I have an i9515 black edition from the UAE but I'm using it in South Africa. When I first got the phone, 3G worked. After an OTA, it's stuck on 2G. I've factory reset a few times and even flashed a UK version of Lollipop on it. Still no luck. Is there any way I can get 3G/4G working on it again? Even if I have to root it.
Hello gc180,
please check you APN-Settings.

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

Hi Guys,
I purchased a Samsung s4 i337ucufnc1 in usa. Have the phone unlocked and am now in South Africa. I have tried to root it and think it is but the wifi is not working. Initially the data was not working and wifi was but after I believe rooting and countless factory resets. It has switched the other way data works and wifi says a security setting will not allow updates, the operating software is the 4.3 version.
I have not found many codes for the samsung s4 i337ucufnc1
how do i get the wifi to work again. Please
Dial *#1234# and attach what appears.

Try to reflash stock rom with odin. Maybe the modem files got corrupted.
Ok just released the phone is not rooted, will this process still work?
Hi guys
My phone was rooted but never flashed a ROM on it. Today I updated my phone to Lollipop through Kies Mac. After that my signal is not there. When I reboot the phone I get signal for few seconds then it gets lost again. Also phone never saves my Wi-fi connections.
I did reset my phone but still the same.
It was locked to Vodafone and I unlocked it in Vodafone shop when I first bought it do you think anything related to that?
How can I downgrade to KitKat or get my signal working?
Same here. Do any of you guys know how to solve this issue?

Please use the search function of this site and google, don't be lazy. There is a thread about downgrading . Also try flashing lollipop modem/bootloader, for this visit any of the TouchWiz Lollipop rom threads (like the one in my signature) most of them talk about flashing modems and bls.
Hi ,
I have a unlokced at&t s7 galaxy edge and I was using it till yesterday on Tmobile network
every thing was working fine till this andriod 7/ Nougat update came in.
As everybody else I was very excited and let the phone go thru the udpate, everything went fine and I got andriod 7.
However after the update for some reason only mobile data ( I can make/receive calls) is not working on Tmobile network.
1. put the SIM into another phone to check there is no problem with the SIM/network outage. We found that there is no problem with sim/account and data/voice everything works exactly as it is supposed to work with another phone
2. I rechecked all the settings/apn/data/ etc many times on unlocked galaxy s7 edge phone but data is not working. I still see 4g/4g lte icon but I don't get the data. we tried manual search/resetting of network as well
4. I have put my brothers AT&T sim in on same unlocked galaxy s7 edge phone and data works fine.
can you please help me, advise what are my options now ?

What firmware were you running when you installed the OTA update? You may wanna try manually installing the full T-Mobile or AT&T Nougat firmware with Odin, just to make sure everything matches up?
Edit: hmm, if your brother's sim works in the phone, then everything might be ok. But still, installing the full firmware by hand won't hurt. This is weird tho lol
Ok, cool. I will search for it and try that out and post my results. Thank you!

I tried something new and I have interesting results.
I installed a Firmware U, it is a version of android 7. I installed it by odin and everything well without problems. When I restarted I put the SIM and it told me that I had to restart to configure the options of my operator. It restarted without problem and to my surprise it CONTINUES without Signal. In '' Access Point Name '' the APN of my operator's MMS has been created ONLY and AUTOMATICALLY. I did not set it up, it came out alone.
I still do not understand what problem this phone has. There are several people reporting similar problems with the upgrade to Oreo even in other S7 EDGE models.
Any ideas?????
