HP 800 G6 Deskop Mini - Endpoint Security Controller Problem

[Voyager65]

Hi all,
I got a used HP and see this well known HP Endpoint Security Problem Screen. Someone seems to have removed the password and reflashed the bios with (maybe) a wrong serial etc.. I was able to read and write with my programmer a new bios onto it - same problem. I tried a downgrade, same.
I did password removal wir rcunlocker on several other machines without any problem. But this one is/was killed before. Appreciate any help.

Thanks hoaca388,

Both with the same error.

This is EC files, upload a bios file, it from another chip.

I tried to read the 32MB Chip with HP Software, but I'm not sure if this can be used by you. If you know a good way to dump the HP Bios by software, please let me know or point me to a source where I can read about it.
I just ordered a soic16 clip in case, that this file is not useful for you. With this, I can use my programmer to dump the bios ic.

Attached what I did with the HP tool

Thank you very much. It worked great. I was able to put my information with the HP BIOS Configuration Tool into the BIOS.
But I can‘t set "Born date" and "UUID". Is there any way to do this? Would be great to have my old system back 1:1.
I have all the data from the old state saved via the configuration tool as text file.

Hi all,

I got a HP EliteDesk 800 G6 DM with a locked admin password, I attempted this method to reset https://blog.rhysgoodwin.com/it/hp-e...sword-removal/ which was successful even though the guide had Gigadevice chip and my EC chip was Winbond (I did verify the pinouts were same).

However after password is reset, I'm now getting a "HP EndPoint Security Controller Problem" screen every boot, similar to this guide: https://www.indiafix.in/p/how-to-res...-security.html, I'm currently able to set a 15 sec auto-bypass in BIOS and the machine works perfectly otherwise.

Not sure what I did wrong as the main BIOS was not touched/updated by me at all.

Main 32MB bios dump is attached, thank you so much BadCaps!

Try and Update.

Hi, I downloaded the file attached and ran a quick diff in HxD with my original read1.zip - the files appear identical? Also ran a SHA-1 hash and both files give same result Bios Cracker can you confirm, thank you!
