WARNING!! 5D MK3 refuse update from 1.2.1 to 1.2.3 if powered with third party battery

I updated mine with a 3rd party battery. Both my Canon batteries were low. I guess I was lucky that the update went smoothly.

Hello,

I am still running version 1.1.3. but I consider to update to version 1.2.3.
I am wondering if any one does have problems using 3rd party batteries (I use phottix) after the update?

Kind regards!

I just upgraded from 1.2.1 to 1.2.3 with Canon OEM battery. Still can use Wasabi battery (that can be registered) after upgrade. It should not be a problem.

I could be wrong, but this doesn't seem like it relevant to the 1.2.3 firmware at all. More or less, this seem like the 1.2.1 firmware problem. OK, what I'm saying is, I remember when the 1.2.1 came out, people were having problem with it, some even has problem even with guanine battery. I suspect that if update from earlier firmware prior to 1.2.1, you may not have experience this issue, or if this were to update from 1.2.1 to 1.3.0(for example) the problem may still be the same.

Just a thought.

For sure, you absolutely right. It has nothing to do with the 1.2.3 version but clearly it is 1.2.1 which does search for an original Canon Battery prior to search the 1.2.3 file on the memory card.

As you write, the issue with the batteries came up with the 1.2.1 version and did not exist with 1.1.3

I upgraded last night using some after market battery with not even a hiccup.

FYI and YMMV
