Your provided serial does not match any of the dumps provided...in fact the two dumps are from different laptops...anyways,
here you got two dumps (EC+BIOS) but you need to use BCU tool to enter factory data ... from your provided bios content is this:

Thank you so much for your swift response. I appreciate it so much.
So after flash the EC & Bios you provide, I get a steady white light with 11 amber then 6 amber blinking then restart.
Please kindly help me in anyway you can. Thank youComment

That dumps worked for me on several 840 G5 laptops.
First , you must check all components near the EC and BIOS chips to ensure you have not blow out any little resistor and second sometimes it takes a long time to boot for the first time after flashing both EC and BIOS and I mean even up to 5-10 minutes with several restarts.

Hi, experts. I have an HP Elitebook 840 G5 with a locked bios password. Is there a method to remove the password without an EC chip? I can successfully remove passwords using patchers and RC unlockers, but I'd like to learn how to remove passwords using the main bios chip. I tried the HP unlocker, which created the unlock file but did not work. I attempted to delete the bios password manually using Hex editor and the Usercred method, but it did not work. I am posting the 32MB bios password locked.

Hi guys,
If someone would be able to provide some expertise, I'd be very grateful.
BIOS Corruption - Cause
So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC.... -
Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello,
I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.
I assume the BIOS update failed, so I searched for the BIOS chip.
I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.
However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR
