    Invalid Serial Number issue

    Hello everyone, I received a new motherboard (bought on ebay). I connected it correctly but when I turn the machine on I receive an invalid serial number issue and I cannot move forward. I know the machine need activation but I do not know where the check is done, particularly for a spare part

    The seller needed to keep the SD card with the board. Without it, it is basically dead. There are 2 unique binary files [.bin] that manage the serialization that are required to operate the machine. one deals with the factory hash for the particular MAC address and the other for the registered reply code IIRC for activation.

    This is what should be there. You want the CFG and WPR files. One or both, with the original data, will authorize the printer.

    Start reading from here, I think this is a success story in the end. No promises. Long time since I fielded that discussion.
