Hello, just did the no soldering because i didn't want to go to work for it, and well everything worked. So thank you very much
Muito Bom seu tutorial , muito bem explicado ! congratulações ! Meu scooter Xiaomi essential deu Bug após uma atualização errada e a Dashboard não ligava mais, somente piscava a luz de freio quando apertava o botão power. Mesmo assim consegui realizar o downgrade , sem precisar realizar soldas, mas utilizando fios de metais de pacotes de pães. Consegui na segunda tentativa graças ao excelente video e as excelentes explicações .Você me fez economizar 60 euros . Muito obrigado . From italy
Que bom que foi útil. Não se esqueça de se inscrever, obrigado :)
Seriously, I did this thanks to your tutorial! But without soldering. Thank you so much 🙏🙏
Cool :)
can i use this on xiaomi scooter 4 go

Thank you for this tutorial, my scooter just hit 2000km, so as a reward i downgraded ble so i could flash custom firmware. No soldering required, took a couple of attempts but now my scooter has a new lease of life. Appreciate this tutorial.
Nice work! Don't forget to subscribe, thanks :)
Great guide, many thanks!! It helped very much in 1s firmware downgrade
Just a few notes from my experience (maybe helpful for others):
1) From MiDu flasher I was not able to automatically download BLE and Bootloader firwmare, but I just had to manually download them from the links provided by MiDu, rename donwloaded files according to names indicated by MiDu, and paste them in the folder required.
2) At first I tried to solder the STLINK wires to the board, but MiDu was not able to establish the connection (and I also did a little damage to the scooter screen) -> this was because I made bad soldering (which I found harder than I thought)
3) So I ended up trying the "no solder way" and, after a few attempts, I succesfully established the connection and updated the firmware -> so I consider this solution even "safer" if you are not so used to solder :D
Thanks for the feedback and for sharing your experience.
And don't forget to subscribe, thanks :)
so this just flaseha the ble to a version lower than the 157? my references are,1.1.0_248_157_141. I'm waiting for the stlink. In the microcontroller option I have to choose the one above since my board is the orginial no and once finished this flasehar completely with the DonwG to reinstall everything complete in the version of drive bms and ble that I want via bluetooth?
HOW DID IT WENT?
Thank you very much bro, love from Greece 🇬🇷!!

I do everything, remove and C2 but still not get connections . Same STL i use for repair bricked ESC. Checked all 10 times not error in my cables but not connections on 1S :(
You're a ⭐️ I just can't wait to receive the st-link and I do all this! Danke Schoen!😜

Worked like a charm. Used a very thin wire (0,5 mm) which was easy to solder on the pads. Also used my glue gun to glue the wires down at the edge and that made it easy to remove afterwards. Subscribed.
Nicely done :)
Thank you so much for the tutorial. I managed to downgrade BLE. I want to change scooter configuration using SHU to adjust cruise control activation timer.
Taip, shu geras pasirinkimas as taippat ja naudojuosi.
My stlink cables didn't come with an end that has pins. My cables have holes to be plugged into something on both sides, as if I'd connect them between two stlinks. What can I do?
Cut a paper clip or something similar made from metal, or buy those pins in any local electronic DIY shop. Subscribe, thanks.
Would this method also work on a segway ninebot G30LD? Assuming I flash it with ninebot software of course. The dashboard chip is the same, all the numbers match on the chip as well. All I could find about the G30LD is people soldering straight to the speed controller, which requires a lot of disassembly.

Hi I tried modding my xiaomi essential to make it go faster but now all it says is error 27 control code error, I looked it up and it says that I have to change the motherboard, is there any other way I can solve it? like with the st link?
Probably your ESC board is 3.1 with a new microcontroller (you needed a different type of DRV). You can recover your mainboard (ESC) with the stlink.

Hey I got a problem. I did every think whats in this video and when
Im trying to downgrade my scooter ( pro 2 ) it says error no connection, adapter speed= 1000 or 400 or 100. Do you have any solution for this?
Poor soldering or incorrectly connected wires to stlink. Subscribe, thanks.
I have a question regarding the serial protocol used by the USB ST-link
What protocol does it use for communication:
UART
I2C
SPI
CAN
GPIO
I believe it uses SWD/JTAG debug protocol
and GPIO communication interface
I'm not sure that I'm correct if you are really interested in this you can ask VooDooShamane at rollerplausch.com/threads/midu-flasher-st-link-downgrade-unbrick.5399/ forum.
Hi, can I use this software when connected directly on ESC? Because I dont have serial number, scooter is bricked and no sticker on outside...
No, this is currently only for ble unless a new version is out.
Take a look at this telegram chat t.me/scooterhackingchat there are many serials in pictures.
Maybe a random number after the model number would work too, haven't tried it.

Hello !
I have a mi pro 2 with:
BLE 1.5.7
DRV 2.4.8
BMS 1.4.1 and i have the new 3.1 controller...
so it is possible for me to downgrade BLE without bricking?
and if yes, what kind of (speed) modifications can i do with the new Controller? i would be thankful for an aswer!
You can downgrade BLE regardless of your ESC controller (they are on different boards and use separate firmware).
As long as you have ESC3.1 you need a different DRV than those old ones, otherwise, you will brick your ESC board.
Here you can build a new DRV by yourself:

No, kill all apps on android and re-enable bt connection. Or restart your smartphone.
To connect to mihome, you need to remove your scooter from the app and connect again like the first time. (this happens every time you use a third party app). Subscribe, thanks.

Did you check your ESCversion?
You can check your ESC by the app: "m365 downG " look in the UUID under Tools. If the UUID does not contain FF characters, it is the new controller.
If the UUID contains the characters FF , it is the old controller.
I think you have that 3rd version and need a different DRV.
Ask in this forum, there is a link to a web builder for the 3.1 controllers DRV, you must build it by yourself. rollerplausch.com/threads/neuer-controller-v3-1-bei-aktuellen-xiaomi-rollern-brickgefahr-bei-drv-downgrade-vorgehen.5187/page-6#post-67651
Or ask for help in this telegram chat, this guy has already prebuilt DRV's for the 3.1 controllers.

Tengo el pro2, con 157, 248, 141. ESC ver 3, hice el video de sin soldadura.. Hice el flasheo solo del BLE y después con DownG le puse la versión 2.2.3 original y todo perfecto, después de comprobar que mi placa ESC era la versión 3. Con DownG herramientas comprobando que están las FF en la numeración y todo perfecto gracias.
Encantada de escuchar que fue exitoso.
Hi. New to this. BLE = Bluetooth firmware right? But what is the ESC and the BMS referred here? Is BMS= firmware version?
There are 3 components that have firmware on them, and you can flash them separately.
BLE = Bluetooth/Dashboard unit or its firmware
ESC / DRV = main board/motor controller or its firmware
BMS = Battery management System or its firmware
Subscribe, thanks.
Hi Mindaugas ! Thank you for all you do for the community ! Quick question for 1.5.8 BLE DRV 2.5.2 BMW 1.4.1 is it still working ?
According to the app developer, nothing has changed with the new BLE158.
Still same procedure.
Sub. thx.
Does the downgrade apply to the dashboard or the controller?
I broke my dashboard during this process because the SWDIO dot came out of the board when I attempted to desolder and resolder as it wouldn't turn on when I soldered the stlink on. Will buying a dashboard off ebay be already downgraded? I'm going to try taking my pro 1 dashboard and putting it in my pro 2, but I am unsure whether it will come with the hack I put on my old one and whether the pro 2 will still have it's features like cruise control. Or the dashboard is simply just a signaller and display?
Downgrade applies to the dashboard. After the dashboard downgrade, you can flash firmware to the mainboard over Bluetooth.
From eBay, probably it will be a Chinese clone dashboard (unless you find the original). Some of them can be used for flashing DRV; some not.
If the problem is only that your solder point came off, the wire can be soldered directly to the PCB trace.
As for the pro1 dashboard, it will work with pro2, but the hack will remain on your pro1, as speed increases when you hack DRV mainboard.
If your pro1 has unlocked BLE (dashboard), you can use its head to flash shfw and then swap back heads. The dashboard is like a gate that lets you flash the main controller.
ruclips.net/video/YAexlwq47q4/видео.html
Check the video description.
If you follow this video, there is no need to flash the BMS; I just showed that it is possible. Only swap heads, and flash shfw from the "scooter hacking utility". After that, configure speed curves to start riding.
Hope it's more clear now :)

@@MindaugasJocionis thank you for your reply, it has certainly helped clear a few questions I had. The pro 1 dashboard swap didn't work out for me but I can't remember what the issue was. I bought a new pro 2 dashboard from Amazon for £23 and was able to use the hacking utility to install the hack. It was much easier than trying to solder the tiny connections on the dashboard, so I'm glad I was able to do that. I needed my scooter to be able to accelerate from 0mph as I use it for carting dog crates at dogs shows too, and had Crufts just days away. I fortunately fixed it in time :)
I still need to figure out why my pro 1 won't turn on, but I have a spare dashboard now as I also got one from ebay, so I will test that out. I tried replacing a connector for the brown cable from the battery to the controller as it looked cooked, but that didn't fix it.
Glad to hear that you fixed your scooter . 👌
Hello ! I have BLE 157, BMS 141 and ESC 321, can I downgrade safely with your technique or is my ESC version too high and it will brick if I do anything ?Thank you !
321 is your DRV, not an ESC version. You can check your ESC manually by removing the bottom cover and taking out the mainboard - ESC (electric scooter controller) or by the app: "m365 downG " look in the UUID under Tools. If the UUID does not contain the characters FF , it is the new controller: Flashing the old DRV leads to Brick !!
If the UUID contains the characters FF , it is the old controller: no problem with flashing.
Even if you have a new ESC 3.1, you still can downgrade BLE as in this video, as it has nothing to do with your mainboard, it's a dashboard downgrade.
For ESC 3.1 there are different DRV (still in early stages).

Yes. BTW after BLE downgrade, before flashing DRV ,check your ESC version.
If it's 3.1 you need new gen firmware.
For Mi3 before flashing hacked DRV it is necessery to downgrade to DRV003 at first. After that you can flash any DRV.

You can use any metal that fits: paper clip, paper pins, etc.

Hello, i have a Xiaomi Pro 2 Scooter and my original dashboard is dismantled or removed from the scooter. Is it possible - without any power source - to flash the dashboard? The only energy source would then come from the ST-Link. Btw the dismantled dashboard is easier to solder and to connect to the ST-Link and computer. What should I do? Better mount the dashboard on the scooter or is the alternative way possible (dismantled dashboard)?

I did it in automatic mode...
Subscribe, thanks.
Ok thanks! It worked once I stop my antivirus 😅😅
Ok so I did this *WITHOUT* soldering, like you showed in the other video.
DON'T PANIC if you move the cables while flashing. It "soft locks" the scooter, but all you need to do is unplug the board (by removing the scooter "head"/steering wheel) and then replug it. You'll then have to reconnect, your scooter will appear as "Empty Flash" or "Flash", something along those lines, at which point you should be able to connect and unlock it (if you locked it). Then, try again. It doesn't just "brick" your scooter.
If you have a Pro 2 like me, you'll have to cut a little thing (check the "Doc" folder, "Diagram" picture). I just used a little exacto knife thing and just ran it through that.
I messed up 3 times, soft locking myself, and retrying, I got it on the 4th attempt and everything was good, thank you for the video
Thank you for sharing your experience ❤
It's valuable, especially for those who will do this in the non-solder method.
As for the capacitor, definitely, it won't make it worse if you cut its track (it's just a matter of warranty).
A few subscribers reported that they flashed pro2 successfully with untouching capacitors.
So I think it's just a matter of good contact.
Personally, I practiced a few times in "Dump Flash" mode to get the feeling of needed pressure and position of the pins. After that managed to flash 2 times in a row from the 1st time.
Subscribe, thanks.
Today I cut out 4 pins from an old IC solder socket and soldered that to the display board. This way I now have a permanent plug-in connection for the ST-link. Good for playing around or if you will use the board to flash other scooters etc.
@@juleol99 Very cool. Subscribe, thanks.

Hi do i need to remove some capacitors for this to work or i just directly go to soldering? Thank you!
There is no need of removing capacitor or cutting trace, stlink will connect @ lower speed. Subscribe, thanks.
Will it work on a xiaomi electric scooter 3 2022 version (max speed is 20 kmh)? And how can I check my BLE, DRV and ESC?
Yes, it will work, you need to choose mi3 in the scooter selection option.
You can check your ESC; DRV; BLE; BMS with "m365 downG "
As for the ESC version: in m365 downG look in the UUID under Tools. If the UUID does not contain FF characters, it is the new controller. 3.1
If the UUID contains the characters FF , it is the old controller. 3.0

with:

What can be done in my case ? ;/
Thx and regarding
I don't have experience with these older models. If it's the original dashboard you don't need stlink, as m365 pro does not have BLE that is unflashable with BT. Follow this guide: www.monopattinoitalia.it/miglior-firmware-xiaomi-v2/ (use google translate)
In addition to DRV, you will need to flash BLE that is prepared for the new DRV version.

Hi. I have a m365 and I flashed via Bluetooth BLE129 that I downloaded from scooterhacking. After flashing it the scooter simply disconected from my phone, the battery level dots went dark, the button didn't work and it started behaving like it was blocked. It also doesn't appear when i search for bluetooth devices.
A few hours later it stopped behaving like it was blocked and now it simply blinks the tailight when the button is pressed. Thats the only response that I can get from the scooter. The rest remains the same except that it doesen't block the wheel when its moved anymore.
Do you think that doing this procedure would solve this problem?
Probably yes, choose write flash instead of downgrade in the midu flasher. I believe to use shfw on m365 you need modified ble "BLE90For4dot_zipv3.zip" it can be found in this telegram chat: t.me/scooterhackingchat

I don't have the tips you put on the wires what do i do
You can find them at any local DIY electronics store, or check out the affiliate links in the video description. Or use any suitable metal, such as a cut paper clip.

Thanks for this guide, i downgraded my 1s without the soldering and flashed a custom firmware, fully charged i reach 30kmp, is there any way i can go faster?
Only with the "field weakening" option from the "scooter hacking utility" app. Though I don't know the safe values to avoid burning the motor. I tried with my Mi3, reached 40km/h, and the motor was hot to touch after 2km. So... Subscribe, thanks.
Perfect thx mate your welcome you vid is gorcieous
Sub. Thx. :)
Hey i did this and i use the no soldering method but it went off the pins a few times then when i finished it, ir works but it shows an error 42
Mi scooter 3? Did you flashed some DRV? Install shfw from "scooter hacking utility" and configure it. Check this telegram chat for moore info t.me/scooterhackingchat
Sub. thx.
@@MindaugasJocionis Yeah i have a Mi Scooter 3 and i downgraded it using the no soldering method and it did show error 42 but when i flashed it to install SHFW with Scooter Hacking Utility its fine now, Thanks for the great video
@@mohammadannasnadeem5281 Nice :)
Hello, thank you for your video.
I have a BLE 158 and I am unable to establish a connection to the scooter. I am waiting until a speed of 100, but without a success. Could this connection problem be because of the higher BLE version of 158?
I tried with the both midu flashers.
Thanks!
Did you checked for continuity with multimeter 6:06 Probably a bad contact.
Subscribe, thanks.
@@MindaugasJocionis yes, I did..
My st link has another schema, I am connecting them according to my schema. 2-SWCLK
4-SWDIO
6-GND
Could this be a problem?
@@MrGeorgimavrov I will text you on telegram
amazing video bro! Sorry, One question: in the program support the mi scooter 3? i have the same u dashboard
Thanks. Yes, miduflasher supports mi3 scooter. Don't forget to subscribe :)
Do I have to solder it and if not, I have to redo these wires somehow? By that i mean 4:27 process
You can do the same without soldering: ruclips.net/video/NYxrvGhevwg/видео.html
Or after the downgrade, you need to desolder those wires 10:33

Dzięki za fajny filmik w którym wszystko szczegółowo opisałeś. Dziś zobiłem downgrade majej Xiaomi M365 Pro2 w której po zakupie w maju 2022r. zaktualizowałem oprogramowanie przez oryginalną aplikację MiHome. Wgrało mi BLE157 i nie mogłem modować bez podmiany kierownicy od znajomego. Dziś dzięki Tobie mam BLE 134 i mogę swobodnie testować różne wersje DRV. Sterownik oczywiście oryginalny z maja 2021r. Jeszcze raz dziękuję i Pozdrawiam.
Dzięki za tak pozytywny komentarz. Cieszę się, że się udało. Nie zapomnij podpisaćsię. :)
Też mam BLE157. Muszę sprawdzić czy mam w skrzynce akurat ten programator. Jeśli tak to zaraz to zrobię, a jeśli nie to lipa, bo muszę zamówić i czekać.
Zamów w Polsce będzie szybciej niż czekać z aliexpress
@@MindaugasJocionis właśnie chciałem pisać, że nie mogę znaleźć żadnego, ale ST Linka chyba nie miałem, albo już dawno przesiałem, więc zamówiłem. Jutro będzie 😁
@@MindaugasJocionis ogólnie z Aliexpress zamawiam jak mi się nie spieszy i jest dużo taniej lub nie ma tej rzeczy gdzie indziej, a i tak staram się zamawiać z wysyłką tak by w maks 1-2 tygodnie było u mnie. Tutaj nie będę czekał dla oszczędności kilku złotych, zwłaszcza, że mi się spieszy

Merhaba, bu yöntemi ben de yapmayı düşünüyorum lehimlemeden yapmışsınız sanırım dikkat etmem gereken bir husus var mı acaba ?
Ek olarak downgrade işlemi sırasında bağlantı koparsa tekrar başa sarıp downgrade yapabiliyor muyuz?
@@BaldwinnIV lehim yapmadan doğruca üstünde tutarak yaptım. Eğer temassızlık yaparsak el titremesi vb sonucu herhangi bir sıkıntı olmuyor, programı baştan açıp daha dikkatli tutıyorsunuz. 5. Denemem civarı başarıya ulaştım

Hello please help. When i am in the part of "press any key to continue" , there in an error "could not download file.
Pc must be connected to the internet, as well as disable antivirus or firewall (if using 3rd party). If that does not help (might be FTP server is down etc.) Do this:

Hello Sir
My scooter
BLE is 1.5.7
Drv STM32Fl 2.4.8
Uuid contains letter FF
Can i flash it by changing dashboard ?also if yes will i be able to use extern battery like i did my old scooter xiaomi pro2 ? Thanks in advance sir
Yes, you can flash any custom firmware to the motherboard after a dashboard replacement or ble downgrade. Whether an external battery can be used depends on the firmware used.
For more information about external batteries, please contact this telegram chat:

As I personally hawe zero experience with external batteries.

Hi, my friend has a pro 2 mercedes version drv: 155 ble: 157 and he flashed using downg without downgrading ble with a file called "Drv_233_Pro2_StockFW.zip" Will this brick my pro 2 (ble 157 and drv 233)?
Until BLE157 is not downgraded, nothing can be flashed. After flashing the firmware will remain the same as before flashing.
@@MindaugasJocionis Is it safe if i tried flashing this file on my pro 2? Hes been teasing me to do it because im terrified about my scooter getting bricked, i don't know how his scooter actually goes 33 km h/
@@asid.6642 You can brick your scooter while flashing DRV made for ESC 3.0 to ESC 3.1 What is your ESC version?
Download the "m365 downG " app and look up the UUID under Tools
If the UUID does not contain the characters FF , it is the new controller 3.1: Flashing the old DRV* leads to Brick !!
If the UUID contains the characters FF , it is the old controller 3.0: no problem with flashing
@@MindaugasJocionis It has FF so i can try to flash and no harm will happen?
@@asid.6642 Yes you can try.
Hi there.
I'm here with a problem I encountered. Basically I successfully connected the st-link to the scooter. Did everything right but when it comes down to the Midi flasher its not working properly.
Started the program, choosed the corresponding options in it and didn't thrown any unexpected error when I started. I did not cut the connector to the condensator and waited the 5 error.
When the Midi Flasher lowered the speed to 400, there was a weird thing. The program said its connected, its shown as connected but after a second or so the error that it cant connect came up like when the speed was too much. I think'ed it's a problem like so and waited. The program went from connected to error and so on till it reached the point to lower the speed more but now only just the errors popped up.
I tried to resolder it 2 times and did not worked. Tried to change the ST-Link firmware or reinstall the whole thing but that did not worked either.
I don't know what's the problem soo that's why I write this :D
I have a Xiaomi Pro 2.
I hope you can help me or someone and thank you in advance :))
Try to ask for help in this telegram chat t.me/scooterhackingchat
Did you checked for continuity with multimeter? In my opinion it's bad connection.
Subscribe, thanks.
Yep I checked for continuity and it was ok.
Maybe going to try again with a better solder because mine is like a cheap one XD and with better equipment for soldering.
Hi there. I had same problem. What helped to me? In Select an Action I tried to choose "3) Write Flash" instead of "1) Downgrade" and it works. Now I have BLE 134 on my Pro 2 and back my custom FW (flashed again).
Hi sir, i just ordered an st-link, but i have ble 3.1 board, can I downgrade it with scooterhacking reflasher?
BLE board 3.1 or ESC board 3.1?

@@dog_ds I think it should work, ask in that telegram chat I provided earlier.
@@MindaugasJocionis okay thank you sir
Matau lietuvis gal zinai kur isigyt st link arba gal galetum padaryt uz minimalia kaina ?
When i try to Flash it the software just keeps saying error pls help
If you soldered it, it means there is a bad contact or the wires are connected incorrectly. If you're just holding these pins by hand, clean the protective coating off the circuit board with isopropyl alcohol and hold as steady as you can. Subscribe, thank you.
There is 2 Links
One is STLink - v1.0.4
Another is STLink - v1.0.5
Which one should i use plz reply
Use V1.0.4 If you will have some issues with it, then use V1.0.5

Hi, i just downgraded the BLE to 152 on xiaomi mi 3 and it shows error 42. I realy dont know what to do. I tried to flash the firmware using scooter hacking but it didnt work. Any time i tried to flash it, it "crashed". Scooter turn on while the firmware was uploading and make a sound. Thanks for any advice ! 🙏
DVR 317
BMS 1702
BLE 152
Check your ESC version if it's 3.0, then flash DRV003
files.scooterhacking.org/firmware/mi3/DRV/
After that, you shud be able to flash SHFW
If ESC is 3.1 try asking in this telegram chat t.me/scooterhackingchat
as I don't know for sure that ESC 3.1 supports DRV003
Subscribe, thanks.
@@MindaugasJocionis Thanks a lot you save me !! It worked.
Glad it worked :)
Can I downgrade to hack the speed as my scooter configuration as mentioned below?
DRV Ver 248
BMS Ver 141
BLE Ver 157
UUID 48FF70068------1067
And one more question is, Can I replace the dashboard instead of doing stlink? If so do I need to do something with the controller?
Thanks in advance….
Thanks in advance.
Yes, you have ESC version 3.0 so any DVR is compatible. And yes, you can downgrade the BLE version as shown in the video.
As for the dashboard, if it is original, then it should work out of the box, if clone, then ask the seller.
Subscribe, thanks.
Can I downgrade with miduflasher also on the controller
You mean bricked 3.1 ESC controller?
Subscribe, thanks.
does it work with xiaomi mi pro 2 2022?
Yes. Subscribe, thanks.
Is midu flasher only for dashboard ?
No not only for BLE, but it must not be bricked. And if it's not bricked, there are more easy ways to flash DRV than soldering to ESC.
Thanks so much

They are all the same. Watch the video @ 7:01-7:04 to see where to connect the wires.

Also hauptsache die 3 gleichfarbigen connectors irgendwo in dem ST Link einstecken? Und wie nennt man diese Wire Tips in Deutschland? 😅 Dankeschön!
@@YogiMystic No, you need to connect those 3 pins on the dashboard: (GND; SWCLK; SWDIO) to pins on stlink with the same label. (there is a diagram on stlink).
I'm not from Germany :)
Oh okay, sorry for the confusion and thanks again :)
@@YogiMystic No problem :)
