solved i was flashing a rom, but i guess i didn't do a wipe or something, so now my sprint evo3d won't boot. when i power up, it shows the htc logo and thats all.
i can get into recovery(TWRP) and fastboot just fine, so what do i need to flash/wipe to fix this?
rooted htc method so unlocked with s-on hboot1.50
solution if anyone has the same problem:
reflashed my previous rom then was able to boot. now i am restoring and backing up like i should have
