What happens during the update

The display will compare the version you are trying to install with the already-installed version. When they are the same, it wont install any firmware update. In some cases, it might be necessary to install another version of the firmware first to achieve your desired installed version.

First, the display will update and when it is finished, the screen will reboot and upgrade MCU automatically. The whole update will take about 15 minutes to complete.
