I have the same pb. After flashing gingerbread with odin (using one package), the screen stay black after the flash reboot. i can see green pixel on the screen. The sound works, i heard the boot sound but i can't see the animation. now i'm flashing back to arkas roms.
WillingMagic reckons 2.6.35 is incompatible with some phone .He is going to create a 2.6.32 Gingerbread port
try reflashing it with odin with 2.3.4 or 2.3.6 on odin but instead of flasing as one package, don tick one package,load ro m file on pda...
