Step 6. The checking procedure does not end here. You will have to check for Cross-version support here by entering the commands given below –

adb shell

cat /system/etc/ld.config.28.txt I grep - A 20 "\ [vendor\]"

Step 7. Now see if you can find ‘namespace.default.isolated’ with its value ‘true‘. This suggests that your device is compatible with booting Android Q GSI on the top of the Android Pie 9.0 Vendor image.

cat /proc/mounts I grep -q /dev/root && echo
