Xiaomi scooter 1S BLE157 downgrade using stlink

[@fredricskogman2479]

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.

I have this problem: after soldering the stl to the board properly ( and checking)... the scooter doest turn on ( the tail red light blinks but nothing)...if I disconnect the STL programmer ( even just one wire) the scooter turns on normally.

[@giorgiofissore8416]

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

Hi dear I have the GD32E1 - V3.1controller is it work OR I will break MY SCOOTER

[@MindaugasJocionis]

This video is on how to downgrade BLE (dashboard) firmware. GD32E1 (V3.1) is your mainboard controller. So after BLE downgrade, you need to use DRV which is made for the 3.1 controller, or use SHFW from the 'Scooter Hacking Utility' app; it detects the controller version and flashes the right firmware

[@Vordie]

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

[@MindaugasJocionis]

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.

[@juleol99]

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.

If i do this what could happen in the bad situation, Could the dashboard break And do you recommend to try it on another dashboard

[@MindaugasJocionis]

Most people do this without soldering, just holding the pins by hand. (For this, you must clean the coating from those connection points with isopropyl, etc.). A Clone dashboard is also a good choice; use it just for flashing firmware to ESC. After that, you can switch back to the original dashboard. If soldering is a problem, I think the safest method is to use a clone dashboard just for flashing ESC. If you are considering soldering and doing this for the first time, I suggest you practice on some bad PCB from PC, etc. Usually, problems are related to soldering. (Burned PCB in soldering place, ripped off traces etc.) Subscribe, thank you.

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?

Hi I just want toshare my experience with this method, I flashed the scooter succecfully but I did NOT check my microcontroller. I still don't know which one I have, however I pressed the first option in the program when I was given the choice of what microcontroller I had. Everything seamed fine, until I flashed a custom firmware to increase the speed. I went for a ride and quickly noticed that the scooter would turn on whenever I tried to shut it off. I googled but could't find somone with the same issue, I then tried to flash back to the stock firmware with no result using my phone. I then tried to flash it using the st link with my original flash that I had dumped before flashing the first time. From there I was able to connet the scooter with the mi home app and uppdate the motherboard and once I had done that everything worked fine again. I want to run custom firmware in order to connect my batterypack but as I have mentiond this method did not work for me and I m positive that it has to do with the microcontroller, so I have ordered a clone motherboard with a diffrent microcontroller and hopefully it will run custom firmware succesfully then.

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

[@MindaugasJocionis]

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: t.me/scooterhackingchat As I personally hawe zero experience with external batteries. Subscribe, thanks.

Does it still work with the firmware version 2.5.2 and DRV ver. 252 / BLE ver. 158

[@MindaugasJocionis]

Yes it's the same on BLE158. Subscribe, thanks.

There is no need of removing capacitor or cutting trace, stlink will connect @ lower speed. Subscribe, thanks.

hey i flashed 2 scooter one xiaomi pro 2 nordic and one xiaomi 1s nordic .1s . i changed display to earlier than BLE 157 and i flashed both is hacked and driving fast works good but both when i turn they of they start by them self and they are not possible to turn of by them self please can you tell what i have done or what i should do to fix this ?

[@MindaugasJocionis]

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. t.me/STLink_XAP2P "Scooter hacking utility" is working for support for 3.1 controllers as well, but still it's a work in progress.

You were probably soldering while it was on. And touched something with voltage. Shit happens. Buy new dashboard.

Why it's not locking? Did you brick it by flashing wrong firmware? If so, you need to reflash tour ESC: kzbin.info/www/bejne/oZPNZHRqlqafibc Subscribe, thanks.

@@MindaugasJocionis no i tried to reconnect it to my xiaomi home app and i cannot do it

[@MindaugasJocionis]

If you have connected the scooter to any third party app, you need to first remove it from the mihome app and set it up again like the first time. Or lock it with "scooter hacking utility" app.

[@vfam825]

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...

[@MindaugasJocionis]

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. Subscrine, thanks.

[@ismaelpr1461]

Can this be done with a BMS over 1000 and a two lever Xiaomi 1S?

[@MindaugasJocionis]

BLE and BMS are independent parts. Just don't flash BMS. You don't need to touch BMS in order to achieve higher speed. BLE is your dashboard firmware DRV mainboard firmware BMS battery controller firmware As for compatibility with 2 brake lever scooter, try asking in this telegram chat: t.me/scooterhackingchat

You can recover your mainboard (ESC) with the stlink. Try asking this telegram chat group for help: t.me/scooterhackingchat Or this guy, he has recovery tools for 3.1 ESC board: t.me/STLink_XAP2P You have the 1st type of new microcontroller on your mainboard (ESC3.1 GD32E), you need a different DRV.

[@MindaugasJocionis]

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. Subscribe, thanks.
