[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

Full Disk Encryption hangs for hours on rooted SM-910C

update, read at the bottom.
Hi, I have a Samsung Galaxy Note 4 SM-910C which I have rooted after flashing a stock Samsung rom. If I recall correctly, I flashed a stock android 4 rom trough ODIN, did it a CF-Auto-Root and eventually updated android 5 through wifi (OTA). SuperSU was installed.
I have attempted to do a native full-disk encryption trough the default Security menu; the phone went into a black screen with a green outline android robot in the center, with no progress bar or text of any kind (I found the image online, but can't post it due to account lack of privilege) . It has been on this same screen for over 8 hours now.
The device was NOT in USB-debugging mode.
What are your suggestions? Should I try some kind of reset? Is it possible the process will resume and is taking so long due to the amount of files? Or I shouldn't expect it to work since I tried encrypting a rooted device?
I'm not worried about any files in it, but I'd like to make sure to be able to recover the phone without bricking it. I'll be leaving the phone plugged to the outlet and untouched for the foreseeable future...
Thank you very much.
UPDATE: I powered off the device (had to remove the battery) and when turned it on again was met with the "Encryption unsuccessful" screen. Then I turned it off and went into recovery mode by pressing and holding POWER+VOLUME UP+HOME. Even tough it displayed a warning - dm-verity verification failed - I chose wipe/factory reset and then rebooted the system and it seems to have worked fine. After the start splash screen and a notification that is was installing applications (bloatware), it brought me the Welcome to Samsung Galaxy configuration wizard.

Issues after the 6.0.1 update

I'm on Telus, with a Galaxy Note 4 and the recent software update to 6.0.1 ****ed up my phone. It wouldn't install correctly and it finally went through the third time through OTA. I've done a hard factory reset through the recovery menu, and flashed the firmware on it through Kies and Odin multiple times. Cleared the cache. It's still having issues. Slow, laggy, and high battery drain. The OS seems sort of okay if I'm booted but it but it's a little slow. Soon after turning the screen off, I won't be able to turn the screen back on, and I end up having to pull the battery. It will restart randomly and I'm not able to turn it on 9/10 times, with 5 of those going to a emmc_read error download screen.
Do you guys have any recommendations on what to do? I haven't tried a custom recovery so far.

Very strange booting problem with my samsung galaxy S5 (SM-G900F)

Hello,
I hope someone can solve this problem for me. On a day i wanted to check my phone and I saw only the logoscreen of samsung. My first reaction was to pull the battery out and put it back in. So I restarted my phone but it was not going further dan the logoscreen of samsung and always kept restarting automatically. The very strange thing is when I remove the battery for more than 15 minutes and than put the battery again in the phone and push on the power button it starts with no problems. When the phone is completely started and I restart the phone manually the problem comes back again and the screen is not going further than the logoscreen of samsung and keeps restarting all the time automatically. The phone is 2,5 years old and I used it daily
What I already tried to solve the problem:
- Reset factory settings and wipe cache partition with the "power, volume up and home button"
- Installed firmware from sammobile with odin (firmware completed but still automatically restarting at logoscreen)
- Blew the powerbutton with air
- Rooted the phone with Kingo Root
I hope someone can help me? Dont know what I can do more

The problem with rooting is that it sometimes has to restart the phone and then I have to problem again that it is not going further than the logoscreen. How do you root? Do you have a guide?

Most probably motherboard issue and should be replaced if possible ,had same issue on s7edge with random reboots ,shutdown not turning on ect

Hi guys, regarding the restarting issue...have some “improvements” after deleting data in apps...phone and device maintenance....15 hours without restarting..fingers crossed

Hi guys....the restarts have become too much to the point the phone is unusable...its worse when the phone is on 4G/LTE...Sometimes the screen goes dark and the phone becomes unresponsive.
My effort to take to the Samsung centre for repair has been in vain...as I bought the phone overseas and the warranty is not honored here.
Any help will be appreciated...
