[Prabhu1980]

I was experimenting with locking and unlocking of bootloader after a crash and then I relocked my bootloader to alas Find out that I have lost drm keys. Sony please restore it for me. I wanted to stay on Sony official rom and now I face lots of video and camera issues after relocating. I was only warned of losing warranty not the drm keys

Are you sure?

Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader.

I'm sorry to say this but If you didn't backed them up they are forever gone. The only alternative is to replace the motherboard which will be expensive.
