The Ultimate Guide to Unlock Bootloader on (Almost) Any Android Device

Samsung, HTC, Motorola, Nexus, LG and almost any Android smartphone vendor provide their smartphone devices to consumers with the lock bootloader, these globally top phone manufacturers allow consumers to easily unlock the bootloader on their device and install custom roms, custom recovery and get root access.

Bootloader unlocking is not recommended by phone vendors because the device’s warranty is lost from that day you unlock it. If you have a bill for your phone, check the billing date and make sure your warranty is over. If not, I do not personally recommend unlocking your device until the warranty overs.
