Taz5 Firmware update. Didn't note z or extruder offset

Okay, I messed up.
I neglected to note extruder steps or z offsets when updating firmware on a taz5
How to best recover?
:neutral_face: :blush:

the z-offset is mainly used for printers with the auto bed leveling which the stock Taz 5 does not have. The Taz 5 z-offset is based off the thumbscrew on the left side of the bed.

Thanks! Clearly a newbie.
