Upgrade your internal and external BMS to latest version using NineRift or similar.

Hi,
Thanks for your detailed guide How to flash...worked for me.
Now, If I connect second battery, get error 42. So scooter is still unusable for me, dont have enought power to enjoy the ride.
Hope that sobebody knows how to solve this error and will share the solution here.
Thanks!

did you ever figured it out ?
Try to push external battery against the connector when error 42 turn on. If it stop it's the connection between external battery and controller. Take something smal and scrape inside. Check if some plastic is in the way and reconnect the external battery.

When I turned on my es 2-300 Friday it is flashing a code error 45 and the lights are flashing when the motor is turned on and is slow it won't even pull with weight on it. I have looked for loose connections throughout the entire machine to no avail. And my frustration level is at Max.

I have a ES4 that was x-Lime. Bought it a year ago and works great. I haven't used the app for MONTHS (but was using the scooter) and fired it up the other day to turn on the lights for X-Mas effect. Was prompted to update the app, then the scooter's firmware....big mistake.

Scooter will power on - all looks well but when you start rolling and hit the throttle it speeds up for a second and then starts beeping, red wrench, and flashing code 45. Can't find anything definitive on code 45. This all happened with the firmware update....so I'm assuming that is the issue.

Anyone know if hacking/flashing will fix this?

EDIT - I ended up hacking it with NineBot_IAP on Windows 10. This brought it back to life. I then changed the 4th digit of the serial # to T and got the disco lights back also. Guessing code 54 is something to do w/ a firmware "brick" of unauthorized scooters.
