Bios Mods -The Best BIOS Update and Modification Source

I am very new, what will I need to provide?

Hi, I've got a problem with my Dell Inspiron 3721 asking me the current password whatever I try to do at start up.

I've been told that I should flash my Bios but with 3721A14.exe (https://www.dell.com/support/home/fr/fr/...erId=70H05) I downloaded from Dell support site it is impossible to get the Rom and hdr files (even with Uniextract)

Can you help me so I can flash my Bios using a USB stick following d3n7s procedure found on this forum.

Best regards
