and i just tried the file on my ez-flash 4 and it worked perfectly you have to hold r until you see erasing OK and after it will show Flashing:XX%
There were occasions to use more GBA centric/pre DS firmwares and clients for the EZ1 through EZ3 but aside from the border glitch (hence the reset loader we suggest) on the DS side of things which would not trouble actually working and does not apply to the GBA things tended to get better with the EZ4.
Still any number of old versions of the kernel and client should be available from

and

also

It is not the first time I have seen Lady Sia pop up in the last few weeks and although I always thought it ran OK it does warrant a further look.
I have installed v1.680 (datecode 20060726) firmware from the links you gave me .
Now the Lady Sia works
Many thanks for help
