Android 9 install Mmnc

Hello friends, I am trying to install the image of Android 9 in my Mmc memory, I use etcher, when I select the image, this message appears.


I click continue but then I install the Mmc on my rockpi4B but it won’t start.

There are 2 types of firmwares.
GPT, it can be flashed with ether or rkimage firmware that can be flashed from a PC with rkflashtool/AndroidTool.

You should use GPT firmware if using etcher, then just unzip it first.
