    Turns out my successor was not able to update, so I've sat on 2024 january version this whole time. Now I understood the issue and got it updated. So ordering svod4 was pointless

                      There are some pieces to remove, compare with my file.

                      volinakis, you weren't far off, just forgot the checksum.

                            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.

                            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

                            Lenovo L14 gen 2 unlock with svod4
                            by 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?

                            Svod 4 reading emmc
                            by magicpc
                            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?
