使获取ROOT权限的设备在进行OTA升级时保持ROOT权限不会被取消，也可以对ROOT权限进行备份，安装需要已经获取ROOT权限支持。



要求：系统采用Ext2、Ext3、Ext4分区支持，并且OTA升级不会格式化系统分区。



目前已经支持多款设备，包括Nexus S、Galaxy Nexus、蜂窝平板等，明确不支持的设备包括HTC Desire、三星Galaxy S、Galaxy S Ⅱ等。

新版变化

Due to changes in 4.3 security implementations, OTA RootKeeper cannot work to 4.3 updates.

Root implementations (su and Superuser apks) have to be largely reworked.

This project is not abandonned, I'll see what I can do but please keep in mind I don't have a solution right now.
