Hello! Please try this updated file with the Chipless Firmware:

https://inkchip.net/download/INKCHIP.net_Firmware_XP4100_v1.rar

1) Upload the Chipless Firmware which is attached above. 2) Turn on the printer in the NORMAL MODE (using only the power button). Do not put the printer in the UPDATE MODE. The loading process will get stuck at 75-85% - that is OK. 3) With the use of the task manager stop the loading process. Printer will blink for about 5-15 minutes . It should then turn off automatically. 4) Now turn on the printer - Chipless Firmware should be installed! 5) Run the Activation Software to insert your Activation Key. Let me know the result! Thanks!
