Galaxy S3 wont boot

[RadiantRob]

So I had my Galaxy S3 since it came out. A few months ago I noticed it shut off and wouldn't turn back on. (it would vibrate when the battery was inserted, goto samsung boot screen and never go anywhere from there) I noticed this site and a lot of others having the same problem so I began to trouble shoot.

I cleared my cache by getting into the boot screen and that seemed to fix my problem.

Now about 2-3 months later it started doing the same thing! This time clearing the cache did nothing, heck sometimes I can't even get a chance to clear the cache without it restarting on me again. Sometimes (if I'm lucky) i'll get it to boot up and it will go to home screen without a problem. Little to know it shuts off without warning and I'm stuck at the beginning.

This phone has never been rooted. Please help! I'm using a mytouch 4g now and this thing is slow as molasses! Do I have any chance to recover my s3 or is it sudden death syndrome?

Also I had alot of pictures/videos on the internal hard drive of this phone, is there anyway to retrieve those since my phone can't even boot up?

Welcome to Android Central! Have you tried a different battery? Take out your battery and try spinning it on a flat surface--if it spins freely, the battery is likely dead or dying (suggested by the bulge in the middle).

I havn't checked the battery, but I've never had any issues with the battery before (no signs of extreme battery loss) but I will give this a try when I get home from work!

Batteries can suddenly go belly up with little warning, so it wouldn't be out of the question.

This is a topic to consider when the phone is still working - if you can't boot the phone into Safe mode or normal mode there's not really anything you can do.

A JTAG service (ex. http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-iii-jtag-brick-repair/) might be able to recover the phone to a working state - you'd have to contact them to describe your problem and see if data recovery is possible.

Otherwise it's insurance replacement time, or Samsung repair time. Sorry.
