The bluetooth on my "w580i"is not turning on now! I press turn on, it says "turned on" but then the menu stays as the option to turn it on, and it remains off any ideas? ive tried reflashing it.

Did you perform any modifications? If you did, try not doing anything else other than flashing and then try again.

I'm not sure but maybe you could try another set of files/software? Most people solve this problem by reflashing...

Well i tried with the files i used before without adding any extra files, just fs main, and custom pack. no good. now i tried downloading a new main and fs and custom pack from topsony instead, all flashed fine, but still the bluetooth wont turn on

Hmm...

Could be a hardware fault there, you know...

Well it was working fine before i flashed it :S And it had just come back from the sony repair factory in south australia so it shouldnt be that?
had a search on these forums, there were a few people with the error, but without any solutions

Well, flashed back to s500i, going to send it back for repairs again i guess thanks for the help though.

hard luck...

Good luck with your new one then!
