Yeah.  Basically, I'm not interested in doing all that stuff.  I'm a casual maker, and the XYZ is otherwise a pretty crappy printer in my experience.  Thanks for the pointers.

# Trying to flash Davinci XYZ 1.0, nothing but black bars

(Asked by: username_0 on 2016-07-04)

I get nothing but black bars and "Unknown USB Device" from Windows 10. This is after a failed flash that was otherwise going directly according to plan.

This Davinci has been nothing but frustration for me, and I'm really tired of fruitless Google-Fu.

Much of what I see pretty much says it's bricked; attempting to jump the jp1 jumper any further does me no good.

Is there anything I can do to actually move forward, or are we in soldering-iron territory now?

I had this occur on my [MakerBot Replicator Dual after I tried repairing a blown voltage regulator](https://3dprinting.stackexchange.com/questions/588/is-it-possible-to-use-an-aftermarket-controller-on-a-makerbot). If you refer to the previous link to my SE question, pay attention to the comments of Ryan's answer where it is explained that (in my case at least) the main processor was damaged and therefore couldn't properly load the firmware.

I'm not certain that you're encountering the same EXACT issue, but you have all of the same side effects that I did. Basically, if you're not pro with electronics, your board is bricked. Otherwise, you ***might*** be able to salvage the board by replacing the processor, but there's no guarantee that something else isn't wrong or that the new processor was installed correctly.
