HP EliteBook **70 Series BIOS Password Reset [Util Test]

hi,

did you enable the kernel-modules for SPI?

Code:

sudo modprobe spi_bcm2835 && sudo modprobe spidev

if that fails use the older version :

Code:

sudo modprobe spi_bcm2708 && sudo modprobe spidev

check if the modules are running:

Code:

lsmod

if you are running raspbian, you must first enable SPI using the config:

Code:

sudo raspi-config

and then activate the kernel-modules using modprobe as shown above.

SPI is listed under "Interfacing Options" and can be enabled from there.
cheers

Hi Mazzif,

first of all i want to thank you for your great instruction and support. After several tries with the raspberry i could not read/detect the flashrom.
Then i tried it with an eeprom/flashrom programmer and everything was fine. After Programming the flashrom Bios was possible to use.

On one laptop everything is working properly and there are no issues but on the other one i have the problem that the "ME state is in recovery mode" is always coming while booting.

Do you have an idea how to solve? Could you please tell me the steps after programming the flashrom when the factory mode is on. I think i made a mistake there..

Thanks and Br,
Truthmi

 

Hi Mazzif

I've tried your method using the padding file, on an elitebook revolve 810 g2.
This laptop have 2 eeproms. One winbond W25Q128FV (16Mb) and one other CFeon EN25QH16(2Mb).
I'm using an Elnec BeeProg for reading and writing the eeproms.
I've used the padding file on the 16Mb eeprom,and indeed it removed all of info (serial,sku,etc,etc) and when i turned the notebook on, it appears the message "MPM 1 of 10", and next a white screen stating product information not valid and showing the serial, the sku, etc .... all blanked out.So far so good.... but the next screen is EC MPM and system MPM mismatch, and stating that the system needs to restore system information and even i've stopped the process, rebooted and tried do boot from usb and network, it is always going to the same screen of ec mpm and system mpm mismatch.
Without any other option, i let the system information be restored, and once finished and booted, i have another screen saying "The embedded controller MUD data is not valid while MPM is locked.Please unlock MPM and lock again to capture valid MUD data".And this is the message that made me want to unlock MPM.
I booted to windows, run wndmifit, but unfortunatelly the MPM is already locked.
Any help ??

Thanks

 

You just remove password not dmi information.
