How To Restore DRM Keys After Unlocking Bootloader on Xperia Devices (Lost DRM Keys)

If you have unlocked the bootloader of your Sony Xperia device, you know that a lot of features will disappear because that is how Sony has built the system of its devices. Once you unlock the bootloader, DRM keys will be lost and you will be unable to access a lot of features.

Sony creates some of the best Android devices. They have great cameras, great displays, water-resistant bodies and a firmware close to stock Android. Sony has been very supportive when it comes to modifying Xperia devices.

They have a dedicated guide to learn new users how to unlock the bootloader and do other things. But, at the end of the guide, there is a warning which says that DRM keys will be lost once the bootloader gets unlocked.

On most Android devices, there is only one downside of unlocking the bootloader and that downside is loss of warranty. Once the bootloader is unlocked, the warranty is voided.

On Sony Xperia devices, there are more downsides. When the DRM keys get lost, a lot of features are lost. Camera image quality decreases and features like X-Reality color management, active noise cancelling and BIONZ image processor no longer work.

As you can see, you lose a lot of things when you unlock the bootloader and this has prevented many people from doing so.

But thanks to the amazing developers, it has been possible to restore most of the features even after you unlock the bootloader. A mod has been created which restores a lot of lost features. This has been made possible by modifying a few system files.

There are some of the files that have been modified:

  • drmserver
  • credmgrd
  • CredentialManagerService.apk

      • Thanks for the feedback. Much appreciated. One more question. I have unlocked the boot loader of my Sony Xperia Z3 but I have not yet root it. In case that I apply this mod and then root my phone, will I have to apply the MOD again? Is it better to root my phone and then I apply the MOD?
