Hacking I can't update the firmware... help

[Lodox]

Well the topic says it, basing on a guide i found, u have to copy ez5upldr.bin to root folder of microSD card, and then turn on the DS, boot the EZ-Flash V and press R, hold it. It should take me to firmware update screen, as the guide sayd, but it's not. Nothing happens. Why? How do I do it? Please help, thanks in advance

EDIT: Oh im using EZ-Flash V with expansion pack and 1gb microSD japan kingston card

EDIT2: NEVERMIND THAT Im sorry my bad im so stupid I just had to press R button earlier than I did before
