Mettiamo il device in fastboot mode
Da spento premi i tre tasti insieme sino alla apparizione a schermo di un robottino steso con pancia aperta
Questa è la modalità FASTBOOT
Collegalo al PC

Ora che mi ricordo forse avevi chiesto anche altrove ..
o forse era un altro ...
... ma io sto APX non so proprio cosa sia ...

Ho googlato un po ...

PROVA 1.
press VOL-DOWN (and hold) followed by the POWER BUTTON (hold both for 20 or 30 seconds). This should boot your device into the bootloader itself and from which you should be able to fastboot flash a Google factory stock image

COMBINAZIONI VARIE di BOTTONI
Starting from Device OFF Condition:

Power (2-3 seconds) -> Normal OS Boot**
Vol-Up + Power (1-3 seconds) -> APX Mode
Vol-Down + Power (6-8 seconds) -> Bootloader/fastboot Mode (keep both buttons pressed until you see the droid lying on his back).


Starting from APX Mode:

Power (10-15 seconds) -> Normal OS Boot**


Starting from booted or boot-looping OS:

Power (10-15 seconds) -> Normal OS Boot**


** Bootloader Interrupt: In any of the cases where you hold the power button down to try to break out of the current operating mode, if you press the Vol-Down button right after you first see the black and white screen with the Google logo, the tablet will proceed immediately to bootloader/fastboot mode, rather than booting the normal OS. You need to be ready though - you only get about 1 or 2 seconds to do this! (Thanks to RMXO for pointing this out) Note that this means you can get to the bootloader directly from any other mode!

This also explains why, when attempting a cold start using Vol-Down + Power, if you accidentally let go of the vol-down button when the screen first lights up, the Nexus 7 will boot to the normal OS. In this case, pressing Vol-Down initially is actually superfluous - what makes the device go into bootloader/fastboot mode is the Vol-Down press immediately following the google splash screen - there actually is no unique "Go to fastboot from a cold start" method.


Starting from Bootloader/Fastboot Mode:

Follow the instructions on-screen.


Starting from Stock Recovery Splash Screen:

Power + Vol-Up simultaneous press -> gets you to the hidden stock recovery Menu.

For me, pressing Vol-Up first and then Power does not seem to work here - they seem to need to be pressed simultaneously.


Starting from Custom Recovery:

Follow the instructions on-screen.


Screen Shot in Booted OS

Press Power + Vol-Down Simultaneously & hold for about 1 second. The simultaneous part seems to be important, as well as holding them down together for the one second or so. A fine example of a simply horrid UI implementation. (Google, can your Grandma perform this trick?)


Safe Mode Boot

From a cold start boot (press & release Power button), wait 2 seconds after the B&W Google (bootloader) splash screen appears, then press and hold Vol-Down button until the normal OS boot is fully completed (lock screen or home screen appears)
