I use
W810_R4EA031_FS_EUROPE_2_RED49.fbn, and W810_R4EA031_MAIN_GENERIC_HN_RED49.mbn. i chose the custpack W810_CDA102555_11_R2A_Generic_EUROPE_2 because on europe 2 german is on it.
I am not sure but i think i have it from the topsony downloads.

I don´t know waht the splash logo is??? It stops at the start screen. After turning on my phone first the SE logo come. There it stops.
