Ok, I have an Evo, software 3.70.651.1, Android 2.2, Baseband 2.15.00.11.19, and hardware version 0003. When the Unrevoked version 3.3 came out I used it to root my phone, no problem. I used the stock ROM for about a day, then flashed Fresh 3.5 using ROM Manager and clockworkmod, again no issues. Then I decided to try Myn's Warm Rom, and the problems started. If I try to flash any ROM, it aborts. Then I re-installed ROM Manager and changed the recovery to AMON RA 1.8. Went through the wiping process three times, and then tried to flash, and still got errors. When I'm using Amon RA, it freezes on the splash screen. Then I have to re-install the stock PC36IMG file, and start from the beginning. I am able to restore my Fresh 3.5 ROM I saved using ROM Manager, but I can't use any others. If you have any ideas of what I can do, other than stick with the Fresh 3.5 I had working, let me know.
