How to backup and restore android system on a Rockchip device?

Preparation

  • Rockchip Driver Assistant (I downloaded v4.3 from AndroidMTK.com as the latest version is not compatible with rkDumper) — driver for the rockchip fastboot mode
  • rkDumper (v1.0.8) — System backup tool
  • RKDevTool(v2.71) — System restore tool

Procedures

  • Extract Rockchip DriverAssistant
  • Go to the extracted folder and select DriverInstall, then follow the on-screen instruction
  • Make sure your Android device adb mode is enabled. You may want to read this article to enable adb mode on your Android device and install adb driver

  • Extract rkDumper
