I've had my Nexus 7 for a while, and I actually recently got a Nexus 10 and handed off the 7 to my fiance, who was using it to browse tumblr and read fanfiction, and that's about it as far as I can tell. I do have it rooted and unlocked and running Paranoid Android Beta 4.6 (and has been for a very long time), however since I haven't messed with it in so long I couldn't tell you anything else about it (kernel, etc.)
Since I know she wouldn't have tried to do anything like update or anything like that, my guess is that the problem is stemming from the fact that she just lets it die a lot, then charges it. She charged it all night and it would not turn on so she had me look at it. I tried everything I could think of, holding power for various amounts of time, both alone and in combination with either of the volume buttons to try to access fastboot or just anything. I should mention I even followed Google's troubleshooting steps, which involved strange charging times, having it plugged into the PC for a spell, then unplugging and replugging and trying to power on. But the battery icon does not even show up. The screen just stays black.
I plugged it into my computer to see if anything would happen, and it showed up in Device Manager as QHSUSB_DLOAD, so I googled this problem and it seems to be some sort of hardbrick where the bootloader is corrupted, and some people have found solutions for other devices, mainly HTC devices, but there doesn't seem to be anything that particularly pertains to this device. If I hold down the power button while plugged into the PC it will intermittently "disconnect" and "reconnect" (Windows plays the sounds) and disappear and reappear in Device Manager.
I'd like to try to fix it if I can, but I'm not gonna send it in for repairs/replacement or anything like that. I'd rather just buy a brand new device at that point, but if anyone somehow has a solution, I'd gladly welcome it.
Thanks so much!
