Suggestion on updates for Max G2 E

Hi there,

I purchased an European Ninebot Max G2 E serial number: 01GY last December. I activated it in app and then I immediately used XiaoDash for Android (if I recall correct the name of the app) to set it to Global and achieve features locked in Europe such max speed at 35km/h and Cruise Control. I then activated the scooter in app. In app the serial number has changed to 01GX. I'm since then on firmware 1.4.4 for Main Control, 1.7.5. 2 for Battery and 1.6.10 for Bluetooth.

Since the beginning the only problem I have with my scooter is that when I reach 33-35 km/h in flat or slightly downhill roads intermittently happens that the scooter briefly "cut" power (it happen so hard and bad that it seems like the scooter itself brakes) and then it starts again pushing.

I've read that update 1.7.6 maybe solve this issue (I don't know if someone her has experencied an issue like mine). Segway app right now suggest to update to 1.7.6 for the main unit, 1.11.0 for Bluetooth and 1.7.5. 5 for battery.

So here are my question: has someone with a European model in my situation updated firmware after the hack without losing max speed and cruise control? Because I'm just terrified to update it and lose the max speed (I know you will understand how 10kph feels like a huge amount of speed when you are forced to go to 25km/h) but at the same time I'm scared that this continuous "power stall" at high speeds could ruin the engine.

Thanks for your time!
