I have an AT&T galaxy s 4 SGH-1337 that i'm using on the t-mobile network.
It's unlocked and i've changed the setting to allow 4G on t-mobile (AWS).
I have an update available but i have to put in a AT&T sim to get it. If i do the update, will it re-lock the AWS band?
Phone is completely stock and not rooted.
Thanks
Edit: To clarify, i'm not to worried about the minor updates, but i'm mostly asking about the android 4.3 upgrade that samsung will push out in a few months.
if the update has a baseband update, then yes... else, no
If you put in an AT&T sim card and grab the update it's gonna be the MF3 update. Yes it will remove the AWS band.
I was on mf3 and had the aws band unlocked, when I messed up my phone Samsung flash mf3 again for me and aws was still inplace

I don't understand how since that method they definitely flash a new modem along with the stick ROM. You can always update it and if aws goes away put it back.

Has anyone tried this on the ATT Variant? I understand it clearly says TMo and Verizion, but we know what often happens when you ASSUME they will work on something not listed..The model numbers are not all the same but it "should" be compatible with the TMobile version.
Hi - I have bought an AT&T S4 with the following version:
4.2.2
I337UCUAMDL
I did the XDA method for unlock, it worked great. Then did super root and it worked, also installed TWRP. I've also done the AWS band unlock.
Now, the biggest challenge, which rom do I install for the stock T-mobile features? Mainly I just want a stable rom with T-mobile wifi calling.
I would appreciate the help.
Thanks!
Read the OPs of the Roms in the T-Mobile S4 section.

I just recently acquire myself a Sprint Galaxy S4. It is not rooted. It is running stock android 4.3 with the L720VPUEMK2 baseband. My question is can I unlock this phone to use on US gsm carriers like Tmobile and AT&T? I don't want to buy any unlock code from ebay because those codes only allow it to unlock to use for overseas. Have I had a choice I would've just bought a Tmobile, AT&T or verizon galaxy s4, but they were too expensive. Can anyone help me?
Pls read next time, anyways no you can't as of right now because only works with mdc or mdl basebands and no way to downgrade right now...mf9 and above you can international unlock tho

Darn it!!! So what you're basically saying is that even if I rooted the phone and use a rom that supports MDC or MDL basebands I still can't unlock it to use on domestic GSM carriers? If that's the case if i'm reading correctly then I guess it's time to put up the phone for sale on Swappa.
I think that because you can't downgrade to MDC/MDL baseband you can't unlock it in domestic GSM carrier at least currently.
The knox in bootloader denied you to downgrade to MDC/MDL baseband.
So either wait to get a solution or sell it.

Some users tell that they can downgrade the baseband easly to MDC/MDL baseband only.
so if you can you can unlock GSM.
Note:downgrade the baseband only ....neither the software nor bootloader.
So I've read the stickies and posted in the forum but I need yk see if anyone can help me out with LTE. I have att service on a stock non rooted n4 I've dialed *#*#4636#*#* changed my network type but it doesn't stick so I can't select lte in my settings and I'm not getting it regardless of my APN settings ... Anyone have any ideas of what's going on outside of rooting and flashing a different modem or radio .. Any help is appreciated ... Thanks

You need to flash a hybrid radio unless you never updated past stock 4.2.1,
newer radioes have the code disabled since it hasnt been approved by the FCC for LTE

The Nexus 4 does not support all of the AT&T LTE bands. It lacks the most commonly used LTE bands for AT&T and therefore can only be used in a couple of cities. If you do live in one of those cities, you need to unlock the bootloader and flash a hybrid radio.
OK I've been reading and I'm a little confused is there a solid working root and bootloader unlock for 4.4.2 ?

You can flash any baseband (aka radio) you want but, in order for LTE to work, you will need to flash a hybrid radio. For 4.4.2, you would need radio version .98 or .97
There was a recently released app that makes installing or changing either the hybrid or stock radios extremely easy. I used to use the manual method until this came along:
http://forum.xda-developers.com/nexus-4/themes-apps/app-nexus-4-modem-flasher-lte-enabler-t2607221
As was also mentioned, AT&T Band 4 is not available in too many areas, so don't be surprised if you never get LTE.
I have an i337M S4 from Rogers and it's unlocked. It works on Wind too(Going to guess the seller flashed that AWS mod).
Can I go ahead and just flash a modem TAR and a bootloader TAR from Odin(WITHOUT losing Wind 1700AWS support)? I want to update my modem and BL because they are old now. I backed up my EFS using TWRP but pretty sure that is not the modem.
Help please
Flashing with odin will not re-lock the sim. Once it's unlocked it'll remain unlocked

I think you didn't get what I was saying. This thing has an AWS mod flashed into it.
