Well, I am running Cognition 2.2beta1 and 2.2beta2 just reeleased today and I wanted to flash up to it. I read on XDA you have to flash back to 2.1 then up to beta2, so there is a write up about it here
[STOCK ROM] Odin3 One-Click Downloader and Drivers CAPTIVATE ONLY - xda-developers
It says to use this Odin program to flash back to stock 2.1. I am attempting to do that now, Odin is running (i think) and has been doing a "file analysis" for the last half hour, so i am wondering what is going on and how long that is supposed to take. Flashing to cog 2.2 was qucik and easy.. not sure why its taking so long..
Update: Odin finished (i guess) and said <OSM> All threads completed. (Suceed 0/failed 1). so I am guess ing it failed..
