For those who still runs or used the official Android 4.2.2 M919UVUAMDL, the M919UVUEMK2 4.3 update is now officially rolled-out and you can simply upgrade via OTA (over-the-air) and or Samsung Kies server.

Important Notes:

The Android 4.3 Software Update build M919UVUEMK2 is now equipped with new Bootloader and the implementation of KNOX security suite. Once your phone updated to 4.3, there is no way you can downgrade back to the old software like the 4.2.2 M919UVUAMDL. There is now a KNOX Warranty void counter which you may find it hidden in download mode option. By pressing Volume Down+Home+Power button it shows you the “KNOX Warranty Void: 0×0″.

Now, flashing any unsigned or unofficial firmware like custom recovery, root kernels will result into ripping the KNOX Warranty red-flag counter. Once tripped it will then turns your system to “KNOX Warranty Void: 0×1″. Meaning, your warranty is already compromised and there is no way you can revert it back to normal and no other working method to reset it back.

Can I only flashed only just the MK2 modem? 
If you have custom ROM and only wants to install the new M919UVUEMK2 MODEM or might probably you already installed it, well this time it will not worked anymore, since the Modem is also protected with the new 4.3 bootloader, and once you only install the Modem, you will only going to faced issues like WiFi data signal lost and can’t even make any phone calls. So the only convenient way is to flashed the full stock firmware to make it working.

Can I still Root the MK2 4.3 update?
Yes, Root will still worked but keep in mind, from here your warranty will be gone for good. You have no right to bother your service provider anymore once you messed-up then you are at your own.

Will this trip the KNOX warranty void flag once flashed?
No, this will not tripped the KNOX security platform for this the official firmware pulled from Samsung server and officially signed by Samsung and the same firmware files rolled out on OTA. You only tripped KNOX counter if you are going to install any unofficial firmwares, including custom ROMS, recovery, root kernels and any unsigned system images.

Now, click on the AP button, then select and load the tar file that you have previously extracted. “M919UVUEMK2_M919TMBEMK2_M919UVUEMK2_HOME.tar.md5″

Step 6: Connect the Phone to the Computer or Laptop
Once the phone screen shows in downloading mode, connect your phone to the PC with the USB cable. You’ll then notice the upper box in Odin that turns in yellow color., it also indicates the COM:ID where the device is being detected and a word “added!!’ on the log box. If somehow those things never showed up, check out the USB cable connection, read again from the top of this post.
Step 7: Flash it!
Once all set and ready, hit he “START” button to begin flashing.
Do not touch anything that might interrupt the process to avoid any fatal errors or failures, it may ruin your device if any interruption occurs while already in flashing status.

It may takes a couple of minutes or longer and it depends of your PC/laptop speeds. A word “PASS” will display in Odin once it finishes. If somehow you will not get the word “PASS” or just stuck in along time. Disconnect the phone, remove battery, re-insert it, check the USB connection, re-install the driver, disable Kies and any anti-virus. Set the phone in Download mode again, and repeat the whole procedure.

The phone will just automatically reboots if the firmware flashing successfully completes. Just wait until it boots up on the “Samsung” logo for a while then into an android update screen. If it still shows boot logo try rebooting and if it stays there, you need to wipe your phone.

Fixing possible issues after flashing like bootloops or just stuck on a welcome screen logo.
Reboot in recovery mode – Press and hold Volume Up, Home and Power button. Use volume keys to select up and down and power or home key to select the option.
1. Select Wipe Data/Factory Reset
