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

Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS
Hello everyone,
I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.
This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.
I have opened the laptop and identified the main BIOS chip... -
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...
