Guess what guys, I got another Nexus 7 here that I think may have a similar problem. I used the Nexus 7 Rootkit 1.5 to try and unlock the bootloader, root, and install CWM on my Nexus 7 (HSPA+). I got the green light from the toolkit saying the process was completed and tablet booted into CWM Recovery. After rebooting the device, the root didn't seem to take and I noticed the file /system/recovery-from-boot.p was missing, but didn't think much of it as I had CWM, so when I went to reboot my tablet into recovery again the Nexus powered down, never to boot up again. The device is unresponsive. Any combo of power and volume buttons does nothing. I tried turning the device on while attached to my PC though USB and I heard the Windows sound when you plug in a device, but the tablet didn't display anything. adb devices shows me nothing. The battery was about 70% full when it occurred so I don't think it's dead, but it is on the wall charger now.
From reading this thread, it seems no one has any good leads on what I might try to do besides try and get it replaced or pay to have it fixed.
Any other suggestions?
*EDIT* Nevermind. It booted back up. Strange, I don't know how or why, the battery is still at 77%. I'm just glad it's alive. *EDIT*
