Yes that is what happens when you put retail firmware on a rental scooter.

I wrote many forums but no one help or suggest or give any clue of my dashboard. Since I bought 2 scooter without battery pack luckily I found 1 pack in auction :) .

Last week I did too many trial and error, well finally I figure it out how to flash to stock firmware all 3 items, (dashboard "BLE", battery controller "BMS" and driver "ESC")

Now battery leds are shows battery level, also its possible to charge battery from sockets,
ESC is working without IOT (unplugged GPS/GSM module "wasn't included sim card")

My dash was bit different. I believe it's a new version and c2 capacitor is located back of the board. I could flash with 555 firmware.

Dashboard is operatable now also possible to connect via bluetooth. Dashboard shows battery capacity while idle. Bluetooth name "Change.Me.Pls" is coming with 555 firmware. I changed with hex editor.

There are some minor problems on dashboard side. The firmware I found on internet is for 350 max but not for "max plus" therefore

1. Dash is always on (on/off button not functioning)
2. I couldn't turn on headlight (single press to on/off button)
3. double click (on/off button) is not changing modes (stays always "S " mode)
4. max plus has 2 brake lever (left one should be disconnected from dash sockets) otherwise giving error 15
5. tail light is not flashing when brake applied.

I couldn't find correct firmware for dashboard yet

All bluetooth settings are working from mobile, info screen, speed etc. Scooter has 30 km top speed at the moment

Good Luck
