    Try this checksum. It should be correct.
    May I ask, how did you determine the correct checksum?

      I used the firmware checksum calculation function.

          What tool? I looked at the disassembled Pantum firmware in Ghidra to see how it calculated that checksum.

              AA = address (big endian)
              SS = size (big endian)

              I extracted the ACL command/function information from a debug build of the firmware.
              tell me what the command should be to change the serial number 00 AC FF 04 00 00 00 00 00 00 00 00 00 00 00

              hello, please help me deal with the Pantum printer, I'm interested in the ACL command AclSetSerialNumber 0xFF04, what should the command look like? look at an example of a file in hex and tell me where the error is 1B 25 2D 31 32 33 34 35 58 40 50 4A 4C 20 45 4E 54 45 52 20 4C 41 4E 47 55 41 47 45 3D 41 43 4C 0D 0A 00 AC FF 04 43 4C 31 39 39 32 30 37 31 38 30 30 1B 25 2D 31 32 33 34 35 58
