I would suggest using a more recent flashrom version like v1.2 just in case
there are relevant bugfixes.

So dediprog sets its voltage to 1.8V...

... but this chip is a 3.3V part! Just in case, double-check that the model
on the chip matches what flashrom detected (the "." means any character,
like W25Q64FV"). You can also turn on the board and measure the voltage
between flash chip pins 8 (VCC) and 4 (GND).

In any case, W25Q64.V is a 3.3V part, and W25Q64.W is a 1.8V part. Note the
different "V" and "W" endings.

Hi,

here just some general information/advice:

Use the latest flashrom version (current version 1.2: 
https://www.flashrom.org/Flashrom/1.2 )

For chip handling issues:
https://www.flashrom.org/Board_Testing_HOWTO

For electrical issues:
Do read operation several times and check for equality.
Touch the cable/wires before starting a new read operation in 
order to find out if the contacts are good.
If all reads give you the same file there shouldn´t be any problem at 
electrical level.
If you get diffs between the files you have an electrical problem -> check 
contacts, use as short cables/wires as possible and try a lower frequency (if 
programmer supports this; do not overvalue the impact of frequency on total 
programming time, for some programmers most of the time is lost on other stages 
like usb communication etc. ). Check again with several read runs.

Regards,

Simon

Hello, I would like to put a message I keep on getting.
The bios nowadays is not working fine any longer, and the laptop doesn't boot, 
clearly.

#=#=#=#=#=#=#=#=
Erase/write done.
Verifying flash... FAILED at 0x! Expected=0x5a, Found=0x00, failed byte 
count from 0x-0x007f: 0x10c3
Your flash chip is in an unknown state.
#=#=#=#=#=#=#=#=

I would be very happy to get some kind of help, and since I am a newbie, it 
would be great if you feel ready even just to address me to the most relevant 
web pages.
The job is focused on flashing a 16 pin mx bios chip on a lenovo laptop model 
x200, for the use of a specific firmware called LibreBoot.

Many thanks again,

Sandro

Hello this is my output when trying to flash..

Does Incomplete/failed Command Receive Device string plays a role on
the error of verification?
I cannot flash back the original bios contents at the moment on my board.
