Hi folks,

Any advices what to do in next, any tools, instructions to follow up or something?

I bought to my son a device (Arnova ChildPad, AN7DG3-CP, 4GB, capasitive display) which has contained in original package an Android version 4.0.3 and firmware or program version was: rk29sdk-eng 4.0.3 IML74K eng.root.20121030.162043 test-keys.

I followed instructions by i.e. web page '' and now I have a ChildPad which display is totally freezed. Power key is only key which is working.

Firmware what I have used was --> 'kasty-arnchilpadc-40-04'

I have used in installation procedure that 'Easy procedure' selection because noticed when used the 'Rockchip Flashing Tool v1.5' that device didn't get visible in my PC (OS: Windows 7). So I put that new firmware into device internal SD card to the root and after the right boot operation installation went fine.

Unfortunately after that the display as said didn't worked any more.

Please, could you provide me good advices what to do in next. Only good thing is that (I guess) the device internal SD card is still visible via Windows Explorer.

Hope that someone can help me .. ?


EDIT/UPDATED later in here...

Finally I went to forward with my problem. Now I can manage flashing/installation procedure with Alternate procedure mode with my ChildPad within Rockchip Flashing Tool v1.5.

As told me in some other forum topic I have got and received an extremely good web page which is the following kind and key issue go to forward -> ''


In my case the problem was my OS (i.e. Windows 7). It always offered me a some other 'common/global' driver for Arnova ChildPad which is not work. But as told in that web page, you have to remove all drivers from that device and starts from a cratch 'unknown device' you and at least I can magage to flash/install firmware packages to my ChildPad.


Only problem what I have is that, the Wi-Fi is not working. And also that Firmware what should to work with Google Play is still a image, which is not working in my ChildPad (i.e. display was still freezed).


But now, I can try find an other Firmware where hopefully the Wi-Fi is working...

Why did you say that it wasn't the best combination for that device?

I think that now the tab is working and you have the opportunity to install again all the software you desire ;)

You are right morpheus883!

The best thing is now that the ChildPad is working :)

I have forgotten to say .. Google Play downloads also are working.

Now my son has played almost 1 and half day and not seen any problems.

Can't wait a next firmware ..
