Hello, I recently came across a Note 3 tmobile variant online that is unlocked. I know that it is a dual band cell phone and I am looking to use it on my Sprint account. The person I acquired it from says that she used it on Verizon (even after a point when she would not benefit from lying). I am not completely new to flashing phones over from one CDMA carrier to another (prls, msls, mdns, NAM, programming, etc.), nor am I am new to rooting etc. However I am beyond lost when trying to go from TMo to Sprint on a dual band phone. Is this possible? How might I go about accomplishing this? Will I be locked into a specific rom? Any help will be greatly appreciated.
By dual-band, you mean CDMA and gsm?
You can't flash a Sprint ROM into a T-Mobile phone. and you can't convert an n900t to a CDMA.

Yes it has GSM and CDMA from everything I have seen online, additionally in the settings of the phone itself it also offers a choice in connectivity to GSM or CDMA.
I don't have the phone but are you sure it doesn't say wcdma in there n900t?

I am on ATT but I am tired of ATT BS and locked bootloaders and ROM work arounds. I want to be able to use international ROMs. Plus I want to have my ATT LTE.
I want freedom to have me device my way and with any carrier sim. With this said money is not the issue. So what do I buy. If I am reading things right the answer is a T-Mobile Version and then cancel the contract and put my ATT SIM in the Note 3.
Can anyone confirm or advise?
Want your cake (international version) and eat it too (non-international LTE) AND complain because getting both requires a bit of work? LOL
No carrier is going to let you have full freedom w/o you going behind their back (i.e. unlocking bootloaders and custom ROMs)

The T-Mobile appears to have an unlocked Bootloader and unlocked if paid in full. So that sounds like a clean unit to me. That I am free to load Intonational ROM's etc...
If you don't mind 32GB only of internal storage, which effectively translates into ~24GB of user available space - T-Mobile GN3 is your best bet. Pay in full, to get it unlocked and put your AT&T sim into it. Then you will have unlocked bootloader, no carrier network lock, no regional lock and it will work with AT&T LTE. You will be able to use international roms as well, as long as they're not for the octa-core version. You will also be able to flash AT&T modem to it, if you wish.
I just got the T-Mobile Note 3 from Negri (unlocked) It is $689 with no tax here in CA

I want to order a Note 3 from Negri to use it with AIO. I would like to have the unlocked bootloader but I'm worry about something I read in another thread here (Note 3 Carrier Selection):
"The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals."
What if ATT is using 1700 in my area for LTE? I will have the unlocked bootloader and no LTE? Where can I find what frequencies ATT is using in what areas? I made some searches without luck.
Any help will be appreciated.

Some search without luck? You've got to be kidding me! I have personally posted AT&T's LTE frequencies in at least 3 threads in Note 3 forums. It takes about 2 seconds to google a wiki page with LTE frequencies by carrier worldwide...FYI AT&T operates it's LTE network on both bands 4 and 17 in most areas. However, I don't understand why do you think there is a problem with AT&T & T-Mo using the same frequency in a certain area. There are 2 absolutely independent carriers, each with their own towers and your phone will get service from a carrier, based on whatever SIM you put in. What difference do these overlapping frequencies make to you?

I did find information about the frequencies used by each carrier. What I was looking for is what frequency is used in a given area, say near my house. Maybe that is not the right question since I'm new to all this problem.
In another thread (Note 3 Carrier Selection) people is recommending to buy the TMobile version over the ATT version even if you want to use it with ATT (AIO). Because the bootloader in TMo may be unlocked. But then cheols46 posted this:
The main difference between the 1700 band being used by AT&T or TMO device is that AT&T version will use that 1700 for LTE signals where as Tmobile variant will use the 1700 for their HSPA signals.
I have 2 HTC One from each carrier and while AT&T version will pick up LTE at my house with the AT&T sim card in it, while T-mobile version only picks up HSPA+ with the AT&T sim card. It really depends on the tower frequency you use in your area.

I want to know if that will happen to me if I buy the TMo version to use it with AIO.
Thanks in advance for any help you may provide.
That guy is getting only HSPA with AT&T SIM card because his APN for AT&T LTE is not configured correctly on the T-Mo phone. He probably didnt change the APN settings, or maybe T-Mo stock firmware doesnt even have those settings, since the network didnt support LTE when that phone was bought?
If your phone is configured correctly, and you use AT&T SIM you should get LTE service.

Will you advice to buy the sim unlocked TMo version instead of the ATT version, because of the unlocked bootloader and the support for TMo bands (again this is just something I read)? I'm planning to use it with AIO but after spending all that money it will be good to know that I could use it with TMo if I wanted.

If i were you I'd wait a week or two, until other people do it, and you can find enough feedback on how well things work. The question, you should be asking yourself is not a choice between T-Mo vs AT&T version, but T-Mo vs international LTE version with unlocked bootloader, because getting AT&T one with locked bootloader will severely cripple what you can do with your phone. Keep in mind if you have any LTE version with unlocked bootloader you should be able to flash AT&T modem onto it, once it becomes available, regardless of what LTE bands it currently supports.

I'm sort of forced to get an AT&T version (have unlimited data) but considering taking chance that someone will figure out N3 bootloader unlock for future versions of AT&T roms. Is that wise?

For some reason, I thought the salesman said both Verizon & ATT GN3's were gsm. Is that true or is VZ cdma? I thought I read somewhere they were switching over at some time. I was thinking gsm was preferable, but is it?
Thanks in advance.
The N3 is world phone so yes its gsm too
Sim unlocked ? I don't know the note 2 was unlocked but you can't add APN settings

Thanks very much. So I could use it at some future time on Straight Talk network? What about ATT after contract met? But would an ATT phone transfer to VZ if it's a world phone?

The ATT phones don't have the CDMA hardware to work on Verizon.

All verizon phones have CDMA radios in them. The 3G service from verizon is CDMA. International phones utilize a GSM 3G radio as well, as Europe uses GSM exclusively. The 4G radio, however, is GSM. Therefore, all 4G verizon phones are also GSM. Until 3G gets phased out, All Verizon 4G phones will have both GSM and CDMA radios.
When on download mode it says write protection enabled.....
its not letting me flash an AT&T or Tmobile modem either and I suspect that it is related to the write protection being enabled, Is it possible to disable said write protection? I've searched all over XDA and all I keep getting is some safestrap recovery nonsense
First of all. why are you trying to flash a ATT or T-mobile módem m

Write protection enabled has nothing to do with the bootloader being locked. It says that on every phone. The reason why it fails is those modems aren't compatible with our phone. If you are trying to use your phone on those networks you have to unlock your sim slot and change the apn.

the point is that I want to enable 4G on those frequencies.
If I'm not wrong they should be compatible but for they are being blocked off by software means?

Your wrong, the Sprint S4 does not have those LTE frequencies. You can only receive LTE on the frequencies that the Sprint S4 supports and it doesn't support the AT&T, Tmobile, or Verizon LTE frequencies. If you are going to use the Sprint S4 on those networks you will only get 3g, edge, or maybe HSPA+ if you have the right APNs installed. If you want to use LTE on those networks you should buy a phone for those networks.

i'm not looking towards using it on sprint, i'm looking towards activating at&t 4G for use on a at&t network or international 4G for use on an international
there shouldn't be a requirement for buying a new phone when the only main differences are software.

There are to many hardware differences to mention between the Sprint CDMA S4 and the GSM/international version. The main thing being is the SPH-L720 does not include the hardware to receive the LTE frequencies that AT&T uses and the rest of the world. Sprint never spend the money on extra hardware. In fact, the Sprint S4 isn't even compatible with half of Sprint's LTE network. It isn't a software problem, the hardware is not there. Be happy with 3g or buy an AT&T phone!

Basically Ive had the phone for over a month now and the connection issues have been constant. The carrier I use is Straight Talk. I got a new SIM card. Ive tried every APN setting it seems. And I cannot get any help. Did I plainly just mess up and by the wrong version of the phone I needed?

Should have gone for 9005.
When It is on GSM only mode I only get EDGE speed, and when I switch to either WCDMA/GSM or WDCMA only mode, I do get H+ but its not reliable and I frequently end up in emergency calls only mode and am frequently resending messages. What model should I get for the best results with Straight Talk does anyone know?

You need the N900A (AT&T) or the N900T (T-Mobile). GSM Mode means 2.5G (EDGE) only. WCDMA Mode means H+ (3G) only.
You can also try the N9005 if you're into tinkering and whatnot.
Your current phone most likely does not support the recommended 'fast' bands that are on US Carriers.

N9005 is most used internationally so more devs support this device. But the N900T also works too.
Not the N900A if you care about ROMs.

Okay then I'll pass on the N900A. Are there specific carrier branded N9005s? or are they all the same and unlocked. Sorry for all the questions. Also I barely figured out how to "thank" you >.<-

Yeah there are, and there are specific models of N9005 too with a different partition structure (Hong Kong 16GB)
You're going to have to find an N9005 not from Hong Kong just in case, even though they also sell the international 32gb version as well, and that is already unlocked SIM wise and region wise.
Also, if you come from the states, make sure the bands are supported by your phone. People have bought the n9005 from America to find the LTE bands don't work in Europe..

Discussion of this has been ongoing in the General forum. The assessment is, despite the implication that there's a GSM band in the Crystal's modem, there really isn't one, and it is impossible to use GSM on the device. Supposedly, the SoftBank model has GSM, but we can't exactly confirm that the Sprint and Boost variants are based on the exact same hardware.
http://www.softbank.jp/en/mobile/product/smartphone/aquos-crystal/ The SoftBank site says it can do international GSM as a world phone, but tests say Sprint and Boost can't. It's not exactly confirmed what's going on.
The device is set up with VoLTE, so assuming the carrier has VoLTE on their 4G signal, a GSM carrier would work just fine, but we haven't seen any luck with it yet. Software block is an assumption right now, so maybe when the bootloader is unlocked, but that's still a ways away. We've not even achieved full root yet.
