    Nice article. This Galaxy Gio S5660 Samsung Android phone is a low-end smartphone that was not updated at Android 2.3.6 official firmware. But, you should back up your data first before start upgrading.

    I followed the steps and I’ve installed the xxktu android 2.3.6 firmware but now I can’t root it! I applied several files which I found on the web but none of them worked.

    Is there a special root file for XXKTU android 2.3.6 firmware???

    Thank u in advance!!!

      Root is actually exploiting existing firmware security. It look like Samsung fixed previous exploit, hence you need to wait for newer method. We didn’t come across any specific method for this firmware for now.

        Thank u for the answer, I gues I’ll have to wait for a new rooting method, I hope that I’ll find an app which can move installed apps on the sd card whithout the need of rooting, because this was the reason I wanted to root my phone .It’s a great firmware and I thank u for posting it! Cheers and good luck!
