Just grab a debrick image for it.. The various version files are present in various topics in the forums..
If you need specifically. Bar files you can find a couple of pastes of links by xsacha for a couple of versions.
If you need bars of BB10 you can use Sachup tool by xsacha (uses the latest server api for bb10)..
There was a script by yohanes to get 2.x bar files but I think the server api has since changed and doesn't work anymore. And Sachup doesnt support the older server api..
For all of these the forum search function.
