Image works with SD cards and USB drives. Regular firmware in the device is NOT CHANGED. When you replace the dtb file can be run on any device with Amlogic chip S905 s905x s912   When you first start the system, the root user password is 1234   The minimum media size - 4 GB     Option how to start (Activation multi-boot).  
****************************************** Manual run Systems ******************************************

Now all images Armbian and LE has all the files for activate the multi-boot. Anything in addition to download and copy to media is not required.

1. Download the desired image
2. Unpack
3. Record an image on the medium
4. to run Android
5. open the app "Update&Backup"
6. Select local update and an archive on removable media (
7. Run update
8. System twice to reboot and start running the system from external media.
9. If after 7-10 minutes on the monitor not to receive any messages on system startup. Turn off TV box and add in manual in the first partition (FAT) the file "dtb.img". On the media there is a directory dtb from where you can take the files and copy them to the root of the renaming of "dtb.img".

Need to pick up the option for the file system will run. Pay attention, after you add\change the dtb file, you need to try to run the system and waiting to run 7-10 minutes. If not happened, repeat with a different dtb file.

Attention !!!! On models with S802 S805 S812. Activation multi-boot is possible ONLY with SD card (activation of the USB stick is NOT WORKING). After a one-time activation procedure is multi-boot, run a variety of systems is possible from ANY storage media (SD cards and USB storage devices).   ************************************************** ************************************************** *******   The choice of shell to start (Mate\XFCE or KODI).   On the screen enter username and password (in lightdm) in the upper right corner of the screen there is a menu where you choose which GUI to run. The list will be three items (two rows with kodi) and the last line mate. Select mate (something opposite mate was the point), then enter the username and password. The system remembers the last selected mode. If at the next login or what not to choose in this menu, system at the entrance will trigger the option that was turning off in the previous session.     Install to eMMC (NAND)       To install Armbian in the internal memory, you must execute multiple commands. We strongly recommend TO PreRUN create a full backup of the entire contents of the internal memory. This will allow you to return to the current state of the firmware at any time. To create a complete backup you need to execute commands.   su -
(enter passwd root)
ddbr   The running tip backup script   After creating the backup, to install to internal memory (eMMC) of the command being executed
Pay attention, if you not are sure that you will be able to solve possible problems from the installation of the internal memory (eMMC), do NOT PERFORM these commands.   su -
(enter passwd root)
./ or nand_sata_install     Setup HDMI out.   The configure script video output reside in a directory on a FAT partition (on a running system, this partition is automatically mounted to the /boot directory). This script can be changed. To change the screen resolution from 720p to 1080p, you need to uncomment the line "#mode=1080p60hz" and comment out the line "mode=720p60hz". Similarly, you can change the color depth from the default 24 to 32 (bpp=24). Note that with 32 bit color significantly changes the desktop. In this script you can place the commands you want to run WebMin , Doker, ask line to run the USB port (if necessary), configure, sound card, etc.   On Wifi.   run as root user one of these commands in the terminal An example command to load module “dhd” or “wifi_dummy”   modprobe dhd   or   modprobe wifi_dumm   After verification of the selected module, if everything is working correctly, you can add it to the autorun list (add string name of the module in the file /etc/modules).     Remote control.   Added support for remote control. To use it you need to add the correct file “remote.conf” in the /boot directory or /etc/amremote. By default, a part of the image includes several predefined files (in the /boot directory). To use it you need to rename one of the files in “remote.conf”. Additionally uploaded the site to the directory the deb package “amremote.deb” , which can be installed in the old system (do not download the whole image). After installing this package you need to run service “amlogic-remotecfg” and add (rename) the correct file 'remote.conf".   Auto login   Add line to /etc/lightdm/lightdm.conf.d/11-armbian.conf   [SeatDefaults] autologin-user=username autologin-user-timeout=delay     Additional information       Wiki Information to enable multi-boot on the WiKi is outdated, use to activate the multi-boot description from this post in the beginning.    Other versions of images with different Linux systems.
