Arnova 8c G3 is a nice looking Android 4.0 tablet with great features for an affordable price. It comes with Android 4.0.3 Ice Cream Sandwich, featuring a Rockchip RK2918 CPU, 1 GB of RAM and a 5-point multi-touch capacitive screen. In addition to our first custom firmware which brings root and Google Play on the device, we are now happy to provide a Jelly Bean custom firmware. Though we developed this firmware with the Arnova 8c G3 in mind, it should also work on BQ Kepler 2, Nextbook Premium 8SE and Prestigio 5080CPRO devices.

Main features:

  • Android 4.1.1 built from Oma JB v1.2.2
  • System in ext4 format
  • CWM Touch Recovery built from Prestigio 5080B
  • Custom kernel from JochenKauz (+optional overclocked kernel)
  • Up to 1.5GB for apps partition
  • Full google experience with Google+, Talk, Calendar and more
  • Google Ears&Now included
  • Picture in Picture (PIP) video player

This firmware also features full Google Play support and read/write access to /system partition.

Firmware limitations:

  • No USB debugging
  • Camera image mirrored

Arnova 8c G3 custom firmware install procedure

Before starting, please make sure you backup all your existing apps, data and files that are on your tablet as they will be erased during the flash process. Also make sure your device is connected to the power.

Step 1. Download

AN8CG3-20121109OMA4.1| ONLY FOR ARNOVA 8C G3 MODEL |

This firmware is specific to the Arnova 8C G3 model and should not be installed on other devices.
WE WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE. THIS FIRMWARE UPDATE IS USED AT YOUR OWN RISK.WE RECOMMEND TO FLASH THIS FIRMWARE ONLY IF YOU ARE ABLE TO RESCUE A BRICKED DEVICE USING ROCKCHIP FLASHING TOOLS.

Download the file from above and extract the custom firmware files on your computer hard drive.

Step 2. Installing the driver

Please follow the Rockchip Flashing tool procedure: that will explain how to download Rockchip flashing tool, put your device into flashing mode and install the driver. Because we are using a different setup here(otherwise we would have to build six different firmwares), you only need to follow steps 1-3 from that tutorial. Please note that this procedure won’t work on Windows 8.

Step 3. Installation

Run EvolutionRKTool program from the first archive. Check that your tablet is connected by usb and is put in the recovery mode. RKAndroidTool should say “Found RKAndroid Loader Rock Usb”. There are three parameter files in the Loader folder. Select one of the three, corresponding to the size of the Apps partition you want to have(parameter for 512MB, parameter-1G for 1GB and parameter-15G for 1.5GB). Now tick the other boxes as shown on the picture below. Please note that Loader and Backup boxes are not ticked. If you want to use the overclocked kernel, locate the kernel-oc file for the kernel.

Now, click on EraseIDB. After the proces is finished(should take around 15 seconds), click on Run. When the CWM Recovery will show up on the device, choose Reboot System now. After a couple of minutes, the Start-up Wizard should appear. Please note that the portrait wizard itself may be a little bit slower than the stock one from Arnova. After start-up, in case “SD Card damaged” message will appear, format it. With Wi-Fi connection established, navigate to SuperSU app and update binary(should go automatically) to gain root access.

Tips&Tricks

Improving screen density. 

The procedure(based on the ChildPad, should be simillar for the 8c G3) is explained on our forum. After applying(doesn’t apply for density of 120), don’t clear cache and/or data of Google Play, as not all the apps will be visible then. This firmware comes with default density of 160 and we have found the densities 133,3 and 120 to work too. Find the suitable one for you. ;)

Overclocked kernel. 

JochenKauz built an overclocked kernel for the Arnova 8c G3, you can find it here or in the zip file above. If you want to install it separately or flash back the stock one, it goes pretty easy and takes only a few seconds. First, make sure the tablet is in recovery mode and run the same EvolutionRKTool you used to flash the firmware. Locate the parameter(choose the correct one, corresponding to the one with which you installed the firmware) and the right kernel file and tick the boxes as shown below.

The overclocked kernel provides a ~10% increase in CPU Benchmarks.
