Amlogic Android tool

[luciferyelow]

I make custom firmware for x96s.
I need to set default 720x480 resolution after hard reset.
As I understand, DroidTvSettings.apk or amlogic android tool, write resolution screen information in one of system files.
Please help: what file I have to change and what information?
Maybe anyone could share with me source code of amlogic android tool?
Maybe anyone has contact of author of amlogic android tool?

I want to find out about this too. I own a tanix TX5 plus and want to port the display settings from DroidTvSettings.apk to custom ATV firmware. Slimbox SlimBOX TV — ????????, ????????? ??? ?? ?????? ? ?????? and xvortex Download | TvBox-Vortex (xvtx.ru) should have custom firmware for x96s and maybe you can decompile and look at their TvSettings.apk under /system/system/priv-apps
Alternatively, forced resolution maybe easier with init.d user script rather than modifying system settings, but I am no expert
