I recently woke my M8 up from a long sleep and noticed the info button no longer worked. Everything else seems to work. I found one post recommending taking the battery out and waiting 5 days and waking it up again to see if that fixed it. Part 2 was that if it didn't to try finding the latest firmware and re-installing it. I'm currently on part 1. Anyone heard of this problem, and have any other suggestions if this doesn't work. If not, anyone know what a service is likely to cost from Leica and where I am likely to have to send it to? Never done that before. Anyone know how long it's likely to take to get it back if I do? As a side issue, a couple of my lenses aren't 6 bit coded. If I wanted to get that done professionally, I suspect I'd have to send it to the same place. Anyone know how long that takes Leica to do? Thanks!
