Greetings,
Wanna unlock mine BIOS (LENOVO-J6ET58WW(2.03)).
Files: Original and Backup
Backup done by Universal BIOS Backup ToolKit 2.0. As I can find in DUMP (was done by phoenixtool266) locking stored in 79E0EDD7-9D1D-4F41-AE1A-F896169E5216_1028.ROM.

Also as I found on forum I'll need SOIC8 clip and SPI-programmer couse mine BIOS is rewrite protected, as programmer we can use arduino for ex., as I know, and also can bought clip for it. 

Can you assist me in unlocking and BIOS patching for further programming 

So.. I've got CH341A Programmer and SOIC-8 clip, and after I disassembled the laptop, I could find only 2 memory chips, the rest, as I understand it, are transistors. Those chips are: winbond 25Q32FVSIG 1353 and winbond 25Q64FVSIG 1403.
Is it right one
