Updating the canon 30d dslr online

Some of the contacts in most Canon appear to be gold plated so shouldn't be "scrubbed" with anything abrassive that might damage the soft gold coating.

Also, gold doesn't corrode (that's why they use it), so you shouldn't need a strong deoxidizer, either.

If you already have the latest software, you don’t need to do anything! Download the firmware update file from the Canon website to your computer.

If you are using a Windows PC, you will need to extract or unzip the downloaded file.

There are full instructions on the Canon EOS 30D firmware update page on how to do this.

Your camera powers up and seems normal some of the time, you can access the menu, but it sometimes seems to stick in one mode or another.

Let it sit for a long period of time, allowing any and all remaining power in the circuitry to gradually drain off.

Some have had success letting the camera sit for just half an hour, 45 minutes or an hour. If your camera is 4 or 5 years old, you might want to replace the small, silver memory battery with a new one at this time.

Or it won't format a memory card or doesn't write properly to the card (in this case, also use a flashlight to closely inspect the pins in the memory card socket and the socket end of the card itself, to be sure none are bent or damaged).A few drops of isopropyl alcohol (inexpensive and widely available 70% "rubbing" alcohol is fine) on a clean cloth will remove any oils, which are the most likely thing to cause problems with batteries.An alternative is to use disposable computer keyboard/monitor wipes, most of which are pre-moistened with isopropyl alcohol (check the label).There's simpy no guarantee this will fix any specific problem. The latter is often a CR2016 or CR2020 lithium or similar in a little tray alongside the main, rechargeable. Among other things, this "date/time" battery serves to maintain the clock and date in the camera while the camera is turned off (your computer has similar on the motherboard).It lasts a long time, up to five years typically, but does occasionally need to be replaced.
