Hey guys, since T-Mobile has unlocked bootloader, are you guys able to flash other carriers roms like at&t?
I'm only asking because im on an AT&T model, but eventually want to flash T-Mobile roms once our bootloader is unlocked for wifi calling.

It would require some tweaking, but in the base idea, yes, they're all the same (with different radios and likely different kernels). You'll want to just wait a little bit and have devs port to the other models. However, your goal of getting wifi calling likely won't work. Maybe I've been out of the loop, but last I checked the app registers your phone number with the T-Mobile network so it knows where to forward calls/texts to. So it more than likely won't work for AT&T/Verizon. I believe Sprint has it now, but same method.

hi sorry, i left out a big important detail. I'm on t-mobile lol. so it would work for me. This is my first lg phone, and i've been on many other phones where we can easily cross flash carriers without the need of porting the roms. I was under the impression that the at&t model was slightly different? i should revisit that again just to be sure.
I was hoping if there was any hard evidence or experience that someone did flash an at&t rom without any hiccups. That'll mean we can do it vice versa.
Thanks for the info.
On other phones this has been possible, I would wait for a definite answer, or make sure you have a backup ready just in case you do try it...
I am on Verizon and I was also wondering if I can flash a T-mobile rom without the risk of an hard brick. I can take the risk of a SW brick.
Why would you want to do this
I'd be careful, there are probably significant differences, you can't use a vz phone on tmo network.

I'm pretty certain that all Vzw phones come unlocked and can be used on t-mobile. Might not get all the bands to work correctly, but will still work.
Vz runs a cdma network for voice and data, t-mobile runs gsm. Some phones can do both, eg Verizon's world phones, but by no means all of them. YMMV

If it is 4g it should be a "world" phone.
Here's the details: http://support.t-mobile.com/docs/DOC-6991
While the G3 isn't listed, the G2 is so I would assume it will work.
I have flashed a Verizon rom on my T-Mobile phone and almost everything worked fine. You'll need to adjust the apn and delete Bluetooth apn as it fc. The OP stated that he will most likely make a patch to fix the problems

I bought a note 4 on AT&T from eBay I was stupid and didn't read the advert properly my fault. Am wondering would I be able to flash my note 4 to UK unlocked rom at all? So basically it would work exactly the same as a note 4 bought hands free in uk. I have read there is difficulties in flashing international versions to work on AT&T due to network frequency but not much detail going the other way around
You can't flash anything on the AT&T version. It doesn't even have root at the moment and the bootloader is locked so you'll probably want to sell it.

If it's network unlocked it will work in the UK with your sim. Don't know if lte will work.
Yeah lte works and currently on ee phone works fine but just wondering if am able to flash it and install custom rom or original Samsung rom
I gurantee the AT&T Note 4 will NEVER see its bootloader unlocked. At this point in the game, it probably won't even see root.
I've read somewhere the android L will make it difficult for att to look bootloader and also android L will allow Uninstalling bloating software.

I read the opposite regarding the bootloader & rooting phones.
in terms of rooting which version should I purchase? I heard that the USA version has a locked bootloader which means it is not rootable correct? Is it impossible to unlock the bootloader unless Samsung does something or..? I would assume that since people are going so far as to refund their phones instead of waiting for an unlocker to be released if that is even possible.
I'm waiting to buy international version of phone with Xynos Chip and no AT&T bloatware. We will probably get better battery life and faster updates. We will lose HD and Wifi calling but no biggie IMHO.

Chance's of the USA version being Unlocked are slim to none... Even the Canadian version is locked down.

Having done development work in this field, I feel obligated to tell you that's not exactly true. Hd voice consists of two voice codecs - AMR Wideband, and AMR narrowband. These codecs do not explicitly require VoLTE to function. In fact, you can make "HD Voice" calls over 4G HSPA/HSPA+ using the narrowband version of the codec.

Sounds good to me. Here's AT&T definition of HD voice.

Yeah everyone dumbs down their definitions for the general public.
Basically, telephony in general has always had an 8khz spectrum width for audio. This was manly due to the fact it's small and low bandwidth. With the advent of 3.5g (hspa/hspa+ and lte) bandwidth is drastically increased. This allows for a doubled (16khz) spectrum width as there's plenty of bandwidth for it.

For AT&T and Verizon, correct. T-Mobile uses HD Voice over their 3G network, and you get better sounding calls when talking to another T-Mobile subscriber (I understand they will eventually bridge HD Voice to other carriers). VoLTE for T-Mobile (Advanced Calling for VZW) allows you to keep your LTE signal while on a call, as opposed to dropping down to 3G.

Good question. I heard a rumor that they did some sort of update and locked it?
I have the international variant and it does have VoLTE.

Singapore here. Singtel.
Would love to get international variant if it works with Tmobile.
I can purchase an international version on eBay, there is one currently for 789$ but there is only gold platinum available and the seller ships from NY.... i want to get this but unsure if it is a fake phone or something ><
The Phone may be region locked. Mine (South East Asia) came with a card that says, the Phone needs to be using SEA sim card for the first boot up.

I'm in the same boat, $789 seems lucrative, but no warranty so not sure should take that risk or not. I'm waiting for B&H to go on sale at least they provide their own 1 year warranty.
Does anyone know when the unlocked variant of Note 7 N930U will be available? I am just not buying a carrier branded one because of a lot of reasons...
I'm keeping close watch on this as well as I want to get the rom from it and install it on my TMO purchased Note 7. It's a good way to debloat and to get updates outside of when TMO says yes or no to them. I can't wait.
What reasons? If it's because of root, AT&T and Sprint variants have root.

I've had root on Android phones since the G1 but since the August patch to 6.0.1 it's just become to much of a pain in the ass to keep root and to have Android Pay. So the unlocked version of the rom doesn't come with a majority of Samsungs bloat ... it asks if you want to install the various apps during the first boot and you can say no. It doesn't come with the carrier bloat. These are the reasons. The only reason I've kept root on my Nexus 6P as long as I had was for greenify and with the Note 7 they've basically given that ability to the user without root. Folks have a lot of reasons to keep rooting ... I just don't. The OP might feel differently.
If you want the phone now, get the carrier Note 7 and then Odin flash the OS when Note 7 Unlocked is released.
For example, I bought the S7 Edge through AT&T but was able to Odin flash Unlocked software so phone is identical to unlocked version. I even got OTAs from Samsung directly. No root required and you can flash back to AT&T firmware and build if necessary.

Oh wow I didn't know that would work!? Is it because they are exactly identical? I remember that was not possible in the past with Samsung devices...
Yes, identical phones only difference is build and firmware. On AT&T, you lose VoLTe and HD Calling. On T Mobile, you still get wifi calling and VoLTE.
I Odin flashed my AT&T S7 Edge with no issues. No it is unlocked version.

This is great to know. thanks! Just a bit confusion, by "No it is unlocked version" do you mean that AT&T locked S7 edge converted to sim unlocked phone? Can use different carrier sim by flashing ROM of unlocked version?

Yes, S7 Edge converted to Sim unlocked US version with no carrier bloatware. Phone can be used with any US carrier. Basically, turning a AT&T S7 Edge into a non carrier phone.

Wow, I didn't know that. I was planning to sim-unlock TMobile locked Note 7 via some third party online service, but I guess I will now wait for the official ROM for SM-N930U and flash to SM-N930T. Thanks!
Update: Apparently this is not true. Some research helped me to understand that flashing ROM does not sim-unlock your device.
The Big IF being if Samsung releases a US unlocked version like they did with S7 and S7 Edge.

If there is a ROM for your region/carrier (or at least one that plays well with your carrier), you can try it to see if VoLTE works.
VoLTE is a little complicated and jumbled. Carriers seem to be deploying it in different ways. For instance on US AT&T, you pretty much need an AT&T based ROM for it to work, far as I know. And not all ROMs even have the option to turn on VoLTE.
Not a great answer, I know. But that as much as I can tell you.
thank you, actually i dont knw what's.. LTE is working but to make a call or to receive a call i need to keep Internet on, which leads to draining of battery faster. since my mobile supports VOLTE in at&t i though i can do something to on....

You can try flashing the AT&T stock rom backup in twrp. Even I'm using an AT&T M8 and I tried almost every custom ROM but each of them only shows the
volte icon in the status but it doesn't works. The only way is to flash AT&T STOCK ROM BACKUP if you're s-on ... If you're s-off then you can use the RUU.
