I did this fix successfully with the Teclast X80 Pro.
FWIW – It worked for me with a non-powered USB hub.
Other notes:
When extracting the RARs, you choose to overwrite files. Also, extract the contents of the RAR folder with Chinese to the root of the USB drive, not the folder with Chinese writing itself. The only extra info that would be great would be a specific list of the partitions you can delete, and can’t.
Thanks for all of the help! This saved a LOT of stress, hassle, and time.
