It took me few days with so mant conflicting information to get this scooter to full potential so to save others time and money here is a quick write up on how to:
1-order a fresh dashboard on amazon this is what i ordered: https://www.amazon.com/dp/B07TSNVMM9/re ... UTF8&psc=1
, but they areall over ebay and amazon you don't need 50 bucks oem, it is so easy to install and many youtube videos on how tom you need a security bit to unscrew the handle bars. You can get a set here https://www.amazon.com/dp/B07Q21RPS2/re ... YFbTCRQVJ3
2- once the dash is installed, download the xiaoflasher app from google play store spelled exactly like this.
3-go to https://esx.cfw.sh/
. If you know what your doing, then you can go ahead and do it, if you dont, do what i did to avoid killing yourself or the scooter. Input the following settings:
B-basics: select DRV139 from drop down, leave the rest alone.
- drag the slider to 51000, to stay on the safe side.
-Max speed set it to max unless you want it slower
-Motor start speed: 2kmh
-Kers: if you dont wanr to die like i almost did select KERS/12 ("freewheel") and MAKE SURE NO KERS box is unchecked.
4-advanced:leave everything alone except last one, check the box "current based throttle algorithm." Withour this your scooter won't go past 16 mph.
lastly here hit finished time to cook and select xiaoflasher as your app, download the zip file to youe phone where you can find it or to youe computer and send to your phone somehow.
Go to xiaoflasher app,
1-hit the plug logo which will show your scooter if you installed the dash correctly and powered the scooter up. Once you are connected, and scooter beeps, click on select zip file then find the file you downloaded from instructions above.
2-hit flash selected zip file, DONT MESS with anything else yet, and stay next to your scooter obviously until its done.
3- once its done turn scooter off and back on, go back to the xiaoflasher app and connect to your scooter again.
4- if your scooter original serial that showed on top of the app or stamped on bottom of your scooter is N2GRK1841CXXXX or almost the same as this. You need it replace it with N2GTX1601CXXXX. Replace xxxx with last 4 digits of your current serial. Step 5 is how you replace it
5- go to "change region" and hit custom. Wait for the counter if u dont want to donate. Type in the new serial from above N2GTX1601Cxxxx. Replace xxxx with last 4 of your serial.
Hit submit and flash the new serial.
You are done your scooter will now ride smoothly , switch between modes and go rocket speed aka 23mph or more.
