Hey, 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.

before you start the procedure read the bios eeprom and save it you might need it at the end
1do not power on your svod yet
2plug you ribbon 30x0.5 to the left of the keyboard connector
3test pin with testeur if it beep go to next stage
4 open svod software select 1.8v
5 now plug your svod
6 select nuvoton
7 plug charger on the board/laptop
8 press read id
9 select 256k
10 read nuvoton

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? -
Hello, is svod 4 able to read emmc? Do I need a special board or is it enough to solder into the pinout and insert the other side of the cables into the programmer? somehow especially set the svod?
