The short answer would be to remove the Sprint ROM. I would just wait for it to cancel.
My phone is unlocked already, however whenever I install my T-Mobile sim card it always gives me a wireless handheld activation process... Is there any way to cancel that other than just waiting for it to cancel after a short time?
Did someone submit an unlock ticket for you already?
Do you have a ticket number for me? Or you can message me your name, phone number and account PIN.
The security answer worked. What is the IMEI that you're inquiring about?
Howdy treaken. I'll be more than happy to resubmit a new unlock ticket for you, if that is what is needed. I have seen a couple people state that their LG V20 re-locked to the Sprint network after the phone completed an update.
Reasons for a phone re-locking to a carrier's network are:
* Past due balance on the account
* The device not be paid off
* Phone updates
I sent you a PM to gather a smidge of info.
