I am having problems unrooting my Hero. I downloaded the RUU from geek for me and went through process as instructed. It goes through most of the process alright but ends with this error message: Error : File open error The ROM Update Utility cannot open the requested files or the files are damaged. The RUU cannot continue with the update. Please get a complete RUU package and try again. Right now the phone won't get past the HTC screen, and wont power off without removing the battery.
