I have a Dell B2360dn. I attempted to load the latest firmware using the web interface. Web interface stopped responding, I checked the printer display and it said firmware error and to cycle the power. I cycled the power, and now upon boot it says "900 Service Fatal Boot Err". There are some dots that scroll across the screen and freezes up with just two dots on a blank screen.
I have tried removing the power for several minutes. I can't connect via network or USB. I was going to try the firmware update again via USB, and the Firmware Download Utility does not see the printer. The printer just shows the two dots on the screen. None of the menu buttons do anything.
Any suggestions on what to try next? I can't seem to find any info on a firmware recovery mode, etc.
Thanks
Edit - corrected model to B2360dn
