[Q] Help! Nexus 4 stuck in bootloop after 4.4 update.

Hi guys,
I tried to update my Nexus 4 to 4.4 when Google pushed the update out for it yesterday, I forgot I had unlocked the phone (I don't have any custom ROMs on it, just SuperSU.)
Every time I try and power it on, the loading screen is endless, although I can hold power and volume down to enter recovery mode, nothing seems to be working.
I am a bit of a novice so any help or suggestions would be really appreciated!
Thanks.

The first few pages of the forum is littered with posts like this, i was in the same situation.
What i did was download the 4.3 rom from google, and flash /boot and /system onto the phone. I suspect the 4.4 rom would also work.
This got the phone booting without harming (most of) my data, but much of the UI was mangled and didnt work properly. I tried to backup my images over USB but it didnt work, you might have a better result. I also wanted to backup my SMS but they had all vanished.
I rebooted the phone to recovery (TWRP) and used adb to backup the sdcard (adb pull /sdcard sdcard) then did a full flash using the 4.4 rom downloaded from google and that got it working again. Then i reflashed the latest version of TWRP recovery and SuperSU.
Hope that helps.

That's really helpful, thanks! Is there ANY chance of a step-by-step? I'm a complete 'noob' probably a mistake to root in the first place :crying:
If you're busy don't worry, just don't want to **** things up more than I have haha.
Thanks, appreciate it.

Cheers guys, a lot more helpful than the bloke from Google. Will try it in the morning!

This will surely help
If somebody is facing boot loop after kitkat update on nexus 4 and no data backup can try to go to safe mode and backup their data. To goto safe mode on boot screen just keep pressing up and down volume button for some time phone will get into safe mode and can be backed up.

Hi,
It also happened to me, dont know if it is related to having ROOT or not, but i had to manually flash factory image (4.4) and it worked. I flashed everything except userimage.img but on first boot it took like 15 minutes to reboot and then all my personal data (photo, music...) was gone....
So just be cautious before upgrading!

Yeah that is pretty much what I did to fix mine except that I did not flash the userdata (step 10 in chapter D) so that I would't loose my data.

I had sideloaded a rom in recovery so that it will replace the lost system.img on my phone. Then, it booted up and I flashed back factory images the usual way. Everything is running smoothly again.

This is sideload guide. And the is the rom I used to sideload before: Purity. After I had successfully booted into the system. I flashed 4.4 factory images using this awesome noob friendly guide for a clean kitkat update.

Installing the driver. Refer to this thread http://forum.xda-developers.com/showthread.php?t=1992345
Boot to bootloader and connect to your PC, usually Windows will find the driver automatically

Well, if you can still get into recovery, just sideload a rom back in.

[Q] Help! Phone bricked itself trying to update. Factory Reset isn't helping!

Last night my phone wanted to update to 4.4.4 because it's been wanting to for a while, but I know it wouldn't work because my phone is rooted. It had tried this at least 3 times before and everything was fine; download update, tries to install, fails, boots right back up. I wanted to get rid of the Update notification in the top bar, so I just ran it again thinking it'd be okay. Well, this time it bricked my phone, leaving me at a neverending loop at the boot animation. I first tried to wipe the cache and dalvik cache, which did nothing. Then I tried a factory restore, which also did nothing. Then I reinstalled the stock 4.4.3 rom I had been using, which did nothing. Then I wiped the SD card completely and reinstalled a stock 4.4.4 rom through sideload, which has done nothing. My phone just sits at the boot animation and taunts me. Worse yet, I have a 16-hour drive tomorrow and my phone was going to be the majority of my sanity during that time.
What should I do?? Is there anything I can do? Normally I would just contact Google to get a replacement (I've done this before when the 4.2 update was causing a lot of bricks,I think it was 4.2 anyway, I forgot) but I'd like to have a working phone for my 16 hour trip..... if possible. Any help would be greatly appreciated! Thank you.

Well, I never had heard of any devices that still stuck in the bootanimation after flashing the factory image. There is something really wrong.
Did you already tried flashing a custom rom? Can you boot into recovery?

I had a Vanir 4.4.3 rom on my phone that I tried to flash as well, but for some reason it went right into "Optimizing Apps" after the first boot, something I hadn't seen before. Then it got stuck at "Starting Apps...", then after a restart, it too was stuck at the boot animation.
I can boot into recovery luckily, but that's all I can do. I have CWMR v6.0.3.5. I've tried just about everything I can think of. [edit] I was able to contact Google for some live chat support and am now #2 in the queue. Hopefully they can either help me or get a replacement going. Either way, I'd still love any help you guys can give me, I'd really like to get it fixed rather than waiting for a replacement.

Okay, try this: Wipe everything via recovery and with everything i mean really everything! Cache, dalvik, storage, your whole system. There must be nothing left on your phone. Then flash a rom of your choice. Wipe cache and dalvik afterwards and see if it works

I've done that already, Factory Reset + wipe cache + wipe dalvik cache + format system/data/cache/sdcard/data/media. The phone was completely bare and that's when I sideloaded the stock 4.4.4 rom (otherwise it's stuck at the Google boot screen). I'll try it again, though.

Okay right now I'm using the Nexus Toolkit to flash the stock 4.4.4 .tgz image directly from google and unroot my phone (checking the option that the phone is Soft-bricked/Bootloop.
....Okay that finished and I'm still stuck at the boot animation and now I don't have CWMR. ****. [EDIT] But I can still boot into a custom recovery through the toolkit, which is good.

Damn, I really am stumped right now. That's really strange. Normally everything should be fine after a factory reset...
I've search several threads with bootloop problems, but none of them have this persistent bootloop. I believe you have damage your storage somehow, so that the system can't read the files and boot up properly. Maybe because of this 4.4.4 OTA update. Man, that's kinda sucks right now...

I forgot something! Did you also flashed the 4.4.4 binaries?
https://developers.google.com/android/nexus/drivers#makoktu84p
I also read somewhere, that the LG Fashtool may help.
Try this out!

Hm, I didn't think I'd need to with the factory image, but I'll try that. I tried the 4.4.3 factory image as well but that didn't work either. I also can't find anything about the LG Flashtool that's Nexus 4 specific, but I'll try to look more into it.

Wait, how do I flash the binaries since they're .tgz files?

This is really strange man. Flashing stock ROM is the last resort but even that seems to be failing for you.
Have you tried downloading the stockRom again (just to make sure it isn't corrupted). Also, maybe you can try using TWRP instead of CWM this time.
Good luck.

No need to flash them, since you are on a factory image, sry.

Woah now, I've made progress! Maybe.... Anyway, in TWRP, I "fixed permissions" and mounted "system" but now I'm at the "Android is Upgrading, Optimizing Apps - Starting Apps" screen again (it only had to optimize 23 apps?). I was at this issue before when I was flashing roms last night trying to fix it, but going back to here is better than not getting it to boot at all. What else should I try next?
Note: I'm on the 4.4.4 factory image now and TWRP is just temporary through the Nexus Root Toolkit.

And? Did it boot up or just stuck in 'optimizing apps'? I would suggest to try another android version, like 4.3 or 4.4.2 at least.

What about custom ROM? Cyanogenmod maybe? Make sure to downlaod the M7-Release.

Hm, alright, I'll give that a shot.
On a side note, is there a way to lock the bootloader again while in either recovery or bootloader? I fear that if it's unlocked, I won't get the $250 refund for the replacement.

PLZ HELP!! Nexus 6p keeps booting into TWRP menu

Today and after deciding to simply restart my Nexus 6P, it booted into TWRP menu, I tried to reboot again, but no luck. can someone please help?
is there a way to get off the TWRP menu and boot my phone normally?
Note: The root used to simply work fine for about a month now.

Did you take an update? Rom details? You basically said you stuck a fork in a microwave and it sparked.

Have you tried wiping the caches and/or data? Have you tried reflashing whatever ROM you're using? Have you tried flashing the factory images with fastboot?

I will have to call you out here buddy. If you have indeed tried to flash all factory images, you won't even have TWRP in the first place.
Go to this wonderful guide by the wonderful @Heisenberg, and scroll down to "10. How To Flash The Factory Images (And Return To Stock)". You will find very clear instruction on how to return your phone to its factory stock state. This will most likely get rid of the problems you're facing.

No Root after factory reset

Root just disappeared.
This is not a huge problem but when I go to TWRP to reinstall SuperSU, I can't get to the files so I can't install SuperSU.
I have now a MegaPixel ROM with EX kernel and I want to go back to stock. With no root, kernel and recovery... Just don't know how to.

I tried to reinstall SuperSU but now its stuck on boot animation. How can I fix this?

I don't think you can do a factory reset if you are on a custom Rom. Power down your phone by holding down the power button until the phone shuts down. Go into bootloader mode by pressing power and volume down buttons at the same time. Flash complete factory image from Google site using flash-all.bat command. If you don't know how to do that follow the XDA/Heisenberg guide only to the point where it shows you how to flash. Do not flash all the pieces individually like in the guide. Just use flash-all.bat command like Google suggests.

Use the link I posted above. Read it and follow the return to stock section. Like I mentioned earlier, that's a step by step guide to all things 6P. How to root, how to return to stock and everything in between. It has (or at least links you to) all the tools you need. It's a lot more thorough than I am, quite frankly. Just do your best to follow the return to stock section of the guide and if you run into any issues quote me again and let me know where you're stuck and I'll see if I can help. But you're asking for a step by step on how to recover and I've already provided you with a link with those exact steps. Good luck. Specifically steps 10 or 11 depending on if you want to keep your data intact.

I did all the steps in part 10 with angler 7.1.2
It was bootlooping for 5 minute or so. I turned the phone off (While it was bootlooping) and now when I try to boot I get a "No Command" with a opened Android screen. What should I do now?
Maybe I can still flash TWRP and do stuff there?

The no command screen with an Android on its back is stock recovery. When you see that, hold volume up and while holding volume up, press the power button. That'll get you inside stock recovery. From there you can factory reset. This will likely wipe your internal storage. I'm not exactly sure on that, but assume it does. If that's not an issue, do it and try booting again, but wait longer this time. Leave in on the charger and wait 10 minutes or so. If it still won't boot, try again with 7.1.1 factory images. Also if you're using the flash all .bat file try manually flashing each partition using fastboot.
Edit: If you didn't already, don't lock the bootloader. You won't be able to use fastboot or flash TWRP (if that's what you want to do) with it locked.

Sounds like it. That's not good, it sounds​ like a real issue here. How did this end up happening in the first place? You factory reset from TWRP and all this happened? That should have not made you boot loop. You should have been fine and booted and had to sign in again, etc.
Did you lock the bootloader?

I hope it's not a big issue cause I just paid 150$ to fix the screen. I just wanted to give it to my mom fresh (with no root, custom ROM etc...)

Yeah if you're not on stock, don't factory reset from the system. Use TWRP. Try to fastboot flash TWRP back on the phone and see if you can boot to that.

TWRP works! OK that's a good sign (I think so...)
I wiped EVERYTHING (Dalvik/ART cache, cache, system, Data and internal storage)
I will probably try to flash stock now.
