sprint 6.1 rom upgrade error 260, please help

[fixxxer2012]

ive seen a few threads but they don't deal with my specific error. my phone is connected via active sync with no problems. the phone screen turns to a rainbow color and it disconnects from active sync. then after a minute i get a error 260 code from the update installer that says the install cannot continue and to check my usb cables. ive tried this 5 times with no luck. i basically have to do a soft reset to get the phone back to normal.

is anyone else having this problem ? i really need some help here guys, id like to install this update.

and yes i have a sprint htc touch in case you wondered. any help would be so appreciated !!!
