[Q] 4.4.4 bootloop - Nexus 4 Q&A, Help & Troubleshooting

Hi Guys,
I am pretty much stuck at updating my phone. I will explain the problem.
I got a Nexus 4 8gb version running 4.2. I recieved via OTA 4.3. Downloaded, installed no problem. After rebooting i got the 4.4. via OTA. Downloaded it and installed it Got stuck a starting apps, after 1.5h i shutdown the phone rebooted. Now it is stuck at the nexus logo.
I flashed via fastboot, i tried different official roms. The only one working is the JDQ39, i think 4.2.
I also tried flashing with the nexus root toolkit from wug... stil the same.
I can reach the fastboot and the recovery...
Any help???
Thx

i downgrade it to 4.2.2. But my imei is gone and i cant make any call.

Nexus 7 4.4.2 update

For the life of me I cant get 4.4.2 to install/boot on my nexus 7 2012 wifi
Wondering if there is a stock rooted zip out there so i can just flash it and be done with it.
Ive:
wiped
locked/unlocked bootloader
flashed the stock image (installs/boots but doesnt start) 'com.google.settings' fails at start.
flashed 4.4 image and tried to update via OTA (fails)
flash 4.4 and tried to sideload the update in stock recovery (failed, unexpected contents in system/google email)
flash 4.4 and tried to install update viz TWRP...failed
running out of ideas. My last hope is a 4,4,2 stock rooted rom i can just flash via twrp. but there doent seem to be one.
found one for my n10/n5, but not my n7 (2012 wifi)
any leads?

After flashing 4.4.4, I cannot boot my phone.

I was using 4.4.2, rooted. I used SuperSU to unroot and tried OTA, but it failed and went back to 4.4.2. So I did a factory reset. It was weird that it still failed at upgrading to 4.4.3.
Then I downloaded the official 4.4.4 image from Google and flashed it to my phone via USB. In the cmd everything was OKay and the phone stated rebooting, but it won't go past where the four colored dots are merging (after the Google logo, and they look like they bouncing).
Please help!! Is it because I skipped 4.4.3?
No, this issue is not caused by skipping 4.4.3. It is somehow a software issue, many people have weird problems updating to 4.4.4, too. Try to flash a factory image of a older version like 4.4.2 or even 4.3. That should let your device boot again.

Nexus 4 wont flash beyond 4.2.2

So I rooted my N4 while on 4.4 and installed a custom kernel for battery improvement .. it was francos kernel. I didn't unroot it ... then ...
Then I tried to update to Lolipop and it got stuck at logo. I've tried every flash I can find ... only 4.2.0 and 4.2.2 will take. Then after adding a sim and rebooting it gets stuck on logo again. Or if I click the OTA update it gets stuck on logo.
I've tried a lot of options in the nexus root toolkit.
Maybe I have the wrong radio or kernel for anything beyond 4.2?!?!
Please, any help would be appreciated.

Click to expand...
Click to collapse
BTW: when I attempt an OTA update from 4.2.2 to 4.3 it gets stuck at "Android is upgrading ... starting apps"
I think the baseband/radio is not flashing when I do "flash stock + unroot"
Any help?
Are you using the correct bootloader?
Many ROMs don't come with the bootloader and radio image. Even flashable stock ROMs.
If you want the latest lollipop I suggest this thread
http://forum.xda-developers.com/nexus-4/development/rom-stock-flashable-rom-t3084656
When I set up my device from scratch I did the following:
- format system, data, cache, dalvik in TWRP
- flash bootloader in TWRP
- flash radio in TWRP
- flash ROM in TWRP
- flash SuperSU in TWRP
- reboot
First reboot can take really long (up to 10 minutes may be normal still).

I'd recommend you to flash factory image instead, with fastboot.
This will give you a clean system without problems.

SM-N910F Won't boot

Hi,
My SM-N910F wont boot. I have tried to flash a stock rom through Odin, and the flash is successful but when the phone boots up it just says "System UI has stopped" with a black screen.
I messed it up by flashing both modem and bootloader wrongly, then wanting to reset it by flashing stock firmware, but it won't work.
Edit:
I have flashed twrp and managed to factory reset, and it boots now. But now I have another issue, it restarts every 30 seconds, can't even get past set-up.
Edit2:
I have fixed it. I flashed the right modem and a bootloader update and it no longer restarts.
Would appreciate any help.
Thanks.
Help with what?

Stuck on AT&T Logo

Hello all!
I am trying to get my s4 back to working conditions. Earlier last night i went within SuperSu and did the full unroot then I restarted the device. When i restarted the device i was stuck on the AT&T logo. I tried to go into recovery but somehow twrp was deleted. I have been having issues flashing twrp back onto the device. Does anyone know a way to help me unbrick my phone?
:fingers-crossed::fingers-crossed:
Note device is using 5.0.1...cant remember if its stock or custom. But im pretty sure its just a stock rooted phone.
You can't flash TWRP when the phone is running a stock 5.01 bootloader.
