2.4 Button functions and NAND image restore in Android
The following buttons represent functions in the Android:
PWR_BUT
– used to perform software turn off, software turn on and
HOME
– shows the home screen; note that HOME is also used to enter bootloader mode for
firmware update
ENTER
– to select a choice
MENU
– brings up the main menu
VOL+

VOL-

BOOT/REC
– depending on the selection of UBOOT/REC jumper this button might serve either
as the trigger used to enter bootloader mode (for NAND update via the USB_OTG connector) OR
as a recovery button (“wake up” in Android).
It is not recommended to disconnect the power supply (either the USB or the power jack) before
turning off the Android from the either the menus or by holding POWER system written on the
NAND.
2.5 Prebuilt software
The 4GB board-variant comes with Android 4.2.2 ready to use. The default settings of the software
are followed. The Android installed has a built-in support for HDMI monitor and 7'' display (like
A13-LCD7).
How did we install the software? We have configured an Android image with settings suitable for
A10S-OLinuXino-MICRO. Then using LiveSuit tools we uploaded the image to the board via the
USB OTG. The image is available for users to try and tweak the settings. The images can be
downloaded from the wiki article at:

The board variant without NAND needs an SD card with bootable OS – Android or Linux. There
are ready images available for download at the A10s wiki article at Olimex's web site.
To repair the image on NAND re-upload it following these easy steps:
1. Run LiveSuit (can be found in the wiki article for A10s and A13)
2. Disconnect the power supply and USB cable.
3. Place jumper BOOT/REC in BOOT position.
4. Press and hold BOOT/REC button, apply power supply, attach USB cable and release the
BOOT/REC button.
5. You will be asked for drivers for the bootloader. Navigate to the folder where you extracted the
LiveSuit and install the drivers from the respective executables (or manually point the installer to
