Galaxy S2 turns off - Galaxy S II Q&A, Help & Troubleshooting

Since a few days my GS2 (rooted) turns off after rebooting.
When I change battery or put it to the charger phone will turn on, but will shut off after a servable time (time varies).
I tried different Roms but all do the same.
Also chancing battery doesn’t solve the problem (its firmly placed even laying down on the table it happends(.
I`m running 4.04
even when the phone isn`t warm I do have the problem.
Please how can I solve this

All of this started when you rooted your device?
What ROMs have you flashed?
Try JB leak, if you still have problems there you could be talking hardware.

No the Phone was rooted a while de ago.
I was ussing CM 10

Try JB 4.1.2

I was experiencing random shutdowns myself on 4.0.4, it did not matter which version (Orange Branded or LQ5) so I flashed the 4.1.2 Spanish version of JB and now the phone is a lot more stable. No reboots.

you need to check in CM10 thread whether any other user faced similar issue.
check is there any app which is eating the battery if so uninstall and check. there are many threads available on battery issue feel free to search

Ive had the same problem with a S2 on 4.0.4. When wifi was turned on, the phone would randomly lock up. While it appeared that it was shutdown it was still draining battery but didn't respond to any button except when holding the power button for a prolonged time to restart the device.
However since Ive been running the the OTA JB update for around a week now the problem seems to be gone. Are there more people who had this particular problem and had it fixed with the JB update?

Flashing firmware always helps.
Factory Reset is also helpful (4.0.4's brick bug present, so read before you wipe).
@op either factory reset or go stockland.

[Q] Galaxy S II doesnt shut down (gets stuck while shutting down,not rebooting)

Hi everyone,
first of all I did search forum, but havent find answer nor related thread, if I have missed it please sorry about it.
Got my SGS2 about 6-7 months ago. No issues, everything perfect. Got updated to 2.3.4 with KIES (not really fan of experimenting with phone that have price of above average monthly salary in Serbia).
Rooted device with ZergRush exploit since I wanted as close to mint backup in case I have to send it to service(dont ask, service here is pain in the butt), purchased Mobile Odin Pro (cheers to that Chainfire) and flashed Hellcat's kernel for 2.3.4 from Mobile Odin.
Everything was cool, CWM, made EFS backup with his tool too, and so on...
However, about 2 moths ago, I started experiencing random restarts of the phone. Did search, found out that it happens and actually dealt with it.
Now, recently, i switched off my phone in the evening (was on 20% and didnt wanted to leave it on charger, and didnt want it to die on me during night), and in the morning I havent been able to turn it on. Freaked out badly, only to realize that its battery was empty. Which was odd because I DID turned it off.
About few days ago, i switched the phone, and it went to full shut down, however managed to get stucked somewhere in process (LED's are on, did vibrate i think) but never shuts down itself.
After some time, when I picked it up since I saw LED's on, i realized that its very hot and that I cant switch it back on (presumably because it never got shuts down) and had to remove battery so that I can switch it back on. When I did, i found out that battery was about 15% drained in that 10 mins, and I dont know what he was computing while shutting down, but it burned the sh*t out of itself.
Tonight it did that again so I decided to ask first before I do factory reset/wipe everything (maybe update to ICS too).
So, any idea, suggestion what to do is more than appreciated.
Cheers
Polite bump?
What is the actual problem .

Well assuming you have read original post, why the hell that happen, does it happen to anyone else, and how to avoid it?
this may help
http://forum.xda-developers.com/showthread.php?t=1108499
Well, as I said, its not bootloop.
As I said, I shut down the phone, it starts shutting down, turn on leds, vibrate and stays turned on. After that battery drains quickly, and phone gets very hot.
When I get battery out, and back in it boots up without problems.
And I dont have any cooked rom, just Hellcats kernel for 2.3.4 stock rom.
you problem
Hi there,
Here's the best way to resolve this issue you have to re-flash a fresh new rom, meaning a full installation of the android os and here is how to do it,
First search google and download ODIN to ur computer or Pc.
Next search again google and type the following ( Sammobile.com ) and register and after that type the model number of your phone for example (i9100) in the site search bar and download rom that u need and thats it this should solve ur problem
Note : be sure to have 100% battery charged before doing the above and after installing ur new rom do a full wipe and enjoy,
I hope this was helpful,
Regards,
iMatrix
Yeah, thats probably that I will end up doing, luckily i have bought Titanium Backup so that I can backup all apps that I have and restore them after wiping everything.
I was wondering that somebody have any idea what might be going on.
Thanks for suggestions everyone.
before that try wiping cache and dalvik cache

This seems to happen quite a bit on gb roms.. definetely time to upgrade to ICS
Actually from what I have read about ICS 4.03, Im actually glad I didnt.
Releasing it in that state(e.g. battery issues again, 3rd party sms programs sends sms twice...) is bad for both G and Samsung imho...

[Q] Xperia S shutsdown randomly [Help Required]

My XPS shutdowns randomly after flashing to ICS. I had also rooted my phone with Locked bootloader But due to the problem faced by me i re-flashed with the stock ICS firmware but my phone still shutdowns randomly....
While shutting down It displays Android System and a dialog box which says shutting down please help......
To be precise:
My phone vibrates and turns off. In this days i realized that before vibrates it shows "Android System" and "Shutting down" dialog . that is not cause of battery low. it happened with 70%, 100% battery as well.
that is a 'problem' i've had since i got my xperia arc 2, 3 or 4 times a month it crashes and reboots. i never found out what the problem is/was. i was always rooted.

Hi Rian18,
Kindly do a repair of the firmware u can get it in the pc companion when u connect ur phone to the pc u have an option for repairing.
Maybe this will help. Let us know
My GB firmware used to crash every 2 days or so, forcing a reboot as if battery was removed. It also existed on custom roms. Now after 1 month of ICS usage, I never ever crashed, never had a FC in any app except one time with Facebook app, which is crap
guys i tried repairing the firmware and after repairing 7 days later the problem has started once again ....
So i decided to flash back to GB but after flashing i noticed that even while charging the phone android battery status says Discharging.....
Please help ......

[Q] I'm afreid I might lose my phone.

Hi, thanks for caring.I have tried to solve these problems my self but I coulden't. I have two problems, but I want to tell you what happend before so you know the soure of the problems. A while ago I was srufing the net and I found a stock version of ICS for my regon. I installed it and rooted it and it was fine every thing is working no issue. after five month -now- I installed root browser lite and did a search then left my phone on the table. when I got back the phone was heated I close the app and tried to cool it down with my hands after a minute or so the screen shows horizontal lines on the half top of the screen for less then a second and went off. I pulled the battey and waited for a while then trun it on it work for a minute and a agine horizontal and off. I stard the phone in in CWM and restored my back up. It worked fine but I felt it need to wipe data and factory reset. Here is my problems
1. After useing the phone for more then 10 minute or more it gose off and when I tune it on it back to nornal.
2. The battery is weired, if i let my phone with out use it's fine but when I turn it off and turn it on agine the battey is 10 or less -not always-
( sometime when my phone is 0% percent I plug it on charger and it show thired of the battery is green.)
THESE PROBLEMS APPER EVEN THOUGH I INSTALL THE ROM AGINE WITHOUT THE ROOT.
Thanks for your patient I know it is long but I tried to include everything.

If it's not the battery, it's the kernel.
Tell us more about your device's info (model, rom, kernel, etcetera).

You are good, charge the battery till 100%. Flash siyah's kernel and see how it goes.
You can flash siyah with Mobile Odin, no pro version required.
"OMG!!! Just realized I've got an SII Plus! oh...wait...I've got more Internal Space, nevermind, still got an SII."
The kernel is stock and it was fine before.
any way I found Siyah kernel S2-v5.0.1 should I go for that or there is a specific one you recommend?
Thanks you helped me a lot.
I installed Siyah kernel S2-5.0.1 and the problems are still there. I just tested my phone to see if it's work. I opned a game and play for 8 or 9 minute battery was 62% then my phone gose off. I tried to turn it on but I couldn't I plug it in charger and turn it on battery 33%. what is wrong?
someone please help me!

I think your right. thanks for your help. you people can close this subject.
I HAVE FOUND THE SOURCE OF THE PROBLEM IT WAS THE ROM.
I don't know what wrong with it. Any way I reinstall the stock kernel and flashed Jelly Bean 4.1.2 (Spain) and everything is GREAT. I'm so happy; I solved it!​
Never seen that coming.
Glad you pulled it off

[Q] Galaxy s3 screen stuck on black screen when idle

Hi there,
i've searched the net for help and didn't find anything similar.
my girlfriend and I both using galaxy S3 9300 4.1.2 bought in June.
In the last few week both of us suddenly saw that the phone turns off while it idle.
In most of the cases the solution was turn it back on, but sometimes it didn't help and we had to take the battery off and back on.
today I noticed for the first time that the phone doesn't really off- since the notification led still flashes.
I'm using apex launcher she use TW.
any idea anyone?
I will be grateful,
Thanks
Or
edit:
both phone are stock rom
mine with the UK Rom
Her with the Indian Rom
both 4.1.2 virsion.
I am having the same problems since last week. Sometimes it also freezes in applications. The GUI thread is then still running because I can see animations from loading dialogs and the wifi indicator also blinks. When this freeze occurs, the device won't react on button presses (except very long press on power button to reboot). Also the device is not going into standby mode (screen off) after 30 seconds.
Maybe this is a side effect of the last update? I am running build version JZO54K.I9300XXELLA (Dutch intl version).
Edit: when it's stuck also the battery is drained very fast.
you might be right and maybe there is a connection between last update and all that bugs suddenly appears.
I update through odin to the newest firmware:
I9300XXEMB1 I9300OXAEMB1 I9300XXMB1 BTU
anyone have a clue?
Data wipe would be first start point really

No idea to be honest, are they both stock phones? Rooted? Could even be something inane like a recent app update that isn't working properly, could be almost anything

both unrooted, both running stock rom.
anyway if so, i guess you wont recommend to back all my app, right?
I would back then up, system data is most likely the cause, so my advice would be just restore app data only where necessary and important

Samsung S3 xxEMC2 and xxEMG4 lag/freeze problem, not insane chip f07

i looked on here for tips on how to fix my lag problem
http://forum.xda-developers.com/show...php?p=50499120
I dont have the insane chip, u have fw7, bought samsung s3 on may 2013, manufacture date dec 2012. updated the rom 3 times from what i think originally was EMB1-EMB3-EMB5 and now EMC2 (supposedly an excellent stable rom with excellent battery life)
since monday I have been having a lag/freeze problem where the phone will become unsusable for about 5 secs, then if i start typing again, it''l freeze again.
can anyone shed light as to what has happened?
I tried the dummy file generator method, it didn't crash or freeze once when producing 5-6gb of data. it freezes after a few hours use and the only way to get it to work again is to either update an app or remove an app. very strange.
could it be a corrupted chip?
i've just updated to xxEMG4 (dont know why, i downloaded another yesterday but it failed to install so had to download again).
now i've tried it with the xxEMG4 and it still has the same problem, i'm trying to remove apps one by one to see if that improves the situation.
how can i test if my chip is damaged or in bad condition without rooting? is there any apps i can use? i've already tried the brickbug app but i am not rooted so unable to do the memory test
Don't post multiple threads on the exact same subject.

I've been experiencing the same problem lately and think I might found a solution: it seems that, at least in my case, the problem is with the battery.
I switched batteries with a friend and the freezes stopped. The strange part is that my friend doesn't have freezes either.
I really don't know why the freezes happened or why changing the battery fixed it (or why my friend doesn't have the problem when using my battery).
So, try changing the battery if you can and test it. It's been a week with freeze-free for me, maybe it works for you too.
can anyone shed light on what is happening please?
a further update, i removed bbm app from it and tried to recreate the lag and freezing problems and it didn't so i was relieved that it was an app problem all along.. however i was experiencing battery drain problems which i couldnt figure out so i updated to the latest 4.3 and used that for a month. no lag or freeze problems at all.. the only issue is that 4.3 drained my battery quicker than on 4.1.2 as the lowest brightness wasn't as low as on 4.1.2. so i took the plunge and used odin and reflashed a fresh xxemg4 to my s3 on friday. i did a factory reset as settings kept closing and failing then initially when i started using an app it froze for a few secs then was ok so i thought nothing of it.. spoke too soon. i had the newest bbm on 4.3 and for a month did not experience any freezing, but then today it's freezing again!! i'm on 4.1.2 xxemg4 bear in mind.. i immediately removed bbm as that's what cured it originally, but the lagging/freezing is still there and comes abruptly like when i was using 3g, when i switch on wifi it goes away but am unable to recreate the problem,
is it likely that it's a hardware problem with the chip? remember for a whole month while i used 4.3. i had no freeze lag problem whatsoever (i dont want to use 4.3 by the way so that's not a solution) so does that rule out it being a hardware issue and must be software?
i really want to avoid taking it in to a service centre as all they'll do is flash to the latest rom which is 4.3. (which i have already done) and the removing bbm didn't work unfortunately so im stuck now as to what is causing this freezing/lagging??
is there anyway to diagnose it?

so i've tried it for 2 days now and the lag and freeze keeps coming back and the only thing which stops it is if i install another app and it seems to reset for a couple days.. could it be to do with the sudden wake up opening the device?
i dont have the insane chip and it never freezes or lags in 4.3. (but i dont want to use that cos it has bigger battery drain than 4.1.2) is this definitely a hardware issue but if i go to the store they'll just flash it to the latest firmware (4.3.) which i dont want AND it wont freeze lag anymore.. but that still doesn't resolve the underlying issue that it may be a hardware problem with the chip? how would i get them to replace the chip if i cant show them the issue in 4.3.??
can someone help me please???

ok i've diagnosed it down to the fact one of the cores seems to go offline during the freezing lagging and usually after i wake it up from sleep.
i use os moniter which tells me the info about the device.. it's a quad core phone international model and has the cores listed 0, 1, 2, 3.
i've noticed that when it lags and freezes cores 1 and 2 go to 'offline' with a '?' next to the info as oppose to 100000 or 4000000 etc
does anyone have any idea what is happening to my handset?
is it really a hardware issue? as i mentioend before when i used 4.3. i have no lag issues whatsoever at least i think i dont but if there is an underlying hardware issue it'll be hard for me to get this fixed. it seems the firmware just smoothes over the problems rather than fixes it.
