How to Flash Android 4.1.2 DDUAML1 on Galaxy Trend Duos GT-S7392

Samsung just launched DDUAML1 for Galaxy Trend Lite Duos GT-S7392. What this means is the following: your smartphone will enjoy the newest Android 4.1.2.

The update we are about to describe here brings the features of the Jelly Bean 4.1.2 directly to your handset. The DDUAML1 official firmware is available for India, Sri Lanka and Nepal as well. So prepare your Galaxy Trend Duos GT-S7392 (not another model) and follow our steps!

KIES software cannot be used for the update: the firmware’s KIES logo is turned off. This translates into the following: only OTA or our guide can be used for the upgrade. For OTA, your device must be running stock ROM. You won’t need this ROM running on your phone if you resort to our tutorial.Galaxy-Trend-Lite-Duos-GT-S7392

Prerequisites

Below the following requirements we have some info on the new features brought on by the update. Here are the pre-requisites for now:

  • turn on USB Debugging on your smartphone;
  • take a quick look at your handset’s battery and charge it in case that’s needed;
  • always use a notebook which is functioning with Windows;
  • disable all of your phone’s and laptop’s security programs;
  • on this page you’ll find USB drivers compatible with your handset;
  • download and save them on your notebook;
  • create a normal backup using this tutorial;
  • make a full NANDroid backup.

The update will deliver touch anticipation, a fixed frame of 60 fps, Google Now and mini apps. Other novelties: sync and connect email updates, pop up play, triple buffering and extended Vsync timing. If these aren’t enough, there’s more: all share, group cast, automatic adjustment for the size of widgets, a new keyboard and free style widget.

You should, if your device is rooted, be careful of the following: the new firmware’s going to delete system partition and then revoke root access. You don’t have to worry over the important data: your phone will not lose it. The device’s internal and external SD cards will not be damaged, too.

Step by step instructions

  1. For step one, do as follows: to find the Jelly Bean 4.1.2 S7392DDUAML1 for India, for the Sri Lanka version and for the Nepal variant.
  2. When you locate the right version for your Galaxy Trend Duos GT-S7392, download it on your laptop, then download, on the latter, Odin from this site. 7Zip or WinRar need to be used next for this task: extract the two packages you saved on your notebook.
  3. Boot the smartphone in Download Mode afterwards by pressing and holding Home, Volume Down and Power together, let go of them once a boot screen comes up, then be sure to only press Volume Up.
  4. Continue by launching Odin as an Admin on your laptop via these instructions: right-click on that .exe file and tap “Run as Administrator” when you’re done.
  5. You should do this now: connect the handset to the notebook. After making use of the phone’s USB cord for this part, wait for the Odin to look for your smartphone. When it will find it, you should see a message reading “Added!” and an ID:COM box.
  6. If they take too long to appear or don’t appear at all, try several alternatives. Like using another USB port or re-flashing those USB drivers on the laptop.
  7. Tap BL, opt for a file with BL in the name, tap AP next and after that choose a file with AP in the name, tap CP, opt for a file with CP in its name, tap CSC, choose a file which has CSC in the name, tap PIT and opt for that file which sports an extension named .pit.
  8. Check these boxes for the next set of tasks: F. Reset Time, Auto Reboot and Re-partition. As for how to begin the installation of the new firmware: tap “Start”.
  9. A good indicator for the end of the installation is your device rebooting. The handset and your laptop should be unplugged once your handset’s touchscreen comes up with “Pass” in green.
  10. [sc name=”banner-jos”]The DDUAML1 is now on your Galaxy Trend Duos GT-S7392. To find it quickly, we suggest tapping Settings and then About Phone. You should now try the firmware out and see what it’s all about.

When the new firmware doesn’t seem that attractive, look for the NANDroid backup file. It will soon restore your smartphone’s old ROM by revoking the update process.
