[Help] My phone restarts - AT&T Samsung Galaxy S II SGH-I777

Well, I have a problem and would like to help me, will tell you.
Yesterday I was using my phone normally as usual, I was listening to music and texting suddenly trailed off alone, and now I just reaches the logo of Samsung Galaxy CyanogenMod and restarts and does the same and will not start, only goes up there and restarts.
What happened? I have not installed anything weird, I have not done anything unusual.
I have the room CyanogenMod 10 Rooted, had never given me problems until yesterday.

My first guess would be your power button going bad, because random reboots like you described (especially on stable, older roms) just don't appear out of nowhere.

SGS3 keeps rebooting randomly

My SGS3 works just fine for 2 weeks, until now.
Suddenly, it keeps randomly crashing and reboot into samsung s3 logo screen.
Oh, I have tried different roms (and stock rom also) but the crash still happen.
I also have tried wiping cache, dalvik, clean install, removing external sdcard, and restore factory setting. But none was effective.
Any ideas?
I had a similar issue with my Atrix and it turned out to be the SIM Card. Had it replaced and no more random reboots. I figured this out by checking the panic dumps...maybe there is a similar way to check this on the SGS3

Thanks for the response.. I tried it just a moment ago without sim card, and it still got the random reboot..
Any other people who got the same problem?
Is the phone unusually warm? The phone will automatically reboot if it overheats, but that wouldn't normally happen unless it's been left in the sun or overclocked.
I can get mine to go into a reboot loop if I play Asphalt 6 while outdoors, but the problem goes away as soon as I let it cool off for a minute or two.

yes, the phone (when i use it) is usually warm, but my phone also crashed while not in warm state.
but this crashing-reboot problem just show up after 2 weeks of normal (and not any crash experience) usage.

Sorry to hear that man. Had a SGS with same issues. maybe Samsung has hurried releasing galaxy S3
I'd factory reset and only put on the important apps you use. Depending how long it takes for you to normally get a reboot you can slowly add new apps back to narrow it down. I had the same problem last year and thought I had a bad sgs2. But it turned out to be dolphin hd browser at the time that caused it and haven't had a reboot in a year. It could be something similar in your case. Hopefully its software related and not hardware

i just tried flashing normal ROM, after booting to "get started" page, approximately 3~10 seconds, my sgs just rebooted over and over again, until it show only black screen with battery icon on it (i think it may be charging animation while the phone is turned off).
ahhhh this is driving me insane!!
update : i just flashed hypergalaxy ROM and currently it is stable and not experienced crashing (yet ).
i'll give further report later today

Have you tried reinstalling FW with Odin? If yes does it still reboot after a factory reset with nothing installed?
yes, i have tried flashing stock rom using odin a few hours ago, but the crashing still happen.
my sgs3 now stuck at boot-standby5sec-crash-reboot loop.
so, i decided to bring my sgs3 to samsung service center tomorrow. hope they will replace it with a new unit
UPDATE : Samsung replaced my new SGS3 with a new hardware (not sure new device though, the flash counter reset to zero )
the problem seems to be hardware related
thanks for all your reply to my problem

I am having the same issue, I've had my phone since Saturday (6/23/12) and it crashes, reboots, apps crash, internet crashes, email crashes, etc. I can udnerstand a lot of apps may not be updated to ICS.. but no matter what I do.. everything crashes.. It's a bit ridiculous. I am a prior iPhone 4S user and am probably going to return this phone. I can't do much without it crashing or the screen freezing.. not being able to do anything for 2-3 minutes, etc. And they couldn't port any of my numbers from my prior phone because they didn't have the software update to do so yet. So overall, bad experience with the Galaxy.. and maybe I should have waited longer before buying this phone to work all the problems.

I'm very sorry that u have these problems.but there will always manufacturing faults when making so many units.only one thing to do,return it and get a replacement.when u get a fully functional galaxy u won't regreat it,it's a awesome phone.Samsung usually replaces the phone,so I think they will do the same in your case.anyway best of luck
After all the problem I've been through, finally I send my phone back to samsung service center.. they tried to reinstall stock rom several times, and in the end, they change the IC board to a new one.. and it does solve my probs..
SGS3 tebooting
Hi guys here is a peace of my experience
Bought the phone last year in November .2 weeks everything fine then it starts rebooting itself.retun it to the mobile provider and get it back in 3 weeks with conclusion that they experience the reboots as well and that the phone had some kind of software issue.in 3 hours i was back in the shop with my phone rebooting again.they send it again to service got it back yesterday with 4.1.1 android and they sad it may be caused with wrong customizing or not supported sd card,turned on the phone and had few reboots manage to update to 4.1.2 and today heavy gaming internet etc and no reboots so far.will test it till wendsday and see what happens.if it will reboots again then its going back to service and this time it is the 3 time so i will get a new phone.

Phone randomly freezes

Hello everyone!
A few weeks ago my phone started freezing randomly when navigating through menus, when turning on the screen or just during stand by. It reboots almost every night and I find it in the morning in the "enter pin" screen. I have been using the Omega Rom series for a long time, and I was using v38 when this began to happen, but by that time I had already been with the same ROM for a long time with absolutely no problem. Yesterday I updated to v39 and the phone is totally unstable, it freezes every 5 minutes and I have to remove the battery.
How can I know if this comes from a hardware or a software problem? Is there any way to log what the phone does so I can check what goes on by the time it freezes?
Thank you very much.

you could try to do a logcat report.
did you try different kernels?
Yes I did, I tried the stock kernel and Siyah too, but I get the same problem. Any other recommendation?
I will get started with the logcat thing, I hope I can find something. Thank you!
My droid4 kep doing the same exact thing when I attempted to listen to my music player, and I ended up finding trojan and I didn't find it with any of the AntiVirus' that you find on Android I ended up finding it with pandas usb vaccine when I plug the phone in to the laptops usb port.. And it doesn't do it at all anymore
I tried 3 AntiVirus ' from Google, AVG + lookout+ .AND avast..!!! Nothing picked it up. :banghead:

if it is not the kernel, I would try to setup the phone from scratch with first, a stock Samsung rom, see how it goes, and if anything is ok, flash a custom rom and test again.
Usually, for me, I do not stop with just a factory reset but use a "mega" wipe to delete (not format) anything related on the phone even if some think this is not necessary.

Hi.
I've been having similar issues for over a week now. And have removed some programs and setting trying to find the cause. Eventually what has prevented freezing is when I turn the screen power saving in power saving settings on. I'm thinking the GPU might be somehow damaged or something.
I have only installed the official updates to the phone. Currently I'm at 4.1.2 NEE.
Ive been using custom roms for ages but got fed up with apps and certain not working so I wiped everything and installed stock ics via odin, I then upgraded all the way up to 4.1.2 via the Samsung upgrade utility but....... now my phone freezes sometimes ive never had this before. ...? Im on ella btu

I have been doing further investigation and I've seen that it is not that the phone freezes, it is just that you cannot have any interaction at all with it. The screen is blocked, the buttons do not respond and the phone does not make any sound, but I know it is alive! I know it because whenever an app is doing something, after restarting the phone by pulling out the battery I see that that process has been completed or if I dial my own number from another phone I get tone, although the phone appears to be completely dead...
Does this situation have a name and a specific solution...?

random freezes (with CM roms)

Hi, I had CM10.1 running for a while. Since a few weeks I got random freezes when I wanted to turn on the screen it stayed off (LED was flickering, so the phone was still on). After a forced reboot (vol up+power button) it worked, but as it kept happening I wanted to try a full wipe. By the way: it happened every single night too, my phone was flickering its LED, but didnt react, and also alarm wasnt working (FML).
When messing around with this (I'm not really an expert at flashing/CM) and trying to restore my phone with TitaniumBU it kept freezing when working (to) fast. So I tried a lot with formatting SD, doing other wipes etc. Nothing really seem to help, as the random freezes kept happening.
Now I've installed the stable CM9, but already had freezes (even with the startup wizard in the beginning). I'm getting the feeling that its some hardware related issue. Can anybody tell me more about these problems, and mayb what else I can try.
Last try is to turn it al back to Touch Wiz, unroot, but I have to figure out how to. Hope this will solve it.

Sorry, plz move my thread where it belongs (im noob).
After some searching I found that it might not be a CM related problem, but something with 'sudden death' happening to more people with other ROMs or even without custom roms.

New development: my phone is now stuck at Samsung GSIII logo. Doesn't go further from there. I'm planning to go to Samsung with it. It is not unrooted, so my Q is;
can they see that it is rooted when the phone doesn't get past the boot logo?

Constant reboot not caused by rom

My note started doing this after it went through airport security. It was in a bag and went through the x-ray machine. It randomly reboots very often, probably between 20-60 second intervals. I was on CM10, then I flashed back to stock ICS, and then finally up to the official JB update. None of which has solved this problem.
i posted in here.. this may help.

Phone is stuck in a boot loop and this is what I know so far. Phone is on stock ROM, power button is working fine, I can get to recovery and OS and download mode, and while phone was charging I took the battery out and the phone keeps vibrating. I now know it's a hardware problem for me (I think), but I can not pin point where. Any advise would be helpful cause I really love my note and this is just breaking my heart.:crying:

[Q] Help LG-P760 frequent crash

LG-P760 stock Android 4.1.2
Only basic apps, FB, gmail etc.
1. Factory/hard reset
2. Works around 3-4 days perfectly, then starts to crash.
By crash I mean black screen, nothing helps, only battery pull.
3. After first crash, starts crashing more frequently. Happens only in standby.
Worst was today: If I start phone, log in, then it wont crash before I put it in standby. First time in standby, within 30 second, it had crashed.
twice crashed when someone tried to call me. Vibrated once, then crashed.
I would like to avoid replacing my phone.
Any ideas how to find the source of this problem? Any recommendations?

I had the same problem with Vietnam Rom and it was the baseband. I changed to the baseband from ICS from a Rom of my country so I have Vietnam Rom+Original ICS baseband and everything works well.
Thanks.
Although, I understand it mostly is problem when you have unlocked bootloader.
I am running stock everything.
And they have problem with rebooting phone, mine crashes and freezes.
Weird is that it starts around third day of normal use.
I think I have to take on a quest with a warranty. Does anyone know, can I contact LG straight without the provider, where I bought the phone?

I haven't unlocked it. The problem was the same: SOD sleep of death, when the screen goes off you can't do anything but pull the battery.
But if you can use the warranty use it. You should find the warranty info in the box to know where send it in your city.

Thanks. I will search into it. Sleep of death is new expression for me.
I only have phone, it came from relatives who threw away receipt + box.
Luckily I managed to get new receipt from provider yesterday (I dont think they usually give out receipts twice), so now I can use local warranty.
Thanks everyone for replying. I will post update when I have final solution.
Since you are stock you might want to consider flashing the kdz to see if that helps. Good luck!

I'm having the exact same issue with mine. I've heard everything from "try a different SD card" to "factory reset," and nothing seems to permanently fix the issue. What I've found kind of sort of works is just reboot it a whole bunch until it finally comes up and doesn't do it any more. From there, I'm good to go until the battery runs out or I need to reboot it because all the bloatware is causing it to glitch. This usually means that I have to reboot my device 10+ times in a row every few days. Hopefully, you found a more viable fix than this.

Hi
I managed to kind of solve this issue. Because I am not sure how, I haven't closed thread yet.
Anyway, I warranted device, they re-installed soft. Came back, same thing. After around weeks use, SOD. Factory reset. After that, things went interesting.
I tried not to leave it idle. Always had something running. I also had noticed by the time it never occurred when it was plugged in or music was playing.
One day it did it again, but I was in a hurry and just disregarded it. I did something(I was busy, maybe just plugged it in automatically?) and it came back up. It took like 10 sec for screen to start, but it did just wake up. And it haven't had crash ever since. I have no idea is this solution or is this just some coincidence and I am not keen to factory reset again, to see will it reoccur. It's my only phone
TLDR: Managed to get out of sleep of death, haven't reoccurred since.
