The Arnova ChildPad is an children-optimised Android 4.0 ICS Android 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 is available with capacitive or resistive screens. In addition to our first custom firmware which brings root and Google Play on the device and second one to provide full Android 4.0.4 experience, we are now happy to provide a Jelly Bean custom firmware. Though we developed this firmware with the ChildPad in mind, it should also work on Arnova 7d G3.

Main features:

  • Android 4.1.1 built from Oma JB v1.2.2
  • System in ext4 format
  • CWM Touch Recovery built from Prestigio 5080B
  • Firmware files from 20120608 Official FW version
  • 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 ChildPad 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

AN7DG3-CP20121012OMA4.1 | ONLY FOR CAPACITIVE SCREEN MODEL |

This firmware is specific to the Arnova ChildPad and 7d G3 capacitive screen models 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.

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.

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 is explained on our forum. After applying, don’t clear cache and/or data of Google Play, as not all the apps will be visible then.

Kaspersky Mobile Parental Control.

With this custom firmware, we decided not to install the Mobile Parental Filter app from Profil Technology. If you still want one, we recommend to use the one from Kaspersky, as it is free and has more options than the stock one on the ChildPad.

Setting up parental filtering on Google Play

This custom firmware will open your ChildPad thousands of applications in Google Play, but you may want to enable filtering, so your little ones do not see applications they are not supposed to see.

To achieve this, start Google Play Store, go to the upper right corner menu, click on it, select Settings

Scroll to “User Controls” section, click on Content filtering item

Make sure that only “Everyone” rating is checked.
According to Google, “Everyone” setting should not contain objectionable material, where “Low maturity” setting may include mild cartoon or fantasy violence or other potentially offensive content.

Let us know how it works for you in our Arnova ChildPad forum.

  2. hello, excuse me I’m french and I use a translator
    it’s the same for me locked screen. I had to go on an official firmware, but I’ve lost the detection of network, the tablet is nothing more you can not get internet.
    someone would need an image of a picture chilpad capacitive rom?
    cordially eric

  3. I already installed the previous version (ICS) and now I have Clockworkmod… And now the EvolutionRKTool does not find the device the new JB firmware… anybody any tips and tricks?

  4. Hi everybody! I installed this firmware on my Arnova 7DG3. Unlock after sleep mode really have a bug. Tapping screen spontaneously, or not tapping screen at all. Only reboot solves this problem. Developers, can you solve this problem? I hope that.

  5. Hi all!

    I’ve been trying to get my childpad in flashmode:

    -start rockchipflashing tool on laptop (win7) as admin.
    -connect with usb (it restarts itself after shutting down???)
    -Push paperclip in “reset”
    -Push start button

    tried several combinations (push long and short periods) but nothing helps?
    Chilpad starts everytime in normal mode.?????

    tnx!

    • Hi! Your screen will remain black if you do the right thing, and you won’t be able to distinguish between a powered off device and the device being in recovery mode. The only way to find out is to connect with usb to the computer and it will detect the childpad if you did it right. Hope this helps…

    any idea what i am doing wrong

    • I have a problem. My touchscreen is out of order since upgrade firmware via arctools. But my computers won’t to accept drivers of rockchip to install the CHILPAD in recevoy mode.

      Perhaps USB debugging. But since my screen can be use with fingers, how to do ?
      Thanks.

  10. hey, thanks for your work. unfortunately, all custom roms doesn’t seem to work on my childpad that arrived two days ago. the setup works well, but the touch screen doesn’t recognize anything. same problem using the 404 version. only the official one for capacitive models (Version 1.0 – September 26th, 2012) works. the model no is 502153. any suggestions?

    • i’ve the same pb ! waiting for some solutions ! :)
      Exelletor : did you have any idea ? please :)

      just be carrefull when you downgrad to the official FW from arnova in v1.0 from 26/09/2012 : you will loose all the official apps from the tablet ( all from the android apps !)
      if you want to recover all this apps : go there : ftp://support.arnovatech.com/G3 Android tablet/ and select HDD for childpad ;)

          • :), thx again. got the apps again already. my question wasn’t about on how to install the apps, but if there are any news regarding your custom rom and the touchscreen issues..

            in the meantime, maybe this could be a help for other people as well.. i realized installing (free) apps from the play store using a tool called ‘Real APK Leecher’. it allows you to get the apk files out of the play store. then you can manually install them on the pad.

            cheers

      • Hi Mezcal,

        Could you please explain to me how to downgrade to the official FW ?
        Indeed, after applying this custom rom, the touch screen of my childpad doesn’t recognize anything.
        I tried to put the original update.img in the root of the tablet, but after the reboot, nothing appens ?
        Thanks in advance for your help, cause Santa is looking at me with fire eyes !!

  11. hello very nice guide! ive successfully installed the firmware and its very smooth! thanks to guys. one thing, my problem is about installing Chainfire 3d, the app works well but when i downloaded the CF3D Driver it reboots then few seconds it will freeze on Arnova logo.. someone help me pls!

  12. Hi,
    I have done the firmware upgrade and all went well.
    But now, Applications do not have access to SD Card. I can get there with the bulit-In explorer, but any applications that access the SD Card complaints saying “No External Storage Available”!
    Any help?

    Regards,
    WPrata
