I just got this nice Samsung Galaxy Tab S2 Value Edition (9.70″, 32GB, White) with WiFi, and had a very easy time to load the latest LineageOs build on it.
The steps involved are basically:
- Enable OEM unlock in the settings
- Flash a custom recovery image: TWRP from TeamWin
- Sideload the LineageOS image
- Optionally sideload the Google Apps via OpenGAapps
Since the required files tend to go away, I host them here for future reference:
