My P9 was on an older Nougat version already, I can't remember which one.
Then i got a message there was a new version (L09C432B378) available.
Because my P9 was unlocked and rooted, OTA would not work, so i Googled a bit and found out that B386 was already available so i downloaded that version from here, unlocked with SRK tool and then my phone went into an eUpdate boot loop.
I put the downloaded firmware on an SD-card and installed it by pushing all buttons.
I was very happy the update went pretty well. Up untill the moment I wanted to pair my P9 with my headphones.
No go. I can't turn on Bluetooth on my P9.
When i tap the bluetooth switch, it looks like it is getting started, but after a a few seconds it is greyed out again.
Anybody here familiar with this problem? And is there a way to fix this?

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 guys, ive Just bought a P10 and it was on L09C02B161. Iwent on FF typed in vtr-l09 as model and persisted to check each one to my imei. I finally found VTR-L29C185B360 which said it was compatable so i did the proxy trick and i think it softbricked. Managed to sort that and its booting fine. It says emui 8.0 but its still on my old B161 in settings. Boot loader is now unlocked (with code).. TWRP would not install but the oreo one installed but doesnt seem to flash files they error. I just would like my old stock B161. Has anyone got any ideas? Thanks in advanced.
Hi all
I have re-posted this to the G7 plus forum, I mistakenly posted it in the G7 forum previously.
I have a Motorola G7 Plus XT1965-3 RETGB, after being pestererd by the update to android 10 mesage for several weeks, I finally agreed, since then, the phone fails to work with my in car head unit bluetooth connection.
It pairs, and will stream music from the phone through bluetooth to the head unit, just will not work as a hands free phone.
The head unint is a Kenwood DNX4230DAB, it shows the device connected as A2DP, but the phone (HFP) just shows connecting forever, before the update to Android 10, it worked flawlessly.
I've tried doing a full device reset, didn't help, and following various things posted on forums on the web, again no luck, the phone is unrooted, and the bootloader is locked, it is essentially as was when purchased other than the Android 10 OTA update.
Can anyone tell me is it poossible to roll back the Andoroid 10 update, I should never have done it in fairness, i've been bitten many times before with updates breaking stuff.
If anyone has any suggestions as to how to get the handsfree calling working again, or can offer a easy to follow guide on how to roll back to Android 9, I would be super grateful, I need to get the device working as a handsfree phone before I go back to work this week if at all possible.
Hoping someone can help.
I have an similar issue. On LOS17 the phone app works well with bluetooth but all the other voip apps like zoiper, bria or groundwire dont. the audio over bt is one way only
Regarding your issue: I afraid an OTA downgrade is not possible. However with fastboot you should be able to flash every stock you want as long as it is stock
Unfortunately, I tried to flash the stock Android 9 retgb rom, now the phone is a brick!
I wasn't aware that you need to unlock the bootloader before you flash the rom, so now it will no longer start

You only need to unlock the bootloader when you are downgrading or switching to another version, like from retus to retbra, saying this, you phone turns on? does it do anything? maybe you just need to flash the rom again, you can go here: https://mirrors.lolinet.com/firmware/moto/lake/ and find the firmware for your phone, you may have to flash it manually, i have tried to flash the firmware for my phone with RSD Lite but it says that its not in bootloader, if you are flashing the same build that you had or a higher build you dont need to have an unlocked bootloader, just check the dates and the build numbers to make sure that its the same you had or a higher one, just search how to manually flash it, if its really bricked, that it will not boot into bootloader, you can use blankflash to save it, just search on the forum
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
Hi all,
How are you?
I have spent soooo many hours trying to upgrade my new old stock Huawei P9 EVA-L09, its driving me absolutely crazy. When I bought it, like an idiot, I didn't check the Android Version, which I discovered was 6. So, I did oodles of research, gathered the right tools, downloaded the suggested updates and started.
I successfully upgraded to the latest android 6 (L09C432B210), but I tried many versions of Android 7, but to no avail. I eventually found a version of Android 7 called 'L09C432B322' that worked, but when I checked it says 'NRD90M test-keys', which is EMUI 5, Android 7; it is a fully functioning version of Android 7 but it is a pre-release version I believe, and neither the 'Files' option nor the 'Update' option are available on it, which is a pain. I have now tried a total of 23 different update versions, but no success, and with exactly the same issue with the update process, saying that it cannot update using that version (not precise wording!).
A couple of days ago I accidentally ended up on the phone update screen, the one with the big circle, while I was trying to get in to TWRP (fat fingers...). It sat there for an age doing absolutely nothing (aside from the circle spinning), not even failing, and I didnt even have an update file in 'dload' on my SD Card (not that I'm aware of), so I pressed the power button and shut it off. Now when I try to update, using either update.app via manual update or update.zip via HWOYA7, any update at all tbh, even old ones that I know failed but at least the update file was seen by the phone & process, it tells me the install failed and 'the update package does not exist'. I thought it may be a file extension association issue in Windows 10 (not sure how, just clutching at straws), so I reset the associations to Windows default, but that did not work. At around about the same time of the update issue starting, I couldn't say for sure when as I wasn't paying enough attention, I started using the HWOTA7 tool, which too gave the same result of 'the update package does not exist'.
Did HWOTA7 cause this? Did I cause this inadvertantly? Has a broken update.app caused this? I simply do not know and am hoping one of you fine people may be able to help me. Is the process looking in a different place to where either HWOTA7 puts the file (not changed from default) or where I put the file (SD Card 'dload')?
The reason I'm trying to update is because Android 7 is no longer supported by Google and one by one apps are disappearing from Google Play, so I'd like to update to Android 8 (Oreo). There lays another fine issue as I cannot find a version of it anywhere, not since Huawei removed the updates from its site a couple of years back. Not that any update will work of course...
I've never known a phone to be so difficult to get the correct software for and to ultimately upgrade. I even managed to update an LG G5 around 2 years ago when there were no official updates, but this Huawei P9 is just silly...
I think the update process should be this, update to the latest possible Android 6 then 7 for the P9, rebrand to the AL10 and, update to the chinese Oreo and then overlay the Kirin fix (I think); is that correct?
Thanks folks.
Paul.
Hey @vorlockfoss can you send me the B322 that you have found in order to update from B210 Marshmallow to Nougat?
Huawei's firmware servers were taken down only last quarter of 2020 so october/november/december 2020 around those months.
Hi W00fer,
How are you?
B322 is the version I downgraded from, back to C900B300. If you have B210 then you'll need B386;
HWOTA.zip | by Tecalote for P9
there are instructions in the folder. It includes the full firmware for EVA-L09 C432 B386 - for update from Android 6 to Android 7. For example from b182 or b210 to b386.

I've responded more completely to your other message, so if you need further advice it may be better to reply there and I'll do what I can to help. I will update this thread after we've finished, just to keep it tidy.
Thanks,
Paul.
