I watched the videos. Both the videos show how to disassemble the mobile (battery and CPU) but not how to change the screen. The only video I found for screen changing is regardina a BV6000 mobile. Can I follow the BV 6000 procedure in order to substitute the LCd of the P6000? Or there something I need to know in order to not damage the mobile during the operation (ex. glue on the border, screws, heating the glass - which temperature - or the like)?
Yes, it looks similar.
If you don't know how to properly replace the display, i suggest you to contact any phone repair center near where you live. The risk to damage the new display or the phone is high.
