I want to downgrade my Apple TV 3 from 6.1 to 6.0.2. But when I connect the device to iTunes and select .ipsw I get an error saying: "Could not be restored because the firmware file is not compatible". Is there anything I can try to get past this? Or it is not possible to downgrade at all?

You cannot downgrade a ATV3
You can on a ATV2 if you saved the SHSHs
No posible in your case.

when you install software on the aTV, it checks in with apple to make sure it can install that software. Apple typically only "signs" one version at a time, so the current version, and sometimes for a few days after the new release the previous version, but that doesn't last long.

so doesn't matter what version of hardware you have, if apple is no longer signing the version you want to install, you're out of luck.

the SHSH blobs that cyber mentioned are the info that is generated by apple signing that version of firmware and saves it, they are specific to an individual device and version of software. Currently you can only access/use them on the aTV 2, and you would have had to save them when you had the old software installed.
