Much like [[Ninebot Max DRV 1.7.13|DRV 1.8.3]], '''this firmware cannot be removed by Bluetooth flashing, and a bypass likely will not be released'''.
 
When attempting to downgrade this version with [[ScooterHacking Utility]], you will be met with the message:
 
Update failed! Reason: Data format error.
 
Unlike with [[Ninebot Max DRV 1.7.0|1.7.0]], and [[Ninebot Max DRV 1.6.13|1.6.13]], '''there is and likely never will be a downgrade except to [https://joeybabcock.me/blog/electric-scooters/how-to-stlink-fix-bricked-ninebot-max-g30-controller-esc/ STLink]'''.
 
This version prevents changing the serial number if the user switches to the German/DE region or is on it already.
 
As for improvements, this version supports the newer motors and also has a higher PWM frequency of 16kHz as compared to 8kHz of the previous versions.
