Since I am incorrect, where does the discrepancy lay? It doesn't allow me to even go beyond the point where it tells me "device model not detected, you can create a dump file if you want, yadda yadda yadda." Haven't been able to use it beyond that since I first got the S-4. Any advice would be immensely appreciated![/QUOTE]

Mobile Odin installed on my SGH-I337M, no help as to why it does not install on yours, just confirming it does install.
[AT&T Samsung Galaxy S 4 Android Development] AlEjAnDrO812:
Try unistall and re install..

Does your build prop read SGH-I337H, it didn't flash for me on custom Rom cause custom Rom changed build prop version.I had to edit build prop back to original.
[AT&T Samsung Galaxy S 4 Android Development] force70:
I flashed the mg1 modem.bin file on mobile odin and it works.wifi is fine..I'm on rogers btw.

Could not get.the tar file to work.
[AT&T Samsung Galaxy S 4 Android Development] ksmkk3:

Looks like SGH-I337M is supported, but SGH-I337 is not yet. I supposed you could just edit your build.prop, but who knows what that would screw up with Odin.
[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
How did you do it? I tried via mobile odin and when I select modem and point it towards the unzip tar where the modem.bin file is it only sees the NON HLOS bin file
[AT&T Samsung Galaxy S 4 Android Development] ragz:
Success,it finally changed modem version.

-I downloaded MG1 file

-extracted bin

-opened mobile Odin

-used modem 2 slot to find extracted bin file

-Hit the flash firmware button

-system booted to download

-waited for 5 minutes, seemed to be going no where so I long pressed power button to reboot.

-phone rebooted and said mobile Oden is installing md1 files

-phone boots up, checked phone version and success.

Thanks 2Tone5 for the files.
[AT&T Samsung Galaxy S 4 Android Development] force70:
In.my case.did.the.same thing i.usually do, hit open file..click on.the modem file and.hit flash

---------- Post added at 10:05 AM ---------- Previous post was at 10:03 AM ----------

Once you see the green android hold the power button.for a bit and it will boot into odon flash then reboot. Its a bit odd i know but thats how it goes

MF3 modem, wifi wake locks

Just a comment and question on the MF3 modem.

I was on the mdl baseband, MF3 modem and Cleanrom 1.5 (debloated MF3 update)

modem seemed to work fine for a few days, except I seemed to drop LTE more frequently.

Noticed excessive battery drain, when I looked at better battery stats, wifi was keeping the device awake 100% of the time.

Device never went into deep sleep, if I disabled WiFi the battery drain issue disappeared, so I'm 100% sure of my conclusion.

Flashed back to MDL and the problem disappeared.

Just something people who are using MF3 may want to look out for, also has anyone else experienced this?
[AT&T Samsung Galaxy S 4 Android Development] Gordietm:
Flashable zip would be great. I don't have mobile Odin, but tried flashing the tar file and then the bin file with Odin desktop and fails every time.
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Zips are apparently not working on the new firmware ... mobile odin is free. I highly recommend it. .. otherwise you can try using adbshell .. instructions in the op...
[AT&T Samsung Galaxy S 4 Android Development] Gordietm:
Installed mobile Odin, flashed bin file and everything worked like a charm, thanks :)
[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
had same issue but worked after a bit.

make sure to use odin 3.7 and also select phone and put modem.bin in there
[AT&T Samsung Galaxy S 4 Android Development] Octane70:
Also make sure reboot is unchecked
[AT&T Samsung Galaxy S 4 Android Development] force70:
For all.my can bros the update to the MG1baseband is well worth it.my signal is better and LTE speeds are def up..i hit over 100mbps down for the first time ever.
[AT&T Samsung Galaxy S 4 Android Development] fmark:
Does it enable AWS band ? Thanks!
[AT&T Samsung Galaxy S 4 Android Development] Jashyk:
I lost the LTE I had before flashing the MG1 modem, although it was a pretty weak 2 bar signal. I'll give LTE it a shot tomorrow though when I go back downtown where the signal is stronger, I think it's just flakey in this dang city.
[AT&T Samsung Galaxy S 4 Android Development] tvd0405:
Would MG1 works with I337?
[AT&T Samsung Galaxy S 4 Android Development] Jashyk:
OK, this is weird, but has probably been covered.

I flashed MG1 and lost LTE, which I had 5 minutes before with MDJ.

So I used the MDJ.zip from the OP and flashed it in CWM, and boom I have three bars of LTE again. Except in my About menu it says I still have MG1. Is that a cosmetic thing, or? I don't really know what modem I'm running now, but I've got LTE again, so I'm not touching it. :)

For anyone running CM10.1, you might want to stick with MDJ for now(assuming that's what modem I'm running now), LTE works much better.
[AT&T Samsung Galaxy S 4 Android Development] Febby:
In my testing no modem worked for the i337 if it wasnt meant for it. Try to odin it if youre curious. Worse that happens is you reflash an i337 modem. :p
[AT&T Samsung Galaxy S 4 Android Development] Jashyk:
And thank you very much for the guys who posted the newest modem dump. I'm new at this, but we always appreciate you doing that!
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:

[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
I wouldn't do it if it wasn't easy lol
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
If the baseband reads mg1 then your still on mg1. .. maybe the phone just needed a reboot
[AT&T Samsung Galaxy S 4 Android Development] agent69:
I followed the same procedure with no luck at all. Do I need to be on a stock firmware to install the modem?
[AT&T Samsung Galaxy S 4 Android Development] force70:
Not at all bro, firmware shouldnt matter.
[AT&T Samsung Galaxy S 4 Android Development] fmark:
Thank you. So I went ahead and flashed the modem in Mobile Odin. Everything seems to work as before.

However when searching for Network, it still shows Fido, Telus and Bell. I expected to see Mobilicity as well (it is available in my area).

Am I missing something ? By the way, does this Modem file also make the phone SIM-unlocked ? Thank you !
[AT&T Samsung Galaxy S 4 Android Development] agent69:
Very strange... I tried with Mobile Odin and Odin with no luck at all.

[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
For people using new modem have you noticed any difference in terms of battery?

My signal seems better but I lost 4% more battery than with previous modem on rogers

Normally overnight I go from 100 to 97 or 96 but today I woke up and had 93%

My rom is same as before using foxhound
[AT&T Samsung Galaxy S 4 Android Development] force70:
Ill give it a few charge cycles to make an observation on battery.that being said i used my phone heavily yesterday and still made it home with 30%.
[AT&T Samsung Galaxy S 4 Android Development] simho:
I'm so confused. I've looked in the OP for MG1 with AWS enabled and only see MDJ for Canada. Also, are all the zips and tars AWS enabled, with the exception of that explicitly noted as W/O AWS? I'm assuming no because it is not explicitly noted.

I'm on MDJ with AWS enabled via the qcn file. I'm on Rogers so would like to update if it's worth it as you say. :confused:
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Ill update the op when I get home.. its my birthday so im out right now :)
[AT&T Samsung Galaxy S 4 Android Development] pinoymutt:
I saw a few debates about Mobile Odin and compatibility.

The bottom line is that Mobile Odin supports the non-bootloader locked variants of the North American SGS4's like all of the Canadian versions (to my knowledge) and the US versions such as TMo and Sprint.

It does NOT support the bootloader locked variants (ATT & Verizon) and the LOKI workaround makes no difference. The dev said if/when the bootloader is fully and truly unlocked is when Mobile Odin may be considered for the variants it doesn't work on.

So hopefully that answers why some people are having no issues with Mobile Odin working to flash their modems and others get "device not recognized."

Now back to regularly scheduled programming... (anyone successfully made a MF3 with unlocked AWS yet? :D)

[AT&T Samsung Galaxy S 4 Android Development] fidorulz:
Using ausdim google edition kernel v11 on foxhound 1.3 on my rogers galaxy 4

Was using this kernel and rom with previous canadian radio and would lose 3% of my battery overnight between 11pm to 6am

Now with new radio my reception and speeds are a bit better but I lose 7% overnight under the exact same conditions

No new app or widgets other then the radio nothing was changed

I use green power premium to save battery and have it setup to turn off wifi and data overnight

When I get home I charge my phone to 100% till 11pm and wake up at 6am so my routine is always the same as well as the phones connection or usage

Part of my wanting to do this :)
[AT&T Samsung Galaxy S 4 Android Development] 2Tone5:
Doesn't matter. .. If you haven't flashed a modem yet then you'll still have the stock modem
[AT&T Samsung Galaxy S 4 Android Development] Sc4ryB3ar:
OK I have the terminal command to extract and copy to SD card, what block am I looking for and does it change by variant?
[AT&T Samsung Galaxy S 4 Android Development] AlEjAnDrO812:

From my understanding from the thread you have to be on a stock ROM to run the AWS mod. Am I wrong on this?
[AT&T Samsung Galaxy S 4 Android Development] AlEjAnDrO812:
I made this tutorial for people than whant to help

You have to have adb and have knowledge on how to uset it

Extracting a modem TUT

First extract the modem to your internal memory

adb shell su -c "dd if=/dev/block/mmcblk0p2 of=/sdcard/modem.bin bs=4096"

Second the NON-HLOS.bin

adb shell su -c "dd if=/dev/block/mmcblk0p19 of=/sdcard/NON-HLOS.bin bs=4096"

Third pull the modem from the internal memory

adb pull /sdcard/modem.bin

Four pull the NON-HLOS.bin

adb pull /sdcard/NON-HLOS.bin

In this case we need only the modem :)

[AT&T Samsung Galaxy S 4 Android Development] Sc4ryB3ar:
In this the pull command just puts it on the PC, right?

So, if you use these two commands in terminal emulator then they're on your ad card and you can upload them from there without the mess of adb and a PC. Or am I totally wrong on this?

su -c "dd if=/dev/block/mmcblk0p2 of=/sdcard/modem.bin bs=4096"

su -c "dd if=/dev/block/mmcblk0p19 of=/sdcard/NON-HLOS.bin bs=4096"

And in all reality if we just need the modem all we need to do is.....

1. Open terminal emulator.

2. Run this line of code: su -c "dd if=/dev/block/mmcblk0p2 of=/sdcard/modem.bin bs=4096"

3. Upload somewhere (and provide link if it's not uploaded here) so we can download.

Does that work as needed?

[AT&T Samsung Galaxy S 4 Android Development] romracer:
Right, as I stated in my post, as far as I've ever known, the AWS and SIM unlocks are stored in NVRAM. Not in the modem. Confirming the modem partitions are identical - mine coming from a phone that is SIM/AWS unlocked - only goes to verify this further.

At this point, its been confirmed the MF3 modem is AWS unlockable. You just need to follow the AWS guide making sure to use the new short code (*#0808#) to get into the Qualcomm USB settings.
