Don't worry, I experienced same problem before, but with other ROM. It can be fix.
Just use Odin to flash Lighting ROM. If your pc can't detect your phone, then use Samsung Kies together
Lighting ROM is good for this job because it won't wipe your data.
After flash to Lighting ROM you can reboot to recovery mode. Then restore backup.
If you like, Lighting ROM then don't need to restore backup. All your data will still remain as before.

phone is totally dead, stuck at yellow triangle ... tried to flash to CheckROM 3.1.1 from CWM (previously was on V2.0)
Selected the fw 3.1.1 which was on the phone memory, rebooted and yellow triangle. Tried the power+home+vol up cannot get into recovery. Tried flashing siyah again using odin, still no luck.
I can get into download mode (power+Vol down+home).
To get into CWM, no way.
