Lenovo L14 gen 2 unlock with svod4

[x16]

Hi,

I have a problem with a Lenovo L14 gen 2 (intel) with Nuvoton npce68b.
I connected my svod4 with a 32pin cable to the keyboard connector. Ground is also connected and power for the mainboard. I can read the Nuvoton ID, but the dump is always empty. Does anyone have an idea?

This one works in bypass, right?

Thank you, but i already read the both threads yesterday. And i tried bypassing method 4 hours. But didn't work. I tried shorting Pin 26, 27, 28 or 1 shorting to ground. I tried on backlight on at the moment when Logo apears. Nothing! If i short too long or at wrong timinig it freezes, but never got error like fan error or something.

Pin 26, 27, 28 or 1 shorting to ground.

probably a writing error

126-127-128 or 1

intel too, amd works more easily. wait for someone else's response to see if it succeeded.
it was to see if you had the info

11th gen ?? Espi this one, don't try the bypass in this case
what is the ref

Yes sorry it was 126, 127, 128 or 1

And thank you for the links.


General:

I normally unlock mec16xx chips with the SVOD4. I have little experience with Nuvoton. Am I perhaps doing something wrong? Do I have to solder a resistor? Because I can read the Nuvoton ID, but neither the content nor can I delete the chip.


EDIT:
It works now. The trick is, only connect a (better full charged) battery. Do not connect usb-c power.
