[Update #1] Author here: I made some further progress.

1. Like a few comments mentioned here, the remote event happens for multiple reasons. Especially triggered by their app when you start or stop cleaning etc. I missed mentioning it in the article. The one I showed was suspicious as the device got bricked just after that event.

2. I fixed it by reseting the firmware and it worked for 2 days now without any issues. After second day cleaning it went back to charge as usual and never turned on. The bricking happened again this time, and I see a similar remote event again. This time am 100% sure there was no action from my side on the App or remote control.

3. What I found so far, after cleaning completes, the device uploads the map (in PNG) and some more data (in binary) to their server (There are very clear logs for this). After this upload, it receives a remote event and stops working.

4. How did I fix the device? I've the backup of all files in the device. Rebooting the device after replacing the files do the trick.

5. Now it reports the device is not on flat surface. Probably a loose connection with sensors which am yet to figure out. This time I suspect the bricking technique has changed, we shall be updating after more research

Note: I am not sure if I can publicly share all techniques used to get access to the device. But it is very straightforward as mentioned in the article and very easy if you have some knowledge on adb (Android Debug Bridge) tools and a USB to micro usb wire.
