new baseband on t-mobile US - Optimus One, P500, V General

Would someone point me in the right direction or explain why the new baseband has problems on t-mobiles US network?
I have been searching and cannot find very much.
Thanks in advance.

If I may elaborate on what Jrhodes85 was saying:
With the new baseband, the 1700Mhz band (which accounts for half of T-mobile's HSDPA coverage in the US, among other carriers) is completely unstable, if not non-existent.
Most international carriers' data works great, but O1 users in North America and possibly a couple other regions are slowly getting pushed into obsolescence.

So does this mean that T-Mobiles network is using a frequency hardly anybody uses which also means future ROMs which are build upon the new baseband?
I am not with T-Mobile USA because I am also German but because I feel they are the only company which uses GSM smartphones and has reasonable prices for data and voice.
ATT Sprint and Verizon in my opinion are drastically overpriced for they bad product they deliver and MetroPCS or BoostMobile seem to have questionable reputation when it comes to service quality.
What would this mean for our future with T-Mobile?
What do they do with new smartphones? They also use the old baseband?

The baseband is just the software that controls the phone's radio systems. It so happens that the baseband released in Europe apparently does not support the 1700 mhz part of the spectrum that carriers like T-Mobile broadcasts their signal on. I highly doubt that LG is passing on supporting an entire frequency range, as that would be a terrible business decision considering there are more carriers than just T-Mobile using it.
The spectrum T-mobile broadcasts on has other issues (no clear roadmap to 4G, etc), but you won't need to really worry about that for years.
To the OP: How does this manifest? Well, after flashing the new baseband, my data speeds have slowed down considerably. Google Music is now unusable, yet I am still able to make voice calls and send texts. I am not on T-Mobile, but I am using an Optimus T on WIND here in Canada.

Thanks for the responses.
The other day I briefly switched to the new baseband. One thing I noticed was that I had 3G in my office whereas before I did not, I don't know why, but I didn't notice any really problems. Only after reading a few things that others were saying I decided to go back to the old baseband.
What do the new tmobile phones have for a baseband? If they are on gingerbread are they on the new baseband? How does that work?

well I have a 30 MB dataplan hahah so I can somewhat not care about G3.
I mainly use it for Google Maps sometimes and thats it.
I am to cheap to pay more than 30 Dollars for such services. If they would charge 5 dollars for 500 MB ror so I would do it.
Well I hope that the baseband modem drivers for the LG Optimus at one point can support both frequencies as I just learned that this
is a driver option.
The German iPhone can be made to work in the USA when you just hack into the phone and activate the frequency used in the USA.

Tmobile isn't really anything compared to AT&T or Verizon, they honestly have far superior phones...in the days of the g1 which ran specifically on tmobile usa was easy to switch radio...back than it was Radio SPL and was as simple installing as flashing any rom or kernel...my question was simple....
Can tmobile users in the US have new baseband that provides working mobile data (3g/2g)..because without it working, the phones practically useless without wifi

Unless someone is able to merge that portion of the old baseband with the new baseband, I sincerely doubt we're going to see this resolved.
T-Mobile seems to have no interest in pushing LG to update the Optimus T to Gingerbread. Either that, or they're waiting to improve the adoption rate of Gingerbread on the G2X before they bother with older phones (horrible logic, if you ask me).
I hate to say it, but there may need to be somewhat of a divide among developers if certain roms can't be built for both basebands. Of course, this isn't anything new for the Optimus line. The Optimus V is all on its own, too.

Well i know that on the openoptimus ROM new Baseband 3g works fine but not on the other ROMs thats why i thought it was a apn issue but i never got a chance to check cause i bricked mine going back to the v10 baseband and got a new p509 from warranty, and as far as tmobile update i highly doubt it because i know someone that works for tmobile and he said they are phasing the phone out they are not even on the shelf at most stores i wish some one would just let us know is it just the apn setting cause we can put those in manually here (I have a link if anyone needs how to do that PM me) i just gave my P509 to my girlfriend so i dont want to try and then have her not have data when she gets a new phone i will try but not right now

so based on what you say
the new openoptimus rom once stable and running fine on the Optimus T would allow full access to 3G ???
I bricked my phone wanted to do a replacement and the guy on the phone at T-Mobile told me they dont because they dont support it anymore.
So I guess you are pretty right with your assumption.
Fortunately I was able to recover it on my own.

That is just sad.....about tmobile phasing the OpT out, its one of the best entry level smartphone they provide,even when I walk into to pay my bill I still see people buying the OpT....that's why I enjoy devs like andy and bytecode, they're all developing with old baseband

I agree - if the camera would be better I would more than happy with this phone and not need more.

Yea its a good phone I loved my Optimus and in fact still do I mod it for my girlfriend now for fun but I will tell you going from the Optimus to this phone (HTC Sensation) is amazing I love this phone and if you are going to upgrade it is a great phone, granted the Tmobile gs2 had more storage and a better processor (there is really no difference) the development in the Tmobile version of the galaxy s2 is slow and week as hell almost all themed ROMs while mine has great ROMS full working ICS ROMs both with HTC Sence 3.5 and stock ICS ROMs as well as official support for cyanogen mod and Miui which the Tmobile GS2 doesn't have just a little tip to my fellow Tmobile users .....anyway back on topic I'm pretty sure we can get the new baseband cyanogen mod working on our Optimus t and I will figure out how as soon as I get my girl another phone

I am almost certain that will not be the case. Android developers, while talented, are not electrical engineers and developing firmware to run a 3G radio is far beyond their skill set. The only possibility is for LG to update with a new baseband that doesn't screw over Optimus T users.

all of these new baseband scares me now.
I am using the new baseband on Optimus T on Mobilicity network (1700)
is there a risk that I may bricked this phone?
I am using Adam's N1 CM7 , with V20G baseband
It works well for me and I love CM7

I dont think you can brick the phone just by flashing the baseband.
And the baseband discussion is an issue with the T-Mobile service in the USA as I think in Europe it works fine and I think Asia should be the same.
Does Indonesia use GSM or CDMA?

I don't think you ruined your phone. I had mine on the new baseband for a couple days and didn't have any problems. I reverted back to the old one and it has been just fine.

I have an Optimus One T too, but I bought it unlocked on eBay. My carrier uses 2100MHz for 3G where I live. So far I've had no problems with the old baseband. I'm using CM7.1 (mik_os 6.5.8) but would like to try adfad666's latest versions, which only support the new baseband. Do you guys think it would work?

I've got a lg-p509 optimus-t in the U.S., do I understand correctly that I'm on the old baseband since t-mo never did the official gb update for this phone?
When I check in "about phone" my baseband info is the seemingly meaningless "V07u-000-000-mar-23-2009" not v10 or v20g etc.
P.S. I'm running adfad666's cm-7.2.0-RCO-optimusone-kang with goldenleaf 2.6.32.9 #1 right now with no issues to speak of.
Update: I booted windows and installed the lg mobile support tool which seems to show I'm at v10s, which they want to update to 10L maybe??
"get info" button returns 10s and main lg tool window shows 10L below my phone model.
it says update available, but is kind of short on detail.

[Q] Wind vs. TMobile Amaze plus a couple of other questions....

Hey all!
Sorry if this has been asked before (I've seen posts about it but no straight answers on the issue).
I have a brand new T-Mobile Amaze and a brand new Wind Mobile Amaze. Long story about why!
I can't decide which to keep. I like the fact that Winds is unbranded. I would probably like to use the wifi calling feature on the T-Mobile one when I visit the US (I spend 5 months in the US and the rest of the year in Canada). I don't think I want to root this phone....am undecided right now. The thing that bothers me though, is the camera program on the Wind Mobile version. It's completely different and I like the T-Mobile one better. If I DID decide to root, could I get the T-mobile camera on the Wind one? And then, how would wifi calling work?
Sorry, I'm a newb who is not savvy about any of this stuff....
Any help would be appreciated
Also, I read something a while back, that the bands are different between the two versions. Is this true?
Thanks in advance! CHEERS!
I'm no pro and please correct me anyone if i'm wrong but yes. the bands are different, which is why there are different RUU's for the telus, tmos, wind etc amazes.
I'm pretty sure if you kept your wind mobile one and then followed the procedure to root the device, you'll be able to use the ROM's that we have on XDA and then in my opinion that would give you the camera from the T-mobile one (most likely unless it's been changed) - but yeah don't hold me 100% accountable for this.
You can flash a T-Mobile based ROM onto the WIND's Amaze. With this, you will get the camera interface from the T-Mobile Amaze. I'm not sure about WiFi calling since I never use it - actually I don't even know if WIND has WiFi calling on their network.
Keep the t mobile one, wind one is not yet compatible with the kernels supplied by custom ROMs for now. Means anything with faux kernel
I know it says compatible with all the htc amaze on the kernel page but it is not for the Wind
Thanks for the replies
Hmmmm, I may think about rooting after all....I am looking at both the T-Mobile and the Wind site....
T-Mobile Amaze:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100);UMTS: Band V (850)
Wind Amaze:
3G (UMTS/HSPA) AWS 1700/2100 2G (GSM/GPRS/EDGE) 850/1900/900/1800
They look like the same bands to me. (??) I really like the unbranded Wind one. I'm not sure if I would ever use wifi calling when I had the phone in the US. Could I potentially add the T-Mobile wifi calling to a rooted Wind Amaze do you think?
Thanks so much once again. Sorry for the dummy questions....!
Wind's Amaze bands are (from the box, and I have verified that I could connect to both T-mobile and AT&T bands while in the states):
HSPA 850/1700/1900/2100.
GSM 850/900/1800/1900.
Kernels from Faux do work on the Wind Amaze (at least, they did for me when I was running custom).

I don't know what you're talking about, but Faux kernel works fine with my WIND Amaze.

Your videos work fine after? camera still work???? maybe you have a slightly different variant, but recent batch seems to be incompatible.
Hmmm, now I REALLY don't know what to do! I guess I will keep the T-Mobile one since I have already been tinkering with it...that keeps the Wind Mobile one brand new so I can resell it! I suppose I can be a girly girl and put some swarovski crytals over the darned T-Mobile branding!
Now, next step is to find out how to get the wifi hotspot working. Have been reading up on this. May be easier just to root it.
If I unlock it and use it on Wind, would the wifi hotspot work without rooting it?
Thanks again everyone
if i was you i would keep the wind one ... why? because the tmobile branding is a HUGE turnoff when you are looking at your screen (sorry americans!) They are generally the same device just with no branding, you could push an apk to your system folder or apps cant remember and it should work as long as you have a t-mobile sim card. In canada we do not have wifi calling so it wouldnt working here (duh!) Good luck with your pick! what i would suggest be the breaking point is check if either device has S-OFF if it does you could sell it to a developer (possible a little cheaper so they can start making roms and try to achieve s-off in all other devices.) Good luck with your pick, basically theyre both the same device.

Heya!
Ok, so they are the same device exactly....hmmm. So, wifi calling isn't as a big deal as the camera software. I want to make sure I could for SURE have the T-Mobile Camera on the Wind phone. And if I root the Wind one, I am assuming the start up animation can be changed. The Wind one is lame. T-Mobile one is much better;-)
I am not sure what S-Off is....but can you tell me how to check for that?
Thanks a bunch!

you have to boot into bootloader (by removing battery then - pressing volume down and holding it down and then press power button (you should keep pressing both power + volume until you get into bootloader.) if you install a custom rom like bulletproof or sense 3.5 you will get The new Camera APK and bulletproof has wifi calling included good luck!
I don't know why people keep saying that T-Mobile and Wind are different bands.
You do realize that the reason why Wind doesn't get different phones from T-Mobile is because they use the same bands, right?
If the phone doesn't work on T-Mobile's standard 3g+ network (AWS) it won't work on Wind, and vice-versa.
The only thing you need to worry about it is it being sim-unlocked.
The different RUUs only exist because of carrier customization and locking. Wind's Amaze RUU is pretty much stock without the extra bloat of T-Mobile Apps. But of course, the T-Mobile RUU also has the updated camera function, unlike Wind's.
Also, that's the first I've heard about Wind Amaze's having problems with faux's kernel. FYI my Wind Amaze's camera works fine on faux's latest kernel and NRG's Energy ROM (and xboarder's when I used his). However, mine was manufactured in November, so YMMV.
Actually youre a bit wrong on that, T-Mobile does support 2G network so any phone with 2G bands (such as iphone or galaxy note) will work on T-Mobile Network with 2G Internet Speeds. And the RUUs are made for the carrier specific device so if you want to revert stock always use ur own carriers RUU!
I know, that's why I mentioned the standard 3g+ AWS network. If it doesn't work on the 3g network on T-mobile, it won't work on Wind's Home network which uses the same 1700/2100 band (also why people tend to buy T-mobile phones and use them on Wind's network).
And yes, reverting to stock using the same RUU is a good idea. However, from my experience with Motorola's SBFs, they are interchangable among the same device. Because Wind didn't have a publicly leaked SBF, we've been using other carrier's SBFs without problems when reverting to "near" stock.

i still dont know why tmobile version is the only one that have all those camera features, the wind version of the Amaze have the old camera UI like the sensation does, but im sure there should be a flashable zip for the camera like tmobile amaze version is.
anyone that had the sensation 4g knows what im talking about
i dont know if the same flash zip file from the sensation works or not, im not a pro but i figure it wont cause its made to work with the sensation,
another thing guys, they have a blueray feature for the camera when recording, you guys think it can be port over to the amaze?
If you rooted your phone, I have the tmo camera apk for you.

[Q] LP500 on US T-Mobile

I have T-Mobile service in the US. The phone that I got originally from T-Mobile was an LGP509 with the V10s baseband. I flashed the new baseband (V20g) and it always worked fine for calls, 2g, and 3g. That one died a slow and painful death, so I went to Amazon.com and bought an actual unbranded LGP500. This one came with GB and the P500-M76XX-V20g-SEP-21-2011-XX baseband. The problem is that 3g has never worked on this phone since I got it, even though 2g works fine(but slowly). I noticed that the Baseband was a little different from the the one I installed on the old P509 ( which had a JUN-14-2011 date in the name), so I flashed the V20g JUN-14-2011 basband hoping to restore 3g. Successful flash, but still no 3g. Anyone have any ideas about how to fix this? Is it safe to flash the p509 V10s (old Baseband) to a p500 to see if that works?
I guess my question is this: Is there ANY hardware difference between the p500 and p509 that would prevent the p500 from working on T-Mobile's 3g network? AFAIK, the differences are in the radio firmware (baseband). Am I wrong?
Any help is much appreciated.
Forgive me if this is addressed anywhere else. For the life of me I couldn't find posts about anyone who as a p500 and wants to flash a p509 v10s baseband to it.
I dont think p500 will work on tmobile 3g
because optimus t is p509 with 1700 aws band
Thank you, you are absolutely right. I've been researching this issue today, and I'll share what I've found in case anyone else is interested/cares.
I got my hands on the elusive p509 service manual today. I've been comparing it to the more common p500 service manual. It looks like the two share a common PCB, but there are vacant sections of each phone's PCB which are populated on the other. These sections are essentially filters for the radio signals coming in and going out through the antenna.
The phone's software just selects the WCDMA antenna and whatever filters are in place determine which band is used.
I had originally thought that the capability was available in every p50x phone, but that it was selected based on available networks. I assumed wrong.

Rezound south korea

So I am leaving Montana for south Korea soon and was pretty excited to learn that my Rezound is global capable. The only thing is I am unsure if it will work on a Korean SIM card, or how to do so. I am s-off running the first leaked ics ruu. Do I need to ruu to the global firmware? Or will any gsm capable roms work without a firmware update? Also, if there's any one out there who has been to south Korea and could give me some tips on providers to choose from it would be appreciated.
Sent from my ... Rezound
You need to install the official Global RUU, leaks can be problematic because they prevent you from getting OTAs on stock rom and may not be the latest, most stable software.
I think there have been like 2 official firmware upgrades and several leaks between what you are running and global.
You do need a GSM enabled ROM, and one that is based on the global firmware. Simplicity or Newts One XXX 5.08 may be good options for you if u want to stick with a Sense ROM.
You may still need to call Verizon re: international calling, although I wouldn't mention I was rooted.

Thanks for helping. I was a little unclear in my original post however; I actually am running Newts One XXX 5.1.0 currently (awesome by the way). What I am wondering though is this; will the fact that I am not on the global firmware mean that I will need to RUU update in order to get service with a South Korean provider. I do not plan on trying to remain with Verizon as I will be in South Korea for more than a year.

rezound in rok
I'm also heading to the rok and hoping to use my rezound. I'm on stock ics ota. I'm going to see what I get on a stock rom before I do any unofficial releases, but I expect to drop SMS capabilities or maybe data like you see in the states with a T-Mobile sim in. I arrive in Korea on the 31st so I'll update sometime late next week and let you know. I've been to Korea before and I believe we will have to go with SK Telecom as our carrier because it is the only GSM network. The other networks are cdma to the best of my knowledge. Hopefully my next update will be from my phone on a Korean network!
Rezound in South Korea update
In Korea now. I just flashed my phone from a stock OTA ICS, unrooted, s-on over to the Global RUU found on Androidpolice.
I have tried to buy just a sim card from several stores, SK, KT Olleh etc, and the stores all say that I have to go to the headquarters stores located in Seoul, Yongsan Train Station on the top floor. Apparently this is the ONLY way to get a sim for a global phone, other than having a korean national get one for you and give it to you. This weekend I will be going to the headquarters stores and getting a sim, Other problems you may run into are related to being a foreigner in Korea. They will sometimes not want to sell you a phone on a contract because you as a foreigner could disappear at any time without paying the bill. So, they will try to get you to buy prepaid. I don't want to deal with prepaid anything, but that may be a viable option to get a SIM card easily. Just buy a reallllly cheap prepaid phone that has a sim in it, pull the sim and throw it in your global enabled device. Unless you speak Korean, navigating to the headquarters and getting what you want may prove a bit difficult. Fortunately, I do speak Korean, so I will let you know how it goes.
I will update again once I actually have a Sim in my phone!
Thanks for the valuable information so far. I will be arriving there at the end of November and am looking forward to hearing more about how It's going for you there.

got a sim, no data!
Finally got a sim from KT Olleh today. The girl at the counter didn't believe me that the phone would work, but I got her to do it anyway. By the way, don't try to set up service for a phone anywhere in Korea on a weekend. They cannot activate a new phone unless its a weekday. So anyway, got it all setup and the girl sits there and plays with my phone for a while without saying anything to me. Then she tells me that the calling and texting is fine but the phone won't get a data signal. I asked her to set the APN, and she said she did. I checked it out and she had put in the KT APN as alwayson.ktfwing.com Looks right to me, and she seemed to know what she was doing for the most part. Then she started to go on about how Korea runs on CDMA for the most part and not GSM yadda yadda.
So, I have a Rezound, working for incoming and outgoing calls and text on KT Olleh, but no data signal at all. I might repost a similar message in another forum topic to see if any gurus have any advice on how to get it working. Also going to do some more research. I'm new to this but there is tons of information out there. I will post again once I have resolution or give up and buy a new phone!
PS Phones in korea can be REALLY expensive. Dropped 850 on my wifes LG phablet (optimus VU2)!!! Equivalent to the instinct in the states I think?
didn't flash twice
So, I am a phone noob, and did a lot of reading last night. Saw that most people flash rezounds twice anytime putting on new firmware etc. I think I will try that tonight and see if I pick up the data signal.
The ruu's generally need to be flashed twice. However I did not need to do so going to the global, the ruu automatically took care of everything.

The rezound may not have the radio frequency that network uses. That would be the main problem as to why you aren't picking up data.

Some helpful information that KT Olleh has to say about using a non-korean phone in Korea.
I am currently in Seoul and have rented an Evergreen Mobile Sim Card that works on KT Olleh's network. I am curious as to whether you were ever able to get your Rezound to work with their Data network, and if so, how? Mine works with Olleh Wifi for free but will not even recognize the 3G, despite my having changed the APN settings, and even going to the Evergreen Mobile office in Yeoksa-dong today (they said they couldn't get it to work after an hour of fiddling with it themselves).
Suggestions? Do I have to root?
Oh, and the link in your above post has expired. Could you summarize what KT said?
Thanks!

$50 bounty for LTE solution for TMobile users!

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

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.
Guys really need to quit buying e970s and thinking lte on tmo will work.

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.

SM-G850F and SM-850M what's the deal ?

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.

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.
