ᐅ Looking for assembly instructions for an Ikea Avsikt louvered door cabinet, manufactured around 2008/2009.

Hello everyone, unfortunately I had to remove the blind from the Avsiktschrank measuring 60 x 121 cm (24 x 48 inches) because it got stuck. Now, what had to happen has happened... I can’t get the blind reinstalled. The current installation manual doesn’t seem to match the cabinet I bought back in 2009 (?). Does anyone have an installation manual for the "previous model" or know a solution? The blind is guided over a "first roller" and normally rolls up over a "second roller" when pushed up. There is a small piece of the blind attached to this "second roller." How do I connect the blind on the second roller with the main blind? Sounds complicated, and it kind of is. Any tips would be greatly appreciated!!!
