hard reset Eten m600+

[Guest Nichico]

i followed instructions from a reply earlier on a question how to hard reset the m600. What i understood was that i had to push the reset button together with power button(control+alt?). But this only results in a soft reset in my case...I probably do sth wrong, so, please who has the right advice? Thanks in advance ....My backlight ony works one time after a soft reset, switching the device on again results in a dark screen, can read it under a lamp...so the backlight isn't going on again...so i hope a hard reset might help.
