We have long known that the Samsung Galaxy ACE S5830 will not receive the official update to Android Ice Cream Sandwich, so that the firmware of Android Gingerbread will be the last we see.

In this case it is the ROM XWKTQ based on Android 2.3.6 Gingerbread which we assume includes some fixes and improvements over the previous version called XWKTM.

Previous requirements:

  • All data such as contacts, SMS, photos, music and videos will be deleted if they are stored in your phone. Please do not do a backup of the data with KIES as it creates the backup in the format (. SBU)  that sometimes has problems in the restoration or does not recognize the phone. Therefore, is strictly recommended that the backup contacts as well as the SMS is performed by following the steps below:
    • SMS – Use SMS Backup y app Restoration
    • Contacts – Sync with Gmail application
    • Songs, videos, files – Copy to SD card
    • Take note of APN and MMS settings in Applications> Settings> Wireless & Networks> Mobile Networks> APN
  • Make sure that all security solutions like firewalls, antivirus and KIES application are completely closed until firmware update finishes.
  • It is very important to make sure you have ADMIN privileges before proceeding to update the phone and the USB port must be open which means you must have read / write so that the firmware can be applied successfully.
  • Note that you will need to charge your phone at least 90% battery to ensure that does not interrupt the update.
  • Never interrupt the firmware update manually, just in case, if interrupted by power failure there is no need to worry because all you have to do is follow the instructions from the beginning.
  • Whatever firmware you currently using, if you have root access you will lose it because it´s an official firmware.
