Hello Xda
I recently unlocked my device with the regon away apk. all went well, downgraded to mf3 modem and unlocked, however after unlock, all i get is edge internet, no lte or H+. I think i tinkered with the utms and set it to gsm only before unlocking, i dont know if thats whats casuing the issue but please someone help.
Try reflashing your modem and moduels? If worst comes to worst reflash your firmware. Once you sim unlock it wont go away even if you reflash firmwares via odin.

Hey guys I'm looking for advice with my new Telus locked phone. I've tried the unlock menu method South the latest and even downgraded firmware. Every time it is still locked when I boot up.
Had the same issue with my s2 previously and resolved it by flashing a us carriers older stock firmware and modem then unlocking it then restoring back the Canadian one.
what I've read the bootloader complicated things with this phone. Can I change to old att modems and firmware? It seems only Odin ones exist and I don't want to do something stupid. I don't want to spend 45 on a code as I understand it won't work after trying the menu method. Any ideas or do I have to pay for the gsmusb method.
I ended up just doing the fast gsm usb unlock for $15.
Ok, I'm going to try to make a long story short, i hope that i've posted in the correct forum, I've been scouring this forum and others but nothing I've found has quite fixed my issue.
Got my S4 locked to Bell in Canada. Heard it was really easy to unlock [service menu *#0011# method] but once I got to Indonesia [for travel] expecting to be able to use my phone I found that the service menu was no longer available. Ok, no problem, there must be other ways;
I ended up paying for an unlock code from a site, it didn't work. In fact, immediately after I press 'unlock' it would say 'network unlock unsuccessful'.
I thought they gave me a faulty code but when the code I bought FROM Bell was the exact same one, and had the exact same problem I figured it was likely 'region locked'
I ended up flashing a stock rom with odin, one from a weird unlocking site, and eventually I got it working. The only problem was that whenever I'd go into screen lock I'd lose reception and have to airplane mode on and off to get it again.
After Indonesia I went to Turkey, was unable to connect at all with one of their service providers, but had no problems with Vodafone. I think this may have been a side effect of regionlock away app, I needed to use that as well.
Once I got back to Canada I went custom recovery with cwm and flashed Cyanogenmod. This was fine, no reception problems, 10.2 - 11 was all good.
NOW I am in Poland, and getting the same problem I had in the first place. Whatever Cyanogenmod did, re-locked my device, in some way, I'm guessing.
I'm now rooted, with TWP recovery, running Android 4.4.4 Dave GPE rom, and would REALLY like to be able to use my Polish sim card with this fantastic setup. Chainfire's regionlock away app does not work, gives me a CSC error message. My phone now says it's an i9505 instead of i337m
Anything I have overlooked? Any way I can get this fully unlocked and working the way I want it to?
*NOTE* I can't access *#0011# service menu, even though I flashed [i think] stock dialer.
You are not in the correct section

I can help you a little though. If the unlocking methodes fail, then it's usually because you don't have an older modem. You need to look for the modem you should flash in order for it to work. Afterwards you can flash the modem again you are on now. If you can't find it, just flash an old modem and try.
I find it hard to believe that Cyanogenmod could have caused this though.
Cool, that will be my next phase of attack. I appreciate the redirect and thoughts (Y)
Before you judge me by saying how i'm posting something thats done before, it hasn't, I've searched everywhere no methods work
Please, someone help me I've been at this for 4 days now and maybe just 15 hours of sleep :crying:.
The phone I have right now is the SGH-i337m Galaxy s4 running NC1 with MDJ modem (Kitkat 4.4.2) Does not detect sim, it says "No sim available".
I'm not exactly sure if the phone is from Bell but the phone use to be running fine on my old rogers sim card until I updated to their new ShareTap Sim.
With the ShareTap Sim the phone doesn't detect my sim anymore. So I tried my Share Tap Sim in another unlocked phone (Galaxy note 3) it worked fine.
Then I tried a Virgin mobile sim card on the S4 and it detected it and worked fine also. So then I tried to unlock it by flashing it with many different methods:
1. I tried flashing a older version of Bell 4.2.2 but it bricked my phone ( I already unbricked it back to 4.4.2)
2. I tried flashing the MDJ modem but it doesn't show the hidden menu.
3. I tried flashing ATT modem to try it but that also bricked my phone.
4. I tried to use the AWS tutorial shown here
5. I tried the regionlock away tutorial here in the third method (RegionlockAway doesnt do anything to my phone)
6. I pulled the modem.bin from the TAR file from sammobile of Bell's 4.2.2. But it still doesn't show the hidden menu! It's the MDJ modem but it still doesn't work!
I'm not sure whats wrong with my phone. When I put the Virgin mobile sim card in there it only shows Telus, EXT and Virgin Sim networks available not the whole spectrum which is what is supposed to happen with the 337_aws.qcn file from the AWS tutorial. Then when I flash MDJ modem from bell or the one from this dropbox link: https://www.dropbox.com/s/2m3id2cx4l...37MVLUAMDJ.zip
It still doesn't show my secret menu.
The secret menu I'm trying to access is the *#0011# but if that didn't work I also tried the *#9090# It still doesn't show the secret menu. So what do I do now? Please Help!
Thanks for reading!
Sorry to hear that, but you are in the same situation i was, the phone was probably sim-unlocked by Box Software, like Octopus or Z3X Boxes as i did, the phone won't recognize some sim cards by unknown reasons, there is no fix avaliable for this as i changed imei, tried different NVM from other phone & even replacing sim card reader. i finally sold it & got myself a i337m unlocked via code.
Edit:
forgot to mention, My SIM stopped being recognized when i upgraded it to a newer LTE version
Kind regards.
Have you tried stock NC1 with the included modem? If the device is unlocked, you might have better success with SIM recognition. In my case, my device was not unlocked, so I Odin flashed stock Telus MDJ, then rooted with CF-Auto-Root, unlocked with RegionlockAway (KNOX tripped), and applied the AWS Mod.
Then I flashed stock NC1 with the incl. modem (root gone), and managed to get Rogers LTE and Wind H+ on the Telus device. From there, I OTA updated, and rooted with CF-Auto-Root, flashed TWRP, and worked my way to 5.0.1. Trust me I know how frustrating this can be, but thanks to this forum, there was a solution. Here's what worked for me (link). Good luck.
Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?
Wrong forum. Try http://forum.xda-developers.com/galaxy-s4-att as you're likely to get more relevant replies there.
So i successfully rooted my unlocked att version of the s5e.
everything was great until i popped my sim back in and the device wouldnt connect to att's network
im assuming thats it because the base os firmware was CDMA and not GSM so the bands i needed werent available.
i flashed another os i think its tmobile. no oem unlocking feature in the developer mode. im trying the trick to unlock it with not luck.
anyone have any advice?
So i figured something out. as ive been trying to flash different firmware.
it is now rejecting ALL Cdma firmware. and will only accept GSM firmware.
So after trying everything i finally just started trying every version of odin i could find. and finally found one that worked lol

Perhaps it will be helpful to others. Could you elaborate?
ok to start off i followed the steps from another post https://forum.xda-developers.com/t/...908u1-versions.4400511/page-155#post-88289615
i didnt have lte data and i needed it; so i reflashed ATT's firmware. when i went to try to load the us cellular firmware again. it would fail at system. everytime. after flashing lots of firmwares to get it to oem unlock, i finally discovered that. it was only failing on any firmware that was CDMA related.
spent an entire day and had almost given up.
then i started trying to flash the us cellular with every odin version i could find. and finally odin v3.13.1 raymond patched odin worked.
but after finally getting it to root again. i still have to figure out a way to get lte data on ATT sim
and i now have data with AT&T by following these APN instructions from AT&T
