currently bootloops the device, just airplane mode with wifi on kind works though.

Disable Cell

• Removes unnecessary apps (Messaging.apk, Dialer.apk, TelephonyProvider.apk, Mms.apk)
• Completely turns off cell radio on bootup
• Installs the radiooptions binary in case your ROM does not include it
• Prevents emergency calls and 911 calls (good for giving your kids your old phone to play with)

Misc

Call ##4636##, tap "Phone information" and (nearly at the bottom) tap the "Turn off radio" button
