Common Issues & Fixes for the gtel3g Lineage 14.1 Build Since this is an unofficial build from 2018, users often encounter specific bugs. Here are the solutions (fixes) for the most common problems associated with this specific release. 1. The "SD Card Unexpectedly Removed" Bug This is the most prevalent issue on the gtel3g lineage builds. The device often drops the mount point for external storage. The Fix: lineage14120180419unofficialgtel3g fix
Boot into TWRP Recovery . Go to Mount > Check Data . Go to Advanced > File Manager . Navigate to /data/system/users/0/ and delete the file named runtime.xml (if it exists). Reboot the system. Alternative: Format the SD card as Internal Storage (Adoptable Storage) rather than Portable Storage, though this encrypts the card and makes it unreadable by PCs.
2. Bootloop After Installation (April 19 Build Specific) If the device is stuck on the LineageOS boot animation after flashing the April 19 build. The Fix: This usually happens if the existing Vendor partition is outdated.
Download the latest Stock Firmware for the SM-T531 (use a tool like SamFirm or Frija). Extract the NON-HLOS.bin file from the stock firmware (this is the modem/vendor partition). Flash this file via Odin or TWRP to ensure the vendor partition matches the LineageOS expectations. Project Overview: LineageOS 14
3. SELinux Permissive Mode Many unofficial builds for the Tab E 9.6 required SELinux to be set to Permissive to function correctly. If apps are crashing (Google Play Services, Camera), the SELinux policies are blocking them. The Fix:
You need to edit the kernel command line or use a root app like SELinux Mode Changer . Set the mode to Permissive . Note: This reduces security. Only use this if apps are unresponsive.

Root: This build usually comes unrooted. If you need root, flash Magisk v20.4 (newer versions may break on Android 7.1) or SuperSU.
