Hi there,

I have a Dell Latitude 7410 with a corrupted BIOS (I assume).

Motherboard: LA-J261P Rev 1.0
Service Tag: 3LRHQ73

BIOS Chip I'm working with is a GD25Q20CT

Attached is the bad bin.

I've tried writing other binaries to the new chips I have, but the files have all been the wrong size.

I need a good bin for that chip so I can get the laptop working again. Would love it to have no BIOS password.

I'm new to BIOS stuff, so I don't know much and might be off in my understanding of things. Any help would be greatly appreciated. Thank you so much!

The GD25Q20CT is 256KB. You backed up the wrong chip. Flash that backup you made back onto it, then leave it alone... .Look for the real bios chip. Don`t,don`t,don`t flash anything to any chip until you verify it is the bios chip,and the backup is good.

Quote of the day: assumption is the mother of all mistakes

Thanks so much for your response. Any advice on how to identify which one of the chips is the BIOS chip?

Based on this statement of volatility from Dell, it looks like the one I pulled off (UV32) was the HDMI controller. And it looks like the BIOS chip is the UE1 (MEC5107K-D4-LJ), which is on the bottom of the board. I found a schematic of the board here, and it looks like that's a BGA chip. If that's the case, that's fine. I just bought a CH341A, so I would clearly need something else since that only deals with 24 and 25 series chips.

There are references in the schematics to UC5 (25B256DYIG) being a Flash ROM chip, and when I look at eBay listings for the BIOS chip for this MoBo, it looks like it might be that one.

But there are various GD25 series chips on the board as well.

I apologize, I promise I'm not trying to be a moron. This is just my first time really doing this kind of board-level repair. Thanks for your help.

25B256DYIG

Thank you so much, SMDFlea! You're the best.

I was able to dump the BIOS, and I've attached it here. Is this correct?

Two notes: I actually have two of these motherboards. One with a broken BIOS (I think--it won't POST), the other with a locked BIOS. I don't know which one this is. But they're both the same mobo model.

I'm not sure what the issue is with the BIOS. Is there like a standard firmware I can flash to it? Thanks for all your help.
