Firmware upload seems to work as it does in the instruction video.  However when I try to use the activation program nothing works.

Generate = Wrong ID Code

activate online = Wrong ID Code

I put in the activation code e-mailed to me and when I click Activate I get "Activation code can not be recognized.

 

Any help would be much appreciated.

Hi!

Please try this new file for you.

 
https://inkchip.net/download/INKCHIP.net_Firmware_99_WF3720_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!
