Re: Dell e5470 adp70 la-c831p bios bin
when restarting the pc freezes with black screen even before showing the dell logo. I have to turn off, unplug and try again
if I hold down the power button when the pc is frozen, the fan runs at maximum for a few seconds, then turns offLast edited by drdom; 03-06-2021, 09:17 AM.Comment

I just managed to complete the installation in raid mode, in ahci mode after the preliminary phase the pc restarts and freezes on the spinning dots. I have 2 e5470 with the same problem.
the bios that i flashed takes a long time to display the dell logoComment

Re: Dell e5470 adp70 la-c831p bios bin
try this bios.Based on your service tag number this one has AMT ,and the spec is a H cpu. This bios will work for the other with the same spec. If the other has a U cpu youll need a different bios for that .Comment

Try the bios again at post #8 and disable AMT in bios settings. Are you using the genuine dell wifi card that came with the machine ?Comment

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 -
Hey everyone,
I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.
The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.
When I check the BIOS using the F12 menu Flash... -
Hi,
Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate... -
So, i kinda spend significant ammount of the last couple of days trying to flash a new bios, and or unlocking the current bios password with little to no results.
The whole thing started with it being the 8fc8 bios, i found the tools to unlock that but i needed a bios dump. So i pursued that, im at a point where i dessoudered the chip, and succesfully soudered it to the ch341, dumped whatever was on it.
However, the tools supposed to unlock the 8fc8 say that there is no 8fc8 hex inside. And when i followed diffrent tutorials to just flash a new bios onto the chip i got stuck on the...
