[Q] NOOB trying to unlock AT&T S4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have an AT&T Galaxy S 4, SGH-I337 running Android 4.4.2 and I want to unlock it. I haven't had any luck with doing it my self through the Service Menu, I guess due to KitKat.
My question is If I use Towelroot to root my phone, will I be able to unlock my phone and use on T-Mobile?
Thanks for all the great stuff on your site!

Have you tried this? It's in the general forum

Can a new S4 from ATT carrier be rooted?

Saw a good deal for a new Galaxy S4 for $79 + $70 trade in on my old HTC One. So only $10 for the New S4: )
But reading around people saying the New S4 firmware has a hard lock on it and not easy to root and only one or two roms working on it?
I was gonna root it and put the Google Play Edition ROM on it but some say that's not possible on new S4 from ATT carriers now?

You should do some searching but the s4 with mf3 can be rooted. I know they're not going to have the the new 4.3 update on it yet. But I'd say get the s4 and use the kingo root method.
Use this guide for rooting

Root doesn't mean unlocked. You can be rooted and still have a locked bootloader.did you read before posting? I'm not trying to come off rude.

You will be able to root the AT&T Galaxy S4 easily, almost everyone here in this AT&T S4 forum
already has rooted their phones and have flashed custom roms without any issues.
Good luck!
MF3 can be rooted but you can't flash a custom recovery (TWRP, CWM) If you're asking if you can root the device and flash a custom rom, it all depends on your AT&T store. Try and go to your AT&T store and before they unbox the S4 and start activating everything, make sure you tell them you want a phone with the firmware MDL on it. If they don't have any with the firmware MDL, tough luck. If you get an S4 with MF3, you can only root.
Not only root.
Root it and install Safestrap to install most TW based ROMs that run 4.2.2
Most important is to lube your eyes and
READ/SEARCH all info to do with your build or you will be a victim of the I bricked my phone cause I can't read.you can Google anything to do with your phone and ad "xda" to the search and you will find what you are looking for.

Last two phones I had, the Nexus 4, and Note 2 on ATT, were easy as pie to root and install recovery, and that was it, you were done forever, just flash a ROM + Kernel, reboot and bam you had a fresh new ROM to enjoy, and was so easy and fast to do get it installed, was a no brainer. What happened in the past year with phones being so locked down so hard, where you can't just do that anymore ?
Wish all Android phones were as simple as a Nexus to flash rom's on. But I don't want the Nexus 5 phone with tiny battery, I like bigger batteries or removable, and more storage options, etc...
Yes it can be rooted using the external sd card method. Its actually easy to do.

Thank you. So I can root it no problem, but then it's a matter of very select ROM's available due to my firmware ? And none of them can be 4.3 based ? Which the S4 doesn't even officially have yet, but not even the Google Play Edition ROM that is 4.3 can be installed on this firmware, only the older 4.2.2 version ?
Ok, so I root with using 'Kingo' method
Then install the safestrap .apk, and install that
And then install only a ROM on the provided list, which will all be 4.2.2 based only ? Still rather have any of those, than just stock TW out of the box unrooted
All correct

You can put Google play edition ROMs on but not the 4.3 as stated in the guide. The only real problem for me is that it seems to use more battery than tw roms. And you don't have all the features as your tw based ROMs on the gpe ROMs. Some tw ROMs are just as fast if not faster. Fast speeds and great battery life can't go wrong with that.

You guys recommend a new S4, or the LG G2 ?
Thing is the G2 development is very sparse, and cases and accessories few and little for the G2. And what about resale down the road in a year or 18 months ? Which will fetch better trade in money the S4 or G2 ?
Thanks.

[Q] Which T-mobile Rom Wifi Calling for AT&T S4?

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'm sure you can carrier unlock your S4 and allow you to use another Sim card. Try searching for it

I think you can carrier unlock for 3G data only. But I think Sprint has to give you the code, and you have to be off contract or paid up on your phone.
If you look around you will see the domestic unlock only rolls when you are on mf9 bootloader and can go back to mdc If you are on 4.4.2 the best you can do is foreign unlock after 90 days on Sprint and then they will unlock it.

hi guys

Hello, I just got a s4 and I love it. Where I got it said it is unlocked. Now how can I check to see if it is truly unlocked. Also is there like a easy guide to rooting it?:laugh:
Try a different carriers sim. It's the only way to check if it's unlocked
