Homebrew No backlight in gm9?

[MercusMassacre]

I just updated Luma and now gm9 has no backlight. Another problem that arose is that as soon as I open Luma settings, the system reboots. Help? gm9 is kinda important, I'd say.

GodMode9's brightness can be changed by the 3D slider or by pressing the HOME button, then going to "More...", then "Configure brightness"
As for the Luma settings, I'm not sure
