Hey dude, I was using the Damage Control ROM, and after 2 months my EVO started to random reboot and stuck in reboot loop. I know you had the same issue.
I've already:
Wiped boot, system, data, cahe, dalvik, batery and reflashed all
Updated PRI, PRL, HBOOT and radio
Flash various kernel from netarchy and stock
Flash mikfroyo and stock ROMs
nothing seem to work.

Can you please, for God's sake tellme what did you do to solve this?

Thanks in advance ^^
