Hi all! I'm new here. I just bought an ATV2 with stock 4.2.2 firmware. After doing some internet search i think i'm out of luck in upgrading to 4.4.4 and untethered jailbreak it. My only options seem to be: 1. Backup my 4.2.2 SHSH blob using iFaith and jailbreak it with Seas0nPass. (According to http://forum.firecore.com/topic/3418 4.2.2 should be untethered) 2. Backup my 4.2.2 SHSH blob using iFaith and upgrade to 5.0 and tethered jailbreak (if i'm not happy, i can revert to 4.2.2 using my SHSH blob and jailbreak it under 4.2.2 untethered???) Am i right, especially the second option in that i will be able to downgrade to 4.2.2 with my backed up SHSH blob? It seems nowadays jailbreaking ATV is more complicated so i want to make sure that i don't do something only to regret later by not having the right knowledge. Thanks for any help!
