Hello, your bios is corrupted. Read again.Comment

Oh no, that was verified before rewriting. Can I take a dump from different machine but same model?Comment

Yes, if you clean the ME region it works.
You can also build a new one.
There is no information such as Windows Key Service Tag stored in your BIOS file.Comment

Hello rex98, thank you for your correction, I have already compared yours and my BIOF file and of course found that our two files are identical.
It was too tedious for me to comment on it because we both don't know what skills the user has, how good their soldering skills are or the like.
I think what most people forget is to do the steps described in the Dell article.

Because the manipulated patch resets everything to the beginning.
So I always do it as described by Dell and have no problems.

Thanks for the reply Markus1741 I am 99.99% sure with that solder hehehe but I will still resolder the chip. They are not that hard compared to mobile phone chips. In case my BIOS backup file was corrupted, is there any way to fix the problem?

Oops, I once compared your original uploaded file with a file from me without a PW and in my opinion it is defective.
There are too many inconsistencies listed.
The second picture should show yours with PW on the left and mine without PW on the right.
Now you need a new BIOS file, I can build a new one, but from experience it's unlikely that that will solve the problem.
Second choice is a ME region cleaned file, Dell is not that picky.Attached Filesif you find these attachements useful please consider making a small donation to the site

Hello, this BIOS is mine, I'm pretty sure it didn't have a password.
Try it otherwise we will patch it again.

Just try NeoProgrammer, your programmer software can't handle the chip.
I would also invest in a T48 or RT809F or RT809H programmer, they come with their own software.Comment

Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.
so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, π π π ... -
I am trying to remove the BIOS password for a Dell Latitude 5430 motherboard LA-L591P. So far I think that I have located the BIOS chip but NeoProgrammer says that is detects 3 chips. I have attached the dump from each one. Are any of these the BIOS file? Service Tag: 1DMC1T3. If nyone knows the exact location of the bios chip as well I would greatly appreciate it...
