I've never used CWM recovery, so this is confusing to me, but maybe it will help you. I use RZRecovery and would just wipe cache and dalvik cache a couple of times then reflash this rom. Make sure the flash completes 100% and maybe flash it a 2nd time if it sticks the 1st?
Also, this for help with adb + logcat. I'm not sure how that works during flashing, but if it relies on your pre-existing rom's setup, it may be helpful to know that some newer kernels are disabling logging to help speed up the phone. ChevyNo1's kernels, for instance, do not support logcat until you reenable it. You might try flashing a kernel that doesn't disable logging or enable logging before attempting to flash and logcat.
