Re: HP BIOS unlock tool
Hi guys,
i need some help finding the 2. BIOS Chip also the EC one on HP Elitebook 830 G6.
The Big one with 32 MB i got already. On the other side of the board, there are 2 Chips:
MX25L12873F (I think this is the correct one cause 128Mbit = 16MB)
And the Winbond W25Q80DV (I don't think this one cause 8 Mbit = 1 MB)
But i am not 100% sure. Could you please help? Which is the correct one?
Thank youComment

Re: HP BIOS unlock tool
Not correct
It's just that it seems a little bit hit-n-miss for now. I've done a few here when I have been 100% certain it works on that machine.
A small part of first padding on 16MB needs to be cleared.
Just in case backup your 32MB and then try this.Last edited by RethoricalCheese; 07-30-2021, 02:02 AM.Comment

Re: HP BIOS unlock tool
Surprise, surprise, that's new approach, nothing to do with the old method - very interesting, for which models is it applicable/tested?. BTW how far did it go with the HPU v.2?

Re: HP BIOS unlock tool
Many thanks
Ok seen
but information seem encrypted?
a xor or others swap bytes can be use for see may be ?
what information is written in this part?
Just 16mb is enough now or always do both for bypass?Last edited by Maxpower3; 07-30-2021, 05:02 PM.Comment

Re: HP BIOS unlock tool
Just continue doing it the old and tested way. My way is actually older but the problem is that I don't get any newer machines to test enough to get it working on all machines. Thatswhy I haven't published new version yet. It would just complicate things.
On the ones I do get, I always only modify 16MB chip.
HP doesn't use xor sadly. So decrypting wouldn't be viable.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,... -
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)... -

Hello to all of you! I need help with a BIOS file.
The BIOS chip is fried on my Asus F542UN laptop, and I bought a new chip that needs programming. I have a CH341a programmer but I need a .bin BIOS file. On Asus support page the firmware has another extension, .310 and from reading on this forum I understand that that file is not complete BIOS.
So, in short I need the "complete" BIOS .bin file to flash on the new chip. Another issue is that on back of the case the label says F542UN but on the sticker on the motherboard it's X542UN. -
Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer...
