  1. Just a minor issue with the walkthrough.

    The Google Apps link provided is for a set of Apps that aren’t compatible with the latest build. When I installed and booted the phone the keyboard fails to load and keeps flashing up a message whenever you go near an app that needs to use the keyboard.

    Also, not sure if I’ve done something wrong but the link provided to the ROM provides a download for KitKat not Lollipop. So currently I’m running 4.4.4. The google apps link provided is for Lollipop google apps which I think is why there is an issue.

    Sorted it now though and pretty good ROM. Not sure about battery life yet, although it’s always been pretty poor.
