Hello,
I have a Lenovo Ideapad 3 14ADA05 with a unknown bios password that a want to remove

I pulled the bin file off the bios chip but I can't seem to find where the password is located to translate it from a hex editor.
Any help would be greatly appreciated. Thanks!

Thank you peste but it doesn't work, password is still here.

I have found Password string in binary file (offset 0x00310529) and set to 0x00 somme bytes inspired by another patch I found on the site but it didn't change anything. In the example I found there were two Passwords to patch, for me only once.

1. download https://www.badcaps.net/filedata/fetch?id=3647825
2. extract file
3. name the extracted bin file E8Crisis.bin
4. drop the file named E8Crisis.bin on fat32 usb drive formatted mbr or gpt try both for most laptops start with mbr format then try gpt
5. turn off laptop
6. unplug charger
7. insert usb
8. press and hold Fn+R
9. plug charger while holding Fn+R a red light should start blinking on the left side of the laptop
10. while holding Fn+R press power button to turn on the laptop
11.if everything goes as instructed your screen will go back and a bios flashing process will show up on it
12. release Fn+R wait a few minutes for the process to end and pc will go back to normal
13. once done and booted to windows install the latest bios available on lenovo website
14 load default setting in bios
