Xiaomi MI Pro 2 (2022) - Unlocking Speed Limit to 25km/h: How to Bypass/Unlock Scooter Restrictions

Question

Hello, I have a question, namely I plan to buy Xiaomi MI Pro 2 from 2022, and from what I've heard with newer scooters from Xiaomi it's a problem to unlock them up to 25km. Unfortunately, I do not know if this is true, so I would like to make sure and if there is a way around it, I would like to...

I didn't know what the name extension with NE means, but if they are any design corrections or equipment additions, the unlocking method is the same as in PRO2.
The fastest way is to replace the motor controller (DRV) in the platform with one with software from Pro1.

Buddy Jarroq - don't write if you don't know, your advice is HARMFUL!
Unfortunately, the approach to PRO-2, as to PRO, ends with an invariable message e27 and E35 - then often even ST-link no longer sees the controller and in no way can it be moved!
Of course, unlocking the PRO-2 is still fully possible, but it requires a bit more knowledge and experience.
To start at all, you should prepare a second dashboard, preferably the one from m365
If I remember correctly, new dashboards send a compatibility bit to the controller, if it is incorrect, it blocks the controller.
The second thing is that the drivers of the A and B series behave differently ;-)

Did Pontiko get stuck on something like that? I give advice based on my knowledge and experience.
I haven't come across any bit of compatibility so far.
I made maybe 10pcs PRO2 with my "harmful" method and they drive without a problem. And this on the latest BLE update without any BLE modification.
As the MCU in the DRV is blocked, I just replace it with a new one and program it or replace the MCU from another board "after transitions".
Error 27 on an unlocked MCU is just a piece of cake and is not a problem for me. Like BMS errors 21, 22 and 23.

You just need to have a little more knowledge and have more equipment than just ST-LINK.

Hello I am interested in modifying the mi pro2 tz to increase the speed.

Buy a display from Allegro for PLN 100.
It helped me. I was looking for a solution for half a year on how to unlock the Xiaomi Mi Pro 2 scooter. If you want to not lose the warranty, then keep the original display. If the warranty is necessary, then you change the display to the original and restore it to factory settings in the Mi Home application.

Replace the steering wheel even with xiao365 but first you need to change the softa in 365 because it will not communicate with your controller and the important thing is that you must have the controller in pro2 V3.0 above it is impossible without the programmer. I modded mine and even 4 jets went empty under load 36 -35 flies normally. That’s it and the rest is up to you what you do with this message. And those who make secrets from it count on money from those without proper knowledge. Good luck and wisdom on the path. Increase the battery capacity because it discharges 2 times faster 😀

It's all about playing with the currents... As long as you don't fry the engine. Added after 2 [minutes]: Unlikely at present. For PLN 100 you can buy a blocked or clone that does not program at all because it has non-factory counterfeit soft.

Maro6950 · Answer

the engine is not even warmer than the tires after 8km. The son of a good softa threw it and it's ok, in the pro two there is a 600watt engine so it can withstand it without any problems

jarroQ · Answer

600W yes, but it's not continuous power. The motor housing is much cooler than the stator. It really doesn't take much to lead to the situation as in the picture above. The current can be increased by 10-20% without any problem. However, if we increase the current by 40%, we already fry the insulation.

Jarroq and how much does such pleasure cost? Just out of curiosity

Hello.
Is it possible for someone to further develop a way to unlock a scooter with a replacement handlebar? I have a pro2 scooter from 2020, which is unlocked, and I am trying to unlock the same model from 2021. I purchased the xiaoflasher program, but unfortunately the driver does not want to accept the unlocking.
From what I remember at the moment, it looks like this:
DRV: 2.4.8 BMS: 1.4.1 BLE: 1.5.7 and I cannot change the drv to a lower one.
Edit: I disassembled the platform today and unfortunately the controller is v3.1.
