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.

Google Photos doesn't show people album outside US

Google Photos

One of the coolest new Google Photos features is "Group similar faces", which automatically detects faces in photos and groups them in "people" albums. Unfortunately, this option at the moment is only available in the US. The good news is that there is quite simple workaround that lets you to enable "Group similar faces" wherever you are.

The trick is to fool Google Photos that you are connecting from United States. The best thing is that this only needs to be done once (to enable "Group similar faces" option). After this is done, the feature will work regardless of where you are connecting from.
