I need help unrooting the HTC Magic, I have tried many things but I can't seem to make it work. I have a Windows7 computer, I plug my HTC magic into the computer and the program HTCsync syncs the phone. As soon as I launch the RUU utility program, it disconnects the HTCsync and I get an USB error message. I also tried changing the capability mode into WindowsXP or Windows Vista but that didn't work too. I also tried using Virtualbox with WindowsXP but the HTCsync does not sync wit the phone.

Suggestions Please...
