Nice work but I still have issues with the sensor for adaptive brightness. Fresh install from c.48 on both slots. To be honest, it's a deal breaker for this ROM as a daily driver but I'll watch with interest. Many thanks.
C.63 firmware can also be flashed through adb sideload.
unzip all in one folder and simply double left click on updatefirmware.bat and it will do everything for you, including installling recovery. Also you need to be in the bootloader or fastboot in order to do this.
