Please try this new file for you.

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!
