  • New fallback logic for lost network shares (auto-reconnect with queue resume).

Step D: Prepare Your USB Drive

  • Use a USB 2.0 drive (8GB or less is best).
  • Format it to FAT32 (NTFS and exFAT are not recognized by the bootloader).
  • Copy the update file to the root directory (not inside a folder).
  • Rename the file if instructed by the distributor (often to update.bin or upgrade.pkg). Leave it as-is if no instructions specify.
