Canadian ROM only shows 4G signal icon (with LTE speeds) - why ? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi all,
I recently bought a Galaxy S4 337M that was rooted and loaded with a custom ROM. I decided to go back to stock so went to sammobile.net and got the latest rogers firmware for my galaxy S4 (which they said was 4.3).
I loaded with ODIN, all went well, rebooted stock, but the max signal icon I can get now is 4G (even though I used speedtest and am getting close to LTE download speeds I think). Any idea why my LTE is gone ? Did I download the wrong ROM ?
I also noticed that none of the APN settings were there and no rogers apps were installed either. Makes me wonder if it was indeed a stock rogers rom after all.
Another strange thing is that it shows me a bell canada navigator update is available in the google play store, yet its not even on my phone. Regardless, even if its a Bell ROM by some chance, Bell Canada has LTE as well, so I am confused.
Btw I used the standard ltemobile APN settings that I always use on all my phones to get LTE (that always work)....
Any help or suggestions would be really appreciated, thanks so much !!!
My iPhone shows LTE using the same SIM...
PS. If I do need to get an original Rogers ROM, is sammmobile not the best place lol ? Any other places to go??

I believe that all I337M uses that same firmware but you need a CSC changer to make it change to your carrier as they don't release the specific ones with the carrier apps.
Search "Samsung CSC" in the play store and you should get one.

Thanks for the reply.
Seems I need root - which I deleted when doing a factory restore.
The strange thing is that it was supposed to be a rogers based firmware that I downloaded and flashed.
Maybe something went wrong in the flash.
Will try again.
And check out the CSC

i have a bell i337m and i have the same issue when flashing from a "custom rom to stock" and i have to flash the firmware using odin a second time and than i get my LTE icon enstead of the 4G icon, sounds weird and i can't explain why it takes 2 flashes to get it to show up proper, but it does.
i also have the problem with missing phone vendor apps, the second flash also makes these show up too.
also another thing i noted about my phone is if i don't root and install recovery to wipe, odin will dirty flash my roms, even though odin is supposed to wipe it isn't.
i've tested this to no ends, the results are 100% the same everytime.

After flashing the stock Rom, go back into stock recovery and wipe data and cache, then reboot that should fix it. To fix your csc issue there is a way to do it by dialling a number on your dialpad which includes your imei number then you choose a specific code. Search for it, google

Thanks so much for the replies and help.
I wiped the rom just for fun and rebooted and noticed that its actuality a BELL ROM (all stock BELL apps etc), but when I entered my rogers APN settings it still only showed H+, maybe due to network differences. It's frustrating because I specifically selected a Rogers S4 ROM from Sammobile.net. Any idea where I can get a stock rogers ROM for s4? Also do you think this may have affected my 4G/LTE issue ??
Either way, I will definitely flash the correct ROM twice, and then go back into stock recovery to to wipe data and cache.
Thanks again for all your help

follow this guide, http://www.droidviews.com/how-to-change-csc-in-samsung-galaxy-phones/ real easy, itll put you back to a rogers rom, all the firmwares on sammobile are BELL ROMS. you have to change the CSC yourself.

THAT WORKED
Thanks so much !!!

[Q] Note 3 N900W8 Not letting me choose network

I've been trying to fix since installing the new update at 2pm (PST) today. Finally decided to post a question here hoping someone more knowledgeable can help me fix it.
I bought the phone and it was locked to Bell so I bought a code and was using it on Fido. I flashed the Telcel 4.4.2 update and after I flashed all the files it worked (I tried not flashing modem). When it started I got a screen that said "Network Lock" with only a dismiss button (i.e. nowhere to put re-input my unlock code). If I click it 3 times it lets me into device. In the status bar it says "Invalid SIM card" "Network locked SIM card inserted". When I try to make a call I get "Not registered on network"
I've also tried flashing my old modem.bin via ODIN but that just cause the phone to boot and vibrate a bunch. I was able to get into settings but no option for Network Operator or APN.
The network doesn't work but WiFi and everything else does. So I rooted using the new N9005 root. Added APN settings, and of course, looked for network operators. Fido doesn't show up but all other carriers do (except Chatr).
I'm in the same situation as you are but which new N9005 root are you talking about? I'm on Rogers so if I can use that to get my signal back, that would be awesome.

I got the autoroot installed and working fine. It says invalid SIM.
Previously, I had installed the firmware without flashing the CSC and I don't remember having sim lock issues then (as the Telcel specific files are not flashed) however you have to deal with the Samsung keyboard repeatedly crashing, so you have to find a way around it.
So my suggestion is reflash without the CSC file and brainstorm a way to put another keyboard on it without needing to input anything first (so Google Play is a no-go), probably side load a keyboard apk through ADB or something. Going to give it a shot.
---
The keyboard idea worked fine. Unfortunately I did still get the region/sim lock stuff because everywhere outside of Canada seems to have it turned on and the ROM defaults to tmobile without the CSC apparently. I've decided to bite the bullet and just pay for an unlock as I was planning to do so anyways.
---
And that worked until I rebooted and it asked for a SIM unlock code... well... damn. I'm just going to try to flash a rom with region/sim locking removed. Ugh.
Looks like we can fix this by downgrading or creating our own Rogers files: http://forum.xda-developers.com/showthread.php?t=2608178&page=54
I have the CSC and modem.bin. Tested and working (remember, I flashed PIT as said here http://forum.xda-developers.com/showpost.php?p=49512809)
https://www.mediafire.com/?yjdgd4j8s72bo46
I rolled my own too. Working fine.

Same thing was happening to me. Just follow the instructions in my previous post.

constant data issues fed up please help!! , Rogers but with Bell bloat??

Okay here's the problem. I had cm11 had data issues, such as very weak signals. Switched to another Rom, same problem. So I decided to flash back to stock. Downloaded all the files, on sammobile rwc is listed as Rogers. But it has the bell bloat, and now my signal only says 4g not lte, verified apn settings. Have my brothers s4 and he's got lte
LTE and 4G are the same thing mate..

Hi,
The first thing would be to check your CSC and modem firmware. Use Phone INFO ★Samsung★ app to get all major info about the phone. It is important to know when you are going to flash another stock firmware.
I had issues last week with data and it was caused by bad CSC/modem. Flashed everything back to stock with official firmwares from SamMobile and it fixed my issues. After that, I was able to flash my custom ROM and everything is smooth sailing since then.
Let me know if you require more help.

[Q] Virgin Mobile Stock ROM?

I have a Virgin Mobile S5 - and was thinking of rooting it and a recovery also.
My ROM G900PVPU1ANE5
I see in the Sprint S5 area it will work (I did similar with my VM S II)
Anyway; is there a way to get a backup of my Stock ROM? - There are no V.M. ROMS in the lists (or anywhere I look for that matter) except Canada and it is different.
I wondered about something like Rickys Rom Kitchen to get a ROM BU - I will read that post and see if I can make any sence of it all.
I ask, just in case something was to happen - and without a Stock Virgin Mobile ROM I could not get it back to stock.
FWIIW - My S5 does not seem to have anything Knox on it -
Edit - when installing recovery - it reported knox
There are dozens of firmware repositories, not to mention a links to a lot of firmware on this site. It's difficult to believe that you did a decent search and couldn't find any stock firmware for your carrier.
Tell us what sites you have checked and what keywords you searched with and no doubt someone will be able to point out a site you missed.

I searched with many terms;
Galaxy S5 ROMS
Galaxy S5 Firmware
Virgin Mobile Galaxy S5 ROMS
G900PVPU1ANE5 <-- Sprint has same number (But theirs is branded Sprint and will likely show a Sprint Splash on boot)
(As I had this same type thing with my Galaxy S II from Virgin Mobile a good while ago and had to use a Sprint ROM)
I will be a VERY happy camper, if someone can find a site I missed! (With my V.M. ROM/Firmware on it)
Since you gave details of actually having searched (most people claim they have, but really didn't), I did some digging for you.
The reason that you are having difficulty finding stock Virgin (US) firmware is because Virgin US is a Sprint MVNO (Virtual Network Operator) that is wholly owned by Sprint since 2009. This means that Virgin US uses the Sprint network and is supported by Sprint vis a vis the Virgin US offices in New Jersey.
As a MNVO, Virgin US uses the same S5 variant as Sprint, the same MCC and the same firmware. Only the CSC, MNC and APN info (and a few branded apps) vary. Moreover, since Sprint is using multi-CSC firmware, the firmware is often tagged as SPR (Sprint) or Unknown when it actually is the original, stock firmware for Sprint, Virgin US and Boost (another Sprint MVNO).
So the original firmware for your phone is in fact the Sprint version. If your phone currently has Virgin US firmware on it, then installing the multi-CSC firmware should retain your correct CSC. If it was me, I'd just do a quick check afterwards.. your CSC should obstensibly be VMU.
SPR = Sprint
VMU = Virgin US
BST = Boost Mobile
.
Tkx for the details ffft
I may just go ahead and root it - and put a custom recovery on also.
I rarely have had issues with my cell phones (Warranty that is)
I just would feel better if I could restore it.
I do not know much at all about Cell Phones and the terminology (I looked up a few of them you have here)
I just found a way to check these (by *#1234# ) and came up with:
AP G900PVPU1ANE5
CP G900PVPU1ANE5
CSC G900PSPT1ANE5
I do not know what the AP and CP are but at least I can check them
AP firmware version
CP radio version
CSC sales code (region or carrier code)
The long CSC is a bit cryptic. But you can use an app like Phone Info to get the more commonly used three character code. Or if you are rooted, you could look at the build.prop file.
.
OK I installed PhilZ CWM Advanced Touch (Recovery) without root.
Then I did a full back up
and also found a "Clone ROM" and did that also
(it makes an update.zip)
Now I "should" be able to root - and if something happens flash the ROM I made with PhilZ's CWM
** See below Post - it does not stick when not rooted (Unless I did something wrong)
OK I rooted (CF auto root)
And I still show the Virgin Mobile splash
I did have some problem with PhilzCWM until I rooted - it would not "stay" there
I could run Odin and install it and one time boot to it and do back ups
But next boot it was gone
After I rooted - I re installed it - and it "stuck"

All normal behaviour.
Glad you got there. Everything runs better with root The objection to your custom recovery before you rooted was no doubt Knox seeing it as an unauthorized change.

Great thread
Really loving your thread. I just came from a broken s4 to Virgin mobile s5. I understand Odin/root/rom installs/returning to factory stock to update etc...
Obviously Virgin Mobile s5 threads are limited here and would like to work together and update each other.
I got root without tripping knox "not cf autoroot method" but "towelroot" method.
First thing we need to work on is getting the .tar file for odin to return to factory stock if something happens.
With all the updates that will probebly be rolling in soon im reluctant to install a custom recovery because you can't update it "over the air."
Second thing is i have no idea to get a official thread going.
Other thought
I orginally came from a Virgin Mobile Evo 4g 3D and the ROMs was aroma based. There was a specific setting if you had a sprint or virgin mobile phone during the installation. I believe it's about having to change APN settings and whatnot. Need to research this Sprint/Virgin Mobile/ROM duo more and what exactly needs to be changed.
Im confident the Sprint ROM itself is good. Just particular settings, one for example, the APN needs to be switched back to whatever Virgin Mobile is.
Interesting tid-bit the Phone info app shows my Samsung s/n as 00000000000 now
No Country of Origin
Knox Warr = 0x1 (Does that mean knox is tripped)?
Product Code: Not Active
I noticed that there does not seem to be a s/n on it - except for the MEID (hex and dec) and a ICC ID
I updated with Kies 3 to G900PVPU1ANK4
This (natrually) made my Virgin Moblie S5 Stock again.
Then did both CF auto root and PhilZ CWM Advanced Touch (Recovery)
And it all seems to work fine again.
HELP PLS

I need your help desperately! I just got my virgin mobile s5 yesterday and I am new to running Custom ROMs. I rooted it and successfully installed PhilZ CWM Advanced Touch. From here I think I skipped a step in CWM to make a proper backup (yeah I'm that noob). Well I successfully installed Slimkat and got it to run on my phone, but I couldn't configure the APN properly on virgin mobile after countless installations of different "universal fixes" for the vmu apn. Now I can't get it back to the stock firmware! I am downloading the sprint firmware right now, specifically the G900PVPU1ANE5_G900PSPT1ANE5_SPR.zip. I couldn't find virgin mobile stock firmware. Do you think it will work if I flash it on there? If not, do you happen to have a backup to the G900P virgin mobile version I could flash? I just need service again.

Okay I'll still try a few things. Do you have any backups or know of any roms that for sure work with the virgin mobile data service? I am just running into a bunch of issues with slimkat and if you knew a rom that was compatible with Virgin Mobile and this model of s5 I could have mobile service again! especially if you knew the steps how to do it

Ahh yes I also took these steps to root and download a custom recovery on my phone, which I succeeded in doing. Perhaps I haven't made my problem clear. I have PhilZ installed and everything along with a rooted phone. I am currently running Slimkat but I do not have any mobile service so the phone is useless at the moment. My issue is is that I have no ROM backed up. And look, I'm sorry to pester you like this but at this point I would honestly offer you monetary incentive if you help me resolve this. I'm pretty desperate :silly: I saved up for a long time for this phone and I would really like to use its cellular functions. What ROM do you currently use on your phone and what steps did you take to get mobile service working on it? Thank you very much for your time

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.

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?

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
I am a member because the owner hates the Iphone and I respect that
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......

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!

The problem is the APN and you can not modify it. Contact your carrier and see if they can assist.

ehrn i purchased the phone it was perfect. connecting internet was showing 4g.. but when i installed this original Verizon rom it became difficult.. now i am unable to root and install custom recovery... please guide me to root and install custom recovery TWRP and i want to install custim rom.. please help
@dipankar.c2bs
You might look into getting your CSC "sales_code" changed. I'm not sure if that is entirely the problem, but it is likely related. Even the USA Verizon ROMs come preloaded with databases that are used to provide custom parameters for a variety of carriers and locations world-wide. (See the file /system/csc/imsprofile.xml for example) I suspect the way this information is actually used is through the "sales_code" CSC value, but I'm not 100% sure of that.
I'm guessing you want "INS" or "INU" instead of VZW
What you currently have:
Code:
getprop | grep -i csc
If your handset is supported by Airtel, one of their technicians will probably know how to do the CSC change, possibly without even rooting the phone.
If it not supported, they probably will be under orders of their employer not to help you at all. But, is is easier for them to give you advice face-to-face, rather than over the telephone (subject to monitoring), if that is possible.
A question to ask - a form of social engineering - is this: "do you know of someone in the area that can help me for a small fee?"
[EDIT]
There is one other possibility for a non-rooted phone. I really don't know if this would work (I am speculating here), but the basic idea is to apply a CSC for a closely related device Model (a SM-N90???? Qualcomm model, hopefully for CDMA/LTE) that is for your country and carrier on top of your existing ROM using Odin. Get the CSC file from Sammobile, and:
- wipe the entire phone using the stock recovery. (You can remove the external SD card first if you like)
- boot the phone, shut down, boot into stock recovery.
- wipe the entire phone again in the stock recovery
- boot into Odin and flash the CSC in the CSC slot.
- boot the phone; do a minimal configuration and see if you have the service you want.
Note that @donc113 s advice given above is the right place to start: ask your service (Airtel) to help you before you try anything yourself.
good luck.
when i purchase it was good... there was 4g indicator also.. no verizon boot screen.. but now it dont works..

One of your friends who installed the stock ROM apparently didn't understand the consequences of what he did. Stock ROMs set the APN for Verizon. Did this friend happen to make a backup before he did the ROM switch?

Knox?
