Hi!

Please tell me your printer model. If we have the firmware for that model it will install without any problems.

Hi! It's the WF-2850. I ask because someone in my family may have updated the firmware to the latest. Hoping this wouldn't be a problem.

Just an FYI for anyone who comes across this. I was having trouble and this is what worked for me:

First, I couldn't get my printer into recover mode with the button code given. I don't think it works for the 2850. So, I just decided to try to run the program in normal mode as suggested above.

I ran the .exe that I downloaded from the website, but when I got to step 4 where you select your printer it said "downgraded (unable to update)" under status. I downloaded the firmware_99 file from this chain, and when I got to step 4 I had no problem! I ran the firmware update and when it was around 80% or so my printer restarted. Then the firmware updater popped up with the error that the firmware could not be updated. DON'T WORRY ABOUT THAT ERROR MESSAGE. Even though it says that, the firmware has in fact been updated. I just checked the version on my machine and it says "BL05K3". 

I have not purchased the key yet to try it out with the chipless cartriges but it looks like it worked fine. 

Thanks to the admin for all the detailed instructions. It's highly appreciated!

Hi @Admin, I have WF-2850. After running FIRMWARE, my printer shows "BL05K3". But the FIRMWARE Program says could not be updated. Is this the right firmware? Can I now activate online? I don't want to purchase because it says Non-Refundable. I want to make sure this is the correct Firmware.

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! 

After that try to activate again
