I was finally able to download the firmware on my PC and upgraded my phoneMy firmware download failed halfway through...I tried a few times. I will try again when I get home...if I can download the firmware I will update if it worked for me or not.
I got my Nokia Lumia 820 back on June 17 and was confused as to why I couldn't update my phone through the Settings. Found out others with AT&T in the US were having the same problem. I did another check today, and I finally managed to download an update through the options. It's currently updating right now, so I'm hoping there are no errors.
Edit: On update 1314 now, seems nothing went wrong so far.
I updated my 820 via NSU for retail (India)
(Vodafone user btw)
These are the changes I got :
1.Storage Check in settings
2.Data Sense
3.I am getting HSPA+ signal on 3G mode
4.Scrubbing response on HD videos has improved a lot
5.Music Player is little fast
Problems :
None so far , Apps are getting updates , able to install apps through SD-card , backing up is fine , camera works fine.Everything is very nice.
Most importantly no bugs.
EDIT : For those who want to update , here's the installation software :
Nokia Software Updater for Retail 2.0.6.rar
Data will be wiped and u can easily restore it when phone restarts after update
