Android 4.1.2 Jelly Bean XXELKC Firmware for Samsung Galaxy S3

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…

  1. 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™‚

  2. 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.

  3. 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!

  4. 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 ??

  5. 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

      • 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.
