Board doesn't boot if VCORE stays at 1.12V.
I supposed wou already understood that.
Could be a simple bad resistor, until bad CPU.
Re-check all the job did on the board.
Be sure all SPI Bus Series Termination resistors and their traces are good.
Did you note droping voltage at pins 5 & 6 of U6100?

"Replaces u7400 and r7402,03, the CPUIMVP_TONA voltage 0.67V , I found too low."
Not low at all, really.
Be sure you've soldered correct values for R7402/03.
Check other job you did on the board too.
