Phone is rebooting several times - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I have tried to install several roms on my I9100 phone.
Sometimes the roms are working for a couple of hours and than it starts to reboot continuously...
All other times it reboots every couple of minutes...
I already installed several roms:

My phone is rooted, CMW has been installed and i tried to clear all caches and did a factory reset as well.
Do you have any ideas?

Did your phone reboot like that while using the stock ROM?

- The make of your phone. There are many different variants of your device. I9100 G/M/P/T -> I9100
- Are you rooted/unrooted? -> rooted
- What rom you are using? -and- What kernel are you using? -> CMW 5.1
- Have you flashed any mods/scripts/themes? -> NO
- Have you done anything to try to solve your issue? -> Re-installed ROM, deleted cache, factory reset

I used to have this problem + sod like crazy rendering my phone unuseable. Sent my phone into Samsung 2 times for warranty and both times it came back with the same issues. I then decided to reformat my external sd and boom, problem solved never had sod or reboots since may this year. I'm not sure if this will work for you but it worked for me. Give it a try you got nothing to loose

Thanks.
I have edited my post and added more info.
So... is this solved?
I guarantee if it isn't it would be by wiping data/factory reset + wipe cache + wipe dalvik cache and flashing the latest version of a reputable ROM.

I think so as well. If not fixed by that then the only other alternative is a hardware fault.

I have done these three wipes befor flashing the last rom.
But could you suggest me a reputable ROM. and post its link please.
Well it sounds like an .apk problem.
Try: WanamROM for stock or RootBox2.1 if you want to go down the AOKP/CM10 route.
> G S II Android development. I'm sure you can find them yourself.
What is an apk problem?
I am having exactly the same problem with my Samsung Galaxy S2. I bought mine at T-mobile, it is a T-mobile branded phone, less then a month ago.
I did a factory reset a couple of times.That did not help.
I have not flashed my phone or anything like that. I do not even know what flashing is!

Try to do one of these solutions for the problem
Settings) application) running services) show cached process) camera) stop and clear data. Test your camera.
or
Settings Select Applications / Manage Apps Select Manage Applications Select All Select Camera and/or Android Camera Select Force Stop and Clear Data Turn your device off and back on. Test your camera.
or
If that did not work, please do a Google services reset:
Please go to Settings Select Applications Select Manage Applications Select All Select Google Services Framework Select Clear Data. Turn your device off and back on. Test your camera.
I still have the problem but maybe it will work for you.
I hope it will
Thanks a lot for your advice. Unfortunately it didn't work
What I find weird,is if I clear all data,it says 0.0 kb but after restarting my phone,it says 4.0 kb. Like it didn't cleared any camera data?
I am afraid there isn't anything left for me to do then go to a Samsung servicepoint....

I deleted all the files and directories in storage and then did a factory reset.
After that I can use the camera for a short while.
When I rebooted the phone, the camera goes blank screen again :crying:
So, anyway, this is likely a software problem and not hardware.

Are you quite sure its a software problem?
I've been facing this quite a few months. Problem started a few months after rooting with CF-Root and flashing Cyanogenmod 9 nightly(was working fine for few months). Since then have reflashed kernel (tried many Siyah kernels). It would work a while then become black screen again then again work sometimes.
Flashed Cyanogenmod 10. Would work intermittently now and then.
Finally flashed to stock official ICS ROM. Didn't help. Works for a while after the wipe and again a while if i do factory reset. But problem still persists.
Let me know if you find a solution. I'm really frustrated

everything supeeer slow after changing the stock rom

I brought my galaxy note from ebay. came woith ginger bread and older cwm. Flashed it latest CWM with Black star first. It was heavily unstable the screen would take 5 minutes to even startup an app. tird Liquid rom, same results. The jedi rom same results. Tried cm-10 got the dreaded status 7 error. Flashed TWRP with same results. Can someone tell me what am I doing wrong
1 wipe dalvik, cache, system
2. flashed rom
wipe dalvik, fix permissions
with no avail. Can someone please help
Try flashing back to stock ICS with Odin. Then root and do all necessary steps. After you do all that DL the ROM you want and wipe data, cache, wipe system and dalvick cache. Now flash the ROM. Reboot phone, let it sit for at least 10 minutes. Try that and see if it helps.

Just finished trying that. flashed the stock back in but now the stock has also gone unstable. even small things like accessing the settings menu causes a reboot. Almost turning into a nightmare. Thanks for your help
Are you using correct technique? A factory reset the wiping all caches? What baseband is in the About Phone?
The fastest way to recover is to use Kies firmware and initialization to clean it up.
I read through many threads and followed the technique described there in but seems like when I flashed the black star rom something messed up. I am unsure what. Is there any way to get the phone to the default state? Thanks in advance for all your help with this nightmare

Yes, that is a t-mobile modem. If you are at&t you want the LF6 modem.
Kies emergency firmware recovery will restock your phone.
Thanks to all for your help.

http://forum.xda-developers.com/showthread.php?t=1731654worked like a charm and got back my phone.
Even though I have the ATT baseband LF6 Tmo calling sill works fine

I had the same problem but the AT&T guy had me call the AT&T support line and they sent a replacement without even asking me to do troubleshooting.

I'm assuming you have a P7510 as I have no idea what a P7010 is. However, that's probably unimportant.
If your tablet is that unstable, I'd install stock along with wiping data and cache. Don't reinstall any applications. If that doesn't make it stable, it would seem to be a broken device.

Sammobile.com has every stock rom you need, what you have to do is to flash the factory recovery e3 again and factory reset with the factory recovery, then flash cwm or twrp and your ROM again. Do not install any apps until your sure that it's fixed, if so, install the apps one by one and if something messes up, you know who the culprit is

[Q] Bootloop after Battery Pull

Sometimes if my phone freezes up and I need to do a battery pull my phone will randomly bootloop. This has happened to me about 3 or 4 times on all kinds of roms, tw and aosp. One time on a tw rom it ended up booting into the samsung setup wizard. It was weird because it didnt wipe my phone but all my apps were force closing if I opened them. The only fix was to wipe and flash again. This happened on Nephilim rom last. Also this has happened on several kernels. Has this happened to anyone else? Do you think this could be a hardware issue? Thanks in advance.
It's to my happened to me with certain ROM installs when I flashed dirty/without doing a factory reset prior to flashing.

No for me it had nothing to do with that. I could be coming from a clean install and pull my battery and my phone would just bootloop

Odin to stock and see if you can make it happen. If it doesn't happen on stock then it's something you have done while flashing. Are you using sd swap?

I mean I fix it by flashing another rom so I don't need to odin. Everything is okay so far. And no I'm not using SD swap. Just wanted to see too if anyone has experienced it. I have a feeling it has to do with my device I may get a replacement

Note 2 rebooting

I have a note 2 that I kept stock for a long time. And decided to root it about a week ago. I used the latest casual one click root. And it seemed all dandy initially until i went between a few different roms and it decided it wanted to shut off randomly and not boot back up past the note 2 screen on its own. But the odd part was it booted while connected to the wall or to the computer. So I flashed to 4.1.2 stock via odin and the issue still remains. I can only use it fine on charger. Is there something else im missing on flashing back to stock?
Sent from my SCH-I605 using XDA Free mobile app
Hmm when you installed 4.3 did you do so wiping everything could be an app causing the problem. Try it from brand new with no apps installed and see if that helps. Could be also a radio issue as well.

Yeah I wiped everything. Actually used odin twice to revert to stock 4.1.2. I tried a few cm nightlies before it began. Is there anything else I should flash on top of whats already been done?

I've found that even after using ODIN to go back to stock 4.1.2, that there's still leftover data on the phone from custom ROM's. I've read where others had the same issue. I don't know why Odin doesn't seem to fully wipe everything ... but this has been my personal experience.
The way I've fixed this (and all this may not be necessary).. . is that after Odin'ing back to stock 4.1.2, I boot into stock recovery, then do a full factory reset and wipe cache. Then I booted into the stock Rom and used the bypass setup trick (touch the left side of the screen right above Emergency... then right side, then left, then right again, and then volume up... this should bypass setup to save time).
Then went into phone's settings and performed a factory reset from within the stock Rom too...
Finally... (because I'm a bit OCD... so this is probably not necessary), but I ODIN'd back to stock 4.1.2 one more time and then proceeded with using CASUAL again to root /unlock the bootloader).
I know this is a pain in the butt... but this has worked for me. Maybe others will have some better suggestions.
(Edit : Forgot to mention that if you're not wanting to return to stock to start over again... check out this thread (http://forum.xda-developers.com/showthread.php?p=53624921) on how to flash a stock recovery for the purposes of doing a proper data wipe... then can you odin your custom recovery back to the device without having to fully restore to stock... this can be a real time saver. Please make sure to thank the OP for the helpful info).
So in the end I tried to reset from stock recovery and wipe cache. Than do a reset from the settings and the issue presisted. But now I have root and recovery as well. So I may give a rom a try.

This is totally a guess, but I'm thinking that you may have a battery problem... and it's just a coincidence that these problems started happening around the same time that you rooted. You may try replacing the battery to see if that fixes things.... (you can get one pretty cheap off ebay or Amazon).
Yeah thats odd. I had bought another battery from a phone store I use to work at and have no issues now, back on 4.1.1 rooted.
