Hi,
I am trying to do this GitHub - hamishcoleman/thinkpad-ec: Infrastructure for examining and patching Thinkpad embedded controller firmware to enable usage for t420 keyboard change for my t430.
I have CBET4000 Heads-v1.4-6-gd46488a
but thinkpad-ec github page says i need BIOS 2.81 (G1ETC1WW) and EC 1.13 (G1HT35WW)
Does that mean there is no way for me to ec flash it unless I’m willing to go back to G1ETC1WW?
