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

Re: Pantum P2502W Toner Reset Chip help

00 AC 00 09 AA AA AA AA SS SS SS SS 00 00 00 00

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

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

what will help??

Ok thanks, is that tool only good for pantum images? or work with other firmware images?

I used the firmware checksum calculation function.

Re: Pantum P2502W Toner Reset Chip help

May I ask, how did you determine the correct checksum?

Try this checksum. It should be correct.

Re: Pantum P2502W Toner Reset Chip help

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.

Thanks that let me flash fwr, now the problem is that takes flash and then bricks
printer, both leds turn off and printer has no power.

try two different fwr's one with 3.2.2.8 firmware and 1.2.9.7 fwr both not work.

Re: Pantum P2502W Toner Reset Chip help

I tired to change to CA2J000228, but after flashing it reads AA2A000000.

Re: Pantum P2502W Toner Reset Chip help

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.

Re: Pantum P2502W Toner Reset Chip help

There is a checksum somewhere I think.
