so i have a Verizon one max running on T-Mobile but i cannot get an LTE lock at all , my girlfriend's international GS6 has 4 out of 5 bars on LTE but this phone for some reason will not grab LTE signal. Edge works perfect HSPA/HSDPA works perfect but when i go to the *#*#4636#*#* menu and select LTE ONLY it still won't get any signal at all. I've tried this on stock while still S-ON , i tried it on the updated 5.0.2 Sense 6 rom , and i've tried on CM 12.1 none of these roms will get LTE, what gives ?
also today i tried changing the NV values for the LTE Bands to support T-Mobile bands 2 , 4 and 12 but still no signal.
From what I have heard LTE is only possible on tmobile and you need to be on CM not senSe

4g wont work on l9, on this phone you can use 3g(internet) segnal or 2g(sms and calls)
to use 4g you must have a phone that support this tecnology(HARDWARE)

Please make sure that after unlock boot loader you flash your original kdz back by offline method. I think it a incorrect baseband problem.

Yea my t-mobile L9 (P769) uses 4g as well, however I do not believe they are LTE capable (correct me if im wrong). Many people think 4g and lte are the same.However they are not.
my phone is lte capable. 4g LTE

That is not true. Not a single LG optimus L9 variant regardless of model or network supports LTE. However they are capable of running 4g just not 4g LTE. The 4g runs off HSPA+ not LTE. Even the LG optimus L9 II uses HSPA+ for the 4g network.
T-Mobile USA seems to define 4g their way. Something like gsm, umts, hspa & cdma, that makes four.

Thats all the radio bands the device can pick up. 4g acctually runs off the hspa. If you change your prefered network to gsm/cdma or umts only or auto it will not connect to 4 g. In order to connect to 4 g you must select hspa+ auto or wcdma+ auto. I couldnt connect to 4g when i first got my phone and its because the prefered network was set to gsm/cdma (auto). I get the best speed on wcdma+(auto). That will make it connect to the fastest radio band available. My phones a t-mobile but I unlocked it and switched to at&t because tmobiles data speed was horrible. I would average .20 mbps - 2.25 mbps (bits not bytes) with tmobiles 4g. On at&t I get 12mbps to 25 mbps and have even got as high as 40mbps right in town. Thats just in my area however, im sure tmobile has good speed in certain areas. After switching to at&t it made me miss my lg p870 I gave my girl because its LTE and she gets anywhere from 20-50mbps!?
I have two Samsung S5's on T-Mobile. One is stock but rooted (only shows 4G) & the other is pure stock and works as expected. Any thoughts? Considering flashing it back to stock and see what happens
Settings -> About -> Status
Mobile Network Type.
Does it say LTE on both?
check service menu
*#2263#
Mobile Network Type =UMTS for the rooted phone, LTE for the stock. Ok I got in to service mode, what should I do from there?
On our galaxy S5 the 4G alone is really 3G, the LTE is really 4G speeds. T-mobile had the speed reporting configured this way on our devices. I did a comparison over the weekend, my phone was running CM11 and my wife was running stock. Mine would show either H+ or H (3G GSM) while hers showed 4G.

I have noticed that while in 4G the speeds were remarkably similar to 3G, I thought it was just My phone acting like that....
I've had this issues since I got my S5. TMO only gives me 4Glte and 4G, 2G. No 3G.. I only get 3G on custom ROMS like BlissPop 5.0. Any resolutions?

Why would you want 3G?
Having 4GLTE or 4G is a good thing..

Not when I only get 1 bar of it and full 3G bars from what i've experience on custom ROMS.
I dont think there is even icon for 3G in factory tmobile room. 3G and 4G pretty much fell under 4G. If you want to limit yourself to 3G only you may have to research some other forums with 3G tmobile phones and find older apn setting. They should work with S5 just with limited bands. I remember from my Note 2 days that for a while older apn (4G) worked much faster than newer fast.tmobile lte apn.

Tmobile does have 3g. What happens is during inactivity the connection falls back to 3g to save battery, and transfer very small amounts of data. When demand calls the connection than hops over to Hspa. Tmobile does this transparently to the end user on most devices. This is what they call there 4g network.
If you use international roms, you'll see the indicator change between 3g and H all the time. Same with the nexus line of phones.
. Could someone please help me find the correct settings to make A Verizon LG g3 work on AT&T 4G LTE in Birmingham Alabama. I have already gotten a SIM card that is supposed to work on unlocked phone from AT&T however for some reason I cannot get 4G LTE only H and when I use speed test it only runs a maximum download of about 6.5 mb/s where is the same sim card in my htc m8 will run an average of about 25 mb/s I have tried various APN settings obviously I'm doing something wrong any suggestions will be greatly appreciated thank you in advance
You Must be on 10b or 11b radio with a non stock (Cyanogenmod or AOSP ROMS) to get LTE working on AT&T. That's the only way I've ever been able to get LTE working on my VS985 on Cricket Wireless (which is owned and operated by AT&T). If I use a Stock 5.0 or the recent stock 5.1 ROM with the newer radios (12b and up) I will only get H+.
There is no fix for this that i'm aware of other then running Cyanogenmod and 10b modem.
The Verizon LG G3 (VS985) only contains LTE Bands 4 and 13 (plus the unlockable Bands 3 and 7). Band 13 is only used by Verizon, while Band 4 is used by T-Mobile and somewhat by AT&T in major cities. Outside of those major cities, you'll be on 3G (H+).
If you plan on sticking with AT&T or an MVNO of them, you should pick up the AT&T model G3, as it has AT&T's primary LTE Band 17, and Bands 2 and 5 that they use in some markets.
Hello,
I am using Redmi Note 3 SD version. I have used it since December 2016 with Jio(India)
It worked perfectly. Now after using it with Vodafone 4G , i faced issue with 4G and most of the time got 3G network which i thought was restricted to that carrier.
Now i switched back to Jio and 4G drops constantly in some areas where other phones work perfectly with same SIM
I unlocked Bootloader flashed old MIUI version and rooted my phone
I installed Network Guru in that
for Band 40(2300) it drops constantly with LTE RACH being Radio Link Failure and Failure at MSG2
When i lock it to BAND 5(850) it works perfectly. Can someone help me find out whats the issue? I would love to get back to using all the bands as this may prevent me from using network in some areas

My kenzo has the same issue with China Mobile(China).
Failure at msg2 for band 38, band 40 and band 41.
Currently, I lock it down to band 39 to get it work.
I tried another SIM card by China Unicom doesn't have this problem, it uses band 3 and works fine.
Tried to flash the original ROM and modify the NV with QTSP but didn't work.

I think its an hardware issue, replacing the motherboard might be the only way
