【转】红米root方法，内置SD卡与外置SD卡置换方法。

1，下载百度一键ROOT，获取root权限
2，下载RE管理器，进入root fold的etc文件夹，找到vold.fstab文件，长按弹出菜单，选最后一项文件编制器（Open in Text Editor)
3，找到如下语句
dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
改成
dev_mount sdcard /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
其实就是上面红色数字互换
4，改好保存，推出重启，搞定！ 转自某论坛。
