So, it is important to emphasize that the Jedi Master software is an Android 4.1.1 Jelly Bean based update that has nothing to do with Samsung therefore the same is not an official OS available for your T-Mobile Galaxy Note 2. In fact, the ROM has been developed and launched by those of xda-developers, so we have them to thanks for the present step by step guide. According to our sources, the OS is stable and it is coming with no bugs or issues; furthermore important features will be added to your Note 2, meaning that the phablet’s performances will be improved.
Now, if we are to talk about the Jedi Master custom ROM, first we need to mention that it comes with the Android Jelly Bean 4.1.1 flavor. Then, the most relevant features and capabilities are including: CPU Sleeper, SuperSU, BusyBox, Sony’s Bravia Engine, Walkman Music, Awesome BEATS, and Jedi Ringtones. Also, the software is rooted, deodexed, partially debloated, and zipaligned. So, as you can see you have all the reasons for installing the Jedi Master firmware on your Note 2 T889. For that you will need to complete the pre requisites along with the steps from below, all being explained and detailed so that everyone can understand what to do.
And you should begin with a root operation. Yes, that’s right, for being able to update your phablet to Jelly Bean 4.1.1 you will first have to root the T-Mobile Note 2. This implies in voiding the warranty, so be careful in what you do. If somehow you will manage to damage your device, then you will be by yourselves. That’s why you must read all the following lines; don’t skip any section as this is being considered a risky and complex procedure.
Regarding to the warranty, don’t worry as you can anytime restore the same. You see, when you flash a custom ROM the flash counter of your handset will be increased; this is how the carrier can tell whether you have made an unofficial operation on your device or not. So, for restoring the warranty all you need to do is to reset the flash counter and this can be performed with a downgrade to the stock ROM operation. The same result can be obtained if you update the Galaxy Note 2 with an official OS provided by Samsung. Also, if you do manage to brick your handset, you can use our tutorial for learning how to easily unbrick the T-Mobile Note 2.
Now, after gaining root access, you will have to download and install a custom recovery image, such as CWM recovery on your smartphone. This app will be used a little bit later, when I will show you how to update the Note 2 to Jedi Master Jelly Bean 4.1.1 custom ROM by suing the recovery menu. Take note that the CWM recovery tool can be installed only on a rooted system.
Then, a backup is also required as all of your personal info will be wiped out. This is happening because a full wipe of the system will have to be performed; else the custom ROM will not work properly. For applying a full backup you can use suitable apps from Google play; if you don’t know how, consult our backup and restore tutorials by checking out our how to section. You can easily save the contacts, messages, call logs, internet saves, EFS and everything else you need to. It is recommended to make a Nandroid backup too, so if possible complete the same.
Also, a Windows running computer, the phablet and its USB cord will be required, so make sure that the same are near you. In order to avoid the unpleasant situations, before starting the update process, deactivate the security programs (like antivirus and Firewall protection) from your computer and Galaxy Note 2. Also, charge the battery of your (if there is less than 60% power left) device because else it might get turned off in the middle of the update. Enable the USB debugging option on your smartphone and make sure that this tutorial is being completed for the T-Mobile model of the Samsung Galaxy Note 2 model number T889, or else you will risk in bricking your handset.
