I think its an issue with the drivers and my PC.
I'm on hboot 1.5 and its unlocked. I have windows 8 (but also tried this on my win 7 pc) ..I downloaded HTC sync and uninstalled. I have SDK tools with all the updates.
I go into fastboot on the phone, it shows fastboot USB and then my PC recognizes the phone but tells me there's a problem with the driver. I manually select an android ADB driver I have (I have win 8 in the mode that does accept unsigned drivers), it says everything is ok. But then a few seconds later the phone 'disconnects' and doesnt show 'fastboot usb' any more and says there was a problem.
Anyone have a driver I should try or any other suggestions?
