Android 8.1 Firmware and SDK Released for Orange Pi 4G-IoT Board

Orange Pi Development Boards

When Orange Pi 4G-IoT board launched a few months ago, it shipped with a not so recent Android 6.0 operating system. But the good news is that Shenzhen Xunlong Software has now released Android 8.1 firmware for their Mediatek MT6737M quad core Cortex A53 LTE Cat 4 board, as well as the corresponding SDK.

This makes it the cheapest Android 8.1 board with LTE connectivity available on the market so far as it goes for just under $50.

The SDK is a large tarball (22.6 GB) split into 11 smaller files. It’s hosted on MEGA so download is fairly fast, but due to the size I had to install MEGA Sync software in order to download it easily. Once the download is complete, it’s not recognized in Nautilus, but you can extract the SDK as follows in a terminal:


This will take a while and extract over a million files for a total of 64.8 GB. We can now have a look at the code directory of the SDK to find out a bit more.

Both Linux 3.18 and Linux 4.4 kernels appear to be supported, but since Linux 3.18 is not supported anymore, Linux 4.4 should really be the only option here. The exact version listed in the Makefile is Linux 4.4.95. There’s a orangepi directory with some scripts, and other files inside projects and dct directories. I could not find out exactly what those are. The usual instructions to build Android do not work, so instead we have to follow the instructions in the user manual.

On a related note, there also appears to be a low cost Mediatek MT6737 module on Taobao selling for 119 RMB in quantity ($19), which may be used in your own custom hardware with the Android 8.1 SDK.

Thanks to Jon for the tip.

The MT6737M is the same chip that is used in the Nokia 1. And the Nokia 1 is available in a model that supports US/EU bands. https://www.nokia.com/en_int/phones/nokia-1 I’ve ordered one to check it out.

(LAM AND AUSTRALIA regions – GSM850/900/1800/1900. WCDMA 1,2,4,5,8. LTE cat4, B1,2,3,4,5,7,8,20,28,38,40),
B2/B4/B5 are the main US bands.

The advantage of getting a Nokia 1 is that you will have a touchscreen, battery and camera to work with. The single USB OTG port on the MT6737M means that if you want to use OTG adb you can’t have a keyboard/mouse plugged in. That makes it difficult to work on the IOT-4G. With the Nokia 1 you can use adb over OTG and then interact with the touchscreen.

It should be possible to use adb over the wifi connection on the IOT-4G thus allowing a keyboard/mouse but I haven’t made it that far yet.

Also, consider using this chip without the cellular support. The chipset is priced almost identically to the Allwinner A64 when you factor in SOC + PMIC + 2.4/5Ghz wifi. And you get Android 8.1 instead of some Android released in the last century from Allwinner. The MT6737M is more expensive than the A64, but the companion 2.4/5Ghz chip is cheaper which negates the more expensive SOC. Plus the GPU is way better – Mali-T720 MP2

I have checked and the MT6737M on the 4G-IOT does support 1080P h.264 encoding.

Note that there are many versions of this chip with varying features – MT6737, MT6737T, MT6737V, MT6737M. I have not discovered concise documentation on the differences.
