Cisco SPA525G2

[m4xm0rris]

Hello,

I recently bought a Cisco IP Phone SPA525G2 which is locked with the Vodafone OneNet firmware. How do I remove this firmware to use the phone with my own SIP server as I only plan to use the phone at home and therefore cant use OneNet.

Thanks!

Honestly I'm not sure as I've never used one of those phones.

Vodafone wouldn't assume be able to remove a firmware.

You may get some further advise on the Cisco forum.

This is one thread I came across via a Google Search @m4xm0rris

Hi @m4xm0rris 

The best way to get this solved would be to contact the One Net Team from the contact us link below, they will be able to advise if this is possible.

Vodafone One Net

Also take a look at the unlocking request form below, selecting Vodafone software from the dropdown menu.

Hi

I am not sure if this is relevant any more. You cannot remove the customisation, but you can overide it until you ever need to factory reset the device (in the future). Until then, it can be used with any other SIP account.

I can send you detailed instructions.

Hi

I have been given a couple of handsets by a OneNet client who has been upgraded to nice colour display Huawei handsets. I would like to have a play with FreePBX but also need the admin password to do a factory reset. Can you send to me too please.

hi

if you want to message me i will send you details how to unlock the spa525g so you can get into the advanced menu and to get into admin log in. This will allow you to put your sip providers info in and use the phone on another sip provider.

I created a web-server with the mac address.xml file but there is no profile/provisioning option. I also have a Snom 370 (Vodafone locked) andnd created a DHCP server and TFTP server with the snom370-r.bin (and snom370.bin) but it would not recover from it.

I pretty much tried everything on this project - I can't get into either phone. Vodafone gave me an admin password of 2580 but this doesn't work. They just want old phones to end up in land-fill. Even ones which are obsolute and they don't sell any more, so have no reason to block them from being re-used.

Please could you pm me the admin password?
