A low-cost tablet with 1280x800 IPS display. There is some discrepancy in model numbers (X4, X7, X47) but X47 is what appears in Android.
Identification
This section explains how to most easily identify your device. For a development board, explain the name(s) printed on the board. For an android device, find out the strings as reported under settings.
On the back of the device, the following is printed:
Designed by iRULU in USA Made in China Model X7
The PCB has the following silkscreened on it:
V708_V1.1_0918 MAINBOARD_V1.1 PHT
In android, under Settings->About Tablet, you will find:
- Model Number: X47
- Android version: 5.1.1
- Firmware version: v3.3rc5
- Kernel version: 3.4.39 pht-lzg@Ubuntu-lzg #61 Tue Apr 12 14:34:49 CST 2016
- Build Number: KVT49L.20160412
Sunxi support
Current status
Work in progress.
It is possible to boot mainline U-Boot and stock Debian Stretch R2 armhf kernel over UART using the FEL/USBBoot technique. No devices are accessible, possibly except for the USB port.
Images
Optional. Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be removed.
Manual build
Not attempted.
U-Boot
Sunxi/Legacy U-Boot
Not attempted.
Mainline U-Boot
U-Boot v2016.09 was used successfully with Sinlinx_SinA33_defconfig and microSD UART changes.
Linux Kernel
Sunxi/Legacy Kernel
Not attempted.
Mainline kernel
Use the sun8i-a33-sinlinx-sina33.dtb device-tree binary with microSD UART changes.

FEL mode
Push and hold Volume Up. Push Power and hold for about two seconds. Repeatedly push Volume Up.
It is easier to do this with UART attached.
Device disassembly
{{Easily done with a Plastic tool howto (or a sharp fingernail).}}
Locating the UART
MicroSD Breakout adapter should be used for UART howto. There are almost no test pads on the PCB. Since the built-in U-Boot uses microSD pins for UART, it is unlikely that additional UART pads exist.
Tips, Tricks, Caveats
Do not put sharp objects into the hole marked as Reset because it is actually a microphone. Android is extremely slow on this device.
