Some ppl say that the motherboard use a unique key to unlock flash capabilities. And they want you to pay an abusive amount of money to fully convert your snsc 2.3

lol, you can flash the esc with an stlink, same pads as on the max g30, just in a different place, also needs 5v but easy to figure out where, no such thing as an unique key to flash it, can flash it with drv 1.2.6, just need to know what youre doing

flash the bms over uart tho might be too late now as the esc is flashed but worth a try, err 27 goes away when you change serial

Update:
I flashed to esc 1.2.6 and scooter can now drive when i bypass error 27.

Was hoping i could flash bms over Bluetooth, since i havn’t figured out how to open the battery hatch lock.

So you just used an st link to flash the scooter? Or uart flashing? And does the original dashboard work for Bluetooth app?

did the esc with stlink, and the battery with uart flashing,think the org dash works with bluetooth tho unsure as i just changed them out with clones, kinda hate the 4 dott displays, and they are unstable as you have to use ble 555, so nothing for me, better to just change the display

And here you can connect the 5v!
In this case you dont have to solder more than 3 connections

Thanks for all informations! I have a last question): can I use an arduino as an uart to usb adapter for ninebot iap? Because I don't want to wait 2 weeks for an adapter. If everything work correctly I will update this topic as a tutorial.
