How To Check Bootloader Is Unlocked

This article tells you how to Check Bootloader Is Unlocked. If you use Android, you may have heard of a term called “bootloader.” In simple terms, “bootloader” is a piece of code that runs before any operating system does. In the case of Android devices, many manufacturers ship their smartphones with a locked bootloader.

This makes it nearly impossible to install a custom ROM or firmware on those devices, so you have to unlock the stock bootloader before you can flash a custom ROM or firmware on Android. There are some things that the Android OS can do that other operating systems can’t. One of the best things about Android phones and tablets is that you can unlock the bootloader.

You can “root” the device with the bootloader. This gives you almost full control over your phone. That’s because you can change almost everything on a rooted phone. We mentioned below are the ways to fix Check Bootloader Is Unlocked.

How To Check Bootloader Is Unlocked on PC

Use an ADB and fastboot tool on your computer to check the status of your bootloader. Until recently, you had to download the whole Software Development Kit (SDK) to get to ADB and fastboot. But now you can buy this small tool on its own.

Checking the Status

Now that everything is set up, you can check the status of your bootloader using the Command Prompt. Here’s what you should do:

1. Enter the ‘./adb devices’ command into the Command Prompt to check if ADB can locate your device. This should list your phone.
2. Execute the ‘./adb bootloader’ command to boot into bootloader.
3. Once you are in the bootloader, type the ‘fastboot devices’ command in the Command Prompt and execute it. If it lists a code, that means that the system can detect your phone.
4. Enter the ‘fastboot oem device-info’ command and run it. It should list some device data, including the bootloader information.
5. Look for ‘Device Unlocked’ from the info.
6. If it says ‘true’ next to it, it means that your device is unlocked. If it says ‘false,’ it means that that it’s still locked.

Setting Up the Command Prompt

1. Locate the path to the ADB and fastboot folder.
2. Click on the Start Menu and type ‘cmd’ until the Command Prompt icon appears.
3. Type the path to the ADB and fastboot folder in your Command Prompt. For example:
   C:UsersUsernameDownloadsADB and fastboot

Turning on the Fastboot Mode

1. Turn your Android phone off.
2. Hold the Volume Down and Power/Unlock buttons at the same time until the phone turns on again.
3. Release the Power button when it turns on, but keep holding the Volume Down key until you see the bootloader menu. It should show the little Android bot lying on its back against a dark background, with text under it.
4. Connect the computer and your phone with a data cable.

How To Check Bootloader Is Unlocked on Android Device

On many Android phones, you can dial a code to find out if the bootloader is unlocked. If this doesn’t work, you can always use the second, longer method. If you want to check the status of your phone’s bootloader right from your phone, you should:

1. Unlock your Android phone.
2. Open the Phone app or the Dialer.
3. Enter the code: *#*#7378423*#*#
4. This should automatically open a new window.
5. Tap the Service info.
6. Open Configuration.
7. You should see one of the two messages:
   – Bootloader Unlocked Allowed – Yes
   – Bootloader Unlocked – Yes

If you’ve tried all of these solutions and you’re still having the same problem in your devices, you should go to their official Android support website for more information.
