The dumped binary (BIN) file is run through the Lenovo AutoPatcher executable or patch script. This script automatically identifies the password hash/tamper protection data in the BIOS and overwrites it.
Drag and drop your confirmed .bin dump file directly into the extracted lenovo_autopatcher folder. Open a Command Prompt or Terminal inside that folder directory and enter: autopatch original_backup1.bin Use code with caution.
Use your USB programmer to write the original_bios_PATCHED.bin file back onto the physical motherboard chip. lenovo autopatcher
The patching computer requires a Python interpreter and the UEFIReplace binary tool to process the image modification.
The technician uses an SPI flasher (like a CH341A programmer) and a clamp to read and dump the firmware directly from the BIOS chip on the motherboard. The dumped binary (BIN) file is run through
The (often credited to the user Knuckle Grumble on forums like Badcaps) is a specialized Python-based utility used to remove Supervisor Passwords from Lenovo ThinkPad BIOS chips. It works by modifying a "dump" of the laptop's BIOS firmware to bypass the security check during the next boot. Technical Summary
In a nutshell, the script works by taking a backup (a "dump") of your computer's BIOS chip, automatically patching the firmware data to remove the supervisor password, and then allowing you to flash this modified BIOS back to your device. It is designed to work on older Lenovo devices, typically up to the 8th generation of Intel processors. Open a Command Prompt or Terminal inside that
Unlocking a BIOS via an autopatcher requires interacting directly with the physical motherboard components. You cannot run this patcher from inside standard Windows or Linux setups without extracting the chip data first.
Python script is run against the BIOS backup to generate a "patched" version of the file. : The patched file is written back to the BIOS chip.
: An SOIC8 or SOIC16 test clip connects the programmer to the pins of the motherboard chip without requiring desoldering.
