Your on lollipop OC3 build and I am not aware of anyway to connect the phone to qpst on that build. Im running my at&t i337 on T-Mobile 4.4.4 NK2 with great results. For the o.p. directions to work you must be on a build MF3 or older.

I am running this rom with fully functional wifi calling

http://xdaforums.com/galaxy-s4-tmobile/development/stock-base-4-4-4-nk2-rooted-deodexed-t2990478

You will need to be rooted and have safestrap installed to install the rom. If you do install the rom be sure to also install the correct NJ4 module files from safestrap or the rom wont work correctly. you can find that file here in post #4

NB1, NC1, NI1, or NJ4 Base Users http://xdaforums.com/showthread.php?t=2616221

Also you could try this method to enable AWS on 4.4.4

http://xdaforums.com/galaxy-s4-att/general/enable-aws-i337-roms-nj4-4-4-4-t3016651

This method seems to have mixed results.

Also i dont know if there is a need to enable aws on tombile as Tmobile shut down the 1700 band in some areas

Hey, I'm running stock 5.0.1 on an i337m (canadian). For whatever reason what I connect the phone to my computer, it never shows up on ports, just under USB devices, no matter what my connection settings are (MTP, RNDIS, RMNET, DM, etc). I've tried on several computers, with kies, without kies, rebooting both, different cables... Nothing is working. I googled around and attempted to solve this by messing with the drivers, but I can't get anywhere. My computers aren't allowing me to install drivers manually, whether I go to the folder that holds the .inf file or the file itself it just says "the device cannot start (code 10) or "the folder you specified doesn't contain a compatible software driver for your device" despite the fact that it was the standard android USB drivers. Tried to install android usb drivers, google drivers, samsung drivers, windows RNDIS drivers, nothing gets installed. I've been at this for two days!!! Has anyone encountered the same problem, or does anybody know how to get around this?
[AT&T Samsung Galaxy S 4 General] AgashU:
Same thing man, I don't know what to do. It happens to both of my S4's as they both have 5.0.1. I'm thinking of just downgrading to 4.4.2 as that's when the drivers and ports worked. One of my S4's is already unlocked using this method on 4.4.2 but upgrading to 5.0.1, it only connects with MTP + ADB, anything else, "Driver not recognized". I think qualcomm USB settings don't work well with lollipop. I suggest to downgrade to 4.4.2.
[AT&T Samsung Galaxy S 4 General] RamblinRodriguez:
I tried downgrading to 4.4.2 and 4.4.4 but i'm getting some sort of kernel issue where the phone will be stuck on the opening "samsung" image and won't actually turn on. I found, however, that I could find the port number by plugging in my phone on MTP and running Odin to find the port number. Unfortunately, it still doesn't show up in the device manager and while I could open the port in QPST, it registered no phone and therefore I couldn't install the .qcn file into it. I'll keep trying, make sure to let us know if you come up with something.
[AT&T Samsung Galaxy S 4 General] AgashU:
What carrier are you using? Did you flash stock 4.4.2 for your i337m? I have the same version as you. Did you clear cache and wipe data? It works for me. I would download the one without any carrier, don't worry, this won't affect the AWS/unlock. I have it working without carrier version. By that, I mean there are stock roms that say, Bell, Fido, Mobilicity, etc. or that have those included apps.
[AT&T Samsung Galaxy S 4 General] JDM STi:
Update: I was able to downgrade my S4 from 5.0.1(OC4) to 4.4.2 (NI2) that's stock to stock. I downloaded RWC-I337MVLUFNI2-20141016162045.zip from Sammobile (Samsung-update has it too) and used ODIN 3.09 to flash it back to 4.4.2. I found more than one people warned that not to use ODIN 3.10 as it had some sort of malware.

After my phone restored to KK, I was able to follow the steps to enable AWS on my S4!

Maybe for those whose already upgraded to 5.x, we need the thread to downgrade the phone to Kitkat to be able to process enable AWS successfully.
[AT&T Samsung Galaxy S 4 General] Inichigo:
I'm so close. I don't think you need to downgrade your device. I've been at it for a few hours testing it on windows 7/8.1 to no avail. If your on 5.0.1

Boot into recovery mode and enable CP Logging.

Recovery mode = "Power + Volume up + Home" when you see the blue recovering words let go of the power button while holding onto the other two buttons until you reach the recovery screen.

This should give you the PORTS in device manager.

After I got the ports it wouldnt detect my phone.

I then realized that the QPST link is an older version so I searched the web for a newer one. To my luck I found one. But since I'm a new member I can't share it.

Using the newer version I was able to detect my phone.

But now I'm stuck wtih "disk error while writing to file"

If anyone has overcome this part let me know. I'm trying to move to wind but this bloody thing is stopping me.

UPDATE:

The original build of QPST works! I think I figured it out!

Try going into your *#9090#

and if its set to: [1]DM/DUN over HS-USB

Change it to this [2]DM/DUN over HSIC

The one with the * in the box is the one its currently set to eg. [*]

It should restart your phone and you should be able to detect your phone with the 2.7 323 version and backup your NV + Restore.

Update: I was successful in applying the AWS patch to my phone. It WORKS!

Cheers!

cant access my device on pc

I could not proceed for step 4 as my pc does't read my device if I change my usb mode can you please help me in that.... thanks in advance
[AT&T Samsung Galaxy S 4 General] joe_modo:
[MENTION=6915137]Inichigo[/MENTION]

I cannot for the life of me get this method to work. Though half the time, I'm working with a shoddy USB...

Okay, so I change it to DM/DUN over HSIC

The computer is still recognizing the phone as an MTP/ADB device, and QPST does not recognize a phone on this port. Do I still need to change the original Qualcomm setting? In doing so, I go right back to "device unrecognized".

Also, booting to recovery offers me no CP Logging option.

EDIT:

Does this, in fact, modify the Modem.bin? If so, would it be at all possible for you to dump yours, so I could simply build a flashable AWS updated OC3 modem, and bypass this? Or does it change something else regarding the qualcomm chip? I only assume there may be a change to the modem.bin considering a hard reset or flash containing a modem will update the phone, losing the update.
[AT&T Samsung Galaxy S 4 General] Inichigo:
Yes you want to set your Qualcomm settings.

"Dial *#7284# on your phone dialer and hit “Qualcomm USB settings” button

For Updated Android Versions

*#0808# for new updated android S4"

I got this working on 5.0.1 and if I recall I used the RNDIS + DM + Modem setting.

I don't think it modifys the modem.bin.

EDIT: I think you have to be in the right qualcomm setting for CP LOGGING to show up! "RNDIS + DM + Modem"

NOTE: NOW USING THIS WITH AN AWS SERVICE PROVIDER. I HAVE NOTICE BAD SERVICE CONNECTION COMPARED TO PHONES MADE FOR AWS USE
[AT&T Samsung Galaxy S 4 General] joe_modo:
Thanks bud. I'm pretty well versed with android in general, but this is my first time venturing into the world of basebands, modems and such. (not exactly true, I've done some mild work with an iphone once upon a time, and I flashed another carriers modem to an old nokia brick almost a millennia ago!) It's exciting to be breaking new ground and learning new things!!

I'll test this evening and edit this post with my findings/results. I'm currently on a custom 5.1.1. rom from the i9505 (able95 s6 full port, be aware, it's got serious network issues on our phone, AWS will be the least of your worries), and going to stock recovery boinks my "custom" CSC, so I'll need a backup and maybe a little extra tinkering to get this to work just right for me. Your advice that the Qualcomm needs to be set first is likely the advice I needed to proceed.
[AT&T Samsung Galaxy S 4 General] Obscenic:
I grabbed a used S4 (SGH-i337m) for a friend, unlocked it, downgraded (Odin) from 5.0.1 to 4.4.2 so I could AWS unlock (phone is NOT rooted). Did the AWS unlock successfully. Registered with Wind SIM on Wind in Canada (used to be a Bell phone). Everything is hunky dory; but I'm wondering if it's possible to re-upgrade to Lollipop 5.0.1? Will the OTA update work; even though it's on a different network? Will flashing a 5.0.1 ROM with Odin remove AWS frequencies? I've scoured the internet and no one seems to have a solid answer for this. I'm hoping one of you brilliant regulars can answer it once and for all :)

Thanks in advance!
[AT&T Samsung Galaxy S 4 General] _zevulun_:
I am ready to throw this phone at the wall. Got it all working fine at home and on the road, no such luck at work though.

I noticed that instead of having full bars at home like normal, I only had 3. No biggie. At work though, it's jumping back and forth from 2 bars to "no service".

Is there a way to fix this or is the antenna just that crappy? The antenna in my tmobile branded S3 works just fine in the building...
[AT&T Samsung Galaxy S 4 General] willzzz88:
BTW is there a hack to open UMTS/HSPA+ on 900MHz on the AT&T S4 like the Verizon version does?
[AT&T Samsung Galaxy S 4 General] Goliath27:
Ok so I did this on the stock rom and recently changed roms to Goldeneye

I went to do it over again and can't get the meny for *#7284# to work. Gives me an error if I hit dial, before I didn't have to do anything and it would open on its own.

Now, how do I check to see if the bands are still open, I'm not sure if the rom has changed the modem which I am sure it didn't.
[AT&T Samsung Galaxy S 4 General] AlEjAnDrO812:
That rom not change the modem.. And you cant access the menu because that rom is based in I9505 firmware
[AT&T Samsung Galaxy S 4 General] Goliath27:
It did not change the modem? So I'm still on the correct bands?

I tried checking the bands but I only seen lte 4.
[AT&T Samsung Galaxy S 4 General] sonny21:
You need to install the app again to access that menu.
[AT&T Samsung Galaxy S 4 General] m00nman:
Flashed using this method (instead of the cwm flashable) and it looks like after flashing full rogers stock rom with odin (it did flash modem) i did not lose aws. It seems this method flashes something else which is not touched by the rom/modem flashing.
[AT&T Samsung Galaxy S 4 General] rfb813:
Try *#0808# When I used Fast GSM to unlock my phone after I installed the phoneutil.apk it said use that number. I worked.
[AT&T Samsung Galaxy S 4 General] Goliath27:
It wont install, every time i try it fails.

How do I check if my aws is still connected after a new rom?
[AT&T Samsung Galaxy S 4 General] AlEjAnDrO812:
This code works :)
[AT&T Samsung Galaxy S 4 General] illmaticone:

[AT&T Samsung Galaxy S 4 General] m00nman:
My phone was originally rogers branded, i unlocked it and used this hack to make it work with wind (which is aws only) If you are not using aws carrier, it wont matter and you can't really check.

It took a few times, but I finally got my AT&T S4 (i337) to pick up T-Mobile's data.
[AT&T Samsung Galaxy S 4 General] Duffmantp:
Can you.post the apn settings
[AT&T Samsung Galaxy S 4 General] Goliath27:
T-Mobile. And I used the *#0808# up above to get into the phone menu. Now I'm all good!!
[AT&T Samsung Galaxy S 4 General] simho:
Just a question I thought of. If you turn phone off, insert T-Mobile sim and turn on, shouldn't the phone automatically pick up the correct apn settings?
[AT&T Samsung Galaxy S 4 General] cariga39:
that's for apn setting this trend is base on AWS bands on the galaxy s4
[AT&T Samsung Galaxy S 4 General] turilo:
Will a factory restore or Odin flash of official stock firmware terminate this mod?
[AT&T Samsung Galaxy S 4 General] simho:
Someone on a previous page noted that they Odin'd back to stock and didn't lose this mod.

I've changed roms and didn't lose the mod. I'm not sure what would cause losing it other than flashing a new modem.
[AT&T Samsung Galaxy S 4 General] Inichigo:
A wind Rep. Told me that if you upgrade your phone it will remove the AWS fequency. So you would have to do the process all over again. But I've been using it on 5.0.1 with AWS so I know for a fact it works on lollipop.

I've recieved some small OTA updates(from my Bell phone) after implementing the AWS fix. I'm not sure if its 100% Wind or not
[AT&T Samsung Galaxy S 4 General] Obscenic:
So how did you get updated to 5.0.1 with AWS unlocked? Did you flash it?

Upgrading AWS-S4 to Lollipop

Hey,

Have you got anywhere on this? I've got my S4 with Wind on 4.4.2, and suspect I have been the target of an attack after some very strange activity! So I want to get upgraded to prevent StageFright.

Phone stats:

Make: Samsung Galaxy s4 Model #: SGH-I337M Android Version: 5.0.1 Baseband Version: I337MVLUGOH1 Kernel Verion: 3.4.0-4508315 DPI@SWHD7402 #1

Old Carrier: Telus (unlocked by carrier) New carrier: Wind mobile

Problem:

After researching web/youtube, I had bought the S4 on the premise that I could add the AWS band on to the phone with relative ease after watching a youtube video tutorial. (I'm not extremely technical but I'm a DIY guy and thought I could take on the challenge)

After purchasing the phone, I started following the steps in the video and quickly realized that the OS on the tutorial was older than my newly purchased phone with a updated OS. I've entered '*#0808#' (this does work to get into the settings). The problem is, that after I change the settings from "MTP" to “RNDIS + DM + MODEM”, my phone will not connect to my computer and thus renders me unable to continue with the tutorial. (computer says "unable to identify USB connection")

I'm worried because I need to have my phone up and running before the end of this month because I have to return a ****ty ACER phone I purchased temporarily from costco and it's running out of its 90 day return policy.

I know the phone is already 2 generations behind its predecessors but I'm hoping someone in this forum can help me out!

Identify past build for your phone by checking Google and sammobile. After you get that figured out download the build from Sam and apply via odin. If you have a Knox bootloader you can only go back to a Knox fw.

AT&T S4 Natively Running On T-Mobile LTE

Hey I'm just wondering do I really need to enable AWS bands on this phone? Because heres my story on this phone. I just got this phone trading in my go pro and it was locked to AT&T but I managed to sim unlock it and now I'm running T-Mobile on it. Here's the kicker the LTE signal is native as I didn't do anything it was already showing "4G LTE" the moment I booted it up. I'm running stock AT&T firmware NB1. I've noticed the speeds are incredibly FAST!!!!! 41 Mbps Down and 34 Mbps Up!!!! What will enabling AWS achieve if I enable it? I'm using the phone as is unlocked with T-Mobile sim inserted no tweaks were done to the phone but I did root it with Towelroot but thats all I did. Somebody please explain how does the Galaxy S4 AT&T just work natively on T-Mobile LTE Network??? But do get this I'm only getting 3 bars of LTE and yet these speeds are flying colors........

[AT&T Samsung Galaxy S 4 General] PGowdy:
I had the exact same inputs .. A Rogers I337M that I wanted to work on Wind. I had to downgrade to Android 4.4.2, and It seems I had to do this procedure on my Windows 7 machine .. my Windows 10 machine didn't seem to want to cooperate. I did get it done, with some help. I have since upgraded to Lollipop 5.0.1 and the modem patch endures. For your uncertainty whether the phone is unlocked or not, you could take it in to a Wind store and ask them to check it out.
[AT&T Samsung Galaxy S 4 General] audit13:
If the i337m is not sim unlocked, the phone can be unlocked using the free method by downgrading to 4.4.2, installing the 4.2.2 modem, rooting, and running region unlock apk.

[AT&T Samsung Galaxy S 4 General] salmanaslam:
Canada

Rogers Samsung Galaxy S4 (SGH-I337M), Android version 5.0.1 to use with WIND Mobile (No firmware downgrading required).

Steps to make it work on AWS bands:

Purchased SIM unlock code for CDN$ 15.00 by providing IMEI.

Phone unlocked by entering SIM unlock code.

How to make Windows recognize the USB - RNDIS + DM + MODEM port and install proper drivers:

Dial *#0808#

Choose RNDIS + DM + MODEM and click Reboot button. Windows will not recognize the USB port.

Dial *#9090#

Choose [2]DM/DUM over HSIC[] (Selection will have (*) at end of line). Still Windows will not recognize the USB port.

Now shut down phone and boot phone in Recovery Mode (Volume Up + Home + Power button). Once menu options appear select "Enable cp logging" (second last option).

Hook the USB cable. Windows will recognize the phone and USB port.

Make sure no SIM card is in phone. As I find that if SIM card is present phone USB port keep connecting and disconnecting to Windows.

Follow the process in the beginning of this tread to install AWS patch.

At 100% progress phone will reboot.

Turn off the phone. Put WIND Mobile AWS band SIM. Turn on phone and it will connect to WIND Mobile network.

Need help, S4 SGH-i337 to AWS

I purchased a brand-new out of the box, Unlocked AT&T Samsung Galaxy S4 SGH-i337 from eBay after reading and knowing that it can work with the AWS frequency, I could have grabbed a T-Mobile but was not aware of the differences, which I'm now discovering as I dig up out-dated threads and methods to get this ridiculous thing to function with Wind Mobile in Canada on the AWS frequency. Android version 4.2.2

I have the US Model, but I live in Canada

I encountered an Issue where I believe I have accidentally reversed its "unlocked" state, using the method where you go through the menu, hit back 3 times, type in the select key, 1, Q and 0000 selecting a couple options that then reboots the phone. Now every time I start up the phone it prompts me for a damn SIM PIN which when asked about to WIND they said there's no such thing as purchasing a SIM PIN to unlock it...

To get the AWS working specifically, I heard that all you had to do was select a network and I can't recall where I encountered this phone command and tested it, but nothing has worked either way so far.

I'm at the point now that I don't even know if I want to keep tampering with the phone and just sell it for a different model, but now I'm facing the issue that I might have locked it back, with the SIM popping up.. I found one PIN generator and Lo and behold, it requires me to do either ridiculous surveys and hand out my personal info, sign ups or purchase 50 dollar gift cards.

Help is appreciated.. I've gone through all the convoluted information, and I'm at a complete loss and totally pissed off and frustrated
