Fritz,
On my 7,1 with 10.15.7, it is "Firmware Version: 17P6610"

You must have installed an early Big Sur beta on your computer at some point.what is the version of t2 in 10.15.7? mine is 18P50347c. I am wondering why the firmware is different. It should start with 17PXXXXXX
You can revert, if you have another USB-C Mac and install Apple Configurator. The process will delete all the data on your internal storage.So now I can wait until big sur GM release ? T2 firmware cannot load back the old ones ?
