GRP26xx - Firmware Upgrade Guide

  • Updated on May 26, 2022

All Grandstream products’ firmware are improved and updated on a regular basis. Latest firmware versions are available in http://www.grandstream.com/support/firmware

Published firmware versions in Grandstream official website have passed QA tests and included new enhancements implemented, reported issues fixes for better user experience; all changes are logged in Release Notes documents.

Provided Firmware package is specific to a single product or product series, same as release notes document. For example, Release_GRP260x_1.0.1.50.zip and Release_Note_GRP260x_1.0.1.50.pdf are specific to GRP260X Carrier Grade IP Phones.

Grandstream recommends reading Release Notes document which may include special firmware upgrade notices, and always keep your devices up to date by upgrading their firmware versions regularly.

This document describes steps needed to upgrade the GRP26XX devices firmware version and covers the following scenarios:

  • Scenario 1: Upgrade using Grandstream Public HTTP Server.
  • Scenario 2: Upgrade using a local Server.
  • Scenario 3: Upgrade through Manual Upload .
  • Advanced options.

GRP26xx series include GRP260x and GRP261x series as well as GRP2624 and GRP2634.

Scenario 1: Upgrade using Grandstream Public Server

Grandstream is hosting latest firmware files in a public HTTP server so customers can use it to directly upgrade their Grandstream devices with latest firmware. The same server also hosts BETA firmware when available.

Follow below steps to successfully upgrade your device:

  1. Access web interface of your device and go to Maintenance 🡪 Upgrade and Provisioning (For the GRP260X, Go to Provision TAB ).
  2. Make sure to select “Always Check for New Firmware” for “Firmware Upgrade and Provisioning”.

  2. Reboot the device and wait until the upgrade process is completed.

  • Internet Access is mandatory for the upgrade using Grandstream HTTP server.
  • To upgrade to BETA firmware (if available), use “firmware.grandstream.com/BETA” in step 4.

Scenario 2: Upgrade using a Local Server

Customers can use their own HTTP/HTTPS, FTP/FTPS or TFTP server to upgrade Grandstream devices.

To achieve this, first download firmware files for the appropriate device model from http://www.grandstream.com/support/firmware. Unzip downloaded package and put extracted files in the root directory of your server.

  • Devices and your server need to be in same LAN.
  • If using remote server, make sure to open/redirect ports in your router, so devices can download firmware files from it.

Reminder

HTTP (TCP) default port is 80, HTTPS (TCP) default port is 443 and TFTP (UDP) default port is 69.

Local Upgrade via HTTP Server

Please refer to the below steps for a local upgrade using HTTP File Server tool.

Installing HTTP Server and Uploading Firmware File(s)

  1. Launch the install wizard of the tool once it is fully downloaded.
  1. Click on Run to launch.
Figure 5: Starting the HTTP server
  1. Once HFS starts, browse and select the firmware files from your local directories.
  • Under Menu 🡪 Add files.
Figure 6: Selecting the firmware file to upload on the HTTP server.

  1. Select the file(s) and click Open to upload the file(s) to your HTTP server.
Figure 7: Uploading the firmware file to the HTTP Server.

  1. Once uploaded to the HTTP server, the firmware file should be available on the link: “http://192.168.5.218/grp2600fw.bin“ Next to Open in browser. As shown on the screenshot:
  • 192.168.5.218 is the IP address of the computer running the local HTTP server.

Configuring Grandstream devices for local HTTP upgrade

Configure Grandstream devices to upgrade the firmware via HTTP by doing the following:

  1. Access the Web GUI and navigate to “Upgrade and Provisioning” page.
  2. Set “Firmware Upgrade and Provisioning” to “Always Check for New Firmware
  3. Go to “Firmware” section,
  • Select “HTTP” for “Firmware Upgrade via”
  • Enter the path (IP address) of your HTTP server containing the firmware file under “Firmware Server Path”.
  1. Press “Save and Apply” at the bottom of the page to apply the new settings.
  2. Reboot the device and wait until the upgrade process is completed.

Notes:

  • In our example, we have configured the firmware server path as: “192.168.5.218“.
  • Make sure to not include leading http:// in HTTP Firmware server path.
  • You can verify the upgrade progress on the HFS Server as shown blow:

  1. Start Apache module in order to use the HTTPS server.
Figure 13: Apache Module Started
  1. Access the XAMPP root directory on your computer and put the firmware files on the following path: “C:\xampp\htdocs\xampp
Figure 14: XAMPP Directory
  1. To list all available firmware files on the root directory, access the local link address “https://127.0.0.1/xampp/” from the computer running HTTPS server.
Figure 15: Index of XAMPP Files

XAMPP has a built-in SSL certificates for HTTPS access. Changing the certificates, is possible by a simple copy/paste of the generated certificates on the following folder: “C:\xampp\apache\conf “. The folder contains 3 sub directories: ssl.crt, ssl.csr and ssl.key.

Important:

Do not close the browser when performing the Manual Upgrade.

Advanced Options

Automatic Upgrade

Automatic Upgrade allows to periodically check if a newer firmware is available to download and upgrade the device. This option will help to keep the devices up to date. It can be enabled from web GUI 🡪 Maintenance 🡪 Upgrade and provisioning page.

For the GRP260X you need to navigate to Maintenance 🡪 Upgrade and provisioning under Provision Tab.

Figure 31: Example of Configuring Automatic Upgrade for GRP261x, GRP2624 and GRP2634

The automatic upgrade can be configured based on following parameters:

  • Every [Time interval] in minute(s)
  • Every day (“Hour of the Day” should be configured)
  • Every week (“Hour of the Day” and “Day of the Week” should be configured, 0 is Sunday)

The device will check the firmware file availability in the specified time interval. If found, it will be downloaded, and the upgrade process will be initiated automatically.

Note:

For the GRP260X, in order to have the access to edit the check for the firmware schedule, we will need at first to change the Automatic Upgrade from No to one of the following :

  • Yes, check for upgrade every Minute,
  • Yes, check for upgrade every Day,
  • Yes, check for upgrade every Week.

And then we can adjust the settings according to our deployment and our needs,

Firmware File Prefix and Postfix

Firmware prefix and postfix are two options which can be configured by users to lock the firmware update, then only the firmware with the matching prefix and/or postfix will be downloaded and flashed into phone.

Firmware file prefix and postfix can be configured from Web GUI 🡪 Maintenance 🡪 Upgrade and provisioning.

For the GRP260x, this can be found under the Firmware Tab.

Use Case Example:

Using firmware prefix and postfix, users store different firmware versions in same folder and only upgrade to specific version.

  • If Firmware File Prefix is set to 1.0.0.31 on a GRP26XX series phone, for example, requested firmware file will be 1.0.0.31grp2610fw.bin
Figure 35: Configuring the Firmware File Prefix

  • If Firmware File Postfix is set to 1.0.0.16 on a GRP26XX series phone, for example, requested firmware file will be grp2610fw1.0.0.16.bin
Figure 36: Configuring the Firmware File Postfix
Figure 37: Firmware Files with Prefix/Postfix on local directory

HTTP/HTTPS User Name and Password

HTTP/HTTPS User Name and Password need to be configured if HTTP/HTTPS server requires authentication to access and download firmware files.

To begin firmware upgrade process, the phone sends an initial request to download firmware files from the server, the request will be challenged by the server to provide valid credentials, the phone sends same request including configured HTTP/HTTPS User Name and Password, if accepted, firmware upgrade process can start.

If Always Authenticate Before Challenge is set to “Yes”, the phone includes configured credentials in initial request to download firmware files before being challenged by the server. The default setting is “No”.
