Z310i Can't turn on BT

[Yazoo]

Hi!

i've got a problem with my recently bought SE Z310i.

i just can't turn on Bluetooth :(

it says "Bluetooth turned on", but it just stays off :confused:

i can turn it "on" as many times as i want.. it just doesn't work.

i already tried to turn the phone on and off a few times and left the battery out for a few minutes (was long enough to lose time/date) and i reset it to factory settings.

still no go.. :(

next thing would be the branding, as i've had lots of problems with my old D750i (T-Mobile version of the K750i.. mixed with the W800i casing in a different Color)

this Z310i is also T-Mobile branded, so i suspect that to be the reason.
but for flashing it, i would need a FW from the downloadbase here (which isn't possible to download for me..)

any more suggestions what to try?!

here's a video of that problem..
