Device "forgot" my phone number, IMEI out of the blue, can't make calls etc.
I have a Samsung Galaxy Note 3
(Model number SAMSUNG-SM-N900A)
Build number LRX21V.N900AUCUEOC2
Android version 5.0
I've had it over 6 months it worked completely fine then today someone tells me they're calling me and it goes right to voicemail. I notice I can't dial out either.
Upon looking in the settings I notice the device is coming up Baseband version unknown, Mobile network type unknown, Network unknown, service state out of service, mobile network state disconnected, My phone number unknown, IMEI unknown , etc.....
I've restarted the device, waited, turned it back on, nothing changed.
Dialed *#06# it comes back IMEI null ....
I've taken the battery out, removed the sim, waited, reinstalled it and powered on with no luck.
I ran an anti-virus and anti malware program nothing seems to have caused a problem that way and I have no idea how this happened...
I've also tried to do a software update and I get the message "DM initialization is not ready. Check network or SIM card."
When I try to dial out it says "out of service area" followed by "mobile network not available."
It's not a service issue because I'm downtown in my home in a major city and have NEVER had any service issues here before.
I read an article about restoring null IMEI but it was super detailed and I figured I would ask around before going into the command mode of my phone as the article suggests to do.
Can anyone help me?
