LTE on T-Mobile is Band 4 so I'm not sure why you're picking 7. Automatic is fine.

Currently rocking KOTH49H.140116 with a UCUAMF3 baseband on my i337 (currently branded as GT-I9505G). Will flashing the latest MK2 AT&T modem break anything? I'm just hoping that the newer modem might give my signal some boost... Also, I understand that I might lose the possibility of AWS modding, which so far I have no use for. Is that so?
[AT&T Samsung Galaxy S 4 General] RockRatt:
You can try any of the modems and they will NOT break anything. Newer or Older Modems for that matter may work better for you. Modems work BETTER/WORSE depending on your location. So what may work great for one person lets say in California nay not work as good for someone else in Arizona, and what works best for someone in New York may or may not work as good for a person in California. It just depends on WHICH MODEM works best for YOUR PHONE IN YOUR AREA.

Many thanks! I flashed the MK2 modem and I am liking the results! Now if only I could get some advice as to what ATT APN to choose, I'd be all set. I got quite a few choices, though I can't really tell the difference b/w them. By default the ATT PHONE has been chosen, though I got others that sound more promising, such as ATT LTE and ATT Broadband. Any advice as to which one to choose?

Many thanks again!
[AT&T Samsung Galaxy S 4 General] RockRatt:
I have always used ATT phone. But I haven't messed with apn's in quite a while. I did use the huspa+ version on some international based Roms before when my LTE 5Gb limit was throttled. Then I would get an extra 3Gb of data untrottled. Usually that would last for me for my billing cycle.

Bit I haven't changed apn's in a long time. Do you see ANY difference when using different apn's? Try each out for a day or so and let us know if one is better for you than the others.

[AT&T Samsung Galaxy S 4 General] RockRatt:
If users want to add their State and which modem works best for them I can start adding them to the OP, and hopefully stay on top of it. I do think it varies from State to State, County to County, and maybe even Phone to Phone. But it MAY help others try out certain modems rather than flashing them all.

On another note the modem zips are very small file size wise. Nothing extra needs to be done to flash them, I never wipe ANYTHING. I just flash it in recovery and go with it. So it really only is a matter of 30 seconds to a Minute from flash to phone rebooted and your on your way. So testing out a modem in your area for a day to see how it works, then testing a second modem the next day, and so on until you personally find what works best for you/your area/your phone would not take a long period of time.

It is NOT always necessary to flash the newest modem. If you have one that works great already you can always keep using it. For me MDB or MDL are still one of the best for me no matter which ROM I am on. MK2 I think was the worst for me. So flashing modems should mainly be if the one your on has some issues, then you try another that may work better/worse for you and your phone. Speed test can vary between modems, but yet again what works GREAT for one may work like crap for another. So that is why I say to test them all out and see which works best for YOU.

Understood, I meant no disrespect nor meant to say your recommendation was incorrect. Thanks for the consideration
[AT&T Samsung Galaxy S 4 General] RockRatt:
Don't get me wrong. I think it is a good idea. It probably would help others choose more wisely which modem works best for them if they see someone in there area posted how good it worked.

I was trying to further explain what I think goes on with the modems and why you will see people post how great one modem works for them and another saying it was worse.

We all know not each phone has the exact same hardware, I learned that from my S1 and S2 days. How kernels worked for some and not for others. People with certain revisions this would work, and others on other revisions other thing would not work. Like my S1 never had any GPS issues but some users with newer revisions GPS never worked while even newer revisions did work. It was kind of a crapshoot. How things would work sometimes.

You also can't go by the bars. Some roms use 4 bars...some 5 bars... and like mine uses 6 bars.... and we have done some adjustments to them. We make it more realistic and evenly spread. Nothing pisses me off more when a phone shows full signal at only -90db.
[AT&T Samsung Galaxy S 4 General] Droidmissionary:
I agree which why I suggested listing how many were available as well but I was unaware you all could modify how they reflect the signal, thanks for the input shoman94

I think to prevent a domino effect and keep the thread on topic it would probably be safer to leave it out based off the amount of variables which in turn could trigger other variables such as ROM and carrier relations. Ty for hearing me out though rock
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Wanam XPosed lets you change the number of signal bars. I have it set to 5 I think. I like accuracy. 4 is for people who want to feel better about low signal (or worse if it's really bad since it'll display fewer bars for better service). 5 is accurate. 6 is compensating (Sprint sets their phones to 6 bars) for crappy signal.

MLD -83dBm

MJ6 -84Bm

MDB -89dBm

MDL-88dBm

MF3-89dBM

MJ9-89dBM

MK2-89dBm

I laid the phone on a table to ensure that all variables are equal. I started off with MLD, flashed in the order above, then ended with MLD. The last reading for MLD was -84dBm. However, MLD is currently showing -89dBm (the phone is sitting on the same table/location). Interpret the results however you want. If i get bore, I'll test another modem.

Update: per shoman's advice, I tested these again. They are all on LTE. Frequency is 700 for all as well.
[AT&T Samsung Galaxy S 4 General] WackyJoe:
Hi...

Curious...do you also have the i537 (S4 Active) modems as well?

Or will the i337 modems work for the i537?
[AT&T Samsung Galaxy S 4 General] shoman94:
When you post results like this you should be using *#0011# as it allows you took also post the technology being used (ie hspa or LTE )and also the frequency (ie 850 or 1900) because that matters.
[AT&T Samsung Galaxy S 4 General] RockRatt:
No. They would have to be pulled from the firmware for your i537. I don't have a i537 so I couldn't help.

As far as I know (I would almost bet on it) the answer is NO you couldn't use these modems on a i537.

[AT&T Samsung Galaxy S 4 General] HORiZUN:
So here's my setup: SGH-I337, Rooted, SafeStrap, MF3, Hyperdrive 10.2 with compatibility pack and MF3 modules.

Here's what I did: I followed the tutorial in the sim unlocking thread to flash the MDL modem, accessed the service menu, and sim unlocked the device. Rebooted and things started running weird in the ROM, so decided to do a clean wipe and reflash. All is good.

Here's my question: Can I flash a newer modem, MK2 for example, and retain my sim unlock? I'm about to head to Europe for a few months, and I've read about signal reception improvements just by flashing a newer modem - I just don't want to lose my sim unlock. I'll be relying heavily on it, soon.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
SIM unlock is permanent so yeah.
[AT&T Samsung Galaxy S 4 General] HORiZUN:
So I flashed the MF3 modem back with Odin after the unlock with the MDL modem. Inserted a T-Mobile sim card, turned on the phone to be prompted to enter network unlock code. It says emergency calls only. Im still on MF3 firmware.. Whats going on?
[AT&T Samsung Galaxy S 4 General] Product F(RED):
That's odd. Not really sure. I did the unlock the way you described it and it worked fine for me. I'm using mine on T-Mobile and I'm on MF3 modem.

[AT&T Samsung Galaxy S 4 General] HORiZUN:
Must be nice to have an option other than safestrap, not that I'm ungrateful, but I long for aosp on this device.

Mine shipped with MF3. :(

Edit: I downgraded the modem to MDL again and accessed the service menu. When you get to the network lock steps my phone says SHA FLAG 256 (0) already set, so that makes me think the problem lies with the sim I'm using to test. It's an old T-Mobile sim a friend of mine had laying around. I'll try tomorrow with an active service subscription and see how it goes. It makes me think that the unlock has stuck through a wipe, flash, modem upgrade, and downgrade!

I hope it works..

The newest modem is horrible for me. I have been on 3 different ROMs and all show the same results. Crap. AT&T really screwed up on this one.

Blame Samsung. They suck at writing RIL software (the code that connects the modem to the rest of the phone).

Hopefully you made a backup of previous rom that had gps working if so flash that backup test and see if your gps works on it if it does which it should leave gps turn on in toggles then go back to recovery flash the new rom you want and see if your gps works after doing the above.

Trying to Unlock i337 mk2

Hello, I've been searching everywhere to find a solution to unlock my i337. I'm on 4.3 mk2. All the youtube videos don't show the same options that I go through. I'm wondering because I've done all the OTA updates and it's been locked out.

Verizon is CDMA. ATT phones are GSM
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Verizon phones actually support GSM nowadays. All of their LTE devices come factory unlocked due to an agreement with the FCC about being able to use their current LTE frequency. A Verizon Galaxy S4 will work on AT&T EDGE and HSPA+ out of the box.

But not the other way around. An AT&T Galaxy S4 won't work on Verizon.
[AT&T Samsung Galaxy S 4 General] Product F(RED):
Correct. However, the phone can read the SIM card and identify the phone number on it (I've tried). But like you said, it won't connect to the network. It actually will connect only to the LTE network in areas where Verizon has rolled out AWS LTE.
[AT&T Samsung Galaxy S 4 General] bjybhs8:
Possibly Success?

OK, I didnt know that. I was just trying the only other SIM card I had available. Will a T-Mobile SIM only work? My co-worker is on Sprint, what if I try his SIM?

What I am trying to do is unlock my S4 i337 4.3 MK2. Method 2 shown in the first post was successful in changing my Baseband to MDL from MK2. Since I only had a Verizon SIM, I tried it and no luck, or at least that's what it was saying. I just flashed it back to my original Baseband MK2. While I was on MDL, I didnt have wifi. My wifi is back, but does that mean I'm unlocked?

When I was on MDL, I did go through the Service Mode and finally saw the hidden option [6] Phone Control which allowed me to follow the entire process where Golden something exist to restore to.
