For users seeking to upgrade their aging Samsung Galaxy Tab E 9.6 (SM-T561/T560), the unofficial LineageOS 14.1 (build 20180419-unofficial-gtel3g) remains a popular, though legacy, choice for moving beyond the stock Android 4.4.4 KitKat. ROM Overview: LineageOS 14.1 for gtel3g

Conclusion

3. Flashing Instructions

Step 1 – Boot into TWRP Recovery

• Power off device.
• Press and hold Volume Up + Home + Power until Samsung logo appears, then release.

Unlocked Bootloader: Most SM-T561 models come with an easy-to-unlock bootloader via Odin.

The world of custom ROMs is vast and vibrant, offering Android enthusiasts a way to push their devices beyond their stock capabilities. LineageOS, with its emphasis on stability, security, and customization, remains at the forefront of this movement, empowering users to get the most out of their smartphones.

• Developer-applied fixes beyond the upstream Lineage/Android source: security patches, device-specific bug fixes, camera/audio/thermal tweaks, or kernel modifications.
• Could also indicate backported newer security fixes to an older build or vendor-binary workarounds to enable features (Wi‑Fi, modem, sensors).

Do not attempt to flash this on the Wi-Fi-only model (SM-T560/gtelwifi) or the Qualcomm/Verizon variants (SM-T560NU), as this will likely result in a hard brick. 2. Why "Patched"?
