    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.
