The bootloader must be a familiar term with all the android users. If not, we’ve got you covered. It’s just a program code that starts before the operating system (here android) starts loading. A boot manager and Bootstrap loader are few others synonyms to BootLoader.
Why the BootLoader Unlock is Necessary?
Well, you only need to unlock BootLoader of your Android device if you wish to change the ROM with a custom version or firmware. Usually, a device comes with Bootloader locked, so it restricts installation of any such custom ROMs.
Note: You are about to change the OS of the device. Be careful during the whole process or you may end up damaging your device.
So, How to check bootloader status?
The following goes some of the basic ways to unlock your device bootloader.
· Open Dial pad (phone app, used to make calls) of your device.
· Dial “*#*#7378423#*#*” and a new interface would pop up.
· Go to ‘Service Info > Configuration’ and check the Bootloader Lock status.
*if no screen pops up, try the following method.
Method 2 (Requires PC)
· Install ADB & Fastboot on your PC after downloading it from the internet.
· After setup installation, connect your smartphone to your computer via ‘USB in Fastboot Mode’.
· On PC, open the folder where you have extracted the ADB & Fastboot Package. Right click on the folder and then click on ‘Open Command prompt here’.
· Type in “fastboot devices” to cross-check if your smartphone was detected in fastboot mode.
· IF no device is detected, either extraction of the package was not correct or it wasn’t proper. Try reinstalling it after downloading it from some other site.
· Run the following command
“fastboot oem device-info”
You will see the bootloader status of your device and check whether it’s unlocked or not.
