Hi, I have a problem where my phone refuses to check for OTA updates as it says it's modified. I also can't connect to Kies. This leaves me with the problem where I've got no way to flash updates. Besides trying to fix Kies (there's enough of those threads already) is there any way I can check for and install updates? I recently updated from 4.0.4 to 4.1.1 and the problems started then, although I'm not sure if I could have done something else.
