安卓设备恢复方法（仅限手机和带有音量键的平板）：
第一步：关机；
第二步：同时按住开机键（电源键）+音量键上键十秒左右，进入recovery模式；
第三步：清除设备内存数据和缓存（双清），分别点击两个“wipe”选项，进入并选择“yes
”，确认清除文件；
第四步：选择“apply update from sdcard”选项，选择下载的刷机包即可进行刷机；
第五步：待刷机完成以后。即可选择“reboot system now”进行及其重启。
安卓设备刷机及恢复注意事项：
1.刷机或恢复之前保持手机电量在60%左右，防止设备电池供电不足导致“变砖”。
2.刷机或恢复之前注意备份重要文件，以防丢失。
3.刷机文件最好放在SD卡，刷机是选择“apply update from SDcard”。
4.刷机或恢复成功后第一次开机时间较长，请勿随意操作设备，待设备初始化完成方可正常使
用。

下载刷机大师，上面有指南，一键刷机，上面有平板电脑的系统，下载下来一键就可以安装需要繁琐操作。
国产平板电脑的刷机方法跟手机是不同的！很多刷机软件是不支持平板的！
1、获取官方固件或第三方固件
2、下载厂家的刷机工具或第三方刷机软件 如：平板刷机王
3、刷机操作，分手刷和机刷，还是建议同平板刷机王一键刷机吧！
官方的刷机方法太麻烦了，需要安装一系列的驱动和软件，我现在刷机就用平板刷机王，百度搜
索一下，有下载的
