EC Dump is in the BIOS. search at 300000h. if necessary, cut out from the BIOS. hex editor can be cut out.
Here is an example of the beginning of the EC firmware in the BIOS.

p.s.
If we don’t know how, send the BIOS from the board to me in a private message (ЛС). I'll cut it out.

Thanks for the hint..

Here is my original bios + EC pulled from it (Starting Address=300000, End=31FFFF, Length=20000 / 128KB)

is everything right ?

P.S I have a bunch of BXA versions instead of CXA, do you think it should work ?

1. It’s better not to make the BIOS public here. there is a windows key. I wrote what to send in a private message. Better remove the file.

may not work. may not work correctly. It’s better to put what was standing. after all, the revision version of BXA is lower than CXA.
Here's the service firmware to try. cut out EC. bios from here. Thank slavashoot

I can't edit my post, I've sent a report but still not answered..

the BXA version made the "ITE Busy" on the SVOD3, replaced with a new CXA version and filled with my dump but still no reaction to the power button..

EC_PWROK = 0v
traced to SYS_SHDN# = 0.4v
traced to Thermal Sensor PU3002 which was shorted, removed and +5VPCU appeared but no +3VPCU
3V_LDO became 0.6v, found a knocked-out capacitor PC6022, installed and 3V_LDO became 3.3v again and +3VPCU appeared
EC_PWROK = 3v and the board started :co_ol:

PU3002 = TMP708AIDBVR
any analogues ??

TMP708AIDBVR TEMPERATURE SWITCH RESISTOR
