Xiaomi scooter 1S BLE157 downgrade using stlink

[@anonutube3003]

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.

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.

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

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.

[@puntastic5710]

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?

[@MindaugasJocionis]

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. kzbin.info/www/bejne/j3LIqZ-tpplqp5Y 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 :) For more info, check this Telegram chat: t.me/scooterhackingchat Subscribe, thanks.

[@puntastic5710]

@@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.

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.

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 :))

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).

Hello, in some guides is recommended to remove the c2 condensator and R1 resistor (backside) in order to enable fw flashing… can you confirm that these steps are not really necessary?

No, it's not necessary. After BLE downgrade don't forget to check your ESC version. There are different DRV for 3.0 and 3.1 boards. Subscribe, thanks.

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 !

[@MindaugasJocionis]

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).

[@MindaugasJocionis]

There are no special conditions to downgrade BLE. All dashboards can be downgraded. Just do it step by step like in the video. I'm assuming you want to do a speed hack, for that you need to know the ESC version, if it's 3.0 then you're good to go. If it's 3.1, you must assemble your DRV (this is still in the early stages).

Sveikas ar imanoma kazka padaryti su mi scooter 3 su ble 157 ? Be litavimu ar ardymu?😊

Ne, na nebent laikinai sukeitus galvas su kitu paspirtuku, kurio ble neuzrakintas. Sub.. Aciu.

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
