This Device Is Not An Ez-B Reports 69

I'm hoping someone can help. I have searched and found this topic mentioned several times and I have tried the solutions offered but still no luck.
I have done both a firmware update and updated to the latest version of EZ-builder. When trying to connect I get the following message:
This device is not an EZ-B. Please follow the online tutorials on the EZ-Robot website.
I have tried re-installing/repairing EZ-builder. I currently connect my developer kit through the router. I have reset back to factory settings and connect directly to the ez-b v4 but still get the same issue.
I have tried using EZ-B firmware update V4 where I get the following:
attempting connection on
connected to
Reports 69
and then in a separate window I get the This device is not an EZ-B error. When I click on the Scan for EZ-B v4 it finds two options:
EZ-B v4.x/2( EZ-B v4.x/2)
EZ-B v4.x/2( Camera)

If I select the top option and select connect I get the This device is not an EZ-B error and this dialog in green and black at the bottom of the screen:

If I select the camera option it says connect to EZ-B, not a camera. Batteries are fully charged but don't understand why it is no longer communicating with the PC?

Jeremie, first of all, a big thank you.
The only thing I have not tried is turning my home internet wifi off and trying to connect to JD, but this will have to wait as it is 2:27am and I need to get some shut eye, but I can confirm that our home internet wifif is
Hi Jeremie, I tried turning off the home internet wifi altogether and connecting to JD thru his wifi, but still get same response "this is not an ez-b"
I am currently laid up with the worst head cold I have ever had, so if you would be so kind to write up everything you think I should try, I will try them all in next couple days when I can get out of bed
thank you
Hi DJ, do I need to attempt to connect to my JD No Eyes or will it send the info from whats been saved to the EZ Builder on my laptop
It’ll  send what’s on the laptop. Click the link I pasted above and there’s detailed instructions including answer to that question:)
