Okay...I used Z4Mod and went with a permanent root (seemed to be successful)...I grabbed the free version of ROM manager from the mkt place...I then flashed Clockwork Recovery in ROM Mgr...Finally, I selected "Install ROM from SD Card." A prompt showed up and I selected "Backup Existing ROM" and "Wipe Data and Cache." After checking OK, it rebooted and froze on the HTC screen for 15+ minutes two times. I have two zip files on my sd card: "update-cm-6.1.0-RC1-Heroc-signed.zip" and "gapps-mdpi-20101213-signed.zip" This is as far as I could get...thanks!
Instead of installing from ROM Manager, select the option to Reboot Into Recovery.
From there, select Wipe Data/Factory Reset, then select Wipe Cache Partition, then go into Advanced and select Wipe Dalvich Cache.
Once those steps are complete, go back to the main menu and select Install zip from SD Card, then select Choose zip from SD Card. Find the CM zip and select it.
Once it completes, select Install zip from SD card again, find the gapps zip and select it.
Go back to the main menu again, and select Reboot now.
