Step 1: Download the update file Make sure to choose "Save File". You can also save it directly to the SD card. If you didn't save it directly, copy the update file to the SD card. When the update file is the only file on the SD card, the preparation is complete. Do not change the name of the update file or extract it. Leave it as it is (Ellipal_titanplus_v3.12.1)
NOTE: For Mac OS, your browser preferences (Safari, Chrome etc) must be set to "stop automatically extracting downloaded zip files" to properly extract the updated file. It will only work if it is a zip file.
Mac users are advised to download the upgrade file using Chrome instead of Safari to avoid potential upgrade issues.
