Why can't iPhones be downgraded?
So, here's the deal:
I love the way iphones look and feel, but why cant you downgrade them?
I would like to focus on an older one for the purposes of this article, like the iphone 4s.
Newer firmware slows it down. Apps crash. It lags.
I KNOW they use a kerberos certificate or whatnot to sign the firmware, and the iphone will only accept firmware signed by apple, but why can't you get around that?
Couldn't you just pop the sucker open and flash the darn image DIRECTLY onto the NAND?
is there some other way to FORCE the firmware onto the phone? not hook it up to itunes and stuff, but to simply copy the image onto the nand?
Это хороший вопрос?
