I have the samsung S2 with virgin its is suppose to be model sph-d710 but I messed up and ended up flashing the wrong software. The model number is now sch-r760x. Android version 4.1.2.. GB28 I did the the download from Samsung's web sight How do I get it back to the correct model. For the most part it works, it has a few issue, I am unable to send pic text. The volume does not work correctly. I have tried to use the simple download tool but my phone will not connect to it. Samsung Kies, will not connect and it then tells me to down load kies 3.0 When I tried that it more or less said its not the right device. Both Samsung and Virgin mobiles tech support is well other then helpful. I hope that someone can point me in the correct direction, in order to get this solved.
