VERY IMPORTANT
Ninebot disabled the SN changing functionality on DRV271. To change the SN on these versions please downgrade the firmware to a lower version.
Using ScooterHacking Utility, to Load Original > DRV > DRV271 and install it. This is a modified version of the update which allows firmware downgrades. Then go to Load Original > DRV and choose any version lower than 271. I suggest 255. This will allow you to change the serial number once again.
