SP Version 0.7.9 (265)
Mac OSX 10.7
Trying to go to 4.3 (iOS 4.3 - 8F455)
Started off with 4.2.1
I have done quite a big of hacking on my atv2 and I decided that a refresh was in order. Since I was going to refresh the atv2, I might was well upgrade to 4.3. I have my SHSH blobs saved and tinyumbrella running in the background. There are no issues with any of the steps. The issue comes after iTunes tells me that the restore was successful and complete. I disconnect the USB, let it sit for a few, then plug in power and HDMI. I get the blinking light onthe atv2 and the picture showing me that I need to plug it back into my pc (recovery screen I believe).
I even upgraded to 4.4 to see if a downgrade would solve the problem. Unfortunately it didn’t. I’ve replace all ipsw files and I just blew away my SP binary and downloaded a new one.
My next move is to try it on another computer.
EDIT: Tried on a different computer and got same results
Is there anything that I could be missing?
FYI - I used the same USB cable to do an untethered jailbreak less than a month ago.
