I need to SBF a phone to send back to verizon then SBF another phone to update to .340 and install the newest rubix. I've SBF'ed before. but for the life of me can't get RSD 4.7 to see the phone on windows xp or 7. and on my xp machine i can't get 4.8 to install. it keeps giving me an error. I am in boot loader and not recovery. any ideas would be great. thanks.
