The developers of Android have taken their OS to such a level that in today’s world there is no one who dares to compete with them. One after another many of their new Android versions are releasing and ruling the entire market. From Android 1.5 Cup cake to the recently launched Android 4.4 KitKat, there has been a tremendous change in the performance, specs and many other aspects. From the day the new Android 4.4 KitKat is released, everyone is talking about this new firmware. But due to its much high hardware and RAM compatibility it is only available for flagship devices. The rest users need to rely on those ROMs so as to experience the same. A week ago, it was announced that this latest version is going to get available for mid range devices like Galaxy Ace, Fit, Mini and Gio. In this article we are going to discuss about the detailed procedure for updating Samsung Galaxy Gio S5660 to Android 4.4 KitKat through Cyanogenmod 11.

Samsung Galaxy Gio S5660 launched back in 2011 was a low budget device and had descent specs and features. That’s the reason it was not able to attract many users. It had Android 2.2 Froyo which was later upgraded to 2.3 Gingerbread, a 3.2 MP auto-focus camera, 16m color screen and was sold at the price of $160. The Gio users had no hope regarding the further official firmware releases for this device. But it was the third party Android developers who took keen interest in this device and with much hard work launched the next Android versions of course unofficially.

The much well known Cyanogenmod team took the initiative and launched their latest Cyanogenmod 11 ROM for S5660 users. So its now possible for the Gio users to enjoy and experience all those latest KitKat flavored features like refurnished Google home with new launcher, new phone dialer app, screen recording, security and system improvements, NFC emulation, Google wallet, new quick office, low memory management support, new gallery, battery saving tweaks, new keyboard and much more on your device. Along with that you’ll also be able to enjoy the Cyanogenmod features, thus having a dual features experience.

For the advanced Android users who have a complete knowledge regarding this stuff and have gone through it before are free to proceed further. But the newbies, who are completely un-aware must stop right at this point. If in case your Galaxy Gio gets damaged or bricked by following this article then neither we nor the developers will be held liable for that. Even though the chances that your device will get damaged is least, but still I highly recommend you to follow all that is given below properly and without attempting anything by your own. Also you must note that this Android 4.4 KitKat ROM is only compatible for Samsung Galaxy Gio having the model number GT-S5660. Installing this on any other device or variant will result into unwanted outcomes or bricked device. So you must verify your device model number with the number given above from Homescreen–> Menu–>Settings –> About Phone.

Pre-Requisites:

  • A proper battery backup is must before performing any flashing process. Lack of battery may increase the risk of interruption in the flashing process thus leading to further problems. So I highly recommend to charge the battery of your phone at least up to 80%.
  • Using USB cable connect your Galaxy Gio to PC, enable USB debugging mode and take a backup of your entire SD card. Along with that you must also backup your contacts, messages, apn settings, call logs etc for safety. All these precautions are need to be taken as disaster can knock your door anytime without giving a sign. Also the last step of this flashing process involves wiping all your data and cache from your phones internal memory. That’s why a backup is must.
  • Make sure that Samsung device drivers are installed on your PC so as to recognize your device when connected to PC. You can install them by installing Kies or  manually install them from the link given below:
  1. Download latest Samsung USB Drivers.
  • EFS folder present in your system directory must be backed up. This sensitive folder contains all your phones specific information such as the IMEI, wireless devices MAC addresses, product code, and much more. If by mistake the data in it gets wiped, then this will make your phone completely useless & will no longer be recognized by your carrier. Refer our article to backup and restore EFS/IMEI data:

  • Make sure that your Galaxy Gio is rooted. If not, then follow our guide given below to do so.

  • (IMPORTANT!) For flashing Android 4.4 KitKat you need to have the latest Custom recovery like 6.0.4.7 installed on your Galaxy Gio. If you haven’t installed it yet, then don’t worry just follow this steps given below:

Step 1: Download the latest CWM 6.0.4.7 recovery package from Here.
