    Wypasiony ROM-ik ale poczekam na aktualizację 4.0.4 do RC4 No chyba że rozwiniecie 4.2.1. Miałem taką wersje 4.2.1 i CM 10.1
    ale telefon mocno lagował i musiałem robić reboot 2x dziennie.

  • Hmm to obtain root you can always use Bin4ry’s root method 🙂 Tested working on my Gio!
    Thanks a lot Maclaw and team for this release!

  • Thierry says:

    Hi, how to find Bin4ry’s root method for Gio

  • Thierry says:

    Thanks Kevin I will try your solution.

  • Thierry says:

    Kevin, Installation work as you say but does not work when titanium backup ask to get root rights with command /system/bin/su.
    thank you anyway.

  • Tri says:

    Thierry! choose option 1 at binary root method command prompt, you will get restore option at your phone and restore it then quickly manually reboot your phone but dont close bin4ry command prompt. SU binary will installed when phone rebooting. Titanium back up, Link2sd, busybox installer is work well for me…

  • Marvin says:

    Thanks 😉 can you fix the camera please… 🙂

  • Harsh says:

    Will this rom work on s5830i ?

  • rohit says:

    none of your realese is stable … bugs are still there ..

  • Alex says:

    Hello, i have a Galaxy ACE and it has very low space in the internal memory. Is there any way for you to send the “Play Store” and the “Google Services” (i think is part of the store) in APK format so we can install it and then move it to the SD with “Force2SD” ? Because they consume lot of internal memory. Thanks for all your effort ! Keep it going !!

    • Tri says:

      I use Link2sd to do that…I have 114 App and still have 108 MB free internal memory for me that`s quite enough.

  • Paul says:

    Could you make a Firefox OS build for Samsung Galaxy Ace?
