You might see a green checkmark "100%" but still get this error. That is the "patched" part—SP Flash Tool tricks the CPU into skipping the RAM check long enough to write the Preloader , but fails when trying to write system or vendor .
For many 2026-era security patches (especially Xiaomi/MT6765 devices), you must manually select a custom DA file (like DA_6765_6785_6768_6873_6885_6853.bin ) in the "Download-Agent" field of the SP Flash Tool .
Sometimes, the error occurs because the tool is trying to verify the RAM integrity before flashing, which fails due to driver timing. Changing the mode often bypasses this check.
The tool is telling you that it detected the exception and applied a software workaround (a patch) to try to bypass the RAM check. The fact that you see this error means the patch failed . The RAM is still unresponsive.
Imagine your phone is a high-security vault. You have the "key" (the firmware), but when you try to unlock it, the vault's internal security system (the Download Agent) realizes the key was made for a slightly different model of the same lock. In many cases, such as with the Redmi 9A (dandelion)
