Default [Q] Samsung gt-s7562 duos won't go into download mode

Hi everyone, I hope someone can help with this.

I have the Galaxy S duos which has problems with connecting to data for both sims. I am trying to flash a later formware in the hope that it is more stable. I have the firmware, kies, odin and drivers.

The problem is that the phone will NOT go into download mode. When I press and hold the vol down/menu/power buttons I go into a Factory mode instead of download mode - the following options are available in this mode:

Full Test
Item Test
Test Report
Clear eMMC
Reboot

When I press and hold the vol down/power buttons I go into Recovery
Is there anything I can do to get into download mode??
