The Samsung Galaxy Note 2 LTE N7105 can now be updated with the most popular Android based custom ROM, the CM 10.1 Jelly Bean 4.2.2 firmware and all thanks to those of xda-developers who had made available the software for the mentioned devices. So, now the LTE variant of the Note 2 can anytime be installed with the latest features, apps and capabilities, not to mention that those who will flash the CM10.1 ROM will also update their phablets to Android 4.2.2 Jelly Bean OS.
This is the official and nightlies version of the CM10.1 custom firmware therefore we are dealing with a stable OS improvement that will smoothly run on your LTE Galaxy Note 2 N7105. Furthermore, by flashing the same you will be able to power up the performances of your handset as the system will be customized and optimized, you will receive increased speeds, a better web browsing experience, the battery life will be improved and more (check our source page from here for further details about the CM10.1 features). For enjoying the same all you have to do is to read and apply this step by step guide which will easily take you through the installation procedure.
CM 10.1 is a custom firmware that brings features that cannot be found in the default version of the Android system. Of course it is based on the Android OS(in our case Jelly Bean) and can be installed only on Android powered devices (like the Galaxy Note 2). As it is a custom ROM, you cannot flash it without preparing your handset, so you have to apply the pre requisites. Also, the installation procedure is a complex and risky one, meaning that you might end up in bricking your smartphone if something isn’t working well (you can avoid this by following a dedicated tutorial, like the present one).
Unfortunately, by applying the CM10.1 platform on your Galaxy Note 2, you will void the warranty of your device. Actually this is happening because you first have to root your phablet, this being the first task that must be completed before heading to the proper installation guide. The software needs to access some internal files and inbuilt programs from your device, this access being granted by the root operation. So, the warranty will be lost; a final tip: you can restore the warranty as soon as the stock Jelly Bean 4.1.2 OS is being updated to your LTE Samsung Galaxy Note 2.
Once the Note 2 is unchained, you need to get and flash a custom recovery image into its system. The CWM recovery one is the most used recovery by the Android users, so you can anytime apply the same. The tool will be extremely important to us because the CM10.1 JB 4.2.2 custom ROM can’t be installed on your phablet without using it. Also, you might want to backup the Galaxy Note 2 LTE data before going any further because all of your personal info will be wiped out; and a Nandroid backup is recommended too, because in this way you can anytime choose to restore the current ROM without performing a new and complex manual method.
Then, the rest of the pre requisites are more general as you have to make sure that a computer can be used; also you need to deactivate the Firewall and antivirus protection (and uninstall all the other security tools that are running on the same) from both computer and device; enable the USB debugging option on your Note 2; charge the phablet or else it might get turned off in the middle of the operation; apply the next steps only if you own the LTE version of the Samsung Galaxy Note 2 (model number N7105).
If you don’t like the CM10.1 ROM or if you think that you might want to check other updates before deciding in which platform to choose, take a look over our “update Galaxy Note 2 LTE” section and pick one of the ROMs described there.
