[Q] Nexus 4 Blank Screen After 4.2.2 Update

Hi There,
Shortly after updating my Nexus 4 to 4.2.2 OTA today the screen went blank and I've been unable to get it to function correctly again.
The phone is still showing some signs of life, I am getting notification LEDs and I am unable to unlock the phone with facial recognition even though the screen remains blank - I can tell from the vibration and the LED stopping that it has unlocked. Pressing the power button to lock it starts the notification LED again.
I have tried a hard boot (Volume Down + Power) and the screen did come on to display the google logo followed by the X but as soon as they had been shown it returned to a blank screen.
Does anybody have any ideas of what this could be or how to solve it or should I contact Google in regards to this issue?
Thanks in advance for any help

seems like the OTA update has corrupted somewhere. You should reboot into bootloader and use fastboot to flash the stock 4.2.2

Is there anything else worth trying before doing that? I wouldn't have a clue where to start as this is my first android device

Ok so I got it working but did lose all my data. If anyone else comes across this issue I had to boot into recovery mode and do a full wipe/factory reset. The first time i did this the phone started up with no problems but during configuration when I entered my Google account the blank screen strangely returned so I again did a full wipe in recovery mode, skipped the 'set-up google account' step and then entered it manually later in settings once the device had started up.
No idea what caused this and if its a bug in 4.2.2 or an issue with some settings in my google account that are being backed up and restored to the phone but either way I had no problems until 4.2.2 update installed and the issue occuring even after first data wipe rules out any third party apps being the cause.

I had a similar problem after updaing that the screen stay blank and it wo'nt unlock
As soon as i disable the bluetooth the problem solved.
It's happened when i paired it with my pc

HELP PLEASE - Weardest problem i've ever had

hi everyone. I've ruined my phone by restoring a backup and the phone kept saying "unfortunately process Phone has stopped" - "unfortunately process com.android.phone has stopped" - "unfortunately process contact storage" has stopped' and many more... it shows status bar and NAV-buttons and connects to the network for 0.2 seconds and instantly disconnects and then it happens again. i don't even get to go to the home screen. i tried factory reset but didn't work, Tried flashable zips of stock rom but nothing changed, flashing a clean stock KDZ won't even work(even CSE flash mode), my phone doesn't go to recovery mode(TWRP or Stock) either. what i think the problem originates from is a couple of files in the data partition that are still left over or some integrated updates to the system... or maybe the partitions are harmed
one thing that you might wanna know is that every time i re-flash a KDZ and it boots up, it shows the 'android is upgrading' - 'optimizing app X of Y' page, though it shouldn't. and after showing the massages of ' ... process has stopped' after a couple of minutes it restarts and it goes over the process again....
I've un-destroyed my phone a lot of time but this is different, it's like the flashing and restoring doesn't actually do anything and just moves a progress bar but doesn't do anything, I'm on stock recovery and stock rom(which doesn't boot or go to the recovery mode). PLEASE HELP ME. My phone is n a dramatic situation :crying: :crying: :crying: :crying:

Is there any way to modify partitions from download mode?????

Anyone ?????? Please help... I have serious problem, my phone is dead

XT1564 unable to reboot properly for OTA

I have a stock moto x play whose hardware sku is XT1564. It's on android ver 5.1.1 and system version is 23.21.25.lux_lra.en.US
I have not performed any soft mods or alterations, be it root or bl unlocking.
The only thing that I would think is different than normal is that the phone is encrypted, so it asks for password whenever it boots up.
I got a notification to update to 24.74.5.en.US a few days ago and decided to try doing it today.
It downloads the update fine and when I press on the notification for it to start the update process where it says it needs to perform a reboot to update it goes into a "phone will reboot in 10 seconds" screen and when countdown finished it shows the "shutting down..." popup that appreas when you try to shutdown the phone.
Then the phone stays with that popup until it finally shutsdown like 4 minutes later on what appears to be a hard shutdown because it doesn't reboot. I have to manually power it on and then the phone starts up normally asks me for my password and about a minute after android fully loads the phone tries to shutdown again without any input. And then it just keeps doing that until I boot the phone into fastboot and try to get it to bootloader, where it shows the dead android logo with a red yield sign and promptly shutsdown. Then when I start the phone normally it shows an "update unsuccessful" screen.
Anyone have any idea what might be the problem?
I've been thinking it might be the encryption but IDK. Also I've checked the thread with the firmware versions and couldn't find mine there. Is there a way I could dump mine for backup in case I **** something up trying to get OTA to work.(without unlocking bootloader and rooting, of course)

Now the update has stopped appearing and I can't get it to recognize there being an update for this device.
Fudge!

My 6P is on a bootloop

Hi,
I was using my phone when it suddenly turned off and got stuck on a bootloop, every time the bootup stops a the white Google logo at the start. I accessed Fastboot and can't do anything beyond that, it doesn't launch recovery. I tried to flash it with the latest google images but to no avail, the process goes as usual but when the phone restarts it gets stuck gain.
What should I do? Is this the Nexus 6P's bootloop problem I've been reading about on some blogs?

Yes, BLOD and no recovery mode. It is a hardware issue. Nothing can be done from a software/flashing perspective. Hopefully you have a warranty of some type. Otherwise it's time for a new phone.

Black screen bootloader and constant hard freezes

If I have my phone off, and power it on it will boot straight into the bootloader but have a black screen, if I press the powerbutton I assume I am choosing "resume poweron" because the phone restarts and then powers up with a black screen for 30 seconds before the animated part of the boot animation starts.
I have done a full reflash(afaik) from LOLINET using my device model file XT1926-5 and my region RETAPAC and when I reboot it still has the black screen.
I have Magisk installed and I believe my bootloader is unlocked, the only thing I remember doing was trying to flash TWRP but I have done a full restore since then using LOLINET.
Usually a black screen like this wouldn't be a problem, however the real annoyance is my phone constantly will freeze up for no reason, I will be mid way writing a message and the whole phone will hard freeze, I have tried doing another restore to see if this will fix it and alas it has not, so I am at a loss to what is going on, I have booted into TWRP and tried repairing partitons thinking something could be flipped and it was angry but no.
So I am a tad bit out of ideas unless anyone has anything for me? Logcat doesn't turn up anything interesting reguarding the crashes, I haven't found any events that are logged with ERROR,ASSERT or WARNING at the time of crash.
Anyone got something for me?

Are you able to get in recovery mode, or the bootloader just freeze.

If I try go to recovery it falls through tight away to the boot loader

Even if I use adb reboot recovery it just reboots into the black screen fastboot.
