akkanman it’s likely your speed is low, I think default is fairly minimal slewing speed. Can you use the slider to bump the speed up and try that. The slider is in the main view the pop-out from the top right.
BTW you should only be using the USB cable, I don’t recommend EQMOD when you have high speed USB.
The modified OS is only to make a connection, it’s basically a driver update. If you are able to connect at all then you are fine from the update perspective.
