[Q] Models other than N900T for T-mo WIFI call

have a "note classic" that I love. thinking I will also pickup a Note 3. Will any of the other variants of this model [AT&T for instance] work fine with a T-mobile ROM? on my current note, the i717 model and this one are pretty much interchangeable ROM-wise.
I am a HUGE daily user of the WIFI calling app on T-mo net. excellent feature

All Tmobile branded phones which have a Tmobile sim card and have a stock
or stock based custom rom/firmware have wifi calling.
Any and all models of phones which are not Tmobile branded will not have
wifi calling and are not compatible with wifi calling even if the phone is
unlocked and or rooted.
Good luck!

understood, but that is only stating the obvious. my question is whether other variants of this same platform are shown to be compatible with the t-mo rom, modified or stock [mine is modified, for instance]. with note-1 and others the answer is yes - some are, others are not. the t-mo rom and modem can be applied to i717 in the example I gave.
wondering if there are any such friendly models of Note 3 other than the default N900T

I think I understand what you're saying. The short answer would be no. I dont think you can flash modems from other models interchangeably with the note 3. I could be wrong though. So don't take my word for it 100%. But im pretty sure that the modems are model specific and flashing a modem from a different model note 3 could end in a brick.

Yea, just stick to flashing our own modems, usually the newer ones for the note 3 seem to be better in my experience, with the s3 that was different but yea don't flash other carriers modems.

9005 ROMs are compatible with tmob, but their modems and the firmware base isn't. You would not want to flash a 9005 based firmware modem boot loader on our smn900t. Bad idea. That said, their ROMs, are compatible, some mods etc etc.

What I was trying to say is that variants can be ported and
they do work fine if you keep your modem/bootloader BUT......
Here is what I was saying about WIFI Calling, even though the variants
work, they cannot and will never have a WORKING WIFI-Calling and
that's what the OP was asking about.

Sure, you are correct, I was responding to the individual posts, i don't believe I quoted the ops original question, although this is true, I was just elaborating upon some comments that I felt compelled to answer.

Working Wifi calling will never happen if using a ported rom.

There will be F400 (Korean model) and D855 the international one. Plus other variants China, Japan etc So I think it will have to be separate. Or otherwise we might be able to flash int'l roms. hardware will be the same. Chipset, screen, modem even for some korean version.
Time will tell. I think it will be like this first development on the F400 then later more on the Intl G3 once its out in 3-4 weeks time.
Good you tube vid on the Korean model Pros and Cons I for one could not wait so imported.

[Q] Which variant of G3 should I buy on T-Mobile

Before you reply sarcastically and imply that I should obviously buy the T-Mobile variant, I was curious because the international G3 seems to have double the amount of ROMs than the T-Mobile (D851). Correct me if I am wrong with this assumption. Only problem is that people tell me that the international variant doesn't support the same bands as T-Mobile LTE has. Is this still true, or does the international G3 now work on T-Mobile's LTE network? My end goal is to have a good amount of ROMs and best T-Mobile LTE support, so is there a way to flash international G3 ROMs on the T-Mobile variant by reflashing the bootloader and radio or would that still lead to a brick? Thanks for reading

I have the T-Mobile D851 G3 and before LP came out for the international models, I was able to flash their stock KK Roms with no problems. I ran version 1.2 of Cloudy Rom for quite awhile and that was a great Rom and very stable. I didn't have to flash any kind of bootloaders or anything to run the Rom.
It is true that development for the D851 is kind of slow compared to the international ones but there are still great developers for us. Skydragon is a great modified stock Rom and we do have some choices for some AOSP LP Roms too that are updated pretty regularly. I've ran a few of them and they run great. But I'm a stock kind of guy so I always revert back to Skydragon.

I have the D855 32GB using T-MOBILE . And no LTE only H+ getting around 4 Mpbs to 14.4 Mbps. I'm on their MVNO Ultra Mobile pre-paid limited data plan so its ok for me. Love the D855 cos its unlocked and already on CloudyG3 LOLLIPOP. Only paid $19 a month unlimited talk, text and International talk certain countries. But 100 MB data. Well if i need more data i just top up $5 for 500MB. I always on WiFi anyway.

Oh, did you flash the Cloudy ROM that was made for the international D855 or made for the T-Mobile D851?

Hmm, since I'm in an area where it is easy to get LTE, I would prefer a model that ensures LTE. But thanks for your input!

This is the version of Cloudy that I used that is still KK since we can't use a stock LP Rom on our phones yet. This one was for 850/851/855/LS990/VS985

asop custom roms? and custom roms on verizon?

I understand the device works on Verizon but am curious if all custom roms will support the bands verizon requires? I am guessing that the modem is complete (works through and through) for all bands but not sure so am wondering if separate roms will need to be created for the network (really theirs only one, verizon) that uses different bands. I would love this device running Liquid Smooth or similar on verizon!

This shouldn't end up being the case as custom ROM's will use the Nexus binaries provided by Google available to developers which will support all of Verizon's band so no need for a Verizon specific RIL implementation for example. As a result you will be fine to run AOSP based ROM's such as Liquid Smooth. The thing for ROM's will be more about whether you have the American model of the device or the International model. Let me me know if you still have questions!

Thank you. Which model do you suggest for putting custom ROMS on?

If your going to use it on Verizon, I would recommend going with the North American model which is model number LG-H790 for US carriers. Both models will have a great selection of custom ROM's and goodies, and with only minor differences between the two models the hard working developers won't need to do to much extra to support both.

Unlocked US SM-975U1 or Unlocked Dual SIM SM-975F/DS : Best phone over all

I have the choice between Unlocked US SD SM-975U1 or Unlocked Exynos Dual SIM SM-975F/DS to be use in the US with T-Mobile.
I want the best overall experience.
Which one will you go with?
Thanks

Do you want to root? If so choose the Exynos model.

Is there a performance difference between the Exynos and Snapdragon?
How would it work in the T-Mobile network? Any idea?
Are software updates received even if tje product is not a US model?
I appreciate the help
Thanks

Well yeah the Snapdragon is the superior model but can't be rooted.
I have the US unlocked version and all I did was pop my sim in and it works great.
I believe with non US model you have to flash the firmware to it to get them to work on US carriers.
It's really up to if you want root or not.

The N975F/DS will work fine on T-mobile. Took my N910F to US when I moved from EU to US, no problems identified as TMO uses GSM network (non cdma).
Be aware that you cannot flash US (TMO) firmware to N975F/DS.

the biggest issue is that you miss one of out 4 (ATT) or 5 (TMOB) bands. sometimes you may get very slow data

Thanks everyone
