Hi
I have an HP 8470p with W25Q128BVFG bios chip. Is there a way to reset the password without dumping the chip using a programmer?
Also all the instructions are for the 8 pins chips. This 16 pins chip is a bit different. Would you please help me here? thank youLeave a comment:

Hello,
yhank you for your help but I have a problem.
the keyboard is out of order (I did not know that "detail") so I did desold and resold twice but at the second time, I swipe one or two components (I'm sure for one, this circle alone, next the white arrow).
I think it was resistors.
Do you have the resistance of them?
EDIT> I found what I need on the forum :-)
Very nice forum here!Attached FilesLeave a comment:

Hello all. I followed the link as best I could. Flashed the bios again. Laptop is fully functional but very slow startup and HP logo sign. I am not sure what file to use if EC needs to be repaired. All laptop info looks correct in bios. I assume that is ME area? I'm confused as this is a bin right from here and every comment says no issues
Any help would be great.Leave a comment:

Hey guys. Need help. So I used HpUnlocker on my functional 840 G2 laptop. I saved the orig dump. Ran it through the program and flashed it back with verify. Now laptop has black screen and caps light flashing. Tried multiple times. Then I downloaded HP bios from site and installed through holding "B" and it fixed it BUT now it says
Custom logo image greater than 1024x760
Warning Machine is not in committed state
Good news is there is no password
I have attached both
I'm at a loss and hopefully someone can help
FYI other than probably my mistakes this tool is Amazing
I seem to be posting in the wrong places lately so I hope as this has everything to do with HpUnlocker it's rightLeave a 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 all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76
Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R... -
Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...
