I don't know what happened really, but I have a 7290 which when it comes on it displays the 507 error and go off shortly, most of the time it wont come on.
So i got here and read through this page and wanted to reload the firmware/OS but I can't because it wont even get detected when i connect it to any PC via USB, and it doesn't even show that it's charging or what, it's just there. What could be the problem?
BTW; I use to use my local provider called Vodacom-TZ but the phone has a T Mobile label at the bottom front. What am I missing, how do i fix this?
