The "bootrom error wait for get" message proves that your set-top box's processing core is still functional and responsive. It is a sign of a software-bricked device rather than a physically destroyed chip. By carefully validating your TX/RX serial wiring, initializing your flashing utilities before powering on the board, and using the Mask ROM short-circuit technique if necessary, you can push past this boot loop and successfully flash clean firmware back onto your device.
) must be held "High" during a reset to enter the bootloader. Connection Interferences The "bootrom error wait for get" message proves
When an embedded device or STB boots into a flashing or restoration mode, its internal BootROM runs a small software sequence. It opens up its hardware UART ports and waits for a specific byte configuration—often a GET command (such as 0x7F used in common microcontrollers)—from an external software flasher. ) must be held "High" during a reset to enter the bootloader
