Does anyone have a method to completely turn off the cell radio, while leaving Wifi and Bluetooth intact?
To trim expenses, I've just switched my phone service to a "dumb" phone, and intend to keep using my OG Droid (SS 5.2) as a Wifi only device. Airplane mode disables Bluetooth, which doesn't work for my needs. I can use the Phone Info app to turn off the cell radio, but it doesn't stick after a reboot. I saw an XDA post mention renaming /system/app/phone.apk and /system/app telephonyprovider.apk, so I tried it. The phone went into a constant FC loop of the phone app, and pulling the battery didn't help, so I had to restore a backup.
Is there a better/easier/permanent way to do this?
