I have a android on operating system 2.3.6. It is AT&T however I had it unlocked for another provider so the auto updater doesn't work as I'm not using them as a provider. So I want to know how to manually update a phone and also how to tell what the max update your phone is compatible with is. Also risks involved. Thank you.
