Please help, phone stuck

[DroidFan291]

My phone is currently getting stuck at "Samsung" while it is booting. I would greatly appreciate any help in getting it corrected.

Here is how I got to this point.

I have been using superclean 2.4 nonvoodoo.
I decided to upgrade to superclean 2.9.

• Downloaded new rom and moved to phone by usb
• went to ROM manager to backup and install
• noticed a new version of clorkworkmod and updated (I believe this is the start of problems as I read that CWM3 was having issues)
• Attempted a backup and noticed it finished very quickly (I wasn't closely watching)
• Tried to install rom
• Again I didn't watch closely but it finished quickly and the phone hadn't changed
• tried again, watching closely. noticed clockwork wasn't starting at all.
• verified clockwork was installed and made sure permissions were verified in rom manager
• tried again, same deal
• read that the new CWM was having problems so I used Odin to flash a CWM recovery I had from before (red 2.5)
• rebooted and tried ROM manager again
• Rom manager somehow started up an orange CWM 3 but it errored out.
• I flashed 2.5 again
• Booted into CWM 2.5 red and tried to do a back up. The backup froze for about 30 minutes, so I battery pulled
• Phone booted and stuck on samsung

I can get to CWM 2.5
I tried to restore a backup from today and get the error "Checkign MD5 sums... MD5 mismatch!"
Rebooting system from CWM still gets stuck at SAMSUNG

Any thoughts?

Update:
I flashed a different CWM file and was able to complete a back up.
Reboot phone, still stuck on SAMSUNG
Tried to install the superclean 2.9 rom again and was successful.
It took about 20 minutes for the boot to finish, but it looks like it is working now.
