Check the sticky at the top of the 9300 section and find an OS for your specific device. Follow our instructions to install it. You might need to wipe with Jl_cmdr first (see the FAQ).

Using "Google" and typing "BBSAK" in the search box, I found this site for you -> BlackBerry Swiss Army Knife

I think the easiest way to downgrade your OS is to trade for an Android phone. Just sayin...
