Hey @GMOne ,

We were able to finally flash my friend's S2 and it has the new speed!! It took such a long time, and I almost lost hope, but with your help and some resiliency, we were able to do it!

I've sent you some coffee money as a token of our appreciation!

Also, I have a couple of tips, for those that may run into any similar complications in the future. With the Chinese J-Link V8 version that we got from AliExpress, you did NOT have to do any modifications. All the pins were already set to 3.3V, except for the 5V supply, but we were able to just use the Vtref pin which was already set to 3.3V. Make sure to use a meter to check the voltage to see what your J-Link is doing. If the voltage is correct, you can just connect the correct emulator pins to the proper connections on through soldering and that should work. 

Also, please use this https://j-link-arm.software.informer.com/4.2/  software to get the proper version of J-Link to use with your Chinese J-Link clone. This will prevent you from bricking your emulator like we did the first time. We had to buy 2 J-Link emulators from China which is why it took us so long.

Finally, the last mistake we made, was not carefully reading the settings for the Segger J-Flash ARM 4.2 setup. Make sure your project settings match the screenshot that GMOne provided EXACTLY. You will have to modify the MCU and a few other default project settings to make it match, otherwise the emulator will not be able to connect to the board. 

Hope this helps others in the future, and good luck!

GaperMaster  - could you please connect with my on email? I try to send to you message on that forum but it was blocked (i don't know why...). My email is luda@ikea.com. thx in advance..

Hej Guys,

I stucked in this moment... Any idea what next... pls..

 

[Darek Łuba]

Guys, pls... can you help me? I read whole topic to fiand similar problem but I didn't find anything like that.... Anyone? Is anyone outhere? 

Please...

Solder the power on the other side of the capacitor. Check the quality of the soldering.

[Darek Łuba]

You mean like that..?

 

[Darek Łuba]

I've done it like that:

but... this is the comment which apear..

Connect the programmer to your computer, on the board several diodes should light up and flash. Try to connect a mobile phone on bluetooth. If all is well, then check the solder swdio/swclk

Greetings to all. I am new to this forum. I only bought a mini-lite segway a few days ago and I find it a valid product but very limited in speed above all. Does Gmone's firmware work on my overboard? How to install it? Non soldering, I'm Italian, sorry for my bad English. Thank you

Hi @Darek Łuba I came back from few holidays... 😜

Did you solve the problem? Can I help you?

@Marco Roghi You cannot use my software, it is specific for S1 S2 (and it will check if the firmware is the proper one). But you can contact me and we can modify yours. Search my email into S2I app and feel free to write to me...

Ciao!

Is it possible to increase the current limiter? Since i’m Making custom batteries into my S2 (2x 15S3P 3500mAh cell batteries with (hopefully) new BMs-s that can handle 60A each plus a motherboard mosfet upgrade to handle more current. Also, is it possible to get the speed limit to let’s say 33km/h or 35km/h? Maybe 2 steps, so I could test it with my custom(ish) wheel and report back what happened? 

@Rocco Karson

MOSFETs can manage 60A, but it's not only a matter of MOSFETs. The circuitry and copper tracks and many other things... The motor (anyway I don't know its characteristics). There are many checks about temperature also. There are two resistors through which should flow the whole current. TBH I do not suggest to increase the current limit. The whole board would be overstressed for many reasons. It's a matter of security.

Anyway I could help you to do it, for me not much interesting and it not worth the trouble.

Into Speed2Increase there is the possibility to donate a lot of coffee ;-) Don't worry i do not risk to become nervous...! :-D

 

Thanks in advance,

Thanks, GMOne! Everything worked just fine! 

Ninebot One S2 speed limit increased to 30. Tested with GPS, it showed, that beeping begins at 26 km/h. Max speed registered - 27 km/h.

If there is anyone reading this topic from Moscow - I can share my j-link clone to flash your device! =)

(Если есть читатели из Москвы - могу дать погонять свой китайский клон j-link =))

Hi all:

First of all, thanks a lot for this great work. I'm trying to perform the mod in my S2 but it's the first time that I use the a J-link interface and I have an error message when I try to read the entire chip.

I have bought the Chinese J-link interface, the auxiliar board for the bridge and I have checked with a multi meter that the voltage is 3.3V.

I have welded the wires to the ninebot board and connected to the J-link as the attached pictures but I'm not sure if the Reset, CLK and DIO are in the correct pins. I have consulted the J-link data sheet but it's not clear for me.

I can connect to the J-link device successfully, but when I try to read the entire chip it fails checking the RAM adress.

Can someone help me??

Thanks

[MRN76]

@yoglorfindel Check the quality of the soldering. Pay special attention to pin reset.

[thebbum]

I have the Z10 but sometimes it's getting too slow for me. I want to increase my speed to 60km or remove the speed limit in general. Is that an option and what do I need to do in order to accomplish that?

[jackBoo]

I need some help from u, I used a j-link arm v9 trying to connect to my A1, but always cannot get it done. I use a version of 4.34 j-flash. can anyone share me a ver of 4.20a. I googled , and no results were needed.

sorry for my badly chinglish.
