Ok, I got XS++ and tried putting on some custom firmware? it got to 160000 and stopped and didnt change from saying that so I just stopped it.

So I then used the Sony Ericsson update program, and now there's slight functionality, well, more than before, like whenever I switch the phone on a purple box (like when a message would appear normally e.g. your balance) appears and it has a tiny font with random spaced out letters. whenever you press the power button, it brings up the normal menu showing the profile options, but it just has the pictures at the side for each profile, it doesnt have any text beside them.

any ideas?
