I changed my password and dont remember. I tried the "forgot password" but is still deosnt work. I turned off my wifi and data before i locked my phone. Is this thr reason the "forgot password" doesnt work?
I have a Nexus 4
Hard reset brings it back to fresh out-of-the-box. If you've been using default gmail settings and a browser on a laptop, tablet or other device, then your contacts will probably be synced there and readily available, but not your downloaded apps or photos.
Warning: don't monkey around with it unnecessarily. Too many failed attempts at "breaking in" and the phone may end up in really serious trouble.
