    Hi, i read the other posts on how to downgrade, but still got no idea (and i tried), I am trying to downgrade from OS .607 to .517 so here are my questions:

    I downloaded the 9550AMEA_PBr5.0.0_rel909_PL4.2.0.250_A5.0.0.517_Sa skTel installation file and ran it, it just said whether i fix or remove. I did remove and reinstalled it, with my phone plugged in all the time. maybe i downloaded the wrong thing, not sure

    I also used the Apploader in the CommonFiles folder, but the OS part didnt even show up and i have no idea what to add and where it would be.

    Please help, thanks

    You have to install the 517 OS on your PC AND remove the 607 OS from your PC. When you do that, the App Loader will see that the installed OS is earlier than what is on the BlackBerry, and will offer to downgrade it.
