Help - Freeze / Reboot Issues G935F - Samsung Galaxy S7 Edge Questions and Answers

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.

[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

Phone won't boot past "Galaxy S4" splash screen

So I recently purchased my AT&T Galaxy S4 with MDL baseband. I rooted and installed TWRP via motochopper. I then loaded Kangabean 4.2.2 and everything was great. Got notification for OTA update to 4.3 and decided might as well load Kangabean 4.3 as opposed to dealing with the OTA notification. I did so (after formatting internal SD and performing factory reset) and now my phone won't boot beyond the Galaxy S4 splash screen. I restored a nandroid backup of the original software and was able to boot the phone once, but couldn't load the custom rom again, nor can i load into the stock rom anymore either. Does it sound like my phone may have a hardware failure? Would attempting to restore through odin be the next logical step? I'm by no means an expert with these sort of things but my S2 has never given me any sort of grief when flashing various roms in the past. Any advice would be greatly appreciated. Thanks in advance!
Try a different kernel, also, pull the battery for 5 min, it will boot.

Yeah I left the phone off with the battery removed all night - didn't want to boot this morning. I'm also noticing an oddity with TWRP - it's for some reason asking for a password on startup even though I've never set one. It also gives an error when attempting to wipe the phone or re-flash
id try odin
Don't Odin yet. If you can get into recovery see if you can flash a new recovery onto the phone. Try this http://forum.xda-developers.com/showthread.php?p=41746967

It will not let you past the password, been there, it will only do simulated flashes.
Odin is his only option.
So I managed to flash back to stock with odin. I was then able to re-root and re-install recovery. Something is still wrong here though. I was able to load kangabean 4.3, but when i installed the SIM card (kept it out to prevent OTA updates) the phone would no longer boot. I then re-flashed with odin, re-rooted, installed sim, THEN loaded the rom and it worked.... For a while. I had the phone plugged in to my laptop as i had recently transferred some ringtones to the internal SD. I powered down the phone. It seemed to shut the OS down but it then displayed a battery symbol with a rotating circular animation, as if it was trying to show that it was charging the battery. The phone froze in this state.
Another thing that I've noticed is that when this phone freezes, it gets warm. It also tends not to respond well until i've let it cool down. I'm now having difficulty booting the phone after re-flashing with odin. It loads to the white screen with AT&T logo and hangs (and gets warm). I plan to leave the phone alone with battery removed for the day and attempt to reboot or re-flash with odin later.
I find it odd that the rom that i flashed would stop working if i've flashed the rom with the sim removed from the phone, then introduced the sim to the phone after the flash is complete. Is this normal? I'm also unsure if my phone has faulty hardware, or maybe there's some sort of software glitch that's causing it to hang and overhead (like an infinite loop caused by faulty software).
I think if / when I can get it working with the stock rom again, I'll root it and run it for a while and see what it does. I never intended to run this phone with the stock rom as I prefer vanilla android.
I'm wondering if there's something wrong with the kernel. Perhaps I should re-download the ROM and re-install it. I'm not sure but I think the kernel is responsible for charging issues. Perhaps a bad kernel WOULD explain why the phone sometimes freezes at the "battery charging" logo? I'm somewhat at a loss as to what to do. I could try exchanging it through AT&T. If so, I hope they nave another one in their stock that has the MDL baseband as I know I'd be screwed with the current one...

If you're on the stock AT&T rom and you're getting stuck on the AT&T boot logo try the following:
Power off your phone and hold down Volume Up, Center Home, and Power buttons together.
Once you see the Galaxy S4 splash - Keep holding down Volume Up and Center Home buttons but let go of Power button.
Choose the wipe datafactory reset. This will wipe your phone completely but it should boot after.
Hope that helps.
Well I've been toying around with this thing and much to my surprise, I have CM10 running stable w/o any issues booting! I think I would prefer to run Kangabean 2.05 (android 4.3) though. Assuming that the kernel could be a likely cause of the OS not booting, could someone recommend a suitable kernel for that rom? It appears to come packaged with the "KT" kernel...
Another thought i had was perhaps TWRP wasn't adding the loki feature to the roms that i was trying. I upgraded from 2.5x to 2.6. Hasn't seemed to have made a noticeable difference though.
Would the fact that CM10 runs absolutely flawlessly with no issues booting at all possibly help narrow down why the other roms that I'm flashing only load up the first time but fail at the "Galaxy S4" splash screen on subsequent reboots? Admittedly I'm a relative noob to roms and such but up until now i've been able to muddle my way through things and eventually figure them out. I'm not having the greatest luck with this one!

TWRP does not now and has never added LOKI to any ROM or Kernel. Only OUDHS CWM auto-LOKIs. You have to use A pre-LOKIed Kernel or flash the LOKI DokI script to LOKI anything with TWRP. You can do a search to find the LOKI DOKI script and how to use it.

[Q] S5 Reflash - acore has stopped working REBOOTS

Hi
I reflashed my S5 with a stock rom to remove all the Carrier blocks and extras. After the flash the device booted up and instantly came up with the error saying acore has stopped working and then around around 5-10 seconds the phone reboots and does it again. What can I do?
Thanks

It's hard to answer since you provided no crucial details about your phone, configuration or how you flashed it.
You didn't tell us which S5 model you have or your carrier. Nor what firmware file you flashed, so we don't know if it was a compatible file. No Odin log, so we don't know if the flash had errors or not. And you didn't describe how you flashed step by step so we don't know if you missed essential steps.
At a guess, try wiping the partition cache from recovery mode. Then if necessary, do a factory data reset as well (will delete user files!). If you have ongoing problems, then you should restore your backup and try again from that stable condition.
No backup? That is a bad habit to say the least. In that case, flash a full stock firmware image that matches the carrier that the phone was originally sold for.

The Model is SM G900F. Its On Three Carrier. I Flashed A STOCK (From SamMobile) Firmware 4.2.2.
The Flash Process Was Successful. No Errors.
Put Device In Download Mode
Connected To Computer
Loaded Firmware Into PDA
Ftime reset
Auto Reboot
Started The Flashing.
Completed.
Phone rebooted. Got Acore has stopped. Then the phone reboots.
But since I needed my phone working quickly I took the path of factory reset and that seems to have fixed it. I did try clearing the cache but no effect.
I believe I know the issue. I used a launcher called Themer. I have reasons to think that was causing the issue because as it was loading in the background I managed to quickly hit the continue button to close the crashed process boxes and as the Launcher finished "Loading" it when it rebooted.
WARNING FOR OTHERS. Always Remove Other Launchers Before Flashing As A Precaution! (Warnings From Newbies Hehe)

Phone crashing and shutting down randomly when not On charge

. For the past few days my phone has been crashing and turning off randomly, when the phone is off the charger. The screen just goes black and Shuts down. When I try to reboot the phone it will get upto the boot animation and then freeze and shutdown again. I have to connect my phone to a charger and then reboot, only then does it fully boot up. My battery is 100% btw.
What I have done so far is:
1) flashed the latest build of exodus
2) cleared dalvik and cache
3) flashed an earlier build (25/07) without flashing XPOSED and SUPERSU. However problem still present.
Can someone help please and tell me what other steps I can take. My phones important to me at the moment as I'm away in Turkey for an internship. It's a really strange problem I can't figure out what to do. Thanks alot
Did you try to go bacm for stock oneplus OS? Try to do a full recovery via the tool it will wipe root twrp back to stock. It may help.
Does it happens with other roms?
hi, i solved the problem by flashing stock oxygen. i tried flashing oxyslim and cyanogen however both of them still had the same problem. Anybody have a idea of why this might have happened? it was completely random, and if it was the kernel then it would have been solved when i flashed the other roms...strange

It could be that te ROMs u DL were corrupted. This happens, thats why is always good yo verify HASH from your dl ROM and HASH from the developers topic
So you haven't read up on the official CM13 thread about the latest unstable builds?

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..
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.
