hi Guys
just built my i3 pro B printer with no problems just a blown fauilty power supply. on trying to home the axis the y axis is going the wrong way.
after reading about this problem am i correct in saying i need to change it in the firmware. i have installed easyprint as this looked the easy way to upload new firmware, being built into the software. i tried to up load the latest version 1.0.04 from 1.0.03 installed just to see if it made a difference.
nothing happened? so 3 questions really am i on the right route to reverse the drive, what do i need to change and why has it not up graded the firmware anyway

You can refer to this:

Try to edit the firmware and upload it with Arduino.
Sometimes you need to try twice because you don't know it is true or false in the first place.
