Update Galaxy Gio S5660 to Android 4.2.2 JB with CM10.1 Custom ROM Firmware

If you own a mid-range Android based smartphone that can’t be updated with official Android 4.2, or 4.3 Jelly Bean platforms, then you have to get a suitable custom ROM software that can still bring the latest features, apps and capabilities to your phone. As you know the Galaxy Gio is stuck on Gingerbread OS due to hardware limitations; anyway, you can still update your handset as there are numerous custom ROMs available out there. But today, I will show you how to flash one of the most popular and used custom update on your Gio, the Android 4.2.2 Jelly Bean based CM10.1 firmware.

So, you are not only flashing Android 4.2 JB on your Samsung Galaxy Gio S5660, but you are also applying the best Android powered custom ROM available out there. CM10.1 is a stable software that comes with great features and capabilities that can be used for bumping the speeds of your smartphone, for upgrading the battery life and for improving the performances of your device. Once CM10.1 will be installed on your Galaxy Gio you will be able to experience a handset that runs on a higher level of power, so you will be enjoying an updated web browsing experience and a customizable version of Jelly Bean 4.2.2.

CM10.1 is not an official Android 4.2.2 Jelly Bean update that has been released for your Galaxy Gio. The software has been developed by third party devs and represents a free aftermarket distribution of JB 4.2.2. CM10.1 brings stock and extra features along with a custom user interface so don’t expect to update your Samsung Galaxy Gio with the default variant of Jelly Bean OS. Furthermore, since we are not dealing with an official update, CM10.1 can be installed only if you first complete the steps from below.

  • Root your smartphone for removing the factory restrictions; CM10.1 will need access to the internal system and this access can be granted only by rooting your phone.
  • After completing the root procedure, install CWM recovery or any other custom recovery for Android on your Galaxy Gio. The custom ROM will be flashed via CWM recovery, so don’t skip this step.
  • Backup the data that is saved on the internal storage memory of your device. A wipe will be required so all of your personal info and saves will be lost. So, first complete a full backup – for saving contacts, messages, call logs, EFS folder, internet settings, market apps and so on; also use CWM recovery and make a Nandroid backup.

By gaining root access the warranty gets void. Don’t panic as you can restore it by downgrading your phone to stock Android OS. Now, root is extremely important this being the first step to complete when trying to improve the performances of your Galaxy Gio. Besides flashing a custom ROM, on rooted systems you can also install custom kernels, overclock the CPU, install apps that require root access in order to properly work and so on. Also, the custom recovery is quite important as by using the same you can perform operations like: installing .zip files from SD card, apply backups, restore the system, maintenance, optimize and customize the OS and lot more.

Now, for the present tutorial you will need to have access to a computer on which first you have to deactivate the security protection because the antivirus tools might interfere with the update operation. Furthermore, your Galaxy Gio must be charged; plug in the charger if the battery status indicates less than 60% power left (if you phone gets turned off while you are completing the steps from below, you can end up in bricking your Gio). Enable USB debugging option on your handset from here “settings -> applications -> development -> usb debugging” – do this if you want to safely connect your device with the computer.

Apply this guide for flashing CM10.1 Android 4.2.2 Jelly Bean OS only on the Galaxy Gio model number S5660 because the steps from below are compatible only with the mentioned smartphone. Else you will risk in bricking your Android based device.
