I have a Bird ES4. Bought a new dashboard and replaced it but it's capped at 13mph. I tried updating the firmware using ESdownG but I get this error:
 sent retry.
I tried different phones, different firmware versions and then went to Ninebot Flasher on Win 10. Issue with that is that the scooter shows up on Bluetooth but won't connect no matter how many times I click connect.
The scooter works withe the Ninebot app but even then can't update the firmware. :/
Any help is appreciated
