  1. In those installation steps, you forgot about the downloaded Gapps package, which also needs to be installed. Otherwise, this 5.1.1 slim package is not very suitable for the i9195, because the “back” and “menu” buttons on the device are reversed than in the installed slim version. The bar display must be set in the screen display settings menu because the original phone buttons do not work.
    But I still thank the author for this ROM package.
