[Q] 4G/LTE bands permanent? - Galaxy Tab S Q&A, Help & Troubleshooting

Hello all,
I am thinking about picking up a Galaxy tab S 8.4 (T705), to use as a new phone. I noticed that is doesnt support the LTE bands for US AT&T. While doing my research, I found it mentioned that the T705 was coming to AT&T sometime. http://about.att.com/story/att_among_the_first_to_bring_samsung_galaxy_tab_s_with_lte_to_the_us.html
Seem to remember back in the old days (Geez, I sound like an old timer), on the old HTC TYTN's, that we used to be able to flash a radio, to pick up different bands. Its possible I am incorrect, it has been some years.
Was curious, does anyone know if I picked up a T705 with unsupported bands, would I be able to flash the device to get the correct ones at a later date? I suppose I would have to hope someone did release it, but just wasnt sure if the bands were permanent with these new devices, or not.
Thanks.

Will I be able to use this phone in Asia?

I know Sammy had to make this model because of some hardware compatability issues with T-Mobile's 3G network, and I've head that the standard international S2 (i9100) won't work with T-Mobile's 3G. If I buy the T-Mobile version, will I be able to use this in Asia? (specifically Thailand).
Right now I'm debating whether to get this or the Sensation. I'd rather get this phone, but I'm moving to Thailand next year, so I just want to make sure everything will work. I've searched everywhere and I haven't found an answer to this question.
it will depend which network frequency you are planing to use it on, but the answer is likely yes

Unlocking all LTE bands on my Verizon Note 4

Hey,
I just ported over to Cricket Wireless because Verizon was just taking way to many hacks at my wallet. I've ran into a few snags I was hoping I could get some help with.
1. Every time I boot up my phone, it says I don't have a Verizon SIM card. Yep, I get that...I'm not on Verizon any more. Is there a way to make the phone understand that?
2. As I understand it, Verizon LTE phones only use 2 bands, while GSM phones use 4 bands...or something like that. Is there a way to unlock the other bands on my Verizon phone? It seems like they would be there, but locked out, right?
3. I tried to search for a firmware update, but encountered an error. I was expecting this. When android "M" does come out for my phone, how am I going to do the update?
4. Now that I'm not on Verizon, is it possible to flash ROM's?
Thank you for any help you can give me, folks.

I can't exactly answer questions 1 and 2, however,
3. When Android 6.0.1 comes out for the Note 4 SM-N910V, you will have to flash with odin when a tar comes out as you are not able to use OTA unless you have a Verizon SIM in the phone. If you still have your old Verizon SIM, you can use that, update, and then switch back to your new SIM if you'd like.
4. Unfortunately, no. Your phone still runs Verizon software and relies on it. So if and when any root method or bootloader unlock method comes out you will need to use the method for the N910V.

For question 2 try downloading 4G LTE Switch on the play store. Try changing your preferred network type but test texting and calling to make sure it works correctly. If that doesn't work I'm pretty sure I heard people bring the phone to Verizon to get it "unlocked" to use overseas. Not 100% positive about that though.
HI Hope this helps.
You will need to root device to access service menu, from service menu you can activate locked out bands.
You can use temp root with Kingroot this will allow you to access the locked out service mode on the device. Once in service mode you should be able to activate locked out bands.

Best of luck
Any Luck on this thread?

TMO band unlock

So I saw this thread for the S5 (http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059) that's says it's possible to unlock a bunch of bands that will make it work better on other carriers.
My question is: is this possible to do on the Verizon Note 4 running CM13? I switched to T-Mobile and am only getting EDGE in an LTE area. Since it happens on another Note 4 on CM13 and an iPhone 5, I was thinking it's because this phone only works with Band 4, while TMO might use the other bands where I am.
If that guide will work, I'd love to follow it and at least get LTE working on some of our phones (whole family moving to TMO), but I want to make sure I might actually be able to do this, so I don't break my phone.
Edit:
Should I trust this guide (http://dorylabs.com/how-to-install-different-modems-radio-baseband-on-galaxy-note-4/) and flash the ROM modem?
I second that ??

Sprint version same hardware as unlocked?

Hi all,
I've been trying to find more information on this but surprisingly I don't think anyone has actually asked.
What I would like to know is, does the Sprint version have the same hardware to support the same LTE bands? (And 3G)
I know that this device can be unlocked to be used on a GSM network via some of the methods here on XDA, although I'm not too sure if it's going to have full network support like the unlocked one.
Thanks!

Verizon Note 8 on AT&T - Current Status?

Dear Friends,
Hope everyone is well. As a side effect of having wealth of knowledge, reading through the forums here I believe the answer to my question is still, "yes" however, I would still like to confirm and make sure:
If I buy a Verizon Note 8 today, whether it's from Ebay, Swappa, Craigslist and etc and whether the user did or did NOT update to the latest Bootloader version and firmware version (Oreo)... Is it still possible to use some combination of firmware, Bootloader, CSC and etc to convert the Verizon Note to an AT&T Note or the unbranded US Note 8 and still have unrestricted, full functionality on AT&T?
If, yes, indeed, can you please point me to the right guide and files so that I can go through my purchase?
Appreciate your help in advance!
Any input, friends? Trying to buy a Note 8 based on your expert opinions ?... Thanks!
I converted my VZW note 8 to AT&T and used it flawlessly for a few months. This was before Oreo was released. I've since switched it back to VZW.
While on AT&T, volte & wifi calling worked as well.

It is always best to get the carrier brand you intend to be on....
But if you can't pass on a deal, yes you can follow switching carrier guide to turn a Verizon Note into an ATT Note....
On the one hand if you need to move between carriers or around the world, it be better to get the Verizon phone even for the AT&T network because it gives you CDMA + Quad-Band GSM. If you are going to stick with one carrier, if you get a newer phone, it will probably support 100% of their current and soon-to-be bands while the Verizon might only support 90%. That might make a difference in aggregation. Depending on the company, they might not allow you to use aggregation or VOLTE or Wi-Fi calling without their branded phone, although ajent above has had luck with at least 2 out of 3 of those by using a Verizon phone on an AT&T network.
