Install Android 2.3.6 XXMI1 Official Firmware on Galaxy Y GT-S5360

December saw the release of new firmware to help update Galaxy Y GT-S5360 to Android 2.3.6. This tool will be introduced today and you will find out how to install it on your handset.

But first, let’s see what name this new firmware has: XXMI1. If you live in the countries where this update is available and you want the Android 2.3.6 on your phone, this guide is what you need. Please use it only on the Galaxy Y; if you use the wrong model, you will brick it.

There are several ways to get an upgrade. You can, apart from this tutorial, use Samsung’s KIES (make sure there’s a stock ROM on the smartphone). Especially since the new official firmware comes with an activated KIES logo.

The novelties

After the update is performed and the new firmware is on the handset, you will enjoy things like enhanced data throughput performance in environments that register low 4G signals, superior stability for data connectivity when you want to turn Airplane Mode off, Vcast apps, superior battery life in case you want to use Phone Book Access Profile Bluetooth headsets.

The update comes with a much-needed improvement to VZ Navigator (which is going to include all the latest 3D map enhancements), Visual Voice Mail updates, superior stability while moving between home screen panels, mobile hotspot bug fixes and better security, an updated Favorite Contacts widget, CMAS (short for Commercial Mobile Alert Service) and you will be able to see how much time there is left till you’re ready with the performing of an OTA update.

In the case of a rooted Galaxy Y S5360, the upgrade is going to mess up with your device, in the sense that root access will be revoked. Also, the system partition will be erased, but the internal/external SD cards and important data will not be damaged.Samsung-Galaxy-Y-GT-S5360


Let’s get on to the following requirements:

Important instructions

  1. Now’s the time to show you how the first step of our guide should happen: after you find Odin tool on this page and (you must access the previous link then you must search for the “XXMI1” in the field labelled “Select your firmware”), download them on your laptop and use WinRar or WinZip to extract them.
  2. Then boot the handset in Download Mode by pressing and holding, at the same time, these keys: Volume Down, Home and Power. The Odin will then have to be opened as Admin on your notebook and, when done with this, be sure to establish a connection between the Galaxy Y GT-S5360 and the laptop with the former’s USB cord.
  3. You should be greeted by a yellow ID:COM box and an “Added!!” message. If the connection hasn’t been established, you have to either use another USB port or re-install, on your laptop, those USB drivers.
  4. But if there’s no need for something like that, you can continue by doing this: tap a file that has BL in the name, clicking on AP, opting for a file with AP in the name, tapping CP, choosing a file with CP in its name, tapping CSC, opting for a file which has CSC in the name, tapping PIT and after that choosing a file with an extension which has .pit in it.
  5. After this, you need to activate these couple of boxes: Re-partition, F. Reset Time and Auto Reboot. Once the tasks from before are all completed, you have to begin the actual flashing of the new firmware by clicking on “Start“.
  6. The installation will then commence, so have patience till you see it’s over. The Galaxy Y GT-S5360 is going to afterwards reboot and, when “Pass” appears, you should disconnect the handset from your notebook.
