SV05 Nozzle clogged

Hello, I have the SV05 and after the second print the nozzle is clogged. Have tried using the needle method and pulling the filament out, but the filament is stuck and won’t come out after preheat either. How can I fix this? Thank you.

Could you pls refer to the video to clean the extruder? After cleaning, the material can be fed and discharged normally before printing.

@sovol3d Is there a video on the SV05? There are minor differences that worry me trying to take it apart.
