For this week, check out Ultima Jelly Bean ROM for your Galaxy S3 GT-i9300.

Based off latest XXDLJ5 Android 4.1.1 Jelly Bean base, the Ultima ROM brings the best of Jelly Bean and a TON of customizations through its AROMA installer. Some notable features include ability to choose 4-5 different kernels, multiple camera options (Galaxy S3 camera, HyperMOD camera, Galaxy Note 2 Camera, Android 4.2 Photo Sphere Camera), and highly “blue” themed ROM.

I think this is one of the better “hybrid” ROMs I’ve seen in awhile and comes with a ton of new things you will appreciate like Nexus 4 wallpapers, 52 ICS blue wallpapers, etc..etc..

Also the AROMA installer is probably the best right now in terms of level of customization you can do on this ROM.

So, give it a go and let me know what you think!

    Very cool rom!

    Do you have a link for the wallpaper, it’s not showing up.

    Would be AWESOME to install all the different cameras at once. I but the 4.2 is awesome :-)

    Very good and reliable rom. All the apps are working ok. No problems so far. Blazing fast very customizable and at the same time I have all the Samsung apps available and working.

  9. Ralph says:

    when you install a new ROM automatically it’s erased the last ROM that had the phone?

    my question it’s just to know about the memory.


  10. Rick says:

    Hi Max,
    I reinstalled the Polish Jelly Bean Rom, you uploaded. Started to like it. :-)
    Can I flash to this Ultima ROM the same way, just doing it after a full wipe?
    Nothing to do extra?
    Thanks in advance,

    • Kevin says:

      Search this on google:
      Download Google gapps jelly bean

      Move the zip to your phone or SD.
      Boot into CWM recovery, choose install from zip.

      Wupti, and then it’s working.
      I had the same problem and I just found out yesterday :-)

    Hi Max

    I was looking at the Ultima Rom_v5.0.2. While your website states the file size to be 964 MB and that’s what the download starts at, the Actual Downloaded file is only 248 MB. I have tried multiple downloads but still the same.

    Am I doing something wrong? Shall I install the Rom downloaded?

  14. Robert says:

    Can someone please tell me what ROM i can install on my ATT gs3 (sgh i747) that works completely? Seems like every time i see one i like something in it doesn’t work or its not for ATT models. Something a little faster, smoother, with a few more tweaks would be nice. Thanks

    Hi Max and folks,
    For some reason my download for this ROM is stuck on 92% complete (887.54MB of 964.33MB).
    It’s not downloading any more at all. My internet is working file and I’ve downloaded another file just to check.
    I really would prefer not to have to start all over again. Never had this problem with downloading your ROMS before.
    Any suggestions?

  16. mike says:

  17. Xafiq says:


    Do I need to reflash the phone just to gain access to the Aroma Installer again?
