You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

SAMSUNG GALAXY GRAND DUOS OMNI ROM INSTALLATION

If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.

NOTE: Before you install the Omni ROM, your device must have been updated to 4.2.2 in the past. If you have not updated your device before, go to the below link and then you can come here and follow the Omni ROM installation process.

STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-I9082/GT-I9082L!

Please know that this page is meant only for Samsung Galaxy Grand Duos, model no. GT-I9082/GT-I9082L. Please DO NOT try the procedures given here on other variants of the Galaxy Grand Duos . Also, do not use the procedures discussed here on any other Galaxy device or any other company. You have been warned!

STEP 1: BACKUP YOUR DEVICE:

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

STEP 4: INSTALL THE LATEST CWM RECOVERY

Skip this step if you already have latest version of CWM recovery installed on your device.

So to install the latest CWM recovery view the links given below

GUIDE FOR CWM RECOVERY

Example video: If you haven’t used CWM recovery before to install a .zip file of a ROM or anything else, then we suggest you first watch a video of that to get familiar with the process. Click here to watch the video

Boot into recovery mode. For this:
- Power off your device and wait for 5-10 seconds until the device is fully switched off.
- Press and hold Volume Up + Home + Power button together and release them as soon as you see the Samsung logo.
  └ In Recovery mode, use Volume buttons to navigate up and down between options and use Power button to select an option.
Create a Nandroid Backup from recovery. It’s optional but very important to do, so that in case something goes wrong you can restore to current status easily. For making a Nandroid Backup, go to Backup And Restore » Backup.
Perform a Factory Reset (this will delete all apps and their settings and game progress). For this:
- Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot)
First Install the ROM file:
- Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the ROM file
Now similarly flash the Gapps file.
└ Make sure to first flash the ROM file and then the Gapps file.
The ROM is not pre-rooted, so now flash the Superuser file after flashing the Gapps.
Reboot your device. For this, go back to the main menu of recovery and select reboot system now.

That’s all. Your phone will now reboot and it will take some time as it’ll be phone’s first boot after installing Omni ROM, be extremely excited for this!

Note: In case your device gets bootloop (stuck at logo while rebooting), just do a factory reset (step 3) and you will be fine.
