    Hello,
    I am trying to decrypt the iOS6 firmware using vfdecrypt and the needed keys from http://theiphonewiki.com/wiki/index.php?title=SundanceVail_10A5316k_(iPhone_4_CDMA)
    I run the commands, and it builds a new .dmg, but when I mount it it gives me a "no mountable file system" error. I have tried this for both iOS6 CDMA and iOS6 GSM versions, no luck. I have used vfdecrypt before, in the exact same way, and it worked fine. Has anyone been able to decrypt ios6 or know what is wrong?

    What are you using to mount the .DMG?

    I'm getting the same issue but I used a different program to decrypt it. It must have protection on it or something

    I tried this on Windows 7 and I can't open it with any zip opener I have. I think with the implementation of KASLR and preventing us from opening IPSW's, Apple really doesn't want us to look inside iOS 6.

    I got it, but when opening the dmg I get an "invalid checksum" error. The command I used (after cd'ing into the command's directory) was :

    ./dmg dmg /Users/...(path to ios6 dmg) /Users/(path to output dmg) -key 781f6676b6a7ec5d44d67cae5103736062c6229b8194b26f9782cb638d7f9c388990ff80

    I am extracting an iphone 3gs ios6 beta 1 firmware

    I think the syntax should be "./dmg extract [input.dmg] [output.img] -k [key]"
