by 2elwHey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:
STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.

by x16Hi,
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?-
