Open the Amlogic BootcardMaker utility on your PC.
Select your MicroSD card drive letter, open your stock ROM image file, and extract the u-boot.bin file.
The error manifests differently depending on the tool being used, but the underlying issue is the same:
Ensure you are using the exact stock ROM for your specific device model. If you are using a generic image, try a "clone" image from a similar device (like Tanix TX3 Max for S905W chips). Insufficient Power:

The u-boot.bin itself is sometimes the root cause.

Try the USB port closest to the Power/DC jack, as it often has a more direct connection to the board.
If the device is bricked and won't enter flash mode, you may need to disassemble it and short the eMMC pins to force the SOC into Mask ROM mode for a clean flash.

partition after writing it to the device's internal memory (eMMC). The DTB is essential as it tells the hardware how to communicate with its various components (Wi-Fi, RAM, CPU). CoreELEC Forums Common Causes Checksum Mismatch:
A compiled data structure that describes the hardware layout (CPU, memory, GPIOs, peripherals) to the operating system. Without the correct DTB, the kernel cannot communicate with the hardware.
Corrupted internal storage (eMMC/NAND) or bad sectors can cause verification to fail when the tool tries to read back the written data.
