I don't know what the hell happened, but today I went to switch my sim card from another phone to my N4 (I have multiple and like to use different phones every now and then). So I turned the N4 off and put the sim card in it and rebooted it. When it rebooted and got to the lock screen, I could do nothing that didn't involve the power key or the volume rocker. So I rebooted and it happened again! Okay. Reboot one more time. Same thing. So this time I booted into recovery and cleared cache/dalvik cache and rebooted. After a few seconds the touch screen started working again (might be related to clearing cache/dalvik, might not).
No idea what went wrong, but is this more likely to be a kernel issue or a ROM issue? Or something else? I've been running this rom/kernel since 3/02 and it's been flawless until now. Has anyone else had this happen?

It has happened to me before. I would definitely update both as there might have been a bug fix on that specific ROM/kernel type. I would probably think it would be a ROM issue, but I guess there's a chance for the kernel. I would wipe and update and see what happens.

TL;DR: I have flashed the stock 4.2.1 image through fastboot, and yet my n7 wifi still reboots continuously at the google screen with the little unlocked lock.
Background: I have had the device for about 3 months, no real problems with it before this. I was reading yesterday night and i fell asleep, and thus instead of being on my desk all night the device was under a blanket. When i woke up, I opened the cover and found it on the google screen with the lock. It was warm, but not incredibly so. I thought it was weird that it had rebooted and apparently frozen, but i held down the power to turn it off. when i turned it back on, it started the google screen, then went black, then started the google screen again. Seems like there may be some sort of a kernel issue that is keeping it from booting. The next thing i did was to go into recovery (had CWM at this point, and it was rooted as well but that's a moot point if i can't get into the system.) and i did a backup, then wiped data and did a restore from the backup that i had just made. after rebooting, it made it all the way into the system, and seemed ok. I set it down, and a few moments later it turned off and started doing the loopy google screen thing again. Next, I went into recovery and wiped data/factory reset, and tried to boot up. no luck, still looping. Next, i grabbed the 4.0 toolkit from the dev section and tried to flash the stock recovery from that, but it was proving troublesome so i just downloaded the image myself and fastbooted then replaced cwm with the stock recovery, wiped everything, and flashed the 4.2.1 image. that should have worked, from what i understand, but no, still being loopy. I re-wiped and flashed, tried 4.1.2 instead, that didn't work, and i re-did 4.2.1. after flashing 4.2.1 and then leaving it boot looping for a little while, i noticed that it sometimes made it into the boot animation and then the animation froze and it rebooted and looped more. after a few more tries, powering it off, leaving it for a few min, and powering it on again, it booted all the way to the welcome screen to pick a language and then froze. some number of loops later, it made it all the way to picking a wifi network and froze. I have yet to make it past that point. Thinking it may help, i fastbooted CWM onto the device, so i have a more capable recovery now. I am now going to look into pushing a non stock rom to the device to see if that will help at all.
Any ideas on what on earth could have caused this? Was it just that the device was a little warmer than usual for a while?
Any ideas on how i can fix this? Much appreciated!
Lastly, should i consider looking at sending it back to google? I didn't think there was anything wrong with the hardware, but i'm not sure.
Thanks!
Update: After leaving the system repeating it's loopy boot thing for about 45 min, it seems to have finally booted into the system, and has yet to reboot again. I have no idea why this happened in the first case, nor why this finally worked in the end, but so far it seems ok.
More: Ok, so it still seems to be looping a lot. I have no idea why still. I'm having trouble getting it to boot back into the system, so hopefully something helps fix this.
Ok, so a day later it seems to have settled down such that there's very little looping on the google logo screen any more; now it just tends to randomly reboot when in use. this is quite frustrating, but seems more similar to what others have reported to be the case with 4.2.1. oddly, i never had these reboot issues before it decided to fail the first time, so i'm not sure if this is just because ii'm on 4.2.1. I may look at flashing back to 4.1.2 and staying there, i suppose it can't hurt. does anyone else have any ideas as to what could be going on?
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
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!
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..
Sent from my SM-G935F using XDA-Developers Legacy app
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.
I installed 8.1 last week. Everything was working smoothly. Was trying magisk youtube mod. Screwed something up. Phone went into bootloops. Reinstalled everything .Wiped data. Now my phone reboots randomly. Everything stock .Rooted with Magisk. Mainly it happens whenever i launch a new app(An app which was not launched before). After few tries, the app opens up and doesnt' result in reboot.
Any ideas what could it be ?
You should of wiped system and cache also might be your problem. Also if you where using any substratum themes remove then manually as well. Not sure if they would cause reboots.

FC's are one thing but random reboots are a completely different animal. I would completely wipe the phone and apply the latest factory image using flash-all.bat. If that doesn't fix it you may have a hardware issue (eg. degraded battery).
Wiping caches helped
I'm running SUPERXE-8.1.0-OPP5.005_v1.5.1.
My 6P was going crazy, restarting every 5 minutes or so. It rebooted so quickly it felt like a soft restart, so I thought powering off and rebooting to recovery using the power + down volume to clear the cache in TWRP would help.
Cleared system and Dalvik and powered down. Full reboot and (for now) it feels much happier and hasn't spontaneously restarted yet. That was about 15 hours ago.
Hope I didn't just Jynx myself, but I think it helped...
I've flashed the final 8.1 images to upgrade my 8.0 unmodified system. Now I've random reboots, usually when I've leave home to go to work or vice versa. Something related to wifi, that I'm connecto on both my work and home?
Same here I had to factory reset I'm having a feeling it's going to happen again. I am on factory, rooted with magisk. I always use SuperSU not saying that is what it is however it did happen when I got home from work and just kept rebooting before I could unlock.
