Hello guys and merry Xmas!!

I have a question regarding flying the Mavic Pro in controlled airspace!
So say a small German airport agreed to let me capture some aerial footage. The local authorities have been informed. I got a call from Tower, permission to fly in controlled Delta airspace is granted. Now my Mavic wouldn't even start because the firmware has hardcoded NFZ. So I go through the process of unlocking the NFZ through DJI (DJI map says "Restricted Zone Unlock Unavailable", is this a problem?). Now what do I have to do to unlock the 1640 ft (500 m) ATO altitude limit? Tower could give permission for vertical takeoff and 2500 ft AGL which is 762 m!
Besides: Germany officially allows 50 m AGL (164 ft) in controlled airspace at international airports if 1.5 km safe distance to the airport fence is held without any further permission. Does DJI have this implemented? In other words: Can I unlock "yellow" zones on the map myself?

I am afraid my drone won't even start the motors because of the restricted zone lock! That would render all the praparations and efforts useless.
