Sorry to bring this up again, but shouldn't it just be called NP355V4C-S01, otherwise we'd have to make versions for every language ( RU, DE, FR etc. ).
Just came across this because I'd need the NP770Z5E-S01 ( my version is called NP770Z5E-S01DE ) to be added to the database, but I'll make a new ticket tomorrow and post a validation.
