First and foremost, you attempt this at your own risk and I am not responsible for what happens to your device. This saved me from buying a new phone when I had an unidentifiable and persistent black screen/boot loop

Symptoms you are boot looping due to your power button sticking:
1. Black screen with intermittent vibrating
2. Phone restarts during boot animation
3. Unable to enter recovery before phone restarts
4. Unable to enter download mode before restart
5. USB JIG forces phone into download mode and restart occurs
6. Phone turns on when battery is inserted

This fix will only work if the button is STUCK and not defective. Remove back cover and battery. Remove the 6 screws on the back of the phone and gently pry the housing off.

After that, find the power button. Using a small flat head screwdriver gently push the button cover away from the mechanical button and try to press the mechanical button in to see if you can still feel it "click". After that, reassembled and test. Hope it works for you too.

Hey buddy, I want to thank you for your guide.
I followed it every step, but unfortunately I was not able to fix my phone.
It still loops every time I press on the power button.
It might be a hardware failure.

Not sure what else to do.

If this didn't work, get the button replaced. I got mine fixed by mobiletechvideos for 35 plus shipping

my buttons were sticking ( power button and volume down ) to on my phone , it got to the point where the power button was no longer working and my phone was out of warranty. I just decided to take phone apart and disassemble it and then i located the power button and used some " CRC QD Electronic Cleaner " and just sprayed it (using the straw that CRC comes with) directly into the power button (when i say "spray" i mean i pushed the spray button for about 1 second). After spraying it i pressed the button like 20 times, then i sprayed some more and while spraying (spray for 1 second) i was pushing the button about another 20-30 times. I repeated the spray and push cycle about 10 times (which means i probably pressed the power button over 300 times ), I waited about 5 mins to make sure it was "dry" and then i put the battery back in and test it and It seemed to have cleaned it out and now my power button worked. Then i put everything back together.

Note: I tried to spray and press it with the phone with the enclosure/case/body on but the button cover blocks the actual button and i was forced to actually disassemble the case, its not to hard just looks intimidating. whole process took me about 45 mins first time.

Note 2: CRC QD Electronic Cleaner can also be found at most local auto parts stores BE SURE TO GET THAT BRAND as it is non-conductive, i repeat GET THAT EXACT BRAND/MODEL Cleaner, cheaper brands might be conductive despite it saying it is safe or does not dry as fast and who knows what might happen, CRC is a known well brand and has a good rep)

original thread there

...Hey where did that "thanks" button go!!...

I made this account just so I could give my 2 cents here. I was having random reboot problems with my sgs2 and it would vibrate on a black screen after rebooting etc. I took the back casing off by taking out screws and prying off plastic backing and just hit the power button with an air can while pressing the power button and voila, now my phone isnt having the issue anymore. Thought id have to replace the button but it seemed to be working fine so i thought id try the air can first. Thanks everyone for pointing me in the direction of it being the power button, wouldnt have guessed that myself.
