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到电脑，用fastboot还原fastboot flash aboot aboot.imgfastboot fl锾攒揉敫ash 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
