Be more specific, what did you try to get V9 recovery installed and what was the error/problem?Had OTA installed by Sprint tech (unbeknownst to me) when I picked my replacement phone. Followed the directions for reverting to V9 succesfully. Could not get V9 (thunderc) recovery installed. Could not get root with tool or ADB.
This S*cks. Any suggestions?
If you want to root with V9 you can just use z4root from android os.
