Well your posting the verizon section, not att. So if you flashed a rom from this section, you have the wrong radio. Flashing a wrong radio or baseband would not allow you to connect to the data network.

I posted this in the att and was told to post it in verizon cause its a verizon phone... can you help me find the right Rom, kernel, and os that are all compatible?? Please..?

It does not sound like its unlocked.
Who got you the unlock code?
Even though its a verizon phone, your not having issues with the phone, your issue is with the service. I am no longer on att, so I dont know what rom or baseband you should use. I would assume any rom of your choice, but the latest official baseband. As for kernel, I am using kt747.

I had it unlocked in the store, that's why I figured it was right...

What store??? Att and verzion wont unlock a phone. If you know someone with a verzion sim, put that sim in and see if you have data.

Well it was mt friend who works in an ATT store

Put in a verzion sim and see what happens. If you get service, try flashing a rom from att, with an att baseband. Then put in your att sim. If it works, it was the baseband, if not, its not unlocked.

Tmobile to AT&T

I have the LG G3 on a custom Rom for Tmobile. I'm switching over to At&t tomorrow and taking the phone with me. Can I just install a stock based rom over my tmobile stock rom or do I need to follow a method. Please and thank you for any support or point in the right direction.
Its Rooted with TWRP installed already.

Yes you can. But roms don't affect what carrier there on.

Awesome! I never took my phones with me when I switched carriers so I always had to start fresh so I wasnt sure if I needed to go to stock in order to remove any tmobile bloatware.. Thanks

Yeah the rim does not affect the carrier. Why where you running a D851 rom on a D850? Wifi calling?

You dont really need to do anything as TM and ATT use the same LTE bands and share IMEI databsae info. I had a TM note3 that I used on ATT until I got a G3. The ATT sim will register you on the network and you'll want to make sure you have the correct APN settings ( The ATT store can do it while your there or can tell you what's needed) The only issue I had was the TM modem didn't always get great signal and wouldn't place calls in some areas. Not sure of G3 but ATT modem wouldn't flash on my note 3 via odin or otherwise... Cheers!

I have a D851 with tmobile service at this moment

Got a G4 from AT&T and unlocked but with Tmobile network.

So right now I confused about I can't turn on hotspot and never get software up.
Is that because my att phone with tmobile network?
If is please tell me how to fix it? maybe get tmobile rom?
Put an att Sim card in the phone and then it should allow you to update the software

You don't... Rooted and custom rom have nothing to do with using it on another carrier. Sprint is CDMA. AT&T is GSM not possible.
