Random Shutdowns - Nexus 6P Q&A, Help & Troubleshooting

hey everyone, currently running N dev4. but ever since i got the phone, even when i had stock marshmallow, it shut downs randomlly every now and then, i never saw it happen but i just see my phone turned off after picking it up. the phone runs great and i kept it in very good shape, it doesnt have a scratch..anyone else?

The first thing I would try is a factory reset or a full wipe of the device by formatting system, cache, dalvik then reflashing the partition images/rom and see if the problem persists. If it does, you may want to return for warranty

Got stuck in an endless reboot on a non journaled rom.. No problem!

I tried restoring the stock battery icon using ACS 1.1 and my phone got stuck in an endless reboot cycle. I kind of started freaking out as my phone had been acting flawlessly prior to this and I was scared of corrupting my data. I had a recent restore point saved (I have MyBackup make one every morning while I'm sleeping) but that would mean I'd have to wipe my phone and after everyone complaining about how hard it is for them getting ACS 1.1 to work on there phone I was scared to test my luck a second time. I thought the only other option would be a battery pull which would lead to bad data with bad backups. So instead of following one of those two options I three finger rebooted out of the loop and immediately three finger booted into CWM. I wiped only my cache and dalvik and then reflashed 1.1 over the existing one. I then rebooted and the only things I had to do were reflash my Vision kernel and delete a few apps that I did not want that come with the ACS rom that got reinstalled. I assume none of my data got corrupted and I know this probably won't save everybody from corrupted data due to endless reboots but just thought I'd share my method. So far everything has been running just as good as ever.

p3113 random, unresponsive, locking up

hi not sure if this is just me or others have same problem i have had my tab since june 2013 i have rooted cwm twr and flashed many different
roms.
lately the tab is locking up and being unresponsive when doing the simplest of things even on boot with the boot logo it lockup
does this also when running any rom i have tried about 6 or 7 of the best roms all with the same results..
i have wipe the whole device meaning i have formatted /system /data /internal sdcard
has any one else had this problem and was you able to fix this unresponsiveness, locking up
im thinking of reflashing stock update from nov 2013 and seeing if this maybe resets what ever it thinks is wrong
is there some thing else im able to do
then re-rooting and re-flashing my costume rom
i would like to avoid all of that and see if any one has a faster fix then that
i came across this posting which seems like just what i have locking up
seems there was no fix as well

I've see this before, try to flash the tablet again and wipe all data including the cache (most important). I used to see flickering on my galaxy tab 8.9 and weird unresponsiveness, usually cache wipe is enough. Most people with those problem didn't wipe the cache before a new flash.

[Q] TMo Note 3 Deciding Rebooting is the Only Solution

Ended up "solving" this by doing a stock restore via Odin, after which TouchWiz would never load an icon (crash loop). Reinstalled TWRP via Odin, then flashed ViSiON X N3 via TWRP.

Morning guys,
I've had some reboots lately and a weird situation last week where I had to do operating system surgery to get the thing to boot at all.... HOWEVER things were going quite well for some time, and it's been rooted and non-stock for months.
Nevertheless I woke up this morning and it was off, I figured the battery had died so I swapped batteries... It boots, it gets to the launcher and it loads the app icons then freezes and reboots... over and over again.
edit: to be clear, as soon as the slider bar touches the right-hand side the phone freezes, the vibration holds for several seconds, and then the device reboots. obviously not what one expects from this operation (having done it before). I was able to wipe the Cache separately... trying to wipe the Dalvik cache all by itself in an advanced wipe does this reboot thing.
OK I said, i will just clear and reflash this.
Going into TWRP, attempting to do a factory reset wipe just freezes, buzzes, and reboots immediately (to the not working OS)... in order to make this all stop I pull the battery, because now the button on the side won't seem to do a hardware poweroff for anything. Just ends up resetting the current reboot.

Any advice would be helpful now. I was just going to say forget it and grab the tiniest ROM i could find and ride it out until I upgrade the device, but now I'm just concerned with getting it active. The rebooting in recovery when trying to do a wipe does not make me feel too great. First and only problem I've had with android roms.
Thanks,
Chris

Freezing and rebooting

Classic "my phone keeps freezing and rebooting". I am quite in the know about flashing roms and such.
It started on the stock firmware 6.1.1 (i think it was). I dd factory resets, cache wipes the lot. It would still randomly reboot.
So i flashed Telstra version of 7.0. Still froze every now and then. Did the same things as above.
Flashed TWRP and wiped everything, flashed Renovate Rom and the bootloader for it, Still did it. Numerus factory resets and wipes of everything. It would freeze at any point from startup, to having setup the phone and making phone calls or on facebook or whatever. It would even freeze in twrp, or loading twrp.
I found that the data partition was corrupt so i re partitioned to ext4. Still nothing. I reformatted every partition so the phone was a complete brick with nothing on it and after flashing clean again it would still do it.
Whats the issue that I'm missing, or is there a way to log so i can find where it keeps getting stuck? It gets hot and blue light flashes and i have to hard reset it or sometimes i have to let the battery drain so i can turn it back on again.
pls help?
Hmm i will give you an advice so you dont have to wait for your battery to drain...just press volume down and power button for like 5 secs and phone will force boot. Anyway back to your problem...did you tried flashing latest stock samsung firmware?

This advice doesn't work with my phone even with holding the buttons for 30 secs and more. For rebooting I can only wait until the battery is completely drained. With little hope for another way shortening time to the next reboot any help is appreciated.
Same here...experiencing the same prob...
Same problem.

Sounds like you need your motherboard replaced i had the same issues on marshmallow thought the nougat update would fix it but realized it was a hardware fault not software..left it in store to get fixed and on repair sheet it said faulty motherboard..

As i know some S7 have motherboard hardware problem, mine has too, what help? warranty and they replaced motherboard. But if you root, you can say good bye to warranty, they look at knox first with this problem.

Touch screen not working - fixed twice after multiple factory data resets

Hello. I have a recurring issue with a 6P I bought for my daughter. Twice her screen has stopped responding to taps or presses. The problem persists even after a factory reset. The first time, I fixed it by wiping the cache partition in stock recovery after the factory reset (I know, makes no sense, since the cache partition gets wiped during a factory reset). The second time it happened, I had to factory reset and wipe the cache independently 2-3 times, and luckily it started working again. I'm not sure whether the resets or wiping the cache did anything, or if just restarting the phone multiple times is what fixed it. Either way, I don't want to buy another phone for her if I can figure out what's happening with this one.
Her phone is a Google Nexus 6P, stock everything. Unrooted & locked.
Note: After happening the first time, and finally getting it to respond, I set her phone up from a cloud backup. This time, I set it up as new. I really don't see how it would matter, as the problem persisted after a reset, before setting up the phone again. I guess I'm leaning on multiple reboots solving the problem, but just don't know.
Any help would be greatly appreciated! Thanks!
