Arnova 7b G3 ICS custom firmware with Google Play, Apps and root

The Arnova 7b G3 is an entry level Android 4.0 ICS Ice Cream Sandwich tablet, featuring a Rockchip RK2918 CPU, 1 Gb of RAM, 7″ capacitive screen and front camera. We have built a custom firmware based on Arnova’s latest firmware release from the 12th of July, adding Google Play/Android Market and full root with read-write access to /system partition.


We would like to thank technoboi and SupArnova forum members for their help with the firmware tests.

Arnova 7b G3 custom firmware features

  • Clean installation of latest Google Play Store 3.5.15, no more missing apps (Twitter, Facebook…)
  • Full root support with writable /system partition
  • Root access is controled thru SuperSU.apk v0.89 (free version), a cool upgrade to SuperUser.apk by XDA developer Chainfire
  • Updated Rockchip loader to latest version (2.20)
  • Our custom firmware can be installed in two ways. The first method is the easiest and will let you have Google Play running in about 10 minutes. The second method erases all the data stored on the tablet, but uses a safer approach.

    Arnova 7b G3 custom firmware install easy procedure

    Please note that this flashing method is easy to run but includes the same risks as a regular firmware flash. If it goes wrong for some reason and bricks your tablet, the only way to recover it (if the hardware isn’t damaged) will be to use Rockchip Flashing tool.

    Please note this first firmware install method keeps installed apps and data on the tablet.

    Step 1. Download and install Arctools from Appslib.

    Run Appslib that can be found in the applications on your tablet. While in Appslib, search for “Arctools” application, you should get “ArcTools (Market Apps installer & Disk tester)” in the list, download, install and run the application.

    If you don’t have Appslib installed, you’ll need to download it from appslib.com servers.

    Step 2. Download firmware

    In Arctools, go to Firmware tab, select “Arnova 7b G3 (capacitive model) custom firmware 0.42 EZ” (or more recent than 0.4 if there is one)
    Read the disclaimer in the application and press the checkbox if you agree with the conditions, then press the Download button.
    It should take about two minutes to complete the new firmware download.
    Restart the tablet when the program is inviting you to.

    Step 3. Flashing the firmware
    After rebooting the tablet, a “Firmware updating” dialog will ask for confirmation to install the package (=flash the firmware) click Install button. The tablet will reboot and install the firmware.

    Step 4. Setup Google Play
    After a few minutes, your tablet will be updated with the custom firmware. Setup your Account on Google Play Store and enjoy !
