I've downloaded SETOOL2lite and it worked for me. Obviously you will need different firmware etc from me...
I chose W810 as phone type,
then for the files column, I added main firmware first(W810_R4DB005_MAIN_GENERIC_HN_RED50), then FS second(W810_R4DB005_FS_EUROPE_5_RED50)
I then put the .zip file (Custom Pack CDA102494_4_R3A_Generic_Trade_United_Kingdom) into the MISC Files. then pressed flash... all working fine and unbranded...
