After trying it like 30 times on my att s4 sgh-i337 4.3 BASEBAND I337UCUAMF3 BUILD # JSS15J.I337UCUEMK2 with a simple mobile sim card

I still can't get 4g all I get is "E" and my phone's internet connection is soo slow. Any help please :(
[AT&T Samsung Galaxy S 4 General] Product F(RED):
If it flashed successfully and you're still only getting EDGE, you're probably in an area with only EDGE. Didn't Simple Mobile add LTE recently? So no LTE and no 4G. Where are you located?
[AT&T Samsung Galaxy S 4 General] fcolon76:
Springfield MA I just redid it all over again and instead of messing w the settings I left them untouched and now i'm getting LTE THANKS :D

I am using PuriFied Rom for safestrap. I did a speedtest and got lower numbers than what I expect on TMobile. I am on Ultra Mobile, a TMobile MVNO currently.
[AT&T Samsung Galaxy S 4 General] sirobelec:
Lemme ask a really dumb question.

I'm in Eastern Europe, but I have the SGH-I337 (don't ask me how xD).

We don't have LTE, but the HSPA+ is available.

Had the opportunity to test against a GT-9505 directly. We were on a train, data conn was on, we're on the same carrier...

But the GT was having HSPA with no problem, my I337 didn't go above EDGE.

If I do this AWS unlock, will I be able to reach HSPA+ in more areas? I travel a lot, but outside of cities I rarely reach HSPA speeds.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I don't think so. AWS (1700+2100 MHz together) are only used in North America and I think parts of Asia. It might be because there's no 900 MHz. I think US carriers except for Verizon and Sprint have been turning off 900 MHz because it's not used in the US.
[AT&T Samsung Galaxy S 4 General] MAFU21:
This need root??

Sent from my SGH-M919
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
No, unless you're on mk2 or later. Then you need to root and flash the mf3 modem in safestrap.
[AT&T Samsung Galaxy S 4 General] jjjooonnn:
What do!

Here's your first noob question... pls help :crying:

How you do this?

By the looks of this post you can only flash a modem with the same firmware (?)

They also mention needing the right "nonhlos.bin" flashed, did you have to mess with this?

Did you just use: root, TWRP, and Odin to flash UCUFNB1 over to MF3 and proceed w/guide like normal?

:cowboy:

I'm at my wits end.

Baseband: I337UCUFNB1 (Build Number: KOT49HI337UCUFNB1)

4.4.2 Kernal 3.4.0-50595

EDIT:

Ok.... did some digging,

Looks like you'll need to:revert to 4.3

Then flash to: a pre-rooted 4.4.2

And then safestrap will allow: a mf3 modem to be flashed on 4.4.2

Then you follow this guide and: praise the forgotten gods.

I haven't tried this yet, but I'm in for a long night.

Here's some good info: All things AT&T MK2 and NB1 (including ROMs)
[AT&T Samsung Galaxy S 4 General] golgiapp:
Just saw you edited this... but yes - flash the zip in safestrap. You can go between modems and there is one that is already AWS modified too.

I actually found little difference between the AWS and the latest and greatest so I just stuck with the latest and greatest. Good luck to you and here's the modem thread.

I got the QPST to recognize my phone at first try...but I wasn't able to upload the 337_AWS.qcn...I noticed that I needed to unlock my phone, which I did via network code I purchased online, but now QPST never recognizes my damn phone anymore! I've tried it on two different PCs...all the same steps, even installed and updated Kies...any ideas?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
UltraMobile doesn't offer LTE as far as I know. Just because they run on T-Mobile doesn't mean you'll get LTE.
[AT&T Samsung Galaxy S 4 General] pspTP:
Thanks. They advertise 4G data on their website, and I was not seeing that either except 3G or H+ so I was wondering. I now have reset the phone back to stock firmware, ran the debloater tool and removed a bunch of crap. Now it shows 4G all the time on stock MK2. Wonder if that's real!
[AT&T Samsung Galaxy S 4 General] Product F(RED):
H+ = 4G. 4G just means "HSPA+". You seem to be running a ROM that shows the real signal icons. Carriers here in the US like to brand 3G (HSPA+) "4G" to make it sound like it's faster. When you see "3G", that's the modem going to sleep because it's not being used. H+ means it's on and being used.

I got the QPST to recognize my phone at first try...but I wasn't able to upload the 337_AWS.qcn...I noticed that I needed to unlock my phone, which I did via network code I purchased online,

QPST 323 never recognizes my damn phone anymore! I've used a newer build, and it recognizes it, but when I wanna download for backup, or upload the AWS enabled firmware, it said it can't write the update. any help?
[AT&T Samsung Galaxy S 4 General] ma678:
What firmware do you use right now? Some people say this method doesn't work on 4.4.2.
[AT&T Samsung Galaxy S 4 General] bananaxr:
Hmmm what method can one use with 4.4.2? I see a lot of people offer the service for $15 even with KitKat.

thank you so much for the reply.

It's actually running 4.3. It's SGH-I337, vaseband version I337UCUEMK2...any help?
[AT&T Samsung Galaxy S 4 General] ma678:
Your firmware is supposed to work with the mod wothout any issue.

Please read through the whole thread because someone also had the same problem. It sounds to me USB driver wasn't installed properly. Are you able to do it via different computer?
[AT&T Samsung Galaxy S 4 General] MetaLRasaM:
I tried it on three different computers! prior to unlock, build 323 worked just fine, but wouldn't upload the modified file, and then I realized I need to unlock my phone. So I did. After that. I haven't been able to get this build to see the phone. A newer version actually sees the phone on the port assigned it, but it says it can't write! I've attached a screenshot...It's driving me nuts. I also installed Kies just for the drivers, figured maybe that's the case. I did search the thread, couldn't find anything, I'll try again.
[AT&T Samsung Galaxy S 4 General] MetaLRasaM:
As you can see, on the same PC, with same drivers, the newer build recognizes the phone just fine, but upon downloading or uploading the files, I get this write error. It's not a disk related issues, I've tried on different partitions and double checked the permissions. Also opened the app with "admin" rights.

edit: upon using a better keyword on this thread, I think I may have solved the issue...I'll update this asap =)

edit 2: Can download!!! so that's good. Can't flash the modem however, it seems that I'm running MK2 and some sort of downgrade is in order...I'm reading a bunch of stuff now.
[AT&T Samsung Galaxy S 4 General] bananaxr:
Well nevermind, the method worked fine for me on 4.4.2 + latest patches on the phone. (i337m on rogers)

Thanks for the great thread!!
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yeah, the i337M is slightly different than the i337. On the i337M you can use the mod on the latest modems/firmware. On the i337, it's not firmware-dependent, but you need the MF3 modem. You'd need Safestrap to downgrade if you're on a newer one. No explanation why, but that's how it is.
[AT&T Samsung Galaxy S 4 General] nappy gamer:
Thank you!

Took me approximately 20 minutes, and i was already making calls on a network I could not detect for days! Thank you!!!
[AT&T Samsung Galaxy S 4 General] dan428:
Indeed, took me hours late night to figure out why I couldn't push the aws enabled qcn to the phone on my i337.. I had a newer modem.. once I installed safestrap and flashed mf3, it worked without a hitch! I can't confirm whether aws works yet because I was already in lte service at home, but I presume it does.

If I hadn't searched thru hundreds of posts in this thread,I wouldn't have figured it out.
[AT&T Samsung Galaxy S 4 General] t322223:
Will it work with international G-i9295 model? or where can I get QCN File for international model? thanks for help...
[AT&T Samsung Galaxy S 4 General] Product F(RED):
This is for the AT&T S4 i337 and Canadian S4 i337M. It won't work on any other model, including the S4 Active (both AT&T and International). The reason is because the QCN is an unmodified NV ROM backup of a T-Mobile Galaxy S4 M919, and only those two other models have the exact same hardware and software. We would need an AWS-enabled Galaxy S4 Active, which doesn't exist. Even then, it probably wouldn't work on the international model, just like how this mod doesn't work on the international S4.
[AT&T Samsung Galaxy S 4 General] billykidd13:
works back and forth

So when I load the aws file using qpst I can get wind but when I put back any other sim I get unregistered sim? I can go back and restore old .qcn and get fido but not wind? Is this due to the fact it is 4.4.2 NE1? this is an unlocked i337M model

[AT&T Samsung Galaxy S 4 General] BL4zD:
Does AWS remain enabled once updating back to the current modem?
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
No.
[AT&T Samsung Galaxy S 4 General] BL4zD:
To be clear, that means the device has to remain on MF3 in order to continue using AWS?
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
Just the MF3 modem. If you update your firmware you just have to downgrade your modem with safestrap.
[AT&T Samsung Galaxy S 4 General] RushFan1:
Didn't work. When I typed in *#7284# and hit enter I received the following "Connection problem or invalid MMI code"

Was I supposed to download the QPST software to the phone as well?
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
If you're on stock, dial *#0808#
[AT&T Samsung Galaxy S 4 General] YaKillaCJ:
Ok thanx for being clear. 1 more question. If I updated my modem after doing this by mistake. Will flagging back down to MF3 be enough or do I have to push the QCN again?
[AT&T Samsung Galaxy S 4 General] Duffmantp:
My question, what is the benefit of enabling aws on the attached i337? Is it just to use a att variant phone in Canada traveling from the us?

Then how would this be different then just unlocking the phone and using local Canadian Sim?

I guess I'm trying to understand the benefit of doing this on att s4 US variant.
[AT&T Samsung Galaxy S 4 General] BL4zD:
I think I had to push the QCN again after updating the modem and going back to MF3

I believe if you don't unlock AWS you'll be stuck on edge speeds. At least that's what happened when I unlocked this device to use on tmobile
[AT&T Samsung Galaxy S 4 General] YaKillaCJ:
Well 4g pops up for me even when I was on NC1 Modem. I can't check LTE tho because I actually have Walmart's Family Mobile as my provider which I don't think get LTE to begin with.
[AT&T Samsung Galaxy S 4 General] Thr33-F0ur:
It depends on where you live. In some areas, T-Mobile's 4g is in the PCS band (1900MHz) so it'll work without the AWS mod.

Hello,

I currently have this mod applied to my i337m with firmwares (PDA:NC1, PHONE:NC1, CSC:NC1)... If I update through Kies to the latest firmware (PDA:NE1, PHONE:NE1, CSC:NE2) would this still work? would have to apply it again? or would it completely ruin the mod as it won't be compatible with the new firmware?

Trying to figure out if I should update or no... Thanks.

You have to downgrade the modem to MF3 via Safestrap if you're not Loki'd. If you do have Loki, then just flash MF3 modem normally through recovery and apply the QCN file.

This method worked for my Canadian Bell Galaxy S4 (SGH-I337M) that I bought the day it came out last year.

Phone was already unlocked using cellunlocker.net last year. No AWS though of course.

Was running a 4.4 Touchwiz ROM (Goldeneye) on the MK6 modem and _could not_ get into the dialer menus (neither *#0808# nor *#7284# works).

Did a nandroid backup and installed a 4.3 Touchwiz ROM (Goldeneye 21). Now *#0808# works and I can follow the instructions on the first page. After everything is done, I revert back to MTP+ADB in the *#0808# menu.

I then verified AWS was working with a Mobilicity sim card. Finally I restored my 4.4 nandroid backup and AWS continues to work.

EDIT:

Nevermind found it! Here is the link for everyone to the Goldeneye 21 ROM that apparently works with this AWS activating method. It's a downgrade method from the android 4.4.2 that doesn't work.

*flash the ROM then the i337m fix if you have the Canadian version.

*After typing in *#0808# on your keypad. Start from Step 5 of the OP instructions.

*Make sure to switch back to MTP+ADB in the *#0808# menu after you are done.

*Flash another ROM or the recent version of Goldeneye (35), I can verify that it works flawlessly.
