  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. 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.

  4. 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.?????


    Dupa 2 zile de munca, citit toate saiturile engleze si germane am reusit, am incercat toate
    Firmware si pina la urma am reusit sa gasesc cel potrivit….functioneaza si wi-fi si ecranul (touch screen-ul) foarte bine.

  7. Hi
    got the Rockchip Driver installed used an older Version where you could explicitly choode win7 64 bit. Now I followed instructions and am stuck when I am suppose to erase IDB. Can anyone tell me what I am doing wrong that the utility tells me ERASE IDB FAILED

    • solved the problem did not start the tool as admin
      still it doesnt matter which firmware i use always the same touchscreen never works except the one posted by the admin but with this firmware wlan is not working and the link to the fixed version does not exist anymore
      anyidea when you will solve the touchscreen problem would really like to use the features you put into the release

  8. Hi I have a problem I cant get the childpad in flash mode or if I can then I cant install the necessary USB drivers from the rock tool in order to transfer the firmware to the tablet it tells me always plattform is not supported

    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 ?

  9. 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 : 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.


      • 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 !!

  10. 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!

  11. 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?
