Booting into the download mode and recovery mode are the two words that you must have heard but some of you may not be much familiar how to actually get into these modes on the Samsung Galaxy Devices, whether the Galaxy smartphones or the Galaxy Tabs. While some of you may not even know what are these modes and why do we need to boot into these modes, let me explain you guys a little first.
Download Mode: Download Mode is also known as Odin3 mode, the mode allows you to flash stock firmwares, bootloader, modem, pit files, sometimes the root package files or custom recovery files using your PC. To do so, a light tool is used named as Odin3, that’s why the mode is also known as Odin3 mode. To use the download mode or flash files using your PC, you simply need to boot into download mode, connect your device to your PC and flash your desired file using Odin3. Full guide about Odin can be found here.
Recovery Mode: Recovery mode is of much help when it comes to flashing zip files directly on your phone, but that’s most of the times possible only by having a custom recovery installed on your phone. Using the recovery mode you can clear your phone’s cache, wipe factory data, wipe dalvik cache. In case you have a custom recovery installed on your phone, it let’s you make a nandroid backup, let’s you flash zip files like mods, custom roms etc, custom recoveries also allow you to restore your system if you have backed it up.
Sometimes, what happens is, you are struck in the bootloop, or your phone doesn’t respond. In the case you can either access the download mode or the recovery mode. Wiping cache and dalvik cache may let you get rid of the problems, but just in case non of these works, booting into download mode and flashing a stock firmware will definitely help you.
