Well I have 2 unopened Samsung Alphas sitting in front of me.
1. SM-G850F (International from Germany)
2. SM-G850M (Unknown Origin)
I have Many sim cards that i am using. But the main one i want to use is the T-mobile USA.
What i have gathered reading is the F has the custom recovery where as the rest A,W(QuadCore) Y(Asia ?) do not.
All of them seem to have Root.
Version A is tuned for AT&T
Version W is tuned for T-Mobile USA LTE (But is a Quad)
etc etc
But the info on the M Bands is very vague, as in the Band listing on the website is always different listed for the M.
So what are my advantage of picking one over the other (M of F) for T-Mobile USA ?
As far as i know every other version than the A has exynos chipset with the octa core cpu and the A has qualcomm with quad core cpu and thats why almost every other version has root and the A dont.
Sent from my SM-G850F
Why the hell are they doing this ...
So how different is the M from F ?
I cant find any info regarding the M having custom recovery also.

Well i just took a bite xD
SM-G850M on Tmobile USA
I have 4G Stable aka LTE
Very happy with my outdated discontinued phone hahahahahah
I agree the Bands Info on 850 M is vague or conflicting .
But it seems that you should have the
1700/ 2100 LTE Bands for Tmobile 4G LTE and the 1900 band for 3G
needed with the M Version.
Are you getting full performance on 3G , 4 G and LTE on your Alpha ? ?
Yes i am getting all bands 2g 3g 4g H+ LTE depending where i am at sometimes E. Though during a call i only get lte or h if non of those my data doeent work during a call
SM-G850M (Vodafone) = Branded
SM-G850F (Europe) = Non Branded

Can you tell me if the G850M is carrier-branded in any way? I know the G850F isn't, and I was wondering if the same is true for the G850M. Basically, I would like to receive Android updates directly from Samsung without carriers getting in the way, and I would like free use of the Portable WiFi Hotspot/Tethering feature (even without having it as part of your plan). I know Nexus phones allow you to do this.
Thanks!

850M is not carrier-branded...it's unlocked and sold by Vodafone. I rooted mine, so can't get updates through Samsung anymore.
I did use it to create a Wi-Fi hotspot to tether my laptop. It works well, and I do not pay extra for this feature on ATT.

Thanks very much for your responses! I greatly appreciate it.
I found a 850M on eBay for $89.99 couldn't believe it, excellent condition like new. I rooted it, installed another XDA members 4.4.4 ROM but couldn't notice any difference from stock, works fine on Cricket (At&t) prepaid, 4G same speeds as my previous S5 Mini At&t version phone, around 8mbps down, 4mbps up, half that when on a call. I cannot find many 850M's on the market, it's amazing. I want to buy at least 1-2 more, these are one of the best phones Samsung produced, especially one of the last good phones with removable battery! There are more 850F's on eBay but may not have as fast data with At&t as they are EU version. After my experience with S5 mini on 5.1.1 ROM I noticed much faster battery drain and prefer 4.4.4 performance. Hope my post helps someone=) -Aje

Here is the link to the ROM.
http://forum.xda-developers.com/gal...m-rom-lukrangelo-v1-brazil-zto-4-4-4-t3116098
However I didn't notice any difference from the stock ROM, was surprised to see the same original games included which I consider bloatware. Anyway the phone works great after rooting and uninstalling a lot of things, although it did suddenly crash and restart yesterday while on a phone call, first and only time in about a week I've had it. I love this phone and the size is perfect.
Really wanted to try this ROM but DL link is no longer working and no one is replying lately.

CM for 850F works on other 850?
Probably not as they have different radio's and frequencies, I wouldn't try it. Still trying to get someone to share the slim rom for 850M.

I popped my cell sim into the tablet. it connected at H+. I guess I answered my own question.
Thanks
I bought a Rogers tablet off a guy who said it was a 3G model. The box was opened but the tablet is brand new.
The Box says 4g on in. I've already put overcome on it. now I'm wondering is it a 3g or a 4g.
Is there anyway to tell by the physical case?
Also is there a thread on the different models and sub model numbers.
Thanks

AT&T markets HSPA+ as "4G." Rogers does the same thing. So it's officially a 3G Tab capable of 21MB down on a HSPA+ network. Rogers and AT&T call that 4G the rest of the world calls it 3G or 3G+. I'm using a phone SIM in my 3G UK Tab on AT&T and get 8MB down in fake-4G (the only real 4G is LTE) cities. The benefit of using a calling plan vs. data-only is you get unlimited messaging too. I don't know if Rogers works the same way.

good explanation and yes Rogers does work pretty much the same way.
The only differnce will come is with the roll out of LTE that is ongoing for Rogers. It is my understanding the 9500R just released by Rogers is capable of LTE but your sim card will have to be changed to accomodate both the increase in speed and (more importantly) the increase in billing charge from Rogers.
so is the latest overcome the best rom to use? or are there others that are better?

there are the stock roms just issued with KI2 base but I believe that is also the basis for Overcome -- install of which also provides root and a complimentary CWM file. The simpicity of this appealed to me!
So its the best starting point I would say at this juncture.
BUT the stock roms for the 10.1 are themselves quite robust, something those of us with the Galaxy S for example are unused to! So you can root and install cwm without overcome and use a stock rom -- best is always subjective and a personal judgement.
Some of the other Roms have good development but are for the wifi only version and look good but aren't meant for the Rogers Tab -- didn't stop me trying them and checking them out mind, but it all depends how much of a flashaholic you are! You need a deodexed rom if you want to install any themes at this point.
The sole custom kernel presently is the Pershoot one: allows you to OC to 1400 and does play nice with either the stock or the Overcome rom -- there is a thread and you can see the feedback yourself.

Unlocked GSM devices will work on any carrier that uses a SIM card.. i.e. T-Mobile, AT&T, etc. CDMA are the devices without SIM cards like Verizon and Sprint.
You just have to be aware of which carrier and what they use.
(I think I got that right ) maybe someone else can chime in..

Funny, you should ask; I was wondering about the same thing just yesterday:
What I learned, as far as T-Mobile (US) is concerned: it will work - if using a Tmo or AT&T SIM card - but only at 2G speeds, for now (probably until 2013).
That's my finding, and also the opinion of some other fine forum folks here.
Just wish it was wrong...
Well, according to the specs compared between my current I9000 and the SGS3, they have the same bands across the board. So I SHOULD be okay.

What are your download speeds, and where do you live, bro?
4.5-5mbps down. 3mbps up.
I'm in Saskatchewan on Sasktel. It's a 3G/4G network that most devices on it are 850 and 1900 compatible.
Sasktel has boasted LTE in the fall, but only in the main cities, Regina and Saskatoon. Doesn't really affect me because in the city, at work or at home or friends/family, I'm on wifi.

Thanks, man!
So there is hope that it actually may work OK... hmm.
Guess I'll wait some more, and until more folks chime in, as I would not want to gamble $800 (US ) on it... not yet.
Would sure love to buy an International/Unlocked S3 and run it on a prepaid T-Mobile SIM, but that may just not work the same way here in the US of A...
Well, expansys offers up to 15 days to return the device. So I'll know within the first day or so of receiving it if it's going to work or not. I'll have to go buy a MICRO SIM for it or not.

International version for AT&T
I have a question, I am new to GSM as I have been with Sprint for the past 13 years but just switched to AT&T for the purpose of being able to easily swap phones and use international versions. I got the HTC One X but I have to say that it is not "doing it" for me. I am used to the GS1 and then the GS2 and my plan WAS to get the GS3. I don't want to wait until AT&T gets the phone, plus its my understanding that the US versions are dual-core vs the quad.
With that in mind, I was thinking I could easily take my HTC which is only a day old and sell it on Ebay for 2-3 times what I paid for it, and use that money to get an international GS3. Before I do that though I have a few questions about using international versions.
1) With international phones (GS3 or any other model), would I still be able to use my AT&T apps such as Uverse Live TV, myAT&T, FamilyMap?
2) I realize that as long as the version of phone I get has the 850 and 1900Mhz bands, it will be compatible with AT&T for voice and 2G. What I want to know is would I be able to use AT&T's LTE or at the minimum the fake 4G (HSPA+). I don't want to spend $800 on a phone that is stuck on 3G.
3) Obviously I would not get OTA updates from AT&T but I assume that even without rooting I could go somewhere else (perhaps XDA) to get regular firmware updates?
4) Last, for those of you that have alot of exp buying swapping international phones, would you say that if for instance, I would not be able to use the phones LTE on AT&T, and that I was stuck on 3G, if I went ahead and purchased the phone anyway with the intent of using it until the AT&T version comes out, do you think at that time I would still get most of my purchase price back from the re-sale of the international version to use that to buy the AT&T one?
Thank You very much for your help.
I may not be "The Capacity" on the subject, but I have been tinkering with my phones over the last years, I do have some "smartphone cred" and also learned a lot myself on XDA (on the same subject) this weekend...
Let's see if other folks can confirm my answers:
1. According to my information, the US version of the S3 will indeed come with a dual S4 (Krait), compared to the International Exynos quad core CPU. Reason: the S4 can handle LTE, the quad core Exynos not yet;
2. If you buy a (prepaid) SIM card/plan from a 3rd party provider, or from AT&T or T-mo directly, you will be able to use the network you decide to go with. Since only Tmo and ATT have GSM networks, you can only use these with the International S3 and SIM card (Micro-SIM, that is). However, I am pretty sure you won't have a problem using network-specific apps either... since you are using the network/carrier already;
3. As far as the network speed (LTE <> 2G <> 3G) is concerned, I have heard different opinions. T-mo specifically states that you need the 1700MHz band, which the International S3 does not cover. However, they - and I believe also ATT - offer 3G on the 1900 MHz band, which the Inter S3 does pick up.
I have had a good exchange with a nice guy from Canada earlier today (look for MaesterB, the OP of this thread...), and he confirmed that his I9000 does pick up 3G speeds/5Mbps (in Canada). Since the I9000 covers the same bands as the I9300 (S3), I am convinced that it's gonna work to get 3G speeds.
I doubt that it's going to be HSPA+ anytime soon, but you'll definitely won't get LTE - as that depend on the 1700MHz spectrum, I think.
T-Mobile, however, is upgrading their network, and we are supposed to get HSPA+ on the 1900MHz band by the end of the year/next year here in the US... (??);
4. Don't know about the OTA updates... but who cares? You've gotta root your phone anyway to get the most from it. At least, that's my stance. And if you do root, you might as well get the OTAs from the XDA community. Who cares about 'straight-from-the-carrier' updates anyway..?
5. I'm not so sure if you're right with your resale philosophy, especially on 'getting most of your money back'. I wouldn't bank on it. Usually, and once the phone is on the market for some time, the level of desirability tanks, and so does the resale value...
6. Now that I have wised up some over the weekend myself, I'm going to get an unlocked S3, together with a prepaid SIM (probably from 'Straight Talk', 'Simple Mobile', or even directly from T-mo [the latter only with 2-yr contract... yuck!]). If I find out that I cannot get decent 3G speeds (area of 5 Mbps/down) on the phone already the same day I get it, I will return it - and the SIM card - right away and get my money back
Let's see what others can add to this...

There is no possible way you will be able to "sell your one x for 2 or 3 times what you paid for it". You will NOT get LTE on the international version. HSPA+ is 3G and it will get that on AT&T, so yes you will be stuck on 3G. You will still get OTA updates on the phone regardless of what carrier you use it on. Depending on how long you wait you probably won't get most of your purchase price for the phone. If AT&T waits until August to release it you will probably get $100 less at least. Six months later the Galaxy nexus is $350 cheaper, and the One X already only fetches about $500-550.

Sweet.
I was just doing some snooping on my providers website.
EVERYTHING they're doing is in the 850 and 1900 bands. Even the "4G", which still isn't anything to write home about.
Now, as long as I don't suffer from my modem problems that I had after I flashed my SGS the first time (ie. lose carrier once I'm out of my home zone) I'm REALLY set.
(pre-)Ordered my S3 yesterday...
Yeah! Can't wait for the baby to arrive next week!
Also got me a prepaid SIM (AT&T) with Straight Talk, and - just in case - a SIM cutter. Looks like I'm ready to roll!
Let's see how this all shakes out... but it better be good!
I read in another thread here on XDA ("Samsung Galaxy S III... No LTE for $800?!") that the phone will "perform sexual favors and make a sandwich afterward." -- Awesome!!!
Unbelievable, how Samsung pulls these things off again and again and again... LOL
Well, I had to double-check to make sure I asked for 1-3 day shipping on mine. Still waiting for a reply back!
Even if Expansys gets it next week, I won't be seeing it until the week of June 4th OR later.
And it's being shipped to the office where I work. Double-bonus. So as soon I get it, my lunch break will be go down to the kiosk of my provider, pay $10 for the microsim, get it programmed, and voila...done and done.
Hello,
I have an AT&T i777 rooted running Shostock2 and I am looking to buy the international version for my daughter. Trying to separate from my contract lockup with AT&T.
What exactly is the difference between the different 9100 models (G, T, etc), and is there a better one among them? I want the most reliable one (in case the different processors makes any difference in that regard) and also one that would allow rooting and custom ROMs.
Also, it needs to work with any U.S. carrier at the highest speed that they offer. I saw one on eBay but it says "Will not work with T-Mobile or Simple Mobile 3G/4G speeds" and I am not sure why.
Thanks in advance.
Imo u'd decide to get i9100G as it powered by TI OMAP SoC which mostly being open sourced to support better & early development. But if u want it to come with NFC featured i9100P is.

I wonder how much of a "deal breaker" should NFC capability be. Looks like it is very difficult to find a P model in the US. I could probably go with T-Mobile one but from what I read it is a bit inferior to the AT&T and International models.
Then again - what if I do want the T-Mobile's 4G speeds....tough decision

NFC=android beam, mobile cc payments, transferring files by tapping.
And maybe speed will also sacrifices power (batt), like 2G vs 3G/H+..

Well, first of all, it's for my daughter, not me , she is the one who needs to be patient. But her old phone (Samsung Solstice 2, which is a piece of crap) is dying, it gets stuck all the time, turns off by itself, etc. She needs a new phone.
Second, I am not a big fan of Sony phones and/or LG phones. We had LG before (not a smart phone) and it was too a piece of crap. I am 100% convinced that in recent years, when the Smart Phones started to become so popular and companies started making so much money off of data plans, the manufacturers deliberately made the 'dumb' phones crappy, there is no other explanation for it.
I believe that Samsung and HTC are the best phones in the market these days (Android), not really sure I could like a 'Sony'.

You have a few options, but just keep in mind that the standard i9100 has the largest userbase, the most external support, and the quickest official updates from Samsung. In fact, these "similar yet different" models of the first Galaxy S were the first to lose official support. The i9100p may sound nice with NFC, but one feature isn't worth potentially losing out on updates. The i9100G uses a lesser version of the SOC found in the Galaxy Nexus. Unless the storage is a concern, the Galaxy Nexus would be a better (and cheaper) option in this case.
So, that leaves you with the vanilla GT-I9100, and it's still a kick-ass phone IMO. Comes in several colors but black and white are the easiest to find. Bonus if you get the black one, it will work on AT&T's medianet plan, which is truly unlimited data, no throttling, and no wifi hotspot restrictions, and it's $15/mo (or $10/mo if you have unlimited text). I've been using this for the past year and change. Added myself to my wfie's family plan and it cost us $9.99/mo for the line, $10/mo for the data, and that was it. I'm on pace to use over 30GB this month and I don't care

I am 100% convinced that in recent years, when the Smart Phones started to become so popular and companies started making so much money off of data plans, the manufacturers deliberately made the 'dumb' phones crappy, there is no other explanation for it.
I believe that Samsung and HTC are the best phones in the market these days (Android), not really sure I could like a 'Sony'.

Nexus=Google phone
Whatever the brands that google has choosen to be a nexus device is android best choice... the only deal breaker is lack of external sdcard supported..

You could maybe send a PM to a helpful guy called ctomgee.He knows about US phones and could advise you best variant,providers etc.
Once you get a phone,you can then install custom roms etc,which gives the phone a new lease of life.

Hello,
I have an AT&T i777 rooted running Shostock2 and I am looking to buy the international version for my daughter. Trying to separate from my contract lockup with AT&T.
What exactly is the difference between the different 9100 models (G, T, etc), and is there a better one among them? I want the most reliable one (in case the different processors makes any difference in that regard) and also one that would allow rooting and custom ROMs.
Also, it needs to work with any U.S. carrier at the highest speed that they offer. I saw one on eBay but it says "Will not work with T-Mobile or Simple Mobile 3G/4G speeds" and I am not sure why.
Thanks in advance.

About phones working or not working with T-Mobile in the US, this is why; T-Mobile (at the moment, for their overall network) uses AWS for high-speed mobile data. AWS requires both 1700 mhz and 2100 mhz to get 3g/4g, as it uses one frequency for uplink, and the other for downlink. If one phone is not capable of receiving one of the frequencies, then the best mobile data speed the device will receive is Edge.
Now, they (T-mobile USA) are currently in the process of repurposing the spectrum of the 1900 mhz band they use now for Edge data and voice, to use it for high speed data instead. This will allow some phones that currently only get Edge speeds on T-mobile USA's network to get their "4g" speeds. That includes many of AT&T's phones (if they're unlocked), and the i9100, which receives high speed mobile data on 850 / 900 / 1900 / 2100 mhz. (notice the missing 1700 - which is why it won't necessarily get high speed on T-mobile USA's network... unless the market you're in has already had the repurposing of the 1900 mhz band)
However, this repurposing has already only happened in a handful of markets, though the rollout is currently underway.
Hope this makes sense.
EDIT to add:
Also, about the different I9100 variants - there are minor differences between the I9100, and the variants I9100P/T/M.
The P variant includes NFC, the T variant has a slight variance with the SAR values for the radio (so modems specifically for the T model work best for that model), and the M variant is simply a branded regional variant for the Canadian market (as far as I can tell). The CPU/GPU/SoC are all the same for these 4 variants.
The I9100G has a completely different CPU/GPU/SoC chipset, so firmwares, kernels, and ROMs are NOT compatible between this one variant, and the four listed above. But for most users, the performance between this variant and the others are very similar and comparable.
That said, they all have the same antenna/radio hardware, so what I said above regarding data speeds on T-Mobile USA above applies to all of them. This also means they all work just fine for high speed data on AT&T's network.
Ok tom.
I came in here to add to my previous post about which phones (and why) will/will not work on T-Mobile, but Tom beat me to it, so I'll just simply add this:
If you want 2G/3G/4G now and in the future, get the Galaxy Nexus as it's pentaband.
If you're ok with 2G and don't mind waiting on 3G/4G, get any phone, like the i9100, that supports the 1900mhz band. T-Mobile stated that they anticipate their 1900mhz refarm to conclude in mid-2013 and will cover ALL 229 current AWS HSPA+ markets.

Bonus if you get the black one, it will work on AT&T's medianet plan, which is truly unlimited data, no throttling, and no wifi hotspot restrictions, and it's $15/mo (or $10/mo if you have unlimited text). I've been using this for the past year and change.

Thank you for a broad response. I learned something new!
We don't necessarily want to be on T-Mobile, I mentioned T-Mobile because I want to have options...I don't want to be locked to one carrier and T-Mobile offers a great deal with "bring your own unlocked phone, get a sim card with unlimited text/data". So it was just brought as an option for us to have.
In any case, I did offer a T-Mobile (T989) version to my daughter, she "kindly" refused...she does not want to see any logo on her phone . She also doesn't care much about the NFC, even though this can be 'fixed' through an SD card solution if (as she says) "The government will force you to have NFC..." , so I am now just looking for a good deal on a I9100 version.
BTW - what is the Nexus?! I am not familiar with it at all. Does it also come in branded (AT&T, T-Mobile, etc) as well as unlocked?
Thanks again.

Nexus is the 'pure' android phone. Comes with stock android. No OEM bloatware or UI like Samsung's TouchWiz or HTC's SenseUI.
The biggest advantage of nexus phones however, is that they're the first to get any android update.
And yes, you do get it unlocked as well.
Hope it helps.

I don't know why that guy differentiated between the black i9100 and the white i9100. As far as I know, there shouldn't be a difference between them, unless someone can provide us information otherwise.
EDIT: ah. I was curious and did a search on this. Apparently many have reported that their white i9100 gets flagged as a blackberry by AT&T for some reason, causing a bump in their data plan to the 2Gb tiered data plan. I didn't know this. I find that curious.

Interesting. I tried Google for 'difference' between them and didn't see anything. It sounds odd to me, to say the least. Question is - did those who report this issue also had a black one, to compare how AT&T "reads" their phone. Really doesn't make sense, but I am curious too.
Figured I'd come back and answer some questions, but thanks again to Tom for taking care of that To elaborate a bit further:
Whether or not your phone will work on AT&T's medianet plan is determined by whether or not they have loaded the device's IMEI database into their system. If they have, then they can detect your phone and will not allow medianet access. The international SGS3 and the Galaxy Nexus have already been detected. The white i9100 (SGS2) is detected as a Blackberry as it has a different IMEI database than the black or pink models. However, if you do get a device to use with AT&T medianet, understand that they can change this at anytime. Just ask Nexus and SGS3 owners who got caught 2-3 weeks ago
Based on your needs, there are two phones that I would recommend, and here's the links to the recommended purchase places.
Galaxy Nexus ($349)- This is the official Google phone, relatively cheap, always has the latest version of Android. Downside is that is only has 16GB internal storage and no support for MicroSD. 720p screen
Samsung Galaxy SII (black - $470 / white - $530)- The flagship android device from 2011 by most estimates, still a solid phone for today. Comes with 16GB internal, official support for 32GB MicroSD, but will support 64GB MicroSDXC unofficially. , 800x480 screen though. The black one will work on AT&T medianet, white one will not.
If you use on T-Mobile, or a T-Mobile MVNO such as Simple Mobile or Straight Talk w/TMO sim, you will get full 2G/3G/4G access with the Galaxy Nexus (before, during, and after the refarm). As for the SGS2s, you will get full 2G everywhere, but no 3G/4G in areas not yet refarmed. In areas that are refarmed, you will get full 2G/3G/4G. T-Mobile says that the refarming will be complete by mid-2013. You can check the current status of the refarming here:
http://airportal.de/
If you want to get her something top of the line instead of those former-fastest phones, you can look at the SGS3 unlocked, or wait 9 days to see the official unveiling of the new Nexus phone. Who knows, we may even see a $50 price drop on the Galaxy Nexus
That's right.... I want LTE bad. The entire reason I switched to T-Mobile was for LTE. Now the issue is after the sim is activated, LTE disappears.
$50 Amazon gift card if you develop a fix for this. $25 if you give a solution that works!
Let's figure this out! I can't afford an S4 or htc one now....
I don't mean to sound negative or pessimistic but, the LGOG using T-Mobile's HSPA+ service is pretty damned fast as it is... and yes I'd like it to work on my LGOG since it did work not once but twice with two different T-Mobile SIM cards for periods of time but, if you're in an area serviced by T-Mobile's current LTE rollout then you're also getting HSPA+ service too so...
"How fast is fast?" is the question I end up eventually asking people: how fast do you really need the connection to be for a smartphone? What are you folks doing with your smartphones that requires more than ~15-20Mbps?
Also...
Can anyone that is rooted/unlocked (bootloader) and has a recovery installed boot your device into fastboot mode and see if it shows a baseband listed at all? Mine - which is running the stock JB 4.1.2 presently and using the stock JB AT&T radio shows N/A which makes me think there's something going on in there or I busted something during my multiple flashing phase over the past week or so, I don't know. Here's what mine says presently:
FASTBOOT MODE
PRODUCT NAME - mako
VARIANT - mako 16GB
HW VERSION - rev_10 (16)
BOOTLOADER VERSION - MAKOZ10o
BASEBAND VERSION - N/A
CARRIER INFO - None
SERIAL NUMBER - YADDAYADDAYADDA
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - unlocked
Click to expand...
Click to collapse
Now I'm wondering about two aspects there: the MAKOZ10o reference which could be related to the older ICS bootloader since that was a V10o thing, maybe it was updated and now IDs itself as Z10o, I don't know for sure, and of course the fact that it doesn't show a baseband version at all. I don't particularly believe that's what's causing the LTE to crap out and die but, I can't say for certain.
But I'm interested in seeing if anyone else's device running the stock JB 4.1.2 (mine has been flashed with LGNPST directly, not as an OTA - the device could have been 4.0.4 > 4.1.2 by OTA from the previous owner, I have no idea), and of course I can't say for certain when the LTE just stopped working but it was within the first day of me owning the device and before I ever flashed anything or rooted it so I will say that rooting it didn't cause the LTE to stop working and that was the first step in the flashing I've done since I got it.
Still, it's odd that it works then just stops working and never comes back...

For the most part, it's fast.... But it's line having a Porsche with a speed limiter.... Who wants that?
Mine didn't have lte bone stock. I just rooted mine and booted into bootloader and I do have a line of letters and numbers with the baseband.
Bounty is going to be void unless someone has a solution quick! I put it up on craigslist and supposedly someone is going to buy it. Guess I'll have to fork over extra $ for a One or S4
I'm on T-Mobile LTE has never worked for me (been on it about a week). I get week 4g in town and most the time it wont even load ANYTHING! 2G is garbage...... My fastboot shows baseband version as n/a also. Unlocking the bootloader via freegee simply flashes the nexus aboot image which likely hasn't been modified. Does Tmobile LTE work on the nexus/nexus conversion? I know free also flashes a modified boot image but it simply removes the wallpaper.bin file from the phones bin directory to allow removal of any apps (its checks for videos,apk etc etc). I haven't tried flash the T-Mobile modem in the modem thread (.38 or something?) but I am assuming it also wont allow for LTE? Do these phones share modems with nexus or are they just cross compatible? Does the phone run LTE stock? I'm not familiar with at&t and do not know if they have a LTE band. Is it possible the hardware has just been removed on this model for LTE and those that get it do so without the antenna? I know there is another phone where that is the case but I cant remember which one of the top of my head.

As I just noted in another post, the LGOG is fully capable of LTE service on the T-Mobile frequencies - it's a damned Nexus 4 in a different package, with the same hardware radio and I/we can even run the T-Mobile radio firmware as well. That's not the issue.
The issue is that for many of us it DOES work at first but then the LTE stops working and I/we would most certainly like to figure out why it's happening.
Probably tmo trying to force you to buy a phone from them.

Doubtful considering that's one reason they refarmed their network in the first place, so potential customers could bring their unlocked ATT devices to the T-Mobile network and have great service, LTE included. The "uncarrier" has great pride in that fact and have gone through great lengths to advertise it. The issue the OP is having appears to be LGOG specific as I hadn't heard of or seen any other devices with said issue, thus the bounty.

The reason you guys are losing LTE is T-Mobile is slowly switching to a diff band. And it is one this phone doesn't handle. As they convert towers to the new frequency phones that do not handle all the US LTE bands get left behind.

I hadn't seen any information to back this up, feel free to direct me to the info if you'd like. I find it hard to believe as T-Mobile just refarmed the network to support the same LTE bands as att and are still actively advertising the fact you can bring your unlocked device to their network without issue and with full support. In addition individuals are reporting LTE service that works fine initially then ceases generally after reboot or within a few days. The odds of these bands being changed just as users switch in multiple locations to multiple users are slim to none.

I was told this by technical support when helping a friend that has an e970. Whether it is accurate info I guess is now in question. Sorry if it is not.
Sent from my LG Optimus G using XDA Premium 4 mobile app
No worries in the long run, we just like to make sure people do get accurate info. T-Mobile uses band 4 for LTE purposes, and that'll fall within the 850 and 1900 MHz bands they're refarming aka repurposing from primarily 2G/EDGE network usage towards more HSPA+ access which would also get more LTE support there as well.
And yeah, it's irritating as hell knowing it did work and now it doesn't, very frustrating. It's the only thing I haven't been able to get addressed with this LGOG so far and it flat out pisses me off.
Bounty is OFF! I sold the LGOG and picked up an ATT S4 for $185 off CL! Only slight damage to volume button but other than that clean, not stolen and LTE works! Until I bricked it by flashing the wrong rom but it's in the mail shipping back to me repaired !!
I had it running on Simple and I would mainly get terrible edge a I guess HSPA since it would say 4G sometimes. Didn't get LTE until I went over to AT&T.
Can this be done? I ask because I am using the T-Mobile version on AT&T. LTE reception is not bad, it just can be better, especially in low signal areas? Does anyone have any information flashing the G900A modem for T-Mobile? I have searched and can't seem to find anything on this.
Radio and antenna wise, I believe they are the same device specs, so not like a number of years ago where there were antenna differences between them. T-Mobile radio supports all of T-Mobile and AT&T, AT&T radio however only partially supports T-Mobile (NO 4G AWS band, more limited LTE)
There are a number of people that have compared the two variants and no significant reception differences have been found

Right. I understand that. But what I was asking if we could extract the AT&T modem from the G900A (AT&T Branded S5) and flash it on the T-Mobile S5 (G900T). That way the frequencies would be better optimized.
Now my T-Mobile S5 did pick up Band 4 LTE on AT&T and reception was excellent. This is mostly due to the fact that T-Mobile natively uses band 4 for LTE.

I doubt that has any effect at all. Frequencies don't get optimized at least not on your end. I think the phone does have a priority list for which bands to use but it automatically switches when one is better than the other.

I don't know about that. Perhaps it is not "optimizing" but carriers definitely do something to their modems on smartphones to make them work best with their networks. While the T-Mobile S5 works almost flawlessly on AT&T, the AT&T S5 still gets better reception. Perhaps the difference is negligible, but its there.

I am comparing my signal with the T-Mobile S5 from what I experienced on the AT&T S5. While signal difference in good reception areas is not noticeable, signal in lower reception areas is much weaker. The AT&T S5 would send texts messages almost 95% of the time at my work. With the T-Mobile S5, I am getting about a 10% success rate on text messages being sent.

Having an AT&T modem on the Tmobile variant will make the device better handle connecting to LTE/HSPA networks and the phone will switch between frequencies them more efficiently. Now, I don't know if that's possible without bricking the phone.

How so? Would it be the same as flashing a T-Mobile modem?

I am comparing my signal with the T-Mobile S5 from what I experienced on the AT&T S5. While signal difference in good reception areas is not noticeable, signal in lower reception areas is much weaker. The AT&T S5 would send texts messages almost 95% of the time at my work. With the T-Mobile S5, I am getting about a 10% success rate on text messages being sent.

There's your answer right there. T-Mobile released a patch today to deal with poor SMS/MMS or texting issues. Doubt it has anything to do with signal.
Flash the latest T-Mobile update and then see it perform as you'd expect.

Well i was looking to this this with my t mobile s5 with no luck. like another guy said, in good signal areas signal doesnt change but i am in a bad signal area a lot and my phone jst doesnt switch frequecies like it should. I been using att on t mobile phones for a while and installing the att modem but with this one im having some trouble. i have the att modem.bin but when flashing it i get a bootloader response error
You're lucky to get an error and the bin file didn't flash! Please read and search more. There are many threads on xda about similar attempt types. Device-specific modem files cannot and should not be flashed on other devices. They are hardware specific and will cause your phone to stop working if you manage to get it to flash.
Setting up ATT APN settings will suffice for those using att Sim in a sm-g900t.

Yes i realize the risk, and I'm actually not too worried about them. I don't at all think the phone will stop working, however I still can't get the modem on here anyway. I have tried the tar, and bin with no luck. If anybody is willing to put something together I'm willing to test it out. Fortunately in my line of work, it wouldn't be a big deal to get another S5.

I have made all the proper backups. Not to mention I'm not a noob to this, having built a few Roms myself.

If it's not taking in Odin, then I really don't think its going to work. Odin is like the master of all things Samsung for end users. The S5 has a lot of tampering prevention measurements made by Samsung. It wouldn't surprise me if the bootloader is doing a reference check with the modem to see if the modem matches the bootloader.
Also, I wouldn't go about flashing full ATT tar files to the T-Mobile S5. The partition tables are now different in the Galaxy S5 variants when in previous models they were the same. So flashing the ATT full tar could lead to your download mode being wiped.
What exactly is your problem? When you say "not switching frequencies" what exactly do you mean? Like going from LTE to HSPA+ or HSPA+ to LTE etc.
I have created an xposed module for myself that allows me to quickly switch my network preference at ease using a widget. I may share that once I tidy it up a bit. If your issue is being able to switch between HSPA+ LTE 2G etc then the widget should help you. I only use it to force 4G when in a low 4G environment or to force LTE when in low LTE environment.
BTW: What line of work do you do that you can simply get another S5? I'm jealous

Yes I definitely wouldn't go as far as flashing att tar.... And sometimes when I lose signal it takes a heck of a lot longer to gain it back ad t mobile basebands as opposed to art ones. I get another phone about every month and a half to two months so I've definitely tested around on and and also yes when it switches from lte to hspa+ etc it doesn't switch it like any att phone I've had. Takes longer.
And as far as my line of work goes I just mean that I would be able to afford another one if this one broke.

Might be taking longer due to the different radios. Weird though cause if it has an ATT sim and ATT APN configuration, it shouldn't have any delay and function like an ATT phone.
And yeah I'm jealous you can afford a new one if you broke this one takes me a year to save up in order to buy my next upgrade.
