Even if according to Samsung, there won’t be any future official updates released for the Galaxy Gio S5660 handsets, you can still improve its OS by applying a custom ROM firmware. Last time when we talked about the Gio, you were able to flash the CyanogenMod 9 software into its system, which brought the Ice Cream Sandwich OS on your smartphone. Now, I will teach you how to update the Galaxy Gio to the latest Android platform, Jelly Bean 4.1, by installing the CM 10 custom ROM on it. The procedure will be similar with the one explained for the CM9 firmware, so you have nothing to worry about.
Because this is not an official update, you can’t OTA receive it. You must complete a manual operation for being able to flash the same on your phone. That’s exactly what you can learn during the present step by step guide, all being explained and detailed so everybody can understand what and how to do it. Also, for being able to flash the Jelly Bean based CyanogenMod 10 ROM you will have to previously root the phone and install a custom recovery image on it. You cannot complete the below steps without performing these tasks.
For rooting you must follow a suitable guide for your handset and also you should be aware as the warranty will be void. Read carefully before adventuring in changing something on your device as you can easily brick it. For the future, if you will want to regain the lost warranty, you will be able to do so, but only by downgrading to the stock ROM or by updating with an official software provided by Samsung for your Gio (not for similar Android powered smartphones). Then, the recovery image will be used for installing the CM 10 file on your phone, so getting the same isn’t an option for you.
As for the firmware you are about to get for your device, you should know that it’s still in beta stage, so there might be some bugs in the system. Don’t worry though as the issues will be removed as soon as the CM team will provide the proper ROM. Now, this version of the update was developed and tested for the Galaxy Gio by those of xda-developers (we have them to thanks for the present guide) and according to them there are some problems with the camera and with the proximity feature. But for making a better view of the software here are the things that do work:
On the other hand, a backup must be completed before applying this tutorial. The data might get corrupted so you will no longer be able to use the same. Also, there are some pre requisites that must be performed, or else you will not be able to update your Galaxy Gio. I have summarized during the next list some backup tips along with the preparation operations, so check and complete the same.
- Learn how to backup and then restore the current ROM in case you manage to damage it while trying to update your smartphone.
- Download SMS backup and restore tools for saving the text messages.
- Download Call log backup and restore apps for Android.
- Save the contacts by syncing with your Gmail account.
- Use a computer or SD card for saving other files.
- Remember to root and install a custom recovery image.
- Then, enable the USB debugging option from here: “Settings -> Applications -> Development -> USB debugging”.
- Also, on both your computer and phone uninstall or deactivate the security programs like antivirus or Firewall protection.
In the end make sure that your device has enough battery life for the process (at least 70%) or else charge its battery.
Now, don’t perform the below steps of you own a similar device with the Samsung Galaxy Gio model number S5660 because you can brick it. Just stick to my directions, don’t apply thing by yourselves and everything should be just fine. So, let’s get started.
