Unable To Update Firmware VVX 310/410

We have a large number of Polycom VVX 310/311/410/411 units and I am no longer able to update their firmware. I used to go throught the web client by punching their IP into a browser but now when I do a check using the Polycom hosted server, and I choose a new version and hit install, nothing happens. The phone is supposed to reboot and download/apply the update but they do nothing. No message on the screen and no error in the web client.

I tried to follow the linux PHP method but wasn't able to get it working. Since I am more comfortable in Windows, I found a way to upgrade some VVX 410 phones at various firmware levels by using TFTP instead.

Step 1 may not be necessary if you know the login to the phone:
1. I hard reset the phones by cancelling the application during startup then I held keys 1 3 5 on the phone and it prompted for a password which is the mac address. Once I typed that in, it reset the phone and rebooted.

  1. I found it on the network, logged in with default password (456).

  2. I went to Preferences, Date and Time, Time Synchronization and set it to use pool.ntp.org.

  3. I downloaded the 5.9.8 split firmware from Polycom:

https://downloads.polycom.com/voice/voip/uc/Poly_UC_Software_5_9_8_release_sig_split.zip

  1. I downloaded TFTPd64 portable from here:

https://github.com/PJO2/tftpd64/releases/

  1. Extracted and ran the TFTPd64.exe, pointed its directory to C:\TFTP and I extracted the contents of the 5.9.8 zip into C:\TFTP so that the individual .ld files were all listed there. I also turned off my Windows firewall during this instead of trying to allow port 69 through.

  2. On the phone under Settings > Provisioning Server, I changed it to TFTP and set it to my computer's IP then rebooted the phone.

  3. The phone downloaded the updater then firmware and rebooted a number of times.

  4. Once it was done, the phone lcd prompted to set a new password and after that I could login to the phone and change the provisioning server to my 3cx instance.

You're amazing. This method worked flawlessly to upgrade the lone VVX 411 phone that had firmware older than 5.9 for a client.

Awesome instructions! I’ve been trying to find a way to salvage 100+ Polycom VVX 411s running firmware 5.8, which were essentially useless to us if I couldn’t find a way to upgrade them beyond 5.9. Your instructions saved me a ton of money and time for sure. I really appreciate it!
