Flashing the firmware

These steps will guide you through the process of flashing your touchscreen's firmware.

T5UID1

This process will require a micro SD card with a capacity under 8GB (larger micro SD cards might not work for this purpose).

Download the T5UID1_*.tar.gz archive that matches your touchscreen resolution from the latest release.
Extract the content of the archive. You should now have a folder called DWIN_SET, which we'll use later.
Optional - If you are coming from a different firmware, it is recommended to replace the T5UID1.CFG file in the DWIN_SET folder with the one available here.

Start by formatting your micro SD card. Select FAT32 for the file system and 4096 bytes sector size (these parameters are strictly required for the procedure to work).
Copy the DWIN_SET folder from the archive you previously downloaded to the root of your micro SD card.
Unmount and unplug your micro SD card.

⚠️ You must use the DWIN_SET folder from the release archive, not the repository ⚠️

Turn off and unplug your printer (both power and USB).
You will need to access the micro SD slot on the back of the touchscreen (not the one that could be on your mainboard). If necessary, open the printer to be able to access this slot.
Insert the micro SD card into the slot.
Plug the printer's power cable back (and only the power cable) and turn the printer on.
After a few second, the screen's background will turn blue and the flashing procedure will begin.
Do not cut power to the printer while the flashing procedure is running!
When the procedure ends, you will be back on the page with a blue background. There will be an END message at the top and you'll be presented with a summary of what was flashed.
At this point, you can turn your printer back off, remove the micro SD card from the touchscreen and reassemble your printer if you had to disassemble it previously.
