Apple TV Jailbreak iOS5.1 untethered (5.1.1 update)

This is what we have been waiting for... and untethered jailbreak for iOS5.1

Firecore just released the untethered version of their jailbreak. so far i've been using the tethered jailbreak provided by firecore. i'm a little concerned that the new jailbreak will break my setup again since many people have complained that they can not install xbmc on it.


-- Update --
now that there is another untethered update i ventured and tried to update my atv2 to untethered jailbreak. since because of blackouts and stuff, i need to keep booting it up with my laptop.

i updated to the new season pass tool for my mac and then run it to generete the ipsw file. it did with no problem. but the season pass tool script to upload via itunes failed to execute properly. i read that the script does not work well with Mountain Lion. Since i know that season pass created the ipsw file in the same location as before. i just opened itunes and put the atv in dfu mode. next itunes recognized the "device in dfu mode" and presents the restore screen for the apple tv. so i just pressed the option key and clicked on the restore button. this opens finder so you can browse for the ipsw file. once you select the ipsw file you want to update then it just went on and try to restore the firmware.

some problems that i run into while doing the firmware update were the infamous errors 1602,1604 for 1602 i remembered that it had something to do with the apple server for firmware validation... so to solve that problem you have to check that the /etc/hosts file does not have the cidia ip address for the gs.apple.com dns. In my case it was put there by tiny umbrella application that i used to update the firmware earlier. once i removed the entry on the hosts file. the firmware update seemed to proceed, except that i got the 1604 error which seemed a little more odd since according to apple website means that there is a timing issue with the usb cable, so they just tell you to try a different port or a different cable. since i know that my cable is ok since i used it to flash the firmware before, then i was a little frustrated. but once method you can use to test your cable is to just let itunes restore the official firmware to the atv. that way if its successful, it means that your cable is good.

another reason to let it update the official firmware is to let the atv be in a 'good' state so when you go to flash it with the hacked firmware you just created with season pass then it should work correctly.

and i think that is what happened in my case, after like 10 different times trying to flash the season pass image, i flashed the official ipsw, then the next time i flashed the season pass ipsw it passes the point of failure.

after all this pain and suffering, you should back up your ipsw, your apple tv shsh file (tiny umbrella) and the xbmc catalog.

so until next time, its all couch surfing ....
