            I was wondering if i can simply replace the nuvoton npce288ga0dx chip from another board, would that also work?

                Could you provide a proper config string for LAR-2? The board has a 36-pin socket with 1 pin from the left. Why need to change to right?
                Thank you
                I red firmware from Nuvoton chip but can't find data on address 36000h

                  Lenovo Thinkpad L13 Yoga Gen2

                  I downloaded EC (npce68apa0dx) firmware from LAR-2 motherboard
                  but can't find an area to clear the supervisor's password.
                  Could you help me, please?

                      Thank you! It works.
                      The first time was an alarming sound and message Security CRC Bad but after BIOS defaulted became good.
                      The supervisor's password is gone.

                      Unlock Lenovo L13 Gen 2 20VJ, LAR-2 MB, EC NPCE68BPA1DX with SVOD 4:

                      1. set programmer as in photo. Power up motherboard and hit "Read ID" . I got Device ID: 1F20E20F. After that hit " config NOVUTON" and chose 384K and check NPCE68xxx
                      2. Hit "Read" and save the result. you should get a 393.216 bytes file.
                      3. fill with FF sections 5E000-5E3FF and 5F000-5F05F. Save new file, open into programmer software and write it back into EC.
                      4. you can also extract EC region from update searching in .fl1 file for header of EC region ( in my case 61870000 4E000000 DE070201 00002103) and selecting from there 393.216 bytes but you'll have warnings about serial, machine, name, etc and you have to write them with LMU. Attention, 8S label from motherboard has nothing to do with data you have to write in B0, you can take 1S (C0) and 8S (B0) from EC dump at 58000 or search for text SER#

                            Good day, I was trying to read the EC nuvoton with my svod 4 but it does not give me data, it only generates a file, I will attach a screenshot of what it reads

                            I did the steps as in the comment, however I was not successful.

                            any advice?Click image for larger version  Name:	Sin título.jpg Views:	0 Size:	389.3 KB ID:	3212985

                              when you hit " Read ID" did you get an ID? If not, check pins from programmer to correspond with pins from KBC connector with multimeter.

                                When it reads the ID it does have recognition, however I will do the verification and give the results as soon as I finish.
