Hi
I'm having a samsung galaxy s2 gt-i9100 and it's out of warranty. My problem is that it shuts down whenever it is not charging. It is perfectly ok when it is charging but shuts down when it is removed. When it is unplugged it will stay on longer if I turn the power saving mode on but when I turn the data connection on or when I try to call someone, it shows there is no network.The phone turns off if I put in a sim card and an SD card simultaneously, so I'm not using the SD card slot now.
Not a software problem because everything is alright when it's plugged in. I tried changing the kernel, rom but to no use.
Can anyone help me fix my phone. Any help is really appreciated.. Thanks in advance.. :good:
Probably a short somewhere & probably caused by moisture. That's the nature of it, damage occurs very slowly/over a long period of time & there isn't a lot you can do about it.
Start with the obvious/cheap stuff first; clean battery contacts with isopropyl alcohol, then replace battery, then replace USB board - KeithRoss39 has a guide to enable you to do this yourself easily/quickly/cheaply (~US$10).
That's about all you can do easily yourself, from there you'd be looking at replacing the motherboard, but unless you already have the experience with electronics like this, you're going to be paying someone else to do that.
Even though it's more than likely not a software issue, do a completely clean install of stock anyway, because it costs you nothing.

I know it is obvious but - How old is your battery? Have you tried different battery? I would start with this...

hello...i hope that someone can help me....when i try to turn off the device,it shut down and after few seconds reboot?why?
also simetime the phone don't turn on and on screen i see a green battery with a thermo....someon can help me?
Did you find the answer to this? i am sending my SGS2 back for replacement. i have the same errors plus the following.
Phone selects speaker rather than earpiece as default for incoming/outgoing calls
Phone on ocasions randomly starts Kies and Voice commands even if there is no physical contact with the phone
sometimes the phone defaults back to a launcher i have never seen before (it is not touchwiz) and i have no idea how to launch it without it doing it automatically.
The faults you mentioned can be bypassed with a battery pull but they are annoying, I didn't have these problems until i upgraded my firmware through Kies to KE7.
I have an O2 branded device.

Exactly the same to me
How do you flash congnition? just over the stock rom with odin?
did you flash modem?
Absolutely same here, since coming from CM7 to VillainRom.
Never had that before.
I´m waiting and watching it and your results!
Thanks for this thread.
That's why I don't root the phone..it works fine.

This has nothing to do with root access.
I cannot believe that any problem related just because you have access to your system.
Back to topic, flashed back to cm but problem persists.
It's getting really bad near to flashing stock and bring it back to change device if someone knows what it is could be helpful.
I also have this problem. I think it has something to do with the usb port.
Because sometimes it just scans for media, or it thinks it is charging. Really weird! Then i just put in the charger and it stops for a while. Turning off will just reboot the device. And removing battery and plugging it back it also just reboots the phone.
I hope it is not hardware related...
I was looking for help for a problem I have but this seems to cover most of the problems I'm having.
Mine has recently started going into a strange mode after shutting it down. I get the battery charging symbol alternating with the "battery overheating" symbol.
The only way to stop it is to remove the battery for at least a couple of hours (if you put it straight back in it automaticly starts up and goes back to flashing the battery warnings) or pressing Power, Vol+ and Home and choosing Reboot.
I have also noticed its very slow to respond to plugging the charger in or out. It doesn't always wake-up and bleep when the charger is put in and it stays showing its charging for some time after the charger has been removed.
I was told that the charger should be removed as soon as charging is compleated but surely overnight is the only time we have available to charge these phones!
Depending on the custom rom or kernel you are using, it might not support off mode charging.
To avoid having a "problem" with charging the phone in off mode, some developers decided to make the phone boot up when the phone is been charged when the phone is off.
Going back to an official stock ROM fixes this problem.

As for Cyanogen, since built 23, you can charge the phone when it is in the "off" state. Please wipe out your userdata partition before flashing. Do not restore from a previous backup.
I fixed my reboot problem (rebooting instead of turning off) by letting the battery drain all the way so it couldn't boot anymore. Tried turning it on to see if it really doesn't go on anymore. After that I plugged in the charger and I got the charging-symbol and it did not turn on so I kept it charging overnight while turned off and in the morning it was finished and turned it on.
I also cleaned the usb-port on the phone with a toothpick. It had alot of dust stuck in it which I couldn't see. After that no more problems...for now. They haven't returned for 2 days now.

What kernel and rom are you using? I have not seen the battery overheating symbol on the sgs2.
No, there is no need to remove the phone from charger, when the phone gets to what is considered full, the battery will stop charging by itself.
Are you using the original samsung charger that came with the phone, or are you using a after market charger? Most of these USB chargers do not send a signal on the data lines. When using these chargers, the phone becomes laggy and unresponsive, there is also a delay to register anything on the touch screen. Stay away from these chargers.
For lithium batteries just charge it whenever you feel like it. Lithium batteries have a few thousand deep charge cycles, meaning if you use up all the power, then charge it,you use 1 deep charge cycle. However, if you use the micro cycles for charging, you can charge the batteries a few million times. Leaving the battery on empty for too long will damage the lithium battery.
Can any one confirm if this is a hardware or software issue as i now have the problem when i try and switch the phone off it will just reboot?
The Same issue occurs in my sgs2
hi everybody,
i just got my sgs2 ten days ago
everything seems good at first
then i realized screen standby lock lag problem, there exist a lag between 1 second to 2.5 seconds.
i ignore that due to it cannot be named as a problem, it seems like a bad characteristic
then yesterday , i have faced with another problem
after i have docked the phone to the original vehicle dock kit,
phone cannot be closed via power button , i hold it 1.5 seconds then chose turn off among list, phone looks like to be turned off then after a little while it just vibrates and reboots. That is phone cannot be turned off, it s somehow turn itself on again.
Whats the reason of this problem ?
In another forum one faced with the same problem said that it turned out to be normal when the battery is erased but the problem is occured again after docking.
micro usb connector
I droped my phone in the water, got it alive again, but with all the error(overheat battery symbol, no stable usb connection, reboot when i power off, 100% charged not going away) replaced the micro usb connector with a new one.
Some problems are gone but i still can't connect to pc (kies, debug etc), poweroff problem still happen sometime.
Conclusion: It is not only the usb part of the phone that are causing this problem.
But I do belive its a hardware problem.
Have you phone maybe got to much to drink too..
usb port???
I've recently been experiencing the same problem
When I turned off my phone it switched on again!
And removing battery and plugging it back it also just reboots the phone.
Sometimes the USB connector and charger are confused
Do solved the problem by changing the USB port?
plz help me
Thank you in advance for helping me
This is definately a hardware issue. Clean the usb connector, failing that it will need replacing

I got a wierd problem. My galaxy S2 refuses to shut down.
When I shut the phone down without a USB cable connected then the phone turns black and the 'menu and 'return' button lights up then the phone vibrates. at this stage before the buttons turns black and the phone was totally shut down. now instead the buttons are still lit after the vibration and then the phone starts up again.
With a USB plugged in after the vibration when shutting down I get to the screen where the battery indicating charging is shown, but as soon i remove the USB cable the phone starts.
I got a youtube clip showing all this and I will update the post as soon the 'audio swap' is done.
The power button is not stuck.
It's not rooted:
Code:
Android version: 2.3.3
I9100XXKE7
2.6.35.7-I9100XWKF3-CL276555 root(at)DELL101 #2
GINGERBREAD.XWKF3
I cleared the cache in 3e recovery. No change.
I fully charged my battery. No change
I drained my battery to 0%. No change
I tried another battery. No change.
What's the deal? Does anyone know how to fix this problem?
I'm asking this in order to avoid sending the phone to service since it most likely will be gone for a couple of days. I will not try stuff involving rooting the phone since I need to have the option of sending it to service without them refusing the phone due to rooting.
/Anders
What's the deal? Does anyone know how to fix this problem?
The deal is as always step one backup your data and via recovery factory reset .
Saves the service centre doing just that and may fix the problem .

Hello,
Factory reset was one of the options I was trying to avoid. However I just performed a format/factory reset. And the problem is still there. When I shut down the phone restarts.
Also to add to the confusion the phone can also enter a state when I'm in the battery charging screen (Not booted phone) when a thermometer with a warning sign is pressent. However, I have waited for hours with the battery unplugged and everything is cold. That warning seams wierd to me and might be the root of all evil. That screen is pressent without a USB cable plugged in and that is also abnormal.
Any other options?
Thank you for helping.
/Anders.
I recorded the problem.
I cant post links in this forum due to:
"to prevent spam to the forums, ALL new users are not permitted to post outside links in their messages. After approximately eight posts, you will be able to post outside links. Thanks for understanding!"
but paste this search string to youtube
"galaxy refuses restart" and it's the top clip
alternatively add "/watch?v=eBB_3qtgj68" after the youtube url.

Have you tried to hold down the Power button for 8 seconds? OR a battery pull for 10 minutes?
Regards.
yeah you should try and pull out the battery...
i had the same problem after I used the JIG on my phone.. it refused to shutdown, and kept rebooting it on each try to shutdown..
i pulled out the battery for awhile, and plugged it in and out to the charger..and it worked.
if it's still nagging you, try flashing a new kernel
Yes I tried pulling the battery and also used a battery from another S2 without any changes in the behaviour.
They talk about this problem at androidforums
androidforums.com/samsung-galaxy-s2/377331-spurious-battery-temperature-warning.html
Seams like there is no known fix for this problem yet.
I turned in the phone to the local service center today. We'll see what they say.

Maybe your power button is faulty or stuck. Do you have a case? Is it somehow holding the button down after you release it?
Sent from my GT-I9100 using XDA
Generally this is caused by a dirty or faulty USB port. Shorts on specific pins with specific resistances will cause different behaviors.
Try cleaning the port with a dry clean toothbrush. If that doesn't work, take out the battery, and try cleaning the USB port with a q-tip and a small amount of rubbing alcohol. Then let it dry before putting the battery back in.

I've already tried it and no luck. The technician told me that it is the USB Port problem sometimes also because of overcharging the phone. The USB Port can be fixed immediately but the problem is my SGS2 is a Korean S2. They told me that the port is different from the one's that they have here in the Philippines. Is it true?

Even i used to have these problems. Phone shows charging or usb cable connected for no reason out of the blue. Device wont simply shut down and would start up again.
What i did was perform a hard reset. Pull the battery out first and clean the usb port a lil bit. After some time it vanished

Until now, it's not happening to your S2 again? How did you clean the USB Port again?
Well nothin much...i just took a little cotton and cleaned whatever i can. And then i kept the phone off for about a day or two. And when i switched it back on voila the issue had disappeared
The only problem am facing now is the home button issue taking me to voice command. But then again i froze it with titanium backup. No issues after that

And yeah...been 8 months since i last encountered that problem. Another thing is i used to Yank the device out from the usb/charger cable when plugged in. Now i carefully remove it without much force. Maybe that helped too. Just saying

Hi
I just bought a new SGS2 and it was working fine, until i turned it off...I tried switching it back on immediately and nothing worked, so i removed the battery for a few seconds and still nothing. I left it out for the night and the following morning i put it back in and it came back on
I switched it off recently to put my sim card in (it wasn't picking up the sim card) and now it wont start up again. So now I'm going to leave it for the night.
Is there any way to fix this problem? What if it doesn't start tomorrow? I suppose I can get it replaced...but i have very sensative data on it already (Such as my emails, contact info, credit card info, etc) So i don't particularly want to hand it in to a service center. I just want to get it running to remove all my data and THEN hand it in.
Any thoughts on how to get it working temporarily?
Perhaps the battery is dead, plug in the usb cable and see if it starts charging.
Dead battery charge overnight
Dirty Battery contacts clean .
Try a replacement battery .
See if it will boot connected via the Samsung cable to a PC .
Take it you have ignored rule one and backed up all your data ??
In which case you need to ask the service centre are they able to back up the data .
jje
Well i know the battery is not dead or dirty because the phone has power (It's fully charged since the last time I charged it which is just before i turned it off and it wouldn't turn back on again).
The phone acts like it's completely hard bricked....yet i haven't done ANYTHING to it, all i've done is start it up and install a few Market Apps and that's all
I've plugged it into my Computer, and my PC makes a noise when it's plugged in and when i hold the power button it makes a noise...
It refuses to boot in Recovery mode or Download mode...
Thanks for the replies, still stuck tonight!
Hello,
My SGS II I9100G won't turn ON. I didn't do anything, just leave it on (idle), after back to work, my phone is completely dead. At 1st, I thought the battery is dead, but I charged nothing show-up on screen, plugged into pc, nothing show-up on screen either. I borrow my friend battery, nothing also. It completely won't turn ON.
I didn't flashed into custom rom/kernel, just root it few month ago.
This thing suddenly happen. Help me guys!
But one thing I noticed, whenever I put the battery, few minutes later, I can barely feel hot at the back of the cover..
Additional info:
1) ODIN, KIES not detect my phone!
2) I tried log into download mode, nothing happen!
3) Pull the battery and put back on, nothing happen!
4) Plug the usb & combo download mode, put back the battery = nothing happen also
Return to service center. Borked. And hope they don't discover/check that you rooted it & make you pay for the repair/replacement.
really? someone pls help me

The only other possible thing you can try is a different battery... but sounds like you already tried that... so you'll have to take MistahBungle's advice; if the phone doesn't power on, there's really nothing anyone here can do to help you. What kind of miracle are you expecting???
Miracles post 500 dollars
otherwise clean battery connections .
Unless you can get to download mode their is nothing else that you can do except JTag machine/service centre .
Am i reading number four as you have tried usb recovery jig ??

Hello guys,
I have a problem here that has been bugging me for months
my phone (p8lite ALE21) fell in water for a couple of seconds but after the incident everything appeared to work except when my phone is Idle or I lock the screen and not using it after about 10 secs the phone shuts down for no reason and I have to keep on pressing on the power button for a few seconds to restart, but If I lock it while charging or playing music (anything that doesn't let the phone become idle) it doesn't turn off and works fine.
Confused if it's hardware or software issue but I searched a lot about it tried million different things nothing worked
One thing to notice that my SD card slot doesn't read anymore SD cards ( the cards work fine with other phones )
don't know if it's part of the problem or I have to change my battery?
any suggestions please I would like to hear it
P.S. I don't want to change the battery nor the SD card slot unless I'm sure it's the problem
Thanks

From the info you provided, I believe it is a hardware issue, a faulty circuit, since the phone is unable to remain on until some interrupt is provided, I recommend that you show it to some Phone repair center.
