DESCRIPTION

First of all

if you want an stable upgrade, i would prefer my LOS-ROM. They are both stable and can be used as daily device. This offical ROM has some "malware" apps and installed by cubot automatically. Actually, i don't know how critical are these apps. Otherwise take a look on my other ROMS directly for our device:

Stable LineageOS13

Firmware
