If you like to use your phone on videotron network, you have no choice but to unlock it first.

I believe in Quebec you are supposed to find Rogers/Fido/Bell/videotron network. Correct me if I was wrong. Public probably uses different network.
[AT&T Samsung Galaxy S 4 General] Masaker514:
Public mobile is cdma here and very crappy. Before i put in the AWS hack the phone never showed videotron. After installing the QCN file it's showing Videtron. The service menu unlock doesn't seem to work anymore. Even though i downgrade the firmware to the one straight out the box. S3's are still able i just did one 2 days ago.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You have to downgrade the modem as well. The modem dictates what options are available in the service menu.

I'm on the MDJ now. I won't update. Question will my phone work if i flash ATT firmware? Modem do you mean baseband version?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Modem = Radio = Baseband (it goes by many names, but on the forums it's generally referred to as the modem). Yeah, you can flash AT&T firmware (I believe). I myself have an AT&T S4 i337 running the MDL modem (AT&T) with AWS mod and a T-Mobile ROM (Wicked ROM 5).

The modem/radio/baseband can be upgraded and downgraded freely. Downgrade to the earliest one for your model and do the unlock. It should work. I believe the firmware also has to be an early one. After you do the unlock, it's permanent no matter what you flash.
[AT&T Samsung Galaxy S 4 General] Masaker514:
Thanks for your help i did downgrade but unfortunatly it is not working on my phone. I even enable sha 256 on then back and hit sha 256 off and get the 116631 command. It's not a big deal just figured i'd try it.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Well if you have a few bucks, you could always purchase an unlock code from eBay.
[AT&T Samsung Galaxy S 4 General] ssss25:
I want to actually run on wind or roamability if I go to states.

I am getting unlocked today. I am on mg1 fido.. Does that mean I have to downgrade modem or is that for at only?

Thanks...
[AT&T Samsung Galaxy S 4 General] Masaker514:
Honestly i'm also on Rogers/Fido. I downgraded to MDJ i am able to access the menu but don't think my phone is unlocked. I only see Videotron after doing this trick. Doesn't hurt to try you don't lose anything.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
The unlock is not the same as the AWS mod. You have to do both.
[AT&T Samsung Galaxy S 4 General] Masaker514:
I did the unlock trick before but nothing happened. I'll buy an unlock code. But mind you i'm not using the sim that should be registered for my phone if that makes a difference for the unlock.
[AT&T Samsung Galaxy S 4 General] ma678:
I was with Fido before switching to Wind. All what I did were downgrading to mdj, turning 256 on, unlocking the phone using a code, adding AWS, and then upgrading to mg1.
[AT&T Samsung Galaxy S 4 General] Masaker514:
That seems like my only option because the sha off isn't working on my phone.
[AT&T Samsung Galaxy S 4 General] ssss25:
OK.. So downgrade to mdj the radio alone? Will that reset my data.. Can I keep my system on mg1 and downgrade radio mdj only.. Then perform steps at the first msg of this thread.. Then upgrade radio to md1 again?

If answer is yes. Anybody has a good link to show downgrade files and instructions. I will Google around.

BTW.. I already got a code and unlocked Sim.

Thanks.
[AT&T Samsung Galaxy S 4 General] Masaker514:
Nothing gets reset i downgraded the whole rom it self and all my apps were still there.
[AT&T Samsung Galaxy S 4 General] ssss25:
Thanks. I decided I want to try this on MG1... as per some posts, I used *#8080# and everything else as per the steps worked OK. So, why do I have to downgrade to MGJ? Maybe it's for the SIM unlock which I already did using buying a code... So, is there a way to find out what frequencies I now have open? I guess I'll just find someone with wind SIM to try.

Any thoughts?

Thanks,
[AT&T Samsung Galaxy S 4 General] Masaker514:
When you go to settings connections more networks and click mobile networks do a search you should have more options to choose a network
[AT&T Samsung Galaxy S 4 General] ssss25:
Oh. Good idea. I didn't try it before but I do see videotron and wind.. I guess it worked ;)

Thanks for ur help guys..

So in summary. If u are on mg1. Unlock using code.. Then use the instructions with *#0808# for the second step and Bob is ur uncle ;)

Hey I need some help, I followed all the steps as best as I can see. I changed it to RNDIS + DM + MODEM, connected, ran QPST and got no phone on all com ports. So I tried setting it to RMNET, didn't work. Tried " *#9090# and hit 2 for HSIC" let it reboot, rebooted computer and changed usb ports and all com ports are still saying no phone.

Possible windows 8 issue?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I had that problem but after I downloaded and installed the phoneutil APK from the OP, it worked. I'm using Windows 7 on my desktop and 8 on my laptop and did it on my desktop, so I'm not sure if it was a phone side issue or a computer side, but there's a reason you have to install the phoneutil.apk from the OP.

[AT&T Samsung Galaxy S 4 General] DeadmanGalaxy:
Not sure if this is the right way but it works..

1. I installed phoneutil.apk

2. typed *#0808# change the settings.

3. tried to connect but all of the ports said NO PHONE.

I tried it over and over and over and nothing. So I started looking around.

4. typed * # 2 2 6 3 #

5. Hit [2] WCDMA Band Preference.

6. Hit [6] WCDMA ALL or wcdma/gsm mode only works great too.,,

7. Backed out.

8. Hit End.

I lost signal then after a few seconds it came back. My Unlocked Samsung s4 at&t on

T mobile with no data is now working. Not sure if it is 4G But its fast and 4G is on the status bar.

I hope this helps. It worked for me. I hope this will work for you as well. Good luck.

QPST problem help!!!

Hi guys! When I install the QPST, it installs 98% and once it hits 99% a pop up window opens up (I have attached a picture of the pop up window that opens up). What is the problem? Is there a problem with the QPST program? I have installed it on like 4 different computers and laptops and I am having the same problem with the QPST. I even downloaded the QPST from a different source and had the same problem. Why isn’t QPST installing?

Any help would be kindly appreciated!

I'm a little confused wehter this will improve my speeds or not. I apologize for the noob question but I'm on rogers with the 1337m and I was wondering if enabling this will improve my rogers signal, or is it just for people switching to t-mobile??

Sorry for the noob question
[AT&T Samsung Galaxy S 4 General] Product F(RED):
It does NOT improve speeds. It just makes it so that you'll get HSPA+ on carriers that use AWS (T-Mobile, Mobilicity, Wind, etc).

Hi Together

I tried to find the information in the thread but i am not sure. I have a AT&T i337 Galaxy S4 with 4.2.2 MF3 firmware. It is rooted and unlocked (via bought code).

Can someone please answer me the following questions:

1. I live now in Germany and my provider (Vodafone) uses 800 and 2600 Mhz. So I need this steps to get LTE right?

2. If yes, can I follow the instructions from post #1 with my phone?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You will never get LTE in Germany with any US variant. You need an i9505. 800 and 2600 are not used in the US.

Sent from my SGH-I337
[AT&T Samsung Galaxy S 4 General] CanadianKB:


Actually I specifically got the m919 because it has the same specs as the Google edition and the i9505 and would run in Canada. Europe. Alaska and obviously mainland USA. It is the only us variant that has all the bands for international late. As for aws I'm not sure on how that works but I know you can enable it on atnt just Google it and look for the thread. Not sure if that's Gona get you LTE though. You could buy a tmobile phone with bad IMEI pretty cheap and use over there or Google edition or get the international obviously! Just wanted to clarify M919 rocks
[AT&T Samsung Galaxy S 4 General] att85:
Oh okay. Can you explain why?

So the guy in this post has not the AT&T Version of the phone? Or he has it, but uses a US provider? Because it was also 2600Mhz.

http://xdaforums.com/showpost.php?p=41750736&postcount=9

Sorry i am a bit confused. Is it because of the bands?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
In the US, for LTE on GSM carriers, we use 700 MHz and AWS (combination 1700/2100 MHz). Europe uses completely different LTE frequencies than the US.

The i337 is the AT&T (US) device. The i337M is the Rogers (Canadian) device.

i337 for LTE is capable of 700, 850, 1700/2100, 1900 MHz

i337M for LTE is capable of 800, 850, 900, 1800, 2100, 2600 MHz according to here: http://www.samsung.com/ca/support/model/SGH-I337ZKABMC-techspecs

The i337 (AT&T model) does the same LTE bands as the T-Mobile model. It only lacks AWS HSPA+ (3G), which the mod in this thread enables. I would have gotten the M919, but T-Mobile doesn't sell the 32GB model, plus AT&T variants are generally cheaper.

No model sold in the US (including the i9505G Google Edition) will do 800 or 2600 MHz. The i337M does though (Rogers Canada). Europe uses completely different LTE frequencies than the US.

The m919 according to this supports 2 and 5 bands that the i337 does not, i am new to this but as i said i picked this phone for international use aswell and would like to know the truth. But according to my information, Vodaphone in Germany uses to main bands 7 and 20. 7 Being the one that the US variant could receive.

since the I337 is basically the same in Canada, i looked up Bell

Bell :

Bell	Canada	1700	4	FDD	September 2011	[75][76]

Bell	Canada	2600	7	FDD	March 2012	[77] available in Kitchener, Waterloo, Cambridge and Toronto for additional bandwidth.

Both 4 and 7 are support by both devices, since 7 is on freq 2600mhz in Canada and is the same I337 as AtnT would it not be right to assume that the phone could get band 7 in europe? It is true that AtnT does not use those bands in the US but that does not mean the phone cannot support them. Furthermore i picked the M919 because of its native AWS support and the 30$ 5GB 4GLTE Tmobile Plan BOYA talk about savings..... I am curious to know if im correct, my research lends me to think I am. Europe uses mostly band 3 and 7! 7 Being the one you want!

[AT&T Samsung Galaxy S 4 General] Product F(RED):
Ok so here goes nothing:

The first time I've tried the AWS mod was on my AT&T Note 2 (it worked the exact same way as this mod for the S4). However it wasn't as stable as it is on the S4, so I traded for a T-Mobile Note 2. Then someone I knew sold me a BNIB AT&T S4 for $300 (yes, three hundred, he was an idiot). I did this mod and continued using the $30 T-Mobile plan that I've been on since May.

So to get technical, the Qualcomm 9215M modem in the Note 2/S4 (they use the same modem) are software defined radios, which means they SUPPORT all of the bands that are in all of the models on a hardware level (including even CDMA!). BUT, the only reason we were able to enable AWS on AT&T models is because the AT&T model is really a T-Mobile model with AWS HSPA+ disabled (AT&T requests Samsung lock it out since it's unnecessary for them).

Now, I am NOT saying go and flash an i337M NV backup onto your device to enable 2600 MHz. It won't work. Because it's a different model. So is the i9505. But the M919 and i337 are the same in the modem memory, aside from a line or two that enables AWS.

Hope that clears things up for you.
[AT&T Samsung Galaxy S 4 General] alus415:
I want to enable AWS for resell value mainly but question if i do enable AWS will it affect my ATT connections, especially LTE and H+? I don't want to replace my ATT 3g/4g bands to enable AWS unless I was switching to T mobile.

Thanks
[AT&T Samsung Galaxy S 4 General] sonny21:
It shouldn't effect it. Very rare cases it might but you should be fine. Also you can just restore your backup if you experience any problems.
[AT&T Samsung Galaxy S 4 General] FireRaider:
Worked so far

I followed the directions carefully and can report that I have no ill effects from the mod. I hope to find a TMO micro sim from someone tomorrow at work and give the speeds a test. I will post back when I do.

I also must say, I cant believe this isn't generating more interest. If I had known this was possible I wouldn't have waited a whole week before buying my GS4. LOL I see huge potential for this with a sim unlocked phone and people who travel a bunch.

Now to see if I can find a dual sim adapter that will allow LTE configurations.

[AT&T Samsung Galaxy S 4 General] simho:
I've read a bunch of threads and understand the concepts and all but have a specific general question.

Questions:

After this tweak will the phone automatically switch bands when one switches from say a Rogers SIM to a T-Mobile SIM and vice-versa? No other setting changes required?

Is the M919 and I337M the same hardware wise and some bands have been disabled by software?
[AT&T Samsung Galaxy S 4 General] D00lie:
You guys who've enabled aws. Any battery life changes with the quicker speeds or signal differences?
[AT&T Samsung Galaxy S 4 General] CanadianKB:
i agree about this completly! But my point is still that the US does not use band 7/2600MHZ but the phone can receive the signal so should it not work in europe? which is why i started a new thread about international coverage which is a different topic, it sounds like your saying AWS is related to 2600MHz???? Im still a little off about AWS all i know is my phone has it, lol. I only thought youd want to enable it to port to say WIND mobile in Ontario which uses only AWS i believe.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
No. Because the frequencies that are listed are the ones that are turned on. And like I said, the reason we were able to enable AWS HSPA+ on the AT&T S4 is because the modem's memory (data/backup) are the same as the T-Mobile model, except for the "flipped switch" to enable AWS HSPA+. The GSM Galaxy S4's in the US are capable of these for LTE (as in turned on): 700/850/1700/1900/2100 MHz. No 800 or 2600 MHz.

It MAY be possible to flash an i337M backup onto an i337/M919 to enable 2600 MHz, but I wouldn't try it. It might work though since the T-Mobile (M919) backup in this thread works on i337M's.

[AT&T Samsung Galaxy S 4 General] Product F(RED):
No, you don't have to perform this mod. AWS HSPA+ (3G) means 1700/2100 MHz (both together). This is only used on some carriers in the US and Canada. If you do this mod, it won't change anything in your case (Germany). The phone should work as it is for you right now on HSPA+.
