Instructions

1. Run & Install QPST Setup build 323 on your windows computer [File attached below]

2. [ With Latest Android Updates on S4, you don't need this step(2) which requires an application to be installed which is attached below named as phoneutil.apk, skip this step, How to know if you don't need, when Dial *#0808# on your dial pad if it shows a prompt poped up you don't need this step ]
Copy phoneutil.apk (attached to this post) to your phone & Install it on your phone -> go to myfiles (on your phone), browse and install it.

3. Disconnect your phone from computer & dial:
For stock android versions:
Dial *#7284# on your phone dialer and hit “Qualcomm USB settings” button
For Updated Android Versions
*#0808# for new updated android S4

4. Check “RNDIS + DM + MODEM” then connect to computer again. (Some people got it working with "DM + MODEM + ADB")

5.Your windows will install driver ( Samsung Kies if is installed, it will install drivers for your device )

6. Next, open up Device Manager on your computer and find “Samsung Mobile USB Serial Port” under Ports.
Make a note of the COM number (usually the second one)

7. Start QPST Confirguration application

8. Press Add New port, Uncheck “Show Serial and USB/QC Diagnostic ports only”, choose the COM port with the number you noted earlier then hit “OK”.

10. Choose “Start Clients” and choose “SOFTWARE DOWNLOAD”.

11. Choose the “Backup” tab, hit “Browse” for Port and choose your COM number, hit “Browse” for QCN File and make a new file name for the QCN file you will be making a backup of. We will be backing up the NV Memory on your phone just in case you mess up something. Then hit Start.

12. Hit the “Restore” tab, set Port to your COM number. Next, choose the QCN File as “337_AWS.qcn”. (I have attached below)
Then hit “Start” button. If you get a warning just hit “OK”.

13. Once that’s done restoring, your phone will reboot. Just give it about a minute as it will reboot. Once rebooted, you can insert your T-Mobile/Wind/Mobilicity SIM card and start enjoying

Tested 100% Works with all AWS network flawlessly.

FAQ

Will this void my warranty?
No.
What to do if i get this error ? "The model number in the QCN file and the phone do not match. Do you still want to restore the phone with this file?"
It is safe to continue
Will it work with other networks Rogers, Bell, Fido ?
Yes.
Phone has to be sim unlocked for this patch to work?
Yes, phone must be sim unlocked
Will it work with Custom ROMs?
Many custom ROMs work, some ROMs don't work because USB Qualcomm Setting doesnt pop up.
Is it permanent?
When you hard reset your phone(Some custom roms require hard resetting), this needs to be patched again following this guide from beginning other than that, it stays patched even if you restart it.

You are responsible on following the instructions carefully, instructions are provided assuming user has adequate knowledge to carry out basic operations. For those who know, this is done exactly the same way the NOTE 2 was done.

Special Thanks: to FastGsm.com for the phoneutil.apk
I would also like to thank the XDA Team and all those members who'd come up with this idea on the note 2 & before, indeed it wouldn't have been possible without them, originally by sjravi and other respected members

OP - Can you please add mention and thanks to the team here on XDA that originally discovered this workaround for prior Samsung models -- I believe they deserve the majority of thanks as it was their methods that make today's methods possible.

I was about to point that out. The methods of previous model that prior known to work is EXACT SAME, just the little app which allows us to access that menu for S4. I also would like to know about band 2600 and if it stays intact for Rogers/Bell.

It does -- tested and verified B7 is still "enableable" in the Band Selection program *#2263# (shows a * once selected and I maintain SOS signal on Rogers 2600).

Perfect. If you have Rogers sim, you should be able to get 2600 if you force it since most places get it unless you're in a area which doesn't. Maybe do a speed test to make sure but yeah it makes sense that it stays intact.

Folks,

Would it be necessary to change it back to MTP or MTP+ADB mode when done?

Yes, if you'd like to use the usb storage and ADB

Only if you use USB storage.

If you see my screenshot, the phone remained on B7 (2600) with 20MHZ (that is how we verify it is indeed LTE 2600). No need to worry about it "sticking". That being said, I won't be caught dead going out and getting a Rogers SIM card...ever

Would this re-lock the phone, if I unlocked it using the ServiceMenu method (i.e. not using a code)?


EDIT:
To answer my own question; patching the supplied .qcn *will not* re-lock the phone if it was unlocked using the ServiceMenu method.

No, it will not re-lock your device.

Best news ever for all S4 users.

 

[DanMc85]

would this have to be redone if at&t or alike releases a firmware OTA that updates the phone modem?

 

[FireRaider]

I am in sensory overload with all the bootloader excitement today and am trying to get this AWS TMO thing straight in my head. I have been bouncing back and forth between the the TMO threads and the AT&T threads trying to stay up to date and now am just utterly confused.
If I do this mod to my rooted and sim unlocked AT&T i337 and then put a TMO sim card in it I should be able to get the faster 3G connection speeds instead of being stuck on Edge speeds? Depending on my area and service availability of course.
Is this what I am getting with the AWS enabling? Or do we still need to flash a different modem to enable fully the TMO frequencies on the AT&T phones?

You don't need to flash any different modem, this will fully enable TMobile freq on your ATT S4
Yes you should be able to get faster 3G connection as well.

Will this enable t-mobile LTE on our phone or is that impossible?

 

[Relys]

How is this different from the service menu unlock posted last week?

 

[WorldIRC]

T-Mobile LTE is already enabled. This mod does not affect that.

SIM Unlock = Any SIM can be used
AWS Enable = T-Mobile 3G / 4G on 1700/2100 will work in addition to 1900 and LTE.

 

[ma678]

These are two different ideas.

The one you were asking is to unlock your phone which you already did, and the method listed here is to let you access AWS network.

How is this different from the service menu unlock posted last week?

SGH-I337M: LTE B7 (2600) retained AFTER the WCDMA B4 (AWS) mod

It does -- tested and verified B7 is still "enableable" in the Band Selection program *#2263# (shows a * once selected and I maintain SOS signal on Rogers 2600).

WorldIRC,

I think people would be skeptical until they see an actual CONNECTION after the mod...

LTE Band 7 (2600) with 20MHz bandwidth...

UMTS Band IV (AWS)...
