N920T unlocked, but now LTE doesn't work


I have a friend on XDA that unlocked my N920T with a GcProKey, and now the phone does not receive LTE service. It will connect to a tower for about 10 seconds, then disconnect. Data in general is laggy.

Can this process be undone?

Can anyone help me?

Hello
Can you tell your friend email address and what kind of usb share tool he used?

gcpro do not have such issue.. only if this unlocked in other tool then you have this issue.

thank you for your reply. there was no problem with GCProKey tool. the problem was with the service provider.

there is no problem with the phone, or the method used to unlock the phone. the situation has been resolved.
