Samsung Galaxy S3 will not turn on

[GSDer]

Welcome to the forums!

PS: Could the thing with the stuck power button be an issue? After putting the battery back the white screen appears automatically without pressing any button

That sounds like a typical symptom of a stuck Power button/switch. You should pursue that fix until the phone no longer turns itself on when you insert the battery; then come back and we'll look at any booting issue.

I need help.

I recently downloaded and installed APK installer and Flash for android and the phone was working fine afterwards, but then when I used my assistive light on my phone the phone shut off!

Now its stuck at the SAMSUNG screen and won't boot up at all, every time I try to pop in the battery the phone boots for 10 seconds and then shuts off and it does this every time I pop in and out the battery. I tried going into recovery and download mode and the screen still shuts off after 10 seconds. can someone tell me what the issue is and how can I solve it? please, I really need this phone operational soon.

MODEL: Samsung Galaxy S3 SPH-L710

As with the previous poster, it sounds like you're experiencing the 'stuck Power button' syndrome. You can try following the instructions in the YouTube video (http://youtu.be/KXSbBG4NV-w), or you can open up the device to try to unstick it. It may actually be the Power switch on the mainboard - there's no way to tell until you get the Power button (the plastic piece that you press on) out of the picture.
