Default Cannot load OS

Please Login to Remove!

I have a 8220 that I was attempting to downgrade the OS to the T-Mobile .180 version OS from a beta OS. I have loaded a few different operating systems on this phone with no issue until this time.

Every time I try to run the Apploader, it gets to where it starts to install the cod's and then stops and gives me a fatal error message. I have tried every method I could find including:

using Jl-Cmder to wipe it

adjusting the power options on my PC for the USB Root Hubs

beginning installation without the battery

using the online updater

switching PC's

uninstalling then reinstalling all blackberry software

I don't know what else to do! If I have missed something, please let me know.


I keep getting the 507 and 561 errors on the phone which I know indicates no presence of an OS

phone hasn't been dropped, gotten wet, or taken apart

exact error message received every time "Errors: Unspecified error encountered [J:0x00000005]"
