    Hey Guys,

    Having a bit of a mystery here, I've had iOS 10 on my 6S since beta 1 but I've been getting awful battery life and a few frustrating problems so trying a DFU install in an attempt to resolve it.

    Ive done DFU installs many times so completely familiar with the process, I've downloaded the beta 4 IPSW direct from our Dev account with Apple, also installed Xcode 8 Beta 4, updated iTunes however every single time iTunes is saying the installation file is corrupt.

    Ive downloaded the IPSW 5 times now on different connections and browsers to no avail, has anyone got any ideas before I go insane?

    Ive also tried doing a standard restore rather than going through DFU with the same results.

    Appreciate any input!

    Try an update rather than restore? I believe current iTunes in Sierra is also an incomplete product.
