Although Galaxy Mega 6.3 is equipped with brilliant hardware, yet there is room for improvement. These improvements can be made only after rooting it. Most of people must be aware of the fact that rooting voids warranty and so think if it something bad or not safe. Gone are the days when rooting was something unsafe. So, there is no need to worry about that. The question left is that why one must root the device, only to void warranty. Rooting an Android device grants its owners extreme rights. A rooted Android device can be moulded into anything. All system protected/locked files are available and one has to modify few codes to get the required results. There are few things that cannot be changed without rooting device. We will discuss more about it later. The second part of this guide is related to installing ClockworkMod custom recovery. Every Android device comes with a pre-installed stock recovery. It is basically same as a custom recovery but it has limited functionality. A recovery is used to control OS without booting into it. It is used to flash firmwares manually and many other mods. A custom recovery can be used to flash more stuff than a stock recovery. A custom recovery is filled with many other useful features like Nandroid backup, ADB mount and others. Therefore, a custom recovery is essential if you are planning to do some cools stuff with your device.

This is not a one-step process. It is not long either. You only need to be patient and careful If you become to hasty, you might repent later. So, take proper time and complete every step given here carefully. Make sure that you complete all the requirements given below and then proceed to the next step. All of these steps are mentioned to make sure that your device remains safe.

Important Precautions

1. ADB and Fastboot Drivers:

ADB stands for “Android Debug Bridge”. ADB is essential to establish a connection between you android device/android emulator and PC. If you are a developer, or an android device owner, who wants to mess with his android then you will need ADB & Fastboot installed on your PC. ADB and Fastboot drivers are essential to detect your device while it is connected to computer.

3.Battery must be charged over 70%:

This is the most important precaution. If you have done everything right and while you are doing it and your phone turns off, there’s no telling what will happen to your device. Normally, the whole process will take less than few minutes and some people might consider doing it without charging the phone. As a matter of fact, many times I have got my self into such situations that because of low battery, my phone turned off in mid and you can know the rest. However, it was not so hard to revive those devices and I have not yet damaged any device. So, just follow whole guide and you will be safe as well.

4.Check your Phone Model:

There are a lot of variants of devices and sometimes it gets hard to distinguish them without seeing the technical information. Using a wrong file can potentially brick your device. In most of the cases, devices can be recovered, but don’t be too careless with your device. Always confirm that the guide you are following is for your device. You can learn about your device’s model name by navigating to Settings>About Phone. After you have confirmed your phone model, you can proceed further.

This Guide is only for Galaxy Mega 6.3 I9200 and I9205

5.Do not turn off Computer during Updating Process:

This mistake has same effects as having low battery on your device. That is why be careful to keep your computer plugged in during whole process.

6.Backup all your important Data:

Normally, rooting process does not wipe out your data but to be on the safe side, it is advisable to backup your data so that you can recover it in case of data wipe. If you are using a SD Card, remove it before rooting and insert it again after rooting has been done. Backup all data on internal storage on your computer. Backup messages and contacts by using methods described above. Follow this BACKUP GUIDE. If your device is rooted, BACKUP DATA WITH TITANIUM BACKUP.

If you already have TWRP or CWM recovery on your device, then you should make a Nandroid Backup. In case something goes wrong or you don’t like new update, you can easily go back to previous ROM easily.

6.Use correct file for your smartphone:

Sometimes we have lots of files, having similar names put together in same folder. Accidentally, we can use a wrong file which can result in bricking device. Therefore, it is advisable to put specific files for your device in a separate folder. This way, you will not be mistaken.

7.Get Developer Options Enabled:

In android 4.2.2, developer options are hidden. Developer option are provided for development purposes like rooting itself. It is second-last tab but you may not find it yet. To activate Developer Options you need to navigate to Settings>About Phone. Tap build number about 7  times until you get a pop-up saying your are a developer. In Android 4.1.2, developer options are already visible.

In case you face any connectivity issues, it might resolve issues.

8.Backup EFS Data:

Before flashing anything like a custom ROM or a custom mod, you must backup EFS data. If anything goes wrong and you lose this data, your phone will lose phone signals. You can backup EFS data using TWRP recovery provided here. Once you have backed up EFS, there is nothing to worry about. You may now flash the custom ROM without any worry. There are number of applications available on Play Store for this purpose or you can do it manually using Root Explorer.

Required Downloads

Download the files for your device’s model number only. The recoveries used here are Philz Touch Advance CWM recoveries. SuperSU is developed by Chainfire.


Remember that all processes like rooting, flashing and manual updating are custom methods. They have no concern with Google or mobile manufacturer. Follow every step carefully to avoid any mishap. Owner of site will not be held responsible in case of any mishap. Do it at your own risk. Rooting and flashing custom ROMs will also void warranty.

  1. The next message shows up : There is no SU binary installed, and SuperSU cannot install it. This is a problem. If you just upgraded to android 4.3, you need to manually re.root – consult the relevant forums for your device.

    Any advice?
