[AT&T Samsung Galaxy S 4 General] Solace50:
im sure fred will correct me if im wrong but theres no difference between any of the modems other then what bands they operate on "int model vs US". the modems are all nearly identical in every way exception of the aws enabled band. its more or or less will the modem brick the device or just not gain a connection if the provider say somehow puts in a device check to see what model the modem is operating on since they are labeled differently. i do recall flashing a g2x with a tmobile modem in the past though that could have been identical to wind. as well.
[AT&T Samsung Galaxy S 4 General] 01jayss:
can confirmed that this worked on my Fido/Rogers GS4 with MK6 modem/baseband on Android 4.3.

Note, however, that I had to use *#0808# instead of *#7264# as in OP. Also had to install Kies to get my computer to recognize my GS4.
[AT&T Samsung Galaxy S 4 General] Goliath27:
That's weird, I can't seem to use any of those codes anymore.

Has anything changed since the new roms have rolled out? I'm on a 4.4.2 GE build and wondering if that's why. Can't access the phoneutil menu

Also, anyone know how I can check to see what modem I have installed? I'm not sure if my recent rom applied a modem as well.
[AT&T Samsung Galaxy S 4 General] ookiller:
I have tried flashing US Modems before and they do not work(invalid Sim).
[AT&T Samsung Galaxy S 4 General] SamdungSpambot:
do you mean it survived the OTA update? or that you updated to 4.3 then ran the mod?
[AT&T Samsung Galaxy S 4 General] saqi4you:
i have S4 i337m 4.3 is it work for this ?

i have done S4 i337m 4.2 but i dont know is it same ???
[AT&T Samsung Galaxy S 4 General] topgun303:
Well I have att s4 4.3 mk2 build rooted and safestrap 3.71. So fot the mod to work in OP I had to flash MF3 modem and then installed phoneutility apk. Used code *#0808# then just back up your current modem and Install the one in op.
[AT&T Samsung Galaxy S 4 General] Solace50:
thats using 4.2.2, everyone should not be posting there on 4.3 unless its the modem specifically being used. 4.2.2 works fine on majority of 4.3 roms and actually works on kitkat as well (not sure if datas bugged) the 3g indicator keeps switching between home/3g. not sure if thats a cm issue or its due to the 4.2.2 baseband. i was still able to call my voicemail for a solid 15 minutes without dropping.

in short you can flash the 4.3 roms or do you what you did and flash the 4.2.2 modem then mod it again if you did a full update.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I'm rooted with Loki (MDL bootloader, never took an OTA). Flashed MK2, mod didn't work anymore. Went back to MF3, and I'm running Wicked 9.1 (Android 4.3) and it works fine (both the mod and the modem itself with the 4.3 ROM). MF3 is the last i337 modem that will work with the mod, and also happens to work with 4.3 ROMs.
[AT&T Samsung Galaxy S 4 General] Solace50:
i pushed winds 4.3 ota to my phone then the BB after since it failed to flash the first time. seems to work fine. ill try tmobile in a bit, i dont see why on a unlocked phone there should be any issues.
[AT&T Samsung Galaxy S 4 General] ookiller:
Winds 4.3 ota to my phone then the BB? Sorry I don't understand..
[AT&T Samsung Galaxy S 4 General] Solace50:
odin wont successfully flash OTA basebands the first time, you need to manually flash it after from my experience. just try using winds MK5 BB first, theres no reason to use tmobiles.
[AT&T Samsung Galaxy S 4 General] ookiller:
I am currently using MK5, but still doesnt fix my problem with the Rom I'm trying to use. Anyways I'm currently running another rom without any problems, so guess I'll stick with this for now.
[AT&T Samsung Galaxy S 4 General] Solace50:
then its probably the rom, basebands just handle connectivity, invalid sim errors are usually related other things i suggest you try to figure out why first because i dont believe a tmobile bb will solve your issues.

---------- Post added at 10:27 AM ---------- Previous post was at 10:08 AM ----------

out of curiosity which modem did you flash... i cant push tmobiles to my device. only wind/rogers probably other canadian ones. the file probably checks the hwid to see if its a us/cnd model i guess.
[AT&T Samsung Galaxy S 4 General] ookiller:
I've never had a problem flashing the Modems, use Odin mobile. Im using modem_CWM_I337MVLUAMK6.zip{11/26/2013}(Canada) found here http://xdaforums.com/showthread.php?t=2324667&highlight=how+do+you+back+up+modem
[AT&T Samsung Galaxy S 4 General] Solace50:
you could try flashing the tmobile MK2 in the future, winds MK5 works fine on my i337m. left the phone on voicemail for a an hour with a script cycling through menus. even the MG1 modded modem did work on 4.4.2 by CM, the only times i had issues was trying out i think golden eyes rom of which actually had connectivity issues due to the incompatibility and specifically stated to have a 4.3 modem (i just tried anyways).

as for the mod yea MF3/MG1 are the final 4.2.2 bins that it works on. as for 4.3 i only think you can mod the rogers/fido/telus/whatever else is on there network once someone gets the new offsets to be changed. i checked the file sizes of the bins and the only matching ones were rogers/tmobile, wind was off by 6kb so it might work assuming the addresses match. all of this is quite ill-relevant for canadians since they can just flash the wind/mobilicity bb anyways.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can't do that on the AT&T S4. It has a locked bootloader. The Loki exploit works around it.
[AT&T Samsung Galaxy S 4 General] riversight:
I've read about half of this thread, wish I wasn't such a noob - but I think I understand the gist of it. So, will I still be able to follow just the instructions of the OP to enable an ATT i337 to work on Mobilicity (both 2G and 3G) after the 4.3 update? From what I've read it doesn't seem like it, but I also have trouble understanding a lot of the terms.

Someone is giving me an unlocked i337 S4 and I'd rather not pay an extra $20 for someone to do something I can do just by following a list of instructions, but if it doesn't work I also don't want to brick the phone.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Mobilicity, as far as I know, doesn't have a 2G/EDGE network. Otherwise it would have worked out of the box. This is why the network doesn't show up at all on non-AWS devices.
[AT&T Samsung Galaxy S 4 General] riversight:
Oh, I assumed it did because on my current Galaxy S 4G, I get text messages even if my phone says I'm not getting a 3G signal, my mistake. To reiterate my question, would I just be able to follow the OPs instructions on an i337 S4 with Jellybean 4.3 and get it to work on HSPA 1700 with my Mobilicity simcard or no?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yes; MK2 modem for i337 won't work, but if you're rooted, downgrade to MF3 and do the mod. That's what I did; I'm using my i337 on T-Mobile (which also uses 1700 MHz). If you try it on MK2, it'll fail to flash in QPST (though nothing bad will happen). In MF3 it works. ROM doesn't matter, though if you're running AOSP, you need to flash a Samsung ROM to do the mod. After that you can re-flash/restore your AOSP ROM.
[AT&T Samsung Galaxy S 4 General] sonny21:
This tweak enables the AWS band, so it's enabled at all times weather using Rogers or bell/Telus sim. No other settings changes required.

Correct, same hardware but software disabled bands.
[AT&T Samsung Galaxy S 4 General] sd_N:
I did. :)
[AT&T Samsung Galaxy S 4 General] ferganer:
Noob question here:

Is it possible to flash the stock T-Mobile ROM to get Wi-Fi Calling? Or is wifi calling hardware specific?

Also, is it possible to flash T-Mobile stock ROMs on a 32Gb AT&T S4?

Edit: I found that WiFi calling can be enabled if you install a T-Mobile ROM (at least this was the case for the S3). Now the question is whether I can get the 32Gb AT&T S4 and install a T-Mobile ROM.
[AT&T Samsung Galaxy S 4 General] raffacorreio:
Really???

Hey there!!

Let me see if I understood: you have an i337 from AT&T, so you enabled AWS Band on it and then you flash the stock TMO room? Have you tried check if all six LTE Bands (1, 2, 4, 5, 7 and 17) are activated too? Because the AT&T version has just two LTE Bands (4 and 17). Thanks!!
[AT&T Samsung Galaxy S 4 General] sonny21:
The band's aren't related to the rom. So if you have at&t and use this mod, you'll have access to the supported bands regardless of what rom you install, including T-Mobile one.
[AT&T Samsung Galaxy S 4 General] godzulu:
Just so I get this straight - I have done this mod already. Today, however, I flashed MDOB de-odexed so I could get Wallet working. Do I need to re apply this or is it a one and done thing? Also, am I right to assume that if I followed the op's directions, the phone re-booted etc. that I was successful?
[AT&T Samsung Galaxy S 4 General] sonny21:
You would have to test it manually, but yes it's one and done method. That is as long as you don't flash another modem.
[AT&T Samsung Galaxy S 4 General] godzulu:
Thank you
[AT&T Samsung Galaxy S 4 General] madmajd:
What happens if I get an OTA update after I install this patch? Will I lose the patch and have to reinstall it, or does it brick the phone? Or it will just update without causing any problems?
[AT&T Samsung Galaxy S 4 General] _eroz:
Finally made it back to los Angeles.
[AT&T Samsung Galaxy S 4 General] sonny21:
That's a good question. Pretty sure, it won't brick anything, just matter of having to redo mod or not. Hopefully someone answers this.
[AT&T Samsung Galaxy S 4 General] simho:
Actually I'm going to hold off on getting an S4 until questions like this get answered. If a redo is required I'd rather get the M919. Heck, if I wait long enough I might as well get the Google Edition...as long as it has the same bands.
[AT&T Samsung Galaxy S 4 General] sd_N:
yes

Yes....all lte bands are enabled after this. Just go to the hidden service menu via the post here in xda and go to the lte settings.. Choose the bottom option and there u will see ALL lte bands. Just enable them and you're ready. :) I even swapped sims with a friend and got T-Mobile lte as well as the AWS refarmed T-Mobile 4g.
[AT&T Samsung Galaxy S 4 General] mxmarcus:
That is great news. I just ordered the AT&T 32gb version.
[AT&T Samsung Galaxy S 4 General] godzulu:
When I key in *#2263# I get "RAT selection option is restricted"

Am i correct to assume that I have not enabled AWS correctly.
[AT&T Samsung Galaxy S 4 General] sonny21:
I believe you may be getting that message because of at&t csc/rom/sim card, not sure though.

Get a T-Mobile SIM card and see if you can access the menu.
[AT&T Samsung Galaxy S 4 General] russiandivxclub:
WHAT ? Are you guys saying i337 can use T-Mobile 3G/4G network ? And companies like Simple Mobile will work just fine and instead of ugly E I'll have 3G or even 4G speeds ? Cause I am kinda confused right now .... Basically question is i337 for Simple Mobile will do E (EDGE) or at list 3G ?

Thanks !
[AT&T Samsung Galaxy S 4 General] sonny21:
If simple mobile has the same AWS band as T-Mobile or at&t bands then yes.

hey if you update the Samsung galaxy s4 after you modify it to work with wind, will the modify go away?
[AT&T Samsung Galaxy S 4 General] force70:
I did the same mod on my rogers note 2 and it got an OTA and the mod stuck

sent from canada via my S4,Note 3 or G2
[AT&T Samsung Galaxy S 4 General] amilayajr:
I have a question. Will this still work if your Galaxy S4 is NOT unlock? I tried to do this but when I dial *#7284# and press call. It was says "USSD code running" then it gives me an error message "Connection Problem or Invalid MMI Code". My phone is locked with Telus. Thanks for the answers in advance.
[AT&T Samsung Galaxy S 4 General] amilayajr:
Will dialing *#0808# will do the same thing? I dialed it and have access to pretty much the same settings as you did. Please let me know? The other nunumber *#7284# does not work for me. Thanks.
[AT&T Samsung Galaxy S 4 General] Goliath27:
I'm getting stuck at step 3. Dialing *#7284# or 0808 doesn't work for me. It will start running the USSD code and then stop with an error saying "Unable to process request"

I did this before and I know I did it right, but I just wanted to see if it was still in tact and maybe do it again for the fun of it.

I'm currently on a 4.4.2 GE rom
[AT&T Samsung Galaxy S 4 General] topgun303:
I think you have to be on TW rom for dial codes to work.

---------- Post added at 10:47 AM ---------- Previous post was at 10:44 AM ----------

Your phone has to be unlocked

to the mod to work.

If 0808 works then no need for 7284
[AT&T Samsung Galaxy S 4 General] Goliath27:
Oh, well that is disappointing. Anyone know if I can at least check to see if I still have my LTE bands? I haven't seen LTE on my status bar in a while but my data hasn't slowed.
[AT&T Samsung Galaxy S 4 General] joelby2:
I can't tell if everyone has given up on getting a hold of the T-mobile QCN file or not. Is this still a project or just a pipe dream? Are we going to have to pool resources and buy a used T-mobile to get the little tiny file off of it?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
There's someone who pm'd me and has both models and both on mk2. He said he's gonna try and get back to me.
[AT&T Samsung Galaxy S 4 General] Goliath27:
Meanwhile, how can I get into the dialer settings without a touchwiz rom?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can't.
[AT&T Samsung Galaxy S 4 General] Goliath27:
Duly noted.

Now, what steps can I take to verify I'm on AWS?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Put the phone into GSM/WCDMA mode in Network Mode (or WCDMA only). Might just say 3G or 4G. Then dial the top number here. Go to basic information. If it says Band 4 on top that's AWS. If it's says Band 2 that's 1900 MHz.

View attachment 2509350

In my screenshot I had LTE on (which also uses AWS), so don't get confused. Make sure you have LTE off.
[AT&T Samsung Galaxy S 4 General] Goliath27:
Tried to dial all 3 numbers and all of them gave me a failed request. Should I try to remove the phoneutil apk I downloaded from here originally? If I can.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Are you on a Touchwiz rom?
[AT&T Samsung Galaxy S 4 General] Goliath27:
No. I stated above that I am on a GE 4.4.2 rom and someone else explained that the service codes from the OP would not work unless I were on TW. I thought the codes you gave me were for my GE. :(
[AT&T Samsung Galaxy S 4 General] Product F(RED):
No. There's no way to do it unless you're on TW.
[AT&T Samsung Galaxy S 4 General] Goliath27:
Alrighty then. Back to my square one question: Do I need to bother? or is there another way to check if my AWS settings are still on my phone after flashing to the GE?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
They'll be there as long as you don't flash or reflash a modem.
[AT&T Samsung Galaxy S 4 General] KingShao:
Could we get the same thing for the S4 mini SGH-i257M!!! I tried falshing the i337 qcm, but it didn't work so I flashed back to stock. Just updated firmware to Stock Telus and still no AWS... This is total BS for thses carriers to disable AWS. There should be laws in place for consumers to be able to CHOOSE! anyways I have the stock qcn file if someone wants to take a craxk at it or explain to me how to edit it to enable the AWS bands...

Is there a qcn file for the aws mod for this phone. Am sorry to post this under this thread, but i have been searching and searching and cannot find a solution for setting up my unlocked S4 mini with wind mobile. I bought this phone specifically for use with wind and i cannot find a solution now. I shoud have done some research instead of taking the sellers word for it.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The way we get AWS to work is we make a modem backup (the QCN file) from the same device on T-Mobile (T-Mobile here in the US uses AWS like Wind). But there's no Galaxy S4 Mini on T-Mobile so there's no AWS-enabled QCN file.
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
Any luck getting the QCN from this guy?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Nope. I kept telling him to send it to me, but he's either paranoid I'm going to steal his IMEI (really?) or he's just too proud and wants to do it himself. Haven't heard from him since that post.
[AT&T Samsung Galaxy S 4 General] AJ Newkirk:
Perhaps you should just let them know where the IMEI is in the .QCN (which is @ 17998-179A0) so that they can just zero it out in a hex editor.
[AT&T Samsung Galaxy S 4 General] traitimmapu:
I used the mod and it work on 4.2.2 mdj. If i update to 4.3 firmware will this still work or i have mod it again?

Thanks
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
The settings may not stick. And if they don't you're currently SOL.
[AT&T Samsung Galaxy S 4 General] dhomas:
If you have an AT&T i337, I can confirm that the settings don't stick after upgrading to 4.3. The modem is replaced in the upgrade and the mod is lost. The mod no longer works on the new mk2 modem, either. Do not update! Or, get a loki'd bootloader while you still can (bootloader is completely locked on mk2) and update to 4.3 without replacing the modem. I regret upgrading via OTA...
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I'm Loki'd and rooted so I can upgrade and downgrade willingly. MF3 modem works with 4.3 and AWS Mod. That's what I'm running now. You're SOL if you're on official/OTA though.
[AT&T Samsung Galaxy S 4 General] traitimmapu:
Can you show me how to get this? I have Telus I337m s4
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The i337M doesn't have a locked bootloader like the AT&T S4 i337 does, so you don't need Loki. However, you can't use i337 modems as far as I know.
[AT&T Samsung Galaxy S 4 General] traitimmapu:
so pretty much i should just stay with 4.2.2 and never update or is there any other 4.3 custom rom which support aws that i can install on the i337m?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The AWS mod is modem related. You can flash any rom but if you're using a 4.2.x modem with a 4.3 rom you might experience random modem disconnects
[AT&T Samsung Galaxy S 4 General] dhomas:
It should also be noted, however, that the mod can only be applied with a TouchWiz-based (i.e. Samsung) ROM. If you apply the mod to the modem and then flash a different ROM, the modded modem will still work provided you never flash another modem when you flash a different ROM.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Right. That's why I feel AOSP people to have a Touchwiz ROM backup on their memory card.
[AT&T Samsung Galaxy S 4 General] shibinfp:
good to know that you could install AWS modem successfully on MK6. Was your phone SIM unlocked before doing this? I have MK6 model from Bell, but is locked. I saw OP mentioned that the phone has to be unlocked but would like to know what was your phone's SIM lock condition.

thanks
[AT&T Samsung Galaxy S 4 General] Goliath27:
I'll second that. Thanks for. The advice, my phone is on aws for sure now. Had one instance of service drop but I'm gonna wait to see if that was just a fluke.

Hello. The first download link in the post does not seem to work anymore. I get this error:

Firefox can't find the file at http://mirror21.downloadandroidrom.com/download/?token=108081370

However, it's true that with i337 and OTA MK2 this doesn't work anymore anyway, is that right? I am rooted but locked bootloader.

Fred, I saw a few pages ago about someone was supposed to help get the QCN file for T-Mobile for the MK2 users. This board should support each other, can someone just do a request for this in the T-Mobile section? I feel like AT&T is screwing me left and right and I want to switch to T-Mobile.
[AT&T Samsung Galaxy S 4 General] Solace50:
is the bootloader responsible for recognizing the basebands? i guess the only way to actually morph the phone into a US/EU based phone would be to push the OTA via odin with the newer bootloaders. clearly you would not want any other MK2 other then from the M919 otherwise you would be in the same boat with others for the whole bootloader problems.
[AT&T Samsung Galaxy S 4 General] Kaze105:
Got a question regarding QPST. Got to the instruction point of going to software download. After that, clicked backup, but it says COM1 Port not available, although I clearly see my phone on COM8 enabled. The problem is that the browse button is missing for the Port and the QCN File and so I cannot change it.

Are you sure you're not just on refarmed (1900 MHz) HSPA+? LTE areas usually also have refarmed HSPA+. You can check by dialing:

Make sure your phone is in HSPA+ mode (LTE off) when you check.

To get this mod working on 4.3 we need a t mobile qcn backup running 4.3 right?...i think i might be able to get 1...i flash phones so i come in connect with alot of ppl with galaxy s4 phones
[AT&T Samsung Galaxy S 4 General] Product F(RED):
That would be great. I'd be willing to flash AT&T MK2 modem and then the T-Mobile MK2 QCN. This other guy promised he'd get it to me weeks ago (he had the file), but he was stubborn and kept saying he'd try it himself and get back to us. He never did.
