强迫症非要合并boot，boot1，于是删掉了8-20分区，重新分区，然后重启变黑砖，fastboot和recovery不能用了，任何按键没有任何反应。小米1s15分区是system分区，重新分区是指分15-20分区这6个分区，15之前的不能动！分区之前必须备份分区！！12，13分区是基带，官方线刷包是不带这两个分区的，如果没有备份，即使刷回去了，手机一样会丢失IME串号等东西，没信号，永远飞行模式了救砖方法工具/原料moremiflash官方线刷包twrp recovery备份+还原方法1/4分步阅读

dd还原很傻，会按原分区1：1还原，所以会吞掉多出来的空间，到时候还得调整

所以建议system和data分区用recovery自带的打包备份还原工具

这样还原的时候不用管分区大小，fdisk分多少是多少

不用重新调整system+data分区

4/4

还可以把镜像文件拷到电脑，用fastboot还原

fastboot flash aboot aboot.img

fastboot flash boot boot.img

fastboot flash boot1 boot1.img

fastboot flash cache cache.img

fastboot flash misc misc.img

fastboot flash modem modem.img

miflash刷MIUI官方包1/2

下载安装miflash，miflash自带高通驱动

usb线连接手机到电脑

变砖之前我的电池是充满电的，连电脑也没有按任何按键

电脑是XP操作系统，所以usb连上就显示了找到QHSUSB_DLOAD，选择miflash的高通驱动的文件夹，安装驱动。

如果是win8，win10要F8重启禁止驱动签名

2/2

下载，解压线刷包，用miflash线刷

miflash刷新一下，找到手机，然后打开线刷包的解包位置，刷机，很快就好了

fastboot刷第三方recoverey1/1

重启，这时候就恢复了miui，进recovery双清后可以进MIUI，但是我是要刷CM11的，就不进去了

进fastboot

fastboot flash recovery TWRP.....img

之所以刷这个recovery而不用MIUI自带的是因为TWRP recovery自带busybox，而busybox可以用fdisk分区。

进recovery，fdisk重新分区1/2

因为线刷完分区就变成出厂默认的20个分区，所以前面1-14分区不管，只需要删除15-20分区，重新分。

改之前

重新分区之后，删掉system1，

system我分了600M

recovery20M

persist 10m不变

cache100m

剩下的3G给data

如果不能进recovery

可以把存储卡用读卡器读出来，镜像拷到电脑

重启进fastboot还原

fastboot flash modem_st1 modem_st1.img

fastboot flash modem_st2 modem_st2.img

fastboot flash system system.img

fastboot flash persist persist.img

fastboot flash recovery recovery.img

fastboot flash userdata userdata.img

重新调整分区大小1/3

dd还原比较傻，原镜像是多大，它就还原成多大，多余的空间被吞了，重新调整一下大小

e2fsck -f /dev/block/mmcblk0

resize2fs /dev/block/mmcblk0

2/3

如果是用recovery自带的打包备份，直接恢复system和data分区就可以了

不用重新调整

3/3

如果没有system和data镜像可以不用刷这两个分区，

直接把卡刷包放sd卡，进recovery重新刷机就行了
