NOTE: I just now signed up for this forum because I have this issue, and you might notice this issue is also found on 3dhubs.com. I want to get as much help as possible as quickly as possible. I hope I can get my printer fixed.

Anyways...

So I have a Qidi Tech 3D Printer and I wanted to put Sailfish on it.
I had seen this thread ( https://www.3dhubs.com/talk/thread/avatar-iv-qidi-tech ) and I followed Adam's advice on installing the firmware (following this video: https://www.youtube.com/watch?v=Z_Y9tCpsn3E ).
I made a mistake, though. When I went to install the 7.6 firmware in ReplicatorG 0040, I accidentally installed Sailfish 7.6 (I had already updated the preferences in the ReplicatorG 40r33 Sailfish).
At first, the printer did like in the video, and just froze up. But when I went to install Sailfish proper, it wouldn't work. I tried Sailfish 7.1, 7.6, and 7.7.
I then at one point tried going back and installing the normal 7.6 firmware in ReplicatorG 0040, that didn't work.
Eventually I had restarted the printer by turning it off and on, and now the LCD screen is completely blank.
Makerbot Desktop does see the printer, and I can access all the EEProm's even. When I go try to update the firmware in Desktop it shows the printer having firmware 7.6. I tried firmwares 7.2, 7.3, and 7.5. None of them worked.
I did the same in both versions of ReplicatorG. Again, no result.
ReplicatorG will say the printer's firmware is Unknown v0.0, Unknown v7.6, or nullvar.
I have tried pressing the reset button before, after, and at the same time I press the upload firmware button.
I can't tell if I just need to keep at trying to upload a specific firmware, or if the printer is bricked and I need one of those AVR programmer things.
