备份

1、制作备份脚本if [ ! $1 ];thenl衡痕贤伎s -l /dev/block/platform/msm_sdcc.1/by-name/ 匀舶热圾| awk '{print "cat "$8">/sdcard/"$6".img"}'>/sdcard/bak_catls -l /dev/block/platform/msm_sdcc.1/by-name/ | awk '{print "dd if="$8 " of=/sdcard/"$6".img bs=512" }'>/sdcard/bak_ddelseif [ $1 = "f" ];thenecho "fastboot oem unlock">/sdcard/restore_fastbootls -l /dev/block/platform/msm_sdcc.1/by-name/ | awk '{print "fastboot erase " $6}'>> /sdcard/restore_fastbootecho " ############">>/sdcard/restore_fastbootls -l /dev/block/platform/msm_sdcc.1/by-name/ | awk '{print "fastboot flash " $6 " " $6 ".img" }'>>/sdcard/restore_fastbootelsels -l /dev/block/platform/msm_sdcc.1/by-name/ | awk '{print "dd if=/sdcard/"$6".img" " of="$8}'>/sdcard/restore_ddfi################################################/system/bin/fenqu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 ffastboot还原 /sdcard/restore_fastboot################################################/system/bin/fenqu xdd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.imgcat /dev/block/mmcblk0p8>/sdcard/boot.imgcat /dev/block/mmcblk0p9>/sdcard/boot1.imgcat /dev/block/mmcblk0p19>/sdcard/cache.imgcat /dev/block/mmcblk0p11>/sdcard/misc.imgcat /dev/block/mmcblk0p1>/sdcard/modem.imgcat /dev/block/mmcblk0p12>/sdcard/modem_st1.imgcat /dev/block/mmcblk0p13>/sdcard/modem_st2.imgcat /dev/block/mmcblk0p18>/sdcard/persist.imgcat /dev/block/mmcblk0p17>/sdcard/recovery.imgcat /dev/block/mmcblk0p5>/sdcard/rpm.imgcat /dev/block/mmcblk0p2>/sdcard/sbl1.imgcat /dev/block/mmcblk0p3>/sdcard/sbl2.imgcat /dev/block/mmcblk0p6>/sdcard/sbl3.imgcat /dev/block/mmcblk0p15>/sdcard/system.imgcat /dev/block/mmcblk0p16>/sdcard/system1.imgcat /dev/block/mmcblk0p10>/sdcard/tz.imgcat /dev/block/mmcblk0p20>/sdcard/userdata.img

3、dd if屏顿幂垂=/dev/block/mmcblk0p7 of=/sdcard/aboot.img bs=512dd if=/d髫潋啜缅ev/block/mmcblk0p8 of=/sdcard/boot.img bs=512dd if=/dev/block/mmcblk0p9 of=/sdcard/boot1.img bs=512dd if=/dev/block/mmcblk0p19 of=/sdcard/cache.img bs=512dd if=/dev/block/mmcblk0p11 of=/sdcard/misc.img bs=512dd if=/dev/block/mmcblk0p1 of=/sdcard/modem.img bs=512dd if=/dev/block/mmcblk0p12 of=/sdcard/modem_st1.img bs=512dd if=/dev/block/mmcblk0p13 of=/sdcard/modem_st2.img bs=512dd if=/dev/block/mmcblk0p18 of=/sdcard/persist.img bs=512dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img bs=512dd if=/dev/block/mmcblk0p5 of=/sdcard/rpm.img bs=512dd if=/dev/block/mmcblk0p2 of=/sdcard/sbl1.img bs=512dd if=/dev/block/mmcblk0p3 of=/sdcard/sbl2.img bs=512dd if=/dev/block/mmcblk0p6 of=/sdcard/sbl3.img bs=512dd if=/dev/block/mmcblk0p15 of=/sdcard/system.img bs=512dd if=/dev/block/mmcblk0p16 of=/sdcard/system1.img bs=512dd if=/dev/block/mmcblk0p10 of=/sdcard/tz.img bs=512dd if=/dev/block/mmcblk0p20 of=/sdcard/userdata.img bs=512

还原

1、dd if屏顿幂垂=/sdcard/aboot.img of=/dev/block/mmcblk0p7dd if=/sdcard/b泠贾高框oot.img of=/dev/block/mmcblk0p8dd if=/sdcard/boot1.img of=/dev/block/mmcblk0p9dd if=/sdcard/cache.img of=/dev/block/mmcblk0p19dd if=/sdcard/misc.img of=/dev/block/mmcblk0p11dd if=/sdcard/modem.img of=/dev/block/mmcblk0p1dd if=/sdcard/modem_st1.img of=/dev/block/mmcblk0p12dd if=/sdcard/modem_st2.img of=/dev/block/mmcblk0p13dd if=/sdcard/persist.img of=/dev/block/mmcblk0p18dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17dd if=/sdcard/rpm.img of=/dev/block/mmcblk0p5dd if=/sdcard/sbl1.img of=/dev/block/mmcblk0p2dd if=/sdcard/sbl2.img of=/dev/block/mmcblk0p3dd if=/sdcard/sbl3.img of=/dev/block/mmcblk0p6dd if=/sdcard/system.img of=/dev/block/mmcblk0p15dd if=/sdcard/system1.img of=/dev/block/mmcblk0p16dd if=/sdcard/tz.img of=/dev/block/mmcblk0p10dd 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-bootloaderfastboot oem unlockfastboot erase abootfastboot erase bootfastboot erase boot1fastboot erase cachefastboot erase miscfastboot erase modemfastboot erase modem_st1fastboot erase modem_st2fastboot erase persistfastboot erase recoveryfastboot erase rpmfastboot erase sbl1fastboot erase sbl2fastboot erase sbl3fastboot erase systemfastboot erase system1fastboot erase tzfastboot erase userdata

3、手机用数据线连接电脑adb reboot-bootloader‍fastboot flash aboot aboot.imgfastboot flash boot boot.imgfastboot flash boot1 boot1.imgfastboot flash cache cache.imgfastboot flash misc misc.imgfastboot flash modem modem.imgfastboot flash modem_st1 modem_st1.imgfastboot flash modem_st2 modem_st2.imgfastboot flash persist persist.imgfastboot flash recovery recovery.imgfastboot flash rpm rpm.imgfastboot flash sbl1 sbl1.imgfastboot flash sbl2 sbl2.imgfastboot flash sbl3 sbl3.imgfastboot flash system system.imgfastboot flash system1 system1.imgfastboot flash tz tz.imgfastboot 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
