Try harder.<p>Pretend there&#x27;s a phone on my desk now that was bought by someone else via ebay and reflashed to cyanogenmod. There actually was, its owner forgot it while visiting, but you can pretend that you&#x27;re a powerful snooping government and that&#x27;s my secret phone that you want to hack. Not registered in my name, not purchased by me, maybe there&#x27;s not even a SIM card in the phone. How do you go about &quot;just hacking into&quot; that phone or using the &quot;available backdoors&quot;?
