    Is there any way to edit the firmware of these printers? Or someone who knows the method to obtain the firmware?
    What is your board model ?

        I believe it's version 1.1.3.4. What tools do I need to decompile this firmware?

          First you need to extract/decompress the firmware using offzip.
          offzip.exe -a "pantum toner empty.bin"
          You can then disassemble the generated "00020120.bin" ELF file with Ghidra.

            Thanks for the help, I was able to extract the bin file and working on getting ghidra up and running.

            I found NoChip_CA2J000228_P2500w_1.2.9.7.fwr and downloaded the file.

            Do you know where the printer ID is stored in the fwr file. I was hoping to just use hexedit and overwrite my printer id in the this modified file.

            BYW I can't send you a private message

                BASE64 decode that string and you get "CA2J000228P2500w".

                      Overwriting the serial number in base64 will not help, the rest of the contents are encoded by the firmware program.

                          Try flashing this in spi flash.

                            Just tried it, it keeps flashing green led2.

                            Also it has a wifi password setup

                            also tried test print and it gives error message.

                              Need help with modding printer id in my backup bin file.
                              I tired to change to CA2J000228, but after flashing it reads AA2A000000.

                              I attached original and modify file.

                                There is a checksum somewhere I think.

                                  Do you think the printer id is also stored on another chip also? or only in firmware

                                    Probably not. You can change the serial number via USB by using the AclSetSerialNumber command. I also checked the code that writes the serial number to the flash chip, and it does calculate a checksum.

                                      Try this checksum. It should be correct.

                                          Just went back to backup firmware bin, now printer is printing!! it's say 35% used.
                                          Tried covering chip and won't print but now have 35% used and able to print.

                                          I made image backup and tried again the fwr chipless firmware and the printer bricked.

                                          Just to confirm it was not a hardware issue, I upgraded firmware through pantum tool and it updated my firmware no issue.
