Help Troubleshooting Ninebot One E+ or repair shop recommendations?

I was coming home from the gym in 95° weather at about 12 mph with 70% battery on the sidewalk. I saw a bump coming up and decelerated pretty hard. I'd estimate I hit it at about 8 mph while still leaning back. This is my normal daily commute and my wheel handles this bump fine every day while it's vertical. The wheel bucked me off. Luckily I was able to keep my feet under me and run/stagger to a stop... just to watch my wheel bouncing ass over teakettle for another 50 feet beyond me before it finally fell onto its side on the grass. As I approached, its lights were red and it was beeping, so I stood it up, which normally stops the beeps, but it kept beeping. So I turned it off and on again and the motor wouldn't engage. It does beep once to signal that it's on, though.

 So I carried my poor baby half a mile home and let it rest in my basement for about 30 minutes. When I turned it back on and noticed green flashing light- the lowest bulb on the rear of the circle on both sides. I bet that's an error code? The internal temp according to the app was at 90 degrees Farenheit. I tried disconnecting and reconnecting the battery, and tried holding down the power button while doing the same. The motor won't engage at all and the Segway-Ninebot app says "Total System Current: 0.0A." Could it be a blown fuse that I could replace myself?

I tried submitting a ticket to ninebotrepair.com but haven't heard back after 3 business days. They don't seem to have a phone number. Are there any repair shops in the DC/Baltimore area or anywhere I can ship it to?

I do want to keep this wheel (or replace it with a similar sub $500 one) so I can have a trash wheel to teach friends on and let them ride with me after I save up enough for the v11.

Welcome @ASHNoNa!

Is there an unusual resistance if you try to turn the wheel?

This could be a sign of blown mosfets and a new motherboard could/should help.

Batteries are fine? The both individually deliver the right voltage and charge up fully?

All wires and connectors look fine?

Afair e+ has no fuses?

Thanks! No abnormal resistance when I spin the wheel. All wires and connectors seem fine on visual inspection. Batteries seem fine. I haven't tried to charge it yet. The app says "Drive voltage 57.2V" when I turn it on. If its the motherboard, would it still beep and light up? Didn't know it doesn't have fuses,  thanks for letting me know.

As the wheel turns freely it seems to be not the mosfets.

I would not swear on it, but that's what i assume to remember...

And fuses, as they are used with ks would fully cut the power supply - so no supply anymore for the motherboard.
