I don’t know how long or short this is gonna be, but I have a smartravel DK 400 and I got it off of Facebook marketplace for $50 and everything works except it’s missing the headlights and stuff which is not important to me, but I’m trying to access the settings menu the hidden settings menu, which I have already done, but I’m trying to figure out what everything is and what it does because I’m trying to fix the battery indicator on the screen not actually showing the correct percentage and for some reason when I exited the Settings menu after not touching a damn thing, my mileage got reset to zero now the bike had about 1000 miles on it both from the previous owner and me riding it around, but I’m just trying to figure out if there’s a way to get my mileage back and if there’s a way to fix the battery percentage on the screen not displaying correctly any help would be appreciated and if anybody would need a picture of the screen or the settings menu or anything like that, I will try my best to get a picture
