Google Nexus 7 (2012)

First impressions on the Google Nexus 7. Feels hefty and solidly-built. I'm liking the rubberized, pimpled back. Screen is sharp, bright, and colors vivid. Very smooth and responsive. The only part I didn't like is the thick bezel around the screen.

Ten minutes into powering up the Nexus 7, a notification came up saying 4.3 upgrade ready to be installed. Sure, the latest is always the best. The device booted up, and the multi-coloured X icon came up. Five minutes went by, and the X icon is still there. Long press on the power button to turn off the device.
The tablet simply reboots and gets stuck on the X screen. Time to hit the forums. Apparently, quite a few people have encountered this problem, and the general consensus is that a reflash is required.

First, a few prerequisites:
 - You'll need USB drivers, so that the PC/laptop can talk to the device.You can download the drivers directly from here.
 - You'll need to download the Android SDK to get the adb and fastboot platform tools. Some devs might provide a stripped-down package, but best to get the tools straight from source.
 - Then, you'll also need the stock 4.3 ROM image for the device here.

Full instructions for the restore is available here. Quick instructions below:
 - Reboot into the bootloader using Power + VolDown
 - "fastboot oem unlock" to unlock bootloader. Note that this will wipe your data.
 - Unpack the ROM image, which is in tgz format. Best to unzip it in the same folder as the platform tools
 - Again, reboot into the bootloader.
 - Run flash-all.bat
