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.
Recently ended up with this phone, wanted to use it on straight talk with a AT&T sim since it is unlocked.
It works, kind of.
I get one bar or no signal in places I have 2 or 3 bars on my old HTC one M8.
I thought about trying a different rom or a different radio if you can flash those on this phone. I am used to the unlocked bootloader on M8.
I even tried the aluminum foil mod around the battery I found on these fourms. Currently I am back on the HTC because this thing gets no service. Any advice would be appreciated.
Thanks,

Search the General and Q&A sections for unlocking radio bands, although I don't personally have experience with this - have just seen the multiple threads.
I finally managed to get into the Verizon hidden menu and enable all supported bands, 2 and 5 were unselectable but I think AT&T uses 4. Still getting spotty service, anyone know if any modems are better for gsm than whatever version is with the stock 6.0.1 rom? I've seen a few post mentioning 12b, is that the most stable or something?
How did you did that? Interested in getting 2600Mhz (if possible)
Hi all, sim unlocked s-off sprint m9 used to work well on android 6 with official rom. But until the phone was upgraded to Android 7. Data connection stopped working for one operator (NOS in Portugal). However Vodafone works well.
Tried different roms and apn settings, same at all. Data connection does not work on NOS operator.
Does anyone have similar issue and of course any advices?
Thank you all.

Why sim unlock a Sprint variant and not an AT&T or T-Mobile which already support GSM?
did you find a solution?
i have exact same issue.
bought one m9 from ebay with sprint (651) firmware on.
lte was working fine in israel (1800 2100).
after nougat im only getting 3g.
it makes sense that i cant use those bands (1 and 3 i think) on a sprint device.. but it did work with marshmallow
Same problem in the USA
I have (nearly) the same problem in the United States with a Sprint CDMA version of the One M9. The main difference is that my data speed is even worse than 3G, around 10-20 Kbps. Occasionally, I get faster speeds, but I haven't been able to figure out if it is location-specific (but always away from home and work) or due to some other characteristic.
The phone came brand new in a retail box from an eBay seller. It worked as expected for 1.7 years. The OTA update which installed Android 7 (aka Nougat) in early 2017 resulted in the very slow data speeds. WiFi is unaffected, but data is so slow that I cannot reliably send or receive MMS; Google Maps says that I do not even have a data connection for traffic info.
EcoMobile (my MVNO provider; I still have a sprint email address, so I know who is actually providing service) could only suggest resetting my phone; did this twice with no change in operation (but several of the programs which automatically re-installed themselves operated differently, including GMail no longer providing auto-complete for addresses).
After literally 2 hours in chat with htc, they told me that my MEID indicates my phone was "made in Taiwan". I took this to mean that: 1) the person I was chatting with had poor English skills (because aren't they all made in Taiwan?), and 2) my phone is gray market (meaning it was not imported into the country via official channels, even though the manual was in the American version of English).
I came to XDA looking for an answer, too. I was mildly surprised to see that this topic was at the top of the list for the One M9.
The best solution for my situation would be the proper ROM for my phone, but I don't know how to figure that out from the MEID. htc USA says they cannot help me with this.
I could even go back to Android 6, but I do rather like the new features in Nougat.
Alternatively, I could root the phone and install a 3rd party ROM, but I still need to know how to choose the proper one for my phone.
I hope this info finds its way to a helpful expert.

Jeff
So the phone itself, as stated is a MetroPCS branded Alcatel One Touch Fierce XL, and according to metro it is in fact UNLOCKED. It is on the latest update of the stock rom from metro I believe (Android Lollipop 5.1.1 ). so that, as far as i can tell is not the complete issue however I'm wondering if it being from metro is contributing to the issue at hand. I am using Mint Sim/Mint Mobile, they have amazing coverage in my area that I myself experienced for a week, so I'm almost positive it is not a coverage issue. Now down to the bare bones of the problem:
I got this phone about two weeks ago now, bought it in "unlocked" "New, Other" Condition on eBay from the seller Cellfeee. Had to use the unlock app when I got it but it went through fine, with no issues. Fast forward I activate my new sim, put it in the phone and experience great coverage for about a week and a half. Phone was lovely. Fast forward more, around 8:30 pm on August 29 2018 I lost service completely. Start journey into google. I have done the following:
Taken out the sim
restarted the phone
tried the sim in other devices
factory reset the phone
rooted the phone, removed metro apps and apn
done *#4636# I don't know how many times
messed with every mobile and wifi setting possible
the only time I have gotten service back was last night around 10, the phone had no wifi connection and it seemed to pick up a very strong signal that faded while i watched.
I have determined that It is NOT the sim card, I have determined it is most likely not the hardware, the only thing left that I can think of is either the ROM or the modem firmware itself. My question is, do any of you think that flashing a custom rom onto the phone could cure this? is there a way to find the most recent stable firmware for the modem and update/downgrade it to that? I've already cut my losses and bought a new phone through alcatel on their amazon link so it's not like i'm completely screwed but honestly I'm so irritated with this phone and I just want concrete answers/results at this point. any suggestions welcome. thank you for your time.
Edit: The service provider in the top corner was mint while the phone was working. after it began to fail it switched to either no service OR metropcs, now it often says metropcs even when no service don't know if this makes a difference

uuuhh ... this is just a shot in the dark here but have you tried the apn settings ??
OK, so I was with T-Mobile forever, and I bought this phone from them at launch. I decided to switch over to MetroPCS by T-Mobile because it's cheaper, so I paid off my phone then unlocked it (Even though I didn't need too, the Metro SIM worked in it before I unlocked it).
It worked fine for two weeks, and I had WiFi calling and everything, and then the RJ5 (I believe?) update came out, and when my phone booted up it said new sim detected, and WiFi calling was gone. My APN settings were set to MetroPCS', so I set it back to the T-Mobile one since it's essentially the same network, but the WiFi calling option is *completely* gone; it's not there, trust me. I call MetroPCS support and they said they can't enable it for devices that weren't bought from them, and I tried to argue like sure you can, send it up to a higher level support team, but I could hardly understand her and gave up.
I went into a MetroPCS store and they had a spare T-Mobile SIM, popped it in, boom WiFi calling was back.
Come OneUI Pie update one, I opt in and update, and voila, WiFi calling is back!
I just downloaded the second update last night, and now it's gone again. This **** is driving me crazy, if anyone can help me figure out a way to fix this I will love you forever.
Wow, that was a gripping good yarn! I think there's a good chance that if you switch to the unlocked G965U1 firmware, it might work. I have an unlocked Verizon S9+ running on TMO, and once I flashed it to U1, wifi calling and volte worked automatically. I'm not positive how it will be with Metro but it is worth looking into. When you flash the collect unlocked firmware, when the phone boots up it will detect your sim and then reboot and configure all the settings for you.
P.S. I don't suppose there's Metro firmware out there?
I don't think there's Metro firmware, because my updates still come from T-Mobile. T-Mobile owns Metro. So what you're saying is flash the firmware via Odin and my phone would be like truly unlocked and I would get updates from Samsung rather than T-Mobile? I don't want to go through all this if it isn't a a certain fix, but sadly there's no way to tell that.

For some carriers, the Wifi calling requires the phone to have carrier firmware. Verizon is one. I bought my 9+ from Samsung unlocked, and it didn't have wifi calling on Verizon until I reflashed the phone (using Patched ODIN) to a Verizon firmware and Wifi calling works... as does the Verizon bloat, but most of that can be disabled with Package Disabler pro or similar app.

I don't think MetroPCS has it's own firmware for the s9+. Plus, they're owned by T-Mobile now. The plan I'm on is called MetroPCS by T-Mobile lol. This is driving me nuts.

Out of curiosity I read around a little bit and it seems to be really hit and miss, which definitely seems to match up with your experience. I did find this post on Reddit from someone saying they got Wi-Fi calling to work with a Metro Sim: https://www.reddit.com/r/tmobile/co...g_volte_not_working_with_metropcs_sim/cymnvhf
Have you come across that, tried any of that?

I have not, thanks for the link, I shall try that. Funnily enough, there was a hotfix pushed out last night and WiFi calling not working was on that list. I now have the WiFi calling icon in the notification bar, and it shows like it's on, but it doesn't actually work, and me pressing it does nothing. The setting itself still isn't in connections or anywhere in the settings. This is so dumb, lol.
