It's because of Canon.

The latest firmware update for the 7D apparently included code that implemented a firmware update counter and a limit to how many times the firmware could be updated. Tramm hit that upper limit and his 7D will no longer allow updates so he is left with the last one run.

The firmware update process does not allow going back to a previous version so he is effectively "locked out" of going forward with the 7D.

I fully expect Canon to find some way to do something similar with the T2i. While they are not making a big "scene" about it they appear to have decided not to "tolerate" reverse engineering of their firmware code.

Constant requests to Canon to include the audio control and perhaps other features desired in a future firmware update may eventually move them to do what they did with the 5D MkII in the way of adding audio control and updated frame rates.

Panasonic has included code in their firmware that "blocks" unauthorized updates or changes to the firmware in the GH1.

I guess we have a similar situation to IPhone jailbraking - it's legal to do but permissible to prevent it.

I was planning to buy three GH1 for my wedding work. But I was late to the game that all the new GH1 out there are unhackable. Maybe Panasonic think I will go up to their high end Panasonic camcorders, it turns out I bought three T2i... and I'm loving my t2i.

Hi

First of all a biiig thank you. Thanks a lot for all the work you have invested in the community. There is just not this video infrastructure (beginning with stores) here in Europe or people like Mr. Hudson who help other people save a lot of trouble.

can someone maybe make a video tutorial how to hack the t2i? how to install it, im really a beginner and dont want to break my camera.

Thanks a lot in advance

Kind regards from Vienna, Austria

Its all right here:

However, you need to understand that this is testing phase of a product that is not yet even doing what is actually the ultimate goal. There just bits an pieces of what Magic Lantern is about, working at this point for the T2i.
