Iīve just read all the advices above, and thanx for them! I just have a problem that have not been discussed here yet, maybe itīs stupid but a novis really need some help here! When i try to install the driver manually direct from the divice manager I can not find/use the "Update Service USB-file". I Downloaded the file from sonyericssons homepage as a zip-file. When i extract it I just get two files, one text-file with information about the installation. The other filetype doesīnt my computer recognize. How am I going to solve this problem and manage to install the Update Service USB-file? Plz help me! Thanx

I'm done with the update, but now the problem is that it's giving me the message to "INSERT CORRECT SIMCARD" after turning it on with the simcard placed! PLEASE HELP ME ASAP!

It means your K750 is locked again..was it locked before,and then unlocked via 3rd party? Or maybe it's not a complete updating..
Perhaps, you need to re-update once again..and see what happens.

It wasn't locked when i first bought, and it's the middle eastern version so it can't be locked! It happened after the update! Is there anyway i can perform some kind of roll back?
Or tell me the way of unlocking through third part software. Thanx

I Re-Updated me cell fone as adviced by the person above but it still doesnt seem to work! Is there a way could unlock it for free by using the USB cable because in my country it's really hard to find people who can unlock cell fones!
