request delete thread [Q] galaxy s2 won't stay on - Android Q&A, Help & Troubleshooting

Hi guys.kinda need advice. I had this s2 for 2 days, ran beautifully, benchmarks and all, gave it the works. I installed root and installed custom roms, everything went super. I was on Resurrection-remix_ics_V2.1_AOKP-B37-4.0.4 and installed SPB.Mobile.Shell.v3.5.3.Build.9885 and I was out with my daughter. I made some photos (by the way I applied the patch for the camera from resurrection) and at one time I was taking a photo and my phone turned off instantly.
after that i rebooted, it was ok, even the poto tat I made was saved but after a while when I tried to take another photo it turned off again, this time when I tried to reboot got stuck on resurrection logo. I turned it off and tried to flash the rom again on the spot.I must have had about 80% battery. Nothing. it started to turn of as soon as Samsung logo came on. Scince than I flashed about 8 times a few custom roms and 1 original for my country. I got it to turn on (today) but it turns on completely only if I keep it pluged in (comp. or wall socket) and if I try to run demanding applications it turns of. what could it be....a voltage problem of the batt, or cpu wise? I really need help. Thx If any additional info is required I will provide it.

Post this in the SGS2 device thread, you'd get more help there

[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

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...

Phone not working properly, auto off, not able to switch on crashing many time

I am having P500 for a year and tried so many experiments on it, 2 times I got changed my PCB from LG Service but from yesterday I am facing a very different problem.
I was using cynogenmod Android 2.3.7, I notice that my phone is switched off, when I tried to ON it it comes to LG logo screen and switched off again.
After long time my phone booted successfully but unfortunately it switched off again automatically after 3-4 mins. I am unable to do anything on it.
So I finally decided to boot into recovery console and re flashing rom, but I am not able to boot in recovery also it comes into recovery and after 2-3 clicks it will restart, restart and restart again.
I notice that sometimes it automatically comes me to "Emergency mode screen"
I finally decided to Flash it using KDZ updater, I prepare and start flashing using KDZ updater in emergency mode, (Going back to stock ROM).
I flashed it successfully and phone restarted, but the problem is same, phone still having same issue, sometimes it switch off automatically while playing game, and wont be switching on, going to emergency mode etc. I have to pull battery many times to get it on.
It was working fine from last night, I open an application and it crashed again and not switching on, after 20-30 times of pressing button and pulled out and inserted battery 5-10 times it switched on and working since 2hrs.
Phone is working as normal but I don't understand that why it act like this?
Android Version: 2.3.3 (Stock LG ROM)
Built Number: GRI40
Software Version: LG-P500-V20c
Please help if there is any solution, I don't what to move LG service centre, they can't do anything just changing the hole hardware PCB.
Also I am regular visitor of XDA Forum and used it since a year, this is my First Post here, I seems there are lots of problem solved on this board lets see, if anyone can help me.
Try to change the battery with a new one or if you have a friend with an LG P500 phone ask him to give you his battery to see if it's battery fault, if it's so you have to buy a new battery. Also leave everything stock, and no Overclocking.

Yea, it is working fine since yesterday, i also removed some applications and games, let it test for more couple of days.

SGS2 bootloop! Help!

Hi guys! First off, I know this sounds like a common problem, but I've looked through several times and haven't found a solution yet.
I have a SGS2, came as 2.3.3 stock but upgraded a while back to 2.3.5 through Kies. It was working perfectly for as long as I remember.
About a month ago the battery started acting weird going from 80% to 20% in no time, heating up too, I do remember dropping the phone once during this period, but it was nothing (just thought I should include this, also, I usually leave the phone plugged into the charger overnight as I do not have a power source at work (i work outdoors) i probably need a battery replacement)
The screen brightness would sometimes flicker and then POOF! The phone shuts off...At first this would happen at any activity, nothing specific, BUT, I have noticed that it intensifies with the Facebook app.
Anyways, usually plugging the phone back into the charger and powering it up would bring it back online, but not this time. It would get stuck looping the animation of the 'S' at the beginning and no booting up. I have a valid warranty card which I'm guessing will get the phone either fixed or replaced but I need help to try to salvage whatever info I can get my hands on, preferably everything, but my memos are most important to me.
Thanks for the help!

Weird. It shouldn't boot loop. You sure your version is GT-I9100 and not GT-I9100G? Since I'm in Riyadh, the latest version for GB here (Saudi Arabia) was JPKJ2, but that's for GT-I9100, dunno about the G version.

okay so with the help of a friend and this awesome forum, i managed to install cwm, from there i could take a nandroid backup, but i cant mount the phone as a drive or anything to copy the files, and i'm guessing i cant use this backup i just took to restore later because it'll just get me stuck at the same place im at now
i read that i can use unyaffs to extract files from the resultant backup image, so my question is, before i do a wipe, is there any other method through which i could get a backup of my stuff? the things i would very much like to get a copy off are my messages/notes/whatsapp history and pretty much anything really
thanks for the 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

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...?
