To explain it simply, it's "read only". Meaning, you can't write to it. Meaning, adb, twrp, nothing is able to write to it.thanks for replying even using adb push from PC is not going to work?
You can put a system image on there. Once you do, it is read only.
There is no way around this.
Other than creating a system image yourself that you put on there.
It's challenging if you've never done it before. It's easy if you have.
But that's the only way.
