Hi, I upgraded my samsung galaxy s to froyo 2.2 from 2.1 by going to How to Upgrade Galaxy S to Android 2.2 The upgrade was successful but now my samsung galaxy s is having a lot of problems. Like swype doesnt work, the voicespeak doesnt work. also the internet gets crashed a lot of times after installing flash 10.1 I am thinking if i upgraded via kies it wouldnt happen. But i am not sure so i would like to try. I factory reset my phone but it is still 2.2 How can i downgrade it to 2.1?
