Two weeks ago, on Halloween, Google promised that factory firmware and binaries Android 4.4 KitKat for Nexus 4, Nexus 7 and Nexus 10 will be published immediately after these devices receive over-the-air updates.

And despite the fact that not all tablet models have received automatic update up to Android 4.4 KitKat, factory firmware with this version of the system (build Android 4.4 KRT16O) has already been published on the Google server. You can download them and install them on your tablet or smartphone yourself. How to do this, read on.

This news will also please those who would like to return to stock Android after installing custom firmware, such as Cyanogenmod, Paranoid Android, etc.

Note: Please be aware that if your bootloader Nexus 7 blocked, during the firmware update there will be a complete loss of all your personal data on the tablet. You can unlock the bootloader using the fastboot program, which will also clear the data. On Nexus 4 and Nexus 10 You can unlock the bootloader without losing data using BootUnlocker.

Note 2: If the bootloader is unlocked, you can install new firmware without data loss, however, in some cases, after this the tablet or phone will not boot, so be prepared for the fact that you will have to flash your device with data loss and take care of backing it up.

Requirements:

First of all, to flash the firmware, you will need a computer with Android SDK, or rather - adb programs and fastboot coming with it. How to install the Android SDK, read this material.

Also, you will need a MicroUSB cable to connect the tablet to your computer. It is better to use the cable that came with the tablet.

How to unlock bootloader on Nexus 7 using fastboot:

1. Connect your tablet to your computer and boot it into bootloader mode ( adb command reboot bootloader or by turning it off and on by simultaneously pressing the power and volume down buttons).

2. Enter in the window command line(terminal) computer command:

fastboot oem unlock

Confirm unlocking (volume up, then power buttons).

Instructions for flashing Nexus tablets and phones

1. Download the factory image with firmware for your tablet model to your computer (for example, Nexus 7 Wi-Fi 2013 is called razor, and Nexus 7 Wi-Fi 2012 is called nakasi) from this page of the Google website. This image contains the system itself, bootloader, factory recovery, kernel (boot.img) and radio module (not included for Wi-Fi models). Therefore, if you installed, for example, an alternative recovery, after the firmware it will be replaced with the stock one.

2. Unpack the downloaded tgz (tar/gz) archive into separate folder. I use Total Commander for these purposes, but you can use a separate archiver, for example, 7-Zip.

3. This step is needed if you want to avoid data loss during flashing:

With the help of anyone text editor open (Caution! Open and do not run!) the file flash-all.bat (if you have Windows) or flash-all.sh (Mac, Linux) and remove the two -w characters in the line with the fastboot update command. For example, if the line says: fastboot -w update image-razor-jss15j.zip, after editing it should look like fastboot update image-razor-jss15j.zip. Save the file. (It is the –w option that causes the data to be cleared.)

4. Reboot the tablet into bootloader mode, make sure it is connected to the computer and run the flash-all.bat script (or flash-all.sh on Mac, Linux).

Congratulations, you did it!

For security reasons (so that no one can remove your device's screen unlock key or gain access to your data if your tablet or smartphone is lost or stolen), it is recommended to keep the bootloader locked. To do this, there is the fastboot oem lock command (for Nexus 7) or the BootUnlocker application mentioned above for Nexus 10 and Nexus 4.

Root on a tablet or smartphoneNexus after firmwareAndroid 4.4KitKat

Rooting your Nexus is very easy. To do this, you will need an unlocked bootloader and a modified recovery. I would recommend you to use TWRP. You can download the latest version of TWRP recovery from here. To do this, click on the "Get TWRP for your device" button and type the name of the tablet in the window that opens (for example, Nexus 10).

1. Connect the tablet to the computer and boot it into bootloader mode (read how to do this above)

2. Enter the command in the command line window (terminal):

fastboot flash recoveryFileNameRecovery.img

3. Now you can reboot your tablet into a new recovery using the command:

adb reboot recovery

In addition, tablets and Nexus smartphones You can reboot by turning it off completely and turning it on by pressing and holding the volume up and power buttons at the same time.

4. Download zip file With new version SuperSU.

5. Flash the downloaded zip file (without unpacking!) using TWRP

6. Reboot your device, launch Play Store and update SuperSU.
