I made the mistake of restoring my apple tv 2nd gen. in itunes. I had done this before then immediately used Seas0npass to jailbreak. However, I quickly realized I was ‘boned’ when I saw there was only a tethered jailbreak for 5.2.1.
I have my computer and TV several feet apart and its rather annoying to cart my desktop over by my TV everytime I restart it.
How I downgraded?
1. First I used iFaith to grab cached SHSH blobs for my device. I found 5.0.1, and 5.2. Downloaded.
That is right. I have NEVER cached my SHSH blobs. I was completely surprised and it was a last ditch effort before I bought another Apple 2G off kijiji (I really love my XBMC + Live TV).
Make no mistake u2pop, his blobs were saved either unknowingly by him or by the person he bought the AppleTV from. One has to have saved blobs from their own device in order to jailbreak other than 5.2.1 and 4.4.2, both of which are tethered.
I’ve tried the exact same thing that you have, with the exact instructions that you’ve provided. Aside from a few niggles, it has worked!! Somehow my blobs were also saved from version 5.2, even though I physically never did this myself.
Yes, it’s not magic. As mentioned above, if you happened to use iFaith and Cydia even once, for nearly every release thereafter Cydia would do a query using all the ATV2 unique CUIDs that were uploaded to their site prior and save them… kinda like a public service.
There was a bit of a scandal where Cydia, after release ATV 5.1 aka iOS 6 - 10A406e (can’t recall the exact release) forgot to request something called an APTicket which is also required to JB, but did not save them along with the SHSH blobs. So any release thereafter didn’t have them to JB, which was required. Anyhoo… anything before a certain release was good.
So thank Cydia (for saving them for you) or your prior owner for using Cydia at one point in time!
