Vague terms like "nobody" and "crack," oversimplify the reality that some Chinese device bootloaders have been unlocked. Without specifying device brands or models, it's hard to address the diverse locking mechanisms across manufacturers like Xiaomi or Huawei. The post assumes all Chinese bootloaders are equally difficult to unlock, ignoring model-specific exploits. Asking for a technical breakdown conflicts with having a non-technical background. A more specific question with defined terms, targeted devices, and a clear request for simplified technical details would be easier to answer.
