I have a N910S and I would like it to to have all of the AT&T bands. Is there a way I can flash the AT&T modem to my 910S or do I need to change out the Radio in order to Receive all of the American Bands on this Korean phone? Or do I just need to use a custom rom? Any light on this situation will be helpful.

HI, really sorry if this is a noob question but would someone be able to answer this asap. I live in the UK and purchased an S5 off ebay it stated it was the SM-G900F (UK varient I believe) but upon delivery I checked and its the SM-G900S which is the Korean vairent.
So I put my sim in and it displays that im roaming which is obviously wrong. Can I just flash a UK rom and will everything work like uk varient or is the radio bands or anything else different. Please answer asap as I will need to contact ebay.
Also is this 4G version and will it work in UK?

Here are the specs http://pdadb.net/index.php?m=specs&id=5448&c=samsung_sm-g900s_galaxy_s5_lte-a_samsung_pacific and here http://www.droidgod.com/2014/05/samsung-galaxy-s5-sm-g900s-full-specifications-features/. It looks quite similar for the G900F but check if the supportd LTE bands are compatible.

No, LTE bands are defined in the radio chip. You cannot change these bands by flash a different rom or modem.

Yes, as the cpu/gpu, screen and reoslution are similar i guess you could do that. Don`t know the supported LTE bands of the 900S though. Maybe its best to file a complaint to Ebay about the seller misleading you as you probably will not have warranty either.
I will travel to the US shortly and want to buy an S5 to bring it back with me on my way home (Mexico). I think both the AT&T 'A' and the international 'M' version should cover my frequency needs ('M' has an extra band), but I would like to get some insight on which one might be a better choice in terms of Rom development and official updates (pushed out sooner). Thanks in advance to everyone.
AT&T have a locked bootloader so you can only use AT&T branded firmwares on a 900A.......
If you find yourself in an area/country that uses a different radio/modem band to AT&T, this could be a problem........

Thank you so much. Mexico (on my carrier) uses the same bands as in AT&T but seems like the international 'M' version might be a better choice isn't it?

I would say probably so.......
I believe the AT&T's locked bootloader makes it harder to root as well, and because only carrier specific OS can be loaded, I'm sure that's had an effect on the custom rom development for the device too......
I personally would choose a device with as few restrictions as possible.....

Hey!
From what I've read online it looks like all S7 Edges are built identically which means that the bands must be controlled by software. Are there any firmwares, patches, or tricks that enable other bands? I have a Verizon S7 Edge on T-Mobile so I'm mainly looking to unlock band 12. I saw this post: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but im not sure if that will unlock the bands or not. VoLTE and WiFi-Calling would be a plus.
Thanks.
So you mean like flashing the u firmware or something

I believe that is what this post describes: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but I dont know if that will actually unlock the bands or not. Have you tried it? Will it actually unlock the bands?
Thanks.
I haven't tried this but my s6 edge works for my gf on metro and it's a Verizon phone with of1 firmware. I don't see why the u firmware wouldn't work for you.
Flashed the U Firmware. It didnt unlock the bands. Any other suggestions?

Maybe now that you're on the U firmware you could flash the T-Mobile firmware? Not sure if it would work or not, maybe you'd be willing to try. Make a backup just in case...
I do belive the band's are controlled by the baseband/radio file in the updates, of course most of my experience is with the ENG bootloader on HTC devices so I think for Samsung it's either modem or pda....more experienced members can correct me if I'm wrong, so feel free to jump in

Do you think flashing the T-Mobile firmware would help? I posted in the other thread asking if it would work but if flashing firmeware replaces everything (bootloader, os, kernel, etc) then it should work right?
hi, i gave someone verizon s7 edge usa version to use in Canada, permanently, and that person can do pretty much everything BUT receive sms. Any ideas?
thanks!

Check APN settings. If any thing else try having them flash U firmware and see if that helps
i believe proper apn is there, as for U firmware, is that firmware that comes on Unlocked phones?
thanks !

Yes it is. Just note, if they need to flash back for any reason they need to make sure to check re partition in odin or it will not flash back to Verizon firmware.
I've been searching and can't find a definitive way of flashing TMobile firmware to the unlocked s8.

I assume you have US Unlocked S8....
Normally you don't need to flash it with T-Mobile firmware because most of features are supported such as: VoLTE, Band 12 and WiFi Calling. If you do decide to flash here is the tread: https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817
Yes US unlocked. The TMobile radios are better and utilize the new tech that TMobile uses. I'm assuming I can use just the radios, but there aren't any definite answers.
I am trying to get figure out the same answer.
I also have the G950U1 and would like to flash the T-Mobile firmware to obtain the 256qam and 4x4 radio.
I'm still searching for an answer.
There is also T-Mobile firmware that doesn't have bloatware, but I don't know if it is missing any feature that you guys are looking for. I do have an unlocked S8, but haven't flashed it yet.
I've attempted using both Odin, and the modified PriceComsy Odin to flash the T-Mobile G950u firmware onto the Unlocked G950U1, and it results in FAIL! (DeviceInfo).
Ended up just flashing the modem. Just need to see how this thing works now
In case anyone wanted to know how the T-Mobile modems work on the unlocked variant, I'd say quite well with all TMobile features working

But what kind of speeds did you have before that?
I am going to go off the limb and suggest that flashing the 950u T-Mobile Firmware doesn't give us the 4x4 MiMo Radio and 256QAM. I've not seen a difference in call quality, data speed, or signal strength. Can anyone let the community know what the three TMB/TMB/XAA mean?
This should be a big decision differentiator when selecting between the S8 unlocked and S8 T-Mobile branded device on the T-Mobile network.

The fastest speed that is in the screen shot, half of that. Also I've noticed I don't get random lte to H drops anymore where I normally would in weak TMobile areas.
