So After a long time I've created this mod for xda . I want to share with you a mod which will enable dialer(SecPhone.apk) on your WiFi only Tab 3 10.1 . Don't try it on any other device or you'll get a soft brick (not even on other variants of tab 3) . It can be only used for dialing USSD codes.
I am not responsible for bricked devices, dead SD cards. This mod is only for Kitkat 4.4.2 . Don't dare to try it on 4.2.2 or you'll get soft brick.
1)Download the framework-res.zip
2)Unzip & Extract Framework-res.apk
3)Copy it and paste it in /system/framework/'here'
4)Change permission & reboot .
5)Tadaa...... You'll see Phone icon in the launcher.
