Improper operations during firmware update may cause malfunction to the M3 Pro! Please read the following guidance carefully before proceeding.

Update procedures:

1. It is recommended to choose a micro SD card with FAT32 file system. If the update is not successful, please try a card of 32GB capacity or under, formatting it with the M3 Pro (back up data on the card first). And then copy the M3 Pro.zip file package to it and attempt to update again.
2. Ensure the M3 Pro is sufficiently charged (preferably full-charged) before the update to prevent power failure during the update process.
