Ok, So i pulled down the 4.5 OS for my ATT 8300 from the sticky link, removed the vendor.xml file, and started the update. I get to the point where net_rim_cldc.cod starts to load and get a error "A fatal error has occurred while updating your device's softwarre. Please try again." Well I have tried the update 5 times with the same issue. I pulled the battery and tried with the same results. I have even wiped the deivce using jl_cmder. My only recourse is to remove 4.5 and reinstall 4.2. Anybody have any ideas here?
