Hi guys,

I know there are Threads about S2 shutting down randomly but in my case it's a bit different.
I bought my S2 as a used phone roughly a year ago. I rootet it and installed cyanogenmod 10.sth.

The problems started maybe 3 months ago when the phone just randomly shutted down after screen flickering although the battery was not empty. The guy from ebay told me it's not the stock battery he changed it. Now suddenly the power button is not working anymore so I changed the lock button to the volume down button which worked briefly. So now the phone is running but I can not unlock it because neither my power button nor the 'new' unlock button (volume button) is working. I can however plug the USB cable into the phone which will wake it up.
Next I tried booting into clockwork mode which worked without pressing the power button at all. I only pressed volume up and down. Inside the clockwork menu I could not select anything because the power button is not working.

My problem is I can not see any pattern in this mess. I am thinking about a defect/old battery or permanently active power button or damaged ROM, I have no clue.
Do you guys maybe saw this problem before or is it a combination of several problems?

Best,
Hoernle

Hi. Im currently on prerooted 5.0 without xzdr with unlocked bootloader. I cannot completely shutdown my phone. once it's turned off, it turns on again by itself. It's really annoying as it will stuck in bootloop with the sony logo. I have to force shutdown the phone to turn it off completely. It can be turned on normally after a force shutdown without a bootloop. When it boots normally, the green led light is shown. Could anyone give me some guidelines in fixing this? i have tried to flash back to stock 4.4. then root. xzdr. then upgrade to preroot 5.0 . it would be appreciated if there are some ways to solve this. thank you so much in advance.

Bear in mind I am not extremely tech savy. I just got an S5 when the S6 came out, AT&T, and I don't know if it is just my phone, if I've done something wrong. What I'm trying to figure out is, why when I am in Facebook it will freeze and occasionally close?
