I did a System Restore and went back to scratch. I just shorted the RST and GrD and it went into bootloader on regular basis. I then tried Firmware Upload and it went through the process and it said successful and drivers were good and finished.
Only thing now is, with Pro Micro attached to PC and only Reset and Ground wires attached it, Device Manger HID list does not display the Pro Micro as per instructions. Is this correct?
Are you sure you are not still shorting the Reset button ? you are using a momentary switch for that correct? you would see nothing in DM if the reset button is ON constantly via twisted wires or a toggle switch in ON position etc.
The 8 sec change of COM port is normal it is going into Bootloader Mode, it is during that 8 secs you need to press the Upload Firmware Button .
I have found that a double tap of the reset button works best for getting the Leo/Pro into bootloader mode.
