This info, for a 745i with the EGS 6HP, has Reset/relearn values as menu item 7. It's on a NT510.

Nope - not the same. A Reset/Relearn is an adaptation reset - to be avoided unless you have replaced major components in the transmission.

A software update requires a copy of the new firmware for the transmission controller (EGS) and a tool (laptop and software etc.) for programming the transmission controller. Note that I said transmission controller and not the transmission itself. Transmissions aren't programmed but controllers are.

The hand-held scanners will not update software/firmware in the car (in general).
