Firmware

Firmware for both the demodulator and tuner are necessary. OpenELEC dvb-firmware collection includes firmwares for this device too.

They can be extracted also manually from the Windows drivers. Drivers (date 29.11.2013)

Extract firmware from file ttTVStick4400_64.sys in the zip (MD5 sum below): 0276023ce027bab05c2e7053033e2182 ttTVStick4400_64.sys

  • dd if=ttTVStick4400_64.sys ibs=1 skip=211216 count=17576 of=dvb-demod-si2168-30-01.fw
  • dd if=ttTVStick4400_64.sys ibs=1 skip=200816 count=3944 of=dvb-tuner-si2158-20-01.fw

Place the 2 firmware files in /lib/firmware.

CT2-4400v2

If you have the second version of the device, you will need a different firmware for the demodulator. Just get the file dvb-demod-si2168-b40-1.fw from OpenELEC dvb-firmware collection.

IR Remote Control

The supplied remote control is supported by the driver.
