LG V20 unlock problem

Re: LG V20 unlock problem

Some times ago I've bought on eBay this phone. The seller said that phone already unlocked. But when I try to use non-Sprint sim card I always get "Invalid sim".

Updating PRL, Profile or unlocking UICC always crash with authentication error.

I've tries several times to chat with Sprint support. But they always told me that phone already unlocked and they can't help me.

I tried to do ##72786#, but still nothing.

Android version Oreo.

On XDA forum I found one topic where I guess that only Em_Will_I_Am can help me.

Re: LG V20 unlock problem

since the phone is no longer on an active line any unlock signal Sprint kicks to the phone wont make it unless the Sprint sim card is still in the phone...its turned on...and its connected to wifi so it can actually receive the signal..were these done previously?

Yeah, do you have a Sprint SIM?
