OnBox Firmware Replacing via Linux OS

Preparation for Firmware Replacing

Downloading programs

If you did not succeed in replacing firmware on the SD card via Windows OS, then it can be done via Linux OS. If your computer is on Linux-based, then go to "Preparation of the SD card". If you have Windows OS on your PC, install the virtual machine for simulation of Linux OS.

You can download the virtual machine for free here.

It is important to follow the following sequence of actions:

Place the file in Ubuntu and remember its location.

Open the terminal by clicking Ctrl+Alt+T

1. Input the following command

sudo dd if=/home/user/Downloads/OnBox of=/dev/sdd bs=1M

- sudo - command launch as Administrator

- dd - the command of data writing

- if= - the location from where the data must be taken

- /home/user/Downloads/OnBox - the full path to the system image file

- of= - where the data must be witten

- /dev/sdd - the full path to the SD card

- bs=1M - it sets the unit size, i.e. the size of information read/written at a time - in this case, 1MB

2. After inputting the command click Enter. You will see the line for the system password. Be careful when inputting the password as it is not shown in the terminal window. In 5-10 minites you will see the message that the system is copied.

3. Take out the SD card from the card reader.

4. Put the card into the decvice

5. Connect the device to the power supply

7. Connect the device to Ethernet

If the indicators do not light up (see item 7), try to disconnect the device from the power supply, take out the SD card, wait a little and repeat the actions beginning with item 4.

If the device does not work or works incorrectly (for example, cannot be found in the network), try to replace the firmware on the card again.
