How to downgrade firmware on my EOS 600d - ML

Hi,

I'm going for a weekend away this friday, and would like to install Magic Lantern on my Canon EOS 600d/t3i (I've got a few plans and it could come in handy).

Problem is, the Magic Lantern download for the 600d is only for firmware v1.0.2 (see here ), and my 600d is on v1.0.3.

I found this , which suggests I can downgrade my firmware to v1.0.2 (using this method) by using a download from here .

Are there any potential problems for doing this? Is it safe? I would be glad to have your opinion.

(I need an answer by friday noon, otherwise don't bother replying.)

(I have also posted this in the "open talk" forum.)

Thanks.

Download from Pel.hu, unzip, put it in the Root folder, put the SD card in the camera and do a firmware downgrade. Simple and worked with my 6D and 7D.

About Magic Lantern, read this page https://www.magiclantern.fm/forum/index.php?topic=8286.0

Especially "Don't remove your card too fast!"

Firmware from Canon page vs firmware from Pel.hu. Same sha256 checksum and safe to use.

Thanks.

I took the plunge last night - everything went smoothly and ML is running fine.
