[Sony Xperia S, Acro S, Ion] millosr:
The purpose of this rom is to provide a rom not so far of the AOSP with some cool features (nAOSP means "near AOSP").

This rom is legacy of [MENTION=6043081]mickybart[/MENTION]'s work from 5.0 to 7.1 versions. He also did initial rom setup for oreo.

This version is based on [MENTION=2233641]AdrianDC[/MENTION] oreo port for huashan/blue devices.

NOTE: Please read this post before flashing b05

Root

This ROM has built in superuser however since b10 it is also possible to flash Magisk, by using Boot Bridge:

flash BootBridge-Init.zip

flash Magisk zip (currently Magisk-v20.1.zip)

flash BootBridge-Restore.zip

Built in superuser is official/preferred root method and I will not fix issues with Magisk like not being able to reboot to recovery.
