Hi,

I try to boot my Nexus 7 (2013/wifi). I have access to :

• a white google logo


• a fastboot access


• and a recovery mode (with a sideload option)

I was reading my email when the tablet suddenly reboot and stuck on the Google logo. Now, I don't know what can I do.
doesn't work (FAILED <unknow error>).
I can flash a new bootloader (FLO-04.04) but can't unlock it.
