We were one of the adventerous souls on Robot C v3.06 and now trying to downgrade back to v3.04 after our robot went in circles uncontollably in some matches Saturday and continuous Vexnet drop outs. What is the proper procedure for downgrading?
We uninstalled robot C from the control panel and reinstalled v3.04 from a download. That went great. RobotC downgrades itself nicely prgogram-wise, but the Cortex will not recognize the computer now for firmware download via USB-USB cable.
We tried the Cortex config button sequence but that seemed to have no effect. The old program was still in the cortex and we could not get the old master firmware downloaded. It said to put the Cortex in bootloader mode and we follwoed those instructions a few times. The right sequence of lights came on when done but the computer would still not recognize the Cortex for a firmware download.
I reinstalled the older version of the prolific driver too and had the same results. Went abck to the new one too.
Is there another program needing to be uninstalled too? Is there a proper sequence of operations?
