ES2L - Changing Serial and flashing? Im so lost...

Postby ChrisFox89 Tue Jun 30, 2020 1:00 pm

Hey guys,

I rarely ever go to specific forums based on topics like this and often end up on Reddit to find answers but Im not getting any there right now.

So basically I ordered what I thought was an ES2 but is actaully an ES2L. Now i've come to understand the only difference between these models is a restriction on the speed to 12.5mph.

I just bought the battery to upgrade to essentailly ES4, but now i realise that while it will give me more range and acceleration, it wont increase my speed.

I've tried EsDownG because I didnt realise I had to change my serial number, so naturally nothing happened.

I tried the microsoft store based 'Ninebot Flasher' to try and change the serial code but after a couple of attempts, the flasher pretty much doesnt work any more. Just a greyed out boxes when I open it up with the scooter connected.

So where do I start? I just want to increase speed to about 15-18mph nothing outrageous.

I know I have to start by changing my serial, but I suspect that even before that I may need to downgrade my current firmware? I'm on 1.5.1 as of earlier today.

thanks and I look forward to any help I recieve.

I just wanted to add that earlier i tried to flash my scooter on Ninebot Flasher and since then, the app cannot find my scooter on bluetooth. So it would seem that the firmware has stopped it from being seen by Ninebot Flasher somehow. Damn these scooters are so complicated and I build PC's often.

Hello. help me please. I have flashed my ninebot es2 scooter with firmware from the internet and now I have changed error 21 and the wrong serial number. Ninebot Flasher can't see my scooter, but XiaoFlasher can see it. Help me please. I have a St-Link programmer, it can be used to return my serial number

Return to “Ninebot ES”
