rooted EVO, but cant flash most roms =(

[blazin-asian]

so i went to install the newest infected rom with sense 3.0 and was very excited about it. repartitioned my card with RA, wiped, and installed and got boot loops upon sense startup. tried a dozen combinations of superwiping, cache/dalvik wipe, double flashing, fix uid, etc but no luck.

i then decided to try the BOS kingdom rom and get the same problem, boot loops as soon as sense loads. maybe i wasnt destined to install sense 3.0 roms.

ok, so i decide to try KingsROM shift4g blakk rom. its a sense 2.x rom so it should be ok, right? nope! boot loops as soon as sense loads up.

at this point, i suspect its my sd card. i use a 1gb without any repartitioning and try KingsROM again. still same problem. the only roms i can actually get flashed are the latest Fresh and Warm 2.2.

i think the problem may be my phone and not the sd card or rom.

details:
003 with nova panel, S-OFF with unrevoked forever
HBOOT 2.10.0001
RADIO 2.15.00.11.19

i have tried RA 2.3 and CW 2.5.0.7 (the newer version doesnt support some sort of scripting so i use an older version). i also superwipe 2-3x before EVERY flash and sometimes wipe cache/dalvik AFTER a flash.

does anyone have any suggestions on what i should do or try? any input is appreciated and i thank you all in advance.

EDIT: someone suggested a different kernel like netarchy. i tried 2 non SBC kernels with same problem.
