I have a 5100max running 7.3.0 build 19. I want to have ZAGAT on it but I can't buy this from anywhere. I have played around with 7.4.2 and I noticed that it has the ZAGAT already activated. However, it's a bit unstable so I went back to 7.3.0

I read somewhere that the device.xml has the ZAGAT codes, but even adding the device.xml from 7.4.2 does not seem to activate ZAGAT on my device. Any suggestions?
