I have an iPhone that was dropped in water. Once the backlight level goes below a certain point, the screen is completely black/useless. I need to go in iFile or some other file system browsing software to set the brightness level to 80% or something high. I've looked around and found the backlight level for SB Settings but I'm not sure if that will work. Anybody know where that setting is?
User > Library > Preferences. The property is called "SBBacklightLevel2" in the com.apple.springboard.plist file. Thanks @Andrew Larsson for the confirmation of this.
