Upgrade Samsung Galaxy Note 3 N9005

Everyone’s too hyped up with the release of the Android 5.0 Laptop, and as such, developers have been working hard to provide users with Factory Images or Android 5.0 Lollipop based ROMs. Some of the devices that have already received Factory Images are Nexus ones, the Moto X, and the LG G3, among others. Meanwhile, other devices have been receiving the OS update through CyanogenMod (CM) 12. As expected, the Android 5.0 Lollipop from custom ROMs come with bugs, but fortunately, the one on Samsung Galaxy Note 3 are only experiencing unexpected reboots.




This article will provide you with a step by step guide to install Android 5.0 Lollipop on your Samsung Galaxy Note 3 using CyanogenMod 12. As a Custom ROM release, some things to expect are the following:

  • Unexpected reboots
  • Interrupted performance of Audio Codec on playback
  • Slight glitches in the Home button
  • Video Recording cannot function on the device’s Stock Camera App




Before beginning the installation process, here are some notes that you have to consider:

  • This step by step guide will only work for Samsung Galaxy Note 3. If you are note sure about your device model, you may check it by going to your Settings menu and clicking ‘About Device’. Using this guide for another device model may cause bricking, so if you are not a Galaxy Note 3 user, do not proceed.
  • Your remaining battery percentage should not be less than 60 percent. This will prevent you from having power issues while the installation is ongoing, and therefore will prevent soft bricking of your device.
  • Backup all of your data and files to avoid losing them, including your contacts, messages, call logs, and media files. This will ensure that you will always have a copy of your data and files. If your device is already rooted, you may use Titanium Backup. If you already have an installed TWRP or CWM custom recovery, you may use Nandroid Backup.
  • Also backup your mobile’s EFS
  • Your Samsung Galaxy Note 3 should be rooted
  • You need to flash TWRP or CWM custom recovery
  • Download CyanogenMod 12
  • Download Android 5.0 GApps

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
