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.

Kado09, take a look at post #10 on page 1.
I posted pictures of my board long time ago.

Thank you all for your help, I hope this also helps others.

I can help, I need an exact model of the board that is written on textolite.

Thanks once again, I think I got it.. Maybe during weekend will attempt.

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

Can someone modify my extracted firmware. I used a spi programmer to read the chip.
Btw this a early firmware

BASE64 decode that string and you get "CA2J000228P2500w".

File attached, Chipless firmware just need to figure how to modify for your printer ID.

Re: Pantum P2502W Toner Reset Chip help

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

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

Re: Pantum P2502W Toner Reset Chip help

Hello, I have been trying somehow to make the pantum p2500w printer work without the chip that the toner comes from the factory.

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 can edit the firmware and know how to make it work without toner chip, but it is too much work, sorry.

Re: Pantum P2502W Toner Reset Chip help

I just ordered a P2500W. The toner chip communication is encrypted, according to the disassembled printer firmware, but I have all the necessary information (I think) to read/write the toner chip data using an arduino. If anyone is interested in a modified firmware that e.g. sees empty toner cartridges as full or wants to reprogram toner chips using an arduino, let me know.

i am interested please

Re: Pantum P2502W Toner Reset Chip help

Is it possible to change the serial number of the printer program?

[Fixik2020]

Re: Pantum P2502W Toner Reset Chip help

can i get the source code of the program? private

Re: Pantum P2502W Toner Reset Chip help

Yes. @timschuerewegen do you think it's OK I publish it?

I don't know

Re: Pantum P2502W Toner Reset Chip help

ok, do you have a program?
