安卓手机手动【备份+还原】分区

1、制作备份脚本

if [ ! $1 ];then

ls -l /dev/block/platform/msm_sdcc.1/by-name/  | awk '{print "cat "$8">/sdcard/"$6".img"}'>/sdcard/bak_cat

ls -l /dev/block/platform/msm_sdcc.1/by-name/  | awk '{print "dd if="$8 " of=/sdcard/"$6".img bs=512" }'>/sdcard/bak_dd

else

if [ $1 = "f" ];then

echo "fastboot oem unlock">/sdcard/restore_fastboot

ls -l /dev/block/platform/msm_sdcc.1/by-name/  | awk '{print "fastboot erase " $6}'>> /sdcard/restore_fastboot

echo " ############">>/sdcard/restore_fastboot

ls -l /dev/block/platform/msm_sdcc.1/by-name/  | awk '{print "fastboot flash " $6 " " $6 ".img" }'>>/sdcard/restore_fastboot

else

ls -l /dev/block/platform/msm_sdcc.1/by-name/  | awk '{print "dd if=/sdcard/"$6".img" " of="$8}'>/sdcard/restore_dd

fi

################################################

在sd卡上生成备份文件

/bak_cat

/bak_dd

分别使用dd和cat备份

################################################

/system/bin/fenqu f

fastboot还原       /sdcard/restore_fastboot

################################################

/system/bin/fenqu x

dd还原               /sdcard/restore_dd

################################################

随意打开一个，删掉cache.img所在的行

如果system和data不想要了，也可以删掉

2、‍cat /dev/block/mmcblk0p7>/sdcard/aboot.img

cat /dev/block/mmcblk0p8>/sdcard/boot.img

cat /dev/block/mmcblk0p9>/sdcard/boot1.img

cat /dev/block/mmcblk0p19>/sdcard/cache.img

cat /dev/block/mmcblk0p11>/sdcard/misc.img

cat /dev/block/mmcblk0p1>/sdcard/modem.img

cat /dev/block/mmcblk0p12>/sdcard/modem_st1.img

cat /dev/block/mmcblk0p13>/sdcard/modem_st2.img

cat /dev/block/mmcblk0p18>/sdcard/persist.img

cat /dev/block/mmcblk0p17>/sdcard/recovery.img

cat /dev/block/mmcblk0p5>/sdcard/rpm.img

cat /dev/block/mmcblk0p2>/sdcard/sbl1.img

cat /dev/block/mmcblk0p3>/sdcard/sbl2.img

cat /dev/block/mmcblk0p6>/sdcard/sbl3.img

cat /dev/block/mmcblk0p15>/sdcard/system.img

cat /dev/block/mmcblk0p16>/sdcard/system1.img

cat /dev/block/mmcblk0p10>/sdcard/tz.img

cat /dev/block/mmcblk0p20>/sdcard/userdata.img

3、dd if=/dev/block/mmcblk0p7 of=/sdcard/aboot.img bs=512

dd if=/dev/block/mmcblk0p8 of=/sdcard/boot.img bs=512

dd if=/dev/block/mmcblk0p9 of=/sdcard/boot1.img bs=512

dd if=/dev/block/mmcblk0p19 of=/sdcard/cache.img bs=512

dd if=/dev/block/mmcblk0p11 of=/sdcard/misc.img bs=512

dd if=/dev/block/mmcblk0p1 of=/sdcard/modem.img bs=512

dd if=/dev/block/mmcblk0p12 of=/sdcard/modem_st1.img bs=512

dd if=/dev/block/mmcblk0p13 of=/sdcard/modem_st2.img bs=512

dd if=/dev/block/mmcblk0p18 of=/sdcard/persist.img bs=512

dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img bs=512

dd if=/dev/block/mmcblk0p5 of=/sdcard/rpm.img bs=512

dd if=/dev/block/mmcblk0p2 of=/sdcard/sbl1.img bs=512

dd if=/dev/block/mmcblk0p3 of=/sdcard/sbl2.img bs=512

dd if=/dev/block/mmcblk0p6 of=/sdcard/sbl3.img bs=512

dd if=/dev/block/mmcblk0p15 of=/sdcard/system.img bs=512

dd if=/dev/block/mmcblk0p16 of=/sdcard/system1.img bs=512

dd if=/dev/block/mmcblk0p10 of=/sdcard/tz.img bs=512

dd if=/dev/block/mmcblk0p20 of=/sdcard/userdata.img bs=512

1、dd if=/sdcard/aboot.img of=/dev/block/mmcblk0p7

dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8

dd if=/sdcard/boot1.img of=/dev/block/mmcblk0p9

dd if=/sdcard/cache.img of=/dev/block/mmcblk0p19

dd if=/sdcard/misc.img of=/dev/block/mmcblk0p11

dd if=/sdcard/modem.img of=/dev/block/mmcblk0p1

dd if=/sdcard/modem_st1.img of=/dev/block/mmcblk0p12

dd if=/sdcard/modem_st2.img of=/dev/block/mmcblk0p13

dd if=/sdcard/persist.img of=/dev/block/mmcblk0p18

dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17

dd if=/sdcard/rpm.img of=/dev/block/mmcblk0p5

dd if=/sdcard/sbl1.img of=/dev/block/mmcblk0p2

dd if=/sdcard/sbl2.img of=/dev/block/mmcblk0p3

dd if=/sdcard/sbl3.img of=/dev/block/mmcblk0p6

dd if=/sdcard/system.img of=/dev/block/mmcblk0p15

dd if=/sdcard/system1.img of=/dev/block/mmcblk0p16

dd if=/sdcard/tz.img of=/dev/block/mmcblk0p10

dd if=/sdcard/userdata.img of=/dev/block/mmcblk0p20

2、如果哪个分区刷不进 ，可用fastboot先将它清空

手机用数据线连接电脑

adb reboot-bootloader

fastboot oem unlock

fastboot erase aboot

fastboot erase boot

fastboot erase boot1

fastboot erase cache

fastboot erase misc

fastboot erase modem

fastboot erase modem_st1

fastboot erase modem_st2

fastboot erase persist

fastboot erase recovery

fastboot erase rpm

fastboot erase sbl1

fastboot erase sbl2

fastboot erase sbl3

fastboot erase system

fastboot erase system1

fastboot erase tz

fastboot erase userdata

3、手机用数据线连接电脑

adb reboot-bootloader

‍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

fastboot flash modem_st1 modem_st1.img

fastboot flash modem_st2 modem_st2.img

fastboot flash persist persist.img

fastboot flash recovery recovery.img

fastboot flash rpm rpm.img

fastboot flash sbl1 sbl1.img

fastboot flash sbl2 sbl2.img

fastboot flash sbl3 sbl3.img

fastboot flash system system.img

fastboot flash system1 system1.img

fastboot flash tz tz.img

fastboot flash userdata userdata.img

4、一般刷机是刷recovery+system分区，/data /cache是随意格式化的。

小米system2是双系统用的，所以可删掉。将两个系统的大小合并到1个，sytem2分1个1兆的小分区意思一下就行了。

其他的不知道做什么别乱删了

要注意刷机包的大小要小于要刷的分区的大小，否则刷不进。

需要重新分区或者换缩小包
