Hi everybody,
Is anyone able to provide for me the firmware 1.2.3 (5D300123.FIR) for my EOS Canon 5D mark III cuz i upgrade my camera with the last firmware 1.3.3 (5D300133.FIR) that don't allow the ML installation.
Thank you in advance for your help.
Best regards.
Greg.

<Sigh>
Top of page -> Downloads -> Download Nightly Builds -> 5D3.123
and read instructions.
You need EOS Utility v2.x to downgrade. Downgrade using cam's firmware procedure is not possible.

Hello Friends,
          I sent my Canon 5DMK2   and Canon 5DMK3 to Canon USA  for cleaning.  They replaced the circuit boards in both cameras and they installed the latest firmware.  Unfortunately, I don't have the original firmware that I used Magic Lantern on.   

          Can anyone send me the Firmware for my 5D3  1.2.3    and my 5D2  2.1.2
My email is:   [email protected]      and firmware must be MAC compatible...     Thank you,   Joe Ray

See post above yours.

And 5D2 is just simple. EOS Utility is optional.

I just wanted to report that I sent my 5DMK3 back to Canon and they graciously reset my camera firmware from 1.3.3 to 1.2.3 so I could load ML firmware.  I told them why I needed it reloaded and that I was using ML.  They said they understood and when I got my camera back, it had the proper firmware for Magic Lantern 2..... Thanks for the great help Canon.... at no charge...

You can already do this yourself with canon eos utility. Several posts about it.
