Sorry if this has been asked before.
When trying to install the May 13, 2013 Nightly Build, I'm getting the message:
Firmware update program
Update file cannot be found. Please check the memory card and reload the battery and try again.
When I unzip the v2.3.NEXT.2013May13, there is a 1100D-105.fir, but no .fir for the 5d2 within the zip. Should I reuse another .fir for the 5d2?
I've gotten the NB (nightly build) to work twice before on both my 5d2 and T3i, and each time had a problem like this. IIRC, the firmware doesn't report a Nightly-Build, but v2.3. It's not a confidence builder. Obviously I'm doing something wrong, like leaving out a step. Or I shouldn't use the 5D2 in "Non Magic Mode" to format the CF card prior to installing the NB?
Should the NB .zip have a 5D2-212.fir in it? I've got one dated from 2012.July.23, which I think is from the Canon firmware update.
Or should I get the 5D2-212.fir from the v2.3 "Stable Release"? Which is also dated 2012-July-23. It does seem odd that the NB .zip has a .fir for only the 1100D. Is that "as expected"? Because it wasn't in the v2.3 Stable-Release? Or there haven't been firmware updates from Canon for the 1100D?
Sorry to be slow, but it is perhaps from an excess of caution to try something that could brick my 5D2. I really, really want to explore automated dot-tune and RAW histograms.
