You will hard brick your phone.

Sent From My Galaxy S4 SAMSUNG-SGH-I337 Running On New Deadly Venom v3.0.1 KitKat 4.4.2
[AT&T Samsung Galaxy S 4 General] Product F(RED):
I've done that on the Note 2, but with the T889 (T-Mobile Note 2) modem on the i317 (AT&T Note 2). The phone would boot fine for a minute. Then it would reboot after a minute after everything loaded. My IMEI would say "Unknown" until I flashed the correct modem back. I also had no service (circle with line). When I flashed an AT&T modem back everything was back to normal. But that's really a best-case scenario and it could be much worse on another model.
[AT&T Samsung Galaxy S 4 General] att85:
Okay, but would I break the "hardware". Or could I flash always the All-in-One MK2 Full Odin tar ?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
1) It won't work. 100%. The modem partitions are different across models.

2) Possibly. I don't know what the effect would be on the S4. My experience cross-flashing modems with the Note 2 was a failure.

3) It wouldn't increase your signal or anything dramatic even if it did work.

It may be irrelevant at this point--but the att mdb s4 only came out mid-late April and was mdl when I got my two black 32gb ones. That's why I waited till first week in May to buy them. There wasn't an att S4 in March for att. afaik. So not sure what phone it would have been on--other than test phones by att/samsung employees--so, kinda how you look at it :confused:
[AT&T Samsung Galaxy S 4 General] Dillsnik:
Hello, I am on ATT MDL baseband and i know it says clearly in the first post updating baseband and modem will not lock bootloader, but i thought people who upgraded past MDL were now on locked bootloader. Would possibly like to update my radio since i am having some signal drop issues, but i do NOT want to risk my updating options. Thanks so much!
[AT&T Samsung Galaxy S 4 General] :
You won't change BL by flashing a radio on your phone. I have flashed most of them thru recovery. On nb1 now. Not sure if any did much better than the other. YMMV :)
[AT&T Samsung Galaxy S 4 General] dirt:
Even on MDL your bootloader is still locked. The loki workaround is just that, a workaround or patch. The modem is how your device communicates with the towers/service. Just like rugmankc, I haven't noticed a huge difference in any of them. Keep in mind that some modems may work better in some areas and worse in others. I have also flashed all these through recovery.

Hi,

I'm having some trouble getting wifi to work. A few days ago on my phone (Rooted, and stock MK2 at the time), wifi started acting up (just after installing a sonos controller and playing around with sonosnet, which I thought was the problem, but it may have been coincidence, given what I've done since) - it had been fine, and suddenly it started disconnecting intermittently, saying that the connection was too low quality. when it tried to reconnect, it would say Authentication Failed. It still does intermittently connect, but quickly fails with some error (the quality one above, "you need to re-login to your network" - as though it were a public AP). I've done the following to attempt to resolve this issue:

Flashed the NB1 stock rom, via method one here, including the FMLD bootloader fix. This gave me the NB1 baseband.

I just tried flashing the FMLD modem from the OP.

I tried the wifi fixer app at the play store, and found that it just more aggressively retries and keeps the wakelock active (which does result in somewhat, although not a lot, more time spent connected to wifi, but at the cost of a completely dead battery very quickly)

It's still having the same problem. any ideas?

[AT&T Samsung Galaxy S 4 General] :
Don't know about i337 in Europe and the frequency bands. But, you can only install i337 radios. Doubt any of them would make a difference. afaik

[AT&T Samsung Galaxy S 4 General] Product F(RED):
There is no modem "built for this". There's another thread of modems. The OP of the other thread doesn't know what he's talking about and listed a "MDL w/AWS ENABLED" as a modem. The modem itself doesn't hold the mod. It's a separate process to enable it:

To make it clear "The OP" above comment posted about is NOT the OP of this thread. I do NOT have it listed as a AWS modem.

The modems that allow for the "AWS MOD" can be done on the MF3 modem (and I think the older MDL or MDB modems as well. But I haven't tried it yet so not positive. So check out the thread listed in the comment above me for HOW TO perform the AWS MOD.

Yes, I meant OP of the other thread. I'll edit the post to make that clearer. And yes, MF3 is the last i337 modem that can be used in conjunction with the AWS mod. I've tested newer and it fails to flash at 5%. If you have an i337M Canadian variant, you can still use it with the newest modems thing (I believe NC1).

You well need safe strap to flash a modem or ROM. Some have reported better service with newer modems.

I don't have to do safe strap so in not an expert on that. However, a modem will not ruin anything. The safe strap stuff is a little more involved and the brick thing may arise from that.

New to modem flashing

Hello,

I have flashed quite a few roms since getting my AT&T GS4, but have never changed a modem. I am still on MD1. I have tried GE 4.4.2 and now 4.4.3, and have found that regardless of kernel or installed apps, I get a ton of kernel wakelocks, specifically from msm_hsic_host, PowerManagerService.Wakelocks, wlan_wd_wake, main, PowerManagerService.Display, and other wlan wakelocks. According to wakelock detector, my phone is awake ~45% of the time.

I tried to do some research into what could be causing it, and it appears that an incorrect modem might be to blame. I thought I would start with the more recent KK modems and see if they fix anything.

So I have two questions:

1) Does it seem plausible that changing the modem could improve all these wakelocks?

2) I thought that one needed Odin or Mobile Odin to flash modems, but it seems from this thread that the modems can be flashed from recovery in the same way that one can flash ROMs or kernels. Is that true? Or have I missed something?

Thank you in advance for your help.

Regards,

Jon
[AT&T Samsung Galaxy S 4 General] RockRatt:
1) I could not say as I do not get any wakelocks, but I am on ShoStock-i V6.1

2) YES, our i337 from ATT can flash from recovery just as you would flash a ROM.

The other variant i337m has to use Odin to flash modems. Not sure why though.

[AT&T Samsung Galaxy S 4 General] jon6fingrs:
Awesome, thanks! Flashing the modem was pretty easy, but no change in the wakelocks yet. I'll give things a day or so to settle and see what happens. Pretty annoying considering how much I like my setup on GE 4.4.3.

Have you thought about going back to stock, formatting internal and rerooting--:)

That is for the i337m variant. The i337m variant has to use modems that are tar'd up and flash with Odin from my understanding.

I saw that then got sidetracked. You can't put a tmobile modem on att phone. Hope no one tries--
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Tried it with my Note 2 and S4 (when I had them; I have a T-Mobile Note 3 now). You will lose your IMEI and the phone will bootloop and not get any service until you flash back an AT&T modem. Not worth the danger because you may permanently lose your IMEI. The modem partitions are different. There's a way to enable AWS HSPA+ for T-Mobile if that's what you're trying to do. Only thing is you have to use MF3 modem (for i337, though the mod also works for the i337M).

If ANYONE with the I337 ATT 16GB S4 model can pull the pit file for me I would like to place it into the OP first post. You can use Terminal Emulator from the phone and follow these easy directions. If not I will pull it tomorrow from my wife's 16GB S4. Thanks ahead of time.

DIRECTIONS:

Use this code for use in Terminal Emulator to pull the pit file:

su (enter)

dd if=/dev/block/mmcblk0 of=/sdcard/SGH-I337-16GB.pit bs=8 count=580 skip=2176 (enter)

I suggest opening up Terminal Emulator app and hit su, then approve root access, hit the "x" button and close Terminal Emulator. Reopen Terminal Emulator and the type above directions.

Are you SURE CWM is installed? I don't think it is possible if you came from NC1. when you go to recovery does it say CWM RECOVERY or 3E recovery?

My guess is CWM did not actually flash (hopefully not). Because I believe if it is flashed on anything OTHER THAN MDB or MDL you can lose stock recovery.

Once you have Safestrap you can flash these modems. Look at the info in the OP for Safestrap users (I have never used Safestrap so know very little of it. Other Safestrap users have flashed the modems).
