K8203 upgrade problems

I’ve followed the section Vellman projects “2. Upgrading the firmware” and am still nowhere near getting firmware v2.2 installed.

Have now tried Arduino v1.0.6 as compiler and uploaded the marlin.ino code to the printer board.
(Printer with power on, USB lead attached, COM3 port selected, JPROG pins braced, lights on control board flash as data is transferred.)

Have not had to uncomment any lines in the marlin.ino configuration.h section.
See screenshot snippet.

Now what do I do?
Repetier-Host V0.95F has four buttons shown below:

“Reload Config”, “Restore factory settings”, “Save to EEPROM”, “Cancel”.

So I use “Reload Config” and then “Save to EEPROM” to save the new code settings.
Or if I wanted to revert back to firmware v1 I would use “Restore factory settings” and then “Save to EEPROM”.
Is that correct?

Some forum members have mentioned using M502 and M500 as g-code in the “Manual Control” tab. I’ve tried these too and I’m still at firmware v1.
What am I missing or doing wrong?
Can someone please help?

Asked this simple question in my initial post, can Vellman answer it?
