Buy a 1.8V/3.3V voltage adapter board for your CH341A, or use a resistor voltage divider on the MISO/MOSI lines (2.2kΩ and 3.3kΩ).
Best practices and recommendations
To fix this, open the downloaded .bin file inside Intel Flash Image Tool (FIT), replace the ME region with a clean, unconfigured repository file from Intel, and compile the final output image. Step 3: Transfer DMI Data (Serial Numbers and Windows Keys)
To trigger the recovery, turn off the laptop completely. Press and hold the on the keyboard, then press the Power Button while still holding the other keys. After a few seconds, you can release the Power button but continue holding Windows + B until you see the BIOS recovery screen appear. If successful, the system should read the BIN file and automatically flash the recovery image. This method is often the first line of defense when the system has a partial POST but cannot boot completely.
Remove the laptop battery and disconnect the AC power adapter.
Must be properly cleaned or configured for the 640 G2 to prevent rapid shutdowns or sleep issues.

This method relies on the system's internal boot block being functional. If the corruption is deep enough (like a bad ME region) or the boot block itself is damaged, the laptop will never look for the USB drive, and the recovery hotkey sequence will produce no result.
Crucial Step: Click after the write process completes. The software compares the data residing on the chip sector-by-sector against the source file. If verification fails, desolder the chip from the board and program it directly on an adapter board, as motherboard components can pull down data lines during in-circuit operations. Post-Flash Initialization Procedure
What specific or blink codes is your laptop showing?
To use this file, you cannot simply copy it to a USB drive. You need hardware tools:
Potentially yes. If you flash a generic "clean" BIN file from the internet, you may lose the embedded Windows license key (MSDM) stored in the ACPI table. If you have a backup of your original BIOS, you can re-inject the key later.
Disconnect all power sources, including the main laptop battery and the CR2032 CMOS coin-cell battery.
Once writing is complete, click to ensure the data written to the chip matches the file perfectly. Post-Flashing and First Boot
