For people who possess the first generation of Galaxy Note (N7000) and search for the Jelly Bean update, you may need to check the following step-by-step guide on how to update Galaxy Note to Jelly Bean 4.1.2 on your own.
There will be a few enhanced features included in this Jelly Bean update which include Buttery Smooth Performance & Great Stability (Thanks to Project Butter), Multi-View (Multi Windows Multitasking, just like in Note 2), Multi-View may also be disabled, Ripple Effect on Lock Screen, Page Buddy, Notification Panel can be personalized, New Additions in Notification Panel, Smart Rotation (Screen Display adjusts to your angle of sightings), Continues Input in Samsung Keyboard (Like Swipe or Android 4.2 Keyboard), Samsung’s Cloud services, Direct Call, Smart Stay and Pop-up Play Features, New Widgets From the Galaxy S3, Two Home screen modes, New Notifications bar along with the Google Now app.
Prior to doing the update process, you must make sure that your Galaxy Note has been already mounted with at least Android 4.0.4 (Ice Cream Sandwich). It’s highly recommended to backup the entire data first because this process will require you to format all the data on your device. Furthermore, you need to install Samsung Kies on the computer or laptop. Lastly, determine whether you have attached the microSD card on your handset.
This update process requires you to root the Galaxy Note initially. To get it done, you must download cwm. zip and SU-Busybox-Installer. zip and then save the files on sd card. Set your phone to the Sistem Recovery mode by pressing and holding the Up Volume Power Home simultaneously. The phone will restart and wait until you see the System Recovery screen (here you can stop pressing those buttons).
Pick the “apply update from external storage” menu and then try to look for the cwm. zip file that you’ve formerly saved on sd card. Press the Up or Down Volume button to navigate and utilize the Power Off button to pick the file. When you’re on the CWM (ClockworkMod Recovery) screen, choose the “Install Zip from SD card”, then choose the “Zip from Internal SD card”, and then install SuperSU. zip. If everything’s ok, you can choose “reboot system now” and that’s it you have successfully rooted the device.
At this point, you need to customize the kernel of the device. First of all, download the Mobile ODIN Lite from XDA. Remember that the Mobile ODIN will download a few files so it will require data package or WI-Fi connection. Then, you have to download SpeedMod Kernel and then store it to the internal or external storage. Next, you can now set up and open the Mobile ODIN (pick the Grant Access option and let it download any files as needed). Click on the Kernel and direct it to the SpeedMod Kernel that you’ve formerly stored on internal or external storage. Finally, choose the Flash Firmware option and you have done rooting the handset.
To update the Galaxy Note to Jelly Bean, you must download the ROM Jelly Bean 4.1.2 (700 mb). After you have finished downloading the ROM, you will need to save it to your sd card. Go to the System Recovery Mode once more and then opt for “Wipe Data/Factory Reset”, “Wipe Cache Partition”, “Install Zip” and then search for the ROM file that you’ve formerly saved.
