Part of my problem is I only have one end of the tape, the other end is sucked back up into the tape
pop it open..tape it back together. You only need it to work once to transfer it
Yep.
You are going to have to open up the tape either way.
I'd get a throwaway tape of the same brand and open that one first - don't dismantle it - just open it up and set it aside.
Then open up the broken tape, fix it up as best you can, and then put it back together. If you run into problems trying to figure out how it all goes back together - use the open throwaway tape as a reference.
