Bootloader unlocking
Bootloader unlocking is the process of disabling the bootloader security that enforces secure boot during the boot procedure. It can allow advanced customizations, such as installing custom firmware. On smartphones, this can be a custom Android distribution or another mobile operating system. Some bootloaders are not locked at all and some are locked, but can be unlocked with a command, a setting or with assistance from the manufacturer. Some do not include an unlocking method and can only be unlocked through a software exploit.
Bootloader unlocking is also done for mobile forensics purposes, to extract digital evidence from mobile devices, using tools such as Cellebrite UFED.
Unlocking the bootloader allows installing and running unsigned code on a device, including user customized software. Operating outside the manufacturer specification might usually result in voiding any warranties and may make the device susceptible to data theft, as the integrity of the operating system (as intended by the manufacturer) can no longer be guaranteed. On Chromebooks, enabling developer mode makes the system less secure than a standard laptop running Linux. Unlocking the bootloader may require reinitialization, formatting to factory settings, or otherwise lead to data loss on Android and ChromeOS devices. This is due to the fact that some user data is impossible to back up without root permission. This will also lead to certain security apps not working, such as Samsung Knox for which the counter would be stuck at "0x1."
Sascha Segan from PCMag considered a locked bootloader a mistake on the Qualcomm Snapdragon Insiders phone, which is targeted at advanced users.
Unlocking the bootloader is typically a prerequisite of obtaining root access and/or installing a custom ROM.
The bootloaders of Nexus and Pixel devices can be unlocked with fastboot.
When Motorola released a bootloader unlocking tool for the Droid Razr, Verizon removed the tool from their models.
In 2011, Sony Ericsson released an online bootloader unlocking tool. Sony requires the IMEI number to be filled in on their website. For the Asus Transformer Prime TF201, Asus has released a special bootloader unlock tool.
