Roborock s50 region lock error!

Hello, I am new in hassio and I have a doubt with the roborock s50. I have the European version of roborock but I remove the regional block to use it in china. The problem is that in Hassio I have it linked but sometimes it doesn’t connect me, it throws me an error - 10002 and tells me that roborock is inaccessible. When I enter my home and click on the roborock when it is loaded in my home, it is loaded in hassio. Any solution?

You can either try to fake Chinese region, see https://www.hardreset.info/devices/xiaomi/xiaomi-mijia-roborock-s50/change-region/ but in my case it noticed after a day or so, or you can root the robot and modify the firmware to change it to international.
The latter is more involved and with an actual risk of bricking the robot so I’ll let to you how to do it and to read about the risks.
