Just wondering if anyone is aware of a way to unlock the “Sprint Spark” LTE frequencies for this phone — and maybe some T-Mobile frequencies as well for expanded network coverage.
Anyone aware of a way to force VoLTE as well? I see it for OnePlus phones but not this.
At this point, I don't think any of that is possible. As you may know, there is no sim card slot on the sprint s3, and I don't believe the meid in the phone is capable of VOLTE, or even TNA. There is no way to switch to the T-Mobile network with this phone, and even if there was, it's not "certified" to use VOLTE on the network.
However, now that I'm thinking about it, if you have Odin, you may be able to flash the d2refreshspr stock rom, which I think has those bands. Also, if you have a custom recovery, you might get more bands from roms labeled "d2lte" which is a unified rom for all us snapdragon s3s.

okay so my problem is that I switched to Metro from Verizon with my htc one I've seen posts back from September but not anything recent, now I'm wondering whether or not anybody's figured out if it was possible flash a radio from metro or T Mobile and get the data working with at least 3G on this phone. also I know there has been some type of debate on whether it's a hardware or software issue preventing us from actually doing something like this but I have read that all of the bands are available but Verizon operates on 750 and Metro operates on 1900 right but they said the both LTE bands are in the phone?
so essentially I asked for the tmobile bands because T Mobile & Metro merged so my base assumption is the metro and tmobile have the same bands now and then if I have the tmobile bands then I would be able to operate Metro just fine. please do correct me if I'm wrong.
If possible would I need s off?
It's never wise to flash a radio that isn't designed to be flashed on a phone.
Have you set the phone to global and put the metro SIM card in and see what happens?

yes I have talk/text but it turns my data off when I call somebody but I'm just looking how to get higher than edge at least on this phone because I want unlimited data because I travel a lot and I don't want to have to continuously pay for data throughout the month which Verizon screws you on basically
From what I've seen out of the public FCC filings, the Verizon M7's hardware was redesigned specifically for Verizon's network with a few GSM bands thrown in for basic roaming support. It physically lacks the 3G and 4G radio components to work on T-Mobile frequencies. So no matter what kind of firmware you flash, it's not gonna work for anything beyond 2G and all you might end up doing is bricking the phone. You'll have to buy a T-Mobile or international model if you want full band support.
I'm looking to bring an unlocked AT&T Note 5 over to use on VZ.
Is it possible to flash VZ firmware and have the phone work just as if it was a VZ to begin with (and receive 3g data, text, and calls) or is that something that's hardware related and flashing the new firmware won't help?
I've found this information, so I know the consequences of using an AT&T phone on VZ normally...
"If you're hoping to use your unlocked AT&T phone on T-Mobile, you should have no problems. Both carriers run their networks on GSM technology, so once your phone is unlocked, just pop in your new T-Mobile SIM card and you'll be up and running. AT&T and T-Mobile both use Band 4 for their LTE service, so 4G LTE devices should be able to access the network without issue.
Although Verizon uses the CDMA standard and not GSM, you still may be able to use your AT&T 4G LTE device on Verizon's LTE network, as they both run on the same spectrum; so LTE data should, theoretically, work fine. However, it's unlikely that you will be able to make or receive calls and texts, or access data over Verizon's 3G service.
Sprint is also a CDMA carrier, but runs its LTE network on a different band of spectrum than T-Mobile, AT&T and Verizon; it may accept selected AT&T devices on its plans, but you'll need to check first."
I'm curious, because I rooted an flashed the unlocked software on a friends VZ's s7 for use on Republic wireless, so I know this sort of thing can be done. I'm just not knowledgeable about the differences in these 2 scenarios.
Thanks so much in advance!
You can't flash any firmware on the AT&T note 5 other than official AT&T note 5 firmware because the bootloader is locked. I'm not sure about the part of using this Note 5 on Verizon.

Before i explain what i/we all hope to achieve, ive been increasingly worried about network shutdowns. Ive seen at&t shut their 2G network down, I believe verizon is next with sprint or t-mobile to follow. For those who dont know without VoLTE, us verizon users use 1xRTT which is 2G voice. So, if verizon shuts the 2G network down, what do we do? So now that that speech is over.
Ive seen threads around on other phones and somehow the devs for these phones got VoLTE working on united states carriers. i dont know very much but i hope we all can use this thread to gather info and come up with ideas to get it working. I do know that the stock software has some sort of "sign" that in some way shape or form verifies the phone in some way.
The unlocked one supports many 4G VoLTE bands. If you want to know your carrier supports or not, ask your carrier customer support for VoLTE bands and cross check with below link.

Useful info, but I believe our main issue with custom roms is some sort of signature that tells the carrier something, thats about all I know
Hi,
If I take a AT&T S9, Unlock the bootloader (if possible), root it, and flash a custom rom on it will I then be able to use it on Verizon?
Thank you in Advance.

ATz&T is GSM Verizon is CDMA incompatible
Perhaps @sw1173 is a dinosaur or a forum troll?
Verizon 4G LTE is not CDMA. It's 4G LTE and fully compatible with 4G LTE used by other carriers around the globe. Verizon 2g and 3g is CDMA, and only still exists to support older cellular data and IoT devices and some dinosaurs using ancients relics for devices. Verizon announced they were planning on completely shutting down their CDMA network the end of 2019, but just recently decided to postpone the shutdown for up to another year. Verizon has been permitting activation of an ever expanding list of unlocked phones for some time now, including devices like the OnePlus 6T that has no CDMA support, just 4G LTE. If you already have a 4G LTE device activated, you can swap the SIM into another 4G LTE device and as long as it has radio band support for Verizon's spectrum (use frequencycheck.com) as well as software support for Verizon's VoLTE settings, you're good to go. They don't seem to have a VoLTE whitelist like AT&T.
Sadly, the bootloader on the US Snapdragon S9 can not be unlocked at this point (no hacks) like the foreign SM-G960F(D)/965F(D) (Exynos with unlocked bootloader) or the SM-G9600/9650 (Snapdragon with unlocked bootloader) in order to install custom ROMs. I suggest everyone avoid US Samsung phones, period, because of this, and be sure to share your discontent with Samsung. Personally, if I were you, I would get the SM-G9600 or SM-G9650 (China / Latin America Version), root it (easy), and flash the files here to get Verizon support:

If you buy or have a carrier unlocked US S9, including from AT&T, you can use it with any US carrier, including Verizon. You'll probably want to flash the Verizon firmware on it to get Verizon features including WiFi calling though:

Presently you can't unlock the boot loader on the n960u therefore you can't flash Verizon's firmware. Call Verizon and you will be told they are CDMA and are not changing but are adding capability for 5G after 1/1/2020, which will allow the use of various GSM devices to use their CDMA network.. I just spoke with Verizon sales and their technical support.

incorrect, this has been incorrect since the S8 when Sammy decided to not make different models for the US market. All S9's built for the US market are physically identical

in addition to this correct information, id like to add that phones can be debranded by flashing the U1 firmware, but will require a modded Odin in order to get around the write protections put in place meant to stop us from doing that

incorrect. Well, youre right in saying that it cant currently be unlocked or rooted, but you CAN flash verizons firmware. Verizon hasnt been a cdma carrier strictly speaking for a decade. LTE has always been GSM, and ever since vzw jumped on board, theyve been a hybrid at best. On top of that, with VoLTE becoming more and more popular, their cdma transceivers have been getting less and less usage every day. 5G isnt going to be the splash a lot of folks think it will either. New handsets to support a new communication method that just isnt needed in most places. And finally, most handsets produced in the last few years are hybrids, especially those sold in several countries. The biggest exception to that rule is the chinese phones that dont even have cdma radios in them.
Just got the G960U here in USA and its great.
But that fact that its my first bootloader locked Samsung is bugging me and im pretty sure i'll return it.
I use UltraMobile mvno -T-mobile sim with Wifi calling enabled.
Both the bootloaders on these models are unlocked correct? They are both Exynos? If there another model that has unlocked bootloader?
Is one more desirable than the other?
Any major drawbacks/differences with these models if i were to use in USA?
for example, do devs create more custom roms for one or the other?
Or would one model be more likely to be able to get wifi calling better like if i flashed the right CSC?
Thanks
Hey I'm thinking about buying a G960FD as well for use in the US. I have G930FD's and G950FD's currently. The F models don't have LTE bands 30 (AT&T) or 71 (T-Mobile) - frequencycheck.com is a great site to look up phone/carrier compatibility. The lack of these frequencies in the radio is not a deal breaker because these are just for extra capacity at this point, though band 71 with T-Mobile offers additional outdoor range being low frequency. You will need to root to in order to get VoLTE in the US, and this will be necessary for T-Mobile since T-Mobile only has 4G coverage and some crappy 2G coverage outside of large cities. So without 3G coverage calls WILL fail outside of large cities if you don't root to enable VoLTE since the phone will not be able to place a call on 4G LTE bands without VoLTE. AT&T doesn't typically allow non AT&T unlocked phone IMEI's to use VoLTE, and AT&T will be shutting down 3g in a few years. At that point, their IMEI whitelisting may go away and they'll start allowing an phone to use VoLTE, otherwise they'll start losing customers. If they don't change their attitude though, your phone will also not work on AT&T in a couple years (they don't have 2G enabled anywhere anymore). Verizon is also shutting down their 3G network in a couple of years.
I actually came searching XDA to see if anyone had a SM-G960F or SM-G965F working with VoLTE (and specifically dual VoLTE on the FD since it's supported) on any US carriers. I haven't come across anyone yet. On the Exynos S7 and S8, if you don't need WiFI calling, it's actually pretty easy to get VoLTE working without having to install an bunch of crap. There's just 4 files you need to edit or overwrite in /system/csc and one additional VoLTE settings file you have to place there as well. I'm thinking it would be the same with the Exynos S9. I just need someone with an S9 to confirm. Since you need WiFi calling, it's going to be a bit more work. You can look at the CSC selection tool easily found by searching here on XDA for the Exynos S7/S8 to see what you'll need to get WiFi calling to work (it's not that bad to go through the code and files in the zip installer). You may end up having to extract the US Qualcomm S9 T-Mobile firmware to get the required files out of it, or you might even be able to get away with simply flashing edited portions of the S8 CSC selection tool files to your G960F to get VoLTE and T-Mobile WiFi calling to work. (If you flash the CSC selection tool to directly to the stock ROM, it will break a lot of things due to the permissions XML file). I would plan on spending a few weekends to get VoLTE and WiFi calling working on it though.
If anyone has any additional experience, please chime in here!!
Also, one thing to pay attention to whenever you flash stock firmware using ODIN is Samsung's stupid e-fuses that prevent you from downgrading to a different bootloader level which will lock you out of downgrading stock firmware. It's the first number in the firmware descriptor. For example, if you blindly flash a U3 or S3 firmware, you can NEVER go back to a U2 or S2 firmware outside of a custom ROM. And even with a custom ROM, you may end up with compatibility issues with the new bootloader.
Another thing is when you root Samsung phones, it trips another permanent e-fuse that not only voids your warranty, but prevents apps like Knox and Samsung Pay from working ever again on the device.
To answer your questions:
The FD is just dual SIM - no other advantages. There's actually a hack for the Exynos S7's that will convert them to dual SIM since it's the same hardware. I'm not sure if it's like that with the Exynos S9.
Yes, the Exynos international versions have an unlocked bootloader (just have to go to enable developer options in the OS then go into developer options and enable OEM unlocking)
Yes, having an unlocked bootloader means there will be MUCH more custom ROMS and development out there.
It looks like the SM-G9600 or SM-G9650 (Chinese/Latin American) are the versions to get. They have the Qualcomm Snapdragon 845 processor, is bootloader unlocked, and apparently even working on Verizon and T-Mobile (see the thread below). They don't have bands 30 or 71, but that's not the end of the world since most older phones as of a few years ago don't have those bands. I'm still wondering if dual VoLTE is working on these.
