No worry, you can install this XXELKC firmware on any region Galaxy S3 as long as the model is GT-I9300. Personally, I prefer to use custom ROM (just like screenshot above) which based on this official XXELKC firmware. Lot of tweaks and optimizations. But rest assures that official stock firmware is working just fine for most of you…

    Hi Jayce,

    I was using the beta version which came out not so long ago and its working just fine. Seems like most, if not all, of the premium suite is already included in it. Any real reason that you can think of or suggest, for me to make the change from the beta version to this official version.

    Thank you πŸ™‚

    • Official one get to use with Samsung Kies.

  • Hey jayce is this rom has any bugs ?

    • I am using custom ROM based on this firmware. No issue so far. Running great.

    Hello Jayce,,I think you already know about a major vulnerability has been found on devices using Exynos 4SoC and Samsung Kernel sources.I hope you can post that issue on your blog for reminder for all, who is using the device.

    • Thanks for the tips, Jay. Posted a temp solution.

  • Carsley

    This is the official one? After ROM it need to reboot and all the things that i have will still remain?

    • Yes. Official firmware does not delete existing apps and data. But better do a backup for just in case.

  • ivan

    hi jayce,just wanna ask if this is only for custom ROM?

    • No, this is official Samsung firmware. Not custom ROM.

    Hi Jayce πŸ™‚

    I want to update my galaxy s3 gt-I9300 to the 4.1.2 version. I’m going to wait for the official version being released for my country. The only problem is that i have completely removed some bloatware from my Phone and from what I understand I cant update my software because of this. I am rooted with cf 6.4. How do I update my phone to the newest version? Will I have to flash a new stock rom via Odin and then update via Kies or OTA or can I just install it right away via Kies? I cant however update via OTA by now. Says something about my device being changed. Maybe because of the removing and freezing of bloatware?

    Thanks for all help!

    • Hi Tor,

      Did you remove or disable bloatware?

      Use Odin to install latest firmware directly. Rooted device can’t use OTA, need to use Samsung Kies to upgrade firmware.

      • Tor

        I completely removed it. So what you’re saying is that I need to flash it via Odin, I cant update via Kies?

        • You need to use Samsung Kies since your device is rooted.

    hi ya,
    i used your link to do the official upgrade to my sgs3.
    i now have 4.1.2 running BUT
    when i plug in the headphones i get the message “unfortunately, Touchwiz home as stopped working”.
    the phone runs super slow and moves from screen to screen randomly and on its own. when i unplug the earphones everything returns to normal within 15 sec.
    can you help me with this ??

    • Hi steve, try factory reset your phone.

    Okay, Thanks Jayce πŸ™‚

  • Melvin

    Hey Jayce what’s up! This will unroot my S3 right? Can I use the same steps in rooting 4.1.2? I use CF root for ICS and JB last time. What method did you use? CF Auto Root? I kinda afraid after I read some users brick their device. =P

    • Yes. Personally, I did not try this firmware. I am using custom ROM based on it. CF-Auto-Root should work fine.

  • yaw sant

    Hi Jayce, My S3 Model is gt I9300T.Can I install this firmware?

    • Sorry yaw, I have no idea this firmware work on I9300T model or not.

      • yaw sant

        Sounds not good….So sad.I did upgraded 4.1.1…and then my S3 became slower than before.I don’t know why.As usual, my device should become faster than ICS.Seems like I should downgrade to ICS again.Bro, can you please instruct me what should I do.Can you tell me what kind of firmware or Custom Rom I should use to have better performance for my device or should I wait till Samsung release Official firmware4.1.2 for My Model I9300T? Thanks for your reply anyway.

        • I don’t have I9300T. Not sure I9300 ROM can work on I9300T or not.

          Better wait for official Android 4.1.2 firmware for I9300T.
