Guys, i've made an backup of my system and i formatted it with all data and cache. So i had a problem with the installation of cyanogenmod, because of this I tried to restore my backup, but my nexus doesn't start anymore. I tried to instal another android version from adb but my pc doesn't recognize my tablet.

Someone could help me please?

Fixing adb "Device not found" with Nexus 7/Android devices in Recovery Mode

[Rukbat]

If adb doesn't even recognize the tablet, you may have deleted all 3 systems - normal, recovery and download. In that case you have hardware with no software, and your only way out may be a JTAG service (look on eBay) or Google itself. Considering that it's almost a 3 year old device, it may not pay to fix it.
