Install New Rom On Galaxy S3, S4, S2, Note 2, Note 3

Download Firmware from here

Download Odin:

Odin is the unofficial version of Samsung’s tool for installing firmware to its Android devices. To be able to install a firmware on your Note 3, you will need this tool. Unfortunately, Odin is not available for Mac or Linux and so you must have a Windows PC to use it. If you have a Mac or Ubuntu computer, you can download and  use Heimdall for the purpose.

Odin_v3.09.zip 

Booting Galaxy Phone in Download Mode:

All Samsung Galaxy devices need to be booted into Download Mode before installing a firmware using Odin. You can put your Galaxy Note 3 into Download mode by pressing Volume Down + Home + Power buttons together for 2-3 seconds. When the screen turns up, you’ll be asked to press Volume Up to enter Download mode. Do it.

Enable USB Debugging :

Before installing a firmware, USB Debugging must be enabled on your Galaxy Note 3 by going to Settings> General> Developer options.  Developer options are hidden by default on all Android device running Android 4.2 and up. To make them visible, go to Settings> General> About on your Note 3 and tap Build Number for 7 times.

When it is done, go back to Settings panel and you’ll be able to see Developer Options there. Tap on it and select USB Debugging. This mode prepares your device by allowing the computer to make changes to your device.

Install Samsung USB Drivers or Kies:

The presence of USB Drivers from your device OEM is a must have if you want your phone to connect to your computer system. Without appropriate drivers, a successful connection is not possible. Therefore, you must install either Samsung USB Drivers, or Samsung Kies on your computer before being able to install a firmware file. Make sure that you have not installed both. Install either the the drivers or Kies. In case you have the latter on your computer, do not forget to close it while installing the firmware via Odin, or you might get into problem.

Download Samsung USB Drivers or Kies

Backup Your Phone’s Stuff:

Samsung’s firmware are usually of two type: wipe and no-wipe. In most cases, the firmware have no-wipe attribute and means they do not wipe your phone’s data and apps or reset it. Since firmwares do not warn us whether  they will be wiping the data or not, it is very important that we act prudently and be prepared against data loss in advance.

Also, whether a firmware deletes your phone’s data or not, we always recommend that you perform a data/factory reset after installing a new firmware to avoid slow performance and battery drain. We would talk about it later. To backup your apps, games, contacts, messages, call-log, etc., you can take help of these handy apps.

Using Odin to Install Firmware:

1. Download the appropriate firmware file. If it is packed in a .Zip or .Rar archive, extract it on your computer. All firmware files have .tar.md5 extension.
2. Download and extract/unzip the Odin zip file and launch the .exe file by double-clicking it.
3. Boot your Phone into download mode by turning it off and pressing the following key combination: Volume Down + Home + Power.
4. Connect the device to computer using USB cable and wait till Odin detects it. A successful connection is indicated by Blue signal at ID:COM and “Added!!” text at the message box on Odin.
5. “Auto Reboot” and “F. Reset Time” options are selected on Odin by default. Let them be as they are and do not check any other option on Odin.
6. If you are using Odin3 3.09, click on “AP” button, navigate to the firmware file and select it.
7. Finally, hit the “Start” button and wait till the installation finishes. It might take a few minutes to complete.
8. When the firmware is installed, you will see “PASS!!” message on Odin and your Note 3 will reboot automatically.

The first boot after installing a firmware takes a longer time than it takes usually. Wait for a while and then your phone should be ready to use.

Fixing a Bootloop on Galaxy Note 3:

Sometimes a little obstacle pops up while your phone tries to boot up. Bootloop is a situation where your see the device logo or animation repeated constantly. The clash between two incompatible files in the system after installing a new firmware often causes bootloop. To fix it, do the following steps:

1. Pull out the back cover of your Galaxy Note 3 and  take out the battery.
2. Wait for a minute and place the battery back to it place.
3. Then press and hold the Volume Up + Home + Power keys simultaneously till you see the Samsung logo appear-disappear-appear and disappear again. It’s just the moment when you have to release the Power button. Keep the other buttons pressed till you see a green Android robot followed by Android System Recovery.
4. Here you’ll see a small list of options in blue text. This screen does not support touch, so use the volume keys to scroll/highlight and the power key to select an option.
5. Go to “wipe data/factory reset” option and confirm your choice by selecting “yes”.
6. Finally, select “reboot system now”.
7. Your Note 3 will boot normally now.

How to Root Nokia X and Install Google Apps on It

It all began with rumors the last year that Nokia had secretly been recruiting developers to work on an Android phone. The news was a sensation at the time and after that we kept hearing about an Android phone by Nokia under development now and then. We’re just about to forget about a possible Android phone from Nokia after the company was occupied by Microsoft, when new rumors began creeping in. Finally, it was at the MWC, Barcelona the last week when all rumors came true and we saw the first authentic glimpse of the Nokia X.

The Nokia X is now a reality and now, even before the device has been released, we have another real news. XDA forum member Kashamalaga has discovered that one of the most popular root exploits for Android devices, is working fine on the Nokia X. As you know, the Nokia X has a home launcher that is very similar to the one seen on its Windows phones and it has its own apps store. Also, the device does not have Google apps preinstalled as we are used to see on Android devices.

As we already mentioned, Kashamalaga managed to root his Nokia X and with his efforts, was able to install the Google home launcher and other Google apps on it. Now, this is really a great news for those who are waiting to get the Nokia X. With root access gained on the device, it is now possible to do all sorts of customization and tweaking on it.

How to Root Nokia X:

Rooting an Android device using Framaroot does not require a tutorial as such, yet here are the steps:

1. Download the  latest version of Framaroot app: Click Here
2. Copy the APK file to your Nokia X.
3. Go to the file using a file manager and install it. If you are prompted to enable Unknown Sources option, do it.
4. Now open Framaroot from app drawer.
5. Tap the Gandalf exploit.
   
6. Your Nokia X will be rooted in a matter of seconds.

Installing Google Apps on Nokia X:

Having rooted your Nokia X, you now have privilege to access and modify your device’s system. Here’s how you can install Google apps and services on your phone:

1. Download the Google apps package, specially packed for the Nokia X: NokiaX_Gapps_KashaMalaga_28.02.2014.zip
2. Install a root file manager on your device. 
   
   

   

   Download @
   Google Play
   

   Root Browser

   Developer: JRummy Apps Inc.

   Price: Free
   
3. Extract the Google apps (Gapps) ZIP and copy the folder to your phone.
4. Now launch Root Browser and navigate to the Gapps folder.
5. Mark/select all files present inside it and select Copy.
6. Now go to system/app directory and paste the files here.
7. Go to each app that you just copied and set the permissions for each as rw-r–r– (0644).
8. To do so, tap and hold the app and select Permissions.
9. Then set the permissions as shown above.

When you are done with fixing the app permissions, reboot your Nokia X. When the phone boots up, open Google Play Store and sign in with your Gmail account. Enjoy Google apps and services!

How to Boot Android Devices in Fastboot, Recovery and Download Mode

Whether you own an Android Smartphone or a tablet device, whether you are a noob, basic or advanced user, you need to be aware of certain things about your device. Booting your device into Odin/download/fastboot/ bootloader or recovery mode (stock or recovery) is  a piece of knowledge you must have.

There are hundreds of Android devices out there manufactured by different OEMs. As a result, there is no universal method for entering download/fastboot/recovery mode for all devices. The key combinations differ even for the devices made by the same manufacturer. At Droidviews, we always strive to provide tips, tricks and resources for our visitors that might make their mobile life easy-going and productive.

With this end at the back of our mind, we bring together the keys to boot your Android device in download/fastboot/bootloader and recovery mode at a single spot. We aim to make this article a handbook for such purposes and therefore we have made a beginning with most recognized and popular brands like Samsung, LG, Motorola, HTC, SONY, Asus, etc. and we plan to add more brands and devices, making this article all inclusive and, at the same time, an exclusive presentation from Droidviews.

Disclaimer:

Please note that you will be able to boot your device in custom recovery mode only if it is rooted. We don’t take any responsibility as by rooting you already have given up on your warranty, please don’t proceed if you don’t know what you are doing.

Please be noted that this guide is a work in progress and will grow larger. Some specific device could actually have a different key combination or some device could behave differently, if you have any trouble with the following tutorial, or if you have pointed out a non working key-combo, please drop a comment and we will be happy to help you.
