Rooting a Factory flashed image?

I tried to go from my AOKP device to a stock rooted rom I downloaded from the Development Section here, but it seemed to go horribly wrong.
I got force closes all over the shop, so I did a Factory Reset and tried again, still got Force Closes.
I tried to restore my Backup, but it seems that 4.2 puts my SDCARD data in a folder called /0/, so TWRP couldn't find them.
I have ended up downloading the Factory Image for 4.2 from Google and have decided to start from scratch. (And deleted ALL MY DATA in the process!!)
So, is there anyway I can root this stock ROM? I have just re-installed TWRP, so I am set with a custom recovery!

This worked for me.
It might cause a boot loop.. Don't worry about it, let it sit a few..then power off
And restart.(see the last page in the thread.)

[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.

[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?

I also read somewhere, that the LG Fashtool may help.

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.

Nexus 6p weird bootlooping.

Hello xda community!
I received the nexus 6p christmas and after a few hours playing with it, I unlocked, installed twrp and installed cm13. I then installed ak kernal. My phone installs both fine and runs as normal without any FC. Then this is where it gets weird. When I had my new rom and kernal all set up. I go into TWRP and create a backup. I restart and I'm bootlooping. It tells me my device is corrupt. It did this with the original backup of stock rom, cm13, with and without ak kernal installed... and then sometimes my phone will soft-brick (gets stuxk on google logo) I really love cm engine as I habe a theme. But I'm unsure what is happening to my phone.
Any help is appreciated! - thanks.

The bootloader message won't go away until you lock the bootloader. Its just there as a warning to you in case you did not unlock your phone. As for CM I'm sure there are still many bugs to be worked out. I know I'm going to wait before Flashing it until I see people enjoying it as a daily driver. There are some great devs here in the n6p forums though so I recommend checking out some other ROMs too.

No it isn't necessary to wipe the userdata partition. No modifications are stored in the userdata partition. It would only be necessary to wipe system, data, cache, and dalvik cache. And probably flash the vendor partition too. Not userdata though.

I had a similar problem when I botched a SU flash, same warning then it would take forever to boot, then the rom would degrade over the next several minutes. I know its not fun to start over, but it was the only thing that cleared all the problems. I didn't want to take more time finding another solution when going back to stock is so simple with this device. Follow the instructions in step #11 of Heisenberg's guide (great guide, I link it to friends a lot). Then start again, I know, not what you wanted to hear. Hope this helps!
I am also in agreement with Heisenberg in regards to the userdata partition.

Thank you very much for replying. I have found the root of the cause but no solution. Uninstalling or disabling system apps will cause my phone to go into a "optimising apps" boot loop on the next restart. What do you think? ++ every restore I make on twrp either soft bricks or bootloops. Crazy!

I have reinstalled original stock files from google. I've wiped everything numerous times. Installed ROMs just after. It took me a while but I think it comes down to the system apps. I'm running a custom ROM, cm13 and my phone is running fine. I know if I was to delete all the unwanted apps off my phone, on next reboot it will try and optimise apps, finish. Says starting apps... Then reboots. Follows the same process.

Thanks for your reply. I've actually now narrowed itnright down to a few apps, maybe gapps. Sound recorder, voice recorder app and the google app. Either one or more of these cause my optimising apps bootloop.

See the sticky thread in General: https://forum.xda-developers.com/nexus-6p/general/psa-twrp-backups-lockscreen-security-t3245070

You might be better off flashing the full factory image to start over and then reflash whatever you want in terms of recovery and custom rom. I did that when I was in the same situation as you. But I have never successfully restored a nandroid backup on the 6P and I never had that problem with any other phone I have ever owned. Different versions of TWRP only give me different issues when I try to restore a backup. I've had bootloops. I've had TWRP ask for a password even though I removed security before making the back up as people advise. I've had backups that seemed to restore until I started getting error messages that there was something wrong with my device and I should contact the phone manufacturer. I've given up on Nandroid backups on this phone.
