Nexus 7 users whose devices have become unresponsive but boot into Fastboot mode may easily fix this or unbrick them using the stock Android Factory Image by Google.

Those who wish to unbrick their Nexus 7 and restore stock Android firmware may follow our step-by-step guide. Even if the device is not bricked users may follow the method to restore the device to stock Android firmware.

The unbrick method below supports both the Nexus 7 2012 and 2013 models with Wi-Fi and LTE connectivity. Therefore, verify the model number and install Factory Image according to the model number of the device.

Note that Android Factory Image when applied on devices such as Nexus 4, Nexus 5, Nexus 7, Nexus 10 and older Nexus devices, restores to 100% stock firmware, while removing all data. Besides, users may use a newer Factory Image and flash it over the older version, which is an alternative to an update.
