Use specialized tools designed for your specific processor (like Amlogic USB Burning Tool or Rockchip FactoryTool) rather than generic UART terminals. These tools know how to bypass the security handshake. Hardware Troubleshooting Table

For devices with a physical reset button or AV port, inserting a toothpick into the AV port (pressing an internal switch) while powering on may also trigger MaskROM mode.

Different SoCs and boot stages use different default serial communication speeds. The BootROM typically operates at very specific baud rates. For some Amlogic devices, failing to use a UART adapter that supports 921600 baud can result in garbled or entirely absent console output. Use specialized tools designed for your specific processor
