I figured that out and i also tried to fix the problem using his method but for some reason i cant make it work. I flashed the new NE3 modem and followed the guide to enable the AWS but nothing. Im still at wind away and no service. Im at lost right now. This is the only phone i have. WIND network was working before then i flashed the offical 4.2.2 stock rom to fix the update issues ever since i flashed 4.2.2 stock.I have tried every method to make it work, Its been 3 days now and i don't have any service. I also rooted my phone and installed cwm but I don't know whether 4.4.4 aopk build will work for sgh1337m. Its a rom build for another model gs4.
[AT&T Samsung Galaxy S 4 General] Assolute:
So I followed all the steps, it all works and it reboots once I'm finish but when I go to search for networks to see if the Wind network would appear, it doesn't. Any clue what I'm doing wrong? I can only see Fido, TELUS and Bell on my list. I have a Samsung Galaxy S4 1337m originally with Rogers, unlocked.
[AT&T Samsung Galaxy S 4 General] ma678:
I'm afraid you guys haven't applied the mod successfully yet.

I only did it once after I unlocked my Fido i337m with stock 4.2.2. It survived after I tried various Roms or modems. Now I run Golden Eye TW with NE3 modem. I only see Wind and three Wind Away under Network Search; however, it doesn't prevent me from using Wind's network.

I'm not sure what you did wrong. Probably you have to follow the instructions and redo the mod few more times.

Good luck.
[AT&T Samsung Galaxy S 4 General] mal124:
can you provide me the link for 4.4.4 and can I use it on sgh1337m.
[AT&T Samsung Galaxy S 4 General] toysareforboys:
Yep and yep: http://direct.xda-developers.com/showpost.php?p=47755873

Runs SO fast, battery lasts forever. Love it to bits. Quite different from the "touchwiz" that came installed stock on my phone so takes a bit to get used to.

Hay guys thanks for your help I finally got AWS working now I'm on Wind Home. And for those who are not getting it right you need to re read the guide and also look at the pictures too. The person who's is showing you the steps he is extracting the 337 AWS qnc file in downloads folder not the desktop. I followed the steps and pictures exactly and it worked. Just remember one thing once the phone reboots go back into the dial pad and type in *#2263# and select WCDMA Band Preference from there select 1700 and then press menu button at bottom left and then select back to select the 1700 band you will see star symbol beside 1700* . This may or may not help but it sure helped me. Thanks
[AT&T Samsung Galaxy S 4 General] dr_pepper:
Ya - done several times. ZERO errors when performing. does the backup as its supposed and succussfully downloads with no errors. Just when I go into network operators I only see the big 3. No wind.

---------- Post added at 07:14 PM ---------- Previous post was at 07:07 PM ----------

ok - so finally stuck in a wind sim card and now under network operators I see "wind away" 3 times and "wind" once. Go into APN and enable the wind APN and get 4g. So what does all that mean? Wind is apparently working and yet when my rogers sim is in I don't see it listed under network operators. Thanks for the guide anyway - if anyone can chime in with similar experience or explain is appreciated.

Anyone reading............CRUCIAL step to test your success would be to change your Band preference. I'll save anyone else the hassle of deciphering this thread.

TO TEST AWS"

Dial *#2263#

Select "WCDMA Band Preference"

Select 1700 to only see wind and mobilicity

or WCDMA All to see all 5 canadian carriers

IF YOU LEAVE IT AT AUTOMATIC.......YOU WILL NEVER SEE AWS CARRIERS. But if you put in one of their sims your phone will work.
[AT&T Samsung Galaxy S 4 General] Assolute:
I did that, set it to WCDMA All and it worked!

Thanks a bunch, I was wondering why it wasn't showing up but I definitely missed that step. Excited to swap over to wind in a week when my Fido prepaid runs out, good thing the BTS plan got extended til the 15th!

MF3 update

Hi everyone, I have read what I could of this thread. Although I am still a little unclear about what my options are, Im hoping to get some help. I currently have an ATT rooted MF3 GS4 with the AWS hack I previously did.

I have stayed on this version because I want to maintain the AWS compatibility for TMobile, alhtough I am not sure how much that matters now with the LTE support already there and Tmobile moving to PCS for HSPA anyway.

With that being said, Id like to know if theres an easy way to move to to the newest version of Android without messing up the AWS compatability too bad, I think my situation is a little diferent because I would have to use ODIN Im sure to flash since normal updates dont install because I am rooted.

any help would be appreciated.

The phoneutil.apk does not work on Cyanogenmod (11 that I"m using). However if you pop in an AWS carrier's SIM, you will have access to their network. Do not need to select bands in the phoneutil.apk

[AT&T Samsung Galaxy S 4 General] dhomas:
So long as you restore via safestrap (and not Odin) without flashing over the modem, it will work.

I myself flashed a GPE ROM, then realized I had no access to AWS bands. So, I flashed the MF3 modem, but the hack only works on touchwiz. I then flashed a touchwiz ROM, applied the hack and flashed back to my GPE ROM. I'm happy to report, everything is working great for me on Videotron now. :)
[AT&T Samsung Galaxy S 4 General] Penguyen:
Finally got it to work on my Rogers S4 (i337M). I was on OmniROM (4.4.4) with baseband NC1. Did a nandroid of Omni and used odin to restore back to Stock 4.4.2. After that I just followed the procedure (instead use *#0808#) and my Wind SIM worked after.

Can't access *#2263#

I have a I337M unlocked from Koodo. I had a custom 4.4.4 GPE rom, the mod wouldnt work, so I downgraded to 4.4.2 NC1 from SamMobile website. I flashed and got Knox security issue with wifi, I then reflashed without the Auto-Reboot, then I flashed the NC1 modem twice (first time without Auto-Reboot ticked, then reboot phone manually). This got me my Wifi, I then proceeded to do the mod and I think it worked?

HOWEVER<

I can not access the *#2263# (I used to be able to when the I had an mk6 bootloader but now it is an I337MVLUFNC1)

When I go to see Available networks, only Koodo, Bell, Rogers and Videotron are showing.

I do not have a Wind Sim Card yet.

[AT&T Samsung Galaxy S 4 General] victoriousbig:
For anyone who has the Canadian variant(i337m), this is what I did and it worked perfectly:

1. Flash the modem file for the MK6 modem using Odin, make sure that autoreboot is switched off.

2. Put the Wind/Mobilicity SIM in your phone.

3. Follow the steps That have been posted here ( I used the rndis setting and it worked fine)

---------- Post added at 04:14 AM ---------- Previous post was at 04:09 AM ----------

Try to flash the MK6 modem, your wifi and everything else will still work fine, but you will be able to successfully use wind sims this way. Using this guide on NC1 modem will not enable the aws frequency

So are all NEWER Canada Bell Phones fully compatible With Tmobile/MetroPCS on band 3

I also cannot for the life of me get my phone to show up as a port in the device manager (8.1 desktop).

do i need to revert back to stock Touchwiz for the dialer codes/prt issue to be fixed?

Also, if i do do that, will i lose the aws enabled function, if a re flash a different non touchwiz rom after?

Enabling AWS on i337M - QPST doesn't recognize it at the COM Ports

Trying to enable AWS on Unlocked Rogers i337M. QPST keeps showing it as No Phone.

Tried every possible thing but QPST does not see it on COM Ports. Phone was on NE1, I Odin Flashed it to NC1 but no use.

Tried different phones and all are recognized the second they are plugged in except this one.

A week ago I enabled AWS on the other i337M Roger's phone that was doing the same thing (Not being recognized by QPST) but can't remember what I did, that QPST started to recognize the phone and still does when I plug that phone in.

model SGH-I337

bootloader I337UCUFNB1

android version 4.4.2

baseband version I337UCUFNB1

build number KOT49H.I337UCUFNB1

mostly i am on edge. every now and then i get 4G LTE. so i figured it would be good to enable aws.

during restore i get QPST Received an invalid command from the phone

do i need to flash back to an older rom or modem or something to get this to work?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
MF3 or older modem only for the AT&T model. I'm not sure if you can still do this (because of the locked bootloader), but you can also flash a T-Mobile S4 ROM if you want Wifi Calling. When I had an AT&T S4, I was rooted with Loki, so I was able to flash anything. But with the newest official updates, I don't think it's that simple anymore.
[AT&T Samsung Galaxy S 4 General] ozoneaction:
Thanks for reply Fred! In the interest of science I gave flashing the MF3 modem a try but odin gave me a fail. I have another phone I can use on Tmobile in the meantime. So maybe I will wait until one of the developers comes up with a new method or you think this would be an OK phone for straight talk? One more question....is there anything I can try if *#7284# doesn't work? (ha this last question is a joke ;))
[AT&T Samsung Galaxy S 4 General] sonny21:
1. dial *#9090#

2. select [2]DM/DUN over HSIC

4. QPST should detect the S4.

I am not sure if that will work, so do it at your own risk but I know that method has worked for those that QPST doesn't recognize the com ports.

NJ4 to MF3 downgrade ??

I have been unable to get this to work on i337 with 4.4.4 loaded tmobile rom using build NH7.

When i flash the modem back to MF3 with safe-strap i lost cellular reception but wifi and bluetooth still work.

QPST will see the phone however the program will show back and forth between no phone and (0) and not stay on (0).

Just to make sure it wasn't a driver issue i then connected the phone to QPST with the NJ4 modem installed and the phone stays connected fine, however the aws file cannot be applied to this NJ4 baseband.

I use wifi calling and was geared toward tmobile bassed roms for the wifi calling feature. however i had problems finding tombile based 4.3 roms that would boot correctly with safestrap. is there any suggestions for what im trying to accomplish

Thanks much.

UPDATE:

Ok I was able to update the aws file using QPST after I safestraped to the Joseph230_V1.0__Fenny_V1.3_STOCK_M919NB4_for_I337NI1 (tmobile rom) 4.4.2

I was previously on the

M919_NH7_for_I337_NJ4 (tmobile rom) which is the 4.4.4 rom.

This was the NJ4 and for some reason I could not stay connected to the QPST program after the MF3 downgrade modem flash. However when changing roms to the NI1 Fenny 4.4.2 rom then flashing down to MF3 modem, the QPST stayed connected and file upgrade worked great. and the phone is working great after flashing the NJ4 module file to regain wifi.

Im not staying on the tmobile roms and figured these are a good place to start cuz im on tmobile. I dumped my apple products to explore android and am crash coursing myself on the methodology to root access capabilities. And also I gave a dude a bottle of Crown whisky for the phone so why not.
