GoKawiilYouTuber details $10 flash-programmer method to unlock BIOS-locked ThinkPads
A YouTube channel called Rebooted by Hileeq published a tutorial showing how to bypass supervisor passwords on Lenovo ThinkPads with 4th- to 8th-generation Intel CPUs using a $10 CH341A flash programmer and a second PC. The method builds on earlier work shared by Victor Voinea and Knucklegrumble, and later analyzed academically by researcher Mark Juvan, to read and modify the EEPROM/SPI flash chip that stores the password.
