So this is quite the tale, and I have tried several things so far without luck.
I was stupid and bought a Ninebot Max on Craigslist and didn’t realize it was a former rideshare scooter (no markings). I hooked it up to the Segway app and updated the firmware and of course bricked it like a idiot.
On advice from a guy on reddit I ordered the ST-Link so I can unbrick it. I went through the process of taking out the controller, hooking up the wires and using the ST-LINK with STM32 to load the Dump126 file onto the controller, flashing it.
The controller did this once it was flashed:

Now when I hook everything back up to the scooter is does this:

Essentially it turns the display on once without error code, turns off and starts beeping and the brake light flashes. hiting the power button turns the light on/off and holding the power button turns off the scooter.
I figured maybe I need to flash the dash & battery as well. I started with the dash and took it out - here is where i f***ed up the SWDIO pad on the dash, it just "fell" off.
tried hooking up to the exposed part right below it but not getting a connection when i try to hold it to the exposed part and plug in the ST-Link to the USB port the display flashes once and beeps and turns back off
I'm pretty much at a loss here, I'm no expert or anything so I'm just trying to not throw the $400 scooter i bought in the trash, which is what I'll prolly have to do.
Any advice or last ditch efforts would be very much appreciated!
