Address 0h failing means:

: Ensure the exact chip model is selected in the software. Using a generic profile or a similar but incorrect model often leads to read/write errors.

: Using a test clip while the chip is still soldered to a motherboard can cause errors due to the circuit drawing power or grounding issues.

They noticed that the laptop’s CMOS battery was still connected (a CR2032 providing 3V). Even with the main battery removed, the CMOS battery was feeding VCC to the flash chip through the chipset’s standby rail. After removing the CMOS battery, the error disappeared, and the chip was read successfully.
