I have an i337 (AT&T) model in MF3 modem. If I'm reading correctly you were able to make it work on a newer modem? I am loki'd so I can flash any modem. I just want the mod to work on one of the latest modems.
[AT&T Samsung Galaxy S 4 General] sja44:
Yes. S4 on 4.3 baseband i337MVLUEMK6

Also the *#9090# workaround still seems to work on FNC1. At least the menus are the same. As I have already enabled AWS, I can not confirm fully workable, but at least it looks so.

so *#9090# select 2, will reboot

then *#8080# and follow steps as outlined here.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I'll give it a whirl using MK2. I'm just confused as to how you were able to the QCN file from the OP to flash because it fails at 5% on any modems past MF3. Will give it a shot though.

---------- Post added at 09:09 PM ---------- Previous post was at 08:37 PM ----------

Didn't work with MK2. Failed flashing at 5% like the rest. Nothing after MF3 seems to work with the QCN file.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
just use safe strap ..flash the mf3 modem then uninstall safe strap and call it a day

I'm on MDL bootloader with Loki, so I don't even need Safestrap. I can flash anything back and forth. I just wanted to be able to use a newer modem with the mod.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:

Great to confirm fnc1 modem is still AWS hackable by this mehod.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Wait, so just to clarify, you guys (i337M, not i337) were able to flash the latest KitKat modem and also apply the AWS QCN file from the first post? Because I'm trying to flash MK2 onto my i337, which works, but then the QCN fails at 5%.
[AT&T Samsung Galaxy S 4 General] sja44:
YES, I337M, 4.4.2 Baseband I337MVLUFNC1
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I flashed NB1 (sister modem lol) and it didn't work. I'll try ODIN-ing the modem because I've been installing it through recovery thus far. Keeps failing flashing at 5%.

EDIT: Still didn't work.

Any news?
[AT&T Samsung Galaxy S 4 General] ncotton:
For those unable to use the dial codes to do part 3 (if the USSD code *#7284# does nothing) there is a work-around.

If you have a launcher that can make an "activity" shortcut you can make a direct shortcut on your homescreen to PhoneUtil -> SetPortUartUsbMSM8960.

This will bring up the Qualcomm USB settings options.
[AT&T Samsung Galaxy S 4 General] att85:
I have some singal issues and not sure why..

If I enter *#9090# on dialer and select something...does this somehow change any radio / modem / signal settings? I mean really only by just hit one of these options in the menu.

If yes, how do I get back to default?

bricking my phone or any other issues :confused:

I'm new so anything about flashing and stuff, I have no idea

Also, if I upgrade to the newest software would my apps and stuff be backed up onto the new software?

Will this be permanent? Do I need to repeat it for each update?
[AT&T Samsung Galaxy S 4 General] amilayajr:
I would assume, this will not work with Telus/Koodo? I tried it for some reason my computer sees my S4 in device manager but the problem is in QPST software, it's always saying "No Phone Connected" when I try to make a qcn backup. I chose every single comm ports but no luck always says "no phone connected". Any ideas?
[AT&T Samsung Galaxy S 4 General] floydhead:
I just recently applied this Mod on my Canadian i337m and can confirm that it works 100%. I'm on fnc1 kit kat.

However when I restored the aws qcn file, I got a blacklisted imei. I then restored my backup and got my imei back while losing aws. Next I restored the note 2 aws qcn through qpst and which works perfectly fine, but this gave me "0" imei.

So far I'm getting great signal quality with 4G and all but a bad imei. How can I fix that without losing aws?

I tried various methods but to no avail. Any help would be appreciated. Thanks

I've having a problem installing the phoneutil to my phone. I tried regularly installing it, moving it to system apps, and installing from adb. In adb I get a missing shared library failure, and I'm not sure why. Any help? Thanks.
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
Don't ask me how, but you should be able to use a hex editor and add your IMEI to the Note 2 QCN that you're flashing.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
That's impossible. The QCN file has no IMEI number in it. It was deliberatly removed to prevent this.
[AT&T Samsung Galaxy S 4 General] floydhead:
I am relatively new to all this, tried looking, searched over the internet about locating IMEI in a hex file but can't find it. I have downloaded the hex editor and have made backup copies of the qcn files in case anything goes wrong during editing. But can't find the location of the imei. Your assistance would be much appreciated. Thanks
[AT&T Samsung Galaxy S 4 General] floydhead:
Finally got it done

After much research on how to inject/restore original imei back to the phone, I was able to enable aws frequencies using the Note 2 QCN (that has "0" imei) and following this guide I was then able to restore my original IMEI. All is working great!

So, for those who would like to edit their imei's please head first to the note 2 section and download the QCN ("0" imei) from there...and then follow the steps in this thread to QPST the Note 2 QCN into your phone. If you are on kitkat and have a Canadian Galaxy S4 then the code *#7284# wont work for you. Instead use *#0808# and you will see the options. Follow the steps from there.

Once that is done, follow the link below to restore your imei back to the original. The guide is very simple and the user even has a step by step video on youtube.

Successful UPGRADE to 4.4.2 with AWS

Have just successfully upgraded 2 AWS enabled Galaxies S4 I337M to Android 4.4.2 (Modem NC1) from 4.2.2 (Modem MG1) through simply clicking "Upgrade Firmware" button in Samsung KIES software on Mac! Both SGS4 were rooted and unlocked from Rogers. AWS was enabled on original 4.2.2 and now works perfectly on both devices(WIND Mobile connected). All programs work well and no information is lost.

[AT&T Samsung Galaxy S 4 General] Product F(RED):

[AT&T Samsung Galaxy S 4 General] jahrule:
Nope not possible to enable aws or nope there is not a tutorial?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Not possible to enable AWS. Frequencies are not just enabled in software, but also by hardware (to put it very generally). The i337 and i337M are just the M919 (AWS-enabled North American variant) with AWS disabled (which is why we can enable it), and with a locked bootloader. I'm confident the i9505 doesn't have the same hardware as the i337/M or M919. It has different antennas and filters internally. It also has a different NVRAM structure from what I've read (Flashing a US variant's QCN file will corrupt your modem).

Used this tutorial: android.gs/root-canada-galaxy-s4-i337m-on-vlufnc1-android-4-4-2-kitkat/

Don't forget to install SuperSU from Play Store after the process if you have none. Otherwise RootChecker wouldn't show the device is rooted.
[AT&T Samsung Galaxy S 4 General] jian1:
ok, after frustrations this is how I got it worked on my rogers galaxy s4 with android 4.4.2.

First of all, the code dialing is different than the original post, it is actually *#0808#, and in order to let your computer recognize your phone, one has to install Samsung Kies, and make sure you select "installing the samsung unified driver" option, after a rebooting, finally my phone got recognized.

Rogers i337m to enable wind aws not working?!!

Can anyone help me. I have samung S4 i337M (canadian version) originally locked to Rogers, was sim unlocked. Trying to get it to work with WIND!

I had been updated over wifi to Kitkat 4.4.2, its NC1...

Using Odin v3.0.9 to flash

I originally flashed the "CF-Auto-Root-jfltecan-jfltevl-sghi337m", but when I used root checker, it did not work.

Used motochopper first time didn't work, then did *#0808# to change settings to "DM - Modem - ADB", then it worked. used root checker, said it was rooted. Flashed "337_AWS.qcn" file. I think it worked because I can see the the 1700 band, and it recoginises the wind (home & away) network. The data works, but can't get service?!

I run the TWRK - not sure what that did.

Now were here! Any help is appreaciated! please repond with idiot proof answers - as i'm bit of a noob. I've done a lot of searches to and dead ends. One comment suggested flashing "MDL modem" don't know what that means, or where to find such a file. Is that the same thing as the MD5 file from the CF-auto-root?!

Edit: Flashed Modem Mk6 nothing happened (infamousdevelopment.com/forum/topic/2288-modems/)

It seems i get a "Sim car or network error"?

Again any help is appreaciated! thank you in advance!
[AT&T Samsung Galaxy S 4 General] TikiThePug:
I was already on KitKat when I flashed this mod. Worked fine with a Wind SIM. Then I sold the phone and got another brand new S4. I'm weird I know, lol.

Well to avoid issues again, you may want to start over. At least I would if I were in your situation. Here's a run through of what I did when I got my Rogers unlocked phone:

1. Update to official KitKat using all files and flash via Odin.

2. Perform AWS mod. (remember to revert to MTP+ADB afterwards using *#0808#)

3. Root with CF-Auto Root.

4. Have a beer.

Hope that helps.
[AT&T Samsung Galaxy S 4 General] crazyaces2:
Not that it probably matters, but shouldn't I root before doing the AWS mod?

Also do I need to flash another modem or anything?!

Thanks for your help.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You don't need to root if you're on MF3 modem or earlier (since those are the only modems the mod works on on the AT&T model. If you have the i337M, it'll work on even the newest modems I believe). The mod works at the modem level and is undetectable.
[AT&T Samsung Galaxy S 4 General] crazyaces2:
How can I tell what my modem is? I have i337M from rogers.

thanks!
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Go to Settings -> About Device -> last 3 digits of the baseband.

But you can just follow the instructions to flash the mod. Worst case it fails and nothing changes.
[AT&T Samsung Galaxy S 4 General] crazyaces2:
Didn't work:(

It can connect to data like before, but says "no service". That being said it did say it was connected to wind for 3 seconds, this happend before,but then immediately goes back to no service. I'm thinking of calling wind, could be an issue with them blocking my eiei number or something? who knows?!
[AT&T Samsung Galaxy S 4 General] TikiThePug:
Before you do that, make sure you have the correct Wind APNs set up in Settings > More Networks > Mobile Networks > Access Point Names. If that's set up fine, try forcing the OS to connect to only the Wind network by doing a mobile network operators search and choosing Wind manually. That menu is under Network operators, under APNs.
[AT&T Samsung Galaxy S 4 General] crazyaces2:
It's NC1

So is that good or bad?!
[AT&T Samsung Galaxy S 4 General] Product F(RED):
According to this guy, it works:

http://xdaforums.com/showthread.php?p=51904393

So congrats. No root necessary :) Just know you might have to reapply it every time you get an update because each update usually comes with a new modem.
[AT&T Samsung Galaxy S 4 General] crazyaces2:
when I did the AWS mod I typed *#0808# and change the usb settings, and used "DM - Modem - ADB", but origianlly it was a different one other people were suggesting. which option did you pick?

thanks
[AT&T Samsung Galaxy S 4 General] TikiThePug:
Edit:

I used the RNDIS + MODEM, I believe. Or something like that. I just followed the instructions word for word. I actually did this process for three S4s, and they all seemed to have worked. So you can choose that option when doing the mod, then change it back to MTP+ADB after the mod to get USB Storage working again.

[AT&T Samsung Galaxy S 4 General] TikiThePug:
You mean you still can't pick up a Wind signal? Have you tried the manual steps I outlined a few posts above?

Are you sure you followed the steps to the letter? i.e. You made an NV backup and then restored with the given AWS file? It's possible that you have a bad file, or that your phone got disconnected from the program's port that you selected while it was restoring. I would suggest (if necessary) flash stock firmware and starting over again. You never know where you went wrong.
[AT&T Samsung Galaxy S 4 General] golgiapp:
Yep, followed them to the letter and made my backup. If I reset the phone I get signal again which is good. I am running the stock firmware and I have only rooted it thus far and have had it unlocked.

What concerns me is I'm not seeing the qualcomm option after dialing the code. Just the AP and CP options.
[AT&T Samsung Galaxy S 4 General] TikiThePug:
Yeah, if you're running KitKat, that button no longer appears. It shows up like this instead when you use *#0808#.

[AT&T Samsung Galaxy S 4 General] dhomas:
If you're on 4.3 on an AT&T S4, you'll need to install the modem from 4.2.2. I had the same symptom when trying this on my AT&T S4 (getting stuck at 5%). It's all in the modem.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The modem is MF3. I'm running MF3 modem with AWS mod and a T-Mobile ROM. So my phone is basically a T-Mobile S4 lol.
[AT&T Samsung Galaxy S 4 General] golgiapp:
I upgraded to 4.4 thinking that may have played a part but I'm still getting the same error message after 6%.

Can I do this? Install the 4.2.2 modem temporarily to implement the AWS fix and then revert back to the modem I'm on which is I337UCUFNB1.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
No. The mod doesn't stick between modem flashes.
[AT&T Samsung Galaxy S 4 General] golgiapp:
I found the radio page because it sounds like I need a different modem to get AWS. Two questions if you'd be so kind...

First, I am running 4.4.2 and currently have modem I337UCUFNB1. (My phone is unlocked also.)

Which of these modems would be compatible with my phone? Do I need the unlocked one listed below?

modem_CWM_I337UCUAMK2.zip{11/30/2013}(ATT)

modem_CWM_I337UCUAMDB.zip(4/27/2013)(US)

modem_CWM_I337UCUAMDL.zip(5/8/2013 W/O AWS)(US)

Modem_CWM_I337UCUAMDL_Unlocked.zip(5/8/2013 AWS ENABLED)(US)

modem_CWM_I337UCUAMF3.zip(7/9/2013)(US)

UPDATE - So I installed the MF3 radio and was able to flash AWS successfully. From what I gather that's the only radio it'll work on. Getting average speeds of 30 down and 5 up. Not bad at all.

I hope this information benefits other noobs toiling away.

WCDMA only

LTE/GSM auto

Oh nevermind, choosing LTE/GSM auto does pick up AWS bands
[AT&T Samsung Galaxy S 4 General] Product F(RED):
GSM/LTE means EDGE/LTE. Meaning on 4G fallback. AWS LTE is already enabled on all AT&T phones out of the box. The AWS mod enables AWS 4G. You would want "Automatic".

[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
If MK2 is working OK for you, then you must be in an area where either T-Mobile has HSPA on 1900MHz, or really good LTE coverage. If you travel to an area with AWS HSPA only, then you'll drop to EDGE.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
H+ = 4G

You must be using an international ROM. H+ is short for HSPA+ which is what our US carriers call 4G (it's really more like 3 or 3.5G). In your case, when you see "4G" come up, you're on LTE. This mod is for HSPA+ though. LTE always has and will work on AWS.

No, you won't have any issues or errors but it you use Odin to go back to stock you'll have to redo the mod.
