My phone was unlocked in Zv8 version but when i updated to zva now it's locked and i updated again to zvc now it shows Invalid sim
Please help here, My LS777 got carrier lock after latest can't access the hidden menu to unlock again with 2945#*777#
I do not have a sprint sim card The phone was unlocked its originally a sprint phone but I was using it with tmobile, after the update the phone got locked
I too have encountered this problem where the phone was network unlocked to begin with, recently it was updated and now it is network Locked.
Sprint gave me an unlock code, but that does not avail any extra menus.
Can user / admin offer a right solution?
you will need a Sprint sim card prior to any agents starting anything. without it nothing can happen.
I haven't seen this happen in a while. I'm happy to check on it for you. I'm going to send you a private message to get your information and the phone information.
