A dedicated group of maintainers on XDA Developers and GitHub have been working on LineageOS 20 (Android 13) and LineageOS 21 (Android 14) for the SM-T210R.
Current stable build: Unofficial LineageOS 20 (Android 13)
Experimental: LineageOS 21 (Android 14) – limited hardware acceleration issues.
If you're looking for a review or specifics about running LineageOS on an "smt210r" device, I recommend:
This should give you a better understanding of what to expect and help you make an informed decision about whether to install LineageOS on your device.
Installing LineageOS on the Samsung Galaxy Tab 3 7.0 (SM-T210R) is possible, but it requires using unofficial builds since this device (codenamed lt02wifi) is not officially supported by the LineageOS team. Important Prerequisites Battery: Charge to at least 70%.
Backup: Back up all data; this process will wipe your device. Drivers: Install Samsung USB Drivers on your PC. Hardware: A high-quality micro-USB cable. Step 1: Install TWRP Recovery
To flash custom ROMs, you must replace the stock recovery with TWRP.
Download: Get the SM-T210R compatible TWRP recovery (.tar file) and Odin3.
Download Mode: Power off the tablet. Press and hold Volume Down + Home + Power until the warning screen appears, then press Volume Up. Flash: Open Odin on your PC and connect the tablet. Click the AP button and select the TWRP .tar file. In the "Options" tab, uncheck Auto-Reboot. Click Start.
Once "PASS" appears, manually reboot into recovery by holding Volume Up + Home + Power. Step 2: Wipe the Device Once inside TWRP: Go to Wipe > Advanced Wipe. Select Dalvik / ART Cache, System, Data, and Cache.
Swipe to Wipe. (Do NOT wipe Internal Storage if your ROM file is saved there). Step 3: Install LineageOS
Due to the age of the Marvell PXA986 processor, the most stable version is usually LineageOS 11 (Android 4.4.4). smt210r lineageos work
Download: Find the unofficial SM-T210R ROM zip on XDA Developers.
Transfer: Move the ROM zip (and optional GApps) to a microSD card or the tablet's internal storage.
Flash ROM: In TWRP, tap Install, select the LineageOS zip, and Swipe to Confirm Flash.
Flash GApps (Optional): If you want the Play Store, flash a "Pico" or "Nano" OpenGApps package immediately after the ROM. Step 4: Final Reboot Go back to the main menu and select Reboot > System. The first boot can take 5–10 minutes. Current Status & Compatibility
Hardware Limitations: Because the SM-T210R uses a Marvell chipset (which lacks open-source documentation), newer versions of LineageOS (14.1+) are often "work-in-progress" with bugs like broken cameras or hardware acceleration issues.
Best Use Case: These builds are great for reviving the tablet as a dedicated e-reader, music player, or simple smart home dashboard.
This report evaluates the current status and feasibility of running LineageOS on the Samsung Galaxy Tab 3 7.0 (SM-T210R) . Current Development Status As of April 2026, there is no official support for the
from the LineageOS Project. The device is not listed in the official LineageOS Device Wiki, which typically provides verified builds and installation guides.
While official support is absent, the developer community (primarily on platforms like XDA Developers) has produced various unofficial builds over the years. However, due to the age of the
and its Marvell PXA986 chipset—which lacks open-source documentation—these builds often face significant hurdles. Technical Challenges
Installing modern versions of LineageOS on this hardware presents several obstacles: A dedicated group of maintainers on XDA Developers
Chipset Limitations: The Marvell processor makes porting modern Android kernels difficult compared to more common Qualcomm or Exynos-based Samsung tablets. Legacy Hardware: With only 1GB of RAM and a dual-core processor, the
struggles to run Android versions newer than 4.4 (KitKat) or 5.0 (Lollipop) efficiently.
Driver Issues: Common bugs in unofficial builds for this specific model include broken Wi-Fi, hardware acceleration issues, and camera instability. Installation Prerequisites
If you locate an unofficial build, the following tools and steps are generally required:
Unlocked Bootloader: Essential for flashing any custom software.
Custom Recovery: Tools like TWRP (Team Win Recovery Project) are needed to flash ROM zip files.
Flashing Tools: Samsung-specific software like Odin or the cross-platform tool Heimdall is required to install the custom recovery from a PC.
Sideloading: Once a recovery is active, the adb sideload command is typically used to move the OS onto the device. Alternatives and Resources For users looking to repurpose this device, searching for "
custom ROM" on community forums may yield older, more stable versions of CyanogenMod (the predecessor to LineageOS). You can also find technical discussions regarding software like Smt210r Lineageos Work Work, which may offer niche insights into specific development efforts.

is an older device that officially supports only up to Android 4.4.2 KitKat. While there is significant community interest in running LineageOS on this hardware, official support has been discontinued, and development is primarily unofficial.

The Samsung Galaxy Tab 3 7.0 (SM-T210R) remains a challenging device for modern software updates due to its unique Marvell PXA986 chipset. While LineageOS is the gold standard for breathing new life into old tech, users seeking to get it working on the T210R must navigate a landscape of unofficial builds and specific hardware limitations. Current State of LineageOS for SM-T210R
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:
LineageOS 14.1 (Android 7.1): Unofficial versions exist for the T210 series, offering a significant jump from the stock Android 4.4.2.
LineageOS 16.0 (Android 9.0): Experimental builds have been shared, though they often suffer from stability issues and "low FPS" in video playback.
Performance Reality: Even when LineageOS "works," the device's 1GB of RAM and aging Vivante GC1000 GPU mean that modern versions of Android (9.0 and above) often struggle with lag, particularly on sites like YouTube. Getting It Working: Key Requirements
To attempt a LineageOS installation on your SM-T210R, you must first secure the correct tools and recovery environment: Galaxy Tab 3 7.0 Android Development | XDA Forums
