I have a Dell XPS 7590 here aswell with a corrupted Bios. Laptop powers on and after a few seconds powers itself down again. I managed to extract the bios and Uefitool seems to recognize the data.
Service Tag of this laptop is: FJ1YK63 (Laptop model P56F003).
Corrupted bios attached in the zip file. Would be amazing if someone could help me get a working bios image for this laptop again!Comment

My Dell XPS 15 7590 has been bricked due to bios update.
min attempting to reflash the bios chip with a c341a programmer.
I realised I don’t have the bin file for this bios.
When I read the chips on the motherboard. Both come up with all 0’s in the software.
One chip on the motherboard is a 25Q80DV
the other is a 25Q80EW
can anyone please guide me towards finding the correct size file to write over the chips and can anyone give me information as to why they are currently both all 0’s.
the file I could save from those chips were just over 1MB.

Thread merged. The 25Q80 chips are not the bios, they are for firmware. If you havn`t erased those chips leave them alone ! ,if you have then post those backups here so we can check them .Next,look for the correct bios chip,it should have something like 25Q256 or a 256 as the part number. The supplied CH341A software is shit,to put it mildly. Use NeoProgrammer software,you`ll find it on the forum if you search.When you do find the right bios chip make a few backups and compare them to make sure they`re the same, then post one of those backups here, don`t flash any other bios or erase the chip, its imperative you make a good backup.
Also,you must post the laptop service tag -> https://www.badcaps.net/forum/troubl...before-postingComment

Hello!
Thank you for the response.
This is the only chip I can find with something related to 256 written on it. But the other letters I can't find when looking on Neoprogrammer or Asprogrammer. (Neo also pops up saying ic not responding). Would this be the bios chip?

Hello,
My Dell XPS 15 7590 has a corrupted BIOS following a BIOS update.
Service Tag: 9TM38Y2
Model: XPS 15 7590
Here is the original corrupted BIOS (extracted twice and compared with "certutil -hashfile" to be sure they are the same)
AsProgrammer couldn't recognize the chip (25B256DYIG) so I input the size from the other bios files shared here manually (33554432), hope this will do.
Would be amazing if someone could help me get a working bios
Thank you so much!

Hello,
I am troubleshooting a Dell XPS 12 with motherboard 9Q23 (Compal LA-8821P) that failed during a Windows 10 update. The system powered off abruptly and never booted again. Initial behaviour- No display at any time (internal or external)
- Power button would immediately shut the system off
- System auto-powers when AC adapter is connected (battery removed)
- Beep code: 3 beeps – pause – 3 beeps (continuous)
- Fan never spins

I have a Dell XPS-15 (9520) with the LA-L402P motherboard. It seems to have bricked itself after a common BIOS-Firmware upgrade. Now, it just shows BIOS screen for a few seconds before turning-itself back Off (and doesn't seem to be fully Posting). I've done these many times before with no problems.
I was hoping to please have my own-thread to work-through this (hopefully successful) repair as a whole. Apart from the possible need to have a BIOS-dump fixed-up, I have a feeling I'm going to have other questions. This includes using my new XGecu-T76 for the first time (should be here... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Sorry for the long story. I have a Dell Latitude 5530 (i7) laptop (South Peak 15 MLK MB DDR4 203102-1 FK8VG$JA) with an admin BIOS password that I want to remove. Service Tag: HYKFPT3. Other than that the laptop worked OK.
I found a CH341A Black and went looking for the BIOS chip on the motherboard. After trying to read one chip that was a firmware chip but not the BIOS I think I found the BIOS chip labeled Winbond 25Q256JVEN. Altogether I think I found 4 different firmware chips in the laptop. The BIOS chip is a WSON8 6x8. I used the CH341A, NeoProgrammer, and a cheap pogo pin clip...
