Root your smartphone / tablet.

Install a custom recovery image on your device – you can use any recovery tool you want though it is recommended to flash CWM or TWRP recovery. The custom recovery will be used on the flashing operation as the stock recovery that comes pre-installed on Android can’t be used on unofficial procedures.

Backup the data which is saved on the internal storage memory of your handset; save everything you might need including text messages, call logs, internet settings, market apps, EFS folder and so on. Also, consider in making a Nandroid backup for saving the current software.

For these operations a computer is being required along with your smartphone / tablet and with the USB cable.

On both devices and computer you should first deactivate the security protection; the antivirus programs are usually interfering with the update operation.

Your device must be charged especially if the battery status indicates less than 60% power left; the handset might get bricked if it gets turned off while you are trying to install the custom firmware.

On your phone the USB debugging option must be enabled: “Settings -> More -> Development Options -> USB debugging”

1.First of all, on your computer you need to download the proper update file.

2. Copy-paste or drag and drop the downloaded files from desktop to your phone’s (tablet’s) SD card.

3.Disconnect the devices by unplugging the USB cable.

4.Turn off your smartphone / tablet and wait a few seconds.

5.Then reboot your gadget into recovery mode.

6.Next, navigate through the recovery mode menu and select “wipe data factory reset”, “wipe cache partition” and “wipe dalvick

cache”.

7.The system will now be wiped out, so that’s why the backup has been recommended before.

8.Up next, return to recovery main menu: select “+++go back+++”.

And choose “install zip from SD card” and “choose zip from SD card”.

9.Pick the update file and flash the same.

10.When the installation process ends, from recovery select “+++go back+++” and “reboot system now”.

You are done.
