Need to downgrade to iOS 9.0 or even 8.

[Chew Toy McCoy]

I have an iPad 2 (not air) that I want use strictly with an iCade. I don't think they even make the boxed iCade anymore, not for years. It's a brilliant bit of kit, however mid revisions of iOS 9 broke the ability for it to connect through bluetooth as has every iOS version since. I just need to downgrade to get it to connect and then I don't plan to connect it to the internet ever again. Just a nice bar top retro game machine.

So is this kind of downgrade even possible?

I believe, no.
Not possible anymore.
Don’t know if jailbreaking could allow you to downgrade the firmware.

I'm sorry, but no. Unless you have a jailbroken version of iOS right now, you can't do this. Apple doesn't sign iOS 9 or earlier, and the device will not let you install an unsigned OS

 

[Chew Toy McCoy]

Well. Crap.

 

[casperes1996]

Well. Crap.

Sorry :/. It's for security reasons

Nope.

 

[casperes1996]

Nope.

There's supposedly a tool in development for it

Doubt it... You'd have to crack iOS itself, or simulate the activation servers with the proper certificates and such, Not saying its impossible, but the chances of anything working are 1 in 1 billion, if not worse...

You can if you're on 9.3.3 or some various other specific versions of iOS and jailbreak. Otherwise, no.

The iPad 2 from the 2010/11 era CAN be downgraded to iOS 6. I did it a long long time ago and I know it still works... Do some googling for a tutorial, it's a pain to get working but I managed to do it after a few hours of fiddling around.

So I found a way to download the right iOS downgrade file to iOS 8 and it starts in iTunes but then it pings Apple who of course won't authorize it.
