On the back of the device, the following is printed:
NeuTab Model: N7 Pro
The PCB has the following silkscreened on it:
In android, under Settings->About Tablet, you will find:
- Model Number: N7Pro
- Build Number: 723Q6.A33.KK44.V2.31.150610.wsvga.rtl87x3xsvq0
Give a brief overview of the current status of support under sunxi here. If there is mainline support for either U-Boot or kernel, mention this too, but add the extra sections below.
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 left blank.
Add MANUFACTURER DEVICE HW-pack specifics here. This section can be left blank.
Add MANUFACTURER DEVICE BSP specifics here. This section can be left blank.
- For building U-Boot, use the MANUFACTURER_DEVICE target.
- The .fex file can be found in sunxi-boards as MANUFACTURER_DEVICE.fex
Everything else is the same as the manual build howto.
If there is mainline U-Boot support, add this section.
For building mainline U-Boot, use the MANUFACTURER_DEVICE target.Don't forget to add
[[Category:Mainline_U-Boot]]at the bottom of the page.
If there is mainline kernel support, add this section.
Use the FAMILY-CHIP-DEVICE.dtb device-tree file for the mainline kernel.Don't forget to add
[[Category:Mainline_Kernel]]at the bottom of the page.
Tips, Tricks, Caveats
Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.
Through serial console
This method will NOT initialize boot1. For more information on the various ways to enter FEL mode, see the FEL page.
- Power off the device
- Start a serial terminal program (
screen /dev/ttyUSB0 115200for instance)
- In the serial terminal, hold down the 2 key
- Power on the device
The device should eventually print out the following over serial:
HELLO! BOOT0 is starting! boot0 version : 3.1.0 reg_addr 0x01f00100 =0x00000000 reg_addr 0x01f00104 =0x00000000 reg_addr 0x01f00108 =0x00000000 reg_addr 0x01f0010c =0x00000000 reg_addr 0x01f00110 =0x00000000 reg_addr 0x01f00114 =0x00000000 eraly jump fel

This device has root access enabled by default. This means that dumping things like
script.bin from NAND is as easy as:
adbon a PC, enable USB debugging on the tablet, and connect the tablet to the PC via USB
adb pull /dev/block/nanda ./nanda.imgfrom the PC to dump an image of
nandato the PC's working directory
- Power off the device
- Hold down the vol+ button
- Power on the device
- Release the vol+ button when recovery starts

Adding a serial port (voids warranty)
The non-chip/connector side of the board has a number of test pads on it. Solder headers or wires to the pins below the large ground pad on the right side of the board (as seen with the USB port, power port, and power button facing upwards). For more information, please reference the UART howto. Note: the UART pins are shared with the µSD (MicroSD) card pins, so please do not have a MicroSD card inserted when attempting to debug this device with a UART.
