Short answer I got and old FIRM WARE as it was being loaded i renamed it/replaced the one about to be LOADED with the OLD one(one your happy with)


I searched online got my old firm ware renamed it to a current one say 2.0.0.fir its sucks it up
loaded it with EOS-UTIL then on the 7D it says upgrade 2.0.0 with 1.23 FIR and Voila!

I hardly use Live View on my 7D, but yesterday when I was trying to focus on something, Live View hunted for a abnormally long time. I thought it was a fluke, could it have something to do with this? Everything else seems to work fine though.

Imagine this marketing meeting at Canon: Q:"how do we get our current satisfied 7D owners to open up their wallets for a new 7DII in 2013?" A: "let's release a firmware upgrade that breaks their current cameras." Many high-fives ensue and a bright spark gets a promotion.

Just to make sure everyone here followed the same procedure I did. The new battery trick...its not really a trick. That was actually explicitly listed as a REQUIREMENT in the instructions for flashing the firmware. Canon was fairly explicit about the fact that the firmware upgrade would not fully "kick in" until the camera was powered off and the battery removed for a little while.

If you flashed your 7D and have not yet powered it off and removed the battery, do so now. It is a required part of the upgrade procedure.

Did that, exactly as the update instructions said.

This issue frsutrated me so badly, as I had an essentially worthless body on my hands, that I started researching how to roll back the update. In the process of finding out that such a manuever is essentially impossible for the consumer, I hooked the camera to my laptop and realized through EOS Utilities that I only had Firmware update 2.0.0. With nothing better to do, I went ahead and installed 2.0.3 and it appears to have solved my problem. Otherwise I had every symptom the OP was experiencing, to such a bad extent that I couldn't use the camera. I've shot 120000+ images with the body, so to have it just go kaput after a firmware update is totally unacceptable and an obvious sign that the update was the clear culprit. Canon needs to figure this one out in a big hurry.

You might try reinstalling the update and pray that solves the issue.

DID you read up on few of my posts here, On a PC its basically a bait and switch get the EOS util to think you giving it he current firmware say 2.03 and just before it loaded it rename and replace it with the old one renamed to the current firmware (some guy online had all the firmwares stock piled, so you could go back to any version you want)

if you have a PC i could guide you, MAC only im a bit lax on the file tricks

Just wanted to let you all know I redid the firmware update twice (same procedure as the first time, followed Canons update instructions). The AF seems to be OK now..
This is really strange!

This topic has been quiet for a long time but it was the only answer to mu IMMENSE frustration with 7D.
I have been through hell with brand new 7D body since day one (Oct.2012), it had and still has exactly the same problem other were mentioning: intermittent HEAVY front focus while showing green light confirmation in the WF.
The lenses affected are in the 17-50 2.8 range of any make: be it Canon`s original 17-55 or Sigma 17-50 or Tamron 17-50 anywhere between 10-30% of images end up useless with catastrophic front focus AF failure. It has nothing to do with AFMA, all lenses focus correctly - until camera occasionally goes wild. At medium to long distance the error can be measured in meters not inches. Medium to low light conditions can 'improve" failure rate up to 50%!! I sent the camera back to Canon for check up almost straight out of the box, got it back the same with remark that "camera was within the specs" and since I had Sigma 17-50 2.8 OS at the time "it might not work correctly with Sigma." BTW that same Sigma worked flawlessly on my 40D and 50D...So much about canon`s support. So I sold Sigma and got canon 17-55 Is - only to get same if not worse results... >:( so I got Sigma lens again. Camera came with 2.0.3 software installed so I could not compare with older versions but it seems that downgrading to 2.0.0 or lower worked for someone here, right? Funny thing is that other lenses I have (50/1.4, 70-200/4 L IS, 85/1.8, 200/2.8 L, 18-55 kit lens ) work more or less fine, 18-55 3.5-5.6 cheapo kit lens being dead-on 99% :o Also, I tried 3 brand new 7Ds (including mine) with 2.0.3 firmware - all three had exactly the same problem. Any comment and suggestion would have been HIGHLY appreciated. How I can get and try to downgrade firmware and is there any risk associated with that? Thanks...
UPDATE: downloaded version 2.0.0 (would not go further than that) just waiting the comment is it safe to take this downgrade route.

So, I am out of hope, downgraded firmware to 2.0.0 and after about 100 shots got again that dreadful front focus error on Sigma 17-50 2.8 OS at 17mm. Even EF-S 18-55 3.5/5.6 had a few bad ones at 18mm, not as catastrophic as Sigma but still way out of focus. Time to ditch 7D and move on I think...too bad as I otherwise loved the camera.
