WF4730 cannot update firmware or activation

Recommended Posts

Hi, I downloaded WF4730 firmware and activation software. When I tried to update my printer in normal start it would not detect my printer, but if i put it in program update mode it will, I tried to proceed with the update in program update mode which will go to 100% and show Finished on my printer screen but when I move to activation step it will not show again. The firmware doesn't seem to be able to flash my printer as the firmware version does not show CM99Z9 after update. Please help.

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!
