 For some time we were in dispair. It looked like the only way to get a cam downgraded was Canon Support. They are able to do so if you ask/beg and - in most cases - pay a fee for service. (And if you got scared by this manual you may want to do it this way ... each time your cam gets updated ...)\\
-Fast forward ... ML user Apollo7 showed up. He found a way to overcome this lock by tricky handling the battery door during firmware update. (Sounds scary but behold! **No** cam treated that way got broken and reported to us! None!)

-Main dev at the time was a1ex and he found a flaw in Apollo7's handling routine which made it possible to get harmed under certain conditions. Very unlikely to happen but very unpleasant in case it did! He came up with an improved handling routine which we are promoting and endoring to be used: We call it **Method B**. Sorry about naming but it is how it is ...

 Nowadays a lot of cameras got this kind of lock and all new camera firmwares work like this!

 - Cam will teil you it cannot find the firmware file. First check and verify FIR file is in card's root directory. If it is actually there: This may happen with SDXC cards and older cams (Digic 4 generation). Explanation: Firmware update uses a very, very old software routine. It may have troubles dealing with SDXC cards. Use an SDHC or SD instead to run firmware update.\\

 This is a thing from the past. Before any PC could extract compressed ZIP without an additional program. It is a so called "Self-extracting archive". Any unzip utility will just be happy to extract it for you!\\
