Launch Android settings without launcher shortcut?

Hi,

I got a question and hope anyone can help with it:

I have a brand new android device (Tolino Shine ereader), which is using a locked UI where normal Android-apps aren't accessible. So I can't get into the settings menu (to turn on USB-debugging or allow unknown apk installations) or launch any apps. The only default Android app available is the internet browser.

ADB is disabled. System Recovery <e3> only shows reboot and reset options. No other options present.

Android Version is 2.3.4.

Is there an option or a trick to access the default android settings? For example by putting in some shortcut into the browser or setting up an html file to launch an activity or something like that. I already used google, but came up with nothing. Maybe someone here has an idea.

thanks,
chalid
