HP 840 g10 bios

[Duckie-Electronics]

Oh yes, main from post # 120 and updated EC on post # 156. Flashed both.

Hey rex98 and lapfix, I have confirmed process on second device. The process I used is what is noted in post # 120

1. Take full BCU config dump
2. Flash EC chip with EC_NVRAM_CLEAR.BIN from post # 156
3. Flash SPI Main with MAIN CLEAN UNLOCKED.bin from post # 120
4. first boot press f10 apply factory defaults and restart.
5. 2nd boot reset security settings to defaults and exit.
6. use BCU and put your original DMI. I had to add the following:

Product Name
Serial Number
SKU Number
System Board CT Number
Feature Byte
Build ID
HBMA Factory MAC Address
HBMA System MAC Address
Cirrus Discrete Amp Calibration Data

Managed to solve the issue. I modified your EC.bin provided in post # 120 and cleared NVRAM ActiveRegn.

This time, instead of the EC recovery screen, it threw the "Entering MPM" and was able to F10.

Password now gone. You are a legend rex98.

Probably best to verify attached before use.

hi bro. can i ask how to modify EC in case? i have HP G9 12th same problem. thankyou
