Hello team. My camera doesn't work after updating/installing newer ML version magiclantern-Nightly.2016Feb27.5D2212 Update was successful. After update I tried to record video in LV mode and suddenly I saw an artifacts (green lines) on LCD screen. I stopped recording and pushed the button to do a shoot. But card led lighted up and didn't stop glowing for a long time not as usually for recording one photo. Camera was hanged. I turned it off, replaced battery and tried to turn on but the screen didn't light up. Symptoms: Camera LCD display doesn't turn on. Red LED doesn't blink when turning on power switch or closing battery and card doors. Small on top display works. I can see and change settings on the small display but sometimes camera hangs. EOS utility doesn't see camera.
Once when I turned on camera the card led blinked and the display lighted up.
After turn off it didn't light up again.
After an hours of investigating and tries I have found the method how to light up display. After reinstalling battery and a tenth of opening and closing the battery door the card led blinks and display lights up. When display is working Eos utility can see camera. But when I push the button to do a shoot, mirror lifts up, red led doesn't stop to glow and camera hangs. Only battery reinstalling can help to turn off camera. And again from the beginning tenth of tries etc...
I tried to update with Canon firmware but camera says that there is no firmware on card was found and hangs. Tried to update from EOS utility and after downloading .fir file from the PC it says something about press SET button on camera, but camera hangs with error no firmware file found.
Sometimes it shows me ERR70 on small screen. Once there was ERR80.
When display is working I can navigate through MENU, can format a card, can see a firmware version (original canon firmware) but LV doesnt work. Autofocus works. Even when display didn't turn on. But sometimes not.
Tried with ML card (latest builds, old builds), empty card, without card. Without card there is no notification on small display "NO CF Card". With empty card. Cards were formatted. No boot flag and ML files on card. Tried to put diagnostic autoexec.bin but camera didn't detect card with power switch is in OFF. Only once from 20-30+ battery door opening-closing Led was blinked but nothing happend. The only one error in log (see attachment). I was using older version of ML and for a couple of month and there were no problems.
If you need additional information please ask I will try provide it.
I am very disappointed. Please help.
