Random reboots , freezes - Samsung Galaxy S7 Edge Questions and Answers

Hey guys i bought a s7 edge 930F and i get random reboots. Tried installing supermanrom, same result, factory reset didnt worked ether and yes auto-restart is off.
everytime that happens, the screen freezes for some seconds and after that it reboots. Is that a hardware error? and how could i create a log in that moment (perhaps that would help to figuere out the problem)?
Moreover: if i decide to replace the motherboard, will the fingerprint sensor work with the new board?

[Q] Anyone else have Mango lock up on restart

I loaded Yuki's ROM and updated to Mango via Zune. Had it running for about a week before I discovered that when I turn off the phone and then turn back on, it gets stuck at the point where it should be loading the home screen. I get the time at the top and that's it; the phone is completely unresponsive. The only fix I found was to do a hard reset and start over. I thought maybe an application caused this so after the reset, I turned off the phone before loading any other applications. It got stuck again at the same place. I suppose this could be linked to the sd card and I'll try a different one. Just wanted to see if anyone else has experienced this problem.
--Edit--
I've linked my issue to the sd unlock cab. As long as I don't install, mango restarts with no problems.
I've had this a few times.
Usually get the lockup at the SIM password screen.
Just reboot again and it will come back. Sometimes a couple of boots are needed.
I have a supported Sandisk card BTW.
Thanks. I've given it 2 tries before the reset but not more. I'll try to be more patient with it this time...or just avoid turning it off
I had the same problem as well, reflashed it with the same problem. after doing about 3 hard resets it finally worked.
I'm getting this continually, every time i reset i end up having to hard reset...

Factory Reset Stops in the middle: LG G2 stuck in bootloop and can't reset

I have an LG G2 stuck in a bootloop. I've tried doing a factory reset but the process stops in the middle and the bootloop restarts. A few times I've been able to get the phone to work for a few seconds before it restarts itself into a bootloop. I've tried uninstalling apps, changing settings other users suggested for similar issues (such as the default keyboard), and disconnecting my google account (another suggested solution). I haven't been able to get my phone to go into download mode so I haven't tried any flashing approaches and don't think I'll be able to. Any suggestion on how to get the hard reset to work?
What did you do to the phone that caused this to happen?
If you never did anything nasty to it, then I guess it is a hardware defect. Maybe the cooling of the main chip doesn't work so it overheats.

(Help) S5 suddenly goes on a reboot rampage

Hi guys! So I am facing a situation with my S5,it started only a few weeks ago. The problem is my S5 sometimes goes on a reboot rampage, first it would get stuck on some app, then it would vibrate once and then restart again with two vibrations. After that it would get stuck on home screen and keeps rebooting it self in the same manner. And after some time of repeating this process, it would start working properly.
Now I believe it to be related to either a motherboard or a battery problem.
So can you guys tell some way to check my motherboard without opening my device?

Try to flash stock rom via odin.

S7 randomly crashed And hard bricked, “custom binary blocked by FRP Lock”

Phone randomly died after a few days of crashes and cache wipes. Was a preowned phone so maybe old owners have been messing with it? No button combos work, no led flashes however does heat up when charging. Is there anything I can do?
I am facing the same Issue on my Note 5 (SM-N920G), Please help. I also get "DRK missing, Please Install DRK". Tries many things including flashing the combination files and also without cache.img

suddenly boot-loop, maybe after phone fell

ok
i've been usign whatsapp and suddenly my phone went into bootloop,
tried to enter fastboot, recovery
but he keeps on boot-looping after 2-3 sec of showing the fastboot-recovery icon.
i tried disconnecting the phone-battery-motherboard-etc, but he keeps going boot-loop, showing the first load screen, black screen, and so on and forth
any suggestions? never occured to me before , only after unsuccessful flashing, but like this? this is really weird.
i have a custom rom yes, but with it for a few months already , 0 problems.
p.s my phone fell on the floor few days ago, but had no problem since whatsoever
any clues on how to solve this?
i can't even get to flash via fastboot/recovery because it restarts when im there..
what could be the problem? the only thing pops into my head is that the restart key is pressed all the time, but is it possible?
I had the same problem, crazy thing. I couldn't even enter orange fox, got to the loading screen and got another reboot. I pressed power button fast many times and then worked. The power button seemed to be ok. The only thing that i had recently changed was the EAS version of the predator kernel. It may not make sense but i went back to HMP and now it's fine.
well! it worked lol
what is HMP? a kernel?
A type of kernel, the common one. Now i know that was not the reason!
Hello
I have the same problem as you and if someone has a solution, I will be very grateful !
I can use my phone but if I push to the power Button, it bootloop.
