How to install / update CM9 Ice Cream Sandwich 4.0.3 Nightly Build on Galaxy Ace S5830 smartphone:

  1.  Download the CM9 Android 4.0.3 ICS ROM zip file from here. Click on Releases and on the opened page click the 'download' button. Wait for the download to be completed.
  2.  Move the ROM's zip file on your phone's internal SDcard. Do not extract its contents, simply leave it as it is.
  3. Power Off the phone and then enter CWM recovery boot mode.
  4. CWM Recovery can be entered by pressing and holding the Home Center and Power ON buttons. Wait for the recovery mode to be loaded. In case recovery doesn't boot then you should retry until you manage to load it.
  5. When in recovery you will need to select the option called 'wipe data/ factory reset' option and then confirm its actions.
  6. Now, select 'install zip from sdcard' and from the new recovery menu you need to select 'choose zip from internal sdcard'.
  7. Use the volume keys to navigate and find the CM9 4.0.3 ICS ROM zip file for installation. Confirm that you wish to flash this new ROM and then wait until the updating process is finished.
  8. After the update is complete, you need to select '++Go Back++' and then 'reboot system now'. Wait for your device to complete the first boot into the new CM9 based home screen. In case the first boot takes way too long to load, then it means that the files weren't successfully applied and you will then need to repeat all the steps above.
  9. If the Android 4.0.3 ICS home screen loads it means that you have managed to update your Galaxy Ace S5830 device successfully and that should do it. Now you're free to restore all your applications and all other files you've saved before installing the new ROM.

Holas, todo iba bien cuando le instale el ROM, muy rapido, con una interface muy bonita, pero, despues de un rato me mostro el mensaje,

"Lamentablemente, la aplicación Trebuchet se detuvo"

y ya de ahí no sale, le pongo aceptar y lo vuelve a mostrar. Una Lastima, tendre que esperar a una versión más nueva.
