Since some of us installed T-mobile firmware on devices from other carrier or factory unlocked devices from Samsung, this menu helped me to get rid of T-mobile's annoying Magenta boot screen.

Thanks to following people to help test Android Pie build and report the features that are broken or not working:

Thank you all for great support to this thread. As the pole suggested to include new features on each builds as well for that I will need some help to compile list. If anyone is interested to help and test to compile a list together with me, it will be much appreciated and list can be compiled faster. Please PM me
