LINE Clova desk smart display

Post by mouse_soft_y »

Hello. I am trying to modify the "LINE desk" smart speaker/display from the Korean company infomark.
The information I have researched is listed below. (It is in Japanese so please use Google Translate)

adb goes into engineering mode and can be enabled, but it is blocked.

I found that I can get more debug items if I can enter demo mode as a result of reverse compiling. So I did some research and found that the /system/bin/keyevent program is responsible for monitoring key events and switching to demo mode.
This program performs a factory reset and a demo mode based on key input.

The factory reset is performed by pressing the mute key and the power button for a long time.
However, I do not know the key for the demo mode.

The following is the result of the reverse compilation, but the variable and function names are unknown and difficult to understand.

Here are the variable and function names as best as I can.

Could you please help me to analyze under what circumstances the demo mode is triggered? Thank you in advance.
