Introduction

Do read all the accompanying notes especially about upgrading from older firmware versions - for example, you are supposed to upgrade from V4 (or below) -> V5 before going to V6,

The notes below relate to the Mitel phones, not the Navigator.

Upgrading

First things first

• Download the required firmware, remembering you may need more than one version to get you to the latest
• Extract the firmware and place it in the download location on your TFTP server. See the notes below if you need some free TFTP software

Then...

Method 1 (seems to work best)

• Login to the Web interface for your phone
• Select the Network Config menu and enter the IP address or URL for your TFTP server
• Click the Save and Reboot button
• As your phone boots you will be prompted to confirm that you wish to upgrade by pressing the star ('*') key

Method 2

• Login to the Web interface for your phone
• Select the Firmware Update menu
• Set Choice of Manual download type: to TFTP
• Enter the IP address or URL for your TFTP server
• Click Update OR Update and Reset Config Files, - noting that the latter will reset all your main settings.

Method 3 (if all else fails or you cannot get to the phone's Web interface)

• Power up your phone with the Super Key (or volume UP key on some phones) held down - this will put you in the configuration menu for your phone.
• Manually setup your network parameters, including the address of your TFTP server
• Save your changes and reboot the phone
• As your phone boots you will be prompted to confirm that you wish to upgrade by pressing the star ("*") key

Notes:

• On more than one occasion, 5220 and 5215 phones have upgraded from V1 and old V4 firmware to the latest V4 firmware successfully, but then have failed to download V5 ('Checksum error'). These phones were subsequently taken directly from V4 -> V6 without any apparent problems.

• If your tftp updates keep failing, make sure that in Network Settings 'Local Tone Code' is set to a valid option - for example CA, US or GB. Also check in Advanced settings that 'Language Code:' is similarly set (en_CA, en_GB or en_US). If not, change these options, save your settings and try again.

• An excellent, free TFTP server (for Windows) can be downloaded from here: http://tftpd32.jounin.net/.

• Non dual-mode (MiNet only) 5215 and 5220 phones cannot be 'upgraded' with SIP firmware (happy to be proved wrong though - if you manage to do this, document it here!).

• As of 14-May-2007 there are no firmware updates for the 5330 and 5340 phones on the Mitel download site.
