I Know this is possible but the question to me is how. I have the SPH-l720 and it is unlocked running cyanogenmod 11 and I want to use Tmobile. When I put the sim in it doesnt not register it and when trying to change the network preferences I have no options. Is there a way i could just take the apn setting from the T-mobile rom or anything that will let me connect to the network. Thank you ahead of time:good:
I have a US Cellular Note 4 unlocked.
I was trying to find out if there is anyway to get it to work on AT&T's network.
I know the stock US Cellular rom will not work, since it doesn't have any options for a GSM network.
I was wanting to try another rom, but not sure what to try..
The phone is rooted with TWRP installed..
Any help or comments are appreciated..
Any luck?
I have a verizon S4 that I want to use on the t-mobile network and was thinking about rooting with the intent of installed a custom ROM. My question is can I install the t-mobile stock ROM on it? if not does anyone have a recommendation on what ROM would be good to install in it?
If the phone is locked to Verizon's network only, then you won't be able to use it on T-Mobile not matter how many ROMs you put on it.

Verizon V20 is GSM unlocked from the factory. Did you change the apn settings? Change network settings to GSM if automatic doesn't work?

Hi, yes apn settings are correct . I thinki need help to root my phone
Hey guys, I could use a little help here. I've done some firmware flashing on phones years ago, so I'm not a total noob, just haven't needed to in a long time.
Anyway, I recently picked up an unlocked Sprint S7 edge (was a really good deal) and I'm trying to use it with Metro now. The issue is this. If I set the network to GSM mode, I can make phone calls just fine, but data is totally not functioning. If I switch it to LTE/CDMA mode, the data works beautifully, but I can't make or receive any phone calls. It just instantly hangs up if I try to dial out or goes to voicemail if someone calls me.
I've activated the IMEI with my carrier and verified that the phone is indeed unlocked. I'm guessing this is just some annoying Sprint bug put in there to make the phone not work right on other providers. Any ideas what needs to be done? Do I need to run a third-party ROM, flash a different modem to it? Something else?
I really appreciate any tips here.
What firmware is the phone running?

Hi Ivpre,
Thanks for responding. The phone is running Software version G935PVPU6BRD2, baseband version G935PVPU6BRD2, it's HW revision 7.0 and Android 7.0. Kernel version is 3.18.31-12623509.
I've tried using a few SM-G935U ROMs but they all have failed so far and left the phone in a boot loop. Only by reflashing a Sprint ROM am I able to successfully flash it.
I assume I'm just not selecting or finding a ROM that the same or newer version, as I've read about the downgrade issues with the bootloader. Any idea how to match one? I'd be fine with pretty much any ATT/T-Mobile/Metro ROM since that should fix my issue for the time being. A factory unlocked ROM would be nice though.
I have a T-Mobile Sim (same network Metro uses) in my unlocked Sprint S7 Edge. Network mode is set to Automatic and everything works fine.
Did you Add the APN for T-Mobile? I had to add the T-Mobile APN https://support.t-mobile.com/docs/DOC-28006
And the ALSO add a second APN named internet, with no other values changed. The 2nd one is the one selected, not sure why, but it works that way.
I would like to flash a T-Mobile Rom or the U Rom but they are on Baseband 4, which will not work since our phones are now on Baseband 6(5th number from the right in the firmware version.)
Did you try changing the APN settings?

So you are using the Sprint firmware on T-Mobile? Everything works well? I'm thinking of jumping to cricket this summer, but one phone is stuck on b5 (the other is still rocking 4), so I was a little worried. So basically you just put in the SIM card and added the APN's?

Yes it was working fine with a T-Mobile Sim card and edited APN's. It is now back on Sprint because T-Mobile coverage is poor/non existent inside my work. I will be porting one of my SERO lines to T-Mobile but keeping one with Sprint. T-Mobile only uses Band 2 and 4 where I live, If you live somewhere that has band 12, it may not be unlocked in the Sprint Firmware.
