**PLEASE HELP** My T3i won't boot

[supercoolsix]

Hi everyone,

I'm in panic mode.  My T3i won't boot.

I had Firmware 1.0.1 installed with Dec2011 ML installed.

I wanted to update toe ML 2.3 so I installed Canon Firmware 1.0.2.

After installing 1.0.2 i got the flashing red lights (probably because the ML2.2 wasn't compatible with 1.0.2 and still installed)

How do I go about fixing this.  Every time I enter an SD card the camera won't boot.  But it turns on without an SD Card.  PLEASE HELP!!

I got super excited to film my first born and now I'm stressing because I think I bricked my camera.  Being in panic mode, I tried reformatting the SD card I used to upgrade the firmware (not sure if that's the right thing to do). 

PLEASE HELP!!   

Thank you in advance!!

If it turns on, it's not bricked. Format the card.

But when I put in a card it doesn't turn on.....

If it turns on, it's not bricked. Format the card.

When i put a blank 16GB SDCard, it won't boot.  How do I reformat it if the camera won't boot up?  Via PC?

I was able to disable the boot and then uninstall ML.

Thanks for the quick response...

I will start from scratch. wish me luck!
