urgent help required : crushed incredible topic

hi everyone,
i am having a really bad day.

I had incredible s stock 4.0.4 installed, unlocked, s-on, hboot 2.002

I've tried to download the latest 4.4.2 rom i found in the forum, the device showed the update is completed, then the device restarted and froze on HTC screen.

I've tried to install other roms and it didn't work as well, moreover, the device can not be detected by pc without a reason.

I've cleared all caches by the way.. any one can help !
