Good day XDA users.
These days I'm try to understand Mi A1 system partitions, and it's quite difficult and new for me.
My main goal is to get MIUI working on my Mi A1 phone.
I was able to save leaked Oreo ROM to system sparse format, also I prepare an easy tool for flashing that Oreo ROM via fastboot scripts.
