Why to unlock Android Bootloader
Why to unlock Android Bootloader
In this article we will tell you why to unlock Android Bootloader. Here’s the complete detail.
What does Android Bootloader mean?
Bootloader is a sort of programming code that must be executed just before any OS begin to run. Every Android-based device has its own kind of Bootloader that orders and instructs its OS kernel to boot routinely or we can say ‘Normal Booting’.
Android is basically an Operating System based upon Linux. Android OS is primarily designed for touchscreen based mobile devices, like Tablet PCs and Smartphones. Technically, Android is an OTA open-source application stack developed from mobile phones, portables and handhelds.
But it should be noted here that since an Android is an open source operating system and is bundled on an array of different hardware, therefore we find different classes of Bootloader on different kinds of hardware.
Why Android Bootloader is locked?
Although Android is an open source operating system, still you will find a locked Bootloader on the device. This is due to the reason that the device manufacturers want to keep the user on their particular Android OS version exclusively designed for that device. They would not like to see the user playing around with their OS’s security.
When to unlock Android Bootloader?
When someone desires to flash the stock ROM of his device for installing another Custom ROM, flash Recovery image files, Kernel, or when he wants to perform rooting on his Android device, then his first step is to unlock the device Bootloader. Without unlocking Bootloader on an Android device, one can’t install or flash anything on his Android device or even he is unable to perform rooting.
Disclaimer for unlocking Android Bootloader
Due to unlocking of Bootloader, your Android device may lose its official Warranty and while performing unlocking of Bootloader no one will be responsible if anything occurs to your Android device, so continue at your own risk.
Pre-Requisites of unlocking Android Bootloader
- For successful completion of unlocking Bootloader process, you must charge your Android device up to a minimum of 75% – 85% battery.
- You must take a back-up of all your personnel items and other impotent data, such as Call Logs, SMS, Contacts, Audios, Images, Videos, APN (Access Point Names) settings, Bookmarks, MMS settings, on your Android device.
- Please ensure that all your security suites, like firewall and antivirus, on your Android device as well as on computer must be disabled.
- You must enable USB Debugging mode on your Android device. Just follow, Settings –> Applications –> Development –> USB debugging. There select the USB Debugging icon.
We hope now you know “Why to unlock Android Bootloader“.
