Don't mean to hijack you're current boot problems but I had a major panic this weekend when mine (2021 GT410) wouldn't open regardless of the pulling pushing and massaging. Had closed it carefully with my daughters hockey bag inside, no slamming and no loose straps over the latch, (I've done that before and became very familiar with the emerging pull cable mechanism)
Both the door switch and the key fob were working the solenoid and could hear it activate nicely. But the boot was fixed solid even when pressing and pulling.
Them tried the pull cord. On first pull the cable moved as had expected it to, some slack then felt like it was about to open, then it just went solid. Really thought I was going to break something pulling so hard.
My neighbour, a prestige car recovery guy who is an expert at opening McLaren's with flat batteries came to help.
We pressed, pulled, activated, massaged for 15 minutes. Nothing.
Finally he was using such force that the car rocked back and forwards, while was pulling the cord, and it popped open
I took a photo of the culprit. A plastic tab on the end of one of the bag straps was sitting between latch and hammer. Perfect fit to slot in and somehow prevent both the solenoid and pull cord from activating the hammer. I think his rocking action must have made the bag roll forward slightly, just enough to release.
In conclusion, beware of anything getting into the gap in the latch.
