So recently I updated my phone using the Firmware Finder but flashed an NRD90M Test-Keys. Read about it and the only way to fix it is to flash twrp and flash another firmware. Tried to flash twrp but got an 'FAILED (remote: Command not allowed)' error. So that didn't work and I tried to factory reset my phone using the stock recovery but that gets stuck on 7/10% and it then gives me an error. (Just a big red '!' mark and says Failed.)
And after the failed reset the phone doesn't have a keyboard. Only the voice typing from google. So trying to even set up the phone makes it a pain in the ass.
I can get into fastboot but trying to flash anything gives me the (Failed (Remote: Command not allowed) error.
My phone is unlocked. It only says that FRP is Locked.
Can anyone help me with this issue?

no .... is there any way to unlock the bootloader for fastboot commands?
Hi,
I was unlocked and rooted and I tried using the NRT to flash the M system image. It worked and I got the phone to boot once. It went through the Android is upgrading process and I used it for a few seconds and then it froze. I rebooted it by holding the power button. It now will not leave the bootloader. When I try to start it just flashes back into the bootloader. In the BL log it says "failed to validate boot image: ref=-1" So I tried re-flashing both manually and in the NRT. This is the error I get when flashing
(bootloader) failed to write primary GPT
(bootlaoder) failed to flash partition
FAILED (remote failure)
Any help would be appreciated.
Thanks
Try fastboot erase before fastboot flash

Stop using a toolkit and do it manually https://developers.google.com/android/nexus/images?hl=en
I said that I did it both manually and with the toolkit. Sorry you feel that since I didn't want to type all that in you are better than me. I figured it out though. I couldn't get into any recovery so I used the toolkit to boot into the temporary twrp. Formatted all the partitions and got it to flash successfully.
From what I can tell it tried encrypting and it ruined the partitions.
My nexus 6 received the update by ota and I have experienced the same thing.... Tech support was no help telling me to go to a sprint store. I'm not sure what caused the issues here... My phone did the normal Android is upgrading thing and and I left I to do its thing it booted up and I used to it. Make a phone call. After the call my phone froze when I tried to open all apps. I restarted the phone in the same way the first post did. How ever my phone booted up to the new Android boot screen , however the phone restarted again and this time into the bootloader. Can anyone help me with this?
Hi,
my friend has replaced the screen of his XT1072. Now the phone is stuck in a bootloop. He has never experimented with custom ROMs etc., so the developer options are disabled (no ADB, no unlock allowed). I can access the bootloader (locked, status 0) and connect via fastboot. Here is what I have tried so far:
select the "Recovery" option of the bootloader: immediately reboots into bootloop
fastboot oem unlock: not allowed (developer option not set)
flash CWM: Preflash validation failed
flash stock rom (as described here): Preflash validation failed
Are there typical hardware issues (forgotten connectors etc.) when replacing the screen of this phone? I don't know if it is a software problem, but what I find quite confusing is that the "Recovery" option of the bootloader does not do anything - not even before I tried the flashing stuff.
Any other ideas how I can get this thing running?
EDIT: I finally managed to flash the stock image. First I tried with fastboot on linux, then with mfastboot on windows. I also tried different images - probably the "Preflash validation failed" error was because of a wrong image. Still bootlooping and recovery option functionless.
long story short, my relative came to me for help after he decided to install a new ROM and made a simple error of forgetting about the OEM unlock option in the settings menu beforehand. an error occurred along the way and he tried to go back to stock. now when the phone boots it goes into the bootloader (which is locked) and gives a start up failed message saying to use Software Repair Assistant.
trying to go into recovery gives a
Code:
AP Fastboot Flash Mode [Secure]
Fastboot Reason: UTAG *bootmode* configured as fastboot
failed to validate system image
ERROR : Failed to pass validation. backup to fastboot
Boot up failed
i tried flashing TWRP but its giving errors too. are there any known workarounds to unlocking the bootloader or forcing a recovery/twrp to work?
thanks, all
Hi
I bricked my p9. I tried to force update(3 button method) but it always fails at 5% saying that it is an incorrect version.
I can go in fastboot mode but I can't write anything to my phone it says 'FAILED (remote: Command not allowed)'
Does anyone know a solution? My bootloader is unlocked.
Thx in advance!

You could probably get a better help if you describe what was your existing firmware version (like L09c432b386 or so) and which one you tried to install by dload
Try to unlock again. I had a bug when it said my bootloader is unlocked, but it was locked.
