So i have a galaxy s5, was running Cyanogenmod 12
my phone was freezing and rebooting then eventually it was stuck and would only boot into download mode
so i cut my losses and flashed stock 4.2 and 5.1.1 (files from samMobile matched model number) and the problems persist
cleared cache and factory reset multiple times and booting in safe mode doesn't fix anything
the phone freezes on samsung splash screen usually mid animation, sometimes i get to tmobile screen when it freezes.
sometimes it will boot without any problems and work normally for a few seconds then freeze and shut off into the same loop
i have searched and can't find any advice past (flash stock and your good )
oh and knox counter 0X1 (2) so no warranty for this guy.
What a helpful forums
I would recommend taking out your sim card and memory card before doing a factory reset. Once done let it boot and see what happens. If it works ok aka boots fine let it sit for 10 min. Now power it down and put your sim card in only and boot up again. Wait the 10 mins again to see if anything happens. If all good power off and put the memory card back in and repeat. Also do not sign into your google account while doing this. Do not sync anything. Just do it bare bones. If everything seems to go well, then you can slowly start putting stuff on and syncing things. when you notice it starting to happen undo the last thing you change/added. Hope that helps. And remember to be nice. Sometimes it takes a while to get help. Being rude isnt the answer pal. Good luck and hope you had a good holiday.

after all that, doesnt it sound like a problem with hardware? sure is a lot like when a pc is malfunctioning (due to overclock or damage, etc)
my only ideas are try turning it on in cold weather, plugged into wall power, & an extreme case... maybe modifying a kernel to give a little more voltage to the cpu & gpu... the idea is a bit out there, but again with the pc example, there's a chance for it to do the trick, but also chance to accelerate damage IF it's entirely based on usage (but if it's dying already, there's no going back)
my pc gpu failed in an interesting way a few years ago, i was playing limbo of all things, not a demanding game, capped at 60fps, then the whole system froze randomly, so i restart, start game again, froze again, think i had one more go until artifacts appeared on screen & it froze/bsod'd as soon as the driver loaded, a clear hardware death
Same Problem

I am having the same problem. Any other advice. I have flashed with odin F0G6 stock firmware.

GT-I9300 (international version) (FCC A3LGTI9300A)
Never rooted, just applied official OTA patches when delivered.
Been experiencing random reboots now and then (more rarely than once a week) Some of them seems to have been "softer" than others because I did not need to enter PIN when it started up again.
Then a couple of hours ago, when waking it up (screen turned on but froze before displaying unlock function) it rebooted again and got stuck in boot loop.
When I power it on the first screen (Samsung Galaxy SIII GT-I9300) shows and then it goes to the "fun part"
The blue/purple "Circle"
SAMSUNG logo
blueish glow behind SAMSUNG logo (two short vibrations near the end)
black screen
repeat ad infinitum
Managed to get into recovery to clear cache but that did not help.
I guess factory reset is the next step to try but if there is any chance of anything else working I would prefer not to have to reset.
try reflashing the ROM you had through Odin. And don't ask how, there are tons of guides
Thanks for your quick reply!
Would it have to be the exact same version, or is any 4.1.2 for my model "close enough" to hopefully avoid factory reset?
Every ROM should do the job. But when it works you should save the data you want to keep and do a reset afterwards and flash the ROM again. Just to make sure no issues come up. What you could also try is to hold down the Volume Down button while rebooting and look if you can boot into safe mode. There you could save every neccessary data and do a reset/wipe afterwards.
Try to flash modem depending on your region, it worked for me
Sent from my GT-I9300 using xda app-developers app
Thanks for your tips, unfortunately no luck so far, one more rom file to try before resorting to factory reset...
Update, unfortunately still no luck. For a little while (after going from 4.1.1 to 4.1.2) I was feeling optimistic as the "updating apps" screen appeared when booting, but when it was finished it went back to bootlooping. I am now considering rooting/custom recovery to try to mount partitions so I at least can recover data from internal sdcard-partition.
Didn't want to risk triggering flashcounter if I still would not be able to boot and run TA.
Ended up doing factory reset from stock recovery and phone booted up just fine, guess there was something bad in my data or apps.
I have a Galaxy Prevail 2 that is rooted and has a CWM based recovery. Today after watching a few videos on it, I cleared the RAM using the built in Task Manager as I do after using a few apps, then returned to the home screen, turning the screen off. About 20 minutes later I go to check my phone and it has the Samsung boot image on the screen, Sometimes it resets itself and gets stuck there, and it's usually fixed by removing the battery. But now, even after factory resetting from the Recover it won't boot into Android, it just stays on the pulsing Samsung logo, even after 3 hours, vibrating every now and then. It has the stock ROM on it as I can't find any ROMs that are listed as supported. I think the ROM may be corrupted, but I'm not sure. I want to know if anybody knows a ROM I can flash onto it to see if it boots. Please respond with haste, I need my phone working again by tonyte, as i have plans. I don't mean it in a rude way, I just really need my phone.
Hello!
Having a problem with i9300 device.(4.3 rom)
The phone starts up. Can use device for approx. 2 minutes, then freezes,screen goes blank and phone restarts automatically.
Recovery mode does not hang but is kind of slow and does not always reply to pushing volume up/down.
Have tried setting usb debugging on to flash but no use,if phone freezes so fast.
Also tried several times recovery mode-wiping and restoring to factory, but it doesn´t help. Phone still freezes after 1-2 minutes.
May You please offer a solution I could try?
Thanks!
rom?
original rom. phone has never been modded,used only latest update by samsung.I can write exact rom version in the evening.
Boot into download mode and see it happens there. If not then flash the latest stock firmware for your country with odin, factory reset in recovery before first boot.
If the phone freezes or reboots while in download mode then you have a hardware fault.

I will try that in evening and will let You know how it worked out. :good:
Tried latest firmware with odin. Download mode works fine and goes all the way to the end. but after finishing and first boot, setting up android language etc. for the first time, it hangs about 1 minute again.
hardware faulty then?
Yes, it sounds like it -something is breaking down after a little use.
if some part of hardware is faulty, is there maybe some kind of diagnostic tool that I can run without booting android fully up? then I could get to know what kind of system part is problematic. If I'd find out problematic part, maybe there would be a change to modify android rom, so the problematic part of system would be turned off always?
just an idea
I doubt it, even Samsung don't bother with component diagnostic -they just replace the motherboard.
My wife had a similar problem with her phone. I downloaded Dummy File Generator from the Play Store n ran the application. Been more than 6 months now with no lag.
hello everyone, my stock s6 edge on rogers is stuck in a boot loop all of a sudden, fully stock and unmodded, running 5.0.2. i was just walking and listening to music through bluetooth headphones and all of a sudden it stopped, and i looked at my phone and it was rebooting. so i just waited and its still stuck in a boot loop after an hour. it gets to the lock screen sometimes, and then after like a second or 2 just reboots again. i have not tinkered or have done anything to my phone either, and had no issues with random reboots ever, so i have no idea what could have happened
some extra info, when it reboots it doesnt always go to the galaxy s6 edge screen, it sometimes just shows the samsung logo with the animation. i have also tried to wipe cache and that didnt work either. after a few reboots however the stock theme was applied at some point. also i tried booting into safe mode and that also didnt work.
i really dont want to wipe my phone, but i will if it is absolutely necessary. so if anyone has any other suggestions that i can try out it will be very much appreciated!
thanks!

I have had said problem before under the same circumstances (although it was with a different phone)
Try using Odin to install the stock Firmware.
A thread explaining how is right here.
http://forum.xda-developers.com/galaxy-s6-edge/general/sm-g925f-s6-firmware-thread-t3078841
If you don't want the firmware listed in that thread, download from Sammobile.
While some users say it does not wipe the phone, it wipes every time I use it
If this does not work, you should get a warranty replacement.

Thank you for the reply!
weird thing is it fixed itself .. few hours after it started it just booted back up and didnt reboot again, and has been running fine for the past couple hours. but if this happens again i will know what to try next time
So I've reached out to this forum as I've tried a million and one things but can't seem to get my phone to boot.
Here's the situation:
I fell asleep watching a video on my phone and my phone died. I plugged it into the charger and it wouldn't boot, would just endlessly be stuck in a boot loop. Looked it up and saw this is a common issue. Went through the standard fixes:
Wiped the cache
Factory reset the phone.
Attempted to boot in safe mode. (Wouldn't work, still boot looped)
After all this failed I thought I would just flash it using Odin v3.14. T-Mobile is my carrier and I'm based in the US so I used this firmware: SM-N950U TMB, LINK(https://updato.com/download-samsung...sa/sm-n950u/B094B9DAF04A11EAB4A2FA163EE8F90B/)
It still didn't work after this. It booted up and the startup process began asking me to agree to the terms and conditions. Before even getting to agree, the phone crashed. I tried this again and it just kept failing and crashing. I did this all while plugged into a charger. What I did begin to notice is that the phone would get hot on the left side, where the battery sits. I'm not sure if this is related to the crash or just the fact that its been discharging and charging a lot while I troubleshoot it. I have tried different firmware as well just in case I had the wrong one, but nothing has been working. When I update the firmware I used the CSC file and not the HOME_CSC and I also use the USERDATA file since at this point I kind of accepted I'm not getting my pictures and files back and I'm just trying to get the phone to work once again, thus just trying to factory restore it. Also, when the phone does start booting it says optimizing apps on the bottom each time I boot it I feel this number is changing. I'm not sure what else to do or if anyone has any suggestions? Thank you in advance
