I like Samsung Android devices because they have unlocked bootloader. Same apply to Samsung Galaxy Note II. So that you can modify it with whatever you prefer like install custom kernel, ROM, theme, firmware… However, install these unofficial stuffs will void warranty ~ custom binary download will increase, current binary and system status to custom in Samsung Galaxy Note 2 Odin Download Mode. No worry, you can always restore to stock Samsung Galaxy Note 2 to recover warranty back. Reset custom binary download to No, current binary to Samsung Official and system status to Official. And Device status from Modified to Normal (Settings – About device – Status). It will be like a brand new Samsung Galaxy Note 2 like you turn on it for the very first time. How to do so? Please refer to below step by step video guide to know more…
