方法一：输入查看分区cat /proc/mtd显示的内容----------------------------------------------------mtd0: 08000000 00020000 "spi0.1"mtd1: 00100000 00020000 "BL2"mtd2: 00040000 00020000 "Nvram"mtd3: 00040000 00020000 "Bdata"mtd4: 00200000 00020000 "Factory"mtd5: 00200000 00020000 "FIP"mtd6: 00040000 00020000 "crash"mtd7: 00040000 00020000 "crash_log"mtd8: 01e00000 00020000 "ubi"mtd9: 01e00000 00020000 "ubi1"mtd10: 03200000 00020000 "overlay"----------------------------------------------------找到FIP分区，并且备份FIP分区dd if=/dev/mtd5 of=/tmp/FIP.bin备份后要恢复官方FIP上传备份的FIP分区文件到tmp目录下登录SSH执行mtd write /tmp/备份的fip.bin /dev/mtd5拔电，官方救砖就行了
