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, 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,... -
Hi, I hope some one has some advice for me. I searched the forums but didn't see anything relevant. I acquired two identical Dell 9010 Mid Tower computers from a business office upgrade (they were going to throw them out). Both of them have the same motherboard (00F82W). One of them works flawlessly. The other one had a corrupted BIOS. I tried flashing numerous main BIOS and EC files from the internet, but none of them worked. I decided to copy the main BIOS and EC from the working 9010 computer and successfully flashed the corrupted BIOS. This got the computer able to boot again and run norm...04-23-2025, 04:30 PM -
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, 😅😅😅... -
Hi folks,
I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)
Steps I took:- Read BIOS with CH341a, verified hash twice
