Well that's a shame my friend because no one can help you unlock your password, you have the model where the ME region or EC region was divided into an 8MB chip and the BIOS region was divided into a 16MB chip, for whatever reason.
In later models only a 32MB chip was installed.
It's not enough to just upload a BIOS file, it should be the right one.

Thanks.

Thanks.

You're right, I have a defective motherboard from a Dell 5400 notebook LA-894P there is only a 16MB BIOS chip UC5.
You don't have an 8MB BIOS chip, but your original BIOS file is damaged and the entire ME EC region is missing.

Hello,
I am completely new to bios flashing and I am kinda lost...
My situation is similar to the one above.. I do not have a chip in UC5 only one in UC6... I could desolder it to dump the data but the data file that I obtain is a 32 MB file... And I saw it should only be 8MB... What that means? Did I get the wrong chip ? Which software can I use in linux to be able to patch my BIOS file?

Thanks,
Jorge

Post the U6 dump,and the laptop service tag

Hello SMDFlea,
Thanks for the help! I have just attached to this message my BIOS dump. I greatly appreciate the help. I would also like to learn what was done to patch... Could you also pinpoint a place where I can learn how to perform the Hex Editing and some information about the different BIOS regions and why people have different sizes in the same laptop model ? Thanks!!

some laptops have 2 bios chipsets, main and EC. for bios regions use UEFITool. HxD has user guide, read it.
Also read BIOS guides, methods, resources and tools of this forum:
https://www.badcaps.net/forum/troubl...t=phoenix+bios
here is your modified bios, at 1st boot (let it run for 2 mins, it will restart several times with no image) press F1, write service tag, save (apply changes) then exit. 2nd boot press Alt+F to exit manufacturing mode.

thank you so much!
To make technical questions can be done on this forum or it is only for requests ? I am comparing the modified file with the original one to see what to change and I see you changed only 4 bytes from AA to 00... Is this right? how you determine which bytes have to be modified ?

Thank you!
