Fixing LineageOS 14.1 20180419 Unofficial GTE LTE 3G Issues

Now that we've covered the common issues and potential causes, it's time to dive into the fixes!

Step 2: The "No SIM Card / No IMEI" Fix (RIL Layer)

This is the core issue. After the 20180419 flash, your Baseband version shows "Unknown" and you have no cellular data.

The Procedure:

1. Download the gtel3g_ril_patch.zip (A community-made package containing libbrcm_ril.so, libril.so, and libreference-ril.so from stock S7390).
2. Boot into TWRP.
3. Mount the System partition (check the box).
4. Flash gtel3g_ril_patch.zip.
5. Critical step: Go to Advanced -> File Manager. Navigate to /system/vendor/lib/. Delete the file hw/keystore.bcm2166x.so (This specific keystore file conflicts with RIL on the 20180419 build).
6. Wipe Cache/Dalvik.
7. Reboot. After booting, wait 2 minutes. Your IMEI should reappear in Settings -> About Phone -> Status.

Step 3: The Wi-Fi MAC Address "02:00:00:00:00:00" Fix

A broken Wi-Fi MAC prevents connection to secured networks.

The Fix (Requires root after boot):

1. After fixing the RIL and booting successfully, enable Developer Options and Root Access (for ADB only).
2. Open a terminal on your PC:

   adb shell
   su
   mount -o rw,remount /system
   echo "macaddr=00:11:22:33:44:55" > /system/etc/firmware/nvram.txt
   chmod 644 /system/etc/firmware/nvram.txt
   

3. Reboot. Your Wi-Fi will now work.

2. Camera Not Working

The camera may crash or show a “Can’t connect to camera” error.

Fix:

• Install a third-party camera app like Open Camera (works reliably).
• If the stock camera is needed, replace libcamera.so with the version from the stock Samsung firmware (requires root).
• Pro tip: Disable “Zero Shutter Lag” in camera settings to improve stability.

Fix 4: Clean Flash and Reinstall

If you're experiencing issues after a dirty flash or incomplete installation, try performing a clean flash and reinstalling the operating system:

• Backup your data: Before performing a clean flash, ensure that you backup your important data to prevent loss.
• Perform a clean flash: Follow the instructions for a clean flash on the LineageOS wiki or forums.
