小米、Redmi 与 POCO 技术支持

Xiaomi/HyperOS enforces a Mi Unlock waiting period (7 days minimum, sometimes 30+ days for new accounts) tied to your Mi Account age and login history. We can sometimes shorten this with account-aging tricks but cannot fully eliminate it on current HyperOS versions. We always tell you the realistic wait based on your specific account before starting.

Yes — Mi Account lock (also called Mi Cloud lock) typically triggers when a previous owner reported the device as lost or you failed too many sign-in attempts. We remove Mi Cloud lock on most Redmi and POCO models via test-point or EDL methods. We do verify ownership (IMEI check + purchase proof) before starting because we will not service stolen devices.

需核对机型差异、地区签名、防回滚和 BL 状态。有些转换不可行，有些会清除数据或影响网络；不能先刷再看。

Root 不等于换系统，但 OTA、支付、银行、设备认证和厂商安全应用可能改变。逐项测试你真正使用的应用，不承诺“所有功能原样保留”。

Mostly no. Magisk root on Xiaomi keeps MIUI/HyperOS, Mi Cloud, theme store and most system apps working. Banking apps and Google Wallet require Play Integrity bypass (we install Shamiko + DenyList). The only feature that breaks consistently is Mi Pay in China, and on HyperOS some "secure" apps (Banking SDK v3) need additional patches we apply during setup.
