    I'm wondering what firmware is currently jailbreak-able... 100% legit

    Browsed the forum but couldn't really find anything.

    I have an iPhone 6 Plus with firmware 8.2 (12D508) but haven't come across anything saying that's okay. So, what firmware are you guys using to where you're able to jailbreak?


    Thanks!

    i don't know if there is a sticky, however this is a good site to reference for all your jailbreak needs...

    (direct link to their jailbreak wizard)

    I believe that it only lists the firmwares that are jailbreakable.

    Thanks!

    I guess the real question is how to downgrade to 8.1.2 (this looks to be the latest firmware with a legit jailbreak)

    8.1.2 is the latest that can be jailbroken.

    As of iOS 7 or unless you have an iPhone 4 or below there is absolutely no way to downgrade. SHSH blobs are relevant only with iOS 6 and below as Apple switched to APTicket with iOS 7 which is a completely different authentication system.

    The iPhone 4 and below can still downgrade because there is a bootrom exploit that can be used. Apple patched that bootrom exploit when it released the iPhone 4s and consequently no phone past the 4 can downgrade using that exploit.

    Sorry. But you're stuck until there is a jailbreak covering your version.

    Educate yourself a little a do some research.
    You cannot downgrade and the latest jb is for 8.1.2 nothing any higher than that.

    Quick question:

    Someone in the family upgraded their 5 to a 6. The iPhone 5 is running firmware iOS 7.1.1. Is there a way to successfully transfer my backup to this phone without losing the ability to jailbreak?

    Is it possible to jailbreak as is, then somehow transfer my backup to the phone?

    Your question is missing a few key information points so let me try and respond this way.

    You can always restore from backup with a jailbroken iPhone. That's a different thing than restoring the phone entirely which requires an update/upgrade to the latest signed firmware.

    But you cannot restore a phone from a backup that is from a newer version of iOS than the version the phone is currently on.

    For instance, my iPhone 5 is running 8.1.3. I could back it up but I could not restore from that backup on my wife's iPhone 5 because she is on 6.0.1. But I could restore from her backup to my iPhone because I am on the higher version.

    Does that make sense, and does it answer your question?

    ^Yes, it does. Thank you.

    My 4S is running the latest firmware, thus my attempt is futile.
