Step 1: Prepare

• Before we upgrade to the new firmware, we need to be sure that we are on the latest 1.0.6 from Creality
• Skip the below steps if your LCD and Motherboard are on 1.0.6.
• Goto website https://www.creality.com/pages/download-ender-3-v3-se and download Ender-3 V3 SE_HWCR4NS200320C13_SWV1.0.6_GD303.zip
• LCD Display firmware update：
• Format the MicroSD card on the computer side, and select 4096 for the allocation unit size.
• Put the file "TJC_SET" into the MicroSD card.
• Turn off the printer and Insert the MicroSD card into the card slot on the left side of the screen.
• Reboot and wait for the update to finish.
• After finishing the update, remove the TF card and delete the files inside.
• Mainboard firmware update:
• Format the SD card on the computer side, and select 4096 for the allocation unit size.
• Put the firmware file "Ender-3 V3 SE_HWCR4NS200320C13_SWV1.0.6_GD303_20230915.bin" into the root directory of SD card.
• Rename the Ender-3 V3 SE_HWCR4NS200320C13_SWV1.0.6_GD303_20230915.bin to 1.0.6.bin

Step 2: New Firmware

• Go to https://github.com/navaismo/Ender-3V3-SE/tree/main/Firmware
• Download the latest, I typically choose 128Kbps file
• All these are for Octoprint, as well, and, work fine as a standalone too.
• Download the zip file and extract
• Rename the file to 1.0.9.7.9d.bin and paste it on a formatted SD card
• Note we do not need to update LCD firmware.

Step 3: Upgrading

• There should be no other file on the SD card.
• Before you upgrade, note the old firmware version
• Wait for 5 minutes before you start the printer and insert the SD with Firmware
• After boot, check the firmware version has changed to a new version

Step 4: Conclusion

You also have the option to fine-tune the config files to your needs... there are tons of tutorials on the topic. Hope you liked this article and share any feedback
