I tried booting it into recovery and download mode and nothing the phone just would not come on. Any help would be much appreciated. I posted this in the Q&A thread but i just thought that if it had it's own it may get more attention.
try pulling out battery for 30 minute and get it back in..then hold the power button at least 8 second..if that not help,try holding power button longer until the boot come on
if nothing came on,maybe the power button is broken
