Working with binaries from the newer models. Editing SN, Machine type and MAC and recalculating the checksums.

Update: IBMPass Editor Edition which contains the same features borrowed from IBMPass Pro (not published) is now available in our store.
You can use it to edit MEC binaries in native encoding, recalculate checksums, etc.

Note: IBMPass is a hexeditor with added functionality, does not read chips by itself!

New models based on Nuvoton have an interesting eeprom structure. Now there's a lot of room so Lenovo included tables for SVP and SMP including a log with everything. A null password is not just a null string of bytes so it won't disable the SVP request

We can edit everything: changing UUID, SN, Machine type etc and adjust the correct RFID and SVP checksum with IBMPass Pro or Editor Edition.
