Android Things: Set screen resolution

Question

I have a small screen attached to my Raspberry Pi and according to the documentation for the screen:

Write the image to a TF card and append the following lines to the config.txt file which is located in the root of your TF card:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

You must make sure that there are no spaces on either side of the equal sign.

But I can't do this on the Android Things drive, as the disk image is not readable

these are instructions for the Raspbian OS image, not Android Things. Have you contacted the manufacturer to ask them for support? — Blundell, Jan 08 '17 at 21:49
I know what the instructions are for, I need to do the equivalent on the Android things side - is there any way to adjust a config file for the screen dimensions. — Quintin Balsdon, Jan 09 '17 at 09:35
the config file doesn't exist because this is part of Raspbian OS. You should contact the manufacturer asking if they support Android Things — Blundell, Jan 09 '17 at 11:28
fyi I might be wrong, see this question where he edits a file inside `/boot/` http://stackoverflow.com/questions/41558508/screen-orientation-on-raspberry-pi-3-with-android-things — Blundell, Jan 10 '17 at 20:10

The original answer was found HERE, and my saviour gave his answer HERE

Create a mounting position:

mkdir ~/mnt/sd

Mount the sd card:

sudo mount -t msdos /dev/disk2s1 ~/mnt/sd

Make changes to the config.txt, in my case:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

To unmount:

sudo umount ~/mnt/sd/
