What's Odin?

[ProRezOnline]

ok - its been 3 hours now and Odin has a red cell on it which says FAIL! The data listed below that is as follows:

<OSM> All threads completed. (succeed 0 / failed 0)
<OSM> All threads completed. (succeed 0 / failed 0)
<ID:0/004> Added!!
<ID:0/004> Odin v.3 engine (ID:4)..
<ID:0/004> File analysis..
<ID:0/004> Set PIT file..
<ID:0/004> DO NOT TURN OFF TARGET!!
<ID:0/004>
<ID:0/004>
<OSM> All threads completed. (succeed 0 / failed 1)
<ID:0/004> Removed!!

The phone still has the green "Downloading" triangle -Do not turn off target! showing... Any suggestions for what to try next?
