How To Unlock Bootloader On Infinix Smartphone And Relock It Back

What is a Bootloader on Android?

A Bootloader on any Android device is software or a set of programs that actually commands or helps the device to boot into the operating system or the recovery mode. It basically depends on the user in which mode the device should start or power on. To understand it better, a Bootloader is a vendor-specific image file that loads up the device kernel and allows the hardware to run the system or recovery.

A locked device bootloader always verifies the secure boot state of the device and recognizes whether the device is trying to boot up the signed images from the manufacturer. That means if, in case, you’re trying to flash or boot any third-party file on a locked bootloader, it won’t work.

It’s one of the security measures that has been provided by each Android device manufacturer to protect the system and its partitions from external items that may affect the system files. Therefore, every Android smartphone manufacturer offers a locked bootloader state to their devices out of the box. But you can start customizing on Android by unlocking the bootloader very easily.

Advantages of Bootloader Unlocking

There are a couple of benefits of having an unlocked bootloader on your Infinix device, such as you’ll be able to customize your handset from the system level fully. Additionally, you can flash any third-party firmware (aftermarket firmware) instead of using the stock ROM or XOS skin.

Meanwhile, you can also enable root access on your Infinix handset, and then you’ll be able to install the Xposed Modules or Magisk Modules. The best part is that you can use rooted apps on your device after rooting, which will offer you some advanced level performance or customizations that you won’t get on the non-rooted device.

Interested users can also install a custom recovery mode rather than using the stock recovery, which will offer various options to go through. Another thing we should mention is that you can easily improve battery life, overclock hardware performance, and uninstall bloatware or system applications using root access.

Disadvantages of Unlocking the Bootloader

Well, if there are good things, then it should have bad things too, so the Infinix device users may also experience some unexpected issues. Regarding the disadvantages of bootloader unlocking, your device may get bricked or stuck into the boot loop issue if you don’t follow the steps and requirements properly.

Alternatively, some unlucky users may find that their handset becomes much slower than before. At the same time, unlocking the bootloader should void the official warranty on the device from the manufacturer (if applicable). The handset may start behaving weirdly if something conflicts with the system files because a device with an unlocked bootloader is more vulnerable to security risks or malware attacks.
