HP Elitebook 8460p Product information is not valid

[Hirador]

HI!
On my elitebook 8460p, the Product name, Product serial number, Product SKU and system board serial number are missing without any reason. I've tryed many nbdmifit tool version from without any luck. When i run the correct dmitool, i enter correct values from the laptop but the it gives me an error and rebooting the system gives "machine in not in commited state"

Also tried BCU, without any error, but the bios remain in the same state

After a bit of research, I managed to understand that to make this changes, I need to set the pc in commited state and unlock the MPM but I can't find the right SMC (tried many that comes with the dmi tools)

Other researches brought me here, where I've learnt that by dumping the bios in a bin file, it can be modified and re flashed in some ways.

I expect someone to request my dumped bios, but I only managed to dump a Rom file of my bios via a universal dumper tool found on this forum. If you could guide me in this process of dumping the bios, so I can give it to you and then flash it back, I would gladly follow your instructions

Thanks in advice

You can use mazzif elitebook/probook unlock tool to program new DMI information on 8460p. I found it to be the easiest way.

Tried it, selected the re-progam option, filled everything but at the end after the succesfully reprogrammed message, nothing appens after reboot. Same invalid information

Try clearing uuid first if there was an option for that. If not, just use shotgun and then try reprogramming.

Tried it, without any luck. I think that to modify effectivelly anything i need to have MPM/Commited state unlocked

Post your bios backup .

Re: HP Elitebook 8460p Product information is not valid

Here you have, inside you will find both Rom and bin file format of the bios backup (they might be identical, just different extension), And the missing information notified by the computer. Inside the info you will find another information about the UUID, (i report it here, i think it is kind of broken and don't have a label inside the laptop with it)
I really would like to thank you in advice for the support

It should be possible to read/write bios on this model using a software programmer like fptw or similar.

2.4KB means there is something wrong It should be in MB, not KB.
