GS1000li problem during firmware update

I have a GS1000li, and during the attempt to update firmware, something went wrong. Now the unit doesn’t pass the boot screen, and it is constantly booting. If I plug it via USB into the laptop, it shows a USB drive. Using the Mooer Studio for GS1000, it prompts with “Device Disconnected.", Therefore, it doesn’t let me try to update the firmware again. Is there anything I can do to restore the unit?
