i am looking for instructions on how to do a complete "wipe" of my 9780 and load the specific software that i select?

i used jlcmdr or whatever its called....that wiped my bb clean no problem....but then when i tried to load the latest software by using the links here and using the apploader it would not do it....

the only way i could load new software was to run the desktop manager/software and that would only let me load the software from my specific carrier....

is this normal???
