Remont and change a built image
Posted: Mon Sep 10, 2018 5:32 pm
<path-to-your-build-dir>/host/linux-x86/bin/simg2img system.img temp.img
mkdir system_root
sudo mount -t ext4 -o loop temp.img system_root
At this point you can make whatever changes you'd like to the files in system_root, i.e. adding apks to system/app etc...
When you're done just go back down to the output dir and do:
sudo umount system_root
<path-to-your-build-dir>/host/linux-x86/bin/img2simg temp.img system.img
You can now flash system.img using fastboot as usual.
