Bootloader unlocking: Difference between revisions
Link to our list of phone manufacturers that do not allow bootloader unlocking |
Added a tone notice because there is subjectivity and there is structural problems with the text (headings for example). Also added comments about lack of sources, and changed a source to not source Wikipedia, as that is not allowed (we shouldn't source other wikis) |

Unlocking the bootloader of a smartphone allows the user to install an alternative system on the device, also known as a custom ROM.[1]
Beyond customisation, there are several reasons why a user would want to install an alternative operating system on their phone:
- Superior Privacy: Most custom ROMs do not contain any of the components that send data to the manufacturer, Google, and their partner companies. In some cases, they even contain components that prevent individual apps from doing so, such as /e/'s Advanced Privacy.
- Expanding Device Lifespan: Most custom ROMs are free of bloatware and can thus be used extend the longevity of phones that have become unusable due to the default system growing larger with each manufacturer update. Especially on low-end phones, these updates usually end up exhausting the built-in storage after sometimes as little as two years. This renders the devices slow and unstable and leaves no room for user data. Custom ROMs are typically much smaller than the manufacturer software. Consequently, many old phones can run even faster with a custom ROM than they were when new, thus often more than doubling their useful lifespan.
- Security Updates after device is abandoned by manufacturer: Low-end devices usually receive only a few years or even months of security updates. Since most custom ROMs are built by the open source community, installing one of these custom ROMs allows users to receive security updates for the Android system and default components like web browser engines and PDF readers much longer than with the manufacturer's OS.
Unlocking the bootloader is only possible on some, but not all Android devices. Apple has measures in place that prevent users from installing third party operating systems on iPhones and iPads.
Features
On a default Android system there is the deep integration with Google Play Services. This is a system process that requires access to files, contacts, storage, call logs, SMS messages, location, camera and microphone so that basic system apps are able to function.[2] Alternative systems avoid this process entirely, or use privacy preserving workaround.[3]
Alternative Android-based Operating Systems
These include, but are not limited to:
- AOSP (Android Open Source Project) , also known as "stock" Android.[4][5]
