When I leave the power cable in and go through the process, I get the rapidly flashing light, but it doesn’t stay. As soon as I switch from pressing Menu + Down and move to Menu + Play/Pause, the rapid flashing stops.
Start Seasonpass and let it’s do it’s thing until it asks for device in DFU mode.
Plug in your atv using micro usb /usb to your mac.
Plug in power on atv then quickly press the two lower buttons on your remote for seven seconds. Rapid blinking indicates that it’s gone into DFU mode and Seasonpass will indicate that it’s now working.
Quickly remove power cable.
Let seasonpass and Itunes do the rest.
This worked for me. The key is to remove power when rapid blinking starts quickly.
Just a note for everyone go has been running into the 5.2 update issues. If you’re still having problems running seas0npass do this:
For anyone struggling with the "filesystem patches failed" error, follow arpena's advice below for a fix.
It's a bug in Seas0nPass. In Mac OS X 10.7 and up, tar changed its behavior not to follow symlinks when restoring files. Ironically, it is the same bug evasi0n exploits in iOS MobileBackup to make the jailbreak untethered.
You can download the modified evasi0n.tgz from https://dl.dropbox.com/u/72403274/evasi0n.tgz to solve the problem. Replace your Seas0nPass.app/Contents/Resources/bundles/AppleTV2\,1_5.2_10B144b.bundle/evasi0n.tgz with this file and post here the result.
