so i have looked every where, and from what i have been able to figure out is that this error is due to either an SD card not willing to become a goldcard or the RUU i downloaded is incorrect. i downloaded the RUU from bak2basiks page which is what a few of my friends downloaded and worked for them. and i tried to dl it from xda site but that link is dead. so before shooting myself in the face my friend recommended that i try the fountain of knowledge that is androidforums.com I have the HTC Hero, gsm, on the Telus network. im hoping someone has had the same problem and has figured out how to fix it. because anytime someone out there post something about this error, it never gets any responses! please respond, lol cheers!
