Restoring DRM keys / Warranty Claim

Hi there,

The headphone port on my Z3c has decided to start dying on me/being really loose about 2 weeks after I decided to unlock it all :/

I have returned the phone to complete threeUK stock 23.4.A.0.546 D5803 & relocked the bootloader, How do I go about restoring my drm keys from here? I made a back up of the keys when I first got the phone, I have tried launching TA-backup but it doesn't give me the option to restore them.

Many thanks!

Who supports warranty claim?

If I buy it from Amazon, do I call them or Motorola?

Edge is at Samsung for Signal Issues - Warranty Claim

So, my phone is in the hands of technicians with Samsung over signal issues.. Most likely there's nothing wrong, but I figured; free claim/support, why not? I've been keeping track which I think is pretty informative however the most recent entry is troubling.. I don't know if they're referring to new or old scratches.. I knew there were a couple very small scratches on it but nothing at all serious.. am I just being paranoid?
