The Samsung Galaxy Tab 3 7.0 (SM-T210R) is an older device that officially stopped receiving updates at Android 4.4.2 KitKat. While official LineageOS support for this specific model has ceased, community-driven projects have attempted to bring newer versions of Android to the hardware. Current State of LineageOS on SM-T210R
Official LineageOS support for the SM-T210R is currently non-existent. The device was largely dropped from modern development due to its limited 1GB of RAM and the lack of publicly released source code for its Marvell PXA986 chipset.
Unofficial Builds: There are unofficial "Lollipop" (Android 5.0) and "KitKat" ports available on enthusiast forums like XDA Developers, though these often suffer from stability issues or hardware bugs (e.g., camera or GPS not working).
Performance Reality: Even if a build is successfully flashed, the aging hardware struggles with modern applications. Some experts recommend alternative devices, such as a last-gen Amazon Fire 10, for a smoother experience. General Installation Workflow
If you find a compatible unofficial ROM, the installation typically follows these steps:
Preparation: Install necessary Samsung USB drivers and platform tools (ADB/Fastboot) on your computer. smt210r lineageos work
Custom Recovery: You must flash a custom recovery like TWRP using tools like Odin to bypass the stock Samsung recovery.
Wiping Data: Boot into TWRP and perform an Advanced Wipe of the Dalvik/ART Cache, System, Data, and Cache.
Flashing: Install the LineageOS .zip file followed by an optional GApps (Google Apps) package if you require the Play Store. Common Troubleshooting
Bootloops: Often caused by incompatible kernels or failing to wipe partitions correctly. Holding Power + Volume Down can force a restart out of a "Kernel Panic" screen.
Lag: Given the 1GB RAM, users should avoid heavy GApps packages and stick to "Pico" or "Nano" versions to save system resources. Special Boot Modes Recovery Mode: Home + Volume Up + Power. Download/Odin Mode: Home + Volume Down + Power. The Samsung Galaxy Tab 3 7
First, a critical clarification:
The SM-T210R is actually the Samsung Galaxy Tab 3 7.0 (released 2013).
The Galaxy Tab A 10.1 (2019) has model numbers like SM-T510/T515.
If you meant the SM-T210R (Tab 3 7.0):
If you actually meant the SM-T510/T515 (Tab A 10.1 2019) :
Final answer for SM-T210R: There is no current, stable, or officially supported LineageOS for that device. Find an old XDA thread if you want to experiment, but expect poor stability.

Here’s a detailed write-up about the status and process of getting LineageOS working on the Samsung Galaxy Tab S6 Lite (SM-T210R).
github.com/LineageOS/android_device_samsung_gta4xlwifi@linuxandria, @t-abt (credits for kernel work)Some developers have attempted to port Android Go (Android 8.1 Go Edition) to the smt210r, as it is designed for 1GB RAM devices. Unfortunately, due to the Exynos GPU blob issue, these attempts have stalled. As of 2026, no active development exists on XDA or GitHub for this device.

Working on an unofficial LineageOS build for the Samsung SM-T210R (Tab A 2017). The hardware is showing its age, but the kernel is booting!
Current blocker: Audio HAL issues. Once that's sorted, I'll drop a link for testers. #LineageOS #SM-T210R #AndroidDev #OpenSource
If you get LineageOS booted on the SM-T210R, the "work" shifts from installation to maintenance. Common issues reported by users of unofficial builds include:
Permissive rather than Enforcing to force compatibility. This lowers security but is often necessary to get the camera or audio working.
