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

备份+还原方法
1、备份ddif=/dev/block/mmcblk0p1of=/sdcard/水瑞侮瑜backups/p1.足毂忍珩imgddif=/dev/block/mmcblk0p2of=/sdcard/backups/p2.imgddif=/dev/block/mmcblk0p3of=/sdcard/backups/p3.imgddif=/dev/block/mmcblk0p4of=/sdcard/backups/p4.imgddif=/dev/block/mmcblk0p5of=/sdcard/backups/p5.imgddif=/dev/block/mmcblk0p6of=/sdcard/backups/p6.imgddif=/dev/block/mmcblk0p7of=/sdcard/backups/p7.imgddif=/dev/block/mmcblk0p8of=/sdcard/backups/p8.imgddif=/dev/block/mmcblk0p9of=/sdcard/backups/p9.imgddif=/dev/block/mmcblk0p10of=/sdcard/backups/p10.imgddif=/dev/block/mmcblk0p11of=/sdcard/backups/p11.imgddif=/dev/block/mmcblk0p12of=/sdcard/backups/p12.imgddif=/dev/block/mmcblk0p13of=/sdcard/backups/p13.imgddif=/dev/block/mmcblk0p14of=/sdcard/backups/p14.imgddif=/dev/block/mmcblk0p15of=/sdcard/backups/p15.imgddif=/dev/block/mmcblk0p16of=/sdcard/backups/p16.imgddif=/dev/block/mmcblk0p17of=/sdcard/backups/p17.imgddif=/dev/block/mmcblk0p18of=/sdcard/backups/p18.imgddif=/dev/block/mmcblk0p19of=/sdcard/backups/p19.imgddif=/dev/block/mmcblk0p20of=/sdcard/backups/p20.img还原ddif=/sdcard/backups/p1.imgof=/dev/block/mmcblk0p1ddif=/sdcard/backups/p2.imgof=/dev/block/mmcblk0p2ddif=/sdcard/backups/p3.imgof=/dev/block/mmcblk0p3ddif=/sdcard/backups/p4.imgof=/dev/block/mmcblk0p4ddif=/sdcard/backups/p5.imgof=/dev/block/mmcblk0p5ddif=/sdcard/backups/p6.imgof=/dev/block/mmcblk0p6ddif=/sdcard/backups/p7.imgof=/dev/block/mmcblk0p7ddif=/sdcard/backups/p8.imgof=/dev/block/mmcblk0p8ddif=/sdcard/backups/p9.imgof=/dev/block/mmcblk0p9ddif=/sdcard/backups/p10.imgof=/dev/block/mmcblk0p10ddif=/sdcard/backups/p11.imgof=/dev/block/mmcblk0p11ddif=/sdcard/backups/p12.imgof=/dev/block/mmcblk0p12ddif=/sdcard/backups/p13.imgof=/dev/block/mmcblk0p13ddif=/sdcard/backups/p14.imgof=/dev/block/mmcblk0p14ddif=/sdcard/backups/p15.imgof=/dev/block/mmcblk0p15ddif=/sdcard/backups/p16.imgof=/dev/block/mmcblk0p16ddif=/sdcard/backups/p17.imgof=/dev/block/mmcblk0p17ddif=/sdcard/backups/p18.imgof=/dev/block/mmcblk0p18ddif=/sdcard/backups/p19.imgof=/dev/block/mmcblk0p19ddif=/sdcard/backups/p20.imgof=/dev/block/mmcblk0p20
2、或者备份mkd坡纠课柩ir/sdcard/backups/ddif=/dev/block/mmcblk0p1of=/s颊俄岿髭dcard/backups/modem.imgddif=/dev/block/mmcblk0p2of=/sdcard/backups/sbl1.imgddif=/dev/block/mmcblk0p3of=/sdcard/backups/sbl2.imgddif=/dev/block/mmcblk0p5of=/sdcard/backups/rpm.imgddif=/dev/block/mmcblk0p6of=/sdcard/backups/sbl3.imgddif=/dev/block/mmcblk0p7of=/sdcard/backups/aboot.imgddif=/dev/block/mmcblk0p8of=/sdcard/backups/boot.imgddif=/dev/block/mmcblk0p9of=/sdcard/backups/boot1.imgddif=/dev/block/mmcblk0p10of=/sdcard/backups/tz.imgddif=/dev/block/mmcblk0p11of=/sdcard/backups/misc.imgddif=/dev/block/mmcblk0p12of=/sdcard/backups/modem_st1.imgddif=/dev/block/mmcblk0p13of=/sdcard/backups/modem_st2.imgddif=/dev/block/mmcblk0p15of=/sdcard/backups/system.imgddif=/dev/block/mmcblk0p16of=/sdcard/backups/system1.imgddif=/dev/block/mmcblk0p17of=/sdcard/backups/recovery.imgddif=/dev/block/mmcblk0p18of=/sdcard/backups/persist.imgddif=/dev/block/mmcblk0p19of=/sdcard/backups/cache.imgddif=/dev/block/mmcblk0p20of=/sdcard/backups/userdata.img还原ddif=/sdcard/backups/modem.imgof=/dev/block/mmcblk0p1ddif=/sdcard/backups/sbl1.imgof=/dev/block/mmcblk0p2ddif=/sdcard/backups/sbl2.imgof=/dev/block/mmcblk0p3ddif=/sdcard/backups/rpm.imgof=/dev/block/mmcblk0p5ddif=/sdcard/backups/sbl3.imgof=/dev/block/mmcblk0p6ddif=/sdcard/backups/aboot.imgof=/dev/block/mmcblk0p7ddif=/sdcard/backups/boot.imgof=/dev/block/mmcblk0p8ddif=/sdcard/backups/boot1.imgof=/dev/block/mmcblk0p9ddif=/sdcard/backups/tz.imgof=/dev/block/mmcblk0p10ddif=/sdcard/backups/misc.imgof=/dev/block/mmcblk0p11ddif=/sdcard/backups/modem_st1.imgof=/dev/block/mmcblk0p12ddif=/sdcard/backups/modem_st2.imgof=/dev/block/mmcblk0p13ddif=/sdcard/backups/system.imgof=/dev/block/mmcblk0p15ddif=/sdcard/backups/system1.imgof=/dev/block/mmcblk0p16ddif=/sdcard/backups/recovery.imgof=/dev/block/mmcblk0p17ddif=/sdcard/backups/persist.imgof=/dev/block/mmcblk0p18ddif=/sdcard/backups/cache.imgof=/dev/block/mmcblk0p19ddif=/sdcard/backups/userdata.imgof=/dev/block/mmcblk0p20
3、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、还可以把镜像文件拷咦筋庑檗到电脑，用fastboot还原fastbootflashabootaboot.imgfastbootfl锾攒揉敫ashbootboot.imgfastbootflashboot1boot1.imgfastbootflashcachecache.imgfastbootflashmiscmisc.imgfastbootflashmodemmodem.imgfastbootflashmodem_st1modem_st1.imgfastbootflashmodem_st2modem_st2.imgfastbootflashpersistpersist.imgfastbootflashrecoveryrecovery.imgfastbootflashrpmrpm.imgfastbootflashsbl1sbl1.imgfastbootflashsbl2sbl2.imgfastbootflashsbl3sbl3.imgfastbootflashsystemsystem.imgfastbootflashsystem1system1.imgfastbootflashtztz.imgfastbootflashuserdatauserdata.img
miflash刷MIUI官方包
1、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、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recoverey
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fastbootfastbootflashrecoveryTWRP.....img之所以刷这个recovery而不用MIUI自带的是因为TWRPrecovery自带busybox，而busybox可以用fdisk分区。
进recovery，fdisk重新分区
1、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600Mrecovery20Mpersist10m不变cache100m剩下的3G给data
2、分区脚本fdisk/dev/block/mmcblk0d20d19d18d17d16d15n2086694108n9411094111n9411396554n9655697777n97779109986n109988回车t1583t1683t1760t1883t1983t2083w
恢复分区
1、1-11分区线刷包自带了，刚刚线刷过，所以不用管刷回基带的12，13，和system，persist，recovery
2、ddif=/sdcard/backups/p12.imgof=/dev/block/mmcblk0p12ddif=/sdcard/backups/p13.imgof=/dev/block/mmcblk0p13ddif=/sdcard/backups/p15.imgof=/dev/block/mmcblk0p15ddif=/sdcard/backups/p17.imgof=/dev/block/mmcblk0p17ddif=/sdcard/backups/p18.imgof=/dev/block/mmcblk0p18ddif=/sdcard/backups/p20.imgof=/dev/block/mmcblk0p20
3、或者ddif屏顿幂垂=/sdcard/backups/modem_st1.imgof=/dev/block/mmcblk0p12颊俄岿髭ddif=/sdcard/backups/modem_st2.imgof=/dev/block/mmcblk0p13ddif=/sdcard/backups/system.imgof=/dev/block/mmcblk0p15ddif=/sdcard/backups/recovery.imgof=/dev/block/mmcblk0p17ddif=/sdcard/backups/persist.imgof=/dev/block/mmcblk0p18ddif=/sdcard/backups/userdata.imgof=/dev/block/mmcblk0p20
4、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fastbootflashmodem_st1modem_st1.imgfastbootflashmodem_st2modem_st2.imgfastbootflashsystemsystem.imgfastbootflashpersistpersist.imgfastbootflashrecoveryrecovery.imgfastbootflashuserdatauserdata.img
重新调整分区大小
1、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/mmcblk0resize2fs/dev/block/mmcblk0
2、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、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
