How to update images?

There are three ways to update images：

(The corresponding tools are in the RKTools/ directory of the source code)

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 Android system.

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

        Android12.0 upgrade to Android12.0.

（3）Using update.zip to upgrade.

        update.zip comes from the rockdev\image in the publishing system image package and is renamed from PRODUCT-NAME-ota-XX.zip

3._Using_bootup_sd_disk made_by SDDiskTool.

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

          Android12.0 upgrade to Android12.0.

（2）Using update.img to upgrade.
