    Don't know if this still works.... Downgrading Via Desktop Manager Is Easy

    Not sure if Viber still works, but this site has copies of some of the older apps BlackBerry OTA Downloads

    This page will let you download old BBOS Verisons. It's for AT&T phones, if you are on a different carrier I can find the link for you if it exists...

    You'll also need the Desktop Manager.

    I just used these downloads to downgrade my Pearl 8100 to OS 4.2 from 5 and it worked great!

    Wait... The torch shipped with 6, whoops! Looks like you are stuck with OS6.

    I had the 9800. It released with OS 6. There is no build of OS 5 for the original Torch.

    Remember too that each legacy OS was made for a specific phone. A build for the 9800 only worked for the 9800. There were very few builds that worked on more than one specific model.

    Now, within each model, a build released by one carrier for a specific model actually worked with all models regardless of carrier any of the other models were on.

    I know that the last AT&T version of 6 was build 600. But, builds were being released by other carriers for over a year since 600 came out. The last I used was 749 before I finally left for BB10.
