Jailbreak from 4.4.2 to 5.2

I’ve successfully downgrade my Apple TV to 4.4.2 tethered from 5.2.1 and have installed atv flash black and have backed up the firmware and it lists 5.0.1, 5.1 and 5.2. When I try to jailbreak it in seas0npass I get an error message when it’s in the last stages and its says critical error.

I have also tried snowbreeze and it works fine up until I restore in iTunes and when it’s validating I get error 1602.

Does anyone have any solutions. Thank you for all your help.
