Please Help!!! Won't Boot after flashing Custom Rom

view story

http://forum.xda-developers.com – Hi, I have an old Evo 3D purchased from eBay (shipped from Singapore). The phone is now out of the warranty, so i decided to install a custom ROM. What happened was that the phone was running on stock ICS. Then I unlocked it through htcdev. S-on, HBOOT 1.53.0007 Installed 4ext recovery, works fine. v RC5 (seems a bit too old, but it's the only one worked) Then I flash a Jelly Bean 3D rom through recovery, successed, but when the phone is rebooted, it stuck on the animation (the animation is working just fine, but it just doesn't go anywhere, it doesnt reboot itself either) (HowTos)
