Problems updating Nexus 7 (grouper) to Android 4.4.2

Latest update failed (4.3 to 4.4.2 I think) – just a forever spinning Nexus logo. Overwrote the tablet with a stock Nexus 7 (nakasi) image and all is well, besides needing to reconfigure everything and put my files back on it (thankfully Moon Reader Pro syncs positions with Dropbox/Google Drive).

You need the Android SDK installed (remember to add it to your path) and to have rooted the device – both covered in an earlier post. On the device hold down the power, volume up and down keys until the rescue screen appears.

Connect with USB and open a command prompt/terminal then type:

adb reboot bootloader

Download a stock image from Google – the Nexus 7 (nakasi) is this one. Decompress it and go to that folder in the command prompt/terminal, run either flash-all.bat (Windows) or flash-all.sh (Linux) and follow the prompts.

Nexus 7 screen not coming on

My Google Nexus 7 had a weird fault earlier, its screen wouldn’t come on – just what you need before a nine hour flight. I tried a reset – it appeared to be caught in a loop with some static displayed on screen. I thought I might remove the back cover, disconnect the battery and take it from there.

Glad I did – the battery connector wasn’t engaged properly. A piece of insulating material had got in the way, preventing the connector locking in place. It must have worked loose.

Since then I’ve seen a few threads on Reddit with people mentioning that disconnecting and reconnecting the battery had fixed the same issue. I wonder if this is something more common than I thought?
