Windows Phone build tag: 8.00.9690.412.WPMAIN(wpbldlab).20120511-1730

This is a ffu for a RX-100 Gen 2 device but it's backwards compatible with Gen 1 devices.

Resolution is set to 768x1280.

FFU file was converted from a raw device dump after it was cleaned from user data.

Notes: This build by default will not boot due to wrong security permissions set on the Data partition.
It will instead hang on a black screen. To fix this issue, boot the phone into mass storage mode by pressing the volume up button at boot.
Then open disk management, find the last partition of the phone disk, go to properties, go to the security tab,
change the ownership to everyone, and select full control for each user that you see.

Additionally a software reset on the phone can fix this issue.
