Thought I'd post it up here if anyone ever needed it, not sure if I can link to the forum I found it on but if you Google "T311XXUAMG1_OXEAMF4.part1.rar" you should find the source.
As far as I can tell it's universal between both T310 & T311, possibly T315 but I'm not sure?
I compared this file to a one I downloaded directly from my T310 using Heimdall-Frontend via Ubuntu and both had the exact same entries/contents.
I believe this PIT file can be used via ODIN whereas one generated/downloaded using Heimdall can't due to some security check.
It's a good idea to backup this file in case you ever mess up your devices partitions.
