Magnus Posted March 30, 2017 Share Posted March 30, 2017 Hello I am a new ninbot driver and very happy. I also want to have the 1.3.5 again and have a question. Does all three lines have the same IP at ninebot.cn.prm? Mfg Wolfgang Quote Link to comment Share on other sites More sharing options...

Duc Posted April 4, 2017 Share Posted April 4, 2017 Hi, The one thing that I really don't like on my Ninebot C+ with firmware 1.4.0 is that it starts reducing the maximum speed already at a battery level of 40% and it becomes slower and slower from that point on, which perhaps is good for safety, but it is very annoying for me. Now that it is possible I want to downgrade the firmware, but I can't remember in which firmware version it was still possible to ride at the full 20 km/h down to a lower battery level. Does anyone know? That would spare me from testing all the available previous firmware versions. Quote Link to comment Share on other sites More sharing options...

Seems that they have reduced speed of P and C models in latest firmware... Quote Link to comment Share on other sites More sharing options...

Yes, I believe my C+ was on 1.2.0 when I got it and from then I went through every single firmware version that was released through the Ninedroid/Ninebot App until 1.4.0. I will try 1.3.5 and check what difference it makes. 1 Quote Link to comment Share on other sites More sharing options...
Vik's Posted April 13, 2017 Share Posted April 13, 2017 There is a new test version of firmware available for download (not through the usual app update), - 1.4.3 @MRN76 is working on an updated version of his Ninebot Degrader package. P.S. A little teaser: the new Ninebot Degrader package will include firmware "changer" for both Ninebot One and Ninebot/Xiaomi MiniPro/Mini and maybe (don't hold your breath just yet) will make it possible to downgrade mini/miniPro from newest firmware versions. 1 Quote Link to comment Share on other sites More sharing options...

The package is ready but unfortunately there is no way to downgrade mini/miniPro firmware from versions higher than 1.2.8 through the app... The only way is the hard(-wired) way - to solder a jtag programmer directly to the controller board. Still, the new degrader package can allow to easily downgrade from 1.2.8 to lower versions. I will post it here soon. Quote Link to comment Share on other sites More sharing options...

According to MRN76, on P model it gives a maximum speed >30km/h. Overspeed alarm beeping at 29km/h and tiltback doesn't engage before 30.8km/h (he didn't try any higher speed for safety reasons). Going down to 75% battery charge, tiltback being engaged at ~29km/h. The motor is not audible at all vs. v1.4.0 (dreaded 8kHz sound). Maximum cut-out speed (with the unit lifted up from the ground) - 39,4km/h. Other firmware versions have cut-out speed around 31km/h.

Vik's Posted May 21, 2017 Share Posted May 21, 2017 9BDgrader guide is now updated: Latest update includes downgrade option for Mini/Pro (from versions not higher than v1.2.8). Almost all available fw versions is there so it is possible to update your min/Pro to i.e. v1.3.1 There are also some newer Ninebot One firmware versions included. 1 Quote Link to comment Share on other sites More sharing options...
alcatraz Posted May 22, 2017 Share Posted May 22, 2017 All you E owners (non +), what is in your opinion the best firmware version? Which one has higher speed limit and less lower battery speed throttling? Cheers /a Quote Link to comment Share on other sites More sharing options...

When I have 9km left on my battery I'm stuck at walking speed for the rest of the journey. This restriction is too extreme. Quote Link to comment Share on other sites More sharing options...

Earlier fw versions are less restricted, probably. Edited May 22, 2017 by Vik's 1 Quote Link to comment Share on other sites More sharing options...
Saso Posted May 25, 2017 Share Posted May 25, 2017 When I install the 3.5.1 apk file on my Phone, it stops every time I try to open it. Does anyone know a solution for this problem? Does it also work with the 3.8.2 version? This is the one I had on my Phone and deleted. Quote Link to comment Share on other sites More sharing options...

Just don't use apps newer than 3.51. Quote Link to comment Share on other sites More sharing options...

What is the maximum speed for a E+ model with this Firmware? 1.4.3 is the latest testversion from Ninebot. Not made available for public install thought the app. Install at your own risk! Since the speed of P model with v1.4.3 is a little higher than 30km/h one can assume that E+ gets a little higher speed too (depends on your controller version). 2 Quote Link to comment Share on other sites More sharing options...
Hunka Hunka Burning Love Posted June 19, 2017 Share Posted June 19, 2017 Hey Vik's, do you know of anyone who has tried out the new firmware? Is there any appreciable speed increase with the E+? I wouldn't mind trying it out, but if it's not safe I think I'll wait for a while. I'm still on 1.2.5 which works well for me, but yes the 20% low battery extreme tiltback and limp mode home is annoying. Usually I can slow down enough to let the battery recover to resume cruising at a slower pace. Maybe it's best to leave well enough alone though I'm thinking. With an older battery, if the new firmware stretches out the limits, I'd be afraid of hitting complete cut outs especially if there are some weaker cells in the batch. 1 Quote Link to comment Share on other sites More sharing options...

You could update to 1.4.0. however, and be even safer than 1.2.5. Supposed to be safer than earlier versions. I don't know about that, mine will get up to 15mph without beeps or tiltback. Only tried it for a few seconds on a full charge. 1 Quote Link to comment Share on other sites More sharing options...
Hunka Hunka Burning Love Posted June 20, 2017 Share Posted June 20, 2017 (edited) I think Vik's is still on 1.2.2, and I haven't had any issues with 1.2.5 since I got my wheel. Usually I don't mind experimenting, but I also don't like to fix what's not broken. So far my rides hit about 17 kms mostly where I reach about 25% battery without any low battey tiltbacks so I'm quite happy with that. When I hit 19-20 kms is when it gets a little dicey. I see 1.3.5 is popular. I just haven't seen a lot of clear reasons to upgrade. Gyrometrics tells me I average about 20 kph over 17 kms with a high speed of about 26 kph. It sounds like most people average the same speed. It would be good to find a firmware revision table that details the changes made as it would be easier to decide whether to upgrade or not. That link in Vik's post isn't working. It's so sad that the Ninebot P was a flop. The extra speed would have been so nice to have. I wish Ninebot would come out with a new 16" wheel that can cruise at 35 kph, but has that rock solid dependability it's so well known for. Maybe the P catastrophy lost them a bunch of money so the bean counters nixed any new 16" wheels. After cutting off all their dealers, I wonder what they are concentrating on now besides the S2/A1 wheels. You just don't hear any developments from them any more.

I know that @MRN76 and some other russian guy got v1.4.3 but they are going all in with expanded battery upgrade and changing the serial number making E+ to a P model... So not too much useful info for those who only wants to try it on stock E+ I'm still on v1.2.3 and since that version is not a part of 9BDgrader I am a little hesitant to upgrade to 1.4.x without being able to go back to my original fw... 2 Quote Link to comment Share on other sites More sharing options...
