Or they are gone forever?</P> Thu, 20 Nov 2014 04:00:31 GMT https://community.sony.co.uk/t5/z-series/drm-keys-restore-after-relock-bootloader/m-p/3322954#M40656 alirezanasibi 2014-11-20T04:00:31Z https://community.sony.co.uk/t5/z-series/drm-keys-restore-after-relock-bootloader/m-p/3322955#M40657 <P>If you unlock your bootloader you will loose DRM keys and relocking will not bring them back, You need to root without unlocking the bootloader then backup your TA partition - Then you can unlock your bootloader and should you wish to relock it then you need to restore the TA partition to reaquire your DRM keys, However as far as I'm aware there is no way yet to root without unlocking the bootloader, But check over on XDA for more details</P> Thu, 20 Nov 2014 09:25:34 GMT https://community.sony.co.uk/t5/z-series/drm-keys-restore-after-relock-bootloader/m-p/3322955#M40657 Thommo 2014-11-20T09:25:34Z https://community.sony.co.uk/t5/z-series/drm-keys-restore-after-relock-bootloader/m-p/3322956#M40658 If there is a way to root without unlock please share with us.
