How to Access Bootloader or Recovery mode in Android Phones



Hello friends !!!!
I am back with my new topic which is “How to Access Boot loader or recovery mode in Android Phones”. There are occasions when getting into Android’s boot loader or recovery, systems is necessary perhaps the OS is having issues and you need to factory reset, or maybe you want to Boot your phone. Fortunately, booting into the boot loader and recovery mode both are very simple. Here’s we will show you how it can be done. Before going to topic directly let’s talk about some basic things about it.
What is a bootloader ???
In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. This is one reason that all Android phones have different Custom ROMS developed due to high variance of processing hardware present on the device. The Devices running iOS somewhat share the same hardware spaces and hence you don’t see much variance in their bootloaders.
How to Access Android’s Boot loader ?
Booting into the bootloader is not necessarily something you’ll need to do often, but it’s definitely something that’s good to know how to do just in case. There are two different ways to go about accessing the boot loader: directly from the device or using commands on your PC. Let’s cover the former first.


Method 1: Accessing the Boot loader Directly from the Device
To get into the bootloader without using a computer, the first thing you’ll want to do is completely power the device down. The following instructions should work on 90% of the intended devices, but if for some reason you’re having issues, you may have to look up further instructions for your specific handset:
Nexus and Developer Devices: Press and hold the volume down and power buttons at the same time. When the Google splash screen appears, release them.
Samsung Devices: Samsung devices don’t have a traditional boot loader, but something the company calls “Download mode.” To access it, press and hold the volume down, power, and home buttons until the Samsung logo shows up, then release. Be warned, however, it’s basically useless without a computer. Press and hold home, power, and both volume buttons to exit download mode.
LG Devices: Press and hold the volume down and power buttons until the LG logo appears, then release them. If this doesn’t work, you may have to release the power and volume down buttons for a second when the LG logo appears, then re-press them until the boot loader shows up.
HTC Devices: Press and hold the volume down button, then power up the device while keeping the volume down key pressed. The boot loader on HTC devices is referred to as “fast boot mode.”
Motorola Devices: Press and hold the volume down and power buttons for a few seconds.
Yu Yureka Devices : Press and hold volume up and power button for few second
Gionee Devices: Press and hold volume up and power button for few second

With all the above commands, the boot loader may take a few seconds to show up after you release the keys. When it does, you can continue with whatever it is you need to do. If you have device which have not
mention in this following list than for best result use google by typing “Recovery mode keys for My Phone”.
Method 2: Accessing the Boot loader with ADB

have technical knowledge. Anyone can Unlock Bootloader Of Any Android just by issuing few fastboot commands. So just follow the guide to get your device’s bootloader unlocked.
