I just tried an older 8G USB 2.0 pen drive, and that was the same behavior:
Are there any additional steps I can take myself? I am not going to spend any money on Xerox support at this point since I would rather spend that money on something else. I am very technically savvy and am willing to reformat drives, write images or drive headers or whatever is needed.
Today I attempted to update the firmware on my WorkCentre 6515 using my Mac. The firmware upgrade utility found the printer via bonjour, and looked like it successfully update the frimware. I saw the firmware loading, and it got to the end of the progress bar and the printer rebooted. During that time, the printer said something like "an admin is making changes".
After the printer rebooted, it would not boot up fully, it is stuck on the splash screen, the blue screen with "xerox".
Since then I have also connected a Win10 laptop to the printer but it is not recognized via USB. I have taken a USB drive, formatted FAT32, put the firmware file in a "DWLD" folder, and booted into the special boot menu, and then into "Download mode". The USB drive flashes twice as it is being accessed but then nothing happens.
Is there anything else I can do by myself? I bought this printer 7 months ago, and I believe I get no more free support from Xerox.
What really bums me out is that I followed a supported procedure using the Xerox software and it bricked the printer.
