Upgrading a 2012 Google Nexus 7 to Android 5.0
19th November 2014Today, I was lured into upgrading my 2012 Google (ASUS) Nexus 7 to the final version of Android 5.0 (also known as Lollipop) by an icon in the device's top panel. Initially, it felt as it was working OK but a certain sluggish could not be overlooked and there have been complaints about this with some questioning the sense of what Google has done. However, there would have been remarks about grandfathering the device if they had not left us to have the latest release of Android, so there was no victory either way. We humans are fickle creatures, and there is an example of exactly that in a well observed double-ended short story by the Irish writer Maura Laverty.
While my impressions of how the upgrade had lumbered the tablet had me wondering about replacing the thing with either an Apple iPad Mini 2 or a Google (HTC) Nexus 9, a much less expensive option came to mind: doing a full factory reset of the device using its recovery mode. Though that may sound drastic, much of what I had on there was in the cloud anyway, so there was nothing to lose. So these are the instructions from Google themselves and I will leave you to use them at your own risk:
- If your tablet is on, turn it off.
- Press and hold the Volume Down button, then press and hold the Power button at the same time until the tablet turns on. You'll see the word "Start" with an arrow around it.
- Press the Volume Down button twice to highlight "Recovery mode".
- Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation mark and the words "No command."
- While holding down the Power button, press the Volume Up button.
- Use the volume buttons to scroll to "wipe data/factory reset," then press the Power button to select it.
- Scroll down to "Yes - erase all user data," then press the Power button to select it.
Note: If your tablet becomes unresponsive at any point during these steps, you can restart it by holding down the Power button for several seconds.
Once that was completed and the tablet restarted, the set-up routine began and took around an hour to reinstate the various apps that had been lost by the rest. Much of that was down to the time taken for re-installation rather than that taken by the actual downloads themselves over a wired broadband connection. The wait was worth it because the Nexus 7 feels more responsive again. While there are times when little lags are noticeable, they are nothing next to the slowdown that I had witnessed before the rest. It might have been a better option than attempting to return to Android 4.4.4 using a factory image, which was another option that I was considering. So long as there is no deterioration in speed, the effort expended to do a reset will have been worthwhile.
