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!

Get rid of Android "SD card encrypted" notification

After rebooting an Android phone that has encrypted SD card, you may get following notification:

SD card encryption
SD card encrypted

Can't encrypt LG G4 (android 6.0) - device reboots but doesn't start encrypting

Issue

Cannot enable full phone encryption on LG G4 (Android 6.0). After enabling encryption in Settings > General > Security > Encrypt Phone, the smartphone restarts, but encryption remains disabled.

Resolution

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.
