How to unlock Bootloader from your Android

Take a shortcut

Introduction

Each device has its own hardware, with a motherboard that requires its own bootloader. Therefore, a different procedure is required for each device according to the manufacturer. I will talk below the major smartphone brands, using applications that do not require advanced knowledge and that will make your life easier. For more basic information about Bootloader function, please visit the article below:

Attention: Neither I nor AndroidPIT can be held responsible for damages incurred during proceedings described in this article. We recommend backing up all files on your device before performing the process.

Each method described (with the exception of HTC and Sony devices) requires root permissions enabled on your device. To learn how to get them, check out the articles below:

Samsung

Most Samsung devices already have an unlocked Bootloader. However, there are exceptions, such as the Galaxy S3 connected US carrier Verizon. In the rare case you have one of these devices and want to unlock Bootloader, just download and install the EZ-Unlock app and click the Unlock button.

EZ-Unlock works only for devices manufactured before 2012.

note: EZ-Unlock only works for devices manufactured before 2012. Therefore, if your device does not meet this requirement, it is not compatible and may cause problems. Also, it is possible that the script for your device is up to date, and you will have to create it.

Remember that this app has already caused many problems among Samsung users. I suggest that before using it, you should check to see if other owners have been successful with the process, otherwise use the traditional Bootloader unlocking system via SDK.
