T-Mobile GalaxyS5 m900t LTE issue

Just joined from the iphone world to the android world after about 3 years. Wow. =]
Anyway, just bought the phone yesterday, activated it an within 15 minutes had it rooted phiz recovery and and installed AllianceRom 3.1 on it.
I've had a bit of an issue, It will not go LTE. It only stay on 4g or go to E,, H+, my friend who has an iphone, same provider and same service, his phone shows LTE in our same location at his desk but mine will not go above 4G.
Did I do something wrong with the root process? Anyone ever seen this issue? I'd say its an issue with the service but when you have a friend with the same provider and his phone is showing LTE, it begs to ask questions
Thanks all,
Alan

do a speed test and u will know, i think on yr ROM 4G = LTE, H+ = 4G, also check yr APN too.

Got it Hope this helps new rooters

I checked it out, I found that it was a combination of a couple of things,
When I bought the phone I rooted it immediately, didn't officially update it or anything. I was working on the older radio with the newer Alliance rom which required the latest radio.
The only way I was able to fix it was use Kies, update it, which put it back to stock recovery and stock rom. Reroot using Odin and install Omega's rom. It would of probably worked fine with Alliance rom but I saw a couple things I liked with Omega.
When I updated stock I saw LTE. Which told me that it was a radio issue, I tried updating the radio manually but it failed so I just let Kies do it.
All settled and done, it's purring like a kitten now Thanks Koolboyztn for your suggestion

[Q] No 4G/LTE in my LG G2 D802.

Hey guys,
As you can read in the tittle, my problem is that I don't have 4G/LTE I get 3G+/3G or HSPA+/HSPA.
Right I'm running Lollipop with the custom ROM, BlissPop with B14ckB1rd Kernel. I tried other ROMs (CM, RR, Paranoid) but I don't get 4G in neither of them.
I lost my 4G a quite ago, don't remember exactly how but I can imagine it was when I tried those early Lollipop builds, after that I went back to KitKat and the 4G was gone, even I tried going to full stock but neither that work.
I'm sure is a phone problem because I been with 2 different carriers and couldn't get 4G. The SIM card is brand new and today I spent around 2 hours talking with the Tech Support of my carrier checking everything is all right.
I also tried to change the Baseband/Modem/Radio (Right now I have Cloudyfa KK for the D802).
This might be also helpful for guess what could be the problem, when I dial *#*#4636#*#* go this phone information, down to prefer network type and select LTE only I lose service, by the way, in that configuration I have selected LTE/GSM/CDMA auto (PRL) and USA radio band.
I'm open for all kind of suggestions, If you need more information don't doubt in asking me.: fingers-crossed:

I am having exactly the same issue. I have been going around in circles since days. Recking APN settings constantly etc. Going mad. Would be great to find a solution together!

Well is good to know I'm not the only one.
Could you share more information?, like when and how it happened, so we can figure out what is wrong.
Today I'm going to try to get some logs, and check the system folder.

It happened to me with stock lollipop v30d vodafone ITA with another carrier sim (TIM). Solved after flashing v30a open ITA kdz.

I'm gonna try it, will send feedback as soon as possible.
Sent from my LG-D802 using xda Forum

No luck, I installed the V30a Italian version as you suggested but as you can in the screenshots no 4G at all, when I try to force LTE (This time with the command 3845#*802#) is lose service like in my last ROM, so I'm almost sure is hardware and not software.
Can some confirm me that, cause when you go back to stock by a kdz or how ever their is not residual imformation, every thing is fully clean right? Or some firmware just stay for ever?
If you guys have more suggestions that could try before I send it to somewhere for get it repair.

S7edge SM-G9350-NO 4G DATA**I WILL DONATE $50-$100 TO WHOEVER GIVES ME THE SOLUTION**

The exact model is Samsung Galaxy S7 edge SM-G9350 64 GB GOLD PLATINUM
First I want to get this off my chest. I registered this week (I used XDA before like 7 or 8 years ago in high school when I use to flash custom ROMS on windows mobile phones-good times hehe)because I am frustrated since I bought an unlocked Samsung Galaxy S7 edge from a stranger using craigslist on Sunday night. The ad said it was T-mobile Unlocked and in brand new condition with the box and original accessories and it had some pictures.So why not buy it cheap for since I'm using a T-mobile LG-K7 with a cracked screen,right?WRONG!! The phone is working fine except I am only getting EDGE data!!! I found out that it is a chinese variant and it works fine with my T-mobile sim card here in the U.S.A except it can't connect to 4G and that is probably why the shady guy sold the phone cheap to let it become someone else problem I also saw 1 or 2 of these models in the box as well and he said a friend gave it to him and he is just selling it(B.S.) I forgot craigslist had scammer like 40% of the transactions lol, I use to meet these types of people in middle and high school when I bought and sold my used or old T-mobile phones though I never scammed or conned any one.I remember some people would act shady or too nice for no reason,probably cause they stole the phone and were making 100% profit off me.This same guy is one of them.
ANYWAYS THANK YOU FOR READING MY RANT---- NOW ON TO THE POINT OF FIXING THE DATA ISSUE
I am getting unlimited 4G on my k7 and everyone else on our plan is using unlimited 4g just fine.Samsung rep at best buy said its legit and its an international chinese variant and to look around on here to fix the issue. He told me something about the band and t-mobile towers to pick up the frequency. He said I got a really good deal if I can 4g on there. If not than re-sell it and make it someone elses problem. I looked all around google the past few days an either no one has this problem or if they do than the solution doesn't work on my phone.
Here is what I tried so far:
A) T-mobile reset the network connection via tech support
B) I factory reset the phone numerous times
C)I got the right APN settings set on the phone to be connected to nearest towers, a store rep did it for me to make sure.
D) I replaced and used another activated T-mobile sim card
E) I download some apps I saw on here to check LTE signal etc and its running very slow edge
*********I am on the sim status screen and right now as I'm typing this the signal strength is
-61 dBm 26 asu,cellular network type is EDGE,NETWORK is T-mobile, Service state is In service,Roaming is not roaming,cellular network state is disconnected*******
------I hope someone can pick up information off of that and maybe I could change some settings
E) I dialed *#*#4636#*#* and got to a screen to allow me to check phone information,battery information,usage statistics,wi-fi information-under phone information there are options to set preferred network types to: WCGMA,GSM, GSM auto(PRL), CDMA auto(PRL),CDMA only,EvDo only,GSM/CDMA auto(PRL),LTE/CDMA auto(PRL),LTE/GSM(PRL),CDMA auto(PRL),LTE only,Unknown. It will only stay on up to GSM auto(PRL)
....also when I press menu on this screen there is an option to enable data connection and when I click it,it won't stay,it just keeps saying enable data connection
F)I googled what bands this model and it is able to use and it has the capability to be used on T-mobile bands
What else can I do get the data working to 4G right now? The phone is running Android 6.0.1 and won't update to Nouget over the air. I want to root the phone and see if I can install a custom Nouget rom( since the samsung guy said the phone will brick if I try to install the T-mobile Nouget rom or I can't even do it since its an international variant-by the way I am able to have google services on here like play store,etc. so I don't know if that makes a difference to what variant and rom it is because I heard one or the other of hong kong or open china variants for this phone is better and can't use google play)and maybe I am able to connect to 4G data.
Like the title of this post says, I promise I will back up my donation I really don't want to sell the phone unless I have to because I will not get a better deal anywhere ever again for the latest high end phone from a manufacturer

you have to flash the correct CSC this will fix your 4G if you buy an device from a other country than is it possible that you get this problem but when you flash the correct CSC you will get 4G i helped so much people with this problem with a S7 device, i think this your solution
if this fix works for you just keep your money we are developers not for paying

Maybe you should post this in the T-Mobile section.
In my idea this should have 4G data on T-Mobile US out of the box as the required LTE bands are supported by the G9350. Did you check the APN settings? (VoLTE and WiFi-Calling may or will not work without t-mo-rom but that's another topic)
Also you should be fine to flash a T-Mobile US rom as both have Snapdragon SoC. You don't need root to flash an official rom.
Out of curiosity: what about 3G?

Thank you so much!!! People have actually asked through pm to donate to bitcoin first before helping me and here you are helping me first by the way.
I am going to find the correct CSC, what does that stand for? Can I flash a T-mobile 7.0 Nougat rom on my Galaxy SM-9350 first that the person before you replied about(its the link)?? I want to do both to have T-mobile settings and to use the 4G although the 4G is a thousand times more important. If I can do this than I am a happy man!
Why is there a boot loader and modem link attached to every post containing a ROM download? Does that need to be downloaded first,and what are the next steps,if so? I know these are questions I need to search about they are all confusing and mumbled and jumbled up. Even though I registered this week for help I was a member here like 8-9 years ago in high school when I was flashing custom ROMS on Windows mobile phones(good times hehe) but it got addictive,took a lot of my time from studying, and I totally forgot how do things.

Hey I made a new thread today in Q&A for GS7. The APN settings were put in by a T-mobile store associate and it still didn't work. I don't care about VoLTE/Wifi-Calling although I noticed some people on here are worred about that-its just something I never use.
Are you sure I don't need root to flash an official ROM?The Samsung Galaxy guy at Best Buy said it would brick if I used an official ROM because the phone is an international variant. If I can use an official ROM,I can't get Nougut OTA via T-mobile anyway as my phone keeps saying it is updated even though it is 6.0.1. How do I get the offical ROM manually on the computer? Samsung Smart Switch isn't even recognizing my device when it is connected and Smart Switch on my phone looks like it is only suppose to be used to receive files from another phone? I have the link for a T-mobile 7.0 ROM from a post on here that he used on the same exact model I don't know if I am suppose to root the device first or not yet since it looks custom made.
Thank You for helping me out it means a lot you guys are the best! I can already see myself on here a lot in the future doing stuff different android phones like I 8 or 9 years ago in high school on windows mobile phones.

The only data I am getting is EDGE

So, I guess something is wrong.
You can try flashing the designated firmware for this device first and see if this helps. To get the right one (who knows what all was tampered with) use best the Phone Info tool.

I've had this exact issue before, with a Nexus 5 that I bought from Telus, I am with Telus, it ended up being I had to go buy and register a new SIM card, then it was fine, might not be a solution for you but Worth a try,
Actually get a SIM card from your provider, have them register it in the store

Thanks I did that yesterday already and it still didn't work

What would be the correct CSC file for this device? I tried to flash CSC from a SM-G935t firmware and it didn't work even though she said it didn't matter lol(senior member too)
I am a member because the owner hates the Iphone and I respect that

I'm going to try to find an official U.S. T-mobile ROM and flash with odin...but does it have to be specifically for SM-G9350? I don't think I can find one for that......

1) Download this https://dl.twrp.me/hero2lte/twrp-3.1.0-0-hero2lte.img.tar.html and WAIT.
2) Download superman ROM: https://www.androidfilehost.com/?fid=817550096634750162
I choosed this rom cause it got nougat bootloader and kernel. Also download CSC chooser zip: https://www.androidfilehost.com/?fid=745425885120710484
3) Install twrp via ODIN and uncheck auto reset in odin. Then press power + home + volup to go to recovery. Put the superman rom and CSC chooser zip files on Sd card and put back in phone.
4) Install Superman rom,in aroma pick superstock kernel 'samsung pay and knox work' and install/update everything especially the bootloader. In mods stick to stock as possible.
5) Install the CSC zip file and choose t-mobile USA.
6) reboot and pray everything works LOL
I'm not responsible for any damage that might occur but if ir worked donations are welcome to help a medical student here

Nice, I like what you have! My model is different so I don't know if the ROM will work though I'm almost finished downloading it at the moment. Instructions 3 and 4 is confusing. Don't I need to put superman ROM and CSC file on sd card while the phone is ON?And am I suppose to transfer it on there via usb cable or can I also do it via google drive than open in up phone gmail and put it on sd card? Also do I need to extract the CSC file first to my computer desktop? That file takes forever to extract! Is instruction 4 suppose to be while in recovery mode? Also is it normal for my phone to show "no command" while in recovery mode?

Thank you ?
The rom will work because your phone is exynos based. It got a different model number because it's for Chinese markets. Put the rom on the SD card using whatever method, just do it before flashing the recovery, because your phone may not boot after the recovery to the stock firmware because Samsung has put some crap to prevent using custom firmware. I forgot to say that also before doing anything go to device info - > software - > and press build number several times to enable developer options then back to settings and go to developer options and enable OEM unlocking.
Yes, commands 4 are made in recovery. Install - > pick the zip file and install.
All zip files aren't extracted! The recovery uses the zip file as it is.
Good luck

Were you able to flash the U.S. T-mobile ROM onto SM-9350?
The official firmware can be found on https://www.sammobile.com/firmwares/database/SM-G935T/

I found it yesterday but their free server is under maintenance so he will have to pay to just download a firmware file.
I don't know why don't samsung provide them for free on their site!

Moto g5 plus, single SIM, no LTE on custom ROM?!

Moto g5 plus 64g (single SIM),unlocked bootloader, root...4g works fine on stock ROM rooted w/Xposed
. ..and that's great but Ive flashed custom ROMs
Resurrection
...and Halogen
... and Desolation
... and they are very nice ROM s but I only get 3g (no LTE) and the only info I find on this is a quick-fix w/jio SIM using a DUAL SIM. .... Am I the only unlucky human w/a single SIM 3g problem?
I was so excited about this phone, thought I did all of my research , bought TWO 64g g5 plus phones(not 32g no way because I wanted to BEST lol but its single sim, stupid me).
...should I just give up on custom ROMs ? ...or is there something can be done?
Ive being at this for 2 weeks now...Any/all info very appreciated.

I would've posted in other forum but wouldn't let me due to lack of status....or rep...or bling..or something.

Do you have correct APN set? On some custom ROMs I have installed I had to change APN, because it was set to first in the list by default.

I dont know much about APN ...not durecwhst it's suppose to be set at..im boost mobile.. I'll start researching that next ..thanks brother

No luck.
I found the APN settings on Boost mobile site, I set/saved that to no avail.
I went back to stock/rooted and 4g works fine. But no matter which custom ROM I use I still only have 3g.
Surely someone somewhere knows how to set/fix this.
Can a Mod move this to where someone may have hands-on with this 3g vs 4g issue? Dev or someone?

Month later...5 custom roms later...still either no 4g on custom rom or no camera on simple root w magisk. I still can't post in Dev forum.

No LTE

Have the same problem, how did u go back to stock? TWRP restore? or did you fastboot flash stock fireware? I'm not sure if it makes a difference but after reading a few of these it looks like stock firmware may need to be reflashed with fastboot then start flashing custom ROMs with twrp. If you get the answer let me know if i find out I'll let you know?
Thanks
Update: yes there are ROMs that will fix the LTE problem, I was reading someone with a connection problem someone suggested downloading stock debloated , another suggested AOKP, downloaded both , first I tried debloated got LTE , then flashed the other, for VoLTE. Also I'm not sure if this is correct or not but fastboot flashing modems may work I'm not exactly sure and would need to look it up further is something else I read but didn't try as its 2:00am and I'm being yelled at by a hidden speaker in my kitchen which is why it took so long for me to even try to look for a reason because I've been getting yelled at so long I think I got cancer, I hope Santa brings them a tall glass of shut the f up so I get one day without being yelled at , also Lineage 15 says LTE working. I haven't used it since I don't want to mess with 8.0 right now. MeryXMaz

I'm havin the same issue. Also with Boost Mobile. Most other devices I've rooted have had some sort of boost/sprint/virgin APN fix .zip. But I donno....

Thanks for responding. I still haven't found a fix for the LTE. I will try to aokp again maybe something has been fixed or added. I did fix my camera problem by flashing elementalX so that's good. But not having LTE is not cool. And I also did not want to message w 8.0 yet.

So I tried AOKP to no avail. Still no 4g/LTE. That's time I'll never get back lol.

had the same problem XenonHD seems to work well...

I'll try it thanks

Hoping it'll get better with the official 8.0 release.

Only EDGE available since a couple of weeks

Hey, guys.
I'm currently working on a friend's Nexus 6P and trying to gather some information I may have missed.
Troubleshooting:
Since a few weeks it's not possible to connect to UMTS, HSDPA or LTE (T-mobile). In addition the connection to GSM is pretty unstable.
What I've done so far:
- Factory Reset (problem persisted)
- Unlocked bootloader and flashed custom ROM (Firehound) (problem persisted)
-flashed various vendors and radios (at this point I was able to get a stable GSM connection without "only emergency calls" but still nothing but EDGE is available)
- changed frequencies, preferred network and so on
- placed the SIM in my OnePlus 5 - works flawlessly
- deleted APNs and set it up manually
- changed settings in security to none and rebooted - nothing happened (I read this was a bug in Oreo, so I gave it a try)
I'm pretty frustrated right now. This phone is really annoying. It had a hardware defect just before the warranty was gone (eMMC chip) and please... It can't be another hardware defect right now...
I'm looking forward to any kind of (software) help and hints, I would really appreciate that!
Thanks in advance.

Try using old marshmallow stock rom. It works fine with that version. I also had the same problem with latter versions

Thanks a lot for your suggestion!
Can you recommend any ROM to me?
Never mind... I didn't read "stock" I'll try, thank you!

Okay, so I flashed a factory image (the earliest one from Google, 6.0) and still there's only EDGE available.
Guess it's a hardware defect again.
Shame on such an expensive device. Congrats to you, Google and Huawei
