How to update images?

There are three ways to update images：

1._Using_AndroidToool.

There is no limitation by this way.

2._Using_storage（such sd_or_USB_disk）with_update.zip_in_it.

There are some limitations：

（1）The device must be able to boot up to Debian.

（2）Only update images from the same os,  eg : 

        Debian upgrade to Debian.

（3）Using update.img to upgrade. 

3._Using_bootup_sd_disk made_by SDDiskTool.

（1）Only update images from the same os,  eg : 

         Debian upgrade to Debian.

（2）Using update.img to upgrade.
