Evo 3d got stuck on HTC logo white screen

Last time i was able to root the device and get s-off by wire trick.
I tried various roms, faced issues flashing them but got things done with help from XDA threads.
Got my device restored back to stock many time and then get it rooted back again.

This time i m not quite sure where i m going rom.
the boot loader is unlocked, installed custom recovery 4ext.
flashed a rom and it all went bad. cannot get the device back to work.
Cannot flash boot.img file error says
"(bootloader) signature checking...
FAILED (remote: signature verify fail)"

cannot restore back to stock fails saying
"mainversion is older"

Here are the device details
mainver: 2.89.651.2
cid HTC__001

*** UNLOCKED ***
SHOOTER_U PVT SHIP S-ON RL
HBOOT-1.53.0007
