Hello guys,
today I took the rs232 and usb cable (from the connectors to the board) from one r30ia controller to another, because on the second one didn't detect the usb (it was fine on "controller 1"). So I swapped just to check if it works and it did but then when I put it back to the original one (no. 1 controller), when I turned the robot on the screen on the TP went white and it said http 10.0 file not found. I fixed the situation with oppening the boot menu (after turning it on again) and select cold start. And all was good, thank good 
But I was wondering if any1 knows what caused this or maybe it happened to any1 before?
Thanks for all the replies in advance!
Best regards
