Looking at the show flash output they were trying to keep an 8.0.30 image which is not UFI and had boot loader 10.1.14. Not doing going to work at all. I suspect if they had updated to 8.0.92/95 and UFI on the primary, then loading 9.0 into secondary might work? Or copy pri to sec then put 9.0 on pri.Must be a typo, you can upgrade from the UFI firmwares to 9, same as going to 8.0.95. I went directly from 8.0.95 to 9.
I think the issue for this poster was that you have to jump in with both feet on 9.0*, both primary and secondary boot need to be 9.0* can't keep 8.0.9* on the secondary.
I think I'll test that on a spare 7150 this weekend; worst case I have to flash it from uBoot to an older loader and non UFI image to recover.
