Galaxy S3 "Mobile networks" problem.

[Jerms]

Hellow guys, when i go to "Setting" -> "More setting" -> "Mobile networks", it says "unfortunately the process com.android.phone has stopped", so i can't get access to all my networks this setting is very important for me. Did this happened to someone already ? If yes how can i fix this please ?

My Model is "SHV-E210K" (Korean version).
Rooted and 4.1.2 Jellybean version.

Thanks in advance for your answers guys and VIVA PIT SENYOR ! hehe

usually that happens on a corrupted firmware.. either u need to reflash it to the official firmware of your model or lest, you better stick with that error message all the time nalang.
