An encrypted bootloader is usually the source of contention among those who like a manufacturer's hardware and wish to mess with it. LG, Samsung, Motorola, HTC, and other manufacturers frequently ship devices with encrypted and locked bootloaders. It's often done because the carrier who had the handset manufactured for them wishes it locked up. This provides an additional degree of security for end customers but also makes it difficult to update the handset's firmware.

Let's have a look at what Android bootloader mode and what you can do with it.

Part 1. About Android Bootloader

1. What Does Restart Bootloader Mean

The bootloader is a set of instructions or utility software that assists the operating system in configuring what to load and the order in which it loads it. When the bootloader is correctly rebooted, it unlocks the appropriate parameters and allows the user to customize the stock operating system.

A bootloader is a tool that you use when your device does not start properly, and you require a software tool to assist you in resolving the underlying issues and making the device work properly. The bootloader can also be used to reset a device that cannot be reset in any other way.

The bootloader provides you with the following utilities. If you want to accomplish any of the following, you can use the bootloader:

Restart a device that any other technique cannot restart.
Manually flash the ROM of your device.
Wiping the cache partition.

2. How to Access Android's Bootloader?

Getting into the bootloader isn't something you'll need to do very often, but it's always important to know how to do it just in case. Below we will go through how to access Bootloader Directly from the Device.

To enter the bootloader without using a computer, first power down the device fully. The steps below should work on 90% of the target devices; however, you may need to look for additional instructions for your individual handset if you are having problems.

Let’s get started with accessing Android bootloaders for different Android devices.

Nexus and Developer Devices

Hold down the volume and power buttons at the same time. Release them when the Google splash screen shows.

Samsung Devices

Samsung smartphones do not have a typical bootloader, but rather what the firm refers to as "Download mode." To access it, hold down the volume, power, and home buttons until the Samsung logo appears, then release. However, be aware that it is essentially worthless without a computer. To leave download mode, press and hold the home, power, and volume keys simultaneously.

LG Devices

Hold down the volume and power buttons until the LG logo displays, then let go. If this doesn't work, try releasing the power and volume down buttons for a second when the LG logo displays, then repressing them till the bootloader appears.

HTC Devices

Press and hold down the volume, then power up the device while holding down the volume key. The bootloader is called "fastboot mode" on HTC devices.

Motorola Devices

Press the volume and power buttons and hold them down for a few seconds until the logo appears and the device enters the bootloader mode.

The bootloader can take a few seconds with all of these commands to show up after the keys are released. You can carry on whatever you want to do when the device enters the bootloader mode.
