I just bought the firmware to have a chip less ink cartridge system in my printer. I have downloaded all the necessary items that were Included but when trying to open the firmware, there is nothing that is coming up. I also clicked on instructions for my printer and it is showing instructions for a different printer. So I’m not sure how to get into the firmware mode.

 
Any help is appreciated!

Now I’ve downloaded a program and am able to install firmware. I click on it and Computer askes if ok to install. After clicking on yes, an error box appears with "could not find files needed to start."  
 

what am I doing wrong?

Hello!
Please try this new file for you:
 
https://inkchip.net/download/INKCHIP.net_Firmware_99_WF2850_v1.rar
 
1) Upload firmware which I sent
2) Switch on in normal mode(!!!) just turn on button . - dont put printer in Program Update mode. (No need to press few buttons while turn on the printer)
The uploading process will stuck at 70-80% - it is ok!
Open task manager and stop updater process.
Printer will blink for about 5-15 minutes - then will power OFF.
Now power on the printer - chipless firmware is installed in your printer!
