Hi folks,

So here's the deal: my Samsung Galaxy S2 suddenly refused to charge and became very hot. I turned it off, took out the battery and it won't accept any new juice.

After I turned it off, it won't even start. So I have a battery that cannot be charged, and a Galaxy S2 that refuses to start. When connected, a battery icon with a triangle is displayed. Any ideas?

Should I try to get a new battery or is there any trick for this? I'd rather not send it away.

Cheers

It's pretty similar to this issue:

This is identical to my problem. To restart your phone. Take the battery out. Plug the phone in, wait a few seconds then put the battery back in. Imediately, press and hold the power button. The usb charging circuit is damaged. It needs a repair but will probably be replaced. A few of us had this problem.

Thanks for your reply! If that's the case, it's the first phone I've ever had since 1998 that has broken down.

I tried the method of starting it that you suggested, but it didn't work. I guess I have to send it back. Even though it's a great phone in other regards, I won't be buying a Samsung again.

Hm, it suddenly decided to start again for some reason and now I can charge the device while it's turned off. But when I try to charge it when it's turned on, it just becomes super hot and loses power instead of gaining it.

Can it be a software issue? It's really weird, since my SGS2 can be charged while it's turned off but not when booted.

Cheers

Hi there i have the same problem with mine too, do you flash any rom in it or kernel?
I guess its a problem with the kernel or rom you have flashed, mine have the same problem, but you can put it charging in the usb cable in the computer and let it stay there for a whyle, then you have to try to boot it up by using the 3 keys (power+home+vol up) it will boot in recovery mode then you ask it to reeboot and install an updated kernel or reflash the rom, while the device is on, do not put it off, because if you do it you will have the same problem to put it on again, but when its on it charges normally.
I have changed mine for a new one but the problem i am sure it was the things i flashed it. I was using another kernel to install and root the device and again put the original stock kernel in the device to get rid of the yellow triangle, but that came up with that problem. I even dowloaded root explorer in order to reset the battery status bin (you have to be rooted to do this) and reboot the phone but with no avail. The other you have to do this is install CWM MANAGER V1.80 MY KERNEL CF-ROOT 4.0 MY ANDROID VERSION 2.3.3 BASEBAND i9100UHKE2 and now note this the stock kernel was the uhke4 but the kernel i put it it is 2.6.35.7-I9100XWKE7-CL215725root@DELL103#2 COMPILATION NUMBER: GINGERBREAD.UHKE4
Note: i dont know if it will work for you, i am using a stock rom from samsung. If you do not flash anything its better to return the device or even you have flashed it buy a usb jig and reset the counter and find for the repair, they have to fix that for you.
I hope that have provided you some help.
best regards

@OP- Go to Service center. Don't waste your time by doing this and that. I am having the same problem, though freak me did some experiment with it. You will get replacement/repaired as it's inside warranty very much.
And don't try any freak method with the new one.

Regards.
