need help

i change gdfs on my k750 and seems that the phone is locked(insert corect sim card)!!!!!!!!!!!i didn"t backup the original gdfs!!! what should i do?????????????

As far as I know, the GDFS is unique to each phone...

dear valex, u made a big mistake by not backing up gdfs, search gdfs files in top sony downloads umay get one.

dear yodafone!, gdfs is unique to each phone, know your model and download the required gdfs in top sony downloads for free, and if u load diferrent gdfs than your model u will be in sooop.

So i ll be able to revive it?

Valex! try customizing by flashing ur phone of ur region and can get the same in top sony downloads.

i ll try. but if doesn't work...

What do you mean whit this?

If it doesn't work, you'll have a brick.
Flash firmware from here, try to restore GDFS.

from where? what do you mean.?

What CID is your phone??? You just need to unlock your phone. You can try Sonic
but it depends what CID is your phone!
