Here is a review of the (and how it compares to later updates) for this hardware.
Before any development or "modding" begins, you must obtain a raw dump of the existing v1.0 firmware. Since official downloads for these OEM boards are rare, developers typically use an external SPI programmer (like the CH341A) to read the BIOS chip directly. ME Region Cleaning
Garbage characters at baud rates >460800. Cause: Clock calibration drift. Solution: Re-run the internal oscillator calibration via the command AT+CALIB (if supported) or switch to an external crystal oscillator.
