[Q] Verizon NC5 rooted to work with T-Mobile SIM - Verizon Samsung Galaxy S 4

hello, I'm hoping someone might be able to help me with my issue. I was given a Verizon Galaxy S4 that had stock NC5 on it. I have T-Mobile as a carrier. I successfully downgraded/upgraded back to NC5 rooted. Everything seems to be working properly on the phone. Now, I'm trying to get my T-Mobile service working and am having issues. My only options are Global, CDMA/LTE, GSM/UMTS. No matter which I pick I get nothing. I can get into service mode, under UMTS, and bunch of menus down, Network selection, and I can choose GSM/LTE, but when I reboot it doesn't stick. If I choose it and don't reboot I get good GSM, but my data is very sketchy. It jumps from H to H+ to 4GLTE. When I do a speedtest I can get up to 1.5mb/s but it gets stuck when doing the upload speed, and it just seems to be not working right. Although speedtest says I'm getting 1.5mb/s when I do any browsing it seems like the internet is dropping in and out. Is there another rom I need to jump to or something I can flash or change in the build.prop to make this work stable on T-Mobile, hopefully sticking through a phone reboot. This phone was going to be my wife's but I can't give it to her not working "normal".
also, I think I have went through every thread concerning this subject and get any of the suggestions to work, I'm thinking maybe it's because this rom is NC5 and maybe those threads were written for previous versions like MK2, etc.
any suggestions would be greatly appreciated.
thanks!

Calling all Canadians! Bell Telus and Rogers users.

Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

Bell note here. Been. The at & t roms with no problem.
The only issue that I have is the Yellow Pages crap that appears in my contact list as well as at& t bloat depending on the rom. Easy enough to deal with though.
Aside from that, it's been perfect.
Currently on Team Perfection 4.0.4.

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Thanks for the tip. But I got everything running again. I did have LTE to start, and have a LTE sim card. The *#2263* certainly helped. And Flapjaxxx's GPS tools in his ROM helped me get the GPS back up to par.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...

SGH-i717D Fido Netowork/Modem issues - How to dump NVRAM/force Qualcomm USB Settings?

Hey guys... I just picked up a
SGH-i717
v 4.0.4
Black Star V LF6
LTE Sim, LTE phone, downtown Toronto
I just picked the phone up on the weekend.... It's my first unlocked phone and my first rooted phone. I can't seem to get a network connection (I'm with Fido).... initially I tried a number of APN settings as I browsed through various threads on APN settings for Fido, Android and Galaxy Notes. Over the weekend I had connection of approx 1 to 2 bars, and was at least pulling light bandwidth off the edge network. I called Fido last night to have my network settings reset, and since them I haven't been able to get on my network. It seems to jog between no connection, 1 bar and 2 bar signal strength. Where before it said it was on the edge network it now does not connect to a network.
Calls to Fido show that everything is set up ok from their end; they can't support a non-Fido phone, and they say that they can't guarantee I'll get more than 2 bars connection on any non-fido phone. I was making calls & texts from the phone on the weekend whereas now, following the network reset from Fido, I have no connection. Yet when I Reset to Default the APN settings it populates the fido LTE apn without issue.
I'm lost... could someone please help me out here? I have no experience with either rooted phones or unlocked ones... and my furious googling and thread browsing just seems to be hitting the same recycled threads.
'
Where I'm left is now it's saying 'Not Registered On Network' regardless of the APN setting I use.
You need to check your baseband, or modem. And verify you have the correct one for the fido network.
I Dont know which radio image is going to work for you, but it sounds like the rest of the device is fine.
Check in the general section, and open the "super everything" thread.. There you will find many solution threads, and possibly the correct radio image to get your device running properly.
Radio images are almost always a .zip file that is flashed in recovery. and they are very easy to use. You simply download the image you want to try, and place it on your SD card. then boot into recovery and flash the file....reboot, and test.
You should read up on the flashing method too, and ensure that you understand exactly what you are doing "before" making internal changes to your device.
Additionally, you should make a nandroid backup of your current rom, just in case something goes wrong. then you have the ability to restore the old build and get the phone running again.
read, read, read....it's the only way to grasp this information...
good luck.....g
Thanks gregsarg, that's a great start for me. I will throw myself into that direction. Thanks again for your help.

Well, a slow evening with little progress. After reading much, I ran a backup and tried installing a radio...no error message, just says installation aborted... not sure what tdsp is but I tried downloading and installing goo manager as I read where CWM (which is what I.assume I have now) doesn't work that might, but the installer which was supposed to have rebooted my phone and installed, it did not. This was a good 3 hrs and I was spent for the night. Guess I'll keep plowing away tomorrow.
I created a TWRP backup and have begun flashing different radios/modems... When I try to access mobile networks with the different radios installed none seem to work... .... so far I've tried:
Blaze_4g_LB7_radio_ATTNOTE
icsblaze
ROGERS_MODEM-CWMXLA2
UVLG3modemfori717
VK1_Test
KID_TEST
I've always wiped the dalvik/cache before flashing a new radio. My baseband was i717UCLF6, but after I restored it's now T879UVLG3, which is wierd because UVLG3 was the last radio I installed before I restored. I assume the radio didn't restore and I'm now using a T879 radio as opposed to an i717 radio, but it does not prompt me for a sim card after the restore. I can select a preferred band using the *#2263# command, but none seem to drive a better signal - I'm still idling somewhere between a no-signal and unknown network (most of the time) and 1 to 2 bars. Some of the above recognized my sim and suggested either HSPA, GSM, etc on the *#2263# command, others showed nothing when I did that.
Am I correct in assuming I just need to keep doing this until I find a compatible radio and upon flashing and rebooting it will simply connect with a solid signal? Is there any more specific versions of radios I should be targeting?
Re: SGH-i717 No network connectivity
The modem isn't changed or restored when you restore a nandroid or flash a rom.
If your goal is t-mobile or wind or simplemobile. You have the correct modem installed.
Just go to settings and input your APN and save it. Not every rom has the apn's , and not every carrier automatically sends the apn settings.
Thanks Ranger... my goal is to get it working with Fido... but I'm not sure if that's synonymous with T-mobile or Wind yet
and ngretud
Anyone else have any input on Fido radios? I can seem to find one that works for Ontario....
consistent tomsisu
I've now tried the following radios:
ICS Kid
ICS Telus
ICS.zip
ICSblaze
Kid_Test
UVLG3modem
VK1_Test
Every single one upon reboot leaves me with no connection.,, I don't get what I'm doing wrong here... frustrating. Only way I can get any kind of connection after flashing radios for hours is to flash my restore, which brings me back to the edge2 network. I've tried the Good Blaze ICS newamss and the UVLG3modelfori717...n7005amss too, and while I do get a connection it's virtually the same as the existing crappy 0 to 1 bar, or none with a no-connection symbol.
Any help guys?
Anyone at all? I get weak to no.reception in most places and when I leave the city I have no.connection at all. If it was the radios then why wouldn't trying all those radios show improvement? At this rate I am considering just scrapping the whole thing and getting a phone tats locked to Fido if this is the best there is.
Is this the right forum for this?
Re: SGH-i717D Radio/Modem for Fido - help!
There is no such thing as a Fido radio. You flash a T-Mobile compatible radio (recognizes and uses the two bands/frequencies AWS), verify the baseband in phone settings is the radio you flashed, input the correct APN settings for Fido.
Things to check: your sim works with data in another phone, data is enabled in phone settings.

Thx... SIM works fine, data is enabled. Phone always says unknown under the baseband on phone settings. Pretty confident APN settings are fine, I had them confirmed with Fido. Is it just I haven't found the right modem/radio?
I tried the ones I've found most common in threads: iceblaze, KID, VK1 and even an UVDLE from an S2 thread.... still getting the same low, low signal, 0 to 2 bars with intermittent EDGE:2 signal.
Re: SGH-i717D Radio/Modem for Fido - help!
Ok, so you are sending/receiving data. But is that only using EDGE network or have you connected to 3G data network?
And if you don't have a baseband, the usual remedy is to return to stock at&t ICS rom and reflash your preferred modem.
Have you had better data strength with another device? Maybe two bars is all your location gets.

I know we are conversing privately but I'll continue the responses here in case it benefits someone else. I haven't been able to connect to a 3g data network yet.... Because my unit is an i717D (Telus), do I need to flash to the stock Telus ICS rom or do I need to use the AT&T rom?
I was using an HTC One S, same network but locked to Fido, default OS, same SIM card, and was getting perfect signal and data speeds. I can't see how a place like downtown Toronto would yield any signal issues... like you said it seems like it's a radio/modem issue.
Re: SGH-i717D Radio/Modem for Fido - help!
I hate to suggest it, but one old dependable T-Mobile compatible modem:
http://bayfiles.com/file/6FwV/WrxD5a/Blaze_4G_LB7_radio_ATTNOTE.zip
Its been modified and many have had success with it.
So I have flashed a stock Telus ICS ROM, and along with a stock Rogers radio am getting a baseband I717RUXLF4, Edge:2 signal, and even Fido under network. Getting 1-3 bars signal strength, but still no data.
I tried flashing like 5-7 ICS radios and all of them produced a 'no sim' on reboot. I had to re-flash the stock Telus ICS rom and the rogers radio to get it to read a SIM again...
Super frustrating as I feel like I'm going around in circles never solving the issue here...
Does anyone have experience with Fido modems in Toronto or Ontario? Everything I seen to find.is either for.Telus, Rogers, Wind or Bell...
Sent from my SGH-I717D using xda app-developers app
Another update for no one to read....
Tried flashing the Perfection ICS ROM... got same signal issues, installed the Rogers radio that seemed to work incrementally better with the stock Telus Rom... still floating around the issue of low signal...
There is a shockingly little amount of documentation on Fido setups here... most everything is either Bell, Rogers or Telus, with some Wind and Mobilicity.
Can ANYONE please provide me with some direction here? I think I've done my due diligence and respected the process for new people that these forums demand in terms of reading, research and such... I haven't spammed my issues anywhere else, and clearly seem to be stuck on this issue....
Ok, you need a modem that is 850/1900. at&t is 900/1900. So thats why you get 2G because in some areas you connect with a weak signal.
The Canadian stock rom and the Canadian stock modem for Rogers should work.
In network settings you may be able to select network frequencies. If so, select WCDMA only so your phone stays on 1900.
If that doesn't work, dial *#2263# and find the band selector, and select 850.

[Q] Optimus G Data on T Mobile driving me insane. Please help!

Hello all, so I recently consulted your fine website about purchasing the Optimus G to use on T Mobile here in Pittsburgh. It seemed to me that people were able to get HSPA+21 and LTE on the phone in the right circumstances, and that was good enough for me. So I bought the phone, unlocked it through cellunlocker.com and everything seemed to be going smoothly. I punched in the standard fast.tmobile.com APN address and I got 4G HSPA+ right away. I then proceeded to drive into downtown Pittsburgh, which now has T Mobile LTE, to see if it would connect. It didn't connect and stayed on HSPA. At that point I drove out of the city and went back down to EDGE and my phone no longer connected to HSPA anymore, only EDGE, until I went into my Mobile Network settings and selected the carrier directly. So I went into T Mobile to ask why my phone won't automatically connect to the most OPTIMUM speed and he couldn't figure it out. As a last ditch effort, we switched SIM cards and my phone automically jumped to LTE and his was stuck on HSPA. So hey, we figured it must be the SIM card keeping me from LTE. He gave me a new card, and it was on LTE until I left the store's broadcast radius. From then on, same story. The phone seems to pretty frequently get stuck on EDGE speeds and I contantly have to go and manually set the network to get HSPA+. What's more, I can't seem to get LTE under any circumstances. Can somebody out there please tell me what's going on? Do I have a defective phone with confused radios? Is T Mobile having a hard time syncing with my AT and T device? Do I need to do something with my APN or Mobile Network settings? Does this have anything to do with the way I unlocked the phone? Is it because the LGOG shares radios for LTE and HSPA or something that it won't default to LTE when it's around? I love absolutely everything about this phone and would like to keep it, but if it keeps behaving like this and won't even give me LTE or consistent HSPA+ then I might as well just get a crappy LG Optimus L9 that at least was designed for the network. Any insight you guys can offer would be much appreciated. Thanks so much!

Try flashing the 33-84 radio: http://www.mediafire.com/download/wec8eeext05x8ge/LTEhybrid33-84.zip
That's what I use to flash my LGOG. That's from the Nexus 4 radio thread, and from T-Mobile N4 devices. I was able to add a different APN for AT&T easily, maybe can do the same for your T-Mobile.
- Combines the latest .84 radio from T-Mobile N4 and .33 LTE support.
- The N4 Radio thread: http://forum.xda-developers.com/showthread.php?t=2087227
I see. Well seeing as I'm kind of a noob at this your post intimidates me a bit. How dangerous is it to put these N4 radios onto an LGOG? Will I risk bricking this thing or losing signal forever if I screw it up? Also, I'm assuming that the device must be rooted to do this? Also, if you think it's safe to try is there a thread or something that you can link detailed instructions for? I've never done anything like this in my life...I felt like a rebel just unlocking my phone! Thanks!

Not dangerous if you use TWRP. Just make a backup of your current stuff, and if it doesn't work can just restore. It won't hard brick your phone. And I've had it flash on more than one rom so far.
Root needed?

I see. Will the phone need to be rooted for that app to be used for the radio ROM? That's probably a silly question to ask on this website especially...but there it is.
I just got this phone and I'm loving it..came from the gs3. I was looking for a thread like this...hoping for a way to unlock the aws band..will root and flash tarp and try this tonight.

would like to know if there's any update, thank you!
I have almost exact same problem. T-mobile lte not working for me, always getting the hspa+. I went to store and asked for a replacement sim card, then bang, lte shows up with the new sim card. Right after I walked out of the store and left in about 1 minute it's gone, forever. I'm not able to pick up any lte signal anymore. When I put this sim card in my ogp, it fires up lte right away.
I have read in another post people reporting they get lte with unactivated sim card but it went right away when they activated it. Really hope someone to explain for us how this situation is happening.
Thank you for all your great work.

I couldn't edit my last post so I'm putting a new reply to add some info.
Both my og and ogp have the same apn settings. I tested them using the same sim card.
I just put another unactivated sim card in the og and surprisingly it picks up lte immediately. I don't want to activate this sim card right now so I can't tell if it would go away if I activate it. I hope this info would help a little bit.

would like to know if there's any update, thank you!
I have almost exact same problem. T-mobile lte not working for me, always getting the hspa+. I went to store and asked for a replacement sim card, then bang, lte shows up with the new sim card. Right after I walked out of the store and left in about 1 minute it's gone, forever. I'm not able to pick up any lte signal anymore. When I put this sim card in my ogp, it fires up lte right away.

Help! I have the exact same problem. I have a brand new att lg optimus g and unlocked it. Popped in the sim and bam LTE! Ran a bunch of speedtests, drove to my friends house and it switched to 4g and hasn't come back. The guy at tmobile wasn't sure. ...any help ? I'm going to root this and try flashing a new rom...maybe radio?
Seems to be an issue with this device, perhaps it's doing something to the SIM cards (who the hell knows) because mine did/does the exact same thing, and here's my particular example:
When I first got this LGOG last Sunday (8 days ago) I put my T-Mobile microSIM in it (one of the TM9190 series SIM cards) and got LTE off the bat without any issues. I kept the stock ROM on here for the first day or so and never had any issues and then I got into doing the typical root/unlock bootloader/install recovery/backup stock ROM/flash custom ROM/etc routine and even after that I was still able to get LTE working almost immediately.
A few days ago I noticed that the LTE wasn't being picked up, and it hasn't since. I've flashed several radios for testing (.33, .48, .33-.84 hybrid, etc) and the ones that are LTE ready still didn't get LTE so I just flashed the whole thing back to complete JB stock (JZO54K, the last available LG build) and even that didn't help - I've yet to see LTE show up in any respect at all with that SIM card.
Now the interesting part:
I have another microSIM that had prepaid service a few months back, bought it at the same time as the one I use for my primary service - they were on sale from T-Mobile online for $.99 each so I got two and kept the other one around just to have it.
In spite of all the flashing I've done in the past few days, with like 5 ROMs tested, a kernel or two, and maybe 7 flashes back to pure stock using LGNPST and the LGE970AT-01-V20j-310-410-MAR-08-2013 ROM (the stock one), after all that flashing torture I put this LGOG through, as soon as I put that other SIM card in it - which is not active at this time - and powered up the phone I got an LTE signal right off the bat without a problem. Had already made the APN changes to fast.t-mobile.com so they just kicked right in and wham, 4G LTE right there on the status bar.
And yes, the SIM cards are the same "series" (?!?!) with TM9190 imprinted on both of them - they also have the same code on the front side (620048) and their serial numbers are just a few digits off in sequence - like I said, I bought both of them with the same order so, it stands to reason they'd be from the same batch.
Loaded a few web pages on the T-Mobile prepaid billing site (it's what comes up when you insert a prepaid already activated but not presently in use SIM, very limited but it does work), checked the system stats, everything showed me I was connected to T-Mobile with their LTE service, this phone, and that other SIM card including the status bar icon being the traditional 4G LTE one (big 4, little G, little LTE under it).
Then I rebooted the phone and that was that, the LTE capability just up and vanished like a fart in the wind, and I've done most everything that I could do - including reading a few hundred posts in two dozen threads - to get it functional again and it just doesn't work anymore.
I suppose it's not a big deal to me since T-Mobile's HSPA+ is fine with me, I regularly pull in 10-15Mbps on a speed test in various locations (was out earlier today testing stuff in the eastern parts of Vegas), but I am somewhat pissed that I am unable to get that LTE functionality working again.
Tried:
- a complete stock flash, several times, of the AT&T JB ROM, no dice
- all the currently available LTE-capable radios, no dice
- an AT&T SIM but it's not provisioned so it doesn't work at all (T-Mobile doesn't do that, hrmmm... their SIM cards work months later even after the number has been assigned to another customer, go figure)
- all the hidden menu options (3854#*970#, WCDMA automatic, tried forcing LTE only, several other things), no dice
- tried manually setting LTE only with *#*#4636#*#* using custom ROMs, no dice
- adding the LTE enabling lines to build.prop, no dice
Nothing works, so I'm only left to conclude that either a) T-Mobile is doing something funky (highly unlikely), b) something is borked with the phone (potentially true), or maybe c) the phone is doing something to the SIM cards after a reboot or any change in the network mode from LTE to anything else (leaning towards this possibility more).
I can't explain it, I can't figure it out, and I can't get LTE working anymore but as I said, the HSPA+ is enough for me as here at home the LTE signal is somewhat weak (1-2 bars at best whereas HSPA+ pulls in 5 bars and a -61dB signal almost constantly).
I wish I could figure it out because I'd like to do more testing with LTE enabled but apparently once LTE gets disabled for whatever reason after having it actually working, not once but twice now it just dies and never becomes possible again.
Stranger things I suppose...
If anyone does ever figure this fiasco out, post whatever solution you came up with or discovered so the rest of us can give it a shot as well 'cause I'd love to be able to enable LTE if I so chose. This is pretty frustrating in the long run - if it never ever worked at all that would be one thing, but having it work then suddenly just disappear never to work the same again, that's just pooched.
Slightly off-topic, but how's the battery life compared to AT&T? Or, in general, is it okay?

Thanks for posting your experiences. I've had the exact same problem, though I've never been able to get LTE working at all with my phone. I'm planning on taking a trip to a T-Mobile location within the next few days and see what they can do. Maybe they'll let me try putting my SIM in some of their display phones to see if I can get an LTE connection. Then at least I could probably rule out the SIM as the problem.

Make sure that your phone has the fast.t-mobile.com APN info in place (just create a new APN with that info if needed, maybe call it T-Mobile LTE and see what happens. My guess is if they put a new unused SIM into your phone it'll most likely kick into 4G LTE right from the start (as long as the APN is in place) and then at some point it'll switch to HSPA+ and it'll never go back like it has for those of us that have noticed it.
Who knows... it's probably just one of those things.

Could be...I've always had my settings on T-Mobile LTE, and I even called T-Mobile and confirmed every field in the settings with them. When I explained that I still couldn't get LTE, they had no other solution for me. The lady on the line didn't even know that LTE was faster than HSPA+, so I wasn't exactly expecting any sort of resolution. I think the reps in-store will be more suited to this type of issue.

[Q] Straight Talk Help

I have an unlocked i717 that I've been using on tmobile for the past 2 years but I just switched to Straight talk so that I can use At&t's network which is much better in my area. I'm running stock 4.1.2 and I've tried several At&t Modems. I have the correct att APN but I still don't get any service. Under select networks I can't select anything. Any tips for modems/rom combinations that work on straight talk?
So after some fiddling I did manage to get connected so now I can send texts but I still don't have any data access, not even edge. I do have the correct APN.
What type of "fiddeling" did you do? You seem sure of the APN, I have been using ST for a long while and use the latest APN from their support website.
Heres the funny thing, I think I've got it all working. What I did: nothing. I let is sit overnight, after the Straight talk website said my number transfer had completed, and magically data was working in the morning. So I guess I'm all good.
I'm using the UCMD3 modem with straight talk and get 4G coverage in most nearby areas.
Same situation here...although I have to travel to "reach" any 4G!

Verizon S4 on Tmobile network. OS 5.0.1, signal issues

Bought a refurb SCH-I545 Verizon to run on Tmobile network. Created a new APN and have things working but signal is rather poor. Seems to hunt around a LOT from no signal to full signal and data 2G to 4GLTE. Not consistent at all. Many calls being missed and sometimes trying to call out, I have no signal. Tmobile is out of ideas. I think I have most settings right but something is either wrong with the phone or a setting is off.
Can anyone confirm?
I am considering rooting the phone to delete all the bloatware? I am not sure if the boot loader will be opened? I would not mind losing the Verizon boot screen and the "sim is not verizon" BS....
At first, tmobile thought the phone did not support 1,9ghz but all documents I can find say it is fully supported. Do I need some radio apps?

Have you tried asking in the T-Mobile S4 help forum?
If not, try posting your question here:

You'll probably get better results.
Good luck!
