Hi all, after several attempt, I finally got a working CH341 Pro working USB device. Now I'm able to read dump the BIOS

When I verify the image (800G6_EC_RCunlocked.BIN found on this forum) I receive "[B]Buffer data does not match SPI chip![/B]". I tried different programmer but the message is the same. Anyway, I removed the password but I see at the boot the HP Message:

"HP Endpoint Security Controller Problem"
[ATTACH=JSON]{"data-align":"none","data-size":"thumb","data-attachmentid":3448284}[/ATTACH]...

the issue is that. I'm facing a lot of issue with the micro clamp connector: the yellow led "RUN" on the usb key sometime disappear completely while I'm dumping. Probably I have to change clamp and use another method...

I tried to enable and disable it, no success

well, I bought different cables and now I successfully dumped the old bios, so it was just a cable and connector stuff. If I put the file into the RCUnlocker it says: "Missing unlockable Content"
I noticed that during the writing of the Unlocked Image (fond in this forum) I received an alert from the Programmer saying it has hit an error, so I clicked continue and the Programmer stuck.

BTW now I successfully installed the new unlocked version! [B]hooray[/B]!!! The HP now give me the ability to enter into the BIOS and Security settings but I have a message at the beginning:...

a little progress here: I finally received the programmer but when I connect it to the motherboard, I receive this message:
[CODE]
[B]IC Not Responding[/B]
[/CODE]

only once I got the message while using the ASprogrammer 2.1.0.13...I was able to read but not to write

any idea? thanks a lot !

ps: the current is 3.3, just checked it out ...

Ok, now the programmer has arrived and I did probably some mistakes because now I see the message "HP Endpoint Security Controller Problem: There is a problem with the HP Endpoint Security Controller on the unit, please contact HP Inc to have the unit serviced"

what can I do now?

thanks

sorry, cross posted after searching other informations...I'm waiting for the USB programmer, and so tomorrow I should dump/flash it back and keep you posted. Thanks again...and BTW, ehy, the post now is on top

cheers

hi there! I'm an "old" Italian geek, started in 1986 when I was a kid....now I found this forum because a recent buy on Ebay, I have to remove the bios password from an hp elitedesk....I'm always curios on these type of things and flashing BIOS is my first time in more than almost 40 years ! BTW I'll use this unit as a third proxmox node for my home lab. Thanks to all!!

hi, I'm in a rabbit hole: I have the "OK" from the RCUnlocker_v_1_0 and so I loaded the 16MB "800G6_EC_RCunlocked_unlocked.BIN" inside the NeoProgrammer 2.2.0.10. If I click "Detect" I only see:

[CODE]Connecting Error CH341 (Not found)
Connecting Error CH341 (Not found)
Connecting Error CH341 (Not found)
IC not responding[/CODE]

I'm running Windows 11 directly on top of the HP Elitedesk G6 800, do I have to desolder ?

what can I do now?

Thank you !!!!!
