I was actually going to wait until the official Jelly Bean is released next week for GT-i9300 but I spent the whole day yesterday playing around with the latest leaked Jelly Bean version and added some of my favorite mods like custom boot animation and init.d script support.

Well, I wasn’t going to put this up but since I am running it already (and it seems to run fine, great battery life), you can try it until I put up an official version of the new HighOnAndroid “420” Jelly Bean ROM next week.

Let me know what you think!

    Looks good but i still stick to foxhound rom. I like the functions and jelly bean is running great.

    Hey Max, after I rooted I9300 I backed up STOCK ROM.
    If I restore STOCK ROM will the OTA update be available to download even though still rooted?
    I’ll probably just stick to flashing customs but was just curious.
    Thanks bud.

    Hey Max,

    How are now days? I want to say that you are doing a great job, just perfect, thank you soooo much πŸ™‚
    Now, I just installed the 420 jelly bean ROM, and i must say that itΒ΄s smooth as butter. The only thing is the bug on the lock screen. Any advice?

    Hi Max,

    As usual great work. I have an issue with the lockscreen as well. It’s not that major an I could live with it. However I switched back to my previous rom because this one seemed to be eating up the data. When I checked what apps were connecting, the gallery used up about 500mbs in an hour. I’m not sure if it is just some setting I have. So maybe you you can check that out.

  9. Francis says:

    Hello everybody

    i solved the lock screen bug by doing this:

    Settings—>lock screen, and then uncheck “swipe to unlock”.
    This worked for me.

    Hi Max,

    I have a problem with the S Memo and SNotes after installing the ROM. When I’m trying to use the old S Memo information is displayed that S Memo has been discontinued and I’ll be transferred to NotesS.
    The NotesS application do open but there is a grey stripe across the screen with the information that this model GTI9300 is not supported. The script stops at target name: ANDROID_FULL_JAVA model not supported in the attached library.
    Will this problem be solved with the official JB?
