thanks

I brougth an att sgs4. Follow this thread to unlock it and works ok. After that just press *#2263# and choose CDMA 1700. As simple as that if this helps someone. (Stock 4.2.2 rom)

I read all the pages on here... It's my understanding that unlocking these extra bands for the speed is only for T-Mobile users? I'm an ATT user and don't plan on changing, so if I did this mod, nothing would be changed?
[AT&T Samsung Galaxy S 4 General] Mocheen:
Anyone know if this works for the I9505 S4???
[AT&T Samsung Galaxy S 4 General] sonny21:
Unlocking these extra bands is for those who want to use T-Mobile/wind /etc sim card with at&t/Rogers/etc s4. If you don't plane on using those carriers aim card, then correct, nothing would be changed.
[AT&T Samsung Galaxy S 4 General] mathieulh:
This mod may allow you to switch between international (I9505) and American bands Qualcomm Variants of the GS4, I guess that's something to test for those who imported phones abroad.
[AT&T Samsung Galaxy S 4 General] simho:
I did this on my i337m yesterday. All appears ok. I was able to detect Wind and Mobilicity on my device. Will be in Portland in a few weeks to test out on T-Mobile.

I do have a question for clarification. This is more to better understand what specifically is being modified to enable AWS.

Others have asked if OTA updates will remove and it's been confirmed it will stick. Someone else noted Odin back to stock and AWS enabling stuck.

So what does this change? Is it part of the modem? So flashing a different modem would change it? I presume flashing ROMs would do nothing as they don't touch the modem.
[AT&T Samsung Galaxy S 4 General] nacos:
Works wonders! Thanks a lot!

Correct me if I'm wrong, please: if I flash another (or the original) modem, these settings will be lost and I'l eventually have to go through the process once again, right?
[AT&T Samsung Galaxy S 4 General] sonny21:
Correct. As long as you don't flash another modem, it will stick.

---------- Post added at 05:57 PM ---------- Previous post was at 05:56 PM ----------

Correct.
[AT&T Samsung Galaxy S 4 General] m00nman:
So if OTA comes with a modem firmware update,then we are screwed until we get to a computer to reflash it. Don't know if this is a good idea, but what if happens if i9505 modem is flashed? Brick?
[AT&T Samsung Galaxy S 4 General] blyndfyre:
Just freeze your OTA firmware updates until you are near a computer.
[AT&T Samsung Galaxy S 4 General] george241312:
Yes

Thank you Op for providing this guide i was about to flash a tmobile modem to get the aws bands this way i dont have to take such a risk

I have a question. If I enable this AWS mod and everything its working fine. For example, If I flash an AOKP ROM I will lose the MOD ?

How i can now if my Telcel (mexican S4 I733m) is already AWS open? There is exist some command or value to confirm?
[AT&T Samsung Galaxy S 4 General] sonny21:
I guess either try a SIM card that is from an AWS carrier or try to search for networks and see if AWS carrier shows up in network search.

My wife has her s4 carrier stock rom telcel and she can find another carriers... in mexico we only have 3 telcel is most bigest... my s4 has canada stock rom and its unlocked and we saw same carriers on networks... so mine its unlocked now and i saw the same she can see... whats the difference then????

Thats why i asked about AWS detection or service menu
[AT&T Samsung Galaxy S 4 General] ma678:
Nice find. It does boost my speed on Wind.

Do you know you can change it under setting/mobile networks/preferred network types?

I almost go to complain Wind's network useless in Vancouver.
[AT&T Samsung Galaxy S 4 General] tnap1979:
Not sure if I'm losing my mind.. Lol

So here is my scenario...

I've been thru a few galaxy s4 handsets over the last year and I've always hated the KNOX bs that Samsung has incorporated..

We'll regardless it killed my ability to free unlock a few devices for friends, and has also hindered me a few times.. Needless to say..

I'm confused as to what I've done to my phone in a good way

I have telus locked and branded galaxy s4 i337m

Again, it is NOT sim unlocked.. It is on 4.3 stock mk6 build.

Has 3.4.0 kernel, and was rooted with SafeRoot

Knox was disabled and removed, I installed root browser, and busy box free

I then installed phoneutil.apk, removed some samsung bloat,

Then rebooted, opened dialer, dialled *#0808#, it came up with a different menu then I expected

I choose an option #2 "something & something hcis" or something like that

Rebooted again, dialled same code above, and for some odd reason it sent me to the DIAG Mode

So I followed the procedure to enable aws from step 5 of the OP

And EVERYTHING succeeded, no failure at 5% like others! no blocked access

Nothing.. Everything worked without error, now I'm waiting on my sim unlock code to be able to test out aws as I'm a wind subscriber

So I will post here with any further updates and news once I get my code
[AT&T Samsung Galaxy S 4 General] ma678:
Interesting. You're supposed to unlock your phone prior to this mod.
[AT&T Samsung Galaxy S 4 General] toysareforboys:
When I changed it under the preferred network types it never "sticks". When I get a poor signal and it goes back to "3G" it never tries to go back to 4G again :( When I set the setting in that dial menu it actively always tries to be on 4G. Not sure if that setting will have an effect on battery life or not, guess I'll find out soon :)

-Jamie M.
[AT&T Samsung Galaxy S 4 General] ma678:
I only see H, H+, or no signal. Aren't we on Wind as well?
[AT&T Samsung Galaxy S 4 General] tnap1979:
Well it IS true, worked for me without unlock first

so, i had a late night and trip to hospital earlier today..

not fun, but all is ok..

so here is a few pics i took of my STILL sim locked s4 with the wind HOME network clearly available when i have a telus sim inserted to scan networks

so it did indeed seem to work without unlocking first

SGH-i337M NE1

I have a Canadian S4 (i337M) with the NE1 Baseband on it, and I also have the problem of not being able to either back up my phone (Disk Error while writing to file.) or write the new qcn file to it (Received an invalid command from the phone)

I have tried switching to another baseband but none of them will successfully write in Odin or Heimdall. I tried MF3, MDJ, and MG1, but all of them fail writing. It seems likely that our bootloader is no longer as unlocked as it used to be...

Has anybody gotten this to work with NE1, or figured out how to put a different baseband on NE1?

I WAS able to run CF-Auto-Root on it, at least...
[AT&T Samsung Galaxy S 4 General] toysareforboys:
What version of odin are you using? I had to use 3.07, any newer ones were just giving me "invalid command" errors.

[AT&T Samsung Galaxy S 4 General] ma678:
I updated my Fido S4 from NE1 to NE3 with Odin 3.09. No issue.
[AT&T Samsung Galaxy S 4 General] acwest:
I considered that, but if my current radio doesn't let me fix the AWS, it seems unlikely that a more recent one will be better. Did you apply the AWS patch while your phone was at NE1?

---------- Post added at 09:56 AM ---------- Previous post was at 09:51 AM ----------

I have tried both 3.09 and 3.07. I am pretty sure I would be able to upgrade my radio to NE2 or NE3, but that is unlikely to improve my chances of applying the AWS patch. On the other hand it is possible that one of those already works with AWS.
[AT&T Samsung Galaxy S 4 General] maisterbackel:
I have an issue related to this. My band is NE1 and qpst wrote the qcn file no problem, however it looks like there is no change in what carriers I can see. I'm using WIND and I can still only see WIND AWAY all the time.
[AT&T Samsung Galaxy S 4 General] ma678:
Are you sure you have wind coverage there? I see wind away all the times because there is no coverage around my office at all.
[AT&T Samsung Galaxy S 4 General] emin911:
Hey folks

I just got my S4 and it was locked to Telus. I just got it unlocked, So I can use it with wind. I have couple questions:

1) I am on android 4.2.2 right now, Should I upgrade my version before I do the AWS mod?

2) If I do the AWS mod on 4.2.2, will I be able to update to 4.4 and later versions?

3) will my signal suffer from doing this mod compared to buying a AWS enabled S4 directly from wind?

Thank you for you help :)
[AT&T Samsung Galaxy S 4 General] ma678:
Yes for the first two. Not sure there is any difference for question 3. I guess not.
[AT&T Samsung Galaxy S 4 General] emin911:
So I should upgrade to android 4.4.4 before I do the AWS mod? would I be able to do the same steps as the video since stuff have changed?

Thanks for your help
[AT&T Samsung Galaxy S 4 General] maisterbackel:
Yeah it worked fine once before, I was on CM, then for whatever reason it broke, so I reflashed the stock rooted 4.4.2 NE1 for my model, did the AWS unlock but it still can't see WIND :( I'm sure it has coverage where I work and live. Does it make any difference if I do the AWS thing with my sim card in the phone? I kept it in for the entire process.
[AT&T Samsung Galaxy S 4 General] ma678:
Better apply mod before upgrading to 4.4.4. Most of time AWS will retain.
[AT&T Samsung Galaxy S 4 General] @moe:
Not sure if anyone noticed.. but if you unlock the phone and hit *#2263# you will have the option to select any band you want.. i never did the qpst option and i get lte and H+ on tmobile .. running NB1

i could be wrong tho
[AT&T Samsung Galaxy S 4 General] acwest:
Well, I was able to write an NC1 radio to my phone (I extracted the one from the Bell stock firmware tar.md5 file) but the AWS patch still isn't working in qpst. I am going to try working back through the Bell modem firmwares to see if I can find one that works...

SPC Code

I have a feeling that all of this messing about with radio flashes is not going to help me, the issue appears to be that for some reason this phone has a different SPC that the default 000000. I don't suppose anybody knows how to figure out what it is?

[AT&T Samsung Galaxy S 4 General] Product F(RED):
i337M should support AWS LTE (what T-Mobile uses). The i337M is used in Canada and all Canadian carriers use the same frequency as T-Mobile for LTE.

[AT&T Samsung Galaxy S 4 General] ma678:
From my experience, it's no need to backup the mod because it's a flash and forget process. After I flashed the mod, I have upgraded stock rom over OTA or Kies many times. I have also rooted my phone and installed a few custom roms. AWS remains.

Can you post your settings? I have never sent a successful MMS with this phone. I had no problem on Galaxy Nexus so I don't think it is the network.
[AT&T Samsung Galaxy S 4 General] Solace50:
in all honestly someone should lock this thread and re-create this with a much more informative OP, you currently have like 50 people posting about aws sticking post flashes and upgrades and other questions which are answered vaguely and repeatedly in certain cases.

the modem is generally not touched unless you use odin to push the firmware through or its an OTA from my experience. even forcefully upgrading the modem is finicky at times due to samsung which mobile odin has proven requiring stock roms/recovery etc...

[AT&T Samsung Galaxy S 4 General] Product F(RED):
Your modem is NC1, not MF3, so the mod isn't going to work. Is your phone rooted? I have a T-Mobile Note 3 now, so I haven't kept up with the S4. You either need SafeStrap (or whatever is the most up-to-date method), or you need to have Loki (which I doubt you have).
[AT&T Samsung Galaxy S 4 General] dr_pepper:
So - followed the guide and everything seemed to go ok, however when I go to network operators I still only see Telus, Rogers, Bell. No AWS/Wind. Do I need an actual Wind SIM
[AT&T Samsung Galaxy S 4 General] dr_pepper:
Ah - so looks like I need to downgrade my modem (currently NC1)? If that's the case can't I just use clockworkmod to install the old modem or do I actually need to go the other route of busybox.

My phone is currently unlocked so here is my overall question. At the end of the day I'd want to be off of touchwiz and onto cyanogenmod 11 and would want my phone to be able to access AWS as well as other bands. Currently I'm unlocked, on touchwiz, with NC1, rooted via towelroot, with Rom manager and clockworkmod recovery 6.0.4.7.

Is it possible to downgrade my modem via clockwork to previous version to unlock aws.........then install cyanogen and still retain access to aws? Will cyanogen 11 upgrade my modem and does that kill AWS. Or once aws is enabled, can i upgrade the modem and the aws enablement will stick?
[AT&T Samsung Galaxy S 4 General] sonny21:
I was on ne1 and successfully did the mod. You don't need a different sim card to see wind/aws.

Oh you have an i337M. I thought i337. The MF3 modem is for the AT&T i337, so don't flash it. Someone above mentioned it works for the i337M on NE1, so try that. You may have to flash the modem through ODIN. I remember reading that for some reason the i337M won't take modems through custom recovery.
