When software tricks fail, you must read the password directly from the chip. The Unowhy Y13 uses a Winbond 25Q series SPI flash chip soldered to the motherboard. This chip contains the BIOS, the serial number, and the password hash.

If the laptop is legally yours (purchased at a school surplus auction or you are the IT admin), you can request the Unowhy Y13 Bios Password via their official support portal. You will need: Open a terminal and run: sudo flashrom -p

Without institutional ownership, Unowhy will refuse to provide the password, citing security policies.

When all software methods fail, you must go hardware. This requires technical skill, a $10 CH341A programmer, and steady hands. Do this twice and compare the MD5 hashes

The Unowhy Y13 stores calibration data (like the Wi-Fi MAC address and audio codec settings) in the same SPI flash you just overwrote. If you flashed a dump from a different laptop, those values are misaligned. You need to extract the "Factory" region from your original dump (even if password-locked) and merge it with a clean BIOS. Use UEFITool for this.

Result: On some older firmware versions, this bypasses the password entirely and boots to Windows. If it works, immediately go into Windows and flash a BIOS update from the Unowhy support site to overwrite the password section.
