Only for the brave. Russian Hack for the Mini Pro

Recommended Posts

Posted (edited)

I reached out to MRN76 today on Telegram and he helped me apply the Extreme hack. Went smoothly except for me forgetting to select my Ninebot from the menu and thinking the app wasn't working correctly.

The increased speed is very cool and it's nice not getting such annoying beeping and pushback. Still haven't hit max speed yet, so don't know what the pushback will be like. Hill climbing is where the new firmware shines. Previously I could only hit about 500 watts power, which on some hills means you're barely moving. I think I observed 1200 watts on the Extreme firmware, which is more than double the power. A steep hill where previously I could barely go up, now is no problem. I still haven't hit max power yet, so I'm not sure where the limit is, and I'm not sure I want to find out either.

One thing I just now observed (and probably not related to this hack) is that descending a steep hill on a full battery causes extreme pushback, likely because the battery is full and cannot accept all the regen power.

Regarding instability when slowing; that was a problem with the original firmware. Just the other day I was descending a very steep hill, and the thing got very squirrely, moving side to side despite me not touching the center stalk. Finally it got so bad it bucked me off. I can only imagine this behavior is exacerbated by having a higher top speed. 

I've only gone 2 miles so far on the new firmware, so I'll report back again when I've got more experience.

Following the instructions on Harishmirrors post, I just did the upgrade to MRN76 Lite firmware.

I first downloaded the NinetoolBeta app for an Android phone, connected and it got the necessary info from my minipro. Then I sent the info  to MRN76 by email and very soon after he sent details for a PayPal payment.
 

After I reported to him that I made the payment, he unlocked the Lite firmware in my app. Update went smoothly, all in all took just two minutes.
 

Now the minipro behaves like it always should have. I think it’s very much like how FreeRide described the swallowbot firmware. Top speed I got (according to the DarknessBot app) was a bit over 24 km/h and a subtle pushback and short beep comes up at around 22 to 24 km/h.

 

So, with MRN76 the service was fast and good, and in my opinion the firmware gives a sense of freedom and fun with less beeping, while still feeling safe. I just can’t understand why Ninebot didn’t make the settings like this originally, but anyway it’s good that at least now it’s possible to enjoy the minipro through these firmware updates.

Hello, sorry for jumping in here, but I wish if somone can help me, my Segway miniLITE was doing an update a couple of days ago, something went wrong during this process, during the process the scooter collapsed, red light in the back, battery led's are flashing, no power, and i cant turn it off/on. 

Can someone help to down grade or upgrade to make it work ?

If anyone is interested, I made a more extreme firmware. It has a speed limit of 25.5 km/h and power is greatly raised. But this firmware is not for children and not for beginners. I rarely go to the forum, it is better to write to me by mail or telegram.

 

Yes, I’m interested for a speed up of my MiniPro.

Please let me know what’s involved and I’m reached at rockyromero@att.net

This sounds a bit alarming to me. Is there a difference in this behaviour between the Lite and Extreme firmwares, or will they both turn squirrel on me in a steep decline?

I don't have lite to compare to. My assumption is the increased regen capacity results in exacerbating the squirrely behavior. I crashed going down about a 10% grade on the stock firmware due to pushing the limits of regen. With the extreme upgrade, it got even more severe and I crashed in about the same spot at a faster speed. The thing is, it can entirely be avoided regardless of firmware by simply going slower when you're on something steep.

After having put a lot of miles on the extreme firmware, I have noticed the squirrely behavior exhibits itself when pushing the limits of hill climbing, though it isn't as catastrophic (just back off a little and regain smooth control). It seems the extreme firmware allows the limits of hill climbing to exceed what is safe before pushing back.

On flat cruising, the speed limit will be hit and light tilt-back will occur before any instability is encountered.

Before the firmware update, I noticed push-back would occur after exceeding about 500 watts on a hill climb. On the extreme firmware, I have seen 1,200+ watts hill climbing with no push-back. Above that it gets a little shaky. In other words, the extreme firmware has more than doubled power for hill climbing, which was among the most disappointing thing about the stock firmware.

I'm getting a lot more use out of the Segway after the Extreme upgrade. It made shuttling camping gear from the car to the campground quick and fun. I'm able to push a stroller or pull a trailer now. I can ascend hills that before I couldn't, and at a much faster speed. Almost no accidental triggering of push-back.

I find this very Hard to believe ... I own the Mini pro Max and find it much more stable esp at high speeds ... The stock firmware has much more aggressive lean back without a doubt. I notice many people blame the hardware ... but usually 9/10 the user is just not adept enough.

I don't know what you're finding hard to believe, because the section you quoted is in regards to steep descents.

Have you ever gone down a >10% slope and pushed the regen capability? Others have reported the same behavior, so it's more likely you've just never pushed those limits.

If you believe going down an extremely steep hill faster results in more stability, I would like to hear what grade of hill you descended, at what speed, and your weight. All of those are factors in pushing the limits of regen.

Obviously a software hack only unlocks the potential of the hardware, as it has no ability to improve the hardware itself. That means it can only allow operation closer to the hardware limits. The implication is that there's more risk in operating closer to the limits of the hardware.

I've found those limits by crashing at the same same spot once on the stock firmware, and twice on the hacked firmware.

EDIT: I'm not convinced the deceleration wobble is entirely a hardware issue. It seems the wobble introduces a natural positive feedback response where weight gets shifted to one side, then the natural reaction is to over-correct to the other side, exacerbating the initial minor wobble. It could probably be handled better in software. That said, allowing stronger decel at faster speeds certainly increases the severity of the wobble and the resulting consequences.

... and it turns out the hill I descended with the sign that reads "Danger Hill" is a 13% grade. Probably rivals some SF streets.
