Okay so after a lot of research on the web and even after contacting samsung and posting on Android related forums I have come up empty handed. I have a Samsung Nexus S 4G and It randomly started to not load anymore on start up. So I came up with the conclusion it was soft bricked because It won't get passed the Google load screen. Now I took advice and Tried to flash it, but it wont unlock. When I attempt to unlock it the unlock screen freezes after I select Unlock. I have tried various unlock tools but still nothing. If anyone has an Idea or solution please tell me.
