Download Android 7.12 Nougat for Orange Pi PC Allwinner H3

Android Nougat 7.12 for Allwinner H3 single board computers like the Orange Pi PC

I recently purchased an Orange Pi PC and I have spent the last couple of weeks playing around with different operating systems for this low cost mini computer.

For it’s price (around £15 delivery from China) the Orange Pi PC packs quite a reasonable specification, it has 1GB of DDR3 RAM, a quad core Allwinner H3 CPU, 3 USB ports, 10/100 Ethernet, and a 40pin GPIO header.

There is no onboard storage so you have to boot from mini SD card to get any OS onto the Orange PI. Although there are plenty of operating systems to download from Orangepi.org I found that most of them are out of date or in the case of the Android builds which they have a Android 4.4 and Android 7 beta they are in Chinese and don’t come with Google apps installed. And in the case of Android 7 I struggled to get it to run stable.

I had tried a community build of Android 4.4 Kitkat called H3droid which was in English and had Gapps and worked quite well. But Android 4.4 is quite an old version of Android now and I expect soon app developers will stop supporting these old Android versions which will limit the number of apps you can run.

I looked around for a English version of Android 7 with Gapps and found a blog post from MQXproject about an Android 7.12 version for the Sunvell H3 TV box which uses the same Allwinner CPU as the Orange Pi. On that post they reported that the software for the Sunvell H3 also works on the Orange Pi PC.

I therefore decided to try to download and flash it onto an SD card and test it on my Orange Pi PC. This proved to be initially quite difficult as it requires using the Phoenixcard software to flash the image, and this software only works under Windows and many users report difficulty in getting it working.

I was one of these people who struggled with Phoenix card software trying to flash the image on to a SDcard using a Windows 10 PC. The Phoenix card software installed Ok with no error messages but following the instructions on using the software I received an error ‘load cardtool failed’ whenever I tried to write the image to the SD card.

I was having difficulty finding a solution to the Phoenixcard error load cardtool failed. I knew that the SD card or USB to SD card adapter were not faulty as I had successfully burned other images for the Orange Pi using Etcher.
I did eventually resolve it thanks to a posting on a forum which advised to install the Microsoft Visual C++ 2008 Redistributable Package (x86). After this software was installed and I ran Phoenix card tool again it flashed the image without an issue. So if you are experiencing issues with Phoenix card software then I advise installing the Microsoft Visual C++ 2008 Redistributable Package (x86). before you start trying different SD cards or thinking the download is corrupted.

Once the image was flashed onto the SD card I proceeded to boot up my Orange Pi PC with it, initially boot did take a while (probably about 5 minutes) but obviously that will depend on the speed of your SD card. Once it has booted up it will come up with a customised Android home screen. (see below)

The software pre-installed on the image is pretty basic, You get Google Chrome, Firefox, Netflix, Miracast receiver, Music app, KDplayer which is a build of Kodi 17.5, a File manager and Youtube. But it does have the Google Play store so you can download other apps. And although I did have a couple of apps say they were not compatible with the box most of the apps I have tried installed ok.

Although the software works well on the Orange pi it is not quite perfect and there were some issue I noticed during my testing.

• It doesn’t recognise any USB Wifi dongle I have tried connecting up to the USB ports. Therefore I am guessing either it will only work with a specific WIFI adapters or perhaps it doesn’t have any USB Wifi support installed. USB WiFi adapters I tested on it had Ralink 3070 chip and one with a Ralink 5370 chip. These usually no problem under Linux as the driver is built into the kernel. But on this Android build although they are detected as being present if i run Aida64 and look under devices. But no Wifi networks can be found when you switch on Wifi in Android and do a search. The onboard Ethernet does work so you can connect to the internet with it via a wired connection as a backup option
• There doesn’t appear to be anyway of shutting down or powering off from within Android. It does shutdown if you press the power button on your Orange Pi PC but then I found it wouldn’t power back on again until I removed the power adapter and put it back in.
• A final thing to note is about the speed of your SD card, this doesn’t just apply to this Android version but in general when running operating systems from a mini SD card.  The manufacturer of the Orange Pi advised you use a card with a speed of at least class 10 – which should provide 10Mbs write speed – with whichever OS you are running on your Orange PI.
  I was using a class 10 rated SD card but found loading apps seemed to be slow under Android and installing apps from the play store also took ages. So after some googling I found a tip to use a card that was not only rated class 10 but also had an A1 rating.
  The A1 rating is not just about read/write speed but more to do with I/O and how well it can handle loading apps and will give you a better experience on something like the Orange Pi where it can be a lot of small files being written to the SD card.
  After switching to an A1 rated card (In my case a Kingston Canvas React 32GB) it made Android on the Orange Pi a lot more pleasant to use. Apps load up very quickly now compared to what they were doing on a standard class 10 SD card and generally responsiveness is improved. From now on I will only be using SD cards with an A1 rating on my Orange Pi.

It may also work on other Orange Pi models or other single board computers with the Allwinner H3 CPU but I have not tested it on anything else due to only having access to an Orange Pi PC. If it does successfully work on a different single board computer please leave a comment to let me know.
