3. The Firmware Distribution Ecosystem

6. Common Errors & Troubleshooting

• Device not detected by PC: reinstall USB drivers; try different cable/USB port; use powered USB hub.
• “Parameter/board mismatch” or bootloop: ensure firmware board name matches; reflash correct firmware.
• Stuck at logo: try factory reset from recovery; reflash full firmware image including bootloader.
• Flash fails mid‑process: retry, use different USB port/cable, or try SD card method.
• Hard brick (no lights/boot): possible UART recovery or JTAG; seek hardware‑flashing service.

4.2 Mask ROM Mode

When a device is bricked, it must be forced into "Mask ROM" mode. This is achieved by grounding specific pins on the PCB (often requiring disassembly) or by pressing a concealed recovery button while powering on. In this state, the device awaits a command from the host PC to receive a new bootloader and firmware. mxq pro 4k rk3228a firmware download
