I have a samsung galaxy s3 with some stuff stored on the phone I want to get back. Some data wasn't on the card. When this happened the first time I put my cellphone down and next time I checked it automatically turned off. When I noticed this I tired to turn on my phone again and it booted perfectly. New minutes later it turned off on me again. As time went on the phone started to die faster and faster to the point now it shows the galaxy picture on boot up then instantly turns off. I tried switching out batteries but I ran into the same issue. My two guesses is it has something to do with boot loop or the connector on the phone and the battery went bad. But if it was a boot loop it wouldnt of booted up correctly first and second times. Any clue? If its possible I would like to order the part I need and repair the phone myself. Thanks for your time.

 

I'll definitely try that. Freezer or refrigerator? And I'm on my new one right now I got it off eBay. Thanks!

 

Thanks freezer or refrig?

 

It automatically turns on but same thing. Hits the blue loading scree nand then disappears and turns back off after a few seconds but it does not try to reboot itself so I dont believe its a boot loop problem

By holding the power button my phone does nothing. When I take out the battery and put it back in then it tries to boot. But it hits the blue loadign screen then turns itself back on (no boot looping) just turns itself back off. But the power button does nothing.

after messing with it for about an hour it did manage to boot up once all the way. but as soon as it hit the login screen with my passcode it turned back off... :'( it seems like sometimes it gets lucky and boots farther than others.. it cant be the bootloop has to be something inside the phone like the battery connector.

 

I need the data out of it lol

 

I'm pretty sure it's the housing on my phone is loose causing the battery to easily go out.

 

I got it! I got all the data off of it. It was a loose housing on the battery. I messed with it a little and I got it to boot up. Found the best way was to put the phone with the back case off and slam the phone down forcing it to boot up. Don't try to pick it up just let it sit there sometimes it would boot up all the way. Don't try to connect a charger or anything it will force it to turn off. Lightly touch the screen making sure u dont mess with the battery. I transferred everything to my sd card before my battery died! Thankyou!
