my problem with all what happen and what i try
first of all, i use ML on my t2i for 3 years without a problem, so using it on my 70d was not my first time. i always wait until the SD card light turns off and i shut the camera off to take out or change the memory
I use the Nightly.2015Apr23.70D111B on my sandisk extreme pro class 10 95mbs (2 of them) and test it on my Canon 70D (W) (the wifi model)
I test the raw footage and other visual stuffs i use on my t2i, it work fine
i turn off the camera and didn´t use it for 3 weeks, i think that i have left the baterry on the camera this time
When i take the camera and turn it on, the led was black, and rear buttons didn´t work, the top panel was on and ok, and that buttons and settings work fine, the f on the rear panel was working with a digital lens. i also notice that the sd light was on and never turn off
i have done this so far:
- Change SD card
- Change batteries (i have 1 canon original and 3 non-original)
- left the camera without batteries 24hours
- install latest version of ML , magiclantern-Nightly.2015May31.70D111A, the led turn on with a ML text saying that it wasn´t the model for that ML, so i install magiclantern-Nightly.2015May31.70D111B, and it was back to black led without rear buttons working
- try a SD card without ML
- now i´m trying toi rebooy my camera, but i read that this model doesn´t have an internal battery that users can reach, so i´m trying with a tip for this that says that if i keep on without batteries the camera some minutes, and then some hours off without battery it might work. if it doesn´t, i will take it to service to reboot
