Hello!

Please try this new file :

 

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!

 

After that try to activate again.

To extract a file you need to use any archiver. For example, WinRAR or other unzipping program.
