+If there wasn't errors, then you backed up such partitions:
+```
+[root@WCV3:~]# cat /proc/mtd 
+dev:    size   erasesize  name
+mtd0: 00040000 00008000 "boot"
+mtd1: 001f0000 00008000 "kernel"
+mtd2: 003d0000 00008000 "rootfs"
+mtd3: 003d0000 00008000 "app"
+mtd4: 001f0000 00008000 "kback"

+mtd6: 00060000 00008000 "cfg"
+mtd7: 00010000 00008000 "para"
+```
+Save and keep this files in safe place.
+In case of any errors you should perform this operation once again, probably with microSD card replacement.
