Typhoon Q500 led keeps blinking red

If some repair on ESC or motor was done a complete Motor-assignment is absolutely needed. But for this you need the GUI working.
First step is to check if driver are correct installed. If you plug in the white cord (this is a simple serial to USB converter by the way) to th PCs USB in Windows Device Manager should appear a new device for COM&LPT.
A virtual COM port should be assigned to this device, a COM number (here COM3). If so, all is OK. The GUI should recognize this COM port by itself but can also force it to connect to it.

The problem may then be the tiny connector inside the battery compartment. Please check if no pin is bent (4 pin in total) and wires are OK.
Wires and pins are all good
 
Looks like the last home hope is to look for wires that are attached to the wrong places.
This first drawing covers the GUI/Receiver connection on the main flight board. The drawing covers both original and 4K versions, so be careful to look at the one that matches yours. You will notice in a couple of places the wire colors do not make sense. Red is ground and black is battery positive, is one example. The one that really causes problems is when the wires switch colors at various connectors, even though it is still the same wire number:

This second shows the wire order from the GPS module:

Thank u for the pics. Everything to me looks fine I could post cpl pics if that would help anybody figure out if anything is wrong.. Here's a question. Could I take the board from another drone and make this one work?? I know I wouldn't b able to use the q500 controller or camera, I'm just asking is it possible?!?!
