Bootloader
- A general term for a link in the boot-chain that is run each cold-boot which loads the kernel, OS, and related components.
Bootloop
- A word indicating that the device never reaches the end of its boot phase and continually starts over
- Useless when used in describing an error, since there are many points in time during a device boot where it might abort and start over, e.g.
- At the vendor splash logo
- Looping the LineageOS bootanimation (a green circle moving across a line on the screen) endlessly
- Reaching the lock screen or setup screen but immediately restarting
- etc.
Bricked
- A device which cannot be recovered from a fatal failure by any means, leaving it in an unoperable state which is not recoverable by any means outside of OEM repair.
- People often use this word in places where they just mean a Bootloop and their issue can be fixed using either button presses or readily available software tools
Custom ROM
- A (self-)built Android version with changes on top of the AOSP (Android Open Source Project)
Degoogled
- A term describing that an OS has no software parts from, or that attempt to connect to Google
- LineageOS is not explicitly degoogled, we simply don't ship GApps due to licensing
Factory reset
- Despite the name containing "factory", performing such a reset is returning the device into a state "without user modifications", not back to the Stock ROM
Firmware
- Included in the Stock ROM - A layer of software required to allow the OS to interface with the hardware
- Not the same as a Custom ROM or ROM in general but sometimes included in Custom ROM installation packages/instructions
GApps
- Google Apps, usually consisting of the GMS (Google Mobile Services), the Play Store, and a varying amount of the native Apps made by Google (Dialer, Messenger, Calender, etc)
- Google Apps are not preinstalled on LineageOS but can be installed during installation of LineageOS, please see your device's Install guide for more information.
OEM
- Original Equipment Manufacturer, the one who sells and manages software on a give device (e.g. Samsung, Motorola, Google)
Root
- People sometimes wrongfully use this when they mean Unlocking
- Refers to being able to access and modify the contents of read-only partitions via apps or a shell (usually involving a "superuser" (su) binary)
- Some apps "detect" root access on LineageOS (which does not come rooted!) when they actually mean "modified device"
- LineageOS does not offer any rooting solution (despite
adb root) and does not provide support to install any
Stock ROM
- The variant of Android the vendor/OEM shipped on the device from the factory, this applies to OTA (over-the-air) updates issued by the OEM
Unlocked
- There are two types of unlocking when discussing smartphones:
- Carrier unlocking: You can use the device with SIM cards of any carrier
- Bootloader unlocking: You can run unsigned operating systems/kernels. This is the type of unlock you need to install a Custom ROM
- Some carriers allow for (or are obliged to do so by law) removing the SIM lock but still won't allow to unlocking the bootloader
- Some OEMs don't allow unlocking the bootloader
