After I have showed you how to update the AT&T Galaxy Note 2 with the official CM10.1 Android 4.1.2 ROM, now I will teach you how to install another powerful firmware on your phablet, the Jellybam software. Furthermore, according to those of xda-developers (we should thanks them for this tutorial) this version of the Jellybam system can be flashed on any LTE Samsung Galaxy Note 2 not only on the AT&T variant of the same, so you have nothing to worry about. Of course, if you own the international Galaxy Note 2, then you will have to use the guide from here (you have there a suitable Jellybam firmware for your device), as this tutorial will not work for you.
Jellybam is one of the most popular custom ROM available for the Android based smartphones, as the firmware is coming with important features and capabilities; actually the ROM is based on the CM10, AOKP and ParanoidAndroid platforms, so you will get a mixed software. Therefore, if you want to update your LTE Galaxy Note 2 with features, apps and capabilities ported from updates like CM10, AOKP and ParanoidAndroid, then flashing the Jellybam custom ROM is what you need to do. Of course, this step by step guide will take you through the installation procedure, so for more info check the same.
Now, if you want to learn more about the Jellybam custom ROM you can check our source page (use the link from here). As stated, the firmware has been developed and tested on the LTE Samsung Galaxy Note 2 by those of xda-developers, so we have them to thanks for the present tutorial. Actually, first the software was installed on the AT&T Note 2, but then the devs updated the system so that any LTE Note 2 devices can be installed with the Jellybam OS.
For being able to apply the CM10, AOKP and ParanoidAndroid based Jellybam custom ROM on your LTE Galaxy Note 2 the pre requisites must be first completed. Because of that you need to check and perform the tasks mentioned and explained during the next list.
- Gain root access for your LTE Note 2 or else you won’t be able to update it with a custom ROM firmware. By gaining root access you will unchain the system from the factory restrictions meaning that an unofficial update (like the present one) can safely be flashed.
- The warranty will get void, so try not to mess things up; if something bad happens you will be by yourselves.
- Restore the warranty by downgrading to stock ROM, or just reset the flash counter. By doing the same the root access will be revoked, so you will relock your phone’s system.
- Install a custom recovery image on your phablet. It’s extremely important to complete this step as the recovery tool will be used on the update operation; you cannot install the Jellybam software without using a custom recovery image.
- I recommend you to backup the Galaxy Note 2 data, or else you will lose the contacts, messages, call logs, EFS, internet settings, market apps and all of your personal saves and info.
- Also, make a Nandroid backup; in case something bad happens, or if you will not like the Jellybam ROM, then you will be able to restore the current firmware.
- Enable the USB debugging option on your handset and charge its battery (if there is less than 60% power left, if different you can skip this part).
- Remove the security tools that are running on your computer (you will have to use one) and on your device.
- Also, ensure that the antivirus protection is deactivated on the same.
- Remember that even though this version of Jellybam was first developed for the AT&T Samsung Galaxy Note 2, now you can flash the same on any LTE variant of the phablet; unfortunately for the international Note 2 you will have to use a different step by step guide (use the link from above).
