Hi all

I have a Toshiba dynabook R730/B withe password problem

Board number is umt-sz2mv94v-0

First I burned the BIOS

Bios for Update is available at this address

You can download it by press Agree button
after download you must extract it
The package has several files

The two markup files we are discussing are
BIO007BT.COM is Bios file
EC73V160.BIN is EC file
for extract BIO007BT.COM to Bin you must use this script


And the original bios is in this address


after write bios password was still

I decided to burn the EC file

It is burned inside I/O chip part number "MEC1609"

The board have not any schematic so for jtag i need find the pins
I removed the chip after finding pins reballed it and installed it

you can find pinout file in this address

but when i erased EC chip and turn on toshiba again password was not gone

I think the password is also stored in a part of the BIOS that is not deleted during the BIOS update.

Can a friend help me with this?

any help or Opinion??
