                                  Find a 820-3115-B bios with clean ME firmware (post #32 seems ok) ,then edit it with your serial number (the one on the bottom case) and modify the fsys checksum.Watch piernovs video how to do it


                                  https://www.badcaps.net/forum/showpo...43&postcount=5
                                  4. DMI editing by brand

                                  4.3. Apple
                                  For 2017 and older machines, serial number is stored in Fsys store of BIOS and can be edited with hexadecimal editor. Fsys checksum needs to be fixed afterwards
                                  Search for "ssn", edit the serial number, save, open dump in UEFITool, go to the Fsys store and write down the suggested checksum in the panel on the right. Checksum is 4 bytes at the end of the Fsys store, between one zone of 0x00 either Gaid or another zone of 0xFF, it must be written in reverse order (so last 2 characters from UEFITool must be written first).
                                  See: https://www.youtube.com/watch?v=poA8HByYqTM
