P9 Lite softbricked

Hey guys!
My Hardware:
Huawei VNS-L21
Windows PC
I've flashed the oeminfo of a Huawei VNS-L31 on my VNS-L21 (followed this guide: http://www.htcmania.com/showpost.php?p=23861935&postcount=2) and after that, I've installed B100 rom via DLOAD-Method. Everything worked fine. Then I wantet to upgrade to Nougat (B336), so I downloaded the ROM and the L31 Data (because I've previously flashed the oeminfo of a VNS-L31, mentioned before). I've done that in the Revolution recovery b. 8. Flashing the main system worked fine, but flashing the data failed. I don't know why (maybe I didn't have enugh patience) but I rebootet anyway. Now I have the problem that I can neither boot to the system nor boot to recovery. However, I am able to access fastboot and I am able to flash recovery, system, cust and boot. I've tried flashing the B336 rom via fastboot (flashing system.img, boot.img, recovery and recovery2 from the extracted firmware and cust.img from the extracted data folder), but I'm still not able to boot. My phone is stuck in the "Your device has been unlocked and can't be trusted" screen as seen in the attachment. I've tried meticulu's twrp and revolution recovery, they also fail to boot (I also get to the "Your device has been unlocked and can't be trusted" screen.)
Hopefully you can help me.
Best regards,

Doesn't work, I've tried that several times

Try to get a recovery running.
So try to flash different recoveries (Meticulus TWRP or Revolution Recovery) with fastboot (fastboot flash recovery *.img)
Flashing N recovery like this *should* work.
Report back then for next steps.

I've tried Revolution recovery and meticulu's TWRP, both don't seem to work. When I try to boot to recovery I do get the "Your device has been unlocked.." screen...

Try download any ota update with firmware finder, extract the recovery.img from ota You have downloaded (You can extract it with Huawei extract tool), flash the extracted recovery with fastboot, put the update.app on dload folder in the Root of sdcard and flash it with the 3 keys method.
You will be able to successfully install the ota only if you extract recovery from ota You whant to install. Don't skip the extracting recovery step! If the ota install 100% and the phone stays again in bootloop, restart the phone into recovery mode (press the volume up + power key at the same time while the phone bootloops till will turn off and power up again, when the phone start up quickly release the keys) do a factory reset and wipe cache.

[Q] Bricked P9-lite VNS-L21, no vendor, version and product partition

While rolling back from N to MM my phone started bootlooping. I was facing this problem few times so I thought I could fix it like always. But there is one problem. I'm unable to flash any rom from fastboot or recovery. The only recovery that works is Nougat Revolution Recovery. When I try to flash I get errors and info: failed to mount version / vendor / product. I wanted to wipe those partitions but they are gone....
Does anyone know what to do? I'm pretty much clueless now...

1st,wipe system, boot. extract update app with huawei update extractor. go to custom recovery, flash stock boot IMG and stock recovery IMG. Power off, use three button dload method, reboot, when booting press vol up for three second, now you are in e-recovery. Press shutdown. Press and hold power and vol up for stock recovery. Do factory reset. If need do the factory reset 2/3 times. Now you are with locked bootloader.

2) download HUAWEI Multi-Tool
3) extract 2 UPDATE.APP files from zip files of stock rom
4) extract image files from the large UPDATE.APP file by HUAWEI Multi-Tool -> Unbrick -> Launch Huawei Update Extractor
5) boot the phone into fastboot mode by power / vol - and connect the phone to PC
6) HUAWEI Multi-Tool -> Unbrick ... flash everything
7) copy the large UPDATE.APP file to SD\dload and reboot with power / vol + / vol - ... phone installs update
8) copy the small UPDATE.APP file to SD\dload and reboot with power / vol + / vol - ... phone installs update

bootloop and can't access recovery

hi guys i tried to flash my C9000 but now my phone is in bootloop and i can't enter recovery it says
recovery booting
recovery is not seandroid enforcing
set warranty bit recovery what to do plz help
i tried skyneel .com guide
i flashed twrp on my phone

Hi bro. İ have same problem 8 months ago and i know this fix.
First. Sorry for my bad english.
You must wait the battery fully discharge. Because you cant make anything now.
When fully discharged phone. You plug charge and press wolume down+power+home. You can go to download mode this way. You must flash the original firmware via odin.
And if you want flash twrp again this step is required.
Go Settings page in odin and untick the auto reboot.
And manually go to recovery mode by download menu after install.

Ok, do the 3button combination as if you are booting into download mode. As soon as screen goes black, keep power and home key pressed down but move to volume up. You have to be quick before it boots to download. This will get you to recovery.

Hi dude,
if you're on stock rom try this:
reboot in bootloader/fastboot mode, connect the device to your PC,
open the prompt and type fastboot reboot.... you should solve.
Instead if you're on custom rom let me know.
If you installed some software/app and stucked into bootlooping,
you should be aware of which app you installed last and booting in recovery mode (TWRP)
try to delete it manually.
Cheers

Well

Thats the problem.
I can enter in the bootloader, the phone have the TWRP, are now whats happen but i can enter in the custom recovery.
The screen turns black and grey.
youtube com/watch?v=h9oMBpD0MZQ&feature=youtu.be
The phone dont have a custom rom, is the stock rom.
I erase the system and data in the TWRP, because a problem with my google acount in the phone. but it was worse for the phone.
The only thing i have to do is enter in the stock recovery, and the software installer(vol+ vol - and power).
I cant use the ADB minimal and fastboot. The phone is reconized by the PC, but the program no.
I think this is the only possibility, i download many firnwares, but in all the screen shows "Software install failed incompatible with current version"
In the 3% or 10%.

Wow, you erased system and data ? that's the reason because it will not boot dude.
Fortunately fastboot mode and twrp works and i think that will help you
bring your device back to life.
Do you remember latest firmware of your device ?
Which TWRP version are on ?

mmm

The Phone model are G9. A P9 Lite G9. Is a VNS-L22 of latin america(i think).
And the phone is in Android 6.0 stock, and the TWRP version is 3.1.0-2
Fastboot mode ?
The vol + vol - and power combination ?
And no, the TWRP dont works, dont enter in there. The phone stucks entering in the custom recovery. But the stock recovery works. The custom no, the stock yes.

You flashed the TWRP but don't work ?
Fastboot mode is bootloader mode so.....
what happen if you turn off the device and restart it
holding vol - and power button until it boot into system/bootloader ?
And vol + vol - and power buttons = three buttons aka DLOAD method are used to flash a firmware
but only in android 6.
Without know the latest firmware you was running on your device
it's very difficult to revive the phone, regardless of the type of device...
Another way to try to revive the phone is a rebrand but it is a bit difficult
and you need the correct files with a working TWRP...
Sorry dude i think i cannot help you anymore...
I wish you the best
