Nexus 7 powers on, but is stuck on the start screen.

I tried to root my Nexus 7 using a Nexus Root Toolkit program while the device was connected to my PC. Initially I was successful, but then had issues running some apps on the device. I decided to restore my Nexus to factory settings using the root program to do so. I'm not quite sure what I did, but the device has been stuck on the start up screen ever since, with the white "Google" letters showing, and a lock in the unlocked position showing at the bottom of the screen. Nothing is affected if I touch the screen or toggle the volume buttons. If I had down the power button it simply powers off, and returns to the same screen when turned on. The Nexus Root program still recognizes the device, but does nothing if a command is run. I'm afraid that I might have "bricked" the tablet, as I had read it described.

I fixed a Nexus 7 wifi (2013) about 3 years ago. The main thing that helped was that I did the procedure over and over again - 8 times to be precise. I had given up and had left it on at the white “GOOGLE” and while I was watching TV it booted up!!!

Why does this happen? It is because each time it slightly repairs itself but not enough to completely boot up. Eventually it reaches that crucial point and boots up. Have gone through this with computerts, etc. many times.

Most people give up too early…thinking about it that’s what peoiple often do in life in general.

This is a general guide. I can’t remember exact details - it was over 3 years ago.

Factory Images for Nexus Devices

This page contains binary image files that allow you to restore your Nexus device's original factory firmware. You will find these files useful if you have used the Android Open-Source Project, flashed custom builds on your device, and wish to return that device to its factory state.

These files are for use only on your personal Nexus devices and may not be disassembled, decompiled, reverse engineered, modified or redistributed by you or used in any way except as specifically set forth in the license terms that came with your device.

Flashing Instructions

To flash a device using one of the system images below (or one of your own), you need the latest fastboot tool. You can get it from one of the sources below.

  • From a compiled version of the the Android Open Source Project.
  • From the platform-tools/ directory in the Android SDK. Be sure that you have the latest version of the Android SDK Platform-tools from the SDK Manager.

Once you have the fastboot tool, add it to your PATH environment variable (the flash-all script below must be able to find it). Also be certain that you've set up USB access for your device, as described in the Using Hardware Devices guide.

Caution: Flashing a new system image deletes all user data. Be certain to first backup any personal data such as photos.

To flash a system image:

1.       Download the appropriate system image for your device below, then unzip it to a safe directory.

2.       Connect your device to your computer over USB.

3.       Start the device in fastboot mode with one of the following methods:

o        Using the adb tool: With the device powered on, execute:

adb reboot bootloader

o        Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device. For example, to put a Nexus 5 ("hammerhead") into fastboot mode, press and hold Volume Up + Volume Down + Power as the device begins booting up.

4.       If necessary, unlock the device's bootloader by running:

fastboot oem unlock

The target device will show you a confirmation screen. (This erases all data on the target device.)

5.       Open a terminal and navigate to the unzipped system image directory.

6.       Execute the flash-all script. This script installs the necessary bootloader, baseband firmware(s), and operating system.

Once the script finishes, your device reboots. You should now lock the bootloader for security:

1.       Start the device in fastboot mode again, as described above.

2.       Execute:

fastboot oem lock

Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.
