[Q] Rebooting every time after about 30 seconds of use - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I've got a Galaxy Tab 10.1 wifi and installed cyanogen mod on it. It worked fine for quite a while but now it's rebooting after using it for about 30 seconds. I've tried reinstalling the cyanogen mod version I was using and also installing other version but keep seeing the same behavior. Any ideas what I can do? Can I check certain log files to see what is causing the reboot?

[Q] I9300 hangs/reboots randomly

Hey,
since about two weeks my i9300 keeps hanging/rebooting randomly. Today it crashed thrice after about one minute after rebooting but the song that was currently playing finished. Just after that, it hang and did nothing. When the phone hangs all I can do is manually force it to reboot. Sometimes it just reboots out of nowhere. This happens mostly when locked and not being used. The logcat is pastebin.com/QdjjrJMT and the dmesg is pastebin.com/bXDJ0fXK Anything that I can do?
Thanks in advance.

Had the same problem weeks before and solved it with another kernel type. Here are many on the board that are worth to give a try
I have three new logs (connected wirelessly to the device for debugging as it never seems to crash when connected via USB) and left adb logcat running until the device crashed, maybe they help:
knubbig.de/f/log.txt
knubbig.de/f/log2.txt
knubbig.de/f/log3.txt
Am not allowed to post links, sorry.
Would be nice if I could keep everything I have and just solve the problem. Thanks.
I have the same problem for a week now. Was on CM 10.1 nightly 14/03/2013. Complete reinstall and wipe didn´t help.
On Saturday i had 15 freezes/reboots in a row...
Changed yesterday to ParanoidAndroid 3.1 and so far only two freezes this morning. I´m still wondering if it´s the hardware or the software...
freeze
I am having the same problem for 4 days. I used mega wipe , installed 5-6 custom roms but it still freezes and today it started to reboot randomly.
8 reboots/freezes this morning. Other customs doesn´t make it better.
I´m trying a stock rom now and putting it back to warranty status.
I think (at least it seems) I solved it by going back to stock, then re-rooting via cf-auto-root and then installing cm again. I got it to the state i had 24 hours ago with crashes only last evening and it hasn't crashed since.
SGS3 GT-I9300 random reboot all the time, no complete boot.

Hi folks.
My SGS3 had a workshop replacing the motherboard some 2 weeks ago, right the way i installed root and setup "Siyah-s3-v1.8.9-CWM" With UltimaRom v.10 on primary rom, "FoxHound_Rising_2.3_Full-Essential_JellyBean" on the second rom.
This worked great for about a week, then the phone out of the blue starts rebooting all the time, for hours and hours or until it runs out of battery.
No Stock recover through Kies can solve the problem With reboot.
Try to reflash With various roms through Odin With, Aroma installer starts, let me choose the options best suited for XELLA build and after aroma setups is finished and the phone goes on With rom setup, after 2sek or when setup starts or try to start it goes to blackscreen and setup dies.
Have tried many kernels and roms, but the Device is dead.
Any ideas on where to start looking?
Thanks a lot for Your time

Since I flashed the stock rom yesterday, my problems are also gone. I´m trying today a custom rom again.
Stock rom seems to be solving this issue.

I had the same issue. At first I thought it was the SDS fix, and then it stopped right out of the blue. I'd suggest just using it for another week or two. If it doesn't stop, let us know and then we can maybe find a solution.
Usually it's caused by the phone calling a memory block which is faulty, the fix then tells the phone to stop and it crashes, to save it from dying.

It´s not as simple as you say. Stock is running fine. But whenever I flash a custom rom, I get random freezes after some time.
But only a few freezes, not nearly as many as before...
So, the freezes are now gone since six days. Flashed a stock rom 3 times in a row.
It´s running fine like before, and i´m gonna stay with stock rom for a few days more to be sure.

S3 keeps crashing

Greetings,
around 6h ago my S3 (CM 10.1 nightly) began crashing. In the beginning i thought it was some error with cm and downloaded the new nightly but the frequency of the crashes got worse and now i cant even boot to cwm because as soon as the cwm screen appears it crashes again.
Has anyone an idea what i could do?
what's your definition of a crash?
well you could flash a full firmware I guess that should solve it.
Thanks for the answers,
with crashing i mean that it's rebooting instantly as soon as the cwm screen appears.
How can i flash a new firmware? If i want to use the download mode as soon as i press volume up the battery loading symbol comes again
Flash a different CWM and Root .

Serious issue with Galaxy S3 i9300 NEED HELP

I was running CyanogenMod 10.1 on my GT-I9300 for several months and it worked great. But the other day I was using Google Navigation as a sat nav while driving and the battery went to 1% and the phone froze. Tried hard Reset ect but ended up having to remove the battery to turn it off.
When I had charged the phone I was stook at the Samsung Galaxy S logo screen and would not boot. I tried everything and several roms to get my phone back in working order.
For some strange reason I can only install CyanogenMod 9, which the wifi and mobile does not work at all so its of no use. When trying the CM10 builds I get stook at the same screen and if I use a Stock ROM I get stook at the Samsung blue animation logo in a boot loop.
Any help would be deeply appreciated.
Tried a couple of other roms installing through Clockwork Mod, including Phenom but only the CM9 one works.
Also just tried the KIES firmware installation, installed fine but on first boot its back into loop

[Q] Phone Freezes

Hi to everyone..well..as the title says my phone keeps freezing after seconds it boots. i was on PA v3.6 and decided to flash the newest release so i did.. after that it's been only problems. i did the wipes, but it constantly freezes.. so i decided to go back to stock and try again.. so i did with odin, but it keeps freezing even when the first settings pops out. i don't even install any apps. it just freeze, even if i reboot the phone and leave it to deep sleep i find myself with the same problem. i've been flashing custom roms since i bought the galaxy s1 and i never had any problems. i tried the dummy file thing but it keeps happening. does anybody knows how can i fix this?
Freezing is usually the memory controller working around bad memory blocks. Try reading the 'unusual freezing' thread in the general forum.

Random Reboots Galaxy Tab S3

Hi, I would need your help, I bought this used tablet (Samsung Galaxy Tab S3 sm-t825 with latest update Android 9.0 Pie) a year ago, after a few months it started having problems with reboots and freezing. During its normal use, in charge and in stand-by, the tablet restarts and most of the time it enters the boot loop for a few minutes, while other times it only restarts and works immediately as it should for a while, sometimes days and sometimes a few minutes. I tried to do numerous factory resets, to reflash the original system with odin, to use the tweaked rom found here on xda and also to clear the cache several times, dalvik, etc ... but nothing worked, I don't think it depends on any app because sometimes the freeze also occurs during the first configuration screen. I have no more ideas on possible causes and solutions, so I ask for your help, hoping that someone can help me solve this strange problem, feel free to ask questions and comment, maybe it could also be useful to others, thanks.
I'm also having this issue, did you manage to find a solution?
I had to flash the latest update just to get my tablet booting and then it took me many attempts to get through the set up wizard.
Now the tablet boots and runs normally for about 5 minutes then restarts.
same here any fixes?
