This error indicates a communication breakdown between the PC and the device's BootROM during a recovery attempt. In essence, when you see this error, it means the device is "alive and listening" on its UART port but is waiting for a signal from your PC that isn't being sent or received properly.

Below is a based on the likely scenario:
Try a different power adapter with the exact same voltage and higher or equal amperage ( Reboot: Plug in only the power. Phase 2: Forced USB Burning (Most Common Fix)
| Token | Meaning | |-------|---------| | bootrom error | BootROM exception or state timeout | | wait for get | BootROM is waiting for a “get” command (e.g., get or go in Amlogic, Rockchip, or similar BootROM protocols) | | please check stb uart receive | Suggests UART RX line may be faulty or no host is sending data | | google | Possibly the expected token or part of a secure boot challenge |
The error is a fallback mechanism. The BootROM is designed to look for bootable code on a device’s internal storage (e.g., eMMC flash). If it fails to find a valid bootloader there, it falls back to other boot modes, including UART. This automatic fallback happens to prevent the device from becoming completely unusable. However, if the PC fails to respond correctly on the UART interface at this stage, this error appears.
The timing of power application is crucial. Some users find success by connecting the USB cable before launching the tool, while others need to connect it after.
