i don't really remember all that much how to do this but to start you'll need 0x3435444431354436444432444135304145423731434537413532383443463845 unless it's changed since then quickbms and UE4.bms never could get customs to work so just replace an entry
as a batch command to execute that would be quickbms_4gb_files.exe UE4.bms *.pak x
