So for a MDL GS4 running KitKat,

(GPE or TW based ROM) flashing the NB1 modem is advised? Any pros and cons as I honestly have not seen any problems that I am aware of.
[AT&T Samsung Galaxy S 4 General] beast3300:
Some modems work better than others, better/worse signal performance, better/worse battery, better/worse call quality are usually things will notice. You can change to any and all modems whenever you like.

I'm on Tw 4.4.2 with the NB1 modem currently. So far so good. HTH
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Only downside is you'll lose your AWS mod if you're using it (flashing any modem undoes the mod), and so far MF3 is the newest modem that it works with. This only matters if you're using your AT&T S4 on T-Mobile.
[AT&T Samsung Galaxy S 4 General] stl-soldier:
Thanks for this latest modem guys. This is the best one for me so far. I picked up an average of 25% more speed over WiFi (31Mb to 38Mb down from same server and location in my house). WiFi status shows a 433Mb connection to my AC-only network. Seems like they tweaked something to make 802.11ac work better. LTE speeds remained the same, and no issues with GPS. Quick and accurate lock indoors.

Thanks Jeboo and Rock!
[AT&T Samsung Galaxy S 4 General] gravedigger76:
Is WiFi really affected by the modem? Isn't it only cellular data that's controlled by the modem?
[AT&T Samsung Galaxy S 4 General] stl-soldier:
I was assuming so. If not, I can't explain why my WiFi works so much better after the modem change. I ran all tests in about 5 minutes total, and didn't move at all. I'll try downgrading to see if WiFi gets worse.
[AT&T Samsung Galaxy S 4 General] :
I think within the modem is hardware/radios for cellular and wifi. "I think" ;)
[AT&T Samsung Galaxy S 4 General] stl-soldier:
After reverting, testing 3 times, upgrading, and testing 3 more times, it is still getting better results with the new modem. So many variables though, it could be coincidence. Either way, nothing is worse, and all is well, so I consider it a success.

Flash over i9505?

I have an i9505 bought in France, but I am here in USA and I don't get AT&T LTE cause of an incompatible modem. Also, for some reason, which I am guessing the modem is to blame, my battery life is terrible. I have tried different ROMs, kernels, tweaks, modems, everything, but in vain.

So how can I safely flash these modems on my i9505 and get compatibility with AT&T LTE but also be able to use the phone on Vodafone when I get back to India?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
You can't flash a different model's modem onto your own. AT&T uses 700 MHz. The i9505 only does 800/1800/2600 MHz. Sorry, there's no way around it buddy.
[AT&T Samsung Galaxy S 4 General] :
I am on 4.3 rooted. I want to flash the NB1 modem to see if I can gain better signal in my area

What exactly are the steps to flashing the modem? I have to install safe strap first correct?
[AT&T Samsung Galaxy S 4 General] HiDEFF:
I'm not an expert on the subject but if you're using safestrap that means that your bootloader is locked meaning you should have received the update via OTA.
[AT&T Samsung Galaxy S 4 General] :
You probably won't get the OTA being rooted. And if you take it, you will not be able to re-root atm.

You will need SafeStrap 3.71

Read OP page--it addresses it part way down page. I don't think flashing NB1 will matter as I flash any radio any rom. But, you never know. Have a nandroid with SafStrap stored on your phone and pc.

Someone else can confirm this please--:)
[AT&T Samsung Galaxy S 4 General] :
I have installed safe strap. I have downloaded the NB1 modem. I dont really care for back ups, I dont have anything valuable on my phone besides my settings

Is there a chance something can go wrong?

Damnit, so there's no way I can get LTE on my device, and hopefully have better battery? Cause for some reason, my battery drain is unexplainable, and I can find nothing odd on the BetterBatteryStats log.

I'm pretty sure that the hardware radios are the same,only the firmware and software controllers are different. Is there any way I can enable AWS bands on the i9505? There was one thread for T-Mobile about unlocking AWS, but apparently it didn't work on i9505...

I have I337 with MDL BL, ROM Omega24, kernel KT, LOKI

NB1 GSM modem works. If I flash NB1 LTE modem everything work including 3G, LTE, WIFI.

There is only one problem: no sound.

Can anybody explain me why? Is any way use NB1 lte modem with MDL BL?

Thank you.
[AT&T Samsung Galaxy S 4 General] RockRatt:
Not sure of your sound issue. That shouldn't be related to modems at all or the modem zip files.

I as do many have the MDL (or in my case mdb) bootloaders. I am currently using the NB1 modem right now.

Maybe a dumb question but first WHAT sound do you not get? Sound when you made a call and others cannot hear you? Or you cannot hear them? Or you have no sound at all on your device not relating to calls?

I just saw your post in the q&a section as well. OK just to be sure you have a ATT VERSION of the i337 correct? If you have the i337M then these shouldn't work at all for you.

[AT&T Samsung Galaxy S 4 General] svs57:

[AT&T Samsung Galaxy S 4 General] RockRatt:
Okay have you tried any other 4.4.2 roms? I am currently running ShoStock-i with mdb bootloaders, NB1 modem and have no issues at all.

I believe the ROM your running is a i9505 based ROM, have you tried anything else like changing the CSC files to ATT version? Possibly something in the ROM needs updating to be able to not have sound issues. There has been 163 downloads of the NB1 modem in my OP. So since this is the first I am hearing of anything like your situation I would lean toward a ROM issue or a kernel issue. The modem should have NO EFFECT on sound of the phone at all (other than possibly not having a good signal on your phone and having issues with calls... possibly).

I'll try to ask Omerga forum about this issue.

[AT&T Samsung Galaxy S 4 General] RockRatt:
You are using the NB1 modem in the OP of this post correct? It is a LTE modem and yes I get LTE, no WiFi issues, no sound issues at all. I know it is hard to see with my modified 4G LTE icon but I am getting LTE in my area of the US.
[AT&T Samsung Galaxy S 4 General] svs57:
Maybe there is some misunderstanding between us.

NB1 GSM (mdm -> /dev/block/mmcblk0p2) and MDL LTE (apnhlos -> /dev/block/mmcblk0p1) sound, wifi, lte work

NB1 GSM (mdm -> /dev/block/mmcblk0p2) and NB1 LTE (apnhlos -> /dev/block/mmcblk0p1) no sound; wifi, lte work
[AT&T Samsung Galaxy S 4 General] RockRatt:
Okay I kind of understand. I never have flashed the non-hlos and haven't put them into these zip files. I could upload a test version for you that includes the hlos file? EDIT: I thought I had the non-hlos but I do not. I will either need someone to pull it or wait until I can do the patch for it.

Slow, laggy

I'm on Omega Rom 18 TW 4.3, installed the NB1 modem and the phone became slow and laggy. Apps worked fine, just scrolling on the launcher was just real stuttery and some widgets wouldn't show up. Went back to MK2 and back to normal now
[AT&T Samsung Galaxy S 4 General] RockRatt:
Well that is REAL WEIRD as the modem doesn't have ANYTHING at all that would effect that. The modem gets installed to a seperate partition inside the phone. It has no correlation to any apps/system functions (except mobile data). I do not even know what to tell you to try as this is the first I have heard of anything like this and there have been 263 downloads. Maybe something with the way Omega is set up?

RockRatt, are the flash_image and update-binary files device specific?
[AT&T Samsung Galaxy S 4 General] RockRatt:
I haven't tested the updater_binary or flash_image on any other devices to know. What device do you have?

If you are wanting to flash these modems onto a different device than the ATT i337 I would advise against it.

If you are wanting to use the zip as a template and add the correct modem for your device then you can try. But again I would be careful to make sure you can flash your original modem back on.

If you wanting to flash modems with the zip for the i337m it will not work, as far as I know the i337m can ONLY flash via Odin/mobile Odin.

I substituted the modem.bin with the one for my device, its an sgh-m919 (tmo). I find it quite odd that my i337 can flash modems rather easily through cwm while I can't on the m919. Is there a reason for this? I would have thought it would have been the opposite considering the lock on the bootloader the i337 has. The flash goes through without errors, but the baseband does not change. I just ended up flashing my modem.bin through odin.

I see you are using flash_image, is that a busybox function? Do you think using busybox's dd on a cwm script would make a difference?
[AT&T Samsung Galaxy S 4 General] graydiggy:
You have to use Odin to flash modems with the TMO variant. I think it has to do with how the recovery handles it or can't handle it really...
[AT&T Samsung Galaxy S 4 General] RockRatt:
I received a PM about flashing a modem/updating baseband and the worry about locking the bootloader to a different baseband. Flashing Modems does NOT change your BOOTLOADER and does NOT lock it down further.

So if you are on MDB or MDL and use Loki flashing these will NOT change that and you can STILL flash anything your heart desires.

If you are MF3 BOOTLOADER flashing these will not UNLOCK/LOCK DOWN further your ability to use Safestrap and flash its compatible roms.

If you are on MK2 BOOTLOADER these will NOT UNLOCK/LOCK DOWN further your bootloader so you can STILL use its version of Safestrap to flash any compatible Roms.

BOOTLOADERS are what lock the phone down. Not the BASEBAND. So you can check your BOOTLOADER with easy directions in the OP so you know WHAT and HOW TO with your phone.

Check out the "HowTo" to check WHICH bootloader you have on your phone from the OP.

[AT&T Samsung Galaxy S 4 General] Moostafa29:
So you flashed the modem to one of the slots, and not the stock rom correct? This keeps the stock rom on mf3, thus not breaking safestrap, but also allows us to use 4.3 based roms on one of the other slots?

Interesting. I may try it out. I've been wanting to use some of the 4.3 roms out there, but I feel like I'll shoot myself if I mess up the ability to use safestrap and flash lol.
[AT&T Samsung Galaxy S 4 General] Easton999GS:
Oh my god... if anyone here is on safestrap, The radio is seperate from the rom entirely. We can flash these on safestrap however we want. We cant run any 4.3 roms because we dont have signed 4.3 kernel. Unless we can get kexec which redirects the kernel to a custom one or a bootloader unlock where the kernel doesnt need to be signed we are going to be stuck with the 4.2.2 MF3 kernel. Our only other choice is to upgrade to 4.3 and hope to god that there is root and that safestrap isnt fully patched. But im going to stay on 4.2.2. The 4.3 bootloader is hell on earth and tighter than fort knox. SELinux is set to enforcing?? no way. Right now MF3 is the last bootloader for any hope in getting kexec and a bootloader unlock somehow because Sammy just stepped their game up big time.
[AT&T Samsung Galaxy S 4 General] Venom0642:
Nice to bad no one has made the Stock Kernel for 4.3 yet!
[AT&T Samsung Galaxy S 4 General] Easton999GS:
This modem ****s on my battery life. I have a theory that the bootloader and the radio talk to each other, Ive been through about 5 galaxy s4 phones due to different issues and ive had all of them rooted. With the MDL bootloader if I flash MF3 radios the battery life sucked but if I stayed on MDL radios it was amazing. Now on this replacement phone im stuck with mf3, If I flash MDL radios the battery life is trash but on MF3 its actually amazing. So with these new radios and the old MF3 bootloader I feel like this issue is reoccurring again. I have a friend with VZW who is on MDK who notices the same thing as I do when he flashed the ME7 radios.
