Installing LineageOS on Samsung Galaxy S7

I used below instructions to flash LineageOS on a stock Samsung Galaxy S7 (herolte, arm64, exynos 8890). no rooting was required. If you intend to follow these instructions, do this at your own risk - this will surely delete all data on your phone and void manufacturer's warranty. Also, there is always a risk of bricking your device. Proceed at your own risk!

Installing custom OS on original Nexus 7 (2012)

Before starting, make sure you have working adb (Android Development Bridge) tool on your PC. adb.exe is part of Android SDK, so if you have Android Studio, you should already have adb. If not, you can download Android Studio (or SDK only) from developer.android.com.

Warning: following instructions below will wipe all data on your tablet.

Step 1 - Unlock bootloader 

  • Enable USB Debugging on Nexus 7. Settings > Developer Options > USB Debbuging
    Developers Options by default are disabled on all Android tablets. To enable them, got to Settings > About tablet and tap multiple times on Build Number
  • Connect Nexus 7 to your PC with USB cable. When you get a prompt "Allow USB debugging" choose OK.
  • Open command prompt and navigate to the location of adb.exe.
    Exact path where the file is located depends on where you installed Android SDK. i.e. D:\sdk\platform-tools
  • Run command adb reboot bootloader
    Nexus 7 should reboot into FastBoot mode.
  • Run command fastboot oem unlock. Accept a warring on the device.
  • Nexus 7 should now have bootloader unlocked.
