Samsung S4 i337 , Official Lollipop

Hello everyone, if for some reason you can’t or won’t update your at&t galaxy s4 OTA ( over the air ), and also at&t doesn't let you update through Kies. So you are in the right place. i’m going to show you another way of doing it, In this thread I'll show you how to manually update at&t galaxy s4 sgh-i337 to lollipop(5.0.1). First, if your android version is 4.4.4 you can directly update to 5.0.1, but if your android version is 4.4.2 first you must update to 4.4.4 after that to 5.0.1, and if your android version is 4.2.2/4.3 you need flash stock 4.4.2 first.

4.2.2/4.3--by odin-->4.4.2--by ota-->4.4.4 then 5.0.1

-Please read the following, carefully and thoroughly.
- All roms below are confirmed working, but flash at your own risk.
-I have tried it on unlocked sgh-i337 and it is worked fine, these packages were not tested on locked at&t Galaxy S4.
-these methods are official, and your system status will still be official.
-All your data on phone will be erased, So before you get started, it's a good idea to back up your data!

First, one of the things that may need to be done is to update your device drivers. You can do this one of two ways.
-You can search the net for your updated drivers. Download and then install to your PC.
-Or you can download or update Kies.
Once drivers are installed, a restart of your PC may be required.
Second, don't forget to enable USB debugging. In Settings> More tab> Developer options.

Notes:

1-if you get any error in updating to lollipop. First flash stock 4.4.2 even if you already have 4.4.2/4.4.4
2- you can't change file extension in mobile. You need to use a PC. if you can't change/see file extension in PC try these methods :
-Displaying the File Extension in Windows Vista and Windows 7/8

Method-1


1. Click the Start menu. ...
2. Type "folder options" (without the quotes). ...
3. A dialog box with the title "Folder Options" will appear. ...
4. Click to uncheck the box for "Hide extensions for known file types".
5. Click the "OK" button at the bottom of the dialog box.

Method-2


1. Launch Control Panel. In Windows 8 / 8.1, you can get by hitting Windows + X and selecting from the menu that appears.

2. Open Folder Options. If you don't see the Folder Options icon right away, you can find it by typing Folder Options into the search box at the upper right corner of the control panel window.

3. Select the View tab.

4. Toggle "Hide extensions for known file types" to off. I also recommend changing Hiden files and folders to "Show hidden files, folders and drives" so you can access all of Windows' system folders.

5. Click Ok. Now, any time you browse your file system, you will see all file extensions.


-Displaying the File Extension in Mac OS X
