I have a CDMA Sprint HTC Hero running 2.27.651.6 If I have read the FAQ/Stickies/Walkthroughs correctly the first step in rooting my phone is to downgrade it to 2.27.651.5. I downloaded and attempted to run "RUU_Hero_C_Sprint_2.27.651.5_R_signed_release" however it doesn't complete. The program is "Waiting for Bootloader" for about 80 seconds and then fails with "ERROR : USB CONNECTION ERROR". I am able to hear the Win7 sound effect of my device being disconnected when the program says "Rebooting Device" and I hear another sound effect right after it, like it is trying to reconnect the phone to my PC but the sound is different. I think something may be wrong when the device attempts to reconnect to the PC. At this point my phone is connected to the PC via USB and the phone is now stalled on the black screen with white "HTC" logo. If I unplug the USB cord at this point I get the white screen with skateboarding Androids at the bottom (which I assume is the bootloader). The following text is at the top of the screen: At this point I need to remove the battery to restart the phone. I've started this downgrade process with connection type set to "Charge Only" and "Disk Drive" with the same result. Any help via this forum or AIM (zdkirkp) would be greatly appreciated.
