I have got a SpeedTouch 546v6 that I would like to downgrade to be able to use DMT's full functionality with it. I am looking to downgrade it to firmware 6.1.0.5. I have managed to downgrade it to firmware 6.1.9.6 but it won't go any lower than that, I can upgrade it but not downgrade it any further than 6.1.9.6.
When I use the downgrade wizard it get's to about 30 percent and then it says "router rebooted in the wrong mode" and then I have to upgrade the router to get it out of kernel mode. This was with a static IP.
I got the firmware from here:

What can I do?
