liopass created an issue

Hello, please help, my 550D is stuck. I can't see the sensor cleaning window, the lcd screen is black. the red led blink one time then nothing. the autofocus still work but i can't take a picture. I had a error 80 but no more. before crashing i tried to uninstall ML with the firmware update but I did not see the "to enable the BOOTDISK flag ..." sentence so I tried to reinstall Canon .fir ... and nothing. any idea before I send it back to Canon ?? thank a lot. lionel

    yes i did (with the mac not the dslr because i can't) but still nothing. I'm on a mac and I've tried to make the card bootable with no success ?? do I need to do that ?

    Ok but no... I've copied all the files on the card including autoexec.bin. I just don't know if I have to delete the .fir files ? I've tried on 3 different cards. I've have been using ML for a years with no problem at all. It crashes after reinstalling canon software. Will it change somethg if I format the card in another 550d or not ? The dslr doesn't boot with no card in it.

    So, just to be clear.

    • if you start the camera without a card, what happens? LED blinking sequence, autofocus, viewfinder info, display status?
    • If you start the camera with a formatted card, what happens?
    • If you start the camera with a bootable card (prepared with MacBoot), and ML files on it, what happens?
    • If you start the camera with a bootable card, and this autoexec.bin, what happens? http://dl.dropbox.com/u/4124919/blink/autoexec.bin

    If it doesn't start, the LED blinking sequence should tell what's going on.

    sorry for the anonymous, it was written from my phone...

    • without a card : no led blinking, no display, autofocus is working, I got "busy" in the viewfinder on the top left
    • with a formatted card : the led is blinking one time (long) then same thing than without a card
    • bootable card with ML : LED blinking 2 times (the second seems to be longer) then same thing than before
    • with your autoexec.bin : the LED is blinking and never stops ... in the viewfinder everything is normal (no busy thing), but nothing on the display ... Is it serious, doctor ??

    So, the display is not working at all?

    What happens with the attached autoexec?

    When you ran ML firmware update (and you expected the sentence with bootdisk flag), what happened? Did you see anything on the screen?

    Were you able to reinstall Canon firmware? or you just tried and you couldn't reinstall?

    the display is not working at all. with the attached autoexec, the LED blink one time then i've got the Busy message in the viewfinder, and nothing more. when I ran the firmware update, I did not see the green message. The 550D boot alone (sensor cleaning screen) then ML was still available. Then I ran the firmware update with the canon release ... I switched it off and it never switched on again ... that's what I remember !

    With this autoexec, start the camera, and after 5 seconds the LED should turn red. After the LED goes off, you should get a log file on your card. Send me this file.

    Also try to press DISP to turn on the display, or hold the shutter pressed halfway on startup.

    You have upgraded to 1.0.9, right?

  11. liopass reporter

    when you say "with this autoexec", shall I copy it on my ML card, or on another bootable formated card? Because I've no log file I've tried DISP or shutter method but the display remains black ! Yes I upgraded to 1.0.9.

  12. Alex

    Yes, copy it on your ML card (like you did with the one from dropbox).

    You can contact me via google talk (it should be faster than here).

    so ... nothing comes out of this camera !! I'm gonna bring it to canon ! Thanks very much for your help and time. I'll keep you posted about that issue !

  14. Alex

    As you wish. The above tests showed we are still able to run code on the camera, so I could at least save your firmware and settings on the card and compare them to what's in my camera.

    What were you doing when you had ERR80? Maybe I'll be able to reproduce this issue on my camera.

    Tip: my gtalk address is in the PDF user guide.

    Hi Alex, just to inform you that my issue was a hardware problem. I just got it repaired, and now it works fine. I hope this is not linked with ML removal ... Thanks for your help however !!
