Hi! I just bought a Firmware Key to make a WorkForce 2750 Chipless. The problem is that while i was doing it, the printer says "NOT WRITTABLE" and just went off. After that, the Printer just got locked at RECOVERY MODE. i was able to reinstal the firmware, but it keep the same firmware vesion and still asks for cartridges.
Then i tried the process once more, but now it says that the key was already used
Other times i had no issues, just this one time. Hope you can Help Me
My Order Number is # 260379
