Hello forum,

I have a Dell 3440 213247-1 motherboard with a corrupted BIOS. I found one on the forum that allowed it to power on, but the screen stays black (lit) and it restarts. I’m attaching the faulty BIOS.

Service tag: 6834fs3

Thank you very much.

Hi This is an English ONLY Forum. Take some time to Read the rules > RULES UPDATE for BIOS requests/offers *AVOID BANNING, READ BEFORE POSTING* - Badcaps
That said, Try this file it should for you I think. If it doesn't I'll send you another

This BIOS has a password. Can you provide a way to clear or decrypt the password for me?

The file above didn't work.

Try this file next and see if it works
If not check whether you still have the 0001 prefix or if it changed to something else (for example 6LR3754-8FC8)

[vennercell]

The first file displayed video but still retained the admin password, while the other one wouldn't boot the laptop. Notebook 3440

[Sparo]

Flash it again and check your soldering. Also give it some time to boot it may take a bit long

It ended up with this code: 6lr3754-8fc8

Good I knew it's going to change to 8CF8 now post a new backup of your BIOS chip let's unlock it
Don't post the one you already posted, make a new backup (Or use the patcher to unlock it yourself)

[vennercell]

I redid the entire process, applied the patch, and when I connected to the internet it was blocked again, asking me to contact the IT company. I believe this happened right after I added the service tag that still links it to the previous company.

Post the BIOS dump I'll unlock it for You
Upload the new BIOS backup not the old one with the 0001 suffix

Oh sorry guys this is my old bios file please

Service Tag "transcribed" typed out: 6N6BKX3

Flash this file, First boot F2 enter BIOS Settings and Write the Service Tag, Save and Reboot
Second boot ALT+F to exit manufacturer mode, You can enter BIOS again to factory reset the settings.

Hi You need to Post the Service Tag with every request. Also attach files (as RAR) directly to your post
> RULES UPDATE for BIOS requests/offers *AVOID BANNING, READ BEFORE POSTING* - Badcaps
Additionally, what suffix is shown when you try to unlock the BIOS settings? 8FC8? 0001?
