Ninebot ES/SNSC Custom Firmware (CFW) ST-Link Flash Tutorial

[@kalkurap]

Followed the directions here and another video on this channels which shows how to flash the speed controller. I was able to successfully re-flash a spin scooter without much trouble. Thanks Banana Science!

[@joshtaylor9585]

@kalkurap I'm getting ready to try and do that. What version of spin scooter was it Max or Max Plus? Could you give me any advice/ tips/ help lol.. btw I'm kinda a novice I know a lot and have played around modding several scooters but completely new to flashing although I've read a super ton on it maybe too much 🤯 appreciate any advice you could give

[@georgepentafragas2200]

Hello to everyone. I have an ES4. I have never hacked anything. With the last update from Segway, which i think it was released about 3 weeks ago, my scooter now goes up to 32km easily. Also it used to suddenly brake when i was going downhill in order to not pass 32km (which was a bit dangerous) but that braking is also gone. Yesterday for example I went 40km downhill.

[@Zamani3033]

Is this with full battery and without cruise control?

[@georgepentafragas2200]

@@Zamani3033 No cruise control. Battery doesn't matter if it is fully charged. I get 32km even if the battery is at 50%.

[@KagerouXD]

Thank you very much for the clear tutorial... worked perfectly for me after flashing the bluetooth dashboard. Though I could not flash the control board but that is not the issue causing my wheel to rattle when it turns, I found out that one of the hall sensor wire connecting to the motor is broken, so join them back and its working perfectly now.

[@mashedpotatoes5323]

I have a custom dual motor ninebot es4 with two 48volt 1000watt ebike ESC's and a 13s10p 25ah battery I made that I'm going to upgrade to 14s soon, everything is mounted a bit half-assed right now as I don't have any tools to make metal mounts but it goes 25mph right now and has a lot of power and will go even faster with 14s so it's just the ninebots ESC that limits the speed as more voltage makes the motor spin faster.

[@BananaScience]

That sounds awesome! You don't have any issues with motor heat?

[@mashedpotatoes5323]

@@BananaScience not running with two motors it doesn't, adding a second motor makes it so much faster and since it has more torque it's able to stay at 25mph on flat ground without getting hot, if I'm going full throttle uphill in the grass it gets pretty hot though but only after a few minutes. When I first built it I was running with one motor and after driving it around my neighborhood full throttle the motor hurt to touch. I also haven't had any problems with motor wires melting or the bullet connectors which I'm still using. I plan on making a video on it but I'm kinda embarrassed how it looks right now and it would be filmed on my potato phone.

[@BananaScience]

@@mashedpotatoes5323 That's pretty sweet. Where do you mount the ESCs?

[@mashedpotatoes5323]

@@BananaScience I have everything mounted on the floor at the front of the scooter with hose clamps and rope (it looks terrible and like a bomb), the back is extended to fit the rear motor so I still have plenty of room. When I'm able to make a metal bracket/ housing in a few months the ESC's and wiring will all be sealed up in a metal box bolted to the floor of the scooter. The battery will be covered in some type of plastic wrap and will be able to attach and lay flat on top of the case for the ESC's and will be easily removable, I'll add a small fan and air holes to the ESC's housing so it doesn't burn up but I want it water resistant as possible too, and I'll also add some foam padding to protect the battery from bumps.

[@mashedpotatoes5323]

I'll also be adding a bike break to the rear motor, the metal edge of the hub will be used to stop it and I'll be replacing the foot break fender (I had to take off since its extended) for additional breaking if I need it, although the foot break will wear out my tire.

[@BananaScience]

Is it an ex rental scooter? The two electrical components people confuse a lot are the dashboard and the control board (AKA ESC). If you have an ex rental scooter you will likely have to flash the control board as well as the dash to get it to work.

Use a earlier version of firmware. I think the latest version Ninebot Flasher accepts is 1.3.9. If it's any other version, it will throw an error.

[@mrdwil777]

BananaScience Have you heard of when the ES4 gets to 22 mph it quickly applies breaking and goes to 19mph and then cycles doing this?

@@mrdwil777 Yes that is normal. CFW only guarantees stable speeds up to 20mph at the moment and anything above that will have that strange acceleration and declaration issue.

I flashed the stock firmware onto my dash I got off amazon because it wasn’t working with the rental scooter I got but now it just flashes the red wrench signal. Help?

[@BananaScience]

Eli Johnson what is the error code? If it’s error 10 you will need to flash OFW onto your ESC using an ST Link. Check the forums linked in the description for more details.

[@elijohnson1832]

BananaScience well the dashboard I have for some reason isn’t able to connect to the app. The app recognizes there is a scooter but when it try’s to connect it said connecting fail please try again. I was hoping flashing the dashboard would make it work but it still doesn’t. I am going to try to flash the control board later today with the st link. Should I just do the same thing I did to the control board as I did to the dashboard?

[@BananaScience]

@@elijohnson1832 Sometimes the BLE is a little flaky so you need to try to connect a couple of times before it works. The process for flashing the ESC is completely different so I would check out the forums for details on that. We hope to release a video on how to flash the ESC within the next month or so.

[@elijohnson1832]

BananaScience okay thanks so much for your help. That video would be greatly appreciated! I did find a few steps for flashing the esc so I hope I’m able to follow all them because I’m not to familiar with STUtility(which is what the steps say to use).

[@Kchecksitout]

Hi there, I have recently acquired a couple of impounded scooters from a wrecker and they are lyft branded. The main cable from the esc has 5 pin connection going up to the dash as the replacement ones only have 4 pins. Would this make a difference?

[@BananaScience]

Yes. You need to find out which of the five pins has battery voltage (use a multi meter to find 42v) and then just purchase a replacement 4 pin connector and ignore that high voltage pin when you wire in the replacement cable to your ESC.

[@Kchecksitout]

@@BananaScience Ok, thank you so much for the information! Is the 42v there to power the dash that came with it? if i do ignore that would it still have the sufficient connections to power the replacement dash?

Do you have any advice? Thank you for this info

To confirm, this is after you have flashed the hacked firmware? Is the range affected (only 75% of the range?).

[@zannnewman3147]

[@zannnewman3147]

@@BananaScience ​ @BananaScience Yes, everything works perfect and 100% charge on the ES2's but my es4's will only charge to about 78%. If I take the external battery off I can charge the internal one to 100%. If I have both the internal and external battery installed, I can only get to like 78%. I checked voltage and I don't remember exactly off hand but 78% was not a display error. The voltage was lower than the ES2's showing 100%. I have swapped both internal and external batteries with my other scooters with the same results. I am thinking it's a BMS version problem. My batteries have mismatched versions but I don't know how to change them individually. I don't know if it matters but I also don't have windows 10 for the serial number change. Thank you again for your work

[@BananaScience]

Yeah it could be a BMS version issue. You can update the BMS firmware through the ninebot mobile app and then re-flash your hacked firmware afterwards.

[@zannnewman3147]

@@BananaScience Excellent, I will try when I get home. I was scared to install what Ninebot called the "master software" version 1.4.1. I didn't know if I could go back to hacked software after I updated or not. Also, do your LED's on the bottom work after the hack flashed install? One of my Es4 work but the other does not. I have researched and from what others say, it has to do with the serial number.

@BananaScience is N3M-Ninebot-M the correct Name after flashing. I am asking because I cannot change the name no matter if I use Android or IOS. Forgot to write down the old bluetooth name beforehand.

[@BananaScience]

Florian Pust For some reason on certain ESCs you can’t change the name over Bluetooth and will need to connect to your ESC via ST Utility and locate the hex address where the name is stored. See our ESC flashing tutorial for more info.

[@Antassium]

I got this error when connecting to a newer model without flashing. I'll be trying the firmware update when my ST-Link comes in.

[@eaglez4242]

Could you ever do this without soldering? If I buy an oem dashboard, it will have the original ninebot software so I could just install the hacked software?

Yes if you buy an OEM dash but even some that claim to be OEM aren't OEM. (plus it will cost quite a bit more). You can do this without soldering if you have a friend hold two multi meter probes in place and stick the other two power probes into the red and black wires going from the throttle or brake connector.

[@eaglez4242]

@redwan TANGER so what I did is I bought a CLONE dash to replace the gps block for my es2 and it for the past 40 miles has worked fantastically. If you want to switch modes from sport you have to buy an OEM control board

Hello want to ask you, can i do it with mac pc or only windows. And another question. The usb key you have, its a special one or can i buy it everyplace?

[@BananaScience]

You can buy the ST Linker USB device from the link in the description below. You can use mac to do the ST Link flashing (terminal code is a bit different so make sure to check the website where I copy the commands from for the mac version) but you will need to use an android or windows to upload the stock firmware. You could boot into windows on a mac using boot camp though which should probably work.

[@darrengreene-wynter5296]

can I do this with the dashboard on the jump scooters? Also how would I get stock firmware on the ESC of the bird scooters. I heard that they now have custom firmware

[@BananaScience]

Darren Greene-Wynter this will work with any ex rental scooter that utilizes Ninebot ES/SNSC hardware (note some things may need to be replaced) Yes, the new BIRD scooters are using proprietary firmware on their ESCs but it can be removed via flashing stock firmware using the ST Link. Please refer to the scooter hacking forums for more details on that. (See ninebot section about error 10) This does involve completely dismantling your powertrain, however, and if you just don’t want to have to go through the hassle of flashing the ESC you can just buy a new one online (note you still will need to dismantle your entire powertrain to install the new one)

[@mr.jimbusiness6326]

Is it possible to pay you to do this if I send you several dashboards? Just the dump, I can do the Bluetooth part

hello I found a VOI ninebote rental, what is the best way to use it, what do you recommend?

[@BananaScience]

Assuming you attained the scooter by legal means, you will first need to determine whether your scooter has the tracker board mounted on a front facing pod or on a box on the handle bars. If it is in a front facing pod, you will need to buy a replacement electronic speed controller (ESC) and remove the tracker board as well as flash original firmware to the upper dashboard. If it just has a tracker box on top, you will need to remove the tracker and purchase a replacement dashboard. Let me know if you would likes links to purchase either the ESC or replacement dashboard.

[@currenlydying]

Hey, i live in small town near Paris and sometimes rentals just get thrown here somehow, I don't neven understand how because it's actually pretty far from paris, it's like 45 min by car. But yeah they just end up in the town landfill or like a flash one, in my yard, because someone thought throwing one in my yard was fun or smth i guess. So i decided to poke around in it to see, since i'm not driving 45 min to put it back into paris, and at first i wanted to totally change the esc and dash for non ninebots one. But then learned that you might be able to just flash a voi to unlock it. So if i follow your instructions do you think it would work? Or would i have to buy a new dash for some reasons? I mean i already ordered the thing to flash cause it's still a fun project on the side to see if i can make it work haha.

[@currenlydying]

Ah yes, also, do you know ways to get good deals on ninebots? I'd like to buy one and I thought about buying a broken one and repairing it. Do you think it's a stupid idea or are there better ways to save a bit on the price?

[@BananaScience]

Nichatte you’ll still likely have to replace the ESC as well as flash the dash. Check out the forums in the links provided for more info on that. Regarding scooter sales, you can sometimes find a local auto auction that sells them by the lots of 10 as they were illegally parked then impounded. Other than that you can buy cheap parts online but they are likely stolen.

[@currenlydying]

@@BananaScience Thanks a lot, i'll work on it this week end, i found out that i could buy some from the trash place, if i manage to make the one i have work i might pull the trigger on them :) Also i read that you were working on a video about converting non foldable scooters to foldable, i'm looking forward for it and i thank you for your work!

[@BananaScience]

Likely not as the process is almost identical to this one except you need to just transfer the CFW file to your phone instead.

[@benjaminschutz727]

From my research, I wasn’t able to change my serial number via Bluetooth, I think it requires the st-link to disable that, if the 4th digit in the Serial is an R, then it is stuck in rental mode with only 1 speed setting. However in curious if it will work via Bluetooth if you remove the c15 Bluetooth refresher chip

[@BananaScience]

Krzysztof Kaminski I haven’t had that issue personally but since it’s already not working I doubt CFW would hurt and the worst that could happen is you need to use the ST Link to flash OEM firmware. I would say CFW is worth a shot

R Escue I’m not 100% sure if flashing OFW will fix your issue but I think it’s definitely worth a shot. If it’s stuck in limited mode, you might want to look into changing the serial number as that will unlock all the different modes.

Heya, did as the video and flashing the dash was no problem. However afterwards the dash doesn't turn on at all, i'm thinking maybe i have to flash the control board aswell before the dash comes on? The scooter is on, and flashes it's lights when i move it, just no connection to the dash and doesn't show up on bluetooth or in the flash-app. I've soldered on the STlink to the control board now thinking it's a similar process flashing the control board, you have any experience with flashing the control board through ST-link? The commandos for flashing the dash doesn't work here.

[@BananaScience]

Victor Ivering Yeah the newer rental scooters are using proprietary speed controller firmware that needs to be reflashed. We haven’t yet needed to flash a controller but someone is sending us one in the mail to make a tutorial video. If you want, you can ship us yours and we can flash it for you once we make our tutorial. Email us at [e-mail] for details. Otherwise, check out the section in the forums that says “error 10” and it will explain how to flash your controller.

[@operadores2]

hello why it has to have external battery to use this procedure?

[@BananaScience]

Hacking the firmware increases the amount of power drawn from the battery. Without an external battery to share the load, this increased current will fry your BMS (battery management circuit)

Yup. you probably have a Spin dashboard which doesn't turn on because of a custom firmware they install on it. Not only will flashing custom firmware allow you to use a higher top speed, it will also make your dashboard light up and work normally.
