Cold Pull Not Working for Me

I have a bit of filament stuck near the nozzle that I can't remove with cold pulls. I partially disassembled the hot end to clear a jam, and I think I didn't properly get the nozzle assembly far enough up the hot end and there's probably a gap where the filament is stuck. I only have PLA and I see that cold pulls are recommended with ABS.

Is there a different temperature I should do the cold pull at with PLA?

Do I need to completely disassemble the hot end and nozzle to clear the residue? Can you point me at a guide on how to do that?

Would this be solved by the all metal heat break from Bondtech?

Thanks!

The Prusa knowledge base is real very good, I find Google the easiest way to find anything.

Have you worked through the Prusa help manual yet?

Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.

Sorry, almost simultaneous post with same link. But double holds better 😊 .
