Finally I was able to update my Samsung Omnia W to latest Windows Phone release WP7.8. Thanks to
these 2 links (Source 1 and Source 2), I was able to update my Samsung Omnia W
to WP7.8.
As mentioned in links, I followed the process of
disconnecting and reconnecting network cable several times. After several
attempts I was able to upgrade to WP7.8.
I will mention steps again-
1. Turn
phone to Airplane mode to disconnect all network (Cellular/WiFi).
2. Connect
Phone to PC using USB cable and start Zune.
3. Go
to Settings > Phone > Update.
4. If
it displays that your phone is having latest update, go to some other option in
setting.
5. Now
be prepared to disconnect your internet in 1-2 (or 3) seconds.
6. Click
again on “Update” and in 1 or 2 or 3 seconds disconnect internet of your PC by
pulling off network cable, or turning off WiFi.
7. If
successful (may take several attempts), Phone will display update available. I
got 3 Updates as mentioned below before I got latest update.
7.10.8779.8.
7.10.8783.12.
7.10.8558.136
(This is latest Update of WP7.8).
I had to follow steps of disconnecting cable for all above
mentioned updates. It took 2-3 hours for me till I got all updates, so patience
is needed to try for several attempts.
Although as mentioned in 1 link above, I dint get any update from Samsung. May be Samsung would send their updates later.
I am able to resize my tiles, and new accent colours available, and also able to set Bing as Lock Wallpaper.
Now I have below versions in my phone-
OS Version:
7.10.8858.136

number: 2424.12.04.3
