Z5C has an option now to check/un-check OEM Unlock (bootloader)
[I](tap mutiple times on buildnumber in 'about phone' and go to 'developer options')

But it seems very uncertain what the DRM loss is. MyXperia, maybe low light camera features? And etc.
I do not take any responsibility of any DRM loss.

Thanks for sharing this.

I take the opportunity to ask. Sony voids the warranty if you unlock the bootloader? (Like Motorola and almost every other company with the exception of Nexus/GPE devices and maybe some more).

Shouldn't be the case in EU. See [INFO][EU] Rooting and Flashing don't void the warranty or . However I don't have any experience with this myself.

Here is a list of supported devices if you want to keep track.
developer.sonymobile com/unlockbootloader/unlock-yourboot-loader

I got my z5c yesterday. If I follow the step-by-step guide for z3c (because z5c is not listed, yet?) and call *#*#7378423#*#*, go to service info > configuration > rooting status, it says "Rooting status: Bootloader unlocked allowed: yes".

Continuing the process and providing a mail and then my IMEI, I received a unlock link for my Sony Xperia Z5 Compact using the Z3 Compact guide. I have not tried to use it yet but I will when I get home.

I tried doing it but I can connect to fastboot. With z3c, this was done like this:

1. Turn off your Xperia™ Z3 Compact.
2. Connect a USB-cable to your computer.
3. On your Xperia™ Z3 Compact, press the Volume up button at the same time as you connect the other end of the USB-cable. For Windows users, when asked for a driver, point to the usb_driver folder where you placed the android_winusb.inf-file, and select the Android Boot loader Interface-file.
4. When your device is connected, open a command window on your computer and go to the platform-tools folder within the Android SDK folder.
5. Enter the following command:
fastboot devices
6. Verify that you get an answer back without any errors.

This does not seem to apply on z5c. Any ideas?

If you mean Enable OEM unlock, then yes, I have that checked. I also have USB debugging enabled.

I tried and the device boots into fastboot mode just fine. It also is listed normally using
fastboot devices
But I am too much of a coward to try
fastboot oem unlock
because I bought the device mostly for the camera and don't want to break it.
