I found a method to change System Status in Odin mode to 'Official/Samsung' that is very simple and only using the busybox application "devmem". Use this command in adb shell or terminal emulator. Just type it in, hit enter, and reboot. Bam.
devmem 0xF91CF8C 32 0xFF000000
This will change your status to Official and remove the padlock with 'Custom' on it. If you want
'Custom', replace FF with EE.
Immediately upon reboot, Odin mode and the device recognize the device as official.
The explanation is that this is from a small region of memory that stores what's known as DDI data. I don't know what that means yet, but some other information like the CC Mode flag and device name/product number are stored here. I'm still doing further research on what else resides here.
