What is bootloader Android?

Android bootloader code is a (sort of software), which has the mission to perform certain tasks, such as loading the kernel (core operating system), debugging, etc.
Android bootloader is locked on the base to protect the phone against the installation of malicious code.

How to install updates with locked bootloader?

OTA updates come directly from producers and therefore are digitally signed. With a valid signature, they can pass verification and can even install the bootloader locked.

Why is unlocked bootloader?

Naturally not everyone has to unlock the bootloader phone, but only those who want to make Root, install other recovery or another rom.
If you do not need root, another rom or other recovery does not need to unlock the bootloader.

How to unlock the bootloader?

The process itself, unlocking the bootloader is simple. Greater the preparatory work, where we need to ensure that we have the USB drivers installed and your phone is recognized, then we must install the Android ADB. Below are links to the universal USB driver for Minimal ADB.

Tools for unlocking bootloader.

1. Universal Windows ADB Driver
2. Minimal ADB and Fastboot
After installing the tools we move on phone and Developer options Unlock tick OEM (from android 5.0 here). After that restart the phone to fastboot, where we give the command fastboot oem unlock. Will appear on the screen two buttons YES and NO, we will choose YES to unlock the bootloader (sailing with the volume keys and confirm with power).
CAREFUL
Before unlocking the bootloader, you must back up because the phone will reset to factory settings.

Tutorials recommended for backup:

1. Backup games and applications - Move to a different phone games and applications without loss of data Helium
2. Backup calls and SMS - Espionage or call log and sms backup for android phones
3. Automatic backup of pictures and movies - SyncMate Wireless, cloud backup and personal in my PC

What about recovery and the root?

    • Some manufacturers and service providers (Vodafone, Orange, etc.) will only use rum to their website, they have installed some tools for data collection.
      Therefore, I recommend phones OnePlus.
      OnePlus is probably the only manufacturer that lets you do Root, to install other ROMs, kernels, etc., during which you are covered by the warranty.

      • Hello i have a samsung galaxy Cristi grand 2 and i have placed a custom recovery and custom rom without bootloader unlock. I used an app rootare and used another ablicatie calling rot permissions to install CyanogenMod recovery and now we 13 but I bootloader unlocked, okay?

      • No, it's wrong what you say Alcatel lets me unlock the bootloader to root and install another recovery. So? Stop talking if you don't know at OnePlus Yes, they leave you, hey, but they also leave you at Alcatel. At least the Alcatel 1s leaves you. So???

  • CRIS few tutorials since the sound recording is very low should greatly increased volume from speakers or headphones you can hear better. Find some settings best or try to record something else

    • Ok, I'll make the changes. I went on the sound quality, not volume. If you seek a higher volume, I offer it to you.

  • Cristi, you can make a toturial that show us how we can put two operating systems on a phone? I recently purchased a OnePlus 3 and I want to see how. Thank you!

  • YES ...... we want more …… root, recovery, rom .... and I would have another question: I can still lock the bootloader if I want this. Thanks for the tutorial. Note 10.

    • The bootloader can lock back in without any problems. The command is "fastboot oem lock"
