Important:
- This document is applicable to NovoTouch EK series, including NovoTouch EK2, EK3, and EK4 series.
- Each EK model has its own upgrade package. Please make sure you download the correct package for your model. Using a wrong package could make your NovoTouch unable to boot up.
Step-by-step instructions:
- The upgrade package is stored in a folder called “upgrade_811” / “upgrade_9950” / “upgrade_3588”. When you receive the firmware upgrade package, typically you need to unzip it first and then copy folder “upgrade_811” / “upgrade_9950” / “upgrade_3588”onto a USB disk. You should see the following file/folder structure on the USB disk. (The following picture shows how it looks for EK2 series.)
- For EK2 series, the folder should be “upgrade_811“
- For EK3 series, the folder should be “upgrade_9950“
- For EK4 series, the folder should be “upgrade_3588”

- Power down NovoTouch panel.
- Insert the USB disk into the USB port at the front panel of NovoTouch panel.
- Press-and-hold button POWER until the LED flashes red and blue quickly, indicating the upgrade process is started. Please do NOT remove the USB disk during this process.
- A progress bar is shown to display the completion percentage. Once it gets to 100%, the NovoTouch will restart automatically. During this first-time boot-up, it will take a bit longer to perform some additional post-processing.
- Once it fully boots into Android home screen, the firmware upgrade is completed. Now you can unplug the USB disk.
