MR1100 force generic firmware on branded modem

FYI, this is how I forced an EE branded modem to the generic firmware.

DO AT YOUR OWN RISK

Follow steps detailed here but with the fdt change below:

* Add "-force -r" to the fdt.exe command step. Like so:
"fdt.exe -f MR1100-100EUS_23113509_NTG9x50C_12.06.11.00_00_Generic_10.03.secc.spk -force -r"

I take no responsibility for bricking your modem, etc,etc...

Side note; if you run "fdt.exe -h" it lists all the valid parameters and help.
