Hi,
I am writing this on behalf of my mother's phone. She has a completely stock Nexus 4 on Net10.
This phone hasn't been touched by a computer. Any development settings are also disabled.
I came home from work and my mom showed me that her phone wouldn't boot. It was boot looping on the "X" boot animation.
So I went ahead and accessed the boot menu and selected recovery and did a cache wipe. No help. I let the phone run out of battery and charged it back up, no help.
I have no clue what happened. The phone was working fine previously. Again, the phone has NOT been unlocked, rooted, etc. Completely stock Nexus 4.
I would like to fix her phone but I would also like to keep her data intact. She even told me it is very important to "keep everything on the phone".
Any assistance would be great.

Try the following:
- wipe cache and dalvik cache
- Flash a custom kernel
- See if boots
- Make a complete UROOTED backup and save it in the computer
- Flash factory image and relock bootloader
- Restore backup
Tell us if worked
By flashing a custom kernel it is required to unlock the bootloader which will wipe the entire phone.
Your only hope is to use stock recovery to install a signed OTA package (if it's on 4.3 wait for 4.4 ota package).

So, I have read a lot about TWRP sometimes bugging out and randomly encrypting phones and adding a password to which the user either never set it up or that TWRP doesn't accept it. This has recently happened to me and I cannot use my phone and I don't know what to do.
I have had the bootloader of my phone unlocked since day 1 when I bought my phone (release date last year) and have been running PA ever since. I have never had any problems with it, until about 5 days ago, when I grabbed my phone and everything started crashing and the camera was apparently not available. I didn't know what was the deal with it, so I rebooted the phone and it entered a bootloop (it hangs on the Google logo for about 5 minutes and then it hangs on the PA logo screen forever). I went on to the bootloader and started TWRP to see what was the deal. I originally wanted to grab certain files off the phone in case I had to do a system format, but when I got to TWRP, it asked me for a password which I have never set up and I tried every combination I could think of but it always failed. Everything was encrypted and without the password I couldn't get to it. I tried wiping everything including a factory reset before resorting to a system format (which I read about it and apparently is meant to be the solution). Everything failed because it couldn't access the /cache, /data, nothing. I went on to do a system format and although that is meant to wipe the phone and remove encryptions, it also failed to wipe the /cache and although TWRP says that the wipe is successful, the phone is still encrypted, the password is still around and it bootloops. I have tried the system format like 50 times and always the same.
Can anyone help me out with this? I am currently travelling around but am at a hostel where there is great internet and pcs, so I can install drivers, toolkits and such. I actually started looking around for new phones, since I cannot for the life of me get the phone to start again.
Note: The phone was working perfectly fine, I put it down to have dinner and once I finished, I tried to use it and it started to bug out. I also read around about this, and everyone's issue gets fixed after a system format.
Any help, would be greatly appreciated, that phone is the only net device I have on this trip and it sucks to not have any way to contact anyone.
Thanks.

Don't blame TWRP for something it doesn't do.
Looks like your device have an EMMC failure, sorry.
You can try installing factory image, or last resort restoring by download mode, but I think the flash memory in your phone is gone.

I didn't mean to blame TWRP. It is just that it was when I am on it that I get asked for the password and I was under the impression that it was TWRP that did the encrypting (I am in no way a developer or even very knowledgeable when it comes to the under the hood stuff, I usually only follow the tutorials). But thanks for the reply and the link, I will try that and hopefully get the phone back working.
Also, I did read in a thread that apparently this can occur due to hardware failure, I was just hoping this wasn't the case.
This happened to me on an old phone. Not sure why. Factory image fixed it. Could be a different issue but its worth a shot.

Did it suddenly happen or did you change ROMs?
I tried a new rom for the first time and then went back to wicked 9.1, I'm thinking that triggered something.
I think I got a fix though, look here: http://forum.xda-developers.com/showthread.php?t=2588377

Around a week ago everything was force closing on my N4 so I decided to reboot it, when I did it got stuck in boot loops. Because of this I went to wipe the data and cache so I could flash a Rom but when I did all my data from my SD partition had disappeared. This has happened to me before and the way I solved it last time was to unroot and flash back to stock using the Nexus 4 toolkit. However when I went to do that this time it said my boot loader was locked so I couldn't complete the task. So then I unlocked the bootloader which apparently is successful but when I refresh the bootloader it seems to be locked again. Over the last week I have tried sideloading zips, force flashing, unrooting, unlocking the bootloader and all this on both a mac and windows toolkit.
When researching this problem I only could find one thread which resembled my problem on xda however it was about the Nexus 7 and the person ended up sending it back to Asus. Would be great if someone good respond, thanks!
(Also my device is a Rooted UK 16gb if that helps)
It sounds like your emmc flash memory is bad. Not being able to lock or unlock the bootloader is a sign of that. You should warranty the device.
I agree. I faced a similar problem on my Optimus 2X. It started with occasional bootloops, and last week it got to the point where it was boot-looping after every boot w/ force closes, missing data, and e2fsck did nothing, because the fixed errors came back within hours. Definitely sounds like your memory chip has called it quits.
Last week I was minding my own business, doing usual stuff on my phone and the device spontaneously rebooted into a bootloop at the Google logo. So I think "OK, no problem... I can try wiping cache/dalvik or at worst I have a recent nandroid backup" and proceed to reboot into recovery... except that it still hangs on the Google logo. Stuck at work I did a bunch of googling and found one other user who had the same thing happen recently.
When I got home I tried to fastboot flash TWRP again... but alas was still stuck at the Google logo. Next was a full flash of Google stock images, but that did nothing either... so I relocked the bootloader and had my provider (TELUS) send it in for warranty repair. I just had it returned with the repair stating the main board was replaced.
I have noticed a few users posting about being stuck on the Google logo and this concerns me a bit, as it almost seems like there may be some inherent hardware flaw causing the issue.
So I'm throwing the questions out there: Has anyone else had similar problems and is this something we should start to be concerned with?
You're not alone buddy. I'm in the same boat. Have sent mine for repair yesterday.
Thats discouraging news. How long have you guys owned the phone? Did you buy it new?
I love my 6p but if enough of these units are defective they should probably be recalled. Hard to gauge if its an anomaly or a serious issue. Hope for the former...
I think I may have the same problem. My phone wont boot past the logo at all. IDK what to do at all.
I have the same problem, stuck on the google logo, I already wiped the cache partition and nothing, did a factory reset and nothing, what else can I do??

Check if you can boot twrp. If you're not successful send the phone for repair. No option available to recover from this king of hard brick yet.
Weird thing is anything and everything is doable in fastboot. Moment you try to boot OS or recovery, gets stuck indefinitely in Google logo and reboot.

this exact thing literally just happened to me on Thursday. I was fully stock never unlocked the bootloader or anything. phone suddenly started looping, tried wiping cache, doing factory reset, finally went nuclear and unlocked the bootloader and flashed system images. nothing worked. warranty replacement is enroute.
I bought it on release day.
Old issue with Nexus devices. Has been going on since Nexus 5

I got the phone new from TELUS at the end of December, so about 6mo before I had the issue... Thankfully fastboot still worked so I could return to stock and relock the bootloader before warranty claim...
Starting to wish I had done the insurance option if these things are failing after 6mo and I'm on a 2yr contract

Did they give a new/refurb or was it they changed motherboard/memory chip?

Was my original exterior, the dings were still on the corners so it was just motherboard replacement

I'm also having this issue, but I get stuck at the boot animation instead.
I have Nexus 6P, Stock Android 6.0.1 July, SuperSu v2.74, franco kernel r23, Xposed v85. Everything was running fine when suddenly the phone rebooted and got stuck in boot. I reboot into recovery, deleted the /data/data/de.robv.android.xposed.installer/conf/modules.xml, flashed xposed unistaller zip, cleared cache and rebooted. Still stuck in boot. I reboot into bootloader, flash boot, system, vendor image of July factory image and reboot. Still get stuck at boot. This is happening for the third time to me. Happened in May, in June and now in July. Only thing that works is restoring a nandroid and then again flashing the latest factory image. But that way, I lose days / weeks of data, depending on when that last nandroid was created.
That really sucks, but doesn't sound like a hardware failure from my understanding... I lost ALL my data when I had to send it in, since my failure resulted in no access to the internal memory... Lost a few pictures which was a real bummer, but lesson learned and now I'll be backing up my memory more frequently and also setting up cloud backup for photos

It's likely a software failure. When you flash via fastboot, do you reboot back to bootloader after flashing radio and bootloader? If not then that's likely what's causing the fast boot method to fail for you. The first time after I did a complete fastboot flash of the software I fell asleep and woke up in the morning to my 6p still at the boot screen. When I re-traced my steps I found out that my mistake was not properly rebooting after flashing radio image, then doing another reboot after flashing bootloader.
Got my device back. Same exterior. Was told that motherboard was changed. I could notice that from fastboot.
eMMC changed from Samsung to Toshiba
DRAM changed from Hynix to Samsung.
My device joins this list. Gonna send it for repair tomorrow and hoping it is covered under warranty.
Additional update. I know I missed the bigger scheme that changed. My IMEI.
Just curious what happens if I restore my previous efs partition backup after backing up current.

my phone randomly locked up, then rebooted today. But when it rebooted it was stuck with the white google logo flashing. I can get into the bootloader mode, but from there, choosing recovery or anything else gets back into the white google bootloop. I called service and they're sending me a replacement. Phone was stock with a locked bootloader.
Today I was browsing the internet on my Nexus 6p when it suddenly cut to a black screen. When I tried to restart it, I noticed that it was stuck in a bootloop. After some searching, I've tried to wipe the cache, delete the data, do a factory reset etc. I did root my nexus approximately 3-4 months ago, however I went back and flashed the stock factory ROM. I've been trying to flash a new ROM now, but my PC isn't detecting my 6p as a device. I've looked at the device manager menu, and I'm seeing nothing. After some looking around, I've seen that some 6p owners are experiencing bootloop problems. Any idea what I could do?
Ps. I bought my phone via a carrier, freedom mobile.
Note: I WAS NOT USING A CUSTOM ROM, I HAD FLASHED A FACTORY IMAGE A FEW MONTHS AGO
Do you have TWRP flashed? Can you get the PC to detect when in TWRP should work as soon as you get into twrps menus.

I have managed to get TWRP installed, and now my PC is detecting my phone. I managed to get it to work again, however after around 15 minutes of use, it decided to freeze, crash, and go back into a bootloop.
(I managed to fix it by flashing an OTA update, I'm not sure if the TWRP installation helped)
Wish there was a way to test memory if it was a PC I'd say memory or storage was bad.
