[AT&T Samsung Galaxy S 4 General] Mrhunter13:
I'm still trying to get the mod but this is my phone on mk2 with out the mode finally got in to the menu the code is *#0011# on mk2
[AT&T Samsung Galaxy S 4 General] damastah:
The QPST part has to work. That's where I got stuck
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Big update i mean big

[AT&T Samsung Galaxy S 4 General] damastah:
I Love sexy tech talk like that :P

Edit:This needs to be posted in the OP. I just did mine... verifying now.... YES!!!! 4G!!! On T-Mobile's network 4.3!!!! DONATIONS DONATIONS!!!!!
[AT&T Samsung Galaxy S 4 General] SamdungSpambot:
Just to confirm I recently applied this to a rogers i317m... It was running 4.1.2.... Downgraded to 4.1.1 rogers stock via Odin, unlocked, applied qcn file and ota updated to 4.1.2 and wind seems to be working well

Not going to try 4.3 for now though
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Not sure if I'm misunderstanding but I've said MF3 works on MK2 with AWS mod. I've been running it for a month lol.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Yea I no ..donations donations..lol
[AT&T Samsung Galaxy S 4 General] damastah:
Oh, sorry. It needs to be pinned or something. 64 pages is a lot to go through....
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Before I did this I update everything for mk2 except the modem using the mk2 tar files and the phones wasnt acting right so I fully updated with the modem ...also correct me if im wrong u are on mdl and u can flash watever to your phone...might have said it but u are in a different boat if u on mdl and able to update and downgrade..im official 4.3 not something I could downgrade from like u ..just saying
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
No offense, but if it's still possible to grab the QCN files from the T-Mobile 4.3 update I'd much prefer that to a Frankenstein'd ROM/modem configuration.
[AT&T Samsung Galaxy S 4 General] damastah:
Doesn't really matter, LOL. It's just numbers...
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Funny name for a rom..I used rock ratt i337 mf3 modem...I was really close to it yesterday I had the phone in my hands the downer they didnt update to 4.3 and they was about to leave sucked...all we need is a willing person thats going to share there qcn file
[AT&T Samsung Galaxy S 4 General] damastah:
That not a rom name, he's saying he doesn't want stuff from different versions on his phone.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
aw ok well i dont care about the phone being mod i just wanted my phone to work on the network...it sucked not having 4g /4g lte on the phone
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Oh I see what you were saying. Yeah, I'm on MDL bootloader, so I can flash back and forth. Nice that you got it working with SafeStrap.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Yea thanks...PPL HIT THE THANKS BUTTON FOR MY HARD DISCOVER ..LBS
[AT&T Samsung Galaxy S 4 General] Tsuul:
I think this is a rediscovery.

I'll hold out for 4.3 QCN
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
I havent seen this no where else
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
Possible downgrade method

I have an Idea about possible downgrading from mk2....so we no u can put the mf3 modem on a stock rom with the help of safe strap so if thats possible y not being able to flash a stock rom zip. like mdl and install it in the stock slot and that will over write the stock slot...and reboot and be back on mdl then uninstall the safe strap recovery ..but the question is the boot loader thats when having the stock odin.tar file to flash back... i say the odin tar because the tar looks for the signature for the software ..and if the phone is already stock but just the bootloaders different it would be flashed with the odin tar.

I think this could be possible because i have read where ppl had to odin they phone bk because they deleted the stock slot in safe strap so what yall think
[AT&T Samsung Galaxy S 4 General] damastah:
The bootloader is everything...
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
that kills that...I want aokp...lol
[AT&T Samsung Galaxy S 4 General] damastah:
Lol. Can't you get it? Isn't that what the rom slots are for? Install it in a second slot...
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
nope ...its the bootloader and its the kernel their roms that stop that 1 only tw...i dont understand how that was aboutto get the aosp gpe on the phone and that was the only 1
[AT&T Samsung Galaxy S 4 General] isa.ahmed:
s4 internationl

i have S4 LTE international one, but is blacklist in AWS so the LTE is hidden from me, but if i use 4G toggle app, i can camp on 4G LTE

any way i can enable it ?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
That makes no sense. And no you can't enable AWS on an international S4 as the 1700 MHz band is US/Canada specific.
[AT&T Samsung Galaxy S 4 General] SDRebel:
trying to figure it out. I'm on MDL (flashed from MK2). is MDL good enough to follow the method in OP? it doesn't really specify anything.

I have the files in my computer from when I did it a few months ago with the first s4 I had
[AT&T Samsung Galaxy S 4 General] Product F(RED):
It'll work on modems up to MF3. If you're in a 4.3 ROM I suggest MF3.
[AT&T Samsung Galaxy S 4 General] SDRebel:
can you guys help us (noobs) a bit more by clarifying steps?

I'm on mdl model (to sim unlock) but on 4.3 MK2 stock i337

i'm very confused as to what I have to do to use this method.

also, I do have the qpst files and the other stuff from last year, when I did it to an older att s4

---------- Post added at 03:20 PM ---------- Previous post was at 03:11 PM ----------

i'm on stock MK2 (with the modem change as mentioned). are you saying that if I change the modem to MF3 I can stay in stock 4.3 and use this workaround?

thanks in advance
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I don't know about stock stuff anymore. My phone is *basically* bootloader unlocked (via Loki), which you can't be running if you took the stock MK2 OTA. If you have a way to flash the MF3 modem, then the AWS mod should work.
[AT&T Samsung Galaxy S 4 General] SDRebel:
seems flashing to MF3 is doable, similar to what I just did to get MDL, though still trying to make sure it is

I got this phone from a friend and it indeed has stock OTA 4.3
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
the work around is for locked bootloaders on stock 4.3 ota like my self and the only sure way of flashing the modem is thru safe strap ...
[AT&T Samsung Galaxy S 4 General] SDRebel:
i've seen safestrap mentioned a few times but haven't read about it yet. out to search for the thread.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
yea safe strap is for locked bootloader so u can flash roms....i think the modem i flashed unlocked the toggles so i was able have the mobile data toggle that was missing heres the link http://d-h.st/ReU
[AT&T Samsung Galaxy S 4 General] SDRebel:
while trying to understand this whole thing, I found the MF3 files here (http://xdaforums.com/showthread.php?t=2573080)

Downloaded the file, extracted and was able to flash the mf3 modem successfully using odin...would that mean I'm good to go or not really? I was a bit afraid it wouldn't flash, but seemed like flashing back to mdl or mk2 would fix the soft brik or loops...

what do you think?

not really sure if I only need the modem or also the stock mf3
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
if it works for u thats good...before i did the work around i had updated everything but the modem with odin and i was having issues with the phone not connecting to the internet and calls ...they say a factory reset from stock recovery but fix the boot loops
[AT&T Samsung Galaxy S 4 General] SDRebel:
actually, i was just going to try the aws mod, but *#7284# didn't work and haven't been able to find a workaround. also, the full access to the menu with *#0011# (then menu-back, input 1) seem s to have gone away as well, so seems i'm not good to go with this :(

at least no brick or reboot loop or anything
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
the code is *#0808#
[AT&T Samsung Galaxy S 4 General] SDRebel:
woah! that was the key. i had searched for like 30 minutes wtih no luck.. I was able to do the mode with MDL (i did go mdl, mf3, tried mdb, mdl again).

now I need to test it for aws band, but everything went fine. you da bomb :)

edit:

confirmed band4 umts (AWS) now enabled :whee: :whee:
[AT&T Samsung Galaxy S 4 General] damastah:
That was totally in the Q&A forum and here. Lol.
[AT&T Samsung Galaxy S 4 General] HORiZUN:
So I've SIM unlocked, and now enabled the AWS spectrum on my S4. The thing is, only AT&T adn Verizon have 3G/4G/LTE in my area. T-Mobile ONLY has Edge in this part of the state. The closest 3G/4G/LTE for T-Mobile is over 60 miles away.

Will this benefit me at all being an AT&T subscriber, or is this mainly for when I tell AT&T to shove it and go back to T-Mobile? (with my AT&T handset, of course) :)
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Won't help you at all if you're on AT&T because they don't use AWS HSPA+
[AT&T Samsung Galaxy S 4 General] skavis:
I just read this entire thread. Not some of it. All of it

Was on Fido with an i337m in Canada. Was not able to get wind coverage.

I did this mod on an omega v19 ROM with Android 4.3 and an mk6 modem

It worked. And I'm currently now a wind customer. So I can confirm it works.

Some notes

Take out your Sim card before doing the mod

The code is *#0808#

Change it back to mtp+adb when your done

The question now is thus

I am getting reception with calls. apn settings pushed through automatically.

However all I am getting for data is hspa (h+)

Is there any settings I need to change to get 3g or 4g

Please help
[AT&T Samsung Galaxy S 4 General] damastah:
You don't like HSPA+?
[AT&T Samsung Galaxy S 4 General] skavis:
Well I must admit I am a bit ignorant when it comes to speeds. I was under the impression that h+ was slower than 4g but after doing some reading I'm thinking that's not the case.

Problem is and was is that the connection is spotty. Speeds are only 2-3mbps at best and it drops in and out.

Is there anyway to switch back and forth or is h+ the way I should go?
[AT&T Samsung Galaxy S 4 General] damastah:
Yeah. H is 4G, H+ is 4G LTE. You always want the fastest speed you can have. Although a bad connection to a 4G tower is worse than a good connection to a 3G tower, they usually get it right.
[AT&T Samsung Galaxy S 4 General] GuyIncognito721:
Nope.

4G - LTE (4G)

H+ - HSPA+ (3.75G)

H -HSDPA (3.5G)

3G - UMTS (3G)

E - EDGE (2.5G)

G - GPRS (2G)
[AT&T Samsung Galaxy S 4 General] Product F(RED):
We're talking in terms of notification bar icons only. 4G encompasses everything between EDGE and LTE.
[AT&T Samsung Galaxy S 4 General] cpoldedana:
I have a rooted i337 with Region/Sim unlock so when I go to France and the UK this summer I can pick up a local SIM card and use my phone. Will doing this mod give me any benefits in those countries or will it be fine just leaving it alone? I still have over a year left on my contract with AT&T so no need to do this now locally.
[AT&T Samsung Galaxy S 4 General] damastah:
Only if they have aws over there
[AT&T Samsung Galaxy S 4 General] Product F(RED):
No. AWS is only used in the US and Canada. Europe uses 900 and 2100 MHz for HSPA+ (supported out of the box). They use 800/1800/2600 MHz for LTE (i337 supports 2600 MHz out of those for LTE).
[AT&T Samsung Galaxy S 4 General] cpoldedana:
Thank You. So if I'm unlocked and region removed (Never real had that as my manufacture date was 5/10/2013 which is prior to July when they started locking them by region) my phone should good then?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Yeah you're fine dude. At the very least, you will get EDGE and HSPA+. I've taken my T-Mobile Note 2 and AT&T Galaxy S4 (both support the same bands except the T-Mobile Note 2 has that additional 1700 MHz that is unused in Europe), and they both worked fine in Austria, Germany, Belgium, and Ireland.
[AT&T Samsung Galaxy S 4 General] cpoldedana:
Great! Thank You!
[AT&T Samsung Galaxy S 4 General] oung:
hey guys im wondering if i need this mod? i have my att galaxy s4 unlocked to tmobile but i do pick up LTE 4g signals where ever its available....so is doing this more benefitting me? i've tried to do this method but everytime i go to to restore, and try to restore the aws qcn it stops at 5% and gives me that "error recieving command from phone"...any help if i do need to do this?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
1. What it does is give you 4G in areas that have only 4G but no LTE (because those are usually the areas that use 1700 MHz). If you're fine as you are, then there's no reason to do the mod.

2. You would need to be on MF3 or earlier modem (MF3 highly suggested if you're on Android 4.3). On MK2 modem or higher, the mod will fail to flash as it did for you.
[AT&T Samsung Galaxy S 4 General] cpoldedana:

[AT&T Samsung Galaxy S 4 General] Solace50:
then you probably misread the important parts where the mods intended for 4.2.2 modems, its unknown if the memory offset is the same for 4.3 modems and the patch potentially overwrites other data. flash a mk5 modem its essentially the same thing from wind.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Alright so not to be a jerk, but stop PMing me saying you have an MK2 QCN but refusing to send it to me. I'm tired of getting close to making it work on newer modems but not actually getting there because nobody wants to send the damn file. I don't now why it's so hard. If you don't want to send it and you don't want to flash it, then keep your mouth shut.

Not pointed towards anyone in particular.
[AT&T Samsung Galaxy S 4 General] Mrhunter13:
LOL that's funny
[AT&T Samsung Galaxy S 4 General] skavis:
I know the patch was made for 4.2.2 but I flashed it on a 4.3. Are you saying the mk5 would show 3g and 4g? I thought H+ was the same thing and its what shows under the wind network instead of 3 or 4g (I did some more reading elsewhere)

"flash an mk5 modem its essentially the same thing" - Same thing as what?

My post was to tell people that I was on an mk6 and the patch worked. Which is exciting!

I recently was playing with my custom rom and screwed my phone up. So I had to go back to stock with odin.

Odin stock rom for rogers with mg1 modem.

PATCH STILL WORKED

Just updated back to omegav19 4.3 with mk6

PATCH STILL WORKING

Now I can't say that any of this will work for anyone else... but it worked for me.

i337m with wind running omega v19 for i9505 and an mk6 modem

Thank you to the original people behind making this patch available. Brilliant stuff.
[AT&T Samsung Galaxy S 4 General] Solace50:
your definition of "working" is skewed if your post involves asking for advice on issues present due to the patch. just because you get some form of connectivity doesn't mean its in a conditional state for everyone. i would expect the 4.3 patch when provided to work on the mk6 modems without issue due to the variation is minimal. not so certain about the us based modems though.
[AT&T Samsung Galaxy S 4 General] Amb669:
if i'm NOT on an LTE network i get network drops when I turn my screen on

for example:

LTE/WCDMA/GSM= no drops

WCDMA/GSM= network drop when screen turns on

WCDMA= network drop when screen turns on

GSM=network drop when screen turns on

I recently did this unlock on my i337m (MVLUEMK6) so I could use wind and since wind doesn't have LTE I get this 100% of the time I turn my screen on, with bell sim I get the exact same results UNLESS i'm using LTE/WCDMA/GSM= no drops

I've tried using *#2263# and manually setting the bands to WCDMA 1700 (which i'm pretty sure is wind's AWS band in canada) but I still get network drops

this affects both stock rom and the one custom rom I've tried, any ideas what's going on with my phone?
[AT&T Samsung Galaxy S 4 General] ojaybock:
W00t! It WORKS!!!

First off, thanks! This worked!!

Here is what I did:

Rooted and installed safestrap (look this up)

Downloaded the MF3 modem: http://xdaforums.com/showthread.php?t=2324667 (6th one down)

Copied that to SD Card

Rebooted into recovery (safe strap)

Confirmed I was on the stock ROM slot

Chose install and chose the ZIP I downloaded earlier

Rebooted after it finished

Confirmed that baseband is MF3

Put phone into the QPST mode (*#0808#)

Chose RNDIS + DM + MODEM

Hit OK

Used QPST, backed up existing QCN data

Flashed new QCN data from here: http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/

After a reboot placed a call from my desk phone to confirm it switches from LTE to 4G and it did, PLUS I was able to use DATA and TALK at the same time! <-- this part was huge btw

Hopefully that clears up the steps, and thanks again for posting this! It worked great.
[AT&T Samsung Galaxy S 4 General] aeba7:
I can confirm that this worked on my Canadian S4 (Rogers).

Details (in order):

-i337M with 4.3 MK6 out of box

-Rooted using CF Auto Root, flashed CWM

-Unlocked using code

-Performed AWS mod

-Flashed CM10.2

No problems as of yet;

-voice,text and data works

Will report back in one week's time if I encounter any issues.
[AT&T Samsung Galaxy S 4 General] Ziida:
Just got an S4 i337 (AT&T) model from eBay. It came in seemingly unmodified on an MDL baseband, android 4.2.2.

-Failed to Root on CASUAL (likely my fault, lost USB connection), but recovery installed. Finished installing root on MotoChopper.

-Sim Unlocked using RegionLock Away, but failed to region-unlock. (Phone stopped asking me for unlock code, but was unable to connect even to make phone calls)

-Successfully unlocked AWS bands using the method outlined in this OP's post.

Overall great success. Thank you, DEVs !! :D

edit: Just wanted to mention that though QPST seemed to successfully make a backup file to it's default directory in my Program Files, I couldn't find it there when I looked. Reran backup up to my desktop and that was a success.

[AT&T Samsung Galaxy S 4 General] Ziida:
After running this process my phone hasn't mounted as a media device. It seems like it's still trying to mount as a port / network adapter and whatnots.

I have tried uninstalling QPST and phoneutil.apk with no luck yet. I have also disabled developer options and usb debugging.

Can anyone tell me what I'm missing here?

EDIT: well after trying to erase the drivers a few times I finally tried factory resetting the phone and now it mounts fine. Still AWS-Unlocked as well :)

Hey guys did you experience any problems making calls, the only thing that doesn't work for me is calls, can not dial out...Data works, text works,. Some aps were FC, that was fixed after I did a reset but still can't dial out. Will the MOD stay if I change back to the MK2 radio???

Confused

First time poster long time lurker. Thanks everyone for all your helpful tips and tricks, great community here.

I recently switched to tmobile from Att. Sim unlocked from Att and an now on mobile network.

I would like to enable the band's on my phone but I'm not sure who's instructions to follow. I see the op instructions then there are others throughout this thread some with safe strap etc. Which method should I follow? I don't want to screw up anything.

Here's my info

Stock 4.3

Baseband and build are mk2

Thanks everyone in advance.
[AT&T Samsung Galaxy S 4 General] ojaybock:
I can confirm the instructions that I gave above are still working 100%

The S4 switches between LTE and 4G when needed instead of LTE and Edge like before.

The only thing missing from the TM variant is the WiFi calling...which to be honest isn't a big deal to me.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I'm running a T-Mobile ROM on my S4 which has Wifi calling. Wicked v10. I'm loki'd on MDL bootloader so I can flash whatever I want. Not sure what you should do if you're running Safestrap.

Wifi Calling is actually great because it sends call texts and MMS over Wifi. That also includes when your overseas, so everything counts as domestic.
