Update EC on ThinkCentre m715q (1st Gen)

February 2, 2022

I spent a lot of time trying to figure out how to update the embedded controller in the Lenovo ThinkCentre m715q, not realizing that it was part of the autoexec.bat file:

ifu315.exe M11CT11A.bin 64 /R0 
flash2.exe imageM11.rom /bb /rsmb /ncb

Apparently, you need to load the ec image into SPI Flash with ifu315, and then it will get updated when you update the BIOS via flash2.

Hope this helps someone in the future.
