does not officially support the Samsung Galaxy Tab 3 7.0 (SM-T210R), community developers have historically worked on unofficial ports to keep this vintage hardware functional. Most "work" on this device centers around LineageOS 11 (Android 4.4) or LineageOS 14.1 (Android 7.1). Article: Resurrecting the SM-T210R with LineageOS

There is no official LineageOS support for the SM-T210R. Official development generally focused on variants like the SM-T217S (LTE), which uses a Qualcomm Snapdragon 400 processor—a completely different architecture from the T210R. Attempting to flash ROMs designed for the "lt02ltespr" (T217S) on a T210R will result in installation errors or a bricked device. However, the community has produced unofficial ports: smt210r lineageos work

Quick start checklist (for a developer)

Prepare host with required packages and Java.
repo init & repo sync LineageOS branch.
Place device tree, kernel, and vendor blobs under device/, kernel/, vendor/ repos.
source build/envsetup.sh; lunch appropriate combo.
make -j$(nproc) bacon
Flash with fastboot or sideload payload; test per checklist.
Iterate on logs (adb logcat, dmesg) and patch device/kernel trees.

Build environment

Host: Linux x86_64 (Ubuntu 22.04 / Debian 12 recommended)
Required packages: git, openjdk 11/17 (match LineageOS branch), repo, build-essential, bc, bison, flex, libssl-dev, libncurses5-dev, zip, unzip, python3
LineageOS source: checkout appropriate branch (e.g., lineage-20.0 for Android 13 or lineage-19.1 for Android 12) and initialize with device-specific manifests if available.
Repo sync: full sync with --force-sync for first-time setup.

What is LineageOS?

LineageOS is a free and open-source operating system for smartphones and tablets, based on the Android mobile platform. It's the spiritual successor to CyanogenMod, one of the most popular custom Android ROMs. LineageOS aims to be a stable and feature-rich alternative to the stock operating systems that come with devices, often offering a more recent Android version than the one provided by the device manufacturer.
