Request: Root for Samsung Galaxy note 2 n7105XXDLL5

Hi guys,

I just bought this phone and I just want to flash it with a custom ROM. I did not find any root hack specific for this model and firmware. Is there any chance you are willing to create one? Do you need me to upload this recovery img file for you? Is there a way to flash custom rom without rooting first?

Thanks for any help, I appreciate it!
