Thanks...i changed ro.build.target_operator=GLOBAL
But i cannot find ro.build.factory_operator inthe build.prop
The cust file is empty
so i edited in build prop.
Now LTE option shows up but i only get edge when connected.
1.Your Mobile Phone must be rooted
2.I have Es File Explorer installed.
3.Go in Es File Explorer and search in System/App LteConfigs.apk and LteConfigs.odex and delete or Backup it on the SD Card.
4.Go in File system root/cust/cust.prop, before you edit this file make a Backup and copy the cust.prop in the External Memory.
5. Some version of the phone have two cust.prop, secend you can found on root/cust/OPEN_SG/cust.prop
edit the first and third line to
ro.build.target_operator=GLOBAL
ro.build.target_country=TW
ro.build.factory_operator=GLOBAL
ro.build.factory_country=TW
ro.build.target_region=ESA
Save this and set permissions.
Reboot the Phone
