1. Download the desired firmware from the support website.
2. Unpack and edit the Config-eSpace7910.xml file with an advanced text editor like Notepad++.
Let's look at the section Account1 from the file.
<InternetGatewayDeviceConfig xmlns="urn:dslforum-org:cpe-device-config-1-0">

3. Mark the lines that require changes, in this case we will only mark the DND, CFU and CFN lines.
<DND ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*56#" DeactiveAccessCode="#56#"/>
<CFU ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*57*" DeactiveAccessCode="#57#"/>
<CFN ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*41*" DeactiveAccessCode="#41#"/>
4. Remove all the lines that don't require any changes / update / modification and leave only the required information.
<InternetGatewayDeviceConfig xmlns="urn:dslforum-org:cpe-device-config-1-0">
<Device>
<UserCfg>
<Account1 Enable="0" Account="" LogOut="" LabelName="" UCAccount="" PGMNumber="" CorpID="" PhysicalLocation="" JointUserNum="">
<Service>
<DND ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*56#" DeactiveAccessCode="#56#"/>
<CFU ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*57*" DeactiveAccessCode="#57#"/>
<CFN ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*41*" DeactiveAccessCode="#41#"/>
</Service>
</Account1>
</Device>
</InternetGatewayDeviceConfig>
5. Change the header to <InternetGatewayDeviceConfig TimeMark="">, add MFlag="1" after the service / function / option marker (example DND, CFU and CFN) and make the changes that you need.
<InternetGatewayDeviceConfig TimeMark="">
<Device>
<UserCfg>
<Account1>
<Service>
<DND MFlag="1" ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*123#" DeactiveAccessCode="#213#"/>
<CFU MFlag="1" ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*124*" DeactiveAccessCode="#214#"/>
<CFN MFlag="1" ServiceRight="1" ServiceRegister="0" ActiveAccessCode="*125*" DeactiveAccessCode="#215#"/>
</Service>
</Account1>
</Device>
</InternetGatewayDeviceConfig>
6. Save the file as 'defaultMFG_cfm.xml'.
The example below is of a more complex defaultMFG_cfm.xml file:
