So, went to get some tools from the back of the car yesterday and found the tailgate won't open. Button on dash, fob long-press and handle all have same result - what sounds like it latching/unlatching. There is absolutely zero movement in the door though. It feels locked even though I hear it unlock.
Watched a video online regarding the ground cable in the cargo roof connector - looked totally fine when I removed it from connector, Joined it outside of connector anyway. No change. Checked fuse under glovebox and in cargo area - both appear fine. Destroyed the plastic around the latch trying to find the "secret hole" to release latch - mine doesn't have it as my latch differs from those I see the videos/guides.
The only thing that altered in any way was, when I had the grey connector unconnected I tried the auto open. Same noise as before but this time a slight movement at the upper part of tailgate. As if the strut was trying to push it open but couldn't because it was locked.
Hopefully someone here can help because I can't even access my spare wheel at this stage. How do I bloody open this thing???

This is what my latch seems to look like and this is the mess I've made...
