Hi Guys,
I thought I write you a tutorial on how to remove your bios password from your lenovo x390 yoga.
Steps:
1. Get an EC programmer and read the EC firmware.
2. Back up your working EC file !!! (on this modell EC stores all hardware infos and you cannot replace it with others)
3. In your EC firmware file find all of these ranges with a hex editor and replace them with 00:
!!!!!! IMPORTANT THAT YOU ONLY MODIFIED THE SPECIFIED RANGES AND NO MORE.
(I have used HxD Hex editor FREE for this since I found that it is easy to replace ranges)
0x36000 - 0x3604F
0x36080 - 0x360CF
0x36100 - 0x3614F
0x36180 - 0x361CF
0x36200 - 0x3624F
0x36280 - 0x362CF
0x36300 - 0x3634F
0x36380 - 0x363CF
0x36400 - 0x3644F
0x36480 - 0x364CF
0x36500 - 0x3654F
0x36580 - 0x365CF
0x36600 - 0x3664F
0x36680 - 0x366CF
4. Save the modified EC firmware and write it back to the laptop.
Laptop should boot and there should be no BIOS password anymore.
This tutorial is made after several days of knowledge gathering and work. Please Use it wisely.
