This is the most comprehensive repository for Ameco/Micov/MXTronics firmware . You can find tools like MW8209_6208E_v1.1.2.5 or UTools_V10.7 here.

If you've encountered a "write-protected" error, a capacity mismatch, or an SD card that simply won't open, you may need a firmware flash. MXTronics (often associated with or Micov controllers) is a common brand in the world of generic and branded flash storage. When these cards fail, standard formatting tools often fail with them.

Do you have the numbers from a tool like ChipGenius so I can help you find the exact firmware version? Ameco / Micov / MXTronics - USBDev.ru

Using the wrong firmware version (e.g., flashing MW8219 firmware onto an MW8259 chip) can permanently disable the card.
