Jailbreak problem

Hi every body, 


I have a atv2. This one was jailbreaked in 4.3 with season pass.

My son have made an upgrade of my atv in 5.3.

I have a lot of shs saved on my computer with tinyumbrella but i can only restore in 4.3. 

If i try to downgrade with another one, i have an 16xx or 11, 21, … error for the downgare.

I have the same error when i try to jailbreak my atv with season pass.


Have somebody a solution for this problem?






the only solution is to switch to 4.4.2 tethered
