  • Aine Boland

    When selecting things to wipe, should I exclude anything? Like tick any of the boxes in the Exclude section?

    • @aineboland:disqus For this firmware no, you will not exclude anything.

      • Aine Boland

        Also, when I was installing the drivers, 4 of them failed.. They were all sony/usb related ones. I tried multiple times. It just won’t work. My phone still connects and is recognised by my pc so is it a problem?

        • @aineboland:disqus you will have to disable driver signature verification in your windows and then install those drivers.
