Drivers and Utilities
Dragonface (V2.06) for editing firmware for Allwinner processors:
PhoenixCard (v3.09):

Official firmware
Archive with files (not firmware!) On the official DEXP FTP server:…

Unofficial firmware
Firmware self-assembly (img-file):
Linux installation

How to flash:

- you need: microSD on 4GB (maybe 2GB will do - try it), Phoenixcard program (I had version 3.09), img-file of the firmware

1) using Phoenixcard, format and save the img-file to the memory card (the program will do everything itself, everything is clear). Do not expect to see the files recorded on the card, it is formatted in a special way, in a normal file manager, after recording it will be seen as empty - this is normal.
2) turn off the player from the outlet
3) insert the memory card into the card reader next to the USB connector
4) connect a monitor to the HDMI output (it can be done without it, using the flashing green LED on the player's face)
5) turn on the player in the socket
6) the process has started ... (the green LED starts blinking; if a monitor is connected, a green bar-indicator of the firmware will appear on it)
7) when the LED stops flashing and goes out (the strip on the screen reaches the end), wait a while and unplug the power cord
8) remove the memory card and turn on the player again
9) the player should normally boot and exit to the welcome menu with initial settings


For fans to make the firmware "for themselves."
Needed editor firmware for Allwinner processors called Dragonface (see references. Above). On ftp server DEXP, unfortunately, for this model, firmware img-file player not only archived sources. Had with grief in half get on the Internet third-party firmware file for a similar "miracle" SDMC DV7204-T2 (if flash this firmware, our player will not scan the air and show digital TV, even though other functionality is broken will not and it normally sew and will work), and from it by means of the source DEXP-build and self-assembly. This is done as follows.
1) using Dragonface, disassemble the img-file of the third-party firmware (link to file: ).
2) in the folder with Dragonface after disassembly there will be a subfolder / FSOP / SYSTEM
3) unpack the archive from the DEXP-a FTP server (link to the archive:… or a backup link (; you only need the contents of the SYSTEM folder from this archive.
4) now compare the contents of the SYSTEM archive and SYSTEM from Dragonface. All clear? :)
5) now we delete all apk-applications (tab "Build-in APK" in the interface of Dragonface) so that it is empty; we manually clear all odex files in the SYSTEM / APP subfolder (in the Dragonface folder).
6) now through the same interface we install all apk-applications from the SYSTEM / APP folder (DEXP-ovsky archive) instead of the deleted ones; manually transfer the odex files to the installed applications.
7) now carefully look at the contents of the file init.rc (tab "Advanced Settings" in the interface of Dragonface); we see that in it towards the end a certain script is mentioned: in the root of the SYSTEM folder, which for some reason we did not unpack Dragonface.
8) here is the script (link: )
9) copy it to the SYSTEM root (in the folder with Dragonface), where it belongs.
10) You can press the SAVE button (build firmware) in Dragonface.
11) all, we have img-file, ready for firmware (player normally finds and accepts digital TV DVB-T2).

Here you go! Moderators pushed the topic to the back box of the forum. Now without a search you will not find.

The name of the Chinese twin of this device has disappeared from the header: SDMC DV7204-T2, the firmware from which in the form of an img-file is taken as the original.

In the firmware, which is indicated in the topic header as "Firmware-self-assembly (img-file):"I found uncleared odex files (when I unpacked it into Dragonface).
I do not know how much this affects stability, but just in case I cleaned it up and put it here:
For several days, the prefix with cleared firmware works enabled via WiFi with running Orbot (as a repeater), VLC player (Internet radio) and Easy App Switcher. Applications do not close themselves.

DVB-T2 catches and shows me (DVB-T did not try)

By the way, who cares, here is a little modified (changed ExitPolicy from "reject *: *" to "accept *: *" and MORE than ANYTHING!) Orbot, which can be an output relay (Tor Exit Relay):

Unmodified Orbot can only be a non-output relay. The prefix on the passport consumes no more than 8 watts.

Files for unpacking-packing-signing APK-files (one ZIP archive):
You can experiment.

And does the unofficial firmware support the native console?
And yet - in the native firmware I did not understand how to control the mouse - the player does not have any hardware buttons, can I exit the application only several times by pressing "back"?

This is exactly how I use, the remote is on the side.

1. A very useful program for our player (due to the small amount of RAM) - AutoOOMmanager ( Sets the priority for closing applications when there is a shortage of RAM. : yes2: Android has a MemoryKiller kernel module, developed by Google specifically for Android (analogous to the Linux OOM Killer). See info about this module…r-mexanizma-v-android/(if the address will not open, then a copy in the zip here: )

For general development, AutoOOMmanager takes data on the amount of memory from the / proc / zoneinfo directory (opens only as root in the file manager)

2. It was possible to turn our prefix into a wifi TOR-router. Need a bunch of programs Orbot + HotSpot Portable WI-FI 1.1.apk ( ).
In Orbot, we enable traffic via VPN (middle button on the main screen), in the settings we tick "Request Root Access", "Transparent Proxyng", "Tor Tethering", in "Select Apps" we click Proxy All, click at the very end in the settings of "Transproxy FORCE REMOVE". Everything else is defaulted. Now when logging in through our wifi access point, the user has a third-party IP address + you can watch sites on the internal TOR network (sites in the .onion domain)

Not bad, if someone tells you how to set up a wifi access point through the terminal using linux. The wlan0 interface disappears somewhere when I turn off wifi in the settings, I don’t manage to raise via hostapd, and iwconfig is not installed in the system. So the numerous recommendations found from the Internet are not suitable, but the HotSpot Portable WI-FI program and others like it somehow do it.

Can I exit the application only a few times by pressing "back"?

Here is an alternative under the arm instead of MetroUI:, the application switching icon is always on the screen.

And it is interesting - did anyone increase the memory of the RAM? If there is no extra space, then replacing it with more?
And after the question - eternal dependents somebody won ?! For example, the best cooling or the addition of not sealed containers for food or replacing the firmware (on the topic)?

or replacement of a firmvare (on a topic)?

Ask what "zavisony" interested: with DVB-T2 TV or with the rest of the software. What I did with firmware - this action teapot: blush: And these changes can not fix anything. You've got to be able to understand better the software and programming. A climb inside I do not advise - modern installation has become so small, it's easy to box will be in the bin. You've got to decide what you need, if DVB-T2, then buy a simple attachment of 1.2-1.5 tr in a shop, if the rest, then buy Orange Pi in Chinese for the same 1.5 tr with 1GB memory (see. Aliexpress). And I would put our simple Linux console, but have not yet figured out how (routers run on Linux and with 65MB of memory, without graphics)

To solve the issue of memory in android there is a beautiful solution - the redistribution of the built-in memory 8Gb in favor of RAM, but you need to understand how it works and what needs to be changed
I do not understand ;)
However, it was possible to do this on two phones (according to the existing description)
Here is the redevelopment topic.Mobile Memory Markup

Rep: (2)
Question: Why does an extra gigabyte of memory normal RAM (namely RAM) is worth more than 5 thousand rubles even on Aliexpress (compare prices on the devices: tablets, phones, iPods etc with 1GB and 2GB memory).? Because the RAM is almost eternal, but the data is stored only when power is applied (RAM), and those 8GB, that in our set-top box belongs to a different type of memory, as it were permanent storage (stores data without power) and has a finite number of cycles Record- overwriting. Once again: if you want to send the console in a trash can - replace memory (RAM), which in our console 512MB, on the other. Manufacturers are not stupid ...
In most Android devices, there are usually no hard drives, so the amount of RAM (RAM) (we have 512MB) is a determining factor along with the power of the processor when choosing a device, and not 8GB-16GB-32GB-64GB-128GB-256GB ... A different type of memory up to a device price of $ 1,000,000 ...

worth more than 5 thousand rubles, even on Aliexpress

looked, Orange Pi Plus2 costs $ 50. The difference is less, of course, but significant.

Karoch tried to connect the dvi monitor through the adapter

the monitor does not see the console even though it works on the computer

can you be able to flash a thread so that the console can see dvi edid?

Or is there an application on Android for such a connection?

active such adapters as I understood do not exist in nature

It is not clear what-where-how connected. What kind of adapter? Which output from the console, which output from the computer (HDMI, A / V)? etc. A / V - analog signal (sinusoid), HDMI - digital (zero-one levels).

I can not exactly tell, I use the prefix for other purposes. Maybe others will gather and prompt.

Under a little modified firmware from the creator of the topic. I cleaned everything from Google (all their services, I hope. So there is no PlayMarket), a player, a gallery. Brakes and hangs become much smaller. Put IPTV, VLC player, YouTube 5.3.32 (more senior need to google). I put .apk from a flash drive through the explorer in the "Media" menu.
Online video is sometimes buggy, but this is most likely due to the channel.
If anyone comes in handy, use it.

Attention!!! Put at your own risk. If something does not work out, I am not guilty. This firmware works for me about a month.
