How to Root and Unroot Galaxy Note 2 N7100 with ExynosAbuse

There are several ways that can be used for rooting the Samsung Galaxy Note 2 (by using Odin or by using the CF-Auto-Root package), but most of the procedures are quite complex and risky as you can easily end up in bricking your device. Fortunately for us, those of xda-developers found a better way for rooting the Galaxy Note 2 N7100, and this by taking advantage of the well-known system vulnerability that affected the Exynos handsets. So, today, I will show you how to easily root and also unroot the Note 2 by using the new ExynosAbuse app.

The best part related to this method is that it offers both root and unroot solutions for your Galaxy Note 2, so you can easily re-lock the phablet’s system after completing your plans. For example you can gain root access for removing some internal files and apps (built-in tools) that are slowing down your smartphone and then you can easily unroot the OS for enjoying the pure and default Android system on your Note 2. Also, the operation which will be explained below (that uses the ExynosAbuse app) brings an intuitive root / unroot solution, the actual guide being easier than the other ones that are using Odin.

The root access must be gained if you want to have access to the internal system of your device. You see, when you buy a new phone, or tablet it will be delivered with a locked OS, so if you want to access the same you need to remove the factory restrictions and the default settings. For that you need to use and apply suitable root guides, which will grant the mentioned access.

After rooting, you will be able to customize, optimize and power up the system and the performances of your Galaxy Note 2 for receiving improved speeds, better battery life and more. You will be able to install complex apps that requires root access in order to work properly (like CWM recovery), or you can update your Galaxy Note 2 with a custom ROM firmware, so as you can see, completing the present step by step guide is no longer an option for you.

Considering the up-mentioned details, it should be clear for you that a root operation is not official and performing the same means that the warranty of your device will get void. Well, usually, after rooting if you want the warranty back, or if you want to revoke the root access, you need to downgrade to stock ROM or apply an official updated. But, by using this tutorial, if you need to restore the warranty and revoke the root access, all you need to do is to follow and complete the unroot method that is being explained during the proper steps from below. In this way you can restore your Samsung Galaxy Note 2 to its default version.

Due to same reasons (this is an unofficial operation which was first developed by third party devs – those of xda-developers) before heading to the root / unroot Galaxy Note 2 N7100 step by step guide, you first need to prepare the phablet by completing the essential and general pre requisites.

  • Backup the Note 2 data before going any further. All of your personal info might get wiped out and you can lose your text messages, call logs, internet settings, calendar info, contacts list, EFS and everything else. Because of that we recommend you to use our backup and restore guides (search through our how to section for the same) before rooting your Note 2.
  • Charge the battery of your smartphone, or at least make sure that there is more than 60% power left; else your device might get turned off in the middle of the root / unroot operation and you will risk in bricking your Galaxy Note 2.
  • Don’t forget that this tutorial has been developed and must be applied only by those who own the Samsung Galaxy Note 2, model number N7100. Using the same on a similar handset might brick the device.

    hi i have been reading a lot about exynos chip problems etc and came to realize exynos abuse app which many recommend from chainfire is the easiest way to root and unroot phone. not only that it gapes the holes for nasty viruses to intrude the exynos chip. but one thing i am not sure what chain fire says in his discription about exynos app is—Also note that if use the patch method without rooting, or keep patching the exploit at boot enabled when unrooting, you need an alternate method to re-root the device to disable this feature (like CF-Auto-Root) – you cannot use ExynosAbuse to do this since it patched the exploit. Unlike other patch authors, I do not believe in keeping an invisible rooted process running in the background while pretending you aren’t rooted, to be able to unpatch this way. Also i saw pics of exynos app photos on 1 of the forums, in one of the photos it says under Unroot device option- keep the patch which that disables the exploit at boot in place. note that this will prevent from using exynos abuse app again..I do understand there is some sort of exploit which we are patching using this app apart from rooting the phone just to stop those nasty viruses. and if we unroot the phone the patch will stay in place at every boot on the exploit so if we have to root again we have to use other method like cf auto root etc..can anyone kindly shed some light on what exploit is and what is the limitation and advantage of exynos abuse app. What is exploit and what does it mean in the app where it says exploit is disabled and exploit disable on boot.? Also why do we have to update binary.? Do we have to click disable exploit right after rooting as others or youtube videos say or do we have to use them only while unrooting.? With this root methods can we install custom firmwares or no. ? thanks..
