Downgrade Options

The downgrade from V7 to V6 can be performed in two ways:

  1. Automatic Downgrade
  2. Manual Downgrade (ONLY ADVANCED USERS or ADMINISTRATORS)

Automatic Downgrade

This method automates the downgrade from V7 to V6 FW versions. Use this service as described below.

Setting (provisioning) URL

  • Please be aware that the service will not work if
update_policy = Never Update, do not load Settings
  • Use the following URL for downgrading large numbers of phones to V6 FW version:
http://provisioning.snom.com/from7to6/downgrade.php
  • The phones may then be auto provisioned according the required provisioning scheme (e.g. for snom partner):

Automatic Configuration of the Setting (provisioning) URL using DHCP (Option 66/67)

  1. Set up the DHCP Server for automatic transmittal of the Setting (provisoning) URL.
  2. Reboot the phone which will automatically begin to do the necessary updates one after the other, until it has updated to all current parts of the firmware.

Manual Configuration of the Setting Server URL

Set the Setting (provisioning) URL via the Web User Interface:

  • Reboot the phone. The automatic process starts and all necessary updates will be consecutively downloaded and installed.

Download our Scripts

General Hints

During this downgrade process all required firmware parts will be stored on the phone's flash, i.e. the phone is fully operational after the downgrade and no additional manual update via TFTP is needed anymore. WARNING: Be aware that all previous setting changes will be lost.

IMPORTANT ADVICE: It is of utmost importance to execute step 1 of the following description before continuing with step 2!!! Otherwise it may result in a defective phone!
