As described in our Ninebot ES/SNSC Speed Controller Flashing Tutorial, many recent rental scooters are now using properietry firmware on their Electronic Speed Controllers (ESC) as an additional anti-hacking measure causing the following issues:


1) After dashboard is replaced, lights blink and/or scooter applies brakes

2) Dashboard displays error 10

3) Dashboard displays error 35


This service flashes (programs) Origional Firmware (OFW) onto your ESC "unlocking" it and restoring normal functionality. This flashing service also changes your scooter's serial number unlocking all 3 power modes. If needed, please select any number of the additional services we offer to get your speed controller back to original functionality. The additional price for each service is listed in (). If you just need us to flash your speed controller, don't select any additional service options.


Cable Replacement (+$10) - Temporarily out of stock due to supplier delays

Some scooters (ie: Lyft, Spin, VOI) use a custom 5 pin Julet connector to plug into the tracker box instead of the standard 4 pin used by all dashboards. This service installs a 4 pin connector so you can connect your dashboard to your speed controller.


Fuse Bridge (+$2)

If you turn on your headlight and your dashboard dims, speed decreases, or your throttle stops working all together, this is the fix for you! These issues are caused by a self resetting fuse which regulates power to your dashboard and tends to wear out pretty quickly. Even if you don't have these issues, it's a good preventative measure to take so they don't develop in the future.


Gel Removal (+$10)

Certain speed controllers are potted in a thick silicone gel to make them more water proof. This is an additional fee for such speed controllers as removing the silicone gel is difficult and time consuming. You must select this option if your speed controller has silicone gel. 


Waterproofing (+$5)

We come across a lot of broken speed controllers where water has corroded the surface mounted components located at the bottom of the PCB. While many ex-rental speed controllers are already semi-waterproof with a thin layer of conformal coating (basically nail polish for circut boards), it's often applied very conservatively and still allows water damage. With this additional service, we'll apply a nice, thick layer of conformal coating to your speed controller to improve its water resistance.
