How To Enter Samsung Recovery/Download Mode
If you just start to learn about flashing Samsung device, you might be confused about the terms like recovery mode, download mode. This post is going to explain what exactly recovery/download mode are and how to enter Samsung recovery/download mode mode.
What are Recovery/ Download Mode
Recovery is an independent, lightweight runtime environment that's included on a separate partition from the main Android OS on all Android devices. By entering recovery mode, you can factory reset the device, delete the cache partition, or apply software updates. If your Samsung phone comes across some serious problems, such as having a virus, software being corrupted, the screen being frozen, recovery mode can help to fix these problems.
Download mode, also known as Odin mode, is a mode that is more often seen in Samsung devices. After entering download mode, users can connect their Samsung phone with PC and flash ROMs and kernels using software like Odin download tool or any other software. These ROMs and kernels might be official firmware builds, ROMs, rooting files and more.
Both recovery mode and download mode allow users to flash ROM on Samsung phone, but are performed in different ways. Flashing ROM via recovery mode needs ROM in zip format and don't need to connect to computer. On the other hand, if flashing ROM by entering download mode, you have to connect the Samsung phone to computer and use Odin to perform the flashing with ROM file *tar or *.tar.md5 format.
