With the ever increasing threat of malware infection of Android tablets, I would like to know how I could recover my Nexus from a software-damaged condition.
I've considered rooting & creating a custom backup, but it looks a bit scary for me at the moment. For now it would be sufficient to know how to reboot to factory settings. I have backups of all my data. I believe there is a process using the power & volume keys from a cold boot.
I have installed Avast anti-virus but this does not make the Nexus totally safe.
