I tried to install this for my G7-L03 from Wind Mobile and got a boot loop, but when I tried to flash the CM12.1 ROM it works fine. I think someone posted that you must be on Lollipop originally to be able to flash CM13.0, is that true? My phone is originally on Android 4.4.4 (EMUI 3.0) so is that the reason for the boot loop?
