Got the threads confused.. I went into Rom manager yesterday to rename a backup and was prompted for an update available for CWR, 4.0.1.5 I believe..
Booted into it manually, I only use Rom manager for renaming.. made a nandroid, flashed a new kernel, and after a while I noticed the phone was slugglish, haptic wasn't keeping up with keystrokes etc. And when I booted back into recovery it wouldn't. Kept hanging at the HTC screen.
After numerous battery pulls trying to get the ROM to load I got far enough to try and undo the update, no luck, phone froze, couldn't get to recovery through hboot, Rom manager, manually, nothing.. ROM and recovery refused to load.
Ended up pulling the SD and using my card reader to load jcase's 4.0.0.5 version and restore my backup.
I'm hoping team WIN's recovery is 100% soon so I can ditch CWR all together.. someone else is running the newest version without issue so maybe it was a bad download, but given the option I would've rather stuck with 3.0 whatever..
