[Q] Galaxy S4 SGH-i337 4.4.2 root help!

Sorry if I posted this in the wrong place or if there is already a thread about this. If there is, I couldn't find it. I really want to root my phone to use it as a mobile wifi hotspot for my tablet and I am having a really hard time trying to find a link to a forum or a youtube video about how to root my phone. So far, I have only found root tutorials for models other than mine. Do I just have an obscure phone model or is it just more difficult to root? I have wanted to do this for quite some time now so any help is appreciated!

4.4.2 is a new release so currently there is not a root method. As of my last reading there is some significant progress in finding a root method. This is definitely not an obscure phone model. Just a brand new update that developers are still working to root.

Is there any workaround for this, as this seems like a pain not being able to mount system in recovery.

This is the only option. All you have to do to mount system is a quick flash of one package in ODIN, and then you just have to do another ODIN after you finish flashing in recovery. It's not that bad really.

Ehh, I want to upgrade but it just seems like a pain to be tethered to a computer when you need to flash. Maybe I'm making a big deal over nothing, idk.

Not being able to flash and restore backups on the go definitely is a downside, so this definitely isn't for flashaholics or people who want their flashable mods wherever they are. It's a matter of whether you're willing to take time to set it up stable all at once or just chill back until things are updated (root method and safestrap namely)

Yeah, i tend to flash quite a few zips on the go, and not being able to is a big downside.

Hello. I have the same problem. I am trying to unlock my sgh-i337 with Android OS 4.4.2, but first wanted to root it. I was able to install the superuser app but when launched an error pops upon installation. Help anyone?

You need to a lot more reading in the general forum. What firmware are you on? You can't just install super su from the play store which I'm assuming you did. If I'm wrong please correct me

How do I check the firmware? The baseband version is I337UCUFNB1.
Yes, I have installed the Super SU from playstore, but before I have used a root_sgh-i337.bat file.

I would prefer to get code from at&t, but have to wait 48 hours for them to get back to the guy who sold the phone to me. I'm keeping my fingers crossed. If they refuse to provide the code then I will have to mess with the phone to get it unlocked or sell it as is.

[Q] How to Update from MF3 to Kitkat

How to update from stock AT&T 4.2.2 (i337 MF3) to kitkat?
Do I need CWM or can I use safestrap?
I prefer to flash directly from my cellphone since I can't use Odin because I have a Mac.
Thanks in advance! :good:

That is not correct. I did some reading and I found the information I was looking for.
I was able to update my stock AT&T i337 4.2.2 (MF3) to stock AT&T i337 4.4.2 (NB1) without using Odin.
This is a very easy and simple procedure that doesn't require root nor custom recovery. In fact, it will only work if you have stock AT&T (no root, no custom recovery).
First, update to MK2 using these steps:
http://forum.xda-developers.com/showthread.php?t=2573080
Then, update from MK2 to NB1 using these steps:
http://www.theandroidsoul.com/att-galaxy-s4-sgh-i337-android-4-4-2-kitkat-ota-update-i337ucufnb1/
Great solution to those who missed the AT&T OTA. No root needed, no unlock, no custom recovery, just the stock recovery. Beautiful!!!

Good job, I'd forgotten about the update.zip

Thanks. It took me about 4 hours of researching and reading to find that.
There are too many solutions and ways to do things which just make it more difficult for us to do a simple task.

[Q] Updated to 4.4.2 KitKat any Rom suggestions?

I recently updated to 4.4.2 KitKat on my AT&T Galaxy S4. I am rooted with safestrap installed. I am new to Androids and I was wondering if there were any roms available for baseband I337UCUFNB1, I found GoldenEye but it won't work on my baseband without a certain file being flashed through Odin first, every link I have come across to download this file ends up saying file not found. Are there any safe roms out there that I can use? I've searched all over and found some, but it's just kind of confusing to me. Thanks in advance!

Yea i've been there, I'm just really confused on the whole process is all. It says something about going from NB1 to NC1, but the roms it lists aren't for either one of those basebands but it still says they'll work. I don't know if I want to risk it lol

You're not going to brick your device. You may have to Odin back to nb1 in the worst case. Do the ota to nc1 and root with towel root. Then use safestrap.

Am I able to downgrade from NI1 to NB1?

I was just wondering if I could downgrade the firmware safely because I want to Sim unlock my at&t s4 so I could use it with my T-Mobile Sim card.. ?

You can safely downgrade. To Sim unlock, you don't need to downgrade.

Yes you are able to. Have done it.many times, just download the NB1 firmware and flash via Odin. Hope it helps.

All required info in All Things AT&T
Steps:
1. Root (read root section of the thread)
2. Install safestrap v3.72 and install recovery using the app. You may have to use selinuxmodechanger app to set selinux to permissive if the recovery installation doesnt work
Reboot the phone and safestrap recovery can be accessed from the splash screen that will be shown during boot.
3. Flash the MF3 modem from safestrap recovery (link to modems available in the ATT thread)
4. Reboot the phone and run regionlockaway app. This should successfully sim unlock the phone for you.
5. You can flash back the NI1 modem in safestrap recovery.

Will be doing this now. Will let you know when I get working

[Q] GALAXY S4 ATnT 5.0.1 OFFICIAL NEED HELP HERE!

My playstore not working said. " cant initialize...."
I know the cause of this is the freedom. I used freedom when im in kitkat official. Im also rooted that time. Then i forgot to delete the "host" file before updating. Now my "at&t galaxy s4 is 5.0
1 official" can someone help me root this device pls. To fix this problem ? Or any fix/method to this problem without root ?
I also dont know what is lock and unlock bootloader, even how to check if i have lock or unlock bootloader. What does it mean if i have lock and unlock bootloader
Note: my galaxy s4 is at&t 5.0.1 not rooted.
My galaxy s4 at&t can read any sim card because its already factory unlocked.

First, freedom is warez. DO NOT USE IT. To get you're phone working properly again you'll most likely need to flash the nb1 firmware in Odin. You can then work on rooting your device and getting back to 5.x. But you'll have to read this very carefully first, http://forum.xda-developers.com/showthread.php?p=53758227

All at&t i337's have a locked bootloader. So don't worry about that. Carefully read the link I gave you. Yes it's long and yes it's going to take a lot of reading and re-reading before it makes sense. And yes you can downgrade to kitkat, nb1, and yes you can have root on 5.0. Look at how to flash nb1 in Odin, how to update to nc1 and root, and how to keep root to oc3, 5.0.

The people who contribute here donate their time to the forums. Usually, they do it because they like to help others. For many it is like a hobby.
However, there is already a lot of information collected here on the forums. Most people don't really enjoy saying the same things over and over. And besides, it is not really very polite to ask someone hold your hand, when you can find the information and process it yourself.
Most people here would say, if you can't understand the directions, then you shouldn't probably be trying to modify your phone. So, to re-iterate what jd said, read the instructions, read them again, and again if necessary. Only proceed when you understand what you are doing. If something doesn't make sense to you, ask a specific question and someone will be happy to explain.

You should flash nb1 using desktop Odin. This will return your phone to fully stock I337UCUFNB1 which is KitKat 4.4.2.
You may also want to read through this thread several times.

Is the nb1 is universal ? I mean, how can i know if this fits in my device ? I337 att
Can i use any versio of odin ? Or the latest ?
Thanks alot. Ill try tomorrow. Its 1am here thanks bro. But just for now ill look for nb1 download link

nb1 is shorthand notation for I337UCUFNB1, as I said in my previous post. The first part (I337) tells you that it is for your phone.
