I do have an OMU, came with the GECB. It’s a blue one though (H21) all I had info on was the H1 & H2 (2mb & 4mb). The blue OMU worked with the V1 GECB to backup the job and baseline but with the new GECB I never got the OMU menu. I had ordered a blank H2 OMU from Alibaba so I read the H21 with a programmer and burned it to the H2. The V2 GECB recognized that OMU and I was able to proceed. I got an error when I tried to load the old baseline to the new board though. Later I found out that the new blue H21 OMUs are a different manufacturer and the V2 GECB (or it’s software) won’t recognize it until you first load a patch from a special OMU. Eventually I got a hold of one and did that but it didn’t get me any further. My original work around seemed to be just as good.
