Ok, let me get this straight. As of today at 2:20 am EST, Apple is signing 5.0.2 software, again.
Last friday I was trying to jb a friend’s ATV2 that was on 4.4.4. but had 3194 error on iTunes. That’s when I found out that Apple wasn’t signing anymore 5.0.2, hence the error.
I tried many methods. Saving blobs, weird workarounds, and suddenly I had an ATV2 stuck in DFU mode and had to update to 5.1. I still tried to go back to 4.4.4 with my saved blobs and never worked. 3 complete frustation days.
Then the miracle happened. While reading this thread http://forum.firecore.com/topic/8977 I realized that this user was certain that Apple was signing 5.0.2. I even replied that his proccedure was wrong because that couldn’t be possible. Posts later, someone wrote that he read in Apple forums that because of many issues with 5.1 on ATV3, Apple had no choice than having to re-enable the signing of 5.0.2, so this ATV3 users could downgrade.
So, with this 5.1 ATV2, I was able to downgrade in iTunes to an official 5.0.2 ipsw, then, once back in 5.0.2, I fired up season pass and let the magic begins. Now I have a jailbroken ATV2 who used to be 4.4.4, then 5.1 and then back to jb 5.0.2.
Ok, yes, I’m happy. so I suggest that if you accidentally updated to 5.1, NOW is time to go back, or save your blobs. Don’t know when Apple kills the 5.0.2 signing again.
I can vouch that works. Definitely use iTunes 10.6, the latest version is a nightmare of errors to deal with. Of course the easier way to find out if Apple is still signing 5.02 is to use TinyUmbrella and download all the shsh blobs for the ATV. If the 5.02 blobs appear, you are in business.
Tinyumbrella isn’t saving your blobs because you’re trying to save 4.4.4 blobs, not 5.0.2.
First, you have to upgrade to 5.0.2 in iTunes, with your device plugged, right clicking restore and choosing the clean 5.0.2 ipsw. Once in 5.0.2, and if you want to save your blobs, then you can use Tinyumbrella, or proceed to seasonpass to jailbreak
baruchin is right. After installing the clean 5.02 ipsw, if you use Tiny to save the blobs, make sure that the ‘Request SHSH from Cydia’ option under the ‘Advanced’ tab is unchecked (it is enabled by default).
Your computer is pointing to Cydia's server instead of Apple's. Because you are doing a clean restore you need to be certain that iTunes is using the Apple activation server to get the SHSH blobs. You could try this:
The easy way:
Open up TinyUmbrella, and in the ‘Advanced’ tab make sure that ‘Set Hosts to Cydia’ is unchecked. Close Tiny, put the ATV2 in DFU mode and try iTunes again.
The longer way:
On Windows, the hosts file can be found here: C:\Windows\System32\ drivers\etc\hosts.
On OSX, the hosts file can be found here: /private/etc/hosts.
A standard Windows hosts file should look something like this -
If you have any lines that point to gs.apple.com, backup the hosts file and delete the lines (using a standard editor such as Notepad). You may need to ensure that you have admin privileges. Reboot and try the iTunes upgrade again.
I’d Love to do this but am unable to get my ATV to show-up in the iTunes device list…
I’m using 10.5 (XP) and tried over the network (hardwired), USB (powered/unpowered), hittin’ the Shift Key, but iTunes never offers me anything to do with the ATV. I’m signed-in, home sharing, doesn’t seem to make any difference Also, why is “Create an iPad/ATV Version” always greyed out?
