An incorrect baud rate will trigger a "Wait for Get" failure. Adjust your flashing tool or terminal program (like PuTTY or MTK Flash Tool) to the standard specifications for certified Android STBs:
The "BootROM Error: Wait for Get" is rarely a sign of a "bricked" hardware unit but rather a protocol timeout. By ensuring electrical continuity, proper voltage levels, and correct software sequencing, users can typically bypass this error and proceed with firmware restoration or Google TV Streamer recovery
: Ensure the RS232/USB-to-Serial driver (e.g., CP210x, CH340, or PL2303) is correctly installed on your PC. An incorrect baud rate will trigger a "Wait for Get" failure
: Completely disconnect power from the STB, press and hold the recovery button (if applicable), and then apply power while the flashing software is in the "Waiting" or "Start" state. Check Driver Installation : Verify the serial adapter is recognized in the Windows Device Manager and that the COM port matches the software settings. Baud Rate Adjustment
: Many recovery tools require you to press Start on the PC first, then power on the STB to catch the BootROM's initial "request" window. : Completely disconnect power from the STB, press
| ☐ | Verified UART adapter functions on a known-working device | |☐| Confirmed correct TX→RX wiring with no loose connections | |☐| Tested multiple baud rates (115200, 921600) in serial terminal | |☐| Successfully entered MaskROM/BootROM mode via shorting or reset button | |☐| Installed proper drivers (Amlogic USB Burning Tool drivers v2.1.7/2.2.1 recommended) | |☐| Disabled Windows driver signature enforcement temporarily | |☐| Ran flashing tool as administrator | |☐| Confirmed firmware matches exact device model and SoC version | |☐| Tried alternative USB port (preferably motherboard USB 2.0) and a different cable | |☐| Considered professional flash programmer service as last resort |
If you are reading this, you are likely staring at a black screen or a frozen logo on your Android TV Box (STB), accompanied by a cryptic error message on your PC terminal or screen: | ☐ | Verified UART adapter functions on
Try swapping TX and RX wires to see if the "wait ROM request" advances. :
For Rockchip-based devices (RK3328, RK3318, RK3228), use FactoryTool or AndroidTool instead of Amlogic tools. The shorting process and MaskROM detection will be similar.
: This could imply that the issue is related to Google's verification process, possibly indicating a problem with booting a Google-verified operating system.
BootROM chips only listen for incoming serial data during a fraction of a second immediately following power initialization. Completely unplug the power cable from your Set-Top Box.
