NOMI-VR VS Repetier-Firmware-4-Davinci

I have a Davinci 1.0a with Repetier 0.92.10 installed via the tutorial from Luc (https://github.com/luc-github/Repetier-Firmware-4-Davinci). Everything appears to function properly but the hot end and bed won't heat up nor is voltage being sent to them. I've pulled the plugs to the power supply and tested everything, it seems normal. I've checked fuse R271 and have continuity through it. I have a 4gb ADATA microSD so storage shouldn't be an issue. Do I need to change something in the configuration file for Repetier or should everything just work? What are some other points on the mainboard to check to help narrow down the issue?

I've had an XYZ DaVinci 1.0A for a couple of years now, flashed with custom Repetier firmware and connected to OctoPi / OctoPrint. It worked fine, until a couple of month ago the USB connection started getting flaky and I needed to power-cycle the printer to get USB back. Now USB disappeared completely. The printer apparently still runs its firmware (it shows its menu on the LCD when turned on), but there's to USB connection to the Pi. Plugging the printer into a different computer shows no USB device / only USB errors in Linux dmesg. I've tried resetting the firmware via J37 which should put it into firmware upload mode (acting as an Arduino board), but still nothing. I used an oscilloscope to check and there's activity on the D+/D- lines, so the cable is good, but the printer mainboard isn't responding. I suspect the Atmel ATSAM3X8EA-AU that provides the USB to be broken (at least the USB part). I could change the chip, but am unsure if / how I can flash the blank chip with the new firmware (an Arduino bootloader?). If you have ideas what else I should check or clarify the firmware situation I'd be grateful! If you need mainboard images, tell me. I have no schematics though...

Ok, let's start with the beginning... Before you flashed Repetier did it print and function normally? Next did you get the correct version of .92 , I think there are 2 or 3 different boards that require different versions. If you check this out https://www.thingiverse.com/groups/xyz-davinci-10/forums/general/topic:823 and this https://github.com/luc-github/Repetier-Firmware-4-Davinci. It should help, follow the procedure on thingiverse and re-flash with the binary from the github. let me know if it works after that. My 1.0 took a couple of tries and I had to send the M503 and M500 commands from pronterface to get it to start.
