You’ll see a warning message on your device’s screen; confirm that you want to unlock the bootloader using the volume and power buttons.
What Is A Custom Recovery, And Why Do I Need It?
A custom recovery, like TWRP or CWM, is a replacement for the stock recovery environment on your Nexus 7 (2012). It provides advanced features that are not available in the stock recovery, such as the ability to flash custom ROMs, create and restore backups of your entire device, and install root packages like SuperSU or Magisk. Think of it as a more powerful and versatile recovery system.
You need a custom recovery to root your Nexus 7 (2012) because it allows you to flash the necessary files (like SuperSU or Magisk) that grant root access. These files are typically not recognized by the stock recovery, which is designed primarily for factory resets and official updates. Custom recoveries also offer the ability to make full backups of your device before rooting, allowing you to easily restore your device to its previous state if something goes wrong during the rooting process.
How Do I Install A Custom ROM On My Rooted Nexus 7 (2012)?
Installing a custom ROM on your rooted Nexus 7 (2012) allows you to completely change the operating system and experience new features and optimizations. First, you need to find a custom ROM that is compatible with your specific Nexus 7 (2012) model and download the ROM file (usually a .zip file) to your computer. Also, download the Google Apps package (GApps) that corresponds to the Android version of the ROM, as custom ROMs often don’t include Google apps by default.
Next, connect your Nexus 7 (2012) to your computer and transfer the ROM and GApps files to your device’s internal storage. Then, boot your device into your custom recovery (TWRP or CWM). In the recovery, perform a “wipe” or “factory reset” to clear the old system data. Finally, select “Install” and choose the ROM file, then flash it. After flashing the ROM, flash the GApps package in the same way. Once both are installed, reboot your device. The first boot after flashing a custom ROM may take a while, so be patient.
