Hi, i got a locked Elitebook 840 G3, unsoldered the IC (winbond 25q128fvpq) flashed it with CH341A and unlocked it with RCunlocker. I successfully soldered it back in, but now i got a "Authentication Failed" error when trying to enter Bios.
The Board Number is: 6070B0883401 REV: 1.01 A01
The Laptop SN# is 5CG7242DC8
Here is the orginal Bios dump as well as the unlocked one:...Leave a comment:
