hobbywing LCD program box

[tonydevon]

Im tearing my hair out here.
I bought the above program box
connected it to the ESC, it wont work says I have to update the software

had to borrow a laptop, I only have a phone, no pc etc

hobbywing usb link software downloaded

connect the box and esc etc, get a message on screen saying to upgrade my software, I click update and it says I have latest version..

WTF

20 odd quid on a box you cant use out the box.

am I doing something stupid wrong?

hoping to take the car to its first race meeting tomoro but cant program the ESC
