由于 MIX 2S 的 System 分区过小,导致部分 gsi 无法刷入,故扩容分区,顺便制作为卡刷包方便使用。
i:确保您的设备为小米 MIX 2s
ii:设备已解除BL锁并拥有第三方 Recovery
i:下载本人提供的 MIX2s_5GB_System.zip 文件
ii:重启至 Recovery
iii:找到 MIX2s_5GB_System.zip 并刷入
iv:重启至 Recovery,格式化: System,Vendor,Data
注意:由于会清除 System,Vendor,Data 三个分区的数据,请提前备份您的所有重要数据,如果您的身边没有电脑或其它存储设备,请下载 los 的 ROM 并复制到 /cust 目录一份,方便刷入。
使用 sgdisk
对磁盘进行重新分区
Q:扩容之后可以还原吗?
A:可以,刷一次 3GB 的文件即可还原。另:如果已经扩容分区,之后想更换其它的大小的分区,请务必先还原。
Q:扩容之后可以刷官方 ROM 吗?
A:可以,但是需要注意官方有 dm 校验,不去除会卡第一屏,可以通过同时刷入 magisk 去除。
Q:扩容之后可以线刷吗?
A:可以,但不推荐这样做,如果需要线刷,请勿勾选锁定选项,否则可能会导致需要售后解决。
Q:为什么我扩容之后刷入 ROM 却显示 System 大小为 3GB
A:这是因为 ROM 打包时是按照 3GB 大小打包的,请前往 Recovery,点击:分区管理 - System - 调整分区大小。Vendor 分区同理。
此方法极度危险,并且不推荐使用,如果您没有相关经验,请谨慎。
手机重启至第三方 Recovery 连接电脑,下载我提供的无损扩容文件
