Whether you own an Android Smartphone or a tablet device, whether you are a noob, basic or advanced user, you need to be aware of certain things about your device. Booting your device into Odin/download/fastboot/ bootloader or recovery mode (stock or recovery) is a piece of knowledge you must have.

An Android device is a myth to the unknown when I got my first Android smartphone (LG Optimus One – an excellent and rare piece of work by LG), I was astounded to find out that in how many different modes it could boot. I know it sounds like a complete layman, but back then it actually was so. With time, not just the hardware and software has been revised, but also the resources, which act as a great source of knowledge for learners.

Today, almost 95% of the how-to or guide articles require you to boot Android devices into Fastboot mode, Recovery mode, Download mode, or Flash mode for the procedure to carry out. Rebooting into these modes can either be carried out universally for any Android device by the unified ADB commands listed below.

  • Recovery Mode:
adb reboot recovery
  • Fastboot/Bootloader Mode:
adb reboot bootloader



But then…

It’s not always necessary that you’ll find a PC/Laptop nearby to perform this action. So, your respective OEM has already bothered to provide you with an alternative, you can do it by pressing a few key combinations while your phone is completely turned off. Generally, we provide these combinations in every article wherever necessary, but it is always a nice idea to accumulate everything in one spot.

With this end at the back of our mind, we bring together the keys to boot your Android device in download/fastboot/bootloader and recovery mode at a single spot. We aim to make this article a handbook for such purposes and therefore we have made a beginning with most recognized and popular brands like Samsung, LG, Motorola, HTC, SONY, Asus, etc. and we plan to add more brands and devices, making this article all-inclusive and, at the same time, an exclusive presentation from Droidviews.

Now, before you proceed any further, it is necessary to install ADB and Fastboot on your PC. Also, enable USB debugging on your device. To install ADB and fastboot on your PC, follow the links below depending upon the OS you use on your PC.

Disclaimer:
Please note that you will be able to
boot your device in Custom Recovery only if it is rooted. We don’t hold any
responsibility for any damaged devices. Understand the risks involved and
proceed only then.

Also, this guide is progressive and will become lengthy with time, depending upon the number of devices we will add. Some specific device could actually have a different key combination or some device could behave differently, if you have any trouble with the following tutorial, or if you have pointed out a non-working key-combo, kindly drop a comment at the end of this article and we will be happy to help you.
