Hi everyone,
I'm working on removing an administrative BIOS lock (Supervisor/Admin Password) on a laptop.
The board has three SPI flash chips:
- W25Q64FV (main BIOS)
- W25Q32FV (EC/TPM)
- W25X10CL (configuration)
I was able to read the dump from the W25Q64FV chip, CRC32 = 0x3DE23E27.
The dump contains protection that needs to be removed.
If anyone has a clean or unlocked BIOS dump for W25Q64FV, I’d really appreciate it!
I’m also happy to share my dump for comparison if needed.
Laptop model: [please specify, e.g.... -
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 :

Hey guys, I have an "ASUS TUF Gaming A15 FA506NF (2021)" that's locked with a UEFI password, I need to reprogram the BIOS chip but can't find a clean ".bin" file for this specific model, I've tried the official BIOS updates from ASUS support page, but they're 32MB updaters that don't extract to a usable 2MB .bin file for direct chip programming.
What I currently have available:
- Model: FA506NF (2021)
- BIOS chip: GD25LQ16 (16Mbit/2MB)
- Tools: CH341A programmer ready to use
Does anyone have either a clean 2MB .bin dump of this model,... -
Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....
