¶ 2. U disk read error, UI update failed!
This pop-up appears when the USB drive is removed during a firmware update. Please reinsert the USB drive and attempt the firmware upgrade again.

When saving the sliced file to the USB drive, wait for the transfer to complete before removing the USB drive to avoid file corruption.
