The IA6 I believe is a receiver, do you mean you are upgrading an FS-I6 transmitter?
1. Do you have the data cable: FS-i6 Data Cable from banggood

2. You have downloaded 10ch_MOD_i6_Programmer_V1_5.exe
3. Run the EXE file as administrator, no need to view raw data, that I can remember when we upgraded my sons TX.
4. Connect data cable to TX and plug into USB port (As you plug it in, monitor device menager so you can capture the com port number)
5. Hold both sticks full down and left and power on the TX to enter factory menu
6. Select Firmware update and say yes to the warning
7. Now on the programmer software select the proper com port. Once you have selected the correct com port the Current Firmware version will display (1.10 likely)
8. Click on program,when done the TX will reboot.
Hope that helps
