Actually, technically speaking NCSettings was updated to fix the brightness issue but only when you use NCSettings to respring. I can't remember which update fixed it but one of the newer versions had a fix. If you use springtomize it will prolly still be dim. Or you can install the brightness fix that was recently added to Cydia. I didn't install it since I just quickly press the lock button while on the lockscreen when its dim and then its back to normal. I couldn't justify installing a tweak to fix it. Plus the cause of this problem was found so my educated guess is that any of your tweaks that respring the device will be updated with the proper method of respringing to avoid the dimmed screen.
