Hello, anyone successfully downgraded from iPhone5 iOs 10.3.3 to iOs 6?

If yes, how?

If Apple has stopped signing an iOS version, then there's no way to go back to that older iOS version. It wouldn't be considered illegal, per se, just not possible (without modifying the hardware, such as replacing the logic board with one that has the iOS firmware installed. So, you would need some luck to find that...)

One way to get that older iOS version: Find an older iPhone (an iPhone 5) that has not been upgraded from iOS 6
Sometimes you do get lucky on eBay.

I see. The other ways non-officially are considered ilegal? Thanks.

There is no way to do this, legal or otherwise.

Edit: Sorry, everything MacRumors is taking like five minutes to load and by the time I get around to being able to submit a lot of time has elapsed.

Jailbreaking can allow this. Although if you don't know what an SHSH blob is then it's unlikely you have what you may need.

I've heard that there is a downgrade for the 5 out there but have not looked closely at it. Involves jailbreaking though.

10.3.3 is jailbreakable.

Can you elaborate on this for a newbie? Thanks in advance. (not sure how to send a PM so posted here)
Apple prevents downgrading by requiring that all iOS firmware be digitally signed. iTunes checks with Apple that the firmware you want to downgrade to is signed. If it's not, then it will not proceed and you get an error.

Sometimes there is a glitch in the Apple matrix and older versions of firmware randomly get resigned. This allows someone who is paying attention to downgrade.

It's happened more than once, but Apple has always caught the glitch and fixed it. The suggestion is that you are watching this link in the hopes that another glitch occurs.

If you decide to do that be aware that it's going to be like watching for that thing in the corner of your eye to appear. You'll probably spend an eternity and never catch it.
