I want to thank: zice; JarlPenguin; wiktorek140 and many others for their inspiration, advice and direct help.


The version for installation via TWRP is installed in the same way as any custom firmware. I recommend installing on those devices where the factory firmware is preserved, so as not to increase the level of the bootloader and you can easily return to ZUI.
