Just want to say thank you for this tool. I unlocked my E25E to 27kph (28kph for the gf). Using my old ES4 external battery on it at the moment and while it gives the extra range, it doesn't unlock the extra torque or max speed. So fingers crossed custom firmware is also out soon so this ext battery acts much the same as the official E45E battery.

Donated a couple $ each for this and will do so again when CFW is out. Thanks again.
What's your fimware version ? do you have the Ninebot E25E updated to 2.5 firmware ?
I downgraded to 2.3.9 before doing this serial number flash. You can do it as well using Xiaoflasher on an Android phone if you're having issues with the latest firmware as many others are having.

This is a doozy of an issue.

I bought an E22 with external battery yesterday from a classified ad. Couldn't power it on so I wen't home and charged it up. After about 5 secs, I got an Error 10. Talked to an acquaintence who has one and his did the same thing!
Of course the ES4 error 10 relates to the serial number, so I can only venture to guess it's pretty close on this scooter.

I can't connect to Segway app (both old and new), PC, xiaoflasher, and the IAP won't work either. I need heellllppp!
Whoever told you that error 10 is in any way related to the serial number clearly doesn't know anything. Error 10 indicates problems with communication between the dashboard and the controller, which might be caused by a couple things;
1. Ripped or damaged cables
2. A poor attempt at flashing custom firmware made for the wrong model, or in the wrong format.
While the second one can't be fixed atm, the first one can be narrowed down to a certain point of failure and fixed with relative ease. You'd have to inspect the cable going from the screen to the controller looking for damage.

My method simply cannot cause any errors or bricks, it's literally not possible. If you were wondering which error codes correspond to the serial number, it's error 35 and 27, you can check out a full list of ninebot error codes here: https://scooterhack.in/nberrorcodes
You sir, are a gentleman and a scholar. I did fix my error 10 and made my E22 go 20mph! Here's what I did:
The E22 has a great frame and tires that handle pretty much like the Max. So why would Segway only let it go 12-15mph!

Step 1. Take out the E22 Dash and set it aside for now.
Step 2. Remove the stem and slide out the battery and ESC and set them aside for now.
Step 3. remove ES4 dash from the shipping envelope it came in, install in E22 handlebar.
Step 4. remove ES4 ESC from shipping envelope and connect to battery, reinsert into E22 stem and connect dash and handlebar.
Step 5. reassemble your new ES-22.4 and flash your favorite Scooterhacking cfg file! :)

Any idea on why my ninebot E22E goes only 24km/h max on smooth pavement at full charge? On free wheeling it reaches up to 29km/h but never goes more than 24km/h on smooth ground and I'm only 65kgs.

I've found my E22 almost has a "mood of the day". At Red S - Sometimes it will blow off at 27kmh on smooth pavement, other days 24.
Torque can also be worse at times, not only top speed.

I have noted it is slightly connected to the headlight - and also take it could be low accuracy in the sensors of the bike.

Will see if the newly received 2.5.5 master control update has any effect - anyone else received it?
Very little talk about it on any forums.
Located in Sweden (in case it's region dependent).

Hi! I own a Nineboot E45E scooter and I'd like to increase the maximum speed at 30 Km/h, because my scooter is limited to 25 Km/h in sport mode. Will this method work? Which code should I use to perform this operation? Thanks in advance!

PS: my scooter has its last FW.
