Even if your phone is Unlocked (Bootloader is showing 'Unlocked') just ensure that when you give it to any service center u change it to 'Relocked' status. The first thing these people do is they flash your phone with RUU. Once they do it, bootloader status changes to 'Lock' something which we cant do as of now. If you keep the phone in 'Unlocked' status then they won't be able to flash your device & will easily come to know that you have unlocked your bootloader.
I got my device back in 2 weeks. Its kinda they know that many Desire V are having problems with motherboard so they don't take much of a hassle of trying different things out to make your device work. They simple replace the motherboard.
