[Q] Help with issue - bootloader not unlocked for Galaxy S4 (SGH - I337) . - General Questions and Answers

Hi,
I have a Samsung Galaxy S4 (SGH - I337) for AT&T (unlocked). I wanted to install the 4.3 google edition software on my phone.
Every time I boot the phone, I get the error, "System software not authorized by AT&T has been found".
I have been at this for hours and hours, reading this forum, searching, google, and cannot find a solution.
Basically the only thing I can do is get to TWRP v2.6.0.0 when I first start the phone, or read the error message above.
I would like to find out how/what I would need to do to get passed this error and start using 4.3 google edition, or revert my phone back to its original state.
PLEASE any help is very very much appreciated!!

[Completed] [Q] Updating Rooted S4 from 4.2.2 to 4.4.2

Hello XDAdevelopers
I am out of patients with the internet, I searched all over including this forum but found nothing that helped me (possible I saw the help I needed but was unsure if it pertained to me).
The situation I am faced with is that I recently bought a Samsung Galaxy S4, I opted for an international version (because of where I live). When I unboxed it to my surprise it came rooted (it is brand new fyi). Immediately after turning it on I saw that there was an update out for it, tried to get the update but I end up with a message saying (after saying registering device for 5 seconds) "Attention Processing Failed". I have combed through the forums to come to the conclusion that I can't update my device because it is rooted. I have tried to unroot my device though SuperSU and factory reset, but when I do this the device boots into the OS with rooted access.
So my question is how can I update my device to the official 4.4.2 (which at the moment is latest to my knowledge if there is a later version I would like to go to that instead). I don't mind losing any data and also I would like to re-root when I install 4.4.2 (given that after the process it is not rooted). Is there a way to go from rooted 4.2.2 to rooted 4.4.2?
Important information:
Model Number - GT-I9500
Android Version - 4.2.2 (stock rooted)
Baseband Version - I9500XXUAMDK
Build Number - JDQ39.F3A268.2JIA388 (That is what I see)
In status->Device status it says Custom
I do not live in America
Also if I need to install mods and other programs to my phone (or computer) please indicate because I am new to rooting Samsung devices. Lastly, think thing called cyanogen, I see that there are some very useful tools with it, would the end result of the procedure allow me to install this mod?
If more information is need, asked and I will provide it.
Hi,
You can likely install 4.4.2 manually with Odin. See this guide on that. You can also ask for help in this thread

Good luck!
Thank you. Thread closed.

[Completed] [Q] After boot and samsung logo black screen. S3 SGH-I747M Kodoo Canada

I'm out of Ideas, please help me.
Here is my info:
Samsung galaxy s3 sgh-i747m from kodoo Canada. I had installed cyanogenmod through their installer over a year ago. I have been using it with my rogers sim with no problems. Less than 2 weeks ago my screen randomly goes black. I try pulling the battery. The samsung logo appears but then back to black but I can hear everything is working. I Try and boot into recovery and everything is black. I boot into download mode and everything looks fine. I try reinstalling cyanogenmod and then Samsung stock through kies and smart switch and every stock kodoo file I can find .
There is one of two things that happen.
If I install a stock below 4.4.2 I get fail in Odin 3.07 and this on download mode:
Odin Mode
Product Name: SGH-I747M
Current Binary: Samsung Official
System Status: Official
Qualcomm secureboot: Enable
Warranty Bit: 1
Bootloader AP SWREV: 2
SW REV Check Fail : Fused 2 Binary 1
If I install a stock rom with 4.4.2 or install from Smart Switch
Everything proceeds perfectly but upon reset I see the samsung logo and then nothing just a black screen with the chime in the background. Still can't boot into recovery. I only see the recovery in blue in the upper left corner but then nothing.
I would greatly appreciate any help you can give me.

Good luck
Thanks for the reply R_a_z_v_a_n.
The [HOW TO GUIDE] How To Unbrick AT&T I747 and I747M After 4.3 OTA states from the beggining: thus far this method will not work for any of your 4.4.2 ota bricks if you flashed the 4.4.2 modem on the mjb bootloader, the only way to fix those bricks is with a new emmc, motherboard or a new phone. Jtag won't save you this time the phone is now a glorious paperweight.
I believe I'm on 4.4.2. because those are the only roms I am able to successfully install but then of course the screen goes black. So if that is the case, does it mean my phone is done? just a paperweight as the article says?
I'm wondering if I should try anyways or is there a sure way to get my phone running from 4.4.2.?
Thanks for the help, look forward to your answer.

[Completed] Galaxy Note 3- Unroot android 5.1.1?

Unroot Note 3 android 5.1.1
Hello, I recently was given a rooted T-mobile Note 3. The guy who gave it to me, tried either updating or wiping it and it got stuck in a boot loop. I was able to get it out by simply putting it into download mode and taking it out. But then it has a never-ending "unfortunately google app has stopped" error. But it works if I create a new profile; google play doesn't work though.
So anyways, I need to unroot it so I can activate it. The android version is 5.1.1 the only version I can find is 5.0 I read that downgrading when unrooting will trip some anti-root switch: However I couldn't find anything saying if this would happen going from 5.1.1 to 5.0.
Any help is appreciated. thanks.
