    Product Firmware Update Failure

    This article applies to most Makeblock products that can be connected to mBlock software, such as mBot, Ultimate 2.0, Ranger, etc. The following troubleshooting steps take Ranger as an example.

     

    1. Issue Description

    After clicking Update Firmware on the mBlock page, the progress bar does not change at all or stops before the progress bar completes, and the software page displays the error “firmware update failed”.

     

    2. Possible Causes

    1. The product and software are connected via a bluetooth adapter or bluetooth.
    2. Operation errors, such as selecting the wrong device extension, or ticking the “Show all connectable devices” checkbox when connecting a device.
    3. The power switch on the motherboard is not turned on.
    4. mBlock 5 software bug or version reason
    5. Serial port driver problem
    6. Motherboard failure

     

    3. Troubleshooting Steps

    1. Make sure to use the official USB cable to connect the mBlock and operate the update. If you connect via other methods, the firmware update is not supported.
    2. Incorrect device selection does not actually affect the connection of the product, but the firmware update will fail. So make sure the device extension is selected correctly. If there is a green arrow in the upper right corner of the device extension prompting an update, please update the plugin before adding the extension. In addition, do not tick the “Show all connectable devices” box on the connection page.
    1. The product's Power Switch needs to be turned on. Lack of this step will directly cause the firmware update to fail.
    2. Make sure you are using the latest version of the mBlock software: https://mblock.cc/pages/downloads and switch to the web version to test if the update is successful: https://ide.mblock.cc/ 
    1. Enter your computer's device manager and check whether the CH340 driver is displayed normally. If the port is not displayed or there is a yellow warning mark in front of it, you can re-download the serial port driver: https://www.wch-ic.com/downloads/CH341SER_ZIP.html
    2. If the above steps have been troubleshooted correctly and the problem persists, you can consider replacing the motherboard with a new one. Please contact the support team for parts replacement involved.
