This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

If a device is special, then feel free to provide a terse description of what makes this device so special. But terse, no novels, no marketing blurb.


This was sold in two versions with the main difference being the functionality of the remote IR controller. Very similar to Miniand Hackberry (1GB RAM version) and the images for the Hackberry work on this unit as well. Supplied with Android 4.0 that could be updated with various versions released by Justop (by the administrator Justin) on their old forums with the latest being "JUSTOP_A054_V1.8.1_20130809_ytb_fix_old_remote" or "new remote", depending on the hardware version). The forums are active again on https://www.tapatalk.com/groups/justop/ (as of July 2020) but all the old messages are gone.

Sunxi support

Current status

Give a brief overview of the current status of support under sunxi here.


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.


Optional. Add MANUFACTURER DEVICE sunxi HW-pack specifics here. When empty, this section can be removed.


Optional. Add MANUFACTURER DEVICE sunxi BSP specifics here. When empty, this section can be removed.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.


Sunxi/Legacy U-Boot

Use the MANUFACTURER_DEVICE build target.

Mainline U-Boot

Use the MANUFACTURER_DEVICE build target.

Linux Kernel

Sunxi/Legacy Kernel


Mainline kernel

Use the FAMILY-CHIP-DEVICE.dtb device-tree binary.

Tips, Tricks, Caveats

Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.

FEL mode

The FEL mode can be triggered by shorting the two pads on the button K9 marked as FEL (see adding a serial port section below) or by sending number 2 over serial after powering on the device. Both trigger FEL but the second method provides initialization of the PIO according to "script.bin".

Device specific topic

If there are no further device specific topics to add, remove these sections.

UART pads

UART howto

The picture shows the serial port at the bottom. Pins left to right are:



- 3.3V

- RX

- TX

Device disassembly

If necessary, provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped. If pins do need to be popped, mention the Plastic tool howto.

Locating the UART

Describe how to find the RX,TX,GND signals here, and mention the UART howto.


Take some pictures of your device, upload them, and add them here. DO NOT UPLOAD PICTURES WHICH YOU PLUCKED OFF THE INTERNET.
