need bios dump dell latitude 5420 (cpu 11th)

[mojito12]

Hello!

I have a 5420 with service tag BKS39K3. i5 11th gen. Does anyone have a bios dump for it?
Thanks in advance

YES it's worth it

I've already tried flashing a much older bios, it didn't help. I uploaded the current bios, it works, but every time I reboot, the TPM is OFF!

I can't read the 25RH256CXIQ chip, the TL-866II Plus reader detects an unknown chip. I can extract another chip from the wrong board, but what should I write in it? I think this is the end.

Don't do that.

[Echoo]

Sorry!

Good day!

I have a Dell 5420, if I turn on the TPM, save the BIOS, then enter after rebooting, the TPM switch is OFF again! I can't turn it on! Is it possible to fix this? Is it worth reading / uploading the BIOS?

I have a CH341 programmer, but it is not listed when I search for my BIOS chip. Then, I tried to use detect with no results. I manually searched XMC XM25RH128CHIN chip doesn't appear in the list. I used CH341 2.2 version/ NEO Prog and AS programmer, but non of the programmers has this chip in the listing

Thank you for the reply
I downloaded the app ASProgramme 2.1.2, and as per your Picture attachment,t I can see the chip in the listing, but the software ASProgramme won't recognise it. My CH341(black), so it won't work, but I know that the programmer CH341 does work fine

Advice from the expert will be much appreciated.

Are you using an adapter board or a clip.
