[REQUEST] Bios password removal

[madalin.vladescu]

hello everyone. i`m sorry if it is not the right thread but could not find any more suitable. i`m having a Lenovo Yoga 13 20175 with password on BIOS and SSD drive. i got it from a pawn shop for a bargain. can you help me unlock it?

i have found a dump for the exact chip Winbond 25q64cv and flashed on it. i got it working but i still have the SSD locked and now the serial number and model name of the laptop are showing INVALID.

in the attachment are 3 files: LENOVO_ORIGINAL_66CN55WW.ROM (original bios from Lenovo Website), BACKUP_LOCKED.BIN (the bios that was on the laptop, locked with password and also password protected SSD) and the last one DUMP_FOUND_Yoga13.BIN (which i found after a google search).

if there is a way to extract the passwords from the second file, that would be great. any help would be great appreciated!



many THANKS!!
