![[W600 / TW-03] Door Sensor - Bootloop on 1.18.110/109 Firmware](https://obrazki.elektroda.pl/5552096400_1749191730_thumb.jpg)
Here I will show you how to flash BK7231M chips (or BL2028N) with our open source, Tasmota-style firmware. BK7231M/BL2028N are very similiar to BK7231N, and the only difference in the encryption key stored in efuse.
Tuya BK7231N seems to be using always the following key: 510fb093 a3cbeadc 5993a17e c7adeb03.
There are, however, also some BK7231M or BL2028N devices that are using other key, namely: 00000000 00000000 00000000 00000000. Note that not all BL2028N are using the "all zero" keys, only some of them.
In their case, for the firmware to work, you must flash a proper version (compiled with correct key).
You can do it easily with out flasher (version 1.3 or later):
https://github.com/openshwprojects/BK7231GUIFlashTool
To know your key, just run Do firmware backup (read) only. In older versions, it will just print the key:
In new versions, if you are using BK7231N mode and key is not as expected, it will show error:
So, the solution is simple - but just remember to make 2MB backup first!.
Just set the BK7231M role:
Then get latest build from web:
And then, finally, flash it to your BK7231M/similiar in BK7231M mode.
The flasher is configured in such a way that even for QIO, it will leave old M-style bootloader, and only append OBK to it.
Now you can also do two more things:
- do restore RF (if your MAC ends with 00 00 , and most likely it will):
- configure your WiFi without using AP mode, in the flasher (this is also optional):
It should flash correctly, and OBK should boot:

Even in AP mode, you should be able to access your device and configure it:
Once you configure it, it should connect to your WiFi easily.
And that's all! That's how you can run your BK7231M modules with OBK.
Now, here is some miscelaneous information:
- BK7231 Easy UART flasher used to overwrite bootloader for N platform, but this is no longer the case - it detects QIO file and skips the bootloader section. You can still change this behaviour in advanced options
- here is a TX2 boot log from BK7231M:

If you see a similiar bootlog before flashing, it may be BK7231M
- CB2S with BK7231M was send to me by a reader and it was in LSPA9 clone marked as BSD33
- if you have overwritten your bootloader before (for example, with old flasher, that flashed QIO without skipping bootloader), you may need to restore the original bootloader for your chip to work
That's all for now, let me know if the new binary type works for you! I'm available and ready to fix potential issues, just let me know.
Cool? Ranking DIY Helpful post? Buy me a coffee.
