Same here,
I'v been looking for a week (sinds I bought the phone) now.
All I want is to remove al vodafone crap (drebrand it). I Have XS++ and I understand how it works and all but dunno know wich of the hundreds of firmware i need.

On XS++ i tryed to customize system files but after i restart my phone nothing is changed..
