I've just finished building set 42131 Cat D11 Bulldozer, but unfortunately I couldn't do the final calibration before driving it...

I carried out the tests during construction and everything was OK.

Now, at the first stage of calibration, the shovel goes up and down correctly and then nothing, the application freezes without going on to the next stage...

Thanks in advance for your answers!

  • Did you solve the issue? I have the similar issue, on the second screen of the calibration process, the ladder goes down, then up and then the gear on the picture in the app is still rotating and the calibration process stuck. No idea how to continue...
