Yeah that was kinda my problem. I tried to reset my phone and it got bricked, 2 weeks from the repairs and they didn't reset it right and I had to reset it again to fix it. Its all good now
Just a note for anyone who experiences this, here is why this might be happening.
If you (like me) have a windows phone without SIM, your phone *WILL NOT UPDATE TIME/DATE THROUGH WIFI*. Just set the date/time and the annoying/mysterious/user un-friendly 80070020 will not bug you any more...
That explains so much, my time wouldn't update properly and I tried to add a nokia account in the settings and I kept getting an error about the time and date
