The DXLSE Jelly Bean firmware can be installed using Samsung Kies. But Galaxy Note users who failed to install the update using the official method may follow our step-by-step guide below. IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Before following the tutorial, users are advised to ensure that their devices meet requirements below. 

Pre-requisites

1) Install USB Driver for Samsung Galaxy Note on the computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.] 

3) Create back-up of all data of the device.

4) The Galaxy Note should be factory unlocked and should not be locked to a particular carrier.   

5) Ensure that the battery of the Note has above 80 per cent charge.

6) The device will lose custom ROM with the installation of official firmware.

7) The Android 4.1.2 DXLSE Jelly Bean firmware is compatible only with Samsung Galaxy Note N7000; applying this to any other variant will brick the device.
