Maybe you guys should try this:
Nokia_Software_Updater_for_Retail_2.0.6.zip_
it is from a chinese website cloud but it actually works, I've tried it last night and it worked like charm
I know most people can't read chinese, so the "download" buttons is the one directly below the time "9:30", don't worry, everything in the file is in English, chills...
Remember to back everything up in your phone and try not to use the phone while it is updating because according to the instruction, your phone will brick if you do so.
Just wait patiently for 1++ GB to be downloaded and then update Extras+ Info "http://forums.windowscentral.com/nokia-lumia-822/210445-force-nokia-app-settings-updates-qr-code-links.html"
There you go, you now have the new "Storage Check" option!!
Enjoy!
