[RADIOX]

У меня есть принтер Epson XP-2150, и я ищу способ сделать его бесчиповым, прошив оригинальную прошивку.

Может ли кто-нибудь сказать мне, как это сделать, как этот человек на этом сайте:

I have an Epson XP-2150 printer and I'm looking for a way to make it chipless by flashing the original firmware.

Can anyone tell me how to do this like this person on this site:

Chipless firmware for Epson printers

Here are some resources that may help you with this:

Epson XP-2150 Firmware: You can search for the firmware for your printer model on the Epson website or other trusted sources. Be sure to download the correct firmware version for your printer.
Flashing Software: You will need software to flash the firmware onto your printer. Some examples of flashing software include the Epson Firmware Updater Tool or the Epson Adjustment Program.
USB Cable: You will need a USB cable to connect your printer to your computer in order to flash the firmware.
Instructions: You can find instructions on how to flash the firmware on your Epson XP-2150 printer by searching online or consulting the documentation that came with your printer.
Here are some links to resources that may help you with this process:

Epson XP-2150 Firmware: https://epson(dot)com/Support/Printers/All-In-Ones/Epson-Expression-Home-XP-2100-Series/s/SF_130073#firmware
Epson Firmware Updater Tool: https://epson(dot)com/Support/Printers/All-In-Ones/Epson-Expression-Home-XP-2100-Series/s/SF_130073#firmwareupdater
Epson Adjustment Program: https://epson(dot)com/Support/Printers/All-In-Ones/Epson-Expression-Home-XP-2100-Series/s/SF_130073#adjustmentprogram
Instructions for flashing firmware: https://www(dot)youtube(dot)com/watch?v=5QkjCab3k7E
It is important to note that flashing firmware can be a complex and technical process, and should only be attempted if you are comfortable with the risks involved. If you are not confident in your ability to flash the firmware yourself, it may be best to consult with a professional.

Additionally, it is important to understand that flashing the firmware may not necessarily make the printer chipless. The chip in the printer is what allows it to use Epson ink cartridges, so removing or disabling the chip may cause the printer to no longer function properly or to not recognize ink cartridges.

Thank you for your interest in helping, sir. If I find the answer in the chatbot, I won't ask here.

wow, that printer runs Linux. I would try to burn the firmware file directly to the flash chip - maybe it is patched already.
but if the firmware is being patched by that .exe in the real time when you enter the "activation code" then you are out of luck.

but if the firmware is being patched by that .exe in the real time when you enter the "activation code" then you are out of luck.

you guessed right, that's what happened, I used Wireshark to capture the USB traffic and found the variables that the activator.exe collected to send to the online server to get the virtual bytes injected into the printer's EPRUM.

The code that is generated from these variables(in the online server)is the chipless activation code. Here is the code. :

bytes injected into the printer's EPRUM.

did you dump the EEPROM chip and check its contents?

most likely these are your computer and/or printer identifiers, to link the specific license file to one particular printer, so the license is not reused on multiple printers.
maybe a MAC address or something like this.

update: yes, this is your printer's MAC: "50:57:9C" = Seiko Epson Corporation

I found these articles :
https://www.synacktiv.com/en/publications/the-printer-goes-brrrrr

https://doar-e.github.io/blog/2022/06/11/pwn2own-2021-canon-imageclass-mf644cdw-writeup/

I need assistance with firmware extraction and analysis to prevent potential issues. also who helps me I'll pay him a few websites that monopolize this technique and i'm curious to figure that out

disassemble the printer and show photos of its motherboard.
the firmware most likely will be stored on a "25-series" SPI chip with 8 legs, I have an article about reading it with CH341a mentioned in your first link: https://xss.pro/threads/92416/
the EEPROM most likely will be stored on a very similar "24-series" SPI chip with 8 legs, and it could be read with the very same cheap programmer.
unfortunately reading the firmware/EEPROM might require unsoldering the chips.
