I canβt say about a specific implementation, but, of course, this can be achieved without creating custom firmware or without rooting the device.
This application on the SureLock market claims to launch the device in kiosk mode and is available for Android 2.2. I do not think there are any root rights.
Discussed here and here . According to their description, they started at startup and in full-screen mode. Thus, either you can use this application, or find out how these gyu did it. good luck.
PC.
