Ive just plugged my phone into kies and it said i had a firmware upgrade. Followed all the instructions correctly. It completed ok, and said "firmware has successfully installed" etc. Now though the phone wont go past the boot screen. It just continuosly cycles through the flashing "Galaxy S" animation on start up. What has happend and what can i do!? I was on 2.2 froyo which i had sucessfully upgraded to using Kies about 6 months ago when it came out.
