[Impossible to turn on my Nexus 7

[watchurback]

Hi,
I have the Nexus 7 of 2012 and since 2 days I can't no longer use it !
Before yesterdaay , I could use the tablet but it was blocked/stock at a time. So I had to reboot the tablet and all functioned normally. However, yesterday, I found my tablet turned off. When I restarted it, the tablet was blocked after ten seconds ! Today , the tablet is unable to restart the tablet stuck in the bootup on the google screen or X screen !

I wanted to do a reset of my tablet in recovery mode but the tablet takes hours to do the reset . I watched youtube videos but the reset take about ten seconds . So I tried to reset with the Nexus Root Toolkit but when I launchedthe software , the program anonce that I need to enable "usb debugging" but I can not activate it because my tablet is turned of!

What do I do now ?? Help me

In the Nexus Root Toolkit there is an option on the right side to "Flash Stock + Unroot" with boxes below to check. Check the "Soft-Bricked/Bootloop" even if your not rooted it doesn't matter.
