From the current software I'm using now, which is the stock captivate ROM + rooted + EXT4 lag fix, it gets to the white screen and at 50%, it says update is failed. I removed root and EXT4 fix and still gets to 50% and fails.

So, I reinstalled the stock ROM from scratch, and now when I check for updates it says no update found.

Can someone upload a Stock ROM of the update?
