The error message "bootrom error wait for get please check stb uart receive google verified" typically appears on Android-based Set-Top Boxes (STB) during a failed boot process or an interrupted firmware flash. It indicates that the device's BootROM is stuck waiting for a command via the UART (Universal Asynchronous Receiver-Transmitter) serial interface that it cannot find or verify. Common Causes
Corrupted Bootloader: The primary boot software is damaged and cannot hand off the boot process to the operating system.
Hardware Handshake Failure: The device is looking for a specific "handshake" signal from a computer connected via a serial-to-USB adapter but is receiving no data.
Google Verified Boot (AVB) Failure: The "google verified" portion suggests that the Android Verified Boot process failed. The system detected that the firmware has been modified, or the digital signature does not match the hardware's security keys.
Power Issues: Insufficient power during a boot cycle can occasionally cause the BootROM to hang in this diagnostic state. Potential Solutions Hardware Reset: Unplug the power cable from the STB.
Press and hold the Reset button (often hidden inside the AV port or a small pinhole).
Plug the power back in while continuing to hold the button for 10–15 seconds to attempt a recovery boot. Reflash via USB Burning Tool:
For devices using Amlogic or Rockchip processors, you may need to use a PC-based burning tool (like Amlogic USB Burning Tool). Connect the STB to a PC using a USB Male-to-Male cable.
The "UART receive" error often clears once the tool successfully forces a new firmware image onto the device. Check Serial Connections:
If you are a developer or hobbyist using a UART adapter (TTL), ensure your TX/RX pins are not swapped and your baud rate is set correctly (usually 115200).
This error message is the device's way of saying, "I am listening for instructions on the serial line, but I hear nothing." Why "Google Verified" Matters
This specific string indicates that the device has locked bootloader security enabled. If you are trying to install a custom ROM or "unbrick" the device with unofficial software, the BootROM will reject the file because it lacks the required Google-authorized cryptographic signature. You must use the exact factory firmware (Stock ROM) intended for your specific hardware revision to bypass this check.
Do you have the brand and model number of your set-top box so I can look for the specific factory firmware or recovery tool? The error message "bootrom error wait for get
The error message "bootrom error wait for get please check stb uart receive google verified" typically appears when a Set-Top Box (STB) or Android TV box fails to communicate with a computer during a firmware upgrade or "unbricking" process. It indicates that the device's BootROM is waiting for a command signal (a "Get" request) over the Universal Asynchronous Receiver-Transmitter (UART) serial interface but is not receiving a valid response. Understanding the Error
This specific error string is often associated with tools like GXDownloader or similar flashing software used for STB chipsets (like Gsky V8 or Sunplus). Each part of the message points to a specific failure point:
BootROM Error: The low-level boot code built into the hardware has encountered a problem.
Wait for Get: The device is in a listening state, waiting for the computer to send the 0x7F (Get) command to initiate data transfer.
Please Check STB UART Receive: The device is not seeing any data on its RX (Receive) pin, which should be coming from your PC's TX (Transmit) pin.
Google Verified: This typically refers to a security check or a handshake requirement where the software expects the device to be recognized as a "verified" or authentic unit before proceeding. Common Causes
Incorrect Cable Connection: The most frequent cause is a faulty RS232 or USB-to-UART bridge connection. If TX and RX lines are swapped, the "Wait for Get" signal will never be received.
Driver Issues: The CH340 or RS232 driver on your PC might be outdated or incorrectly installed.
Voltage Mismatch: Most STBs operate on 3.3V TTL levels. Using a 5V adapter can cause communication errors or permanent damage.
Power Cycle Failure: Flashing tools often require you to press "Start" on the PC software before plugging in the power to the STB to catch the BootROM window. Step-by-Step Fixes
Verify Connections: Ensure your UART adapter's TX is connected to the STB's RX, and the RX is connected to the STB's TX. Check that you have a common ground (GND) between the device and the adapter.
Check COM Port Settings: Open your device manager to confirm the correct COM port is selected in your flashing software (e.g., GXDownloader or STM32CubeProgrammer). Perform a Power Cycle: Disconnect power from the STB. Click "Start" or "Connect" in your software tool. Be Careful with Advanced Procedures : When dealing
While the software says "waiting," plug the power back into the STB or hold the Reset button while plugging it in.
Google Verification/Account Fix: If the error occurs during a Google TV Streamer setup, try a factory reset to clear the "Verify it's you" loop.
Are you using a specific flashing tool like GXDownloader, or are you attempting to unbrick a specific brand of Android TV box?

Let's break down the possible causes and solutions for this error:
If you have more details about the device or specific steps you've taken, it might help in providing a more tailored solution.
The "bootrom error wait for get please check stb uart receive google verified" message is a low-level status or error string typically found in the Boot ROM (ROM) of Android-based Set-Top Boxes (STBs). It relates to the device's Verified Boot security feature Android Open Source Project Breakdown of the Error Components Boot ROM Error
: The error originates from the first code executed by the processor (the Boot ROM), which is hard-coded into the silicon and cannot be changed. Wait for Get / Check STB UART Receive
: The device is stuck in a low-level communication mode, waiting for a command or firmware image over the UART (Serial)
interface. This usually happens when the standard boot partition is corrupted or missing. Google Verified : This refers to Android Verified Boot (AVB)
. It is a security feature that uses cryptographic signatures to ensure that the software being loaded (the bootloader, kernel, etc.) is official and hasn't been tampered with. Android Open Source Project Why This Happens Tamper Detection
: If you attempted to flash custom firmware or a "rooted" ROM that is not digitally signed by the manufacturer or Google, the Verified Boot process will block it. Hardware Failure If you have more details about the device
: If the internal storage (eMMC) is failing, the Boot ROM cannot find a "verified" bootloader to hand off to, causing it to fall back to a waiting state. Corruption
: A failed over-the-air (OTA) update can break the "Chain of Trust," leaving the device unable to verify its next boot stage. Android Open Source Project Potential Fixes Reflash Original Firmware
: Use a PC and a specialized USB burning tool (often provided by chip manufacturers like Amlogic or Rockchip) to flash the official, signed firmware back onto the box. UART Connection : Advanced users can connect a USB-to-TTL adapter
to the device's internal UART pins to see the full console log and manually push commands to bypass the "Wait for Get" state. Hard Reset
: Some boxes have a hidden "reset" button inside the AV port or on the bottom. Holding this while powering on may force the box into a recovery mode where you can try a factory reset flashing tool is right for your specific TV box model? Verified Boot | Android Open Source Project
The most reliable fix according to aggregated search results and user reports (Oct 2024 – Apr 2025) is:
Shorting the eMMC pins while clicking "Start" + using a USB 2.0 port with a short cable.
If you still see "UART receive" after trying all 6 steps, your UART resistors (RXD/TXD) near the processor may be physically damaged or missing. In that case, you need a hardware serial TTL adapter (CH340) to manually send the update command.
