How to&nbsp;update images?

There are three ways to update images：

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

=== '''[[Using_AndroidToool_for_NEW|1._Using_AndroidToool.]]''' ===

There is no limitation by this way.

=== '''[[2._Using_storage（such_sd_or_USB_disk）with_update.zip_in_it.|2._Using_storage（such&nbsp;sd_or_USB_disk）with_update.zip_in_it.]]''' ===

There are some&nbsp;limitations：

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

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

&nbsp; &nbsp; &nbsp; &nbsp; Android13.0 upgrade to Android13.0.

（3）Using update.zip to upgrade.

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

=== '''[[Using_bootup_sd_disk_made_by_SDDiskTool_for_new|3._Using_bootup_sd_disk&nbsp;made_by&nbsp;SDDiskTool.]]''' ===

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

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Android13.0 upgrade to Android13.0.

（2）Using update.img to upgrade.
