It worked! Just deleted all registered batteries… Thanks ogalvan.

Those who didn't have any problems in the first place: did you have registered battery info?

Why access registered battery info during a lens update when all you should be concerned with is the current battery charge? As a software developer I think this is one crazy bug. (Not that I code bug free ;))

I find it a little annoying that they come out with a firmware fix for this lens which apparently sold in huge amounts, but can only be updated by the people who have the very newest cameras, which is probably a fraction of owners.  I just sent a buch of lenses back and forth to Canon to get them adjusted right, and I'm kind of tired of spending money on shipping...

All good here! I hadn't tried the firmware update before reading the battery info solution, so I went that route and it worked like a charm. Thanks ogalvan!

Same result here with the battery registration delete after a failed update. 

1st attempt fail was 2768% with camera halt (firmware listed as 1.1.0 initially)
2nd attempt fail was 64% with shutter and shutdown (firmware listed as 0.0.0 initially)
Visit CR Forums, kill reg info
3rd attempt success without issue. 

BTW... battery that succeed was at 77%, so full charge doesn't appear relevant.  Espescially considering the first two failures were with a 100% battery.

Canon... really... REALLY?  That's just lazy.

I would guess less "lazy" and more "we have a bug with battery info registration we didn't know about and didn't see (on the new cameras) in our testing lab".

The "lazy" was more referring to QC on the firmware by obviously not testing the update on enough different body/scenarios to ensure it would work.  I do realize they can't test every scenario though, but a body with registered batteries seems like a fairly common one. 

But, yes... I see new body firmwares coming soon! ;)

I don't think it's happening to every body with battery information registered; my 5d3 has battery info registered and the STM upgrade went through first try. But it is clearly happening to some combination of battery, body and battery information registration. I wouldn't rule out an unforeseen interaction between some custom setting and the battery registration.

I haven't been following this closely enough, but I wonder if maybe the issue is with battery information registered from counterfeit or third party batteries? Maybe the people who had the issue and then succeeded after deleting the battery registration information can chime in on that.

All of my batteries are legit but I had the issue. It can be due to other factors like you said but I also posed the idea that it could be earlier releases of the lens? I pre-ordered and got it pretty much on the week of release.

I had the info of three genuine Canon batteries registered when the update failed. One came with my 5D3 and the other two were ordered from Amazon directly. No third party sellers.

Got mine from a large electronics store during the first week after the release so I'm pretty sure it was from the first or at least an early batch.

Unless I'm being pattern blind, I'm not seeing a date code on my 40 STM. Which seems odd to me.

Some lenses don't come with date codes anymore. They just have a serial.
