This is the right one, sorry for that

In the meantime, I tried to extract the .bin file from the official .exe with no success:
- unzipped --> no apparent binary candidate among the files
- Dell PFS Extract failed, so I assume it is not a PFS file
- ./Inspiron_7415_2-in-1_1.24.0.exe /writeromfile fails with error "Invalid H2=FFT-W parameters (-writeromfile)
- tried, out of curiosity to flash with NeoProgrammer the two files posted in this thread for the W25Q128FW (Mine is W25Q128JWSQ) .., and got an error:
"Current programmer: CH341 Green
22:56:01
Old protection Register: 01010001(0x51),
New protection Register: 01001100(0x4C),
Programming memory(verifying)... Main Memory
Verification error on address: 0x00000000, Device: 0xFA, Buffer: 0x82"
On a side node, I'm using the CH341 green version set to 1.8V.
So I will wait for your input.
Thanks again for the support!Comment

1. your bios backup has no volumes, means is corrupted.
2. how did you set to 1,8V CH341? You have to use an adapter for 1,8V, search for "1.8V adapter for ch341a" and you'll understand
3. Error is for bad or no contact of adapter with bios chipset terminals. Use ASProgrammer or Neo Programmer, not software came with CH341a
4. platform for bios is Insyde so use insyde IFD extractor for bios update package
5. you have attached bios image extracted from bios update, because your backup is corrupted i can't r ead DMI to transfer it.Attached Filesif you find these attachements useful please consider making a small donation to the site

Hi volinakis, thanks a lot for your support.
2. I have this version of CH341, which allows to set the voltage to 1.8, 2.5, 3.3 and 5 V: https://www.fruugo.de/ch341a-program...xoC4mEQAvD_BwE
3. I use Neo Programmer
I tried to flash the BIOS you provided, but got following error:
"Current programmer: CH341 Green
1:01:02
Old protection Register: 10000100(0x84),
New protection Register: 00001010(0x0A),
Programming memory(verifying)... Main Memory
Verification error on address: 0x00000000, Device: 0x04, Buffer: 0x02
Execution time: 00:00:00.038"
I am going to try with the adapter as well and let you know.
Edit: Second attempt worked well! Thank you!!!Comment

Hi,
My Dell Inspirion 7415 was doing some firmware update stuff and now it is asking me "Enter Current Password:". I don't have set one.
Can anyone help? I saw that some people have ansered with a 8 number password. How do you calculate this from the service tag?
Anyhow, I would like to have a similar password, which fits to my service tag.
Thanks!
SERVICE TAG: CB3FFG3
And is it possible to read out the original UEFI Firmware chip when it is in the system? (using a Dediprog SF100)
Do I need to switch the system to G3 (completely off, battery removed)? Or does it work in S5 mode?Last edited by ALLOUTBOUND; 04-02-2025, 11:44 AM.Comment

>Try new file , non DMI.
Thanks, this is the unchanged, "virgin" v1.27.0.
But I was hoping someone can tell me the password of my system.
When I use the new file, I guess that I will loose my Bitlocker key from TPM (let me assume that the Inspiron 7415 is using the AMD Firmware TPM, which stores its data into the SPI Flash ROM, and when a new, "virgin" UEFI FW is programmed, all the TPM data will be lost).
So any chance to get just the password?
Thanks!
By the way:

I can answer this now:
It is possible to read out the original UEFI Firmware chip when it is in the system. I just disconnected the battery, so the system was in the G3 (fully off) state.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... -
Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...
