Let’s see how to install the Android 4.4 KitKat on your Samsung Galaxy Gio GT-S5660.

WARNING!

Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-S5660! 

Do not use the procedures discussed here on any device of Samsung or any other company. You have been warned!

BEFORE YOU BEGIN..

You must do this pre-installation stuff before attempting to install the ROM on your SAMSUNG GALAXY GIO  in order to avoid any complications later, and have a smooth and successful process.

GET THE LATEST CWM/TWRP RECOVERY

Make sure that you’ve latest version of the recovery of your choice installed on your device.

Older versions of both CWM and TWRP recoveries are not working with Android 4.4 based ROMs, throwing installation errors and WiFi bugs, therefore you need to use the latest version of either recovery.

BACK UP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

ANDROID BACK UP AND RESTORE GUIDE: APPS AND TIPS

CHARGE YOUR DEVICE

If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.

EXAMPLE VIDEO

If you haven’t used a custom recovery, either CWM or TWRP, before, to install a .zip file of a ROM on anything else, then we suggest you first watch a video of that, given right below, to get familiar with the process.

Just fyi, the video below shows installing a .zip file (of recovery) on Galaxy S3, but it doesn’t matter as the process remains exactly same. So, once you are finished with video, jump to downloads and step-by-step guide below.

GUIDE FOR CWM RECOVERY USERS
  1. Boot into recovery mode. For this:
    • Power off your device and wait for 5-10 seconds until the device is fully switched off.
    • Press and hold  Home + Power buttons together and release the power button as soon as you see the Galaxy Gio logo.
    • But hold the Home button until you see the android logo with the box.
      └ In Recovery mode, use Volume buttons to navigate Up and Down between options and use Power button to select an option.
  2. Create a Nandroid Backup from recovery. It’s optional but very important to do, so that in case something goes wrong you can restore to current status easily. For making a Nandroid Backup, go to Backup And Restore » Backup.
  3. Perform a full clean-up of your device (This will delete all apps and their settings and game progress). For this:
    • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot).
    • Enter Mounts and Storage and select Format System.
    • Enter Advanced and select Wipe Dalvik Cache.
  4. Now Install the ROM file:
    • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the ROM file.
