What I did I took the phone to someone else who had Windows XP installed on his laptop and QPST recognized the COM ports instantly. I'm not sure but I guess there is something to do with Windows 7 or computer hardware but anyways it worked and I was able to enable AWS through QPST.

Anyways thanks for the information it might help someone with the same problem or maybe next time if I'm stuck I could give it a try.:)
[AT&T Samsung Galaxy S 4 General] Kushblow:
Glad you got it working, mine was a weird modem baseband... Last 3 digits NI2, no idea what version that is but the phone was running 4.4.2 locked to Rogers and using this method unlocked to work flawlessly with WIND 1700 HSDPA. Truly a life saver.

Still had to unlock the phone first though and use the method above to get QPST to recognize the phone. So far all wifi blue tooth etc works great!

Happy new years folks!
[AT&T Samsung Galaxy S 4 General] destructionj:
My understanding is that the AWS file will not work on baseband/modem firmware newer then MF3 thus in order for me to get it to work i had to find a combination of ROM, and module file that would work with the MF3 baseband. I thought i read that once the modem is updated you can flash new modems in with safestrap and the AWS settings will stick, however im unsure about this method. Im still trying to piece everything together. Up-to-date methods that would be common sense to veteran developers are still new to me because i have only been on android for a week. I would gladly take any insight from someone more knoldegable on my goal to get on a 4.4.4 tmobile based custom rom with open AWS settings. I have so far been unable to get the MF3 modem working correctly on 4.4.4 roms Any help would be great. I am also still a bit unclear on what kernels to use on which roms. Most likely somthing is being overlooked on my part.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
There's an alternative, more hands-on method that may work for newer firmwares. Try this: http://xdaforums.com/crossdevice-dev/sony/thread-progress-please-leave-im-updating-t2871269

Essentially, the QCN file contains all of the settings that tell the phone's modem how to operate. Using the method that I linked to above, you'll be making the edit(s) directly on the phone rather than flashing the QCN to do the work for you.

We're lucky though because we actually have a menu in TouchWiz ROMs to enable RNDIS + DM + MODEM (*#0808# or *#7284#). The majority of the guide is all about enabling that mode on non-Samsung devices, which don't have a menu like we do for it. So basically, following that guide, you can essentially ignore steps 1-16 (aside from downloading the required files to that he linked to) and continue from step 17 after enabling RNDIS + DM + MODEM.
[AT&T Samsung Galaxy S 4 General] ozoneaction:
Thanks for the reply! I was getting ready to give up on getting this to work. I had tried to flash the MF3 modem using ODIN and didn't have any luck doing that. Didn't think to try to flash the MF3 modem using safestrap. I have installed safestrap. and downloaded the modem. Is it easy to flash? Guess I need to read a little more about using safestrap to flash a modem before I do it.

THANKS PSC09160820!!

I installed I337_UCUAMF3_Modem_RockRatt.zip using safestrap. baseband version then showed as i337ucuamf3. QPST then ran the restore to completion instead of getting QPST Received an invalid command from the phone. Phone rebooted and a 4G LTE greeted me! yay! No more EDGE!
[AT&T Samsung Galaxy S 4 General] destructionj:
WOW Thanks for the help it appears to have worked, it took some trial and error but I think I got it now. Long story short I used RF NV Manager and copied the value from the data table 1877 on the old aws file people were using.

The modified file people are using on the MF3 and older firmware has a value of

(115868544).

My stock i337 value on line 1877 had a value of

(82314112)

Simply pull the values with RV NV Manager then replace the value on line 1877 to 115868544

Write NV

File-Write NV items to phone.

Used terminal emulator to enter command

su

setprop persist.usb.eng 0

reboot.

Used NV manager to re-pull data to confirm that it took.

AWS on 4.4.4 NJ4

Im in a refarmed area and get lte most of the time anyway. The question is how can I tell it Actually worked :laugh::laugh:
[AT&T Samsung Galaxy S 4 General] Product F(RED):
AT&T ROMs have no "Network Mode" menu to turn off LTE, so you have to do it like this:

- dial *#2263#

- choose WCDMA band preference

- choose band 4

Do you get service? If you do, it worked. Now, to actually see what band you're currently using, you can just dial *#0011#

To undo (because you'll only have data; no calls and texts at this point), continuing from the above steps, hit Menu - "Back" - LTE Band preference - LTE Band All - Menu - "Back" - Automatic
[AT&T Samsung Galaxy S 4 General] destructionj:
Option on *#2263# under WCDMA Band Preference with WCDMA 1700 selected shows 4g on top, data is working. *#0011#

shows RRC:CPCH,Band4.

I think im good to go.

Also I am no longer on the stock att rom. after testing the waters I moved over to the T-Mobile_NK2_4.4.4_ROM_for_I337 and still was able to perform all the same functionality when flashing.

One question, I made a backup of the qcn file using QPST Software Download >Backup tab after I did the update to the phone. Can this qcn file now be applied to other i337 phones on newer roms that wont work with the old file?

In other words, is this file I created just a updated version of the original OP file? if so would it be beneficial to others ?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
So you got it to work! Awesome. I'm glad it worked. Now people can do this on the latest baseband. I guess I'll make a new thread.

To answer your question, yes, but you have to remove your IMEI from it. Additionally, just like the old one became outdated/no longer worked, there's no telling if it will happen again.

Alternatively you can make one every time a new modem comes out if it stops working. I have a Note 3 now, so as much as I'd like to do it, I can't.
[AT&T Samsung Galaxy S 4 General] Buccanero:
Hey, good to know! I recently got a Koodo S4 also with that NI2 baseband, and there is really not a lot of info on whether this method works for that modem.

Did you unlock it by the hacky method, or by paying for an unlock code?

Do you have to be rooted to do this?

Thanks!
[AT&T Samsung Galaxy S 4 General] destructionj:
unsure about the modem on the Koodo S4. Someone can chime in if im wrong but for the I337 with NI2 baseband you have to flash back the baseband to MF3 with safestrap and then flash the I337_UCUAMF3_Modem_RockRatt.zip file. Then you can load the 337_AWS.qcn file into QPST and be good to go on OP directions. This means root access is needed to get safestrap running.

Thanks for all the help. I see my file is a bit bigger then the original AWS one and honestly I am a bit vague on both the legality and procedure involved with altering the file to make it safe and shareable to others.

However, that being said, It would be in good faith that I would be willing to help the development of new procedures if needed and able to.

Thanks again for the help
[AT&T Samsung Galaxy S 4 General] Buccanero:
Thanks, but Koodo is a Canadian telecom, so this is the I337M S4, not the I337 one. MF3 is for the AT&T I337 version.
[AT&T Samsung Galaxy S 4 General] wellaflex:
Guys,please help me if you know

I have a N9005 phone and after enter the *#0808# and select RNDIS+DM+MODEM(even try it with DM+MODEM+ADB) it's says saved.

Then my pc says "USB NOT RECOGNIZED" and in Device Manager nothing apear to Ports.

Windows 8.1, Kies and the samsung drivers installed.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Do not attempt this mod. First of all, unless you're in North America and you're on a carrier that uses 1700 MHz, this will do nothing for you. Secondly, this is NOT for your device. Thirdly, the antenna for 1700 MHz/AWS is not in the N9005, so it can't even be enabled.
[AT&T Samsung Galaxy S 4 General] PSC09160820:
Glad it worked for you. When i'm in a bad LTE coverage area I sometimes do *#2263* and change between LTE/WDCMA and AUTO so I get the best of what's available in my area. Then I get 4G+ Instead of edge when there's not LTE available. i also enabled tethering/hotspot on this phone so i'm all set! 80 bucks per month of unlimited everything, can't beat that!
[AT&T Samsung Galaxy S 4 General] wellaflex:
I don't want to enable AWS and i know this is for s4 ....i want to chance the Imei with QPST and the port not apear in Device Manager :(
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Nobody can help you with that because it's illegal and against the rules.
[AT&T Samsung Galaxy S 4 General] Kushblow:
Sorry for the late reply.

I didn't have to flash to MF3 modem with mine, this QCN method worked for me great with Nl2 baseband. The only workaround I had to do was somewhere back in this thread where someone posted something that made QSPT recognize my phone port as it wasn't doing so before.

Also I had to pay for an unlock code, I think I tried the hacking method and failed. Ended up shelling out 25CAD for the sim unlock.

Also yes you have to be rooted, CF Auto Root worked very nicely and is extremely easy to do.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
For whatever reason, it's always been the case that the i337M (Canadian S4 from Rogers/non-AWS model) could always do the mod. MF3 modem is only for the i337 by the way (AT&T US model), not the i337M, so don't try to flash it.
[AT&T Samsung Galaxy S 4 General] mr_interested:
Hello.

Hopefully someone here can answer a few of my questions.

Details:

Canadian Galaxy S4 Koodo i337M phone

unlocked using a unlock key purchased online.

stock Android Version 4.4.2

Not rooted.

My Issue:

I have two sim cards one is the Koodo card that came with the phone.

The other is a TMN sim card for a European phone number that is used when traveling overseas.

Yesterday when I put the European TMN card in the phone it would not connect (no service) to any service provider (Bell, Telus, Rogers). If i put the same TMN card in a different phone (unlocked samsung galaxy S2 i9100) it has no issues connecting to either Bell or Telus.

I checked online and read that GSM frequencies of 900/1800Mhz are required for the TMN network in Europe, not sure if while roaming it uses the same frequencies to work here in Canada?

So I thought maybe I need to enable other frequencies in order to get cell/text service with this European TMN sim Card, here in Canada?

I checked GSMarena and compared the two phones; I noticed that the GS4 i337 is missing HSDPA 900Mhz found on the GS2 i9100.

Will enabling AWS also give the GS4 the same 900Mhz as found on GS2?

Question 1: Should I go ahead and enable AWS using the procedure above, will this solve my issue?

Question 2: The procedure is quite straight forward, I also watched one of the youtube videos posted here.. I am however slightly confused on a few points:

Do I need to root my phone before i use this AWS unlock procedure?

Do I need to install that phoneutil.apk (step 2) or not? I already see the "updated" USB settings page when i type in *#0808# into my phone without phoneutil installed.

When I am done with the procedure, should I put the Qualcomm USB settings back how I found them?

My GS4 does not have Kies or Kies Air installed on it; is that going to be a problem?

Thanks for any help you guys can give.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The phone should get at EDGE at least (it supports 900 and 1800 MHz EDGE) if you were to take it to Europe and use the TMN SIM in it. If the SIM is enabled for roaming (it seems to be since it works in your other phone), the phone should connect to whoever the roaming partner is in Canada. Maybe you have the roaming option disabled in the network options?

Also I believe it supports 900 MHz, but it's not listed. It doesn't really matter since in Europe, for 3G/HSPA+ they use 900 and 2100 MHz, but 2100 MHz is more prevalent. That doesn't matter in North America since we use 850 MHz, 1900 MHz, and 1700/2100 MHz (not the same as 2100 MHz) for 3G/HSPA+.

Unlocking AWS will not do anything, UNLESS the roaming partner happens to be a Canadian carrier that uses AWS (which would explain why your phone isn't seeing any carriers). For example, if the roaming partner is Mobilicity or Wind, then yes, enabling AWS would make it work. BUT, the GS2 i9100 doesn't have AWS, so that doesn't seem to be the case. What network does the TMN card connect to when you're using it in Canada?
[AT&T Samsung Galaxy S 4 General] mr_interested:
Hello, thanks for the feedback.

As i mentioned in my post, I can use the European TMN Sim card here in Canada on an older GS2 i9100 phone and connect to Bell or Telus (either automatically or manually selected).

When i try the European TMN card on the GS4 i337M here in Canada, I can see various providers under Network Operators (Bell, Rogers, Telus,) however it will not connect to any of them. (either automatically or manually).

I ensured that all the features within Settings/More Networks/Mobile networks were all set the same on both phones. So i am at a loss as to why the European card will not work on the SG4, but it works on the SG2.

I may try this procedure and open up the AWS bands just to see if it may help, however i am a little hesitant to do so given my other questions on the procedure.

Thanks again for your input.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Neither Bell nor Telus use AWS for their networks (AWS just means 1700/2100 MHz; it's just a name for the combination of those two bands. E.g. 1900 MHz = PCS). And like I said, your S2 i9100 does not even support AWS in its hardware.

Also, could it be that your S4 was marked as lost or stolen? Because not being able to connect to a network is an indicator.
[AT&T Samsung Galaxy S 4 General] mr_interested:
I follow your thoughts exactly on the AWS, and realize that the GS2 also does not have AWS support.

I understand that AWS is 1700/2100Mhz, I was just not sure if this procedure does more than unlock AWS, and if it also unlocks other missing frequencies as well.

My GS4 phone still works on my kodoo plan so i doubt it was marked as lost or stolen. The phone is only around 2 weeks old, and was bought brand new from walmart with the recent Koodo promotion. I did buy an unlock code from an online provider, however you would think that they would avoid marking it as lost or stolen since that would defeat the whole purpose of getting the phone unlocked to work on another service provider in the first place.

How would i even go about checking if it was marked lost or stolen by the unlock provider?

Is this something my local koodo service rep would be able to check?

I have not been able to test any other Canadian carrier since i lack a smaller Canadian sim card.

I do have a larger Bell sim card that i use in the GS2, and i don't want to risk damaging it by cutting it down.

I may take my GS4 phone to the Bell store and ask them to try it out with a smaller card and see if the carrier unlock process actually worked.

I think the carrier unlock worked fine since it no longer asks for a Carrier Unlock code when i insert the TMN card into the phone, however as i mentioned it just does not want to connect to one of the local carriers with this card, it always gives an error saying could not connect try again later.

Thanks for your thoughts.

[AT&T Samsung Galaxy S 4 General] mr_interested:
I was able to test my GS4 i337M and verify that it was indeed unlocked and working using a local Bell and a Rogers Sim Card.

So right now this GS4 phone works fine with Telus/Bell/Rogers.

However it still wont work with this European TMN sim card (which works fine in an unlocked GS2).

So i am at a loss as to why the European TMN Card wont work on this GS4 i377M phone.

Any ideas on where I might find an answer to this issue are appreciated.

Thanks in advance.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Sometimes SIM cards can lock to a specific phone/IMEI. I'm not sure if TMN uses that, but it could be that.
[AT&T Samsung Galaxy S 4 General] mr_interested:
Ok that is interesting, I was not aware of that possibility.

I may try the TMN card in yet another different unlocked phone and see if it also has issues, if so maybe an IMEI lock is a possibility.

I will also see if i can find a long distance or Canadian contact phone number for TMN customer support, and see if they can shed some light on this issue.

Thanks for your thoughts.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
No problem. I had an S4 i337 once upon a time and have used it abroad, so it should work if nothing else is stopping it.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
The phone supports 2G and 3G fine, but no 1800 MHz for LTE. Only 2100 MHz (Band 1. 1800 MHz = Band 3).

http://www.samsung.com/us/support/owners/product/SGH-I337ZWAATT#specs

It could be that your phone keeps trying to connect to LTE? AT&T removes the network mode menu from their ROMs, so if you're rooted, try and flash a T-Mobile/International LTE model ROM and see if you can force HSPA+.
[AT&T Samsung Galaxy S 4 General] JAlfredoP:
For band menu in att try dial code *#2263#
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can do that but if you choose a preference the phone will ONLY use that Band, and only data will work (no calls/texts). Just flash a T-Mobile/International ROM
[AT&T Samsung Galaxy S 4 General] chossen:
Thank you for the support!!!!! I will try it, can i find the rom on xda or samfirware?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You don't want one from Samfirware because those include modems and bootloaders, and for the North American models, you can’t flash a different phone's bootloader/modem because you will brick it/lose IMEI.

I337 has a locked bootloader. But depending on what version of Android it's running, you might be able to root it/ROM it anyways. What baseband and Android version is yours on?

Hello, the phone is rooted and here is the baseband

If im correct, all i did was simplify the method used to open AWS on the newer s4 roms by providing the correct number value to be replaced in the data table.

I have also moved over to insane Kit Kat 4.4.4 rom and the rom runs amazing on my s4. The newer Tmobile rom was having issues with music skipping and what not.
[AT&T Samsung Galaxy S 4 General] _eroz:
Do the steps need to be done with an AT&T SIM? The reason I ask is I performed the steps with my T-Mobile sim and I do not see the speeds that other users see in my area.

When I go to the service menu and I chose any thing besides wcdma/gsm or automatic, I get edge speeds or no service.
