If you are an Android device user, then you possibly would have heard the term ‘bootloader’ for sure. However, if you still are unaware due to any reason, then you should know that bootloader is a code which executes before any operating system starts to run in any device. Most of the times, if you are an Android lover who even likes to customize his device according to his will, then there is very likely that you would want to unlock the bootloader of your Android device. However, if you are looking for a way to check bootloader status in any Android device, then here is a solution for you.
Most of the times, the manufacturers would just sell their devices with the bootloader locked, which doesn’t let you install a custom ROM or any other software which you aren’t officially allowed to install or install additional firmware on your devices. This means that doing anything like installing new firmware, new custom ROM or flashing anything new, you actually would have to unlock the bootloader of your current Android device.
However, yes, the thing about unlocking bootloader of any Android device is that once you unlock the bootloader, there is no going back and well, you would even void the warranty of your Android device. So, please be sure about what you are actually doing.
For a few devices, we have already mentioned guides and well, you can check them out here.
Now, the main thing:
How to check if your bootloader is locked or unlocked?
We are providing two methods which are applicable for almost every new and old Android device. Better try them out:
Method 1: Without a PC
- This method is an easy method which eventually doesn’t require a PC. This means that you can easily check the bootloader status of any android device which you use. Just follow these steps:
Open your Android device’s dialer which you use to make calls. - Now, type the following code in the dialer and you would notice that it automatically opens in a new window in your device.
*#*#7378423#*#*
3. However, if nothing happens, try the second method given below.
4. Now, in that window, go to Service Info > Configuration and see if there are the following options:
Bootloader unlock allowed - Yes >> This means that your Bootloader is Locked
Bootloader Unlocked - Yes >> This means that your Bootloader is unlocked
This is it. Now as you are confirmed, you can begin your further customization as you like. However, if this method didn’t work for you, we have something else for you.
Method 2: Using a PC
You are going to need your PC or laptop for this purpose. Keep it open and:
- First of all, download and install adb & fastboot package & drivers in your system which you can get in Google easily by searching for them.
- Now, install adb & fastboot on your system and connect your device to your laptop or PC via a USB Cable in fastboot mode.
- In the folder where you downloaded and extracted adb & fastboot, and press Shift key on your keyboard and right click in the folder to select the option “Open Command Prompt here”.
- Now, you will see that a command prompt window would be opened.
- Now, type the following command in the command window to check if your device was detected in fastboot.

6. If you don’t get your device, it means that it wasn’t detected as the drivers were not installed properly in your PC or laptop. Try re-installing them in your PC.
7. Now, run the following command in the command prompt window to check the status of your device’s bootloader:
fastboot oem device-info
