Important Information

Samsung devices come with a unique boot mode called “Download mode”, which is very similar to “Fastboot mode” on some devices with unlocked bootloaders. Odin is a Samsung-made tool for interfacing with Download mode on Samsung devices. The preferred method of installing a custom recovery is through Download Mode – rooting the stock firmware is neither necessary nor required.

1. Enable Developer Options by pressing the “Build Number” option 10 times, in the “Settings” app within the “About” menu
   • From within the Developer options menu, enable OEM unlock.
2. Download a custom recovery - you can download TWRP. Simply download the latest recovery file, named something like twrp-x.x.x-x-gts4lv.tar.

   Tip: Ensure you download the .tar or the .tar.md5 file and not the .img version.
3. Power off the device, and boot it into download mode:
   • With the device powered off, plug in the device while holding Volume up + Volume Down + Power.
   • Now, click the button that the onscren instructions coorelate to “Continue”, and insert the USB cable into the device.
4. Download and install the necessary drivers.
   • Download the newest Samsung drivers from here. You will need to create a Samsung account and login to download them.

12. Unplug the USB cable from your device.
13. Manually reboot into recovery, this may require pulling the device’s battery out and putting it back in, or if you have a non-removable battery, press the Volume Down + Power buttons for 8~10 seconds until the screen turns black & release the buttons immediately when it does, then boot to recovery:

Installing LineageOS from recovery

1. Download the LineageOS installation package that you would like to install or build the package yourself.

2. If you are not in recovery, reboot into recovery:
   • With the device powered off, hold Volume Up + Power.
3. Now tap Wipe.
4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
5. Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions and then Swipe to Wipe.
6. Sideload the LineageOS .zip package:
   • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.

     check

     Tip: If the process succeeds the output will stop at 47% and report adb: failed to read command: Success.

7. (Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.

   info_outline

   Note: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!
8. Once you have installed everything successfully, run ‘adb reboot’.
