Thanks again LandShark. That link got me started down the road to recovery. I had a few issues along the way that I figured others might run into so I thought I'd share a couple more links.
After my initial EB01 (SC2.2nv) update via Odin, it turned out that my CWM was still stuck on green. Tried flashing in jt's new red CWM and still had green. For anyone who has this issue (and there were a few here and there) this worked for me:
Delete update.zip in sdcard root as well as recovery-update.zip in clockworkmod dir in sdcard (if you have it). Download the tar file from jt's post
here and load via Odin. After reboot, make a copy of the new update.zip file in sdcard root and place in clockworkmod dir. Rename this copy to recovery-update.zip. (It seems to have allowed Rom Manager to install using red CWM for me but some reported intermittent success with this.)
For anyone having issues with any particular component of the EB01 jump (or who have upgraded non-voodoo and now want voodoo) here is a great step-by-step guide for a variety of EB01 install components from root to kernel to rom/mod installs:
[EB01 WALKTHROUGHS] Rooting, Clockwork, Voodoo, Stock and Custom ROM, Battery, etc - xda-developers
If you are switching to Voodoo, don't forget to enable voodoo lagfix after the flash. (I was feeling pretty stupid when I finally remembered this step after the 3rd frustrating try)
A couple other helpful things:
This worked amazingly for battery issues
The Nuance package in the OP
here fixed my BT voice dialing issues
Sorry for the novel-length post. Much of this was elsewhere in this thread but it's a big thread. Thanks everyone! EB01/SC2.4 Voodoo is a DREAM now!
