The Samsung Galaxy Gio GT-S5660 finally gets the royal treatment as the device finally gets a taste of Ice Cream Sandwich (ICS), courtesy of the GalaxyICS Project and CyanogenMod 9.

If you already have tried other ICS-based ROMs then you might want to give the GalaxyICS  ROM a try, as it is perfectly tailored for the Galaxy Gio.The GalaxyICS ROM is an interesting ROM that takes the Ice Cream Sandwich to the next level.

The ROM is currently under heavy development with many features not functioning well. So far, the developers have already made huge progress with the ROM.  The only major issue concerns Wi-Fi, but the developers have provided a patch to work around the issue.

Working features in the GalaxyICS ROM for the Samsung Galaxy Gio GT-S5660:

  • boot
  • GSM (phone/messages/GPRS/EDGE/3G)
  • Wifi
  • Bluetooth
  • HW acceleration (full)
  • Sound
  • Headphones
  • GPS
  • All sensors (proximity, roration etc)
  • CyanogenMod settings (not all, it’s not fully merged by CyanogenMod team, not my fault)
  • Market (now you can download all apps available for Gio with GB)
  • Fixed animations (now it looks so good)
  • Facebook sync
  • Buttons backlight
  • BLN support
  • GMail fully works
  • Browser fully works
  • ICS keyboard
  • Games – works as smoothly as on Gingerbread
  • YouTube
  • Camera – only photos, without preview
  • Deep sleep
  • Wifi signal indicator
  • Native Android mass storage
  • Without flickering

      • RedBoy

        Just restore your backup gingerbread before. Did you have a backup?

      • Andre

        go back to Gingerbread using Odin, (the phone will keep restarting) then take out the battery – then put it back (just to stop it) press the home button (the middle button between menu and back soft buttons) and keep it pressed then press power button.
        The recovery menu will turn up eventually, and from there chose the two wipe options (wipe cache and the other is wipe data/factory reset)
        if asked yes or no scroll to yes then press enter
        volume up down = up down scroll
        home = enter

        restart -> all done
