If you are stuck in the MM311 firmware update process for more than 5 minutes, please try following instructions to resolve it.
NOTE: Please make sure to plug the dongle in the PC and the MM311 is connected during the steps.
Press “Abort” to exit the update process or open the “Task Manager” and close the task “RENEW”.
Exit MasterPlus+ Software first, and re-open the MasterPlus+ Software.
It will automatically read the current firmware version and pop out the window to tell you to update the firmware. Press “Install” to update the firmware again.
Please follow the update instructions. After both mouse and dongle firmware are updated, the MM311 is ready for normal use. If it doesn’t, please contact [email protected] for more help.
