Do you just copy the TA/DRM backup img file to phone and use twrp to flash it, or are you supposed to connect the phone to computer and boot into fastboot mode where you run adb commands from the pc? Have been searching but not found any explicit examples, just mentions of 'flash with the drm img back to stock'.

But it won't flash yet.

So it seems I had the wrong ftf to flash with. I will have another go with this version: https://easy-firmware.com/index.php?...egory&id=18692, at the bottom.
