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 :
Android6.0 upgrade to Android6.0 or Android7.1 upgrade to Android7.1.
(3)Using update.zip to upgrade. (see more detail in "Create OTA zip" on how to create update.zip)
3._Using_bootup_sd_disk made_by SDDiskTool.
(1)Only update images from the same os, eg :
Android6.0 upgrade to Android6.0 or Android7.1 upgrade to Android7.1.
(2)Using update.img to upgrade.
