Looking for legit refx Nexus 2 update file anything BEFORE version 2.7.3

[Sinistasoundz]

Hey guys im a legit owner of nexus 2. Im looking for an update installer file of any version between 2.7.0 and 2.7.2...i recently installed 2.7.3 and i've been having problem and i wanted to roll back to a previous version. I tried refx support and they dont give previous versions to customers...and they didnt find the problem so far. Tried reinstalling and still have problems

I have since erased my older updated files. I checked everywhere on the net and cant seem to find them anywhere......

I am presently working on a project and i need to roll back to finish....Anyones help would be greatly appreciated.

Thanks
