Thank you for your reply!
I've been reading on this forum a lot already and came across that post as well.

I've been unable though to enter the preboot mode on my device. When I hold my finger in the left upper corner during start up, it will enter screen calibration mode.

Also I've been unable so far to download firmware for the 1695 (or is that not required with this method?), apparently it's not a very popular model, although I liked it a lot until three days ago.
