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 you

Upload main 32MB dump too.
The same applies for Mrnixdorf.
There is no way to do the unlock with just 16MB file.

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.

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?

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?

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.
