do you have the flash files for all 3 things ??? send me message if you have or where i can get it
Don't lose time it will not work unless you found a way to loop the motherboard into reset mode like they did with ninebot g30 and snsc 2.0 boards. And to flash bms you also need to dismount the whole battery pack. Iap bms flashing change only the version number
what can i els dooo with it ?? maybe motherboard from max G30 ?
You Will need to flash bms by st link I think then create a special cable to connect the battery to the g30 mb

1. Flash bms on P10 with iAp CP2102 UART to USB adapter
2. Flash esc 126 full dump by 3 wires to STLink and plug-in power in charge port.
3. Flash ble 555 full dump by 3 wires to STLink and plug-in power to the Dashboard by scooter.

Mine run well since July. You have first to flash the BMs by ioT port (iat) then do an stlink to the ESC with retail firmware G30 and do stlink or change dashboard. If you flash the esc before the battery, you will need to stlink the battery too

Okay, I'm a little stuck here. Where should I put the uart pins on the battery? And where should I connect my st link on the esc? Any help would be greatly appreciated!
