                    send us a clear picture of the board, a broad view of the whole EC chip and it's surrounding resistors, hopefully someone can help you locate that resistor

                                          it can be done with autopatcher and replacing EfiSystem volume with one extracted from bios update. I did few in this way, the problem I encountered was bios chipset, if it is MX25L256 replace with W25Q256 - I don't know why MX chipsets does not work with patched file. So, when I see there is an MX chipset I jut read it and I use a winbond chipset for patched file and and after unlocking I put back MX chipset untouched.
