Not sure if this has been addressed or not. I was not able to locate it in any searches.
The Samsung T919/F480 on the T-Mobile network has been locked down pretty tight, to the point where you cannot change the lock screen wallpapers (flowers, feathers.

) A lot of users on another forum have been trying different methods to get rid of these image files with no success. Is there some way to get into and modify the phone file system without flashing the firmware? Getting the phone into boot loader mode and installing the proper Qualcomm drivers at least shows the port in TK File Explorer, but the computer still cannot connect to the phone.
Other forum members are also looking at changing the nv_default.ini file settings. Some are speculating this phone has a wifi chip, but the feature has been disabled by the carrier. Can anyone confirm this?
Thanks for any input.
