CM2350F Xcal convertor question

[DaneF]

Read a clean stock file via Calterm from a 2018 6.7 Ram. Converted to .ctz with Xcal convertor. Now getting Checksum invalid. Apparently OS isn't supported by EFI live so may have to find alternative base file. Is this common or did I mess something up? Just in case i need to revert back don't want to brick an ECM. Thanks. 24174

I assume you made changes in Calterm then exported to bin with Xcal. Force checksum correction then you'll be good to go. If it wasn't supported by EFILive you wouldn't even get a checksum verification when opening the file.

No changes were made yet was just trying to save my stock file so I can revert back if need be. Forced correction now says okay to flash. Thanks
