本文目录导读：
小米新系统自推出以来,凭借其流畅的操作体验和丰富的功能，赢得了众多用户的喜爱，有时候我们可能会因为某些原因需要删除或重置小米新系统，本文将为你详细介绍如何删除小米新系统，让你轻松搞定这一操作。
准备工作
在开始删除之前,请确保你已经备份了重要数据，以防意外丢失，你还需要了解以下注意事项：
-
确保设备电量充足：在删除系统前，请确保你的手机电量充足，以免因电量不足导致删除过程中手机关机。
-
了解系统版本：不同的小米手机型号可能使用不同的系统版本，因此请根据你的手机型号选择相应的删除方法。
-
备份重要数据：在删除系统前，请务必备份手机中的重要数据，以免误删导致数据丢失。
删除小米新系统的步骤
以下是删除小米新系统的详细步骤：
进入Fastboot模式
-
关闭手机,确保手机处于关机状态。
-
同时按住电源键和音量减小键（或电源键和菜单键），直到手机屏幕上出现小米Logo或相关提示。
-
松开按键,等待手机进入Fastboot模式，手机会显示一个FASTBOOT菜单。
刷入第三方Recovery
-
使用USB数据线将手机连接到电脑。
-
打开电脑上的终端或命令提示符窗口。
-
输入以下命令以获取Recovery镜像文件（以MIUI12为例）：
wget https://miui.securecdn.cn/download/recovery/miui12.0.13.0_r01_c16979957b4a.zip -
解压下载的ZIP文件,得到Recovery镜像文件（如miui12.0.13.0_r01_c16979957b4a.zip）。
-
使用ADB命令将Recovery镜像刷入手机：
adb reboot recovery adb install /path/to/miui12.0.13.0_r01_c16979957b4a.zip请将
/path/to/替换为实际的文件路径。
步骤三：删除系统
-
在Recovery模式下,使用ADB命令进入MIUI系统目录：
adb shell sm list packages -
在输出的列表中找到名为“system”的包名，然后使用ADB命令删除该系统包：
adb shell pm remove com.miui.securitycenter adb shell pm remove com.miui.home adb shell pm remove com.miui.searchbox adb shell pm remove com.miui.lockscreen adb shell pm remove com.miui.systemcenter

知识扩展阅读
为什么需要删除小米新系统？ （插入案例）朋友张先生上周刚升级到小米13 Ultra的全新MIUI 14系统，结果发现相机卡顿、耗电飙升，后悔升级才三天就想要回旧系统，这其实是很多用户升级后遇到的典型问题，根据2023年Q2小米系统问题报告显示，有18.6%的用户在更新后出现性能下降，尤其是影像处理类设备。
常见原因分析：
- 系统适配未完成：新系统可能缺少设备特有优化
- 硬件性能不足：中低端机型处理新系统吃力
- 用户习惯冲突：个性化设置导致异常（参考小米论坛热帖#）
- 软硬件兼容问题（如5G模块异常）
删除前的必要准备（表格对比） | 检查项目 | 必备内容 | 注意事项 | |-----------------|--------------------------|--------------------------| | 数据备份 | 手机数据+云相册 | 确认存储空间≥15GB | | 设备型号 | 全称确认（如小米12S Pro） | 避免混入Civi/数字系列 | | 系统版本 | 完整版本号（v184.0.12） | 检查更新日志 | | 充电状态 | 保持50%以上 | 避免断电导致操作失败 | | 网络环境 | 移动数据/WiFi | 关闭自动更新 |
（问答补充） Q：必须删除最新版本才能恢复旧系统吗？ A：不是！通过"设置-系统更新"中的"回退"功能，可保留部分新功能，但需注意：①需保留至少2GB可用空间 ②需在升级后7天内操作
Q：不同机型操作流程有差异吗？ A：是的！以小米数字系列为例：
- 12/13系列：设置-系统更新-恢复
- 11系列：设置-关于手机-重置
- Civi系列：设置-账户安全-设备重置（需密码）
删除操作全流程（分机型演示） 【以小米12S Pro为例】
- 完成系统更新至最新版本（v184.0.12）
- 进入安全模式：
- 同时按住电源键+音量-键3秒
- 选择"安全模式"
- 恢复旧系统：
- 设置-系统更新-右上角三横线
- 选择"系统回退"
- 确认要回退到v183.0.9版本
- 重启手机等待10分钟
（插入操作截图示意）
注意事项与风险提示
- 数据安全：
- 系统回退会自动恢复备份数据
- 但第三方应用需重新下载（如微信）
- 系统兼容性： | 风险等级 | 可能问题 | 解决方案 | |----------|--------------------------|------------------------| | 高 | 系统服务异常 | 重启或刷机 | | 中 | 部分应用闪退 | 卸载重装 | | 低 | 界面显示延迟 | 等待版本更新 |
（真实案例）用户李女士在回退MIUI 13后，发现微信无法扫码支付，经检查发现是支付模块未兼容，通过"设置-应用管理-微信-强制停止"后恢复正常。
删除后的优化建议
- 性能提升：
- 启用"性能模式"（设置-电池-性能模式）
- 关闭后台应用自启动（设置-应用管理-权限管理）
- 系统精简：
