Well, I have carried what I believe are exhaustive tests using 2 BrightBox 1's, one an older Orange-badged BrightBox 1 that I have been using for years and the other a brand-new EE-badged BrightBox 1 that had never connected to the Net from here. Both: Runtime Code Version: v0.09.94.0006-OT (Fri Sep 21 03:00:26 2012).
I carried out numerous Factory Resets, both hard and soft, after setting my credentials in the BrightBox. As long as the BrightBox remains unconnected to the user's BB line, as it would be in someone else's home, then the only credentials you can see are the factory settings of ISP Username = readytoconnect@fs and ISP Password = mistyview. Once it is connected to the BB line, within a few seconds the Remote Configuration (TR-069) by EE, recognising the line, will reinstate the user's credentials. This, I believe, is what's happening to the posters in the other thread finding their credentials returning.
Once the BrightBox has been Factory Reset, the only ways to get the user's credential back is either Restore settings from a saved backup or setting them manually or connecting for a few seconds to an EE BB line and allow Remote Configuration to do its thing. Otherwise the factory settings of readytoconnect@fs / mistyview remain. Should a future buyer of a Factory Reset BrightBox ever connect it to his BB line then either:
- If he is not on EE BB, it will sync but nothing will change and it won't connect cuz the ISP Username can only end in '@fs', or
- If he is on EE BB, it will connect to EE who will Remote Configure the new owner's credentials based on the new owner's phone no.
There were some interesting differences of behaviour between the 2 BrightBoxes when subjected to the http://192.168.1.1/cgi/cgi_wan_eth.js script (ISP user credentials) discovered by ScottHelme :
- On the new router the ISP user credentials were always the readytoconnect@fs / mistyview pair regardless of whether it was factory or user settings.
- On the old router the ISP user credentials were only the readytoconnect@fs / mistyview pair when it was factory reset but,
- On the old router the ISP user credentials were both empty when it was user set, surprisingly.
Mind you this script behaviour may only hold for ADSL not Fibre. Its name implies it is for Ethernet WAN whereas for ADSL you'd want DSL WAN. A Fibre EE user has confirmed that the script does return his true credentials.
Note: The above script does not run under IE; I used FireFox.
