Update Galaxy Note 2 LTE N7105 with Jelly Bean 4.1.2 WanamLite Custom ROM

If you thought that the LTE version of the Galaxy Note 2 has been left aside from the custom ROMs treatment, I do have something to cheer you up: those of xda-developers are bringing new updates for your phablet, the suitable tutorials being explained here on Android.gs, so don’t hesitate and follow our guides. Anyway, after I have showed you how to flash the Android 4.2.2 based ParanoidAndroid software on your Note 2 N7105, now I will teach you how to apply another Jelly Bean based custom ROM on your device: the WanamLite platform.

If the ParanoidAndroid system was not stable enough for you (only the preview built of the same is available for now) the WanamLite firmware will be on your taste because this is the bugs-free variant of the OS. Therefore, everything is smoothly working on this ROM, not to mention that many extra features (that cannot be found in the default version of the Android system) and capabilities will be added to your Galaxy Note 2. The installation procedure is being explained below, but first do make sure that you read and apply all the lines from this step by step guide.

Here is what you need to know about the WanamLite custom ROM: the update has been first developed and tested on the Galaxy S3 and Galaxy S2, the users who had tried the firmware being pleased by its performances (that’s why now you can flash the same on the Galaxy Note 2 LTE); the update is being based on the Android 4.1.2 Jelly Bean OS; the software is deodexed, rooted and zipaligned and once it will be installed on your device you will notice that the battery life has been improved, the speeds increased and the internal system customized and optimized. Now, if you want to learn more about the WanamLite ROM, check our source page from here.

This is a custom ROM, which means that the update isn’t coming from Samsung, so you cannot OTA or by using KIES apply the same. A manual method is being required and performing it will make you void the Galaxy Note 2 LTE N7105 warranty. Unfortunately this aspect can’t be voided as a root operation must be previously completed. Therefore, be careful in what you do and try not to mess things up. As a final tip related to the lost warranty, you can anytime restore it by downgrading your device to the stock firmware (use the tutorial from here) though then the root access will be revoked and all the factory restrictions reinstalled.

I have mentioned something about a root process above; well you do have to root your Galaxy Note 2 LTE before going any further as the Jelly Bean 4.1.2 based WanamLite software must access some internal files from your device; the same is granted by the root access, so you can’t update your Note 2 without completing this task. This is when the warranty will get void, so be careful in what you do. Then, after rooting, you also have to install a custom recovery image, like CWM recovery, on your handset. This app will be used for installing a .zip file (the WanamLite firmware) on your phablet.

Also, as we are dealing with a complex operation, a backup procedure is strongly recommended. By using the custom recovery image you will have to wipe the system of your Samsung Galaxy Note 2 LTE, which means that first you have to save the contacts, messages, call logs, internet settings, market apps, EFS and everything else you might need. Also, you can make a Nandroid backup because in this way, if something bad happens or if you will not like the new OS, you will be able to restore the stock firmware.

Finally, for the update procedure, a Windows running computer with internet connection enabled, the phablet and its USB cable will be required. On the same (on the computer and handset) there shouldn’t be any security programs installed (deactivate the antivirus and Firewall protection). Also, for avoiding the unpleasant situations, charge the battery of your Note 2, or make sure that there is at least 60% power left. Enable the USB debugging option on your smartphone and apply the next steps only if you own the LTE variant of the Samsung Galaxy Note 2 (model number N7105); else you will risk in bricking your Android based device.

How to Update Galaxy Note 2 LTE N7105 with Jelly Bean 4.1.2 WanamLite Custom ROM Firmware

  1. Use the link from here and download the update file (the Jelly Bean 4.1.2 WanamLite firmware) on your computer.
  2. Then, connect the handset with the PC via USB cable.
  3. Copy-paste or drag and drop the same file from the computer to your Galaxy Note 2.
  4. Disconnect the device.
  5. Turn off the Galaxy Note 2 LTE and boot into recovery mode.
  6. If you don’t know how to boot into recovery mode, read this guide.
  7. Then, from recovery mode, wipe the system: “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
  8. Select “+++go back+++” and return to the recovery menu.
  9. And from there select “install zip from sd card” and “choose zip from sd card”.
  10. Select the WanamLite ROM and flash it on your Galaxy Note 2.
  11. In the end select “+++go back+++” and “reboot system now”.

If in the end, you will get error messages, or a boot loop, turn off the device; then reboot into recovery mode once more; from there wipe the system as showed above and everything should be fine now. Take note that the first boot will take longer (up to a few minutes) than the usual one, so don’t panic.

If you don’t like the Android 4.1.2 based WanamLite firmware, then use the recovery menu and choose to restore the stock ROM. Be aware as this operation can be performed only if you had previously made a Nandroid backup as recommended.

Now, once the software has been successfully flashed, you might want to customize and optimize the performances of your Galaxy Note 2 LTE. In order to help you out, here are some tips for improving the battery life (this is the most important aspect when talking about a smartphone – the battery life):

  • Deactivate the auto sync option if you don’t need the same; you can enable it when needed.
  • The GPS must be running only when you are using it, else it will drain the battery.
  • Disable auto backups of Gmail account.
  • You can manual set the brightness level (lower the level), or you can choose to automatic adjust the same.
  • Disable the animations effects.
  • Also, disable motion in case you don’t use it.
