You need RT809 or vertyanov, change jtag_rst resistor from pulldown to pullup. Attach programmer to MEC jtag. Read, erase, rewrite (or just delete password section if you use vertyanov).

Hy everyone, my first thread. Has anyone succeeded in removing SVP stored in the MEC1663 chip in the T490 and T490s? I have a MEC Progammer but I don't know where to connect the wires. Also I undertand that if you erase the eeprom portion of the chip the serial number, mac address and other information are lost. One other forums someone said that if you solder a new chip the bios writes in it what it has too and the laptop works. I don't really want to begin soldering new BGA chips and destroying the laptop.
