[Bandaid Fix] Boot looping due to power button

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.
Help!!!!

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

save this for furture use thanks

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)

this trick was the one that worked!:good:

so after giggling and wiggling ... spraying and pushing ... (none of which worked)
I went back to the Nintendo standby .. blow at the port ... go figure ... i guess something got stuck in the USB port kept making my phone reboot lol

Thanks for the help all!!!!

Ugh..any other suggestions?? I can't believer they are considering this ISER damage! This is my third one. First one had powerbutton issue, replacement had a screen issue where it look like water was on the screen... Two months later is one has power button issue.. This is some bs.

OMG!! You just saved my phone (and my wallet!!) Thank You so much!!

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.

Mine was still clicking. Kinda took it upon myself to do this and I also sent mine to Mobile Tech videos. The service he offered was great but a bit confusing

I have two hercules and first one which is about 10 months old started having power button problem(infinite boot loop) in Last November.

At first, I kinda clicked it ^well to let it boot to ics but as soon as I press the power to wake up screen or shut off the screen the phone would restart n go into boot looop.

So I tried not to use the power button at all but it got to a point where it was unusable. So I opened it up and cleaned he inside but it didn't help. So I decided to send it off to mobiltechvideo.

But one day, it just dissapeared completely. I mean I suffered so muh from this yet it is gone and I can't even simulate the bootloop now.

I am thinking its not electrical problem due to chip in the button go bad but rather physical problem.

Perhaps tiny particle or dust getting into ppwer button module causing the boot loop.

After trying many different things, including opening it up, air can, etc. I sent my phone back to T-Mobile. They made me upgrade from stock GB to ICS first though insisting it was a GB issue. New phone works perfect... you shouldn't even need insurance to do this as its a defect not broken by user.

I tried to take it to the T-mobile store and they said since I didnt have insurance nothing could be done. I am so pissed at them since I have been with them for over 8 years and never had any issues with phones. What exactly did you tell them? I tried all the fixes and my phone just does not want to stay on. I even took it to a cell phone repair shop and they were completely useless. Told me that it was a software issue. I am on stock iCS just rooted.

may be the power button is dead
i shipped to mobiletechvideos for 35 plus shipping (found in ebay)
hoop he can fix it by replace a new power button

I had the same problem but on the att version. There was a cable/wire that had a clip on the end that was loose. I just made sure it was well connected and it stopped rebooting. Total cost $0. Really easy fix, no need to send it any where.
