I was going to buy the AT&T S4 and unlock for T-Mobile. Does anyone know if the LTE network will work ? I understand the frequencies are different but has anyone tried a different bootloader/modem that enables LTE on T-mobile ?
Thanks again.
It definitely works, I'm doing the same thing.

Just wondering, why would you do this? The i337 has extra bands that you need to flash a modem unlock in custom recovery in order to take advantage of on Tmo. (which if you get an MF3 you're not going to get a semi-proper custom recovery anytime soon)
Is it possible to flash a t mobile modem to my ATT i337 with MK2 through safestrap?
1) questions go in the q&a section
2) if it's a flashable zip then it should work, but I don't know if the modem is compatible, and I actually doubt it a bit.

Maybe I phrased it wrong there was a thread about unlocking the t mobile bands on a att s4 a while back I couldn't do it because of the locked boot loader I was wondering if there is a way to do this via safestrap

Look in the general section, there's various threads about how to unlock the phone but the AWS mod seems to not work on 4.3 which i guess you need for LTE? Someone will have to confirm what that does. But you should still get H+ I believe.

The phone is already unlocked i actually get the LTE but not the h plus which has more coverage in my area

Just search up the T-Mobile APN and see if there's another one that uses H+ or something.
Hello there,
Since the American versions of this phone seem to be bootloader locked, would it be possible to get the Canadian version, on say, Rogers, which isn't bootloader locked, and use it on AT&T? Would I get LTE this way as well? Thanks.
Absolutely. Should work no problem. Just add apn settings and simcard

Sorry to sound uninformed, but what is APN settings? Also, is there a more practical way to get an unlocked version from within the U.S. itself? Such as from T-Mobile?
I sold a Canadian HTC M7 from Telus on the US market with the bootloader unlocked but the new owner could not simply insert his SIM into the phone. It was SIM locked. Locked bootloader is completely different story than locked SIM (the device is locked to work only with a particular carrier's SIM). I had to get an unlock code and then worked. Be aware about this.
Here is your explanation:

I am currently running a G900A (AT&T branded phone with locked bootloader) i am in the process of buying a used S5 but not sure if the bootloader is locked. Here is the phone info that the guy provided to me.
Sm-g900f , g900fxxu1anc9 , 4.4.2
Like i said in on AT&T S5 so i am not familiar with the F models. Any info would be much appreciated.
Is it rootable through towel root? Can i use TWRP or CWM south this device. It is carrier unlocked and he is using it on T mobile (gsm) so I'm guessing it will work on AT&T since is uses GSM as well. Thanks for any help.
Edit: my apologies for posting in the general section. I thought i clicked on the Q/A thread.

Thank you. I've been searching about it and finding a lot of different answers. The T mobile guy at the T mobile store says if i flash a T mobile rom that has the lte band active then i should gain the lte connectivity. Hopefully that's the case. 3g is to slow for me. LOL.

tell him hes a wanker
thats not how it works at all, in fact thatd brick your device
Unlock all bands.
Go into the secret menu. Try downloading Phone Info app for this.
To unlock all the bands try this. Go to UE Settings/Settings/Protocol/NAS/Network Control/Band Selection and select LTE all bands.

To root, use Kingroot+SuperSume+Flashfire
Anyone know which bands are supported by the VZW version? Is it only 2/3/4/5/13?
TIA

I just read about this. According to this review: http://www.pcmag.com/article2/0,2817,2500353,00.asp
"It (Verizon Wireless Samsung Galaxy S7) has LTE bands 2/3/4/5/7/8/13/18/19/20/38/39/40/41. Samsung unfortunately removed key LTE bands for the other major US carriers—12 for T-Mobile, 17 for AT&T, and 25 for Sprint—to make it difficult to use this model elsewhere."
I doubt it was Samsung that removed it - more likely, Verizon had them remove the others. Just a guess, tho.
Is there an ELI5 version of this thread? What is the importance of knowing which "bands" are supported?

Using the phone LTE in other carriers. Carriers 'own' certain frequency bands which are used to communicate with your phone. Your phone and the tower need to be able to use the same frequency band in order to communicate.
Most phones work on 2G/3G world wide (except on CDMA carriers like Verizon, generally most phones don't use the tech/frequencies for verzion nor would Verizon allow then on their 2G/3G bands of they did). But LTE is new enough that most phones don't support the 20 odd frequency ranges used (2G/3G use less then 10 combined for most of the world).

The modem supports all the bands, Verizon disables it in software. What a bummer! I will suggest you to buy G950U or US cellular model.
Or flash the firmware of the carrier you want to enable the modem which has been successfully posted on a few xda threads and other sites. All snapdragon us variants can be cross flashed.

Yes, AT&T bands are in that firmware, evoke TMO bands are in there. Most gsm carriers have all bands except Verizon and Sprint bands enabled

I don't have links to the firmware, I'm at work. If you look at updato.com you can find the latest for the g930a, or you could get the g930u nougat update. There are plenty of threads that work through Odin usage in each forum in the QA
att s8 question

You'd have to check on the s8 forums. An s7 probably would as I think only the Sprint and tmo phones were simlocked. Not sure though as I've only had my ST phone and read the vzw phone being used on several carriers.

So are you saying that the actual bands are software based not hardware based. So all we have todo is flash the right ENG and ROM and wala I have right radios for my carrier?? US Based.
Yes, flashing the fw of the carrier loads the correct radio drivers. The radios are hardware based, but locked down by what the firmware has the instructions to look for and run.

Great explanation, I’m new to this stuff - we all have to start somewhere right?
So is root required to flash? The reason I ask is that I’d like to buy an S7 but I want to be able to WiFi hotspot tether without carrier provisioning and some versions of the phone allow it while I’m pretty sure others block that (like att)...By the way do you know which version would be best to flash to for WiFi tethering and ALL LTE bands made available? Thanks!

I use the hybrid rom that is loaded with vzw and debloated custom to my needs. It has tethering enabled. You'll just need to use root long enough to get the flashfire setup going and then once you're done it is unrooted. You'll have to check other threads regarding performance tweaks if you decide to stay rooted.

I thought the bootloader was locked on the Verizon S7 which doesn't allow rooting?... So rooting actually is possible on the Verizon S7?

Using the engineering kernel for nougat you can achieve toy, but it's buggy and slow since it wasn't meant to be used for daily devices. That's why the hybrid ton was developed to show some root uses without needing to keep root, like removing bloat permanently or getting the tethering service setup.
