one thing ive notice about hard reseting is that even if you press all three, it doesnt always work, it sometimes tends to just turn on

what ive noticed is that its not always a same time press thing

FIRST press the end and send key,

THEN, (while still holding the 2 front keys) press and hold the power and wait

if that doesnt work, like a post above ses, flash a rom

you can download stock roms for the phone on the htc website
