The Official firmware files provided here contain an anti downgrade mechanism.
This can be bypassed by simply changing the name of the update file to that of a higher version number currently installed.
To download a modified Firmware file, check the Downgrading box and then click the desired Download buttons.
A file starting with 90.**.5 will be downloaded, where ** is a random number to avoid collisions in your downloads folder.
We recommend once you've downgraded, to delete these files as to avoid future confusion!
