Could you post a short instruction set on how to carry out the downgrade so that we can maybe post this up for future reference?
Hi, many thanks for posting the info here.
I'm trying to update (or rather "downgrade") my ATV but for some reason it's not working. When I hold down the 'option' key and click on 'Restore Apple TV' I am able to select a file, but when I click on the 5.3 file I previously downloaded I get the message:
'The Apple TV "Apple TV" could not be restored because the firmware file is not compatible.'
I also tried holding down the option key at the next stage instead, where the popup window gives the option to "Restore and Update," but holding down the key had no effect whatsoever.
If someone has the later version, which software version did it originally use "out of the box?"
I seem to recall reading an article somewhere, (I wish I could find a link to it), that Apple is signing 5.3 only for the 2012 ATV3,1 (A1427) not the 2013 ATV3,2 (A1469). Apparently there were some minor hardware differences. I could not downgrade my 2013 ATV3. I got the same "Apple TV could not be restored because the firmware file is not compatible" message.
6.0.2
No buffering problems at all .
Hasn't the buffering issue been reported since 6.0?
Are you sure, because the link with all the firmware files has the list divided according to the model of Apple TV (Apple TV 3G, Apple TV 3G -2013-, Apple TV 2G...). Since they're listing 5.3 under the new ATV then shouldn't it work?
Right, so anything not signed by Apple will not get restored to ATV via iTunes?
That is correct. When you attempt to restore, iTunes checks with apple to verify firmware version.
So according to this: http://www.icj.me/ios/all#AppleTV32
...it is not possible to restore the newest ATV to any of the previous firmware versions?
I recently acquired an Apple TV3 with the hopes of a jailbreak being available... much to my dismay this isn't the case; although I am still looking. This was done WITHOUT SHSH BLOBS.
However, there's a guy on YouTube that displays how you can downgrade to an earlier firmware: (here's the link)

As per my post on another thread, I have just downgraded my ATV2 from 6.2 to 5.3 and its running smooth as silk. My brief instructions are below. I have only done this once and am writing the instructions from memory, but hopefully I havent missed anything out.
- Goto http://ipswdownloader.com/download-apple-tv-ipsw-files.php and choose your the correct v5.3 for your ATV e.g. ATV3 or ATV2
- Plug your ATV into your MAC via USB (for ATV3 you will need to use the power lead too)
- ATV will appear in iTunes asking if you want to restore to factory settings.
- When you see the box saying download and install, hold down the option key first. You will then get the option to navigate to your previousley downloaded firmware.
- Once you have selected the firmware the downgrade should only take about 5 mins to complete. At the end it will say your box can be unplugged.
- Plug back into your TV, run the setup programe and you should have a judder free ATV once again.
Hopefully I haven't missed anything out.![]()
