Huge T42G problem
Hi All,

I have a T42G phone.
I have the adminstrator password (previus admin give for me).

Factory reseted the phone and upgrading the top level firmware.
Testing the phone own system. That is the local network dont connect the internet.
The phone was working fine and was happy.

But, when I connected the phone the internet connected network that is reloded the configuration file from previus provider and auto discovered.


Ok, I dont worry I tryed the recovery procedure. (Press and hold the speaker button and bla-bla)

The phone recovered the previous old firmware. (
And after restart or factory reseted newer connecting the previous provider system and don't provisioning.

Ok, I was happy. But I think the is to old.
I upgrading the phone with WEB UI to the next level fw. (

And when the phone restarted again connecting the previous provider. HuhHuhHuhHuhHuh

What is the secret?

Possible the previous provider put the special file, for example the key, to the phone falsh?
How to remove that? Or how to formating the phone filesystem and installing the clear firmware?

Thank you any idea!
