All except that one batch of Switzerland white N9s come with PR 1.1 preinstalled. And there is no PR 1.1 update for it on Navifirm either. Tough luck, what can I say Have you tried updating it through NSU - maybe it chooses a different variant for the upgrade (generic Switzerland, 059M6M9)? Or in the end - have you tried to manually flash it? I'd personally try the Country Variant Switzerland CH Black 64GB V1 (059L5H1) for which there is PR 1.1 available - I don't think they differ in hardware at all.
