My friend got a used SM-G920R4, has AT&T, and wants root. I want to get the AT&T stock firmware to put on it, then root it. The sim works once AT&T settings get added to the network list, however mobile data doesn't work. He is running Android 6.0.0 and has an unlocked bootloader.

Droid V: 4.2.2

My Girlfriend bought me the new Verizon Samsung S4....not knowing that each phone is "tailored" for the carrier. She used her upgrade for me for Xmas and instead of telling her "i cant use it" and have her feel bad, i would like to Flash a T-Mobile Stock Rom onto the S4.
I currently have my T-Mobile Sim card in the S4, and it actually does work for Voice Calls, but Data wont work. Ive tried configuring several different APNs to it (per T-mobile's website). But i still just cant get Data. I also can not get "wifi calling" because Verizon's Rom does not offer it.
So quick questions:
-Do I need to have Root in order to Flash my Verizon S4, with a T-Mobile Rom. I am assuming Yes.
-Would any T-Mobile, Stock Rom, that works with android 4.2.2 be compatible?
IS IT AS EASY as i am hoping? I am not shy to the Rooting/Unlocking world, so if its possible, i will get it done.
Here is your fix

MY sister called ATt to unlock her phone when she went abroad, they did. Now she no longer has ATT and is with tmobile. Using the Tmobile sim card, she can't seem to upgrade her OS using the firmware update option in settings. How can she go about upgrading? she currently has android 4.1.2 with the NOte 2?
also if i flash aokp on her phone, but she don't like it, then flash back the original 4.1.2 firmware, would i lose the unlock that ATT did for her and she can't use Tmobile anymore?

Carrier unlocking is separate from ROM. If you can install custom recovery (CWM, TWRP), switching from ROM to ROM is as simple as doing a backup of one, wiping the device, and installing another ROM. Always save a back-up to your computer, and it's also a good idea (much easier in the end) to do a batch back-up through Titanium of all the user apps, so you can simply restore them to the new ROM instead of downloading them all over again and losing the app data.
Factory firmware can be obtained from sammmobile.com and are flashable with Odin (google it).
thanks for the help but why can't she update the stock rom from the settings though when she switched to tmobile? are the update locked to the att carrier?

I wouldn't worry about it too much. The method Planterz gave you will give her the latest firmware. There's at least a few Lolipop ROMs for the Note 2

Unlocked D850 for TMO now I can't get LTE with AT&T, TMO LTE works fine. I have both AT&T and TMO sim cards . I'm running Stock KK rooted . I did upgrade to lollipop and still no LTE on AT&T, but lost root so I downgraded back to KK via LG Flash Tool.
I tried a few different APN's with no luck. IDK any help would be appreciated

Which APN's did you try??
I tried the nxtgenphone that was the default one when I put my AT&T sim in. Also tried "phone", this one I get 4g but not lte. I also found one that was either "pto" or "pta" I think it was "pta" this one I get no data at all, same with the "nxtgenphone"

Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
Have an unlocked tmobile s8 active I'm using on the AT&T network that I'd like to be able to use wifi calling on cause i get lousy cell reception at my place, is it possible to flash the AT&T fireware onto the device? ive already tried using odin and the stock AT&T 8.0 android oreo firmware i found in a different thread but it fails.
