Swap out legacy tools for open-source, community-maintained alternatives:
If you receive this error, follow these steps in order to resolve it: Step 1: Clean and Check the Clip
This is a leading cause. Certain versions of the original CH341A software are known to have compatibility issues with particular flash memory chips. Users frequently report that newer versions (e.g., v1.30, v1.34) fail verification, while older, more stable versions like v1.18 work perfectly for write operations.
This message indicates that the write process was unsuccessful, often leaving the chip partially written or with corrupted data, resulting in a bricked device. What Causes the "Disagreement" Error? This message indicates that the write process was
Features an updated database for modern flash chips and handles verification sequences with clear error logging.
: Ensure the red wire on the ribbon cable aligns with Pin 1 on both the clip and the CH341A PCB.
The popular black or white clips used with the CH341A are notoriously flaky. : Ensure the red wire on the ribbon
: Loose tester clips, oxidation on chip legs, or long cables corrupting the SPI signal.
You are looking at a disagreement. The chip says one thing; the programmer says another. Who is lying?
Sometimes providing power to the motherboard (without actually turning it on) can help stabilize the circuit, although this is controversial among repairers. Step 5: Desolder the Chip (The Last Resort) oxidation on chip legs
: Supplying 5V to a 3.3V or 1.8V chip, which destabilizes data transfer or permanently damages the silicon.
For a quick reference, here are the most effective fixes for the "disagreement" error:
