    Hello everyone.

    I'm new to this and I'm writing this because I would like to jailbreak my iPhone 5s GSM. It's on iOS 10.3.3 right now. I guessing I have to downgrade it to iOS 9.0 in order to jailbreak it. But I have no idea how to safely downgrade it in the first place. Could anyone help me out? Is it even possible for my phone to be jailbroken in the first place? Please help and let me know if you need more information. Thanks

    You can't downgrade it.

    That's correct.

    As you said you're new to this I will explain. Apple does not like jailbreaking. So they make every attempt to prevent you from jailbreaking.

    One of those methods is to digitally sign firmware versions. Your device is the lock and only Apple holds the keys. As long as Apple is signing a firmware you can get the key and downgrade/upgrade to it.

    But the moment they stop sigining a firmware you no longer have access to the keys and are prevented from downgrading/upgrading to that firmware. Apple typically stops signing older firmware anywhere from a few days to a month after release of a new firmware.

    There have been workarounds in the past, but unless you have a certain device (mainly a 4s or less) and certain firmware you can't use them. Your 5s is 64 bit on iOS 10.3.3 so you can't.

    There is no way to fake the digital signing and fool iTunes to install an older firmware.

    Which is why, when you have jailbreaking in mind, it is always best to stay on the lowest version of firmware you can. Consistantly upgrading to the latest version almost guarantees you will never get a jailbreak.

    Thanks for the advice. So would downgrading to 10.3.2 while I can be a good idea?

    It would not be a bad idea if you can.

    It's too late. Apple has stopped signing 10.3.2.
