ok so either this is now gone or im completely blind.
I need the stock splash file so i can exchange my phone under warrenty. (the power button is dying and its getting extreamly hard to unlock my phone)
well after some more searching i have found another spot with splash screens and boot animations:
one of them says its the stock one.. havent tested yet, but downloaded it.
EDIT2: yes this is the correct file
now i can just reflash the stock rom, turn s-on, and reflash the stock recovery...
