Some might work even with other brand devices, but this tool is not designed to do that, so please use it with Xiaomi devices. Some functionalities might be compatible with other Xiaomi devices (Android one ones for example, or Blackshark). It works best with MIUI devices (smartphones, tablets, Xiaomi, Pocophone, Redmi). If you are expert and you feel more comfortable not using it, go ahead, but for not expert user I would suggest to use XiaoMiTool as it’s probably safer than the average user trying on his own. I’m not responsible anyway of any of the possible outcomes of the usage of this tool
The chance of getting your device bricked is very little. It’s hard to guarantee “100% safeness” with this kind of operations, but I designed it to be the most safe as I can get.
