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....Last edited by DJ_MIX; 04-29-2023, 03:19 PM.Leave a comment:

Re: Pantum P2502W Toner Reset Chip help
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...Leave a comment:

Re: Pantum P2502W Toner Reset Chip help

Re: Pantum P2502W Toner Reset Chip help
Guys check out this page, they have modified the firmware to require no chip.
I hope we can reverse engineer what they did or just pay the small free to the firmware:

WN111v2 WIFI usb stick add external antennas
Would like to add external sma connectors to usb wifi. Any experts out there?
Would this work cut the two traces as pictures and attach coaxial ground to points shown.
I can take better pics if needed. I will most likely use pcb mounted sma connectors on the sides....Last edited by DJ_MIX; 04-04-2021, 04:09 PM. -
Re: Pantum P2502W Toner Reset Chip help
Guys, I finally read the contents of the bios chip with the toner completely full not usable.
I also read the chip when I only used a few pages but I don't know how reliable the bios chip read was since my old programmer did not support that chip.
The latest dump read 100% accurate. Maybe someone that know how to read the contents can help. I might just write the pantum toner near full.bin back to see what happens...Last edited by DJ_MIX; 12-22-2018, 09:12 AM.Leave a comment:
