Hi.
I am desperate with my apple tv 2 5.1 firmware.
It was stock firmware, never jailbronken.
Last week i decide jailbroken it.
Extract shsh with ifaith 1.5.9
Cook a custom IPSW with sn0wbreeze signed with my bulbs, and restore itunes.
First restore, was complete… but at the end, i got a message failed verified 
Next times, i always get 1600 error just after extracting firmware (10 seconds at the beginning)
I’ve checked my shsh file extracted with ifaith, and i notice no apticket label inside the file. I can use this shsh file to build a ipsw with ifaith without erros ( i supoose ifaith check shsh files when build and signed a ipsw).
I dont know what i can do now. My apple tv is always blinking (reds0wn say Soft DFU mode), and is not funcional (not image on TV).
I’ve tried with severals micro-usb wires and 3 computers never got installed itunes… same result
I can re-extrat with ifaith shshs, and i get same shsh file before i restore first time.
Any help will be apreciated.
Thank you very much.
