Download SlideMe app stored applications and install it...download any application loader from SlideMe , then look for
adb push slideme.apk ( I think that's what it's called ) /sdcard
then go to EsFileExplorer, and install it by double-tapping the apk. Then sign on to SlideMe through the app once it's installed and search for "Quick Settings".
Download and install that app from SlideMe, and once you run it, look for "Airplane Mode". Press that button, and that's it.
From that point thereafter, the wireless GSM radio emulator will be disabled, and should stop seeking signal it'll never find. This increases battery life, as well as give a slight performance boost because you've got one less app that's actively performing a task in the background.
