For the sake of clarity, only the talk of the programs themselves will be in the following, depending on the operating system command but for example by ./fastboot-linux or replace ./adb-mac; Windows file extension must be considered: fastboot.exe.

Is below the last command a device number to see the procedure can go on. Since the Nexus 7 comes directly from Google, the boot loader can be unlocked without fuss with the command fastboot oem unlock. now a warning label that briefly explains the consequences of unlocking appear on the tablet. Using the volume rocker to navigate to the corresponding Manüpunkt and accepted with a brief press on the power button. Now the red text should (bottom left "Lock State &# 8211; Unlocked ") show. If one examined by the volume keys the menu item "Reboot" and starts with the power button, the tablet.

In particular, Linux prepares the fact that newer Nexus devices no longer distinguish between system and mass storage, still problems. If the Nexus 7 is not as MTP device ( "Media Transfer Protocol") is detected, the file can also be transferred via the command adb push / sdcard /.

the archive is located on the SD card, the tablet has again turned and started with the now familiar key combination in the fastboot mode. In the console to type now in command fastboot flash recovery recovery-clockwork-touch- one in order to install the custom Recovery ClockworkMod.
