[Q] Did the Guide Phone still NOT rooted

Hello everybody,
I am pretty new to android, always had iPhone before, and JB was very easy for me.
Now I am trying something new I got a S4 from "ATT", it was already unlocked when I got it. Using H2O as a provider.
Reason for me want to root my phone is so I can screen record on my phone and need root permission.
My Current firmware version: PDA:MK2 / PHONE:MK2 / CSC:MK2 (ATT)
I really don't know where to start about this rooting, I tried to fallow http://forum.xda-developers.com/showthread.php?t=2283918 and http://androidtechy.com/index.php/2013-04-28-19-55-53/how-to-diy/48
How to root:
Download root explorer or EsFile Explorer
Download the Root Exploit Here by XDA Developer djrbliss
Download the GS4 Drivers here
Ensure USB Debugging mode is enabled on your device.
Connect your device to your PC via USB.
If you are using Windows, navigate to the extracted directory and execute "run.bat". If you are using Linux or OS X, navigate to the extracted directory in a terminal and execute "./run.sh".
Approve the ADB connection from your PC on your device.
Reboot and check if you have root using the Root Checker app from the PlayStore
Note: If you dont have root the first time, go back to step 5 and try again.
I've been doing that but ROOT CHECKER still says that I don't have root. (Tried run.bat) 3 times. said I already have Root.apk on my phone.
Is this the only way to root my phone, or is there a newer way since those guides are from 2013.

That's why you should stick to guides here and not some random online guide. Search up easy Root and be done

You have an unlocked ATT phone? How did you go about that? when you say unlocked, what? the sim unlocked?

H2O runs on AT&Ts network, so it runs just fine on a sim locked AT&T phone. I wonder if the OP thinks the phone is unlocked because of that? The best way to find out is to put a Tmobile sim in it.

Not getting Ota for 4.4.2 and kies doesn't work (battery issue)

This is my mom's phone and she is getting less than 2.5 hrs screen on time on the note3.
I'm with T-Mobile and currently the phone is on 4.3. The Android os is keeping her phone awake and now the battery life is worse than before. Now it's less than 2hrs SOT
So I thought I'd update it and it just says "software update is temporarily unavailabe. Try again later"
OK, no problem since I'm not using it with Verizon I figured I wouldn't get the update but it was worth a shot (since update is pushed thru Verizon and not samsung)
I tried to use kies 2.6 and it says use kies 3.0. With 3.0 it says device is not supported.
The phone is not recognizing it being plugged in as a USB there is no USB option in the notification bar that allows it to be toggled between mass storage and camera.
I'm using the v8 v9 USB from my nexus 4 and used my galaxy 4 USB (don't have the note 3 one) (just ordered one) could it be because I'm not using the new 3.0 USB?
Everything is stock not rooted

try going in to settings, about phone, build number, tap build number repeatedly til u see developer options unlocked, go back to settings into dev options, and turn on usb debugging, plug your usb back into your computer to see if other drivers download to get kies workin.

What did you have to do for that just put tmo SIM in and you are good to go?
My quandary is t mobile note 3 have unlocked bootloader Verizon has a locked down bootloader t mobile also has a wider feature set and better rom support. Tmo network just sucks though.
What I would do is factory reset the phone root it install safestrap and one of the custom roms and I would not bother trying to odin nc4 onto it.
If your dead set on a stock experience you're going to have to download a stock nc4 image and use odin to upgrade I advise against this as it runs the risk of tripping Knox rooting and rom is a smaller risk but still a risk. But the other disadvantage is nc4 is not rootable.

you're not getting the "Over The Air" update because you're on the wrong air. TMobile won't push a Verizon OTA to a Verizon device on their network.
You're best off rooting the phone and installing the NC2 KitKat leak+firmware - it's stock KitKat, rooted.
On your current setup you can use Kingo for root (just google it)
Install safestrap 3.65 from here - http://goo.im/devs/Hashcode/note3/hltevzw/safestrap (the main safestrap thread is here - http://forum.xda-developers.com/showthread.php?t=2517610 ) ...

[Q] i337 SIM Network Unlock Assistance

Since no question is "too stupid", I am hoping someone can help me out. My goal is to unlock SIM and switch carriers to TMOBILE. I have a galaxy S4 I337 4.4.2 with ATT. It has the stock rom. It was never flashed, only rooted.
Samsung -SGH-I337
ATT
Firmware version I337UCUFNC1 (ATT)
4.4.2
The phone is rooted. Here are steps I have done so far.
- Rooted phone
- Ran RegionLockAway app
- Entered the service menu, trying to turn off the SHA256 flag to off, but I don't have that menu. Phone only displays 2 options at Network Lock menu - SHA256 info and flag info
- Requested unlock code from ATT and they denied me stating 2 year contract must be fullfilled first. Phone is 14 months purchased. (BullS#$T)
- Purchased an unlock code for $6 from an advertiser on this site, but was told one couldn't be generated and they did refund my money.
I did search in this forum but did not see any threads addressing the i337 US on my firmware for unlocking the sim on my phone. I would be happy to post anymore info if needed. Thank you.

Regionlockaway works on the MF3 modem. So, install safe strap recovery and flash the MF3 modem(link available in all things Att thread) http://forum.xda-developers.com/showthread.php?t=2595457
You would also have to enable AWS bands - http://forum.xda-developers.com/showthread.php?t=2291589

Thank you for your help. I appreciate it. I am pretty new to this, so I have a question. There are 2 methods. Which would be relevant for my phone? Would it be method 1 since it is 4.4.2? Also, would mine require a downgrade to accomplish what I am trying to do? Thanks again.

You would have to set selinux mode to permissive. You can use selinuxmodechanger app.
You need to install safestrap recovery using the safestrap app. Install version 3.72. Install app. Open the app and click on install recovery.
Safestrap recovery is a modified safe version of TWRP for our phone. It doesnt replace the default recovery but is available in normal boot mode. You would see a splashscreen on bootup with options to enter recovery or continue (using the capacitive menu and back buttons).
You would use safestrap recovery to flash the MF3 modem.
The downgrade method was mentioned due to the fact that we didnt have a root method for kitkat until towelroot came out.

[Q] Can't unlock rooted sgh-i337 on 4.4.4

I have a stock SGH-i337 running android 4.4.4 that is rooted.
I've rolled back to NC1 without success. I'm currently at NJ4.
I need to go from AT&T to T-Mobile.
I cannot access the hidden menus to remove the carrier lock.
None of the methods mentioned here seem to work - *#0011#, *#9090#, etc.
Any ideas?

Install safestrap, then flash the mf3 modem. Then try regionlockaway.
Sent from my Nexus 9 using XDA Free mobile app

Did that work? I'm going to be trying this for a phone my daughter bought a couple of days ago. It's an AT&T S4 that she wants to use on Tmobile.
The phone is on 4.4.4 and using I337ucuFNJ4. She used Ebay unlocking service and said they couldn't do it because of money owed on the previous owners account. She gave me the IMEI and it looks clean (as she did check this online and with AT&T before buying).
How can the phone essentially have a clean IMEI if money is still owed on the account? I'll get it from her on Friday and see what I can do.

Ok so I have the s4 rooted with towelroot and flashed the modem back to NJ4. Everything works fine.
Installed busybox then safestrap 3.72 and all of it installed fine. I have SuperSu and did a check root all is fine.
Now do I flash in safestrap the MF3 modem files and install regionlockaway then flash back to NJ4 with Odin? Man I have been searching around for hours to try and get this done. I hate asking for help, but if someone could give a little more detail it would be greatly appreciated. I don't want to brick this thing and was trying to get this down to give it to her in a couple of hours. Thanks guys.

I have a new paper weight.
I've fallen back to my original Galaxy S.
I hope the GS6 arrives soon.

Is unlocking this at&t phone even possible? And what did you do to brick your phone dude? I get the feeling I'm wasting my time with this, that it's not possible and people in the know are having a laugh. I hope that is not the case here.
There is just too much BS on the internet and feel like I'm searching for a needle in a haystack at this point.

Battery failure / short circuit / smoke / bad luck. I have to obtain a battery before I can tell if the damage is permanent.

Got it to work!
Ok I first off sorry for your trouble and hope the phone is not damaged buddy.
I used this technique here http://forum.xda-developers.com/gal...aranteed-free-sim-unlock-mk2-nb1-nc1-t2852979
Odin 3.10 was no longer working for me to flash baseband modem so did it all using safestrap. The files that safestrap uses are zip files and use them like they are (don't unzip them to use) and they are about 22 mb's in size.
The trick for me is it didn't work right away. I had to reflash with safestrap my NJ4 modem and reboot.... and put in the correct APN settings for T-Mobile.
So it does work and hope I can help others that fall into the same problem. If you need help just leave a message in this thread and I've subscribed to it so will get an email letting me know.
APN settings - https://support.t-mobile.com/docs/DOC-17581
This page came in helpful for grabbing need modem/baseband firmware - http://forum.xda-developers.com/showthread.php?t=2496517
Good luck! Do a backup in Safestrap if you're nervous. You can always start over.

The good news - only the battery was burnt.
What boot loader do I have? getprop ro.bootloader returns I337UCUFNJ4 and getprop ro.boot.baseband returns MDM. I presume that MDM is the bootloader version and I337UCUFNJ4 is the modem version.
I'm concerned that the guides and tips are for older versions of the GS4 that don't work on 4.4.4 and may actually do damage.

Ok glad to hear the good news man. The I337UCUFNJ4 is your modem right now.
A nice little free google play store program to use to get info on your phone is called Phone INFO, download it now please.
This will show you all kinds of information on your phone and what you need is to know is Device Type to know which Safestrap to install. Mine or my daughters was klteatt.
Keep in mind I don't have the phone in hand anymore, gave it back to her last night.
What you'll need to download from the modem page link is the I337UCUFNJ4 and the MF3 modems and keep them in their zip format to use. Create a folder on your external sd card ( mine was EXT SD Downloads ) and put both modem zip files in there.
Another program that needs to be installed is called BusyBox and I just used the free version https://play.google.com/store/apps/details?id=stericson.busybox&hl=en
You will need this busybox installed for safestrap to work properly. And also have developer Options activated and check install from unknown sources etc etc (you can do a quick search on this one) it's key to have this done and very quick to do.
Now if you follow the instructions here http://forum.xda-developers.com/gal...aranteed-free-sim-unlock-mk2-nb1-nc1-t2852979
the only thing I did different was flash back the modem MF3 firmware back to the NJ4 that you currently have. APN T-Mobile settings might have auto populated once the card was recognized (I had manually put it in earlier when it didn't work before flashing to NJ4) so not sure.
When safestrap is installed properly it will say so at the top of screen and nothing is greyed out. Do a backup so you can start over if you screw it up. Take like ten minutes or so, no worries.
I've had very little coffee this morning and sorry for being a bit all over the place with this. Let me know how it goes and if you need more help. Good Luck! At least you know it will work, I didn't.
I used Safestrap-JFLTE-3.72-kk-B01 (sorry for confusion forget the klteatt, sorry)------- phone INFO - https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en

I followed the instructions very carefully. The problem is that I no longer have cellular service on any network.
I've rebooted, tried to reflash each of the modems. NJ4 flash fails while the MF3 flash seems to work, but I still have no cellular service.
Phone info shows bootloader NJ4 and baseband MF3

hmmm makes it a bit harder not having the phone with me anymore. You did the developers options correctly?
Perhaps use Play Store and download 'SELinux Mode Changer' to see if it will allow you to install through Safestrap the NJ4 modem firmware?

Thanks! The phone is now working but I have to download, install and configure all (~150) of my apps again.
It will take a couple of days to pair all the Bluetooth devices (plus travel). I wish I'd known that this was a complete reset. I could have captured many of the apps, network locations and configurations. That said, I don't have to buy a new phone.

I appreciate everyone's help!

[GUIDE][ROOT] Sim Unlock S7/S7 Edge

This guide is for those of us that have devices that have been updated to the new bootloader 4 firmware which prevents downgrading to a firmware compatable with most sim unlocking tools. Firmware versions that suffer this include PH7, PJ2 or PK1 for s7 and s7e (s7e=edge for purpose of this guide, s7=g930x, s7e=g935x).
This method was used personally and tested using a sprint s7 g930p on PJ2 firmware. Your mileage may vary
This involves rooting and will trip warranty status flag. If you have another rooting method different from this thread that wont void warranty or trip KNOX please use that instead.
After this guide you can use a unlocking method of your choice a few that work will be outlined later and also a few to avoid. I also recommend having a copy of your stock rom in case anything goes wrong.
Part A: Setup
1.) Download Root_S7.zip from the bottom of this post, extract the files so that you have the folder Root_S7 with files inside it.
Copy this folder to the root of your phones internal storage and leave a copy on your PC also so you can run(double click) Root_S7.bat in the later step.
2.) Download and setup Package Disabler and use it to disable the following: (should be about 5 apps total. This step not 100 percent necessary but I found it made things easier)
Anything that says Knox
Anything DM (all of them)
SecurityLogAgent
3.) Go to Settings>About Device> and tap "Build Number" 7 times to enable "Developer Menu" then enable "USB Debugging" and "OEM unlock" in the Developer Menu.
4.) Power off the phone completely, now hold Home and Volume-(down), keep them pressed and power the phone on.
5.) Press Volume+(up) when prompted to enter "Downloading Mode"
6.) Connect USB and wait for all drivers to finish installing on PC.
7.) Download SM-G930x_Engineering_BOOT.tar.md5 or SM-G935x_Engineering_BOOT.tar.md5 (choose correct file for S7 or S7e).
8.) Open Odin3 (Run as administrator), then select the above file in "AP" slot, then press START on Odin3, the file will be flashed.
9.) keep phone connected to PC as soon as the system identifies the device Double click "Root_S7.bat that is inside Root_S7 folder that you extracted on your PC. After the phone reboots automatically it is rooted. (it may take a couple tries due to the phone bootlooping, once successful SuperSU will be installed)
10.) Open SuperSU app and go to its settings>Access> and change it from "Prompt" to "Grant". After you have changed this setting the phone should only reboot 1 more time.
11.) Proceed to unlocking
NOTE: If SuperSU prompts "update su binary" you need to run the Root_S7.bat again, and/also check that you have copied Root_S7 folder with exact same name and location as the picture below. Do not use the SuperSU from playstore use the one included in the zip.
You can now unlock using idoneapps or you can PM grsjohn.
After unlock I suggest reflashing stock rom to remove root and restore functionality.
Part B: If you decide to pm Mr. grsjohn.
1.) On a windows machine download and install TeamViewer 11 and Usb redirector
2.)In Teamviewer click extras>options>advanced>show advanced>install VPN driver (its close to the bottom)
3.)Contact Mr. grsjohn. Prepare to donate because Mr. grsjohn is awesome and is doing this with his own resources and free time. :fingers-crossed:
Thanks to and beers for
colormedroid For Root Thread here.
grsjohn for sim unlocking. :highfive: And gets my endorsement.
idoneapps for guide and root zip here.
Note: I Bulletbeef am in no way associated with idoneapps.com or any other entity. I was in the situation that this guide addresses and thought it a nice thing if everyone could have the information consolidated and in an easy to follow guide. I WILL NOT BE HELD RESPONSIBLE FOR PHONE BRICKS, LIMBS STUCK IN TOASTERS OR THE DELAY OF HALF LIFE 3.
