Lol thanks for coming out
[AT&T Samsung Galaxy S 4 Android Development] force70:
What you meant to say was i337 is not supported but i337m is supported right?

That is correct and I am sorry about the confusion from my part, what I mean was the I337 is not supported, I am pretty sure I337M is supported

No worries, if you would have read a bit you would have figured that out ... Its on chainfires mobile Odin op. If you're on 1337 and your trying to use the mf3 modem then flash the zip through recovery
[AT&T Samsung Galaxy S 4 Android Development] mgfjd:
The Galaxy S4 from Telstra is using the snapdragon processor any chance the modem would work for our phones? I came from using the ATT HTC One X and the Telstra modem was far superior than the ATT one.

The developers ditched anything related to ATT and use Telstra as rom bases. The LTE was flawless.

Thanks.

I have the stock recovery would that work, if yes then I have to rename the file to update.zip,
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
I would recommend flashing a custom recovery and then flashing the zip in there then if you want to go back to stock recovery you can. Haven't try flashing through stock so I can't recommend that way. If you do let me know and I can add that to the op
[AT&T Samsung Galaxy S 4 Android Development] nkhater:
As you know MF3 has a locked Bootloader, that means I am stuck with the stock recovery and I can't flash any other recovery, if your MF3 isn't signed, flashing this using stock recovery would be near to impossible
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
You can root and install recovery on mf3

►I have already received the OTA update / My device shipped with MF3:

In this scenario, visit [MENTION=4399896]jortex[/MENTION]'s recent root guide here in order to achieve root access. Although there is now a root method for the MF3 firmware, please understand there is no custom recovery, no option to revert to older firmware and no current MF3 Odin-flashable firmware image. Proceed at your own risk.
[AT&T Samsung Galaxy S 4 Android Development] josemald:
I went through a few pages of the thread. Just to confirm, the AT&T model can flash the MF3 modem using the zip file from the first post using recovery (I used TWRP). Just to be sure, I cleared cache and dalvik before and after flashing, and fixed permissions after flashing, as suggested by some post. After flashing, the baseband version changed to MF3 in Settings. I'm still able to get to the USB settings menu (*#0808# in the dialer) and hidden service menu (*# 0011#) required to activate AWS and SIM unlock, but I don´t have access to a TMobile SIM card to check if I retained both features after flashing. But if I lost them, having access to the menus means I can get them back, I would think.

By the way, I'm using Mint Jelly ROM, which is a 4.2.2 touchwiz, in case it matters. The kernel says MST 2013 and build number says MJ3.
[AT&T Samsung Galaxy S 4 Android Development] nkhater:
The ROM does matter, if you are on MF3 OTA baseband, that means you have a locked bootloader, therefore you are stuck, if you have root and try to flash a custom recovery for example TWRP, be aware, you will be bricked,

MF3 Radio from this post

OK, I am confused (just a bit). I am on I337UCUAMDL baseband and I have NEVER used a stock OTA update. I am running task650's AOKP build from 7/28/2013 with his stock kernel.

If I flash the MF3 radio for AT&T will I get a locked bootloader, or is that just for OTA and factory MF3 (i.e., if I flash this MF3 radio, will I be able to continue updating my ROM using whatever ROM I choose? I was not able to make sense of this from this thread.

I have been using MVLUAMG1 for a while now and upgraded to foxhound 1.5 form foxhound 1.4

After installing the rom im trying to update the modem from MVLUAMDJ to MVLUAMG1. I tried it via mobile Odin which was neevr an issue before and everything seemed to go ok but baseband still shows MVLUAMDJ

I tried via odin and get auth fail at the last part (writing)

any ideas?

Hey what device are you using? When you were using mg1 did you have mdj modem installed... How did you obtain mg1? Is it pure stock? Did you obtain it from ota?
[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
I'm using a rogers i337m. Been using foxhound for a few months and got mg1 via this thread and been flashing it via mobile odin ever since it was released.

From the looks of it the issue started when foxhound changed the rom base to XXUBMGA. Since then mdj is installed by default and I can't change it as mentioned.

I clean installed the rom and tested with twrp and phil recovery and same thing. Mobile odin looks like it works but info in settings remains the same
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
I had the same issue before, all I did was go back to a Canadian based firmware and flashed again, problem solved.. It may have something to with the build prop/international firmware. If I'm not mistaken foxhound changes your device to read as a i9505 so this may what causes it not to flash, let me know if this doesn't work out for you
[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
Is there any way to change just that info but keep the firmware? Maybe a build prop editor
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Yeah for sure but not sure if it will solve you're problem, but if that's all you have to do its allot less work

Need help

Hello friends!

Need some help here.

I live in mexico and my carrier is Telcel. I bought the AT&T S4 I337 Unlocked; the Telcel model is I337m.

The phone is rooted and running wanamlite and it works fairly well but I have some connection problems.

At first it has to reconnect 3 or 4 times to have a stable conection, and works well for whatsapp, facebook, gmail, etc.

But it is impossible to download a big file because it looses the conection.

I have tryed different ROMs, different modems, and different kernels, but the problem persist.

If I flash Telcel modem (I337MUMUAMDL) it doesn't recognize the simcard as if it has none installed; I'm guessing this is because I'm flashing a I337m modem to a i337 phone, but isn't supposed to be the same hardware?

Is there any possible way to make it work using the i337m modem?

What other options do I have?

Thank you in advance for all your comments.

Note: BTW it is not the signal because I337m have not this issues

[AT&T Samsung Galaxy S 4 Android Development] jpdediego:
Sorry for the confusion.

I have the at&t i337.

Tried flashing the radio from my carriers model that is i337m but didn't work (didn't recognize the sim card with that radio).

At this moment I think I fixed but it is only a couple of hours testing but it is much more stable.

What I did was flashing the MF3 modem and then unlock all bands (aws) using the tutorial around here.

So far so good...

I'll be telling if this was my definitive fix to my particular problem.

Good work, that's what I was gonna tell you to do, that should fix things permanently for you... Stick to your model, even though your on telcel the mf3 is unlocked so you will get the band's anyways and mf3 is meant for the 1337 :) best of luck
[AT&T Samsung Galaxy S 4 Android Development] jpdediego:
Yeah but one question remains.

Isn't supposed that i337 and i337m have the same hardware?

Why i337m modem is not working with i337? Is it because of the locked bootloader?

Until now it is much more stable with MF3 but I'm loosing connection when downloading large files =(

Not that I do that a lot but shouldn't do that.

I'm Telcel too, let me tell you that connections issue is not modem problem because I have Telcel one and 4G has the same problem, but I'm in att ROM Omega 9.0 and maybe is that.

maybe Telcel ROM has some settings that make stable connection or maybe is a Telcel compatibility problem.

I tried repackaging. Clearly I did something wrong. If you make a test zip, I'll test it out.
[AT&T Samsung Galaxy S 4 Android Development] FireRaider:
I am not running stock rom either and I have run the program twice and it has worked both times. Remember, its a program that loads a different NV file or something, not code that you enter to unlock anything

I had to unlock my modem the second time after I flashed a TMO rom which apparently had the modem in it or something because it turned off the opened up frequencies and all I could get was EDGE with my TMO sim card, they didn't work with the TMO sim even after I did a nandroid restore back to my ATT rom. So I used the procedure in the AWS thread and got them back again. I still have the TMO rom saved as a nandroid backup so I could test out the modified modem zip rather quickly if it gets posted here.

Assuming of course that I actually get time to check the forum while at work. :D

If someone gets this to work it will be one of the more useful things posted here. IMHO

If my understanding is correct an unlocked modem pulls from LTE (not non-LTE 4g, and not 3g or edge) signals from all available sources regardless of which network it is registered to...I think I remember reading that somewhere when I was researching this last week...

I now see based on prior comments Odin and CWM from PC do not play nice on canadian phones, and I cannot get back into android to use mobile odin. Help?

I did actually get it booting by installing a stock custom rom from TWRP. When I booted wifi won't enable and detect however. I then flashed the appropriate Telus kernel for my carrier but still no wifi. I suppose the upside is my baseband is MG1.

i9500 S4

I own a factory unlocked GT i9500 that I'm using on AT&T network with WanamLite 1.8 ROM. Everything works OK except I don't get LTE which is not a major issue for me. I mostly use Wi-Fi and it's rock solid. I'm going to be switching to ConsumerCellular at about 1/3 the cost in a month and they resell AT&T network here in Chicago with their own SIMs. Been looking for modems, My baseband is MDK and WanamLite is MG1 base. Anyone know how these radios would flash with CWM to an international i9500 running on the AT&T network?
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
That's a good question... I feel that because your own the att network you should be fine to flash any of the att radios but the kicker is that its an international phone... I dont think it would be an issue.. you could always flash back if it doesnt work
[AT&T Samsung Galaxy S 4 Android Development] Product F(RED):
I'm confused. I know how the mod works because I came from an AT&T Note 2 (which I did the mod on, which works the same exact way), and currently a T-Mobile Note 2 (which obviously doesn't need the mod). I'm currently on an MDB modem.

I'm running a T-Mobile ROM (Wicked ROM 5) because I want Wifi Calling.

2 Questions:

1) I'm not accustomed to having a device with a locked bootloader, although I have a recovery that auto-Loki's everything so it's not a big deal. But if I flash one of the MDL modems from the OP, can I later go back to MDB? Or will a QFuse blow and I can't downgrade?

2) I noticed one of the MDL modems says "AWS Unlocked" (or similar) next to it. To my understanding, you have to enable AWS using QPST and an NV Backup from a T-Mobile device. I even checked the AWS and non-AWS MDL modems attached on the first page using a hex editor, and they came up with 0 differences. If I flash the AWS enabled MDL file, will I have AWS? Because it'd be great to not have to be near a computer if I have to ever reflash my modem (to enable AWS).
