DISCLAIMER - USE AT YOUR OWN RISK - ANY WARRANTY WILL BE VOID !!!
@none has made this for us - it comes as is and is only for those who know what they are doing.
With this recovery you cannot flash zip files and Magisk apk has to be installed to use SU.
You can take backups and use Magisk Modules - but don’t try to update Magisk - apart from the manager apk. Once installed you will achieve SU privaliges - however - due to the security, it is limited to system-less root only.
You can unlock the pre-loader by setting OEM unlock in developer settings to ON
ADB reboot to bootloader
Issue “fastboot flashing unlock” and device will factory reset.
However - this will likely only allow you to flash unsigned boot or recovery images. Nothing else.
This means you cannot edit or change the super.img system.img etc etc …
