Hello, new here. Coming from a iPhone4, downgraded to my old standby Samsung Eternity and now waiting for my new unlocked Samsung Galaxy Ace S5830 to arrive. Have done a lot of research. Loaded Kies, Odin, etc. I have a good understanding of what is necessary to upgrade firmware and what problems to look out for and their fixes....... My question here is what is the latest STABLE Official Gingerbread 2.3.6 Build for USA to upgrade to? Most all Build's I find are from/for other regions/countries. I have found and downloaded two that I think are correct as the latest for the S5830 Galaxy Ace: Gingerbread S5830XWKTM 2.3.6 (4/9/2012) Gingerbread S5830XWKTS 2.3.6 (10/24/2012) I see there are many others: S5830XXLH4 (10/2012) is one.........it's just so confusing to me. Now it is my understanding that I should be able to upgrade to the latest Official thru Kies and I assume that will be the XWKTS (10/24/2012). But even if that is possible, I may prefer to use Odin. So I am asking if I do decide to use Odin, should I load the XWKTM, XWKTS, XXLH4 or something else? And why can I not find release notes for all these Builds (in sequential order and one place)? I would like to know what has been improved since the original factory firmware (Froyo 2.2) and which one is the most stable/functional? Thanks for your suggestions/comments.
