U2518D, installed M2T103 over M2T104, #3

Hi! Ehm.. MAYBE I have done the same. :S Brand new U2518D with factory M2T104, now with M2T103. :S

Has anyone found a way to get back to M2T104?

It was a bad move. Actually I was wondering for half a second "maybe they are using a strange version numbers...?" and pressed Update before thinking twice. Congrat to myself.
