The GXV3000 is an old phone from Grandstream, not anymore in production and supported, but still available on Ebay at a decent price.
It is possible to even find in Ebay "new" GXV3000, i.e. never used before, like one I bought recently as a replacement for a broken one.
So I had to go back on memory lane in order to update the firmware in it to the last available one (high recommended in order to fix the SPIT problem)
Here what is needed to do the job.
Initial requirements
It is necessary to have few things available in order to start :- a GXV3000 (of course)
- a Linux server (probably also a Windows machine acting as server works, but I prefer to use Linux).
Can be a normal PC or a Raspberry Pi or similar small machine - Ubuntu or Debian.
The examples in this article are based on Ubuntu 16.04 LTS running on a System76 server - both phone and server need to be on the same network
Preparing the server
The first thing to do is to prepare the server.
The server has to run the TFTP server, so first of all, install TFTP.
sudo apt-get install xinetd tftpd tftp
This should take care of the installation of the TFTP server.
Be sure to have a directory called tftpboot from the root.
If the installation didn't create one, do it manually as superuser.
If the installation didn't create one, do it manually as superuser.
sudo ls /tftpboot
if the directory is missing :
sudo mkdir /tftpboot
At this point we need to populate the tftpboot with the new firmware for the phone.
The latest available firmware for the GXV3000 family is the version 1.2.3.7 and is still available here : http://www.grandstream.com/sites/default/files/Resources/GXV3000_Firmware_1.2.3.7.zip
Download the zip file and extract it in a subdirectory under /tftpboot.
Below a suggestion about how to proceed. Note, I suggest to create a gxv3000/fw directory under tftpboot because the TFTP can be used also for other settings on the phone, not only firmware, so better to keep things separated.
mkdir test
cd test
wget http://www.grandstream.com/sites/default/files/Resources/GXV3000_Firmware_1.2.3.7.zip
mkdir -p gxv3000/fw
unzip GXV3000_Firmware_1.2.3.7.zip -d gxv3000/fw
Now under the ~/test/gxv3000/fw there are 3 files.
ls ~/test/gxv3000/fw/
boot64b.bin gxv3000b.bin load64b.bin
These 3 files are the ones needed to be loaded in the phone.
To do so let move them under tftpboot
To do so let move them under tftpboot
sudo mv ~/test/gxv3000 /tftpboot
Verify to have /tftpboot/gxv3000 present
sudo ls /tftpboot
Now that tftpboot is populated, start the TFTP server (or restart it if it was already running)
sudo service xinetd restart
The server is ready.
sudo service xinetd restart
The server is ready.
Preparing the phone
Normally the phone by default is coming with the DHCP set, thus just plug in on the network and turn it on.
It should boot and an IP assigned. Wait few minutes since it is possible some old settings are in place trying to update or doing something strange :)
Locate the IP of the phone (usually is on the lower right corner) and on a browser just digit the phone IP address.
It should appear a password request :
Let's hope the default password is set, should be : admin
If not ... well, you need to factory reset the phone (see the section Factory reset below).
If you can log in then ...
After the login you need to go on the tab called Advanced Settings.
Locate in the page the section called Firmware Upgrade and Provisioning
Select the TFTP option and in the Firmware Server path put the address of the server in your network (for example 192.168.1.100) and the path in the server where the firmware exists.
For example : 192.168.1.100/tftpboot/gxv3000/fw).
Then simply select the Automatic Upgrade option on Yes, and Always Check for New Firmware option.
Then click on the Update button (on the end of the page) and when asked, Reboot.
If everything is set correctly, the phone will reboot and will look for the new firmware, starting to download it.
It will take few minutes since the phone has first to download the firmware from the server and then install it in the Flash memory on board.
If everything is OK after a while the phone will reboot with the new firmware.
Repeat at this point what done before (login - go to the Advanced Setting page) and disable the check for the new firmware, also because there is no new firmware available anymore.
Done. The phone now is updated to the latest firmware.
This is important since after the Factory reset the phone will be able to automatic connect to the router and have assigned a valid IP.
The Factory reset procedure is quite simple but there is a trick.
If you have an USB keyboard, connect it to the phone.
It is necessary to enter in the phone it's own MAC address as confirmation for the Factory reset.
Is much easier to digit the MAC address on a full keyboard rather using the phone keypad.

Done. The phone now is updated to the latest firmware.
Factory reset the phone
The Factory reset procedure allows to restore the initial phone setting, leaving it in DHCP mode.This is important since after the Factory reset the phone will be able to automatic connect to the router and have assigned a valid IP.
The Factory reset procedure is quite simple but there is a trick.
If you have an USB keyboard, connect it to the phone.
It is necessary to enter in the phone it's own MAC address as confirmation for the Factory reset.
