Downgrade MC4-R Firmware Version to 3.003.0035 or Earlier

IMPORTANT:

Do not perform this procedure unless it is recommended by Crestron Technical Support.

The MC4-R's built-in infiNET EX radio firmware was upgraded with the release of Crestron Home version 3.004.0071 and is not backwards compatible. If it is necessary to downgrade the MC4-R control processor firmware from 3.004.0071 or later to 3.003.0035 or earlier, downgrade the infiNET EX radio firmware prior to downgrading control processor firmware.

To downgrade the MC4-R control processor firmware, follow these steps:

NOTES:

  • Transfer files between the PC and the Crestron Home processor using an FTP client.
  • To issue console commands, use the Text Console tool in Crestron Toolbox™ software.
  1. Download the PUF file containing the desired MC4-R control processor firmware (3.003.0035 or earlier) and then transfer it to the MC4-R's /Firmware folder.

  2. Identify the radio stacks that are supported and record the index number for version 5810. To view the radio stacks, enter the following command:

    rfsystem

    The console displays the following:

    upload NCP app image with the gateway builtin version

    RFSYSTEM [STACK INDEX]

    List of Radio Stacks Supported

    Index Version

    --------------

    [1] 5810

    [2] 6230

    System is currently running version 6230

  3. Downgrade the infiNET EX radio firmware to version 5810. To downgrade, enter the following command:

    rfsystem [index]

    NOTE: It may take several minutes for the process to complete.

  4. Verify that the radio firmware was successfully downgraded to version 5810. To verify, enter the following command:

    rfsystem

    If the downgrade is successful, the console displays the following:

    System is currently running version 5810

    NOTE: Crestron Home version 3.003.0035 and earlier does not display the version number when the rfsystem command is used.

  5. Do not restart the MC4-R control processor prior to downgrading the processor firmware. If the processor restarts, the firmware downgrade reverts while the control processor boots.
  6. Downgrade the MC4-R control processor firmware to version 3.003.0035 or earlier. To downgrade, enter the following command:
