Update Galaxy Pocket Neo Duos S5312 to Android 4.1.2 XXAMD9

You need to have XXAMD9 on your Galaxy Pocket Neo Duos S5312 or else miss out on what Android 4.1.2 is all about.

Thanks to a developer, you can now upgrade your smartphone to the latest Android version in under half an hour. We are here to help you with everything, so prepare your Galaxy Pocket Neo Duos GT-S5312 for this firmware which was released in May 2013 for the June 2013 launched smartphone.

The Jelly Bean 4.1.2 XXAMD9 official firmware works for the Pocket Neo Duos that is available in Croatia, Greece and Romania (Cosmote) and running a custom ROM. Since the KIES logo isn’t activated, you won’t be able to update the device with Samsung’s KIES.

The features you will find on your smartphone after it’s updated are the following: a fixed frame of 60 fps, sync and connect email updates, triple buffering, mini apps, a new keyboard, touch anticipation and free style widget, group cast, pop up play, extended vsync timing, Google Now, automatic adjustment for the size of widgets, as well as all share. To try all of them out, it’s best that you own the phone model our tutorial deals with; if you have another smartphone, the guide won’t work and you will end up with a bricked device instead of a working one.

Bad news if you have a rooted Galaxy Pocket Neo Duos GT-S5312: this handset’s system partition and root access will be in trouble; while the former will get deleted, the latter will be revoked. The data and the internal/external SD cards, however, won’t suffer the same fate.Galaxy-Pocket-Neo-Duos-S5312


rest assured and follow this bunch of requirements:

  • create backups (a regular and a full NANDroid);
  • enable USB Debugging on the smartphone;
  • the USB cord of the phone should be kept close;
  • the laptop or PC’s operating system must be Windows;
  • should your phone’s battery levels tell you that you must charge your battery, do it;
  • turn off security software running on the handset and the laptop;
  • remember to flash USB drivers that work for the handset on your notebook.


  1. The tutorial is now off to a start. The first group of tasks has you doing this: download the XXAMD9 firmware (the Croatia version from , the Greece version from and the Romania Cosmote version ) on the laptop, then do the same for Odin file, available on this page. Once they are saved on the notebook in question, you have to find an unzipping tool and use it to open the two packages whose content must then feature on the same laptop (or comp, depending).
  2. When the extraction is over, you should prepare to enter the device in Download Mode by applying these steps: Volume Down, Power and Home at the exact same time and you’re done with this step.
  3. What should be done next is this: be sure to launch, on your laptop, the Odin as an Admin and, when this tool has been finally opened, you can plug the S5312 to the notebook (for which you should use the aforementioned USB cord) and wait for a successful connection to be established.
  4. Which will only happen when you spot an “Added!!” message and an ID:COM box painted yellow. If there’s no successful connection anywhere in sight, you need to take our cue and either install the USB drivers again or simply use another USB port for the job.
  5. Then continue with these steps: click on PDA, select a file with CODE in the name, click on Phone, choose a file with MODEM in the name, tap CSC; now choose a file with CSC in its name, click on PIT and choose a file that has .pit as its extension.
  6. You will then be asked to activate Auto Reboot, Re-partition and F. Reset Time. If you’re done with that, “Start” should appear, so click on it.
  7. The Android 4.1.2 XXAMD9 stock firmware needed for the upgrade will be flashed on your Galaxy Pocket Neo Duos. The process will end once the Samsung S5312 begins to reboot and then displays “Pass“.
  8. [sc name=”banner-jos”]Which lets you know that you should now do the following: unplug the devices from one another. The guide is now over and the new firmware is waiting for you in the device’s About Phone, which is in the Settings section.

Do you think the previous ROM is better than the new one? You can restore that one with the NANDroid backup file you had to create not too long ago. This is going to restore the old tool after the upgrade is revoked.
