Sony Xperia Z3 forgotten lock screen passcode

marina33 — Wed, 16 Sep 2015 18:31:11 GMT

So my friend changed my lockscreen passcode and neither of us remember it.

Is there a way to change it or something because I need my phone and it's pretty much useless now.

I tried PC Companion which doesn't work because I my phone needs to be unlocked. And the thing with ''Forgotten passcode?'' doesn't appear at all.

Please help!

What if MyXperia isn't enabled because it seems to me that it isn't?

Do you have an antivirus app? bc that might be the problem, boot on safe mode and try again

also if you don't care about the data stored on your phone

run pcc > turn off your phone > repair the phone > the phone must remain off

Booting into the safe mode didn't work. Is there anything else to try?
