UPDATE 2.0 It was the Fuse un the power board that caused all that trouble. In fact it was a fuse with resistance! So it powered off when it was underpowered! I just removed the fuse and it worked (replaced with a wire)! I hope this will help somebody with the same problem! Louis
OK I FIGURED SOMETHING OUT !!!!! When I push SELECT and VOLUME DOWN on boot it works BUT when I power it off on MAX brightness it doesn't power on anymore !!!! SO if I put the brightness just one step DOWN it WORKS !! Still I would like to know what's causing that problem
Unless you have a backup on google foto's, you will not be able to get something off when it's off. Or if you really want it back you can change the battery (at least if you can find one). Louis
Already tried to push the power and home button at the same time ? It could be a hardware problem.. Already tried changing the battery ? Try with a CHARGED battery maybe it's the charging IC. Let me know how it turned out ! Louis
