Dell Latitude 5520 3FE2 Bios password Unlock Request (TGL SouthPeak15) bios

[kevin_kim]

How did you guys pull out the bios image? In windows using a software or using a tool like CH341A. To me it seems like 5520's bios chip is bigger, can't use the clip to mount to it. How do you pull it out?

Friends, I have a Dell Latitude with a BIOS password. I downloaded the latest BIOS version here, but it didn't detect the NVMe SSDs. I'm attaching my backup to see if you can help me remove the password. I don't have the serial number because they only brought me the motherboard and a picture. I'll try to provide all the information. Please help!

Wrote your file to a new blank chip and it worked like a charm.
Thank you

Always follow this order when flashing chips: Erase → Write → Verify
In any case, I'm glad you got it sorted out. You're welcome, and see you on the forum!
