Manual Roof Opening - Locked Convertible Top - E89

[MartyZ4]

My roof is in the closed position and locked with error code A68C, which is the hall sensor, passenger side, and almost certainly the wire. Is there a way to manually unlock the roof so I can lift roof shell 2? I've tried releasing the hydraulic pressure by turning the appropriate screw a half turn, but this doesn't seem to release the roof locks. Neither the key nor the console button release the locks, and instead the console button flashes red.

For context, the roof initially failed with the passenger microswitch error, and at that time it stopped while partially open, so I was able to manually move roof shell 2 to a position whereby I could replace (with much help and guidance from RobbiZ4!) the wiring for both the microswitch (which was broken) and the hall sensor (which was kinked and about to break). Obviously, I didn't do a very good job, since the hall sensor is now either shorting or broken.

I'm hoping I can perhaps jump a wire in the CTM in the trunk (which thankfully I can still access) to trick the CTM into thinking it's getting the correct signal from that hall sensor, but I'm not sure which pins I need to jump (ie which other wire would provide the correct voltage to release the lock, at least, or better, raise roof shell 2). There's some great advice here: https://z4-forum.com/forum/viewtopic.php?t=122363 but the link to the complete roof opening instructions no longer works.

Or is there a better way to unlock the roof and manually raise roof shell 2?

Thanks for any suggestions!
