    Neal, I followed your instructions to updating my Samsung Galaxy S GT I9000 to install Ice Cream Sandwich Android 4.0 Alpha Firmware and now, I think I’m dead. Cos I’m not a developer, and I thought it was for normal users and followed the steps…
    Now I’m paralyzed. My phone does nothing, I can’t even unlock the screen. USB debugging seems impossible. Major S.O.S!

    Please help!!!!

    Thank you!

  22. I did all you ask and there is no single change to my phone even checked about phone it still say Gingerbread 2.3.5

  23. Can you please upload the latest version in which xda developer managed to get the touch screen and sd card working. I think he got 2g and 3g also got working.

    Please include detailed instructions to upload page.

    Can i update to ice cream sandwitch from xxjvr as xxjvt is buggy and the wifi keeps disconnecting?

    Appreciate your good work.


  24. hey neal. had serios problems trying to update from 2.2 to 2.3.5 gingerbread through samsung kies and was trying for a few months but came here and ur guide helped me straight away and got it so i trust your advice. When is there going to be an update for 4.0 ice cream sandwhich.

  25. very useful forum.

  26. Tq neal,i flash back to XXJVS b’cos it’s more faster then XXJVT so by using XXjvs can update to
    ics 5.1 rom or any better.

  27. these firmwares do not apply to galaxy plus i9001 right?

  28. ok,
    I’m a bit new to this and had this query about the naming conventions of the firmwares like XXJVP / XXJVQ / XXJVR etc. Could someone explain me what exactly is this naming convention and who are producing these firmwares. And how many firmwares are there for galaxy S GT I 9000. I mean besides the samsung’s own current 2.2. 2.3.2 versions.

  43. Hey NeaL,

    I installed it correctly, but after first boot it stuck in Lock Screen and it doesn’t work, i can’t go inside.
    I already cleared the cache and wipe.

    and i have xxjvt, rooted.

  44. Neal
    what does this mean?
    Lock screen, touch screen sensors and the correct screen resolution are the only things which are working in this Port. No application works but the back key as well as the menu key works.
