Boot Errors

: Some users report that older versions might not support "Loader" updates directly, requiring a specific boot file if the standard USB method fails.

Step 2: Copy the Firmware

• Extract the downloaded ZIP/RAR file.
• Inside, you will likely find one file named update.bin or MST999_H2.bin and sometimes a text file (readme.txt).
• Copy the .bin file directly to the root of the microSD card (not inside any folder).
