I have a click plus C2-03. When I first received it, I was able to connect to it with the latest software. I was walking through a tutorial trying to teach myself how to program PLCs and one of the steps in the video was to update the PLC firmware. It failed a few times but eventually I was able to get it to 100% but it failed again, this time on the 2/4 phase(main CPU) update. Now I can no longer even connect to the CPU. 

The connection test passes.

The button to Blink ERR and RUN button does make the lights blink

I have tried multiple USB micro cables.

I have deleted AppData folders, uninstalled all drivers, uninstalled the software. Rebooted my computer several times. 

Reinstalled the software and drivers.

I have also factory reset the CPU both using the software app and holding the BT button for the 5-6 seconds.

I have done all of these steps without any modules installed and while in STOP mode.

The CPU is recognized as a Click Plus on the COM port in device manager when plugged in. I then try to connect to the PLC. I am greeted with a message that the firmware on the PLC is a higher version then what the programming software supports (this doesn't make sense as I am on the newest software v3.92). I am given the option to either download the newest software from the website, or to "downgrade" the firmware to 3.92. When I attempt to "downgrade" to 3.92 that is when I am met with the PTC-005 error. 

I have tried to use an older version of the software(v3.71) and am met with the same error. 

I would also add that the ERR light does come on when I power the unit on. When I power the unit with only the usb cable the ERR light comes on solid after 6-8 seconds. If I power the unit via 24V the light comes on immediately. If I factory reset the module while it's powered on via 24V, the ERR light will go off but comeback solid 6-8 seconds after the CPU restarts. 

Is there anything I am missing?
