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

Re: Dell e5470 adp70 la-c831p bios bin
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

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... -
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...
