Regarding the history, we’re not happy, but We’ll share with you several clever ideas for unlocking phones and computers user accounts, hidden storage, and android, iOS mobile operating system, Nokia phones in the coming days! Read on for the article and come back in the next few days.

Unlocking your bootloader is the first step towards rooting your phone and installing custom ROMs. It’s also the place where now people run into trouble - not because it’s particularly difficult, but because phone manufacturers and network carriers don’t want - or don’t trust - you to unlock it. It's not unlike Android rooting, another superuser practice that manufacturers discourage.

When you root an Android phone, you give yourself superuser access. A superuser is an administrator who has access to more features and functions of a system and can make changes to it beyond its standard behavior. This capability grants more access to the operating system, which means more power over how the device works. It also brings the potential to damage how the device operates.

Android is an open source operating system, although the Google fork of it contains a lot of Google-specific services baked in. Because the core of Android is open source, anyone can build on and modify it. Now of the time, device manufacturers modify the OS to create custom Android versions for their phones, add features, and create a polished experience for users. Part of that includes imposing their own rules and restrictions on their custom Android builds.

Phone service carriers and device manufacturers such as Samsung, LG, Huawei, Xiaomi, and others, put modifications and restrictions on their phone products.

How to Enable OEM unlocking

Before you can actually unlock your phone, you need to enable the OEM unlocking developer feature in Android.

1. Open the Settings app on your device.

2. Scroll down, and select System settings.

3. Under System settings, locate and select About phone.

4. Near the bottom of the screen, you’ll see the Build number. Tap it seven times to enable the developer options. When you reach the seventh time, you may be prompted for your password to confirm.

5. Return to the System settings.

6. Locate and select Developer options.

7. Find the OEM unlocking option, and toggle the switch on.

8. Scroll down and locate Android debugging. Toggle the switch on.

How to Install Android Tools

Enabling OEM unlocking only makes it possible to unlock the device. In order to actually unlock it, you’re going to need a couple of Android developer tools from Google. These are freely available, and they’re simple to use.

Windows

1. Download the latest Android tools ZIP for Windows.

2. Unpack the ZIP file into a convenient folder. This is the folder you will run the tools out of, so it should be fairly easy to access.

3. Right click in the folder window containing the extracted files. When the menu pops up, select Open command window here.

UBUNTU/DEBIAN LINUX

1. Open a terminal window.

5. Use ‘sudo’ to get root privileges, and use the following command to install the Android tools.

$ sudo apt install android-tools-adb android-tools-fastboot

How to Unlock With Fastboot

You’re ready to unlock your phone’s bootloader with the Fastboot tool that you just downloaded. Before you go any further, you should see if your phone requires a code from the manufacturer to unlock it. Here are the instructions for several major phone manufacturers:

LG

HTC

Motorola

Sony

Samsung – Only international Samsung phones with an Exynos processor can be unlocked.

Google phones can all be unlocked by default, unless you purchased them from a major carrier.

1. Plug your phone into your computer with its USB cable.

2. In the terminal (or Command Prompt), run the following command to connect your phone.

adb devices

You’ll see a message requesting access on your phone. Check the box to always allow the connection, and confirm.

3. Run the following command to reboot your phone into the bootloader.

adb reboot bootloader

4. Wait for your phone to reboot. You’re now ready to unlock with Fastboot. On newer devices and Google devices, run the following command:

fastboot flashing unlock

On devices that require a code—or, possibly, some older devices—run this command:

fastboot oem unlock - code

Omit the code, if you don’t need one.

You may be asked to confirm. Do so.

5. After your see a confirmation message that your bootloader is unlocked, you can reboot it with Fastboot.

fastboot reboot

6. As your phone reboots, you’ll probably see a warning that your bootloader is unlocked, and that it isn't secure. Continue booting. Your bootloader is unlocked, and you’re ready to continue on to flashing custom recovery and rooting your device.
