Weird frustrating problem - Nexus 6P Q&A, Help & Troubleshooting

I'm currently running the latest PureNexus (MM) with a pretty vanilla setup, I.e. no xposed, root, etc. All the sudden yesterday I had a hard crash while doing nothing in particular, a sudden reboot that sent me into a boot loop. It reboots right before the boot animation would appear. The only way I was able to fix it was to wipe the data partition. I was subsequently able to restore my backup and it booted successfully. The frustrating part is it's happened several times since then. In fact I can't keep it running more than a few hours without the same thing happening, even after doing a full wipe. Any ideas?
Thanks!

Arg, I tried flashing the new Android N system image (the official one) which basically flashes every partition and I'm still getting a boot loop. Is it possible that my SD card went bad?

Did you use flash-all.bat from google image or you flashed the images one by one?

I tried both. Both N and MM. Apparently I stumped Google too, they're sending me a new one.

that's weird... Glad you got a replacement though!

[ROGERS SGH-1337M] Wont Reboot Without FULL WIPE

INFO: I rooted my device last night and installed TWRP using GooManger. I tried tested two different Roms. The first one was Google Edition 4.2.2 - v1.3 & the second was GoldenEye. Both Roms Seem to function properly. My Device is SGH-1337M ROGERS
PROBLEM: When i reset my device, even after a clean install, my device gets stuck during boot. I've tried going into recovery and restoring backups from this point and they all fail. The only possible way to get out of this boot freeze is to Wipe entire internal storage. At that point, the phone will reboot. This does not appear to be a boot loop as It just shows "Samsung Galaxy S4" and won't budge (seems frozen). I have no idea what the issue is but i suspect it may have something to do with the kernels provided with the Roms? Any help would be much appreciated!

Which ROMs are you installing? On I337M your best bet is T-Mobile ROMs and Kernels. I have Bell I337M and have no issues.

Are you wiping with TWRP? I heard there are issues with using it to wipe and restore or loading a new rom after wipe. Just restore using Odin and then load a new rom (or restore a backup) without wiping. See if that solves your problem of bootlooping

i just went through this all last night what a pita , problem is twrp , if you do a full wipe when you type the word yes , you can only bootup 1 time then it gets stuck next time you boot , theres no way to fix it , even going back to old version of twrp wont do it , you have to compleatlly remove root and return to stock , re root and install twrp again , then if your luck your nandropid backup will work , it took me 5 hrs to fuger this all out , stupid twrp drove me nuts .,...
in short , return to stock and reroot , then never do a full wipe where you have to type yes

[Q] Stuck on Samsung boot logo when rebooting from different roms

Having an issue that I cant seem to figure out. I have been using various roms eg Omega V7,S4 Google Edition V16, Fox Hound 1.1 etc. They all install fine, factory reset before and after wiping the various cashes as required. I also format the SD storage to be sure, but once up and running, apps installed, every time I restart the phone or for some reason it freezes it just get stuck at the white Samsung S4 logo.
If i go back in to recovery (TWRP 2.6.0.0) factory reset does nothing to fix this. I have also noticed that sometimes the internal SD shows as 0 Mb, and I have to reformat this to re-install a ROM. (Getting corrupt some how?) Only re-installing the ROM from fresh seems to get my phone up and running again. Until something happens. Any ideas?
I follow all instructions as detailed, and never come across this issue with my S3.
Ok after trying a few things the only thing that seemed to fix the problem was reflashing stock firmware using oden.
I had to reformat the internal storage again as this was acting like it was encrypted, which it was not. Think this problem that caused my phone not to boot when when restarted.
No Idea why it did this but its fixed now.

[Q] Phone bricked after battery replacement.

The last few days I had an experience that I want to share. Maybe it helps somebody else.
Last week I upgraded my Defy from Quarx's CM10.2 to CM11 version 20140724.
It ran for about two days. It was stable and the performance looked better than before.
Then, when I was outside, my battery was empty. I always have another battery with me, so I exchanged the battery.
Then, two seconds after I inserted the battery, a black screen with the following white text appeared spontaneously, without pressing a button:
Bootloader
09.10
Code Corrupt
Ready to Program
connect USB
I could not enter recovery, or anything else.
So, I decided to go back and flash the original Motorola Android 2.2 version.
On earlier occasions this worked perfectly when I bricked my phone, but this time, after flashing the SBF with RSDlite, the phone hang while booting with the android logo on the screen. Only after a few hours of trying different SBF systems, the idea popped up, that the problem was not in the SBF, but in the combination of the old Motorola system and the new CM11 data partition. So, I entered recovery and wiped the data partition.
Then the system booted normally and I could proceed with rooting the system, installing custom recovery and restoring the backup.
Everything is back to normal again.
Now, I wonder what could have caused this problem.
I am a bit suspicious about the backup method I used. I create backups with the online nandroid app. The CM11 system installed the TWRP 2.7 recovery. The first time I tried to restore a backup, I noticed that the TWRP recovery had a problem with the old (CM10) and the new (CM11) backups, because they contained files for partitions and-sec and recovery, that it could not handle. In later attempts to restore the backup I unticked these partitions and the restore seemed to work well. I rebooted it several times. Could it be that these attempts damaged the system in such a way, that only when inserting a battery, the corruption was detected?
Or should I assume that there was a hardware glitch when the battery was replaced?

iirc this was one of the bugs of cm11. if you let the battery runs completely down, it may not boot again. not sure if this has been fixed with the latest cm11.

Massive softbrick (haven't found a solution yet)

Hello everyone,
So here's my story: I got a 6P short after release and it's been amazing. After switching from a S6 I couldn't be happier until 3 days ago.
I was playing around with my phone (checking for updates on the play store if I recall correctly) and I was going to switch from 4g to wifi. I went ahead and pulled down my notification shade and went to press WiFi but misclicked and hit Hotspot which was below it. My phone suddenly froze big time and this is for the first time ever since purchase.
At first I thought I'd wait it out since the device was completely unresponsive, home button didn't work and neither did anything on screen. Buttons didn't make a difference either. 10 minutes went by and I ended up force restarting by holding down power + volume up. First part of my bootup went fine but when it got to the android boot animation after I put in my pin to allow the device to start it dropped from the smooth usual framerate down to 1 frame every 10-15 seconds and it slowed down further until it came to a complete halt around the time the android letters appear.
My first thought was corrupt rom so I went ahead and wiped data from the stock recovery. I was running completely stock with no modifications whatsoever. That didn't do anything. Phone still froze in the same boot phase. Desperate I unlocked bootloader to flash a clean fresh image to try to fix it and to my surprise that didn't change a thing.
As I was getting pretty desperate already I had one more idea and that was to flash up to the Dev preview. To my huge surprise it booted and I jumped from excitement. So I started setting up my phone again. I got past the prompt to insert sim card and I was now at the screen to choose a wifi network. As soon as I clicked into that the phone froze up again and at that point I lost all hope.
I wiped data in stock recovery and shut the phone down for the night. On day 3, today I woke up and tried starting the phone and it worked as if nothing had happened. I went through the setup and set up my phone on the N preview. At a certain point I was planning to go back to the latest official build but for now I was happy my phone was back from the dead. Later today I tried to restart my phone to clear all running apps etc and it froze up on boot.
I'm losing all hope that I'll be resolving this myself so I'm reaching out to the community to see if anyone's had this happen to them before and hopefuly for a solution. It's still under warranty so I can eventually send it back to the retailer but I'd rather not have a phone for 3 weeks.
Any and all help is appreciated.
Thank you for reading through my long and probably pretty boring story!
Have you tried flashing the factory image? If yes, did you made sure to wipe/erase the system, boot, vendor, and cache partition before flash the corresponding img files?
To the OP, is there any reason you did not flash to release version 6 instead of Dev preview ?
Also, any reason you can not simply do the "unenroll" from https://www.google.com/android/beta ?
It will require you to setup certain settings again as you will be back to a "factory reset".

DJBhardwaj, i haven't specifically erased those partitions. I was under the impression wipe userdata along with reflashing did that. I will try that tonight when I get home!
Xdafly, I only updated up to N as a last resort because at first I had a locked BL. I was planning to unenrol but that would've been too late as it self bricked after a restart.

Well I just did the erase thingy and my phone booted but wifi won't turn on. Enabling hotspot doesn't brick anymore but I now suspect WiFi might've been the issue. Any tips on how to find out what it could be and possibly fix it?
Edit: 2 restarts and a factory reset later I'm back to bricked same way as before.
try safe mode

That was my first thought, that was the restart that bricked it again. Safe mode shouldn't have made a difference since I hadn't even logged into Google account for apps.
After reading the very first post; sounds like bad WiFi hardware.
All the hanging has been related to WiFi or Hotspot.
I think you should get a replacement

Is your phone rooted and did you install Xposed?
Over the weekend I shutdown my 6p (stock rooted with April security patch, Xposed v80) and charged it. When it turned it back up I kept getting "Unfortunately, nfc service has stopped". Long story short: I ended up factory reset my phone and reinstalled EVERYTHING and I still got into bootloop. Then I came across
https://github.com/rovo89/Xposed/issues/113
https://github.com/rovo89/android_art/issues/28
At the end of the second post rovo89 (developer of Xposed) fixed the bug in V83. I wiped my 6p once more and installed everything with v83. Problem solved.
Good luck!

Nexus 6p not booting (running custom ROM)

A little bit of background.
Prior to this problem I was running dirty unicorns and elementalx kernel. Given that lately I had some freezing issues I decided that iro was time to update my ROM. Being the first time that I manually update a ROM and not having found anything online I thought (dumb decision) that all I had to do was to flash the most recent version. After I did that the phone did an app optimization (idk if that's how it's called, basically it optimised all the apps for the new version of the ROM) . After that the phone wasn't booting up, the dirty unicorns loading screen was running for half an hour and nothing happened so I restated the phone. When it asked for my sequence a message popped up "it looks like your vendor image is obsolete". The phone still wasn't booting up so I decided to restart once again and install the latest vendor image. After that the phone wasn't booting up so I decided to do a backup with twrp (version 3.0.0.0) and do a factory reset.
Plot twist the twrp decryption sequence (that worked 10 minutes before) now wasn't working so I had no way to access any of the phone's files.
Basically the phone won't turn on and I have no way of accessing it's files
I'd try a factory reset but there are some photos and whatsapp messages that are important to me and I'd rather not lose them.
Any tips?
Apologies for my terrible English

The best thing to do is this guide. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page384. Just go full stock without formating the internal. Flash twrp and see if you can get your photos. Next time back your photos up with Google photos if available in your area. Good luck

To update a ROM all you usually need to do is flash the newer version, but you also need to flash the newer vendor.img of the updated ROM is based on a newer Google build. Failure to do this is what caused the "it looks like your vendor image is obsolete" message to appear. I'm guessing you know this though as you went on to flash it later.
Not sure what happened with TWRP but you've done something else wrong at some point. Best idea (as pointed out above) is to flash the factory images. You can try it without formatting userdata in order to retrieve whatever it is that's important on your storage, but once you've retrieved whatever you need (if you even can) you'll need to format it because you really need to start fresh.
