Thread: Pangu (in)security

    Default Pangu (in)security
    Hi, I was getting ready to sell my iPhone 5, doing a complete erase. The phone is at&t, had 7.1 jb'd with Pangu.

    When I went through the erase procedures on the phone, I got the Apple logo, followed by a small progress bar, then a daisy wheel. it got stuck on the daisy wheel for 20 mins...

    so i held the home and power buttons and upon restart, findmyiphone had been disabled, but the phone was otherwise the same.

    i tried again: same results. i then tried a remote erase by logging onto icloud from my computer: same result.

    to erase the device, i had to update to 7.1.2 (thereby un-jb'ing it). then i tried again and it worked quickly without issues.

    Pangu security flaw?
    Anyone else had this prob?

    First lesson........you never do erase all content and settings on jailbreaked iphone.....you have seen the result of doing it yourself.
    It doesn't have anything to do with Pangu

    What do you mean, why not. Because it happens every time you try to erase all content and setting on a jailbreaked iphone. Key word is JAILBREAK, it doesn't matter if it is Pangu, Evasion, Redsnow, Absinth........to erase everything from a jailbreaked iphone, restore is the only real option.

    As for that problem with FMI, I don't understand, how it has been disabled, sorry.

    It's not the erasure itself that causes an issue. It's the fact that the phone, which has a modified kernel not erased following a wipe, cannot boot without the various filesystem exploits that allow for an unsigned kernel. So erasing it to prevent data compromise from theft is sufficient, but doing it when you want to use the phone without another restore is problematic.

    TL;DR: Wipe after theft OK, restore all other cases.
