Hi guys! :)

i'm new here and first of all: dont worry about my weird english ;)

i've got a problem with my moms Z550i.
it has the old buggy release-firmware (R6BA033) on it (with sound bugs in java, "operation failed" when i try to open videos and pictures sometimes and so on..)

well.. the phone itself works great, but when i try to update it (with SEUS or XS++.. doesn't matter) it simply does.. err... nothing when i connect the USB Cable while pressing the C button :eek:

it seems just plain dead. windows doesn't find new hardware (and doesn't play the "usb device connected-sound") and nothing happens :(

the fastport connector itself is working. i can charge the battery as usual and when i connect the DCU-60 while the phone is powered on, it asks for this "file transfer or phone mode" thingy.. so i assume the contacts of the connector do work.

well.. i've got a similar problem with a water-damaged K750.. it doesnt do anything at all when i try to connect it to flash it too. (the phone itself is working.. i just want to update the firmware because the firmware that is on it now is the oldest available (R1A044)).

i'm running out of options

any ideas?!
