Hello two things UT6 chip is for Thunderbolt interface stay away.
Your BIOS is UC5 I did an ME clean of your BIOS you can program it and only that.
You also can't program an 8MB BIOS on a 16.8MB chip, that's not possible.
To upload something create a RAR or ZIP file then it works too.

Hello everyone.
Dell Latitude 7390 I5-8TH
LA-F312P Rev: 2.0 (A01)
s/n 3WJM5S2

I did some research and figured out which bios chip. So I performed the dump and very hopefully I wanted to write a bios test that you have already released in this thread.
But with desolation I see that they are all around 8Mb, while mine is 16Mb. So it doesn't seem very convenient to me to delete the 16Mb bios to write an 8Mb bios over it.
I read that: "EC/ME FW on 8Mb and Bios Region on 16Mb". So I'm wondering what should I do.
Thank you

Since I find it inconvenient for the forum to upload a 16mb file, it also seems like I don't have permission to upload a .bin file, maybe I should zip it?
I uploaded it online anyway

Bios dump: 7390.bk.bin

LEDs flash at startup, no screen.
I probably (if this is possible) damaged the bios chip because I forgot to remove the batteries.

In fact the chip is not automatically detected and even by putting a similar bios I cannot do the dump with Ch341A. (only 0).

I suspect that the Chip is burnt, I would like to buy a blank one on ebay, but I don't know which one to get for these two reasons:

1. chip model not perfectly readable (doesn't even seem to be winbond)

2. There are two chips with 8 pins (as visible in the photo)

That the real bios is on the opposite side from where the ram is?

Thanks for giving me help.

What kind of suffix do you have 8FC8 or E7A8
I'm guessing CPK95S2-E7A8 that doesn't work with 8FC8 that is unlocked via

Wrong chip.

Yes, i think it should be 16MByte chip
But this is from the laptop itself never change the chip

Im also confused why those 2 chip is only 1Mbyte

Couldnt find any chip labeled winbond on this mobo
Maybe any pointer & reference?
Thanks
