So my Pearl was being wonky this morning (like most mornings, sigh), and I pulled the battery. It booted up to App Error 200. I reseted, repulled, repeated about 10 times and it still went to this error. I wiped it with JL_CMDR, but now it boots to error 507. Desktop Manager won't recognize it, and subsequent wipes take me back to error 507. Strangely, it's visible in BlackBerry Device Manager, even though I can't see it in Desktop Manager. How do I reinstall the OS? I'd take a blank 4.2 at this point, though I do have a recent backup from Desktop Manager that I'd like to use.

Thanks!

Download and install the handheld operating system for the 8100 from either T-Mobile, Vodafone or O2. Personally I would use O2 as it is the newest. First download it, then execute the downloaded program.

Locate and delete VENDOR.XML on your PC C: drive

Restart Desktop Manager with the BB connected.

The reload should start.

No dice. Desktop Manager doesn't see my pearl (Disconnected).

Did you try and start Application Loader?

After you do a wipe, you have to manually load App Loader. It will then sync up with your BB and ask if you want to install the new OS.
