I have unlocked Bootloader but i dont have TA backup and No DRM Keys backup.. I have unlocked my Bootloader by giving SONY my IMEI NO. and putting the code in fastboot.. So i think SONY knows my warranty is void.. Is there anyway i can get my phone back to Original state with locked Bootloader and everything intact..
And most important Restoring of Warranty..
