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.

Hi,
I appear to have gotten my phone into a bootloop. Nothing I did should have caused this. It was working perfectly when I went to sleep last night and when I woke up the battery was really hot and it kept restarting. It boots to the lockscreen (note: not a black screen, i can see my homescreen), vibrates a couple times then restarts. I have tried safe mode which does not fix, reflashing my rom, wiping cache/dalvik, booting with simcard and sdcard out... I would love to avoid wiping data if possible (and I'm not even sure if that would help at this point). Is this a hardware issue?
I believe you did all you can possibily do. the last choice is to Odin back to stock. you will have to either stick with the bootloop or lose your data but save your phone. by the way, no one can really help you unless you tell us your phone's firmware version and you have to tell us whether your phone is canadian or ATT or whatever...
Hi,
I have a SMN910F rooted on stock kitkat downloaded from sammobiles, also having TWRP and a few xposed modules. A couple of weeks back after my phone's battery died, I couldn't get it past the samsung logo when trying to reboot after connecting the charger. I suspected a s/w malfunctioning and performed a clean flash, rooted again and installed TWRP. It has been working fine since then until the battery ran empty again this morning. The same problem seems to occur again now. On a normal reboot it works just fine.
I have tried removing sd card and trying, restarting through TWRP and connecting to PC for the restart and none of these helped. I bought the phone from UK and have now moved to India so am not sure if I can claim warranty even if I managed to reset the Knox counter to 0.
I came across a similar thread for i9300 where the asker says he had an empty /efs folder. Is that likely to cause this problem and how can I check the /efs on my system now without factory reset. I'm having to reconfigure the phone with every factory reset and is tiresome. Also if /efs was the problem should the clean flash last time not have fixed it?
Thanks in advance,
Vish

Go to download mode by pressing and holding volume down+home+power, then try flashing the stock firmware again, or if you want boot to recovery first and wipe cache and dalvik and try to boot it again, if not go back to step 1, cheers:fingers-crossed:
Thanks for your reply. I have done it and it's now back to working condition.
But worried that this is continuing to happen every time my battery drains out.:silly:

Good to hear mate, you should try calibrating your battery also, use your phone until it reaches 15%, then charge it to 100%, reboot into recovery wipe caches, boot it again, and let it on the charger 20-30 min after its fully charge, and repeat step 1, keep doing this as much as you can, your battery will calibrate and it will improve in longevity, cheers:fingers-crossed::highfive:
Thanks mate. Will do that!!

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!
Hope someone can help. I had an issue with an app the other day which I think caused my phone to overheat.
Since then I have had a major issue with the phone freezing. I tried to install stock through odin which was fine but the phone freezes during the boot logo sequence, and the stock Rom won't load.
The phone freezes in the Rom, recovery and when booting.
I have managed to install lineage Rom as this doesn't take long to install or boot up. So I have the Rom running for anything from 10secs to about 40secs then it freezes and eventually reboots.
I have had red messages come up saying cannot mount or demount data and system when factory resetting when in recovery.
Is it a faulty part inside or does anyone have any ideas on what I can Do?
Thanks in advance.

Bro post in s7 edge help section, this is for news, guides etc. Btw you can try smartswitch emergency recovery, put your serial no. and model no. there. If it fails too then reflash stock rom with normal CSC and repartition ticked in options, it will delete all data, so back it up before. If it still freezes and reboots after fresh stock rom install, then there is surely something wrong with your phone.

Hi everybody.
Dis morning I woke up and I realized that my phone was gone. I used AOSP Extendend ROM when it happens. At first, the rom completely froze. I thought it was a bug, so I rebooted the phone, but after did dis, the phone kept on rebooting and froze on first screen and I couldn't do anything. Touch didn't respond, nothing worked.
So I tried to go on recovety, but nothing.
At the end, I gave up about take back my data and try to install the stock ROM through MiFlash. I tried different stock ROM, but at the first they works, but during the installation guide they froze again and reboot. I can't even finish the setup!
So I tried again, unlock bootloader, flash TWRP, but still there:
- only TWRP v2.0 works, other versions won't start
- even with TWRP v2.0, after did wipe everything and format, when I tried to install a custom ROM, even TWRP froze and reboot the phone
- TWRP is pretty useless, it keeps on froze and when I boot recovery again, TWRP is locked and I have to format everything again, but still don't work.
Someone could tell me what happened to my phone? Any suggestions about what I could to to install something on my phone?
Pls help me, I am completely lost and disperate
You may in deed have a serious hardware problem.
What you can do without opening it up is to try charging it overnight, and see how it works tomorrow.
You have tried everything else you can think of, I assume, like wiping & formatting everything you can in TWRP, and possibly "repairing file system" if there is such an option.
The next thing I would try is opening it up and disconnecting the battery for a while, then connecting it again to see what happens.

Ok, I will listen your tip. Yeah, I have tried everything but nothing. Technically, I bought this phone last december, so it's still covered by warranty, but I have to send it to China, I would avoid that if I can.
I hoped there would be something that I didn't but...nothing.
Thanks anyway dude
