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?

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.

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?

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

---------- Post added at 07:08 PM ---------- Previous post was at 07:07 PM ----------

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

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

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...

    Oh ok. Can I install that .qcn modem file using Odin?
    I think only with QPST

    If you can't get QPST to detect phone (0) then try this:

    dial *#0808#, change to RNDIS, if that doesn't work try RMNET, if it still doesn't work dial *#9090# and hit 2 for HSIC. Fire up QPST, restore 337_aws.qcn file (backup yours first), after phone reboots go to mobile network and pick access point names, make sure dot beside your provider, go to network operators and choose "automatically select preferred network". Boom, done.
