Stuck at redsn0w 0.9.6b5 - Waiting for reboot

[bu2cow1]

I've update iphone 3gs using itune to os 4.2.1 yesterday. Use redsn0w 0.9.6b5 to install cydia and update to ipad baseband 06.15.00. Process smooth until Waiting for reboot part it stuck for hours. Tried many times but still the same result. Help please...

What do you want to do now, you want to go back to 4.1 (untethered jailbreak)or you want to stay at 4.2.1 (tethered jailbreak for new bootrom , untethered for old bootrom)
