Re: Flash HP 450 G5 using Arduino - wrong file size

Thank you RethoricalCheese,

700000 is decimal or hex? At both positions in dump.bin I can't see something similar to the content of HP bin files.

I searched for "Flash Image Tool", but I can't find the right version. I understand that the version I must use depends on the mainboard chipset.

It seems that this notebook uses Kaby Lake-U.
I tried v8, v9, v10 and v11 from [url]https://winraid.level1techs.com/t/intel-converged-security-management-engine-drivers-firmware-and-tools-2-15/30719[/url]....

Re: Flash HP 450 G5 using Arduino - wrong file size

The mainboard doesn't boot, so I expected to have a broken dump.
What I'm interested in is a way to convert HP provided bios file(s) and reflash it.

I'm trying to flash an HP Probook 450 G5 (2XY63EA) BIOS using Arduino.
It's the first time I try this procedure so maybe I'm missing something stupid.

I've been able to unsolder bios chip (Winbond W25Q128JV) and wire it up to Arduino.
I also dumped it succesfully ([B]dump.bin[/B]).

Now I'm having a hard time trying to reflash it, because the bios file I downloaded from HP has the wrong size.

I downloaded bios from HP ([url]https://ftp.hp.com/pub/softpaq/sp103501-104000/sp103710.exe[/url]).

When launched, the executable extracts...
