If you are one of the thousands of buyers of Samsung’s Galaxy Grand Duos then you may have been got tired by waiting for Android 4.4.2 KitKat update on your device. If you are person who doesn’t like to wait this long and are willing to take some action then this guide is probably for you.
Some time ago I gave you people a guide on how to root your Galaxy Grand Duos. You will have to follow that guide and root your device before we proceed here on installing the custom ROM.
Before we start:
Before we start flashing the custom ROM you need to take care of some things.
- Make sure you download the official ROM along with custom ROM for the device because if you happen not to like the custom ROM then you could flash official ROM instantly. Backup your important data on your computer.
- Make sure you have correct USB drivers for the phone installed in your computer. If you don’t have the drivers here is the link (Drivers) go grab them first.
- See if your phone is charged up to 80 per cent because flashing drinks up a lot of juice and you don’t want to brick your device for sure.
- Also see if your phone is network unlocked.
- Rooting and flashing voids your device’s warranty and also they may cause damage to your device so keep this thing mind as we will not be responsible for any damage.
Download custom ROM and Google Apps from the link below:
- First of all you will have to connect your Grand to your computer and transfer the Custom ROM and Google Apps we downloaded above into your phone.
- Now we have to boot phone into recovery mode and for that you will have to switch off your device. After that you will have to use combination of Volume Up, Power and home buttons.
- In recovery mode, go to Wipe data and select that option and that go to main menu from where go to advanced option and select Wipe Dalvik Cache.
- Now again go to main menu and this time select “Install Zip from sdcard” then go to the custom ROM’s zip which we transferred to the phone in the first step.
- As soon as this process completes again go to “Install Zip from sdcard” and this time install the Google Apps which we transferred to phone’s storage in the first step along with Custom ROM.
- Again go to main menu and this time select “Reboot system now” option and wait for phone to restart.
Now your phone is running on latest version of Android KitKat. In case you happen to stuck at boot loop then go to recovery mode and perform factory reset once again.
If you want to ask us anything, make sure you do that in comments section below. In case you want developer to add some tweak or improve the ROM then you can contact him at this XDA thread link.
