How to Do Firmware Update

You can update firmware through the following three ways:

1. Update through HTTP

On MyPBX configuration page, select System Settings Firmware update, choose “HTTP Server”:
1) HTTP URL: enter the update image file download link.
Example:
http://www.yeastar.com/download/MyPBX-U100_U200/15.19.0.43.bin
2) Click “Start” to upgrade

                                               Figure 1. Update via http
Note:
1. If “Reset configuration to factory defaults” is enabled, MyPBX will reset to factory default settings.
2. If you failed to upgrade through HTTP, please try again by TFTP way.
3. If TFTP upgrade still failed, please turn off your computer’s firewall, and then retransfer.

If the update is successful, you will see the version info on system information.

2. Update through TFTP

Step1. Download the update file. (e.g. 15.19.0.43.bin)

Download link:
http://www.yeastar.com/download/MyPBX-U100_U200/15.19.0.43.rar

Step2. Create tftp Server (For example, tftpd on Windows)

1) Install tftpd32 software on computer
Download link: http://tftpd32.jounin.net/tftpd32_download.html

2) Configure tftpd32
On option “Current Directory”, click “Browse” button, and find where the update file is located, such as C:\Image\15.19.0.43.bin.

                    Figure 2. open tftpd32

    Figure 3. Locate to the folder

Step3. On MyPBX configuration page, select System SettingsFirmware update, choose “TFTP Server”:

1) TFTP Server: Fill in IP address of tftpd32 server, such as 192.168.5.27.
2) File Name: Enter the name of firmware update, such as 15.19.0.43.bin.
3) Click “Start” to upgrade.

3. Update through SSH

We can also update the firmware via putty in SSH.
Step1. Download the update file. (e.g. 15.19.0.43.bin)

Download link:
http://www.yeastar.com/download/MyPBX-U100_U200/15.19.0.43.bin

Step2. Create TFTP Server (For example, tftpd on Windows)

1) Install tftpd32 software on computer
Download link: http://tftpd32.jounin.net/tftpd32_download.html
2) Configure tftpd32
On option “Current Directory”, click “Browse” button, and find where the update file is located, such as C:\Image\15.19.0.43.bin

                   Figure 5. Open tftpd32


     Figure 6. locate to the folder

Step3. Enable SSH access on LAN settings, save it and reboot to take effect.

Step4. Download putty.exe and open it

                                   Figure 8. Log in via SSH

Step5. Log in using the default user name and password

User name : root
Password: ys123456

                                                   Figure 9. Login as

Step6. Input the command in putty:
tftp -gr 15.19.0.43.bin -l persistent/imageupdate/uImage 192.168.5.27

When you see the firmware is uploaded 100%, it means the firmware upload is successful, then input reboot so that mypbx will update automatically to 15.19.0.43.
