple of restarts the phone booted and there was no problem. I triyed a second time to install twrp and failed again, so i tried relocking my device, and when i first booted i realized that i have no keyboard installed except google voice, so i configured the phone after the first boot ,and i realized that all the huawei apps are gone, such as clock, backup, camera.
I believe this problem is based on the fact that the twrp was for android 6 and i was on android 7.allthough The weirdest part is the weirdest part is that whatever firmware i install, it either fails or it doesen't change the current one B360.
Please guys i need someone to help me with this matter, i just bought my huawei p9 :crying:
Stupid me installed EVA-C900B166 on my P9 and now my Android Pay doesn't work. I don't remember what the prior version was but I tried to install the UK/EU P9 rom with the hope that this would fix the issue. But no luck. Is the feature now broken and I'll never be able to repair? I was hoping to flash a stock rom from the Huawei site. I dropped the file into the dload folder went through the various update steps which looked like it was all was fine but when the phone restarted is still had version B166.
Love my phone but getting fed-up waiting on the never arriving update
Any tips on reverting or even just making Android Pay work would be much appreciated.

Does NCF work ? Try installing an EVAL-L09 Rom via twrp.
Hi. Im Huawei p9 user. I got this as gift. Its from South Africa (according to Huawei customer care). My phone build number EVA-L19C185B397. problem I'm facing is: i cant update further though ive an official update of B401 pop up in my phone updater.
Each time i try to update, it fails at 5% (update downloads, phone restart, update screen appears). I tried dload method, but same result.
Note: i tried to root once. unlocked bootloader, tried to install TWRP. But unable boot into TWRP. After that this problem started. Then i relocked bootloader. as a result lost camera app & other functionalities in setting. but problem continued. Plz help somebody.................
there are zillions of threads on how to install stock rom...
i can see u know ur way around bootloaders and recoveries so restoring ur firmware shouldnt be a problem

So I had the phone for almost 2 years, and I realise that I haven't received updates since March 2020. I know that EMUI 11 is out, but I have not gotten an update after EMUI 10.0. I tried using the HiCare method, the HiSuite PC method, but nothing works. I'm currently located in the United States, I don't think it has to do where I am, because I know someone who has EMUI 10.1 or EMUI 11 on their device. What should I do to update the device? I also found out the region code is C636, which is Asia Pacific.
There's a thread on flashing firmware on locked boot loaders. That may be of help.

I would do it, but I think it's too risky.
Been there, done that. Don't worry, I can help for you not to kill the phone like I did on my first attempt .
The dload method works fine. Although, you will need to get the rom for our region from here (this is the latest 10.1 version, you can verify it here) . I recommend going with the OTG adapter + USB memory stick method (it will wipe the data so don't forget to make a backup before proceeding).
I just want to clarify that I haven't been able to upgrade from 10.1 to 11 with any of the methods you have mentioned, not even with HISuite Proxy (there's no dload FW support for EMUI 11). Since I'm a Mac user I had to go with a virtual machine so that could have been the problem though (I read other users have successfully upgraded to 11 once they were on 10.1).
The main reason for me to update the phone was fixing the wireless charging. I've bought a Huawei wireless charger and I'm having this issue (spoilers alert: it doesn't seem to be a software issue so no, still not working).
The process is relatively safe as long as you flash the right firmware. On my first attempt I flashed the firmware from a different region. The phone worked normally except for the device certification (no Netflix, Google Pay, banking apps and so on).
Good luck and just let me know if you have any questions.
Did you succeed to upgrade your device to emui 11? Please share your method if you did
Try to update via Hi Care (it used to be to force an update to Emui 11 before the update came out in the normal "updater")
In HiCare app -> select Your device -> Quic Services -> Update -> click Check for updates
