Update on BC Version on xbox one prevents save game transfer

Hey,

I want to get my old L69 saves to the remastered GOTY version. When I start the backwards compatible version of the classic GOTY on Xbox one, an update prompt for a 6 mb update pops up. There is no option to actually confirm that update, the only clickable option with the A button is cancel. Clicking that or hitting B means I have no xbox live connection, therefor no access to the cloud and to my old saves.

I am not the only one with exactly that problem, I few other people on a Trueachievments thread described the same stuff. Is there any workaround I have not yet seen? The dic drive of my old 360 is not working anymore, so I can’t start the game there.
