??? I thought the two (M* and A*) are optically identical and that the only substantive difference is the mount.

It seems like there is always a report from someone somewhere who has problems doing a firmware update. Failure is almost always traceable to not following directions, using a depleted or faulty battery, and/or using a bad SD card.* I am pretty conservative about updates and have only done three since buying my K-3 Spring of 2014 (initially after purchase, once more to get the runaway mirror mitigation,** and the current update to v1.30). I did the v1.30 update recently (I don't remember why) with no problems.

* Using corrupted and/or improperly formatted cards seems to be more common than battery problems. Still, the number of users who have bricked their cameras during an update is fairly small.
** Unless your K-3 is fairly early production, runaway mirror should not be a concern for you.
